Lead Research and Development Activity for DOE's High Temperature, Low Relative Humidity Membrane Program (Topic 2)  

SciTech Connect

The Department of Energy’s High Temperature, Low Relative Humidity Membrane Program was begun in 2006 with the Florida Solar Energy Center (FSEC) as the lead organization. During the first three years of the program, FSEC was tasked with developing non-Nafion® proton exchange membranes with improved conductivity for fuel cells. Additionally, FSEC was responsible for developing protocols for the measurement of in-plane conductivity, providing conductivity measurements for the other funded teams, developing a method for through-plane conductivity and organizing and holding semiannual meetings of the High Temperature Membrane Working Group (HTMWG). The FSEC membrane research focused on the development of supported poly[perfluorosulfonic acid] (PFSA) – Teflon membranes and a hydrocarbon membrane, sulfonated poly(ether ether ketone). The fourth generation of the PFSA membrane (designated FSEC-4) came close to, but did not meet, the Go/No-Go milestone of 0.1 S/cm at 50% relative humidity at 120 °C. In-plane conductivity of membranes provided by the funded teams was measured and reported to the teams and DOE. Late in the third year of the program, DOE used this data and other factors to decide upon the teams to continue in the program. The teams that continued provided promising membranes to FSEC for development of membrane electrode assemblies (MEAs) that could be tested in an operating fuel cell. FSEC worked closely with each team to provide customized support. A logic flow chart was developed and discussed before MEA fabrication or any testing began. Of the five teams supported, by the end of the project, membranes from two of the teams were easily manufactured into MEAs and successfully characterized for performance. One of these teams exceeded performance targets, while the other requires further optimization. An additional team developed a membrane that shows great promise for significantly reducing membrane costs and increasing membrane lifetime.

Improving DOE-2's RESYS routine: User defined functions to provide more accurate part load energy use and humidity predictions  

SciTech Connect

In hourly energy simulations, it is important to properly predict the performance of air conditioning systems over a range of full and part load operating conditions. An important component of these calculations is to properly consider the performance of the cycling air conditioner and how it interacts with the building. This paper presents improved approaches to properly account for the part load performance of residential and light commercial air conditioning systems in DOE-2. First, more accurate correlations are given to predict the degradation of system efficiency at part load conditions. In addition, a user-defined function for RESYS is developed that provides improved predictions of air conditioner sensible and latent capacity at part load conditions. The user function also provides more accurate predictions of space humidity by adding ''lumped'' moisture capacitance into the calculations. The improved cooling coil model and the addition of moisture capacitance predicts humidity swings that are more representative of the performance observed in real buildings.

MAXIMUM HUMIDITY INDICATOR  

SciTech Connect

Moisture-sensitive systems to measure and indicate the maximum level of humidity exposure are discussed. A chemical indicator utilizing deliquescent salts and water-soluble dyes provides an irreversible color change at discrete levels of relative humidity. To provide indication of the time at which the exposure occurs, a circuit employing a resistive-type sensor was developed. A small, commercially available sensor is used in a portable probe to detect humidity leaks into controlled areas.

Humidity Control in Residences  

E-Print Network (OSTI)

Maintaining relative humidity below 60% for residential houses in humid climates promotes a healthy indoor environment. Yet, for such homes, these lower humidity levels are difficult to maintain with conventional recirculation air conditioning units. By introducing a separate vapor compression unit to pre-condition outside air, indoor relative humidity can be controlled. This new air conditioning system combines a ventilation unit with a conventional recirculation air conditioning unit. Although successful in maintaining indoor humidity levels below 60%, the new air conditioning system will require more electric energy to provide the additional dehumidification. However, this penalty is shown to be offset by reductions in sensible load during a summer week, which should result in lower energy consumption and peak electric demand during that period. The performance of this new air conditioning system is demonstrated using FSEC 3.0, a building energy simulation program developed by the Florida Solar Energy Center, to simulate the heat and moisture transport occurring within a prototypical residence located in Austin, Texas.

Active Humidity Control Through Gas-Fired Desiccant Humidity Pump  

E-Print Network (OSTI)

High equipment first cost and high operating costs, if electricity is used to drive such a system, have prohibited the application of active humidity control equipment in comfort conditioning in the past. Instead, passive techniques have been applied. A comparison of passive capacity control methods to control humidity shows that only the combined face and bypass and variable air volume system shows improved performance with respect to space humidity control, dew point depression, and response to perturbations. A gas-fired desiccant humidity pump will provide economical humidity control in existing and new construction using VAV or constant volume air distribution systems. The humidity pump is designed as a packaged make-up air module. It is coupled to new or existing conventional air-conditioning system via a duct. It consists of a triple integrated heat-exchanger combining (liquid) desiccant dehumidification with indirect evaporative cooling, a brine interchanger, and a gas-fired brine heater to regenerate the desiccant. Field experiments of two humidity pumps on existing commercial buildings have been initiated. Each system dehumidifies 5000 scfm of make-up air to meet all the latent loads, which is then fed to conventional, electric-driven HVAC equipment which meet all the sensible loads.

Air humidity requirements for human comfort  

SciTech Connect

Upper humidity limits for the comfort zone determined from two recently presented models for predicting discomfort due to skin humidity and insufficient respiratory cooling are proposed. The proposed limits are compared with the maximum permissible humidity level prescribed in existing standards for the thermal indoor environment. The skin humidity model predicts discomfort as a function of the relative humidity of the skin, which is determined by existing models for human heat and moisture transfer based on environmental parameters, clothing characteristics, and activity level. The respiratory model predicts discomfort as a function of the driving forces for heat loss from the respiratory tract, namely, the temperature and humidity of the surrounding air. An upper humidity limit based on a relative skin humidity of 0.54, corresponding to 20% dissatisfied, results in a maximum permissible humidity level near 100% RH. The requirements for respiratory comfort are much more stringent and result in lower permissible indoor air humidities. Compared with the upper humidity limit specified in existing thermal comfort standards, e.g., ASHRAE Addendum 55a, the humidity limit based on skin humidity was less restrictive and the humidity limit based on respiratory comfort was far more restrictive.

Automated flow-temperature-humidity control system  

SciTech Connect

An automated system that controls air flow, temperature, and humidity was developed from a commercially available temperature-humidity indicator and a specially built flow-temperature-humidity control module. Parameters are set using direct-reading dials on the control module. The air flow is maintained using a mass-flow controller while process controllers connected to the indicator regulate humidity and temperature. The system will run indefinitely without need for operator intervention. If the module and indicator are calibrated properly, accurate air flows (+-2% of full scale), temperatures (+-0.3/sup 0/C), and humidities (+-2% RH) can be achieved.

Development of a Humid Climate Definition

The role of humidity in indoor air quality has become of increasing concern in recent years. High indoor humidities can result in microbial growth on building surfaces, resulting in poor indoor air quality, as well as damage to the building and its contents. In addition to the IAQ impacts, high indoor humidity can cause occupant discomfort. The public review draft of ASHRAE Standard 62-1989R included requirements for installation of dehumidification controls in buildings with mechanical cooling located in humid climates. The draft standard included a definition of humid climate: where, during the warmest six consecutive months of a typical year, the wetbulb temperature is 19°C (67°F) or higher for 3500 hours or more, or 23°C (73°F) or higher for 1750 hours or more. This definition is that used in the 1993 ASHRAE Handbook of Fundamentals to define the humid climate region. The only areas in the continental United States which meet these criteria are close to the Gulf coast, all of Florida, and along the Atlantic coast as far north as southern North Carolina While it is clear that buildings in this humid climate region need to be carefully designed with regard to humidity control, it is also clear that buildings in other areas have an equal need for humidity control. The work described in this paper examines a number of potential indicators of "humid climate" and correlates them with the prevalence of indoor humidity problems in three building types. The FSEC 2.3 energy simulation computer program (Kerestecioglu et al. 1989) was used to simulate the three building types, using weather from 10 cities in the southeastern U.S. The FSEC software was selected because it is capable of accurately modeling moisture transfer within the building space and the dehumidification performance of cooling coils at part-load conditions, and predicting resulting humidity levels. The buildings modeled were a retail store (similar to a K-Mart or Wal-Mart), a large office building, and a fast food restaurant. Existing building models were employed for this study with ventilation rates in accordance with ASHRAE Standard 62-1989. The HVAC systems used were typical for these building types, without any special humidity control measures. The selected indicators of humidity problems are the number of hours per year with space humidity above 60% RH and the number of occupied hours with space humidity above 60% RH. TMY2 weather data (NREL 1995) for 10 cities was used for the annual building energy simulations. TMY2 data was also used to calculate a number of potential humid climate parameters for the same 10 cities. These included: the number of hours and the wetbulb-degree hours above 3 different wetbulb temperatures, the number of hours and grain-hours above 4 different humidity ratios, and the sensible, latent and total Ventilation Load Index (VLI). The VLI is the load (latent, sensible or total) generated by bringing one cfm of outdoor air to space neutral conditions over the course of one year (Hamman, et al. 1997). The ability of each climate parameter to predict indoor humidity problems was analyzed and compared. Implications of using the selected parameters to define a humid climate will be discussed

NEW ALUMINUM OXIDE HUMIDITY ELEMENT. Second Report  

SciTech Connect

An aluminum oxide humidity sensing element is discussed. These elements, which were developed primarily for use in radiosonde weather measuring equipmeni, have a fast response over the entire humidity range and through a broad temperature range of -80 deg F to +l35 deg F. The elements are a marked improvement over previous humidity sensing devices, and their use in specially designed testers allows measurements to be made which were previously unobtainable. Among their other desirable features, these elements are small and lightweight, can be made inexpensively of readily available materials, and can be mass produced. (auth)

Schools resolve IAQ/humidity problems with desiccant preconditioning  

Science Conference Proceedings (OSTI)

This article describes how desiccant-based total energy recovery systems were retrofitted to the mechanical systems at Willis Foreman Elementary and Spirit Creek Middle Schools to decouple the outdoor air latent load from the existing 3-ton packaged rooftop HVAC units. The resulting hybrid system maintains 50 to 52 percent relative humidity in the space while continuously providing 15 cfm per student of outdoor air to the facility (a three-fold increase of the original 5 cfm per student design) and does so in a very energy-efficient manner.

How factoring in humidity adds value  

SciTech Connect

Humidity plays a major role in health, comfort, and production. This article is a brief overview of the technologies available and a detailed explanation of how to calculate humidification loads. The problems caused by dry air vary from one building to another and from one area to another. But basically, there are three major problem types: static electricity, poor moisture stability, health and comfort problems. In today's business offices, static electricity can disrupt operations and increase operating costs. In printing facilities, low humidity causes poor ink registration. Also, sheets of paper stick together and jam machines, wasting time and paper. In computer rooms and data processing areas, dry air leads to static electric discharges that cause circuit board failure, dust buildup on heads, and storage tape breakage. Moisture stability impacts industrial processes and the materials they use. In many cases, product and material deterioration is directly related to moisture fluctuations and lack of humidity control. Books, antiques, paper, wood and wood products, and fruits and vegetables are a few items that can be ruined by low or changing humidity. The health impact of low humidity shows up in dry nasal and thread membranes, dry and itchy skin, and irritated eyes. For employees, this means greater susceptibility to colds and other viral infections. The results is higher absenteeism when humidity is low, which translates into lost productivity and profits.

Humidity effects on wire insulation breakdown strength.  

SciTech Connect

Methods for the testing of the dielectric breakdown strength of insulation on metal wires under variable humidity conditions were developed. Two methods, an ASTM method and the twisted pair method, were compared to determine if the twisted pair method could be used for determination of breakdown strength under variable humidity conditions. It was concluded that, although there were small differences in outcomes between the two testing methods, the non-standard method (twisted pair) would be appropriate to use for further testing of the effects of humidity on breakdown performance. The dielectric breakdown strength of 34G copper wire insulated with double layer Poly-Thermaleze/Polyamide-imide insulation was measured using the twisted pair method under a variety of relative humidity (RH) conditions and exposure times. Humidity at 50% RH and below was not found to affect the dielectric breakdown strength. At 80% RH the dielectric breakdown strength was significantly diminished. No effect for exposure time up to 140 hours was observed at 50 or 80%RH.

HUMID AIR TURBINE CYCLE TECHNOLOGY DEVELOPMENT PROGRAM  

SciTech Connect

The Humid Air Turbine (HAT) Cycle Technology Development Program focused on obtaining HAT cycle combustor technology that will be the foundation of future products. The work carried out under the auspices of the HAT Program built on the extensive low emissions stationary gas turbine work performed in the past by Pratt & Whitney (P&W). This Program is an integral part of technology base development within the Advanced Turbine Systems Program at the Department of Energy (DOE) and its experiments stretched over 5 years. The goal of the project was to fill in technological data gaps in the development of the HAT cycle and identify a combustor configuration that would efficiently burn high moisture, high-pressure gaseous fuels with low emissions. The major emphasis will be on the development of kinetic data, computer modeling, and evaluations of combustor configurations. The Program commenced during the 4th Quarter of 1996 and closed in the 4th Quarter of 2001. It teamed the National Energy Technology Laboratory (NETL) with P&W, the United Technologies Research Center (UTRC), and a subcontractor on-site at UTRC, kraftWork Systems Inc. The execution of the program started with bench-top experiments that were conducted at UTRC for extending kinetic mechanisms to HAT cycle temperature, pressure, and moisture conditions. The fundamental data generated in the bench-top experiments was incorporated into the analytical tools available at P&W to design the fuel injectors and combustors. The NETL then used the hardware to conduct combustion rig experiments to evaluate the performance of the combustion systems at elevated pressure and temperature conditions representative of the HAT cycle. The results were integrated into systems analysis done by kraftWork to verify that sufficient understanding of the technology had been achieved and that large-scale technological application and demonstration could be undertaken as follow-on activity. An optional program extended the experimental combustion evaluations to several specific technologies that can be used with HAT technology. After 5 years of extensive research and development, P&W is pleased to report that the HAT Technology Development Program goals have been achieved. With 0 to 10 percent steam addition, emissions achieved during this program featured less than 8 ppm NO{sub x}, less than 16 ppm CO, and unburned hydrocarbons corrected to 15 percent O{sub 2} for an FT8 engine operating between 0 and 120 F with 65 to 100 percent power at any day.

Lanthanide-halide based humidity indicators  

SciTech Connect

The present invention discloses a lanthanide-halide based humidity indicator and method of producing such indicator. The color of the present invention indicates the humidity of an atmosphere to which it is exposed. For example, impregnating an adsorbent support such as silica gel with an aqueous solution of the europium-containing reagent solution described herein, and dehydrating the support to dryness forms a substance with a yellow color. When this substance is exposed to a humid atmosphere the water vapor from the air is adsorbed into the coating on the pore surface of the silica gel. As the water content of the coating increases, the visual color of the coated silica gel changes from yellow to white. The color change is due to the water combining with the lanthanide-halide complex on the pores of the gel.

Exploring Maximum Humidity Control and Energy Conservation Opportunities with Single Duct Single Zone Air-Handling Units  

E-Print Network (OSTI)

Humidity control for single-duct single-zone (SDSZ) constant volume air handling units is known to be a challenge. The operation of these systems is governed by space temperature only. Under mild weather conditions, discharge air temperature can get much higher than the space dew point and the dehumidification capability of the system is diminished. Buildings served by this type of air handler often experience exceptionally high humidity levels under humid weather conditions. Many potential solutions and improvements exist. However, these solutions require system modifications or upgrades and therefore are less attractive to some facility owners. A Critical Humidity Control Program (CHCP) was developed to change the normal control sequence of the air-handling units during high humidity periods to help improve the moisture removal capability of the system. The program was not designed to solve the problem completely, but the overall humidity levels can be lowered and controlled within a reasonably low range (58% - 65%) for a significant part of the high humidity seasons. This approach is relatively easy to implement and does not require any hardware changes. This paper also summarizes various potential solutions to improve humidity control for SDSZ units. The advantages and disadvantages for each solution are compared.

Humidity, human factors, and the energy shortage  

SciTech Connect

Studies by the Institute for Environmental Research, Kansas State University, show that in terms of comfort, health, and performance, humidity control is an important element of environmental control and should not be eliminated for the sake of energy conservation. A constant level of comfort can be maintained if the humidity is increased and the temperature is decreased and vice versa; school absenteeism due to upper respiratory infection is related to classroom humidifcation; and psychomotor performance is better under warm, dry conditions than under warm, moist conditions. Humidification may be valuable in thermostat-setback programs by making cooler conditions comfortable.

Humidity fluctuations in solar greenhouse-residences  

SciTech Connect

The thermal performance of solar greenhouse-residences is well-documented. Data concerning temperature fluctuations and horticultural yield are obtainable and provide a clear picture of greenhouse-residence temperature extremes. However, both human comfort and plant growing environment are not dependent upon temperature alone. Air movement, radiation, and humidity are other criteria that can influence thermal comfort and growing conditions. The effect a vegetable peoducing greenhouse has on thermal comfort of an adjoining residence is illustrated in terms of temperature and humidity. An analysis of dewpoint conditions will further indicate the effect of moisture within the individual components. A solar greenhouse-residence with an integrated heating collection and distribution system exhibited higher internal humidities than conventional housing. The greenhouse exhibited greater diurnal swings than the adjoining residence. Transfer of moisture occurred from greenhouse to residence and caused infrequent dewpoint levels in the house. An analysis of two such buildings indicated a higher average relative humidity in the solar greenhouse-residence over conventional housing in the southeast.

Data Center Economizer Contamination and Humidity Study  

SciTech Connect

Data centers require continuous air conditioning to address high internal heat loads (heat release from equipment) and maintain indoor temperatures within recommended operating levels for computers. Air economizer cycles, which bring in large amounts of outside air to cool internal loads when weather conditions are favorable, could save cooling energy. There is reluctance from many data center owners to use this common cooling technique, however, due to fear of introducing pollutants and potential loss of humidity control. Concerns about equipment failure from airborne pollutants lead to specifying as little outside air as permissible for human occupants. To investigate contamination levels, particle monitoring was conducted at 8 data centers in Northern California. Particle counters were placed at 3 to 4 different locations within and outside of each data center evaluated in this study. Humidity was also monitored at many of the sites to determine how economizers affect humidity control. Results from this study indicate that economizers do increase the outdoor concentration in data centers, but this concentration, when averaged annually, is still below current particle concentration limits. Study results are summarized below: (1) The average particle concentrations measured at each location, both outside and at the servers, are shown in Table 1. Measurements show low particle concentrations at all data centers without economizers, regardless of outdoor particle concentrations. Particle concentrations were typically an order of magnitude below both outside particle concentrations and recently published ASHRAE standards. (2) Economizer use caused sharp increases in particle concentrations when the economizer vents were open. The particle concentration in the data centers, however, quickly dropped back to pre-economizer levels when the vents closed. Since economizers only allow outside air part of the time, the annual average concentrations still met the ASHRAE standards. However, concentration were still above the levels measured in data centers that do not use economizers (3) Current filtration in data centers is minimal (ASHRAE 40%) since most air is typically recycled. When using economizers, modest improvements in filtration (ASHRAE 85%) can reduce particle concentrations to nearly match the level found in data centers that do not use economizers. The extra cost associated with improve filters was not determined in this study. (4) Humidity was consistent and within the ASHRAE recommended levels for all data centers without economizers. Results show that, while slightly less steady, humidity in data centers with economizers can also be controlled within the ASHRAE recommended levels. However, this control of humidity reduces energy savings by limiting the hours the economizer vents are open. (5) The potential energy savings from economizer use has been measured in one data center. When economizers were active, mechanical cooling power dropped by approximately 30%. Annual savings at this center is estimated within the range of 60-80 MWh/year, representing approximately a 5% savings off the mechanical energy load of the data center. Incoming temperatures and humidity at this data center were conservative relative to the ASHRAE acceptable temperature and humidity ranges. Greater savings may be available if higher temperature humidity levels in the data center area were permitted. The average particle concentrations measured at each of the eight data center locations are shown in Table 1. The data centers ranged in size from approximately 5,000 ft{sup 2} to 20,000 ft{sup 2}. The indoor concentrations and humidity in Table 1 represents measurements taken at the server rack. Temperature measurements at the server rack consistently fell between 65-70 F. The Findings section contains a discussion of the individual findings from each center. Data centers currently operate under very low contamination levels. Economizers can be expected to increase the particle concentration in data centers, but the increase appears to still be

Evaluation of Humidity Control Options in Hot-Humid Climate Homes (Fact Sheet)  

DOE Green Energy (OSTI)

This technical highlight describes NREL research to analyze the indoor relative humidity in three home types in the hot-humid climate zone, and examine the impacts of various dehumidification equipment and controls. As the Building America program researches construction of homes that achieve greater source energy savings over typical mid-1990s construction, proper modeling of whole-house latent loads and operation of humidity control equipment has become a high priority. Long-term high relative humidity can cause health and durability problems in homes, particularly in a hot-humid climate. In this study, researchers at the National Renewable Energy Laboratory (NREL) used the latest EnergyPlus tool equipped with the moisture capacitance model to analyze the indoor relative humidity in three home types: a Building America high-performance home; a mid-1990s reference home; and a 2006 International Energy Conservation Code (IECC)-compliant home in hot-humid climate zones. They examined the impacts of various dehumidification equipment and controls on the high-performance home where the dehumidification equipment energy use can become a much larger portion of whole-house energy consumption. The research included a number of simulated cases: thermostat reset, A/C with energy recovery ventilator, heat exchanger assisted A/C, A/C with condenser reheat, A/C with desiccant wheel dehumidifier, A/C with DX dehumidifier, A/C with energy recovery ventilator, and DX dehumidifier. Space relative humidity, thermal comfort, and whole-house source energy consumption were compared for indoor relative humidity set points of 50%, 55%, and 60%. The study revealed why similar trends of high humidity were observed in all three homes regardless of energy efficiency, and why humidity problems are not necessarily unique in the high-performance home. Thermal comfort analysis indicated that occupants are unlikely to notice indoor humidity problems. The study confirmed that supplemental dehumidification is needed to maintain space relative humidity (RH) below 60% in a hot-humid climate home. Researchers also concluded that while all the active dehumidification options included in the study successfully controlled space relative humidity excursions, the increase in whole-house energy consumption was much more sensitive to the humidity set point than the chosen technology option. In the high-performance home, supplemental dehumidification equipment results in a significant source energy consumption penalty at 50% RH set point (12.6%-22.4%) compared to the consumption at 60% RH set point (1.5%-2.7%). At 50% and 55% RH set points, A/C with desiccant wheel dehumidifier and A/C with ERV and high-efficiency DX dehumidifier stand out as the two cases resulting in the smallest increase of source energy consumption. At an RH set point of 60%, all explicit dehumidification technologies result in similar insignificant increases in source energy consumption and thus are equally competitive.

Abstract Radiative Cooling in Hot Humid Climates  

E-Print Network (OSTI)

Passive radiative cooling of buildings has been an underachieving concept for decades. The few deployments have generally been in dry climates with low solar angles. The greatest need for cooling is in the tropics. The high humidity endemic to many of these regions severely limits the passive cooling available per radiative area. To wrest temperature relief from humid climates, not just nocturnal cooling but solar irradiance, both direct and indirect, must be addressed. This investigation explores the extent to which thermal radiation can be used to cool buildings in the tropics. It concludes that inexpensive materials could be fabricated into roof panels providing passive cooling day and night in tropical locations with an unobstructed view of sky.

Comprehensive field performance data are reported for a solar cabinet dryer under low humidity conditions of local harmattan season. The field data collected provide a frame of reference for similar data on dryer performance gathered under the normal local conditions of high relative humidity. The relative humidity, it is found, plays a most decisive role in the entire drying process.

Energy from humid air. Final report  

DOE Green Energy (OSTI)

Results to date are presented for a research project which is in progress at the South Dakota School of Mines and Technology. The goal of the research is to find a cost-effective process to convert the energy in humid air into mechanical work, which will be used to drive an electrical generator. The research is being carried out by computer modeling. Results for a natural draft tower show that it is not a cost-effective way to get energy from humid air. Parametric studies are presented for expansion-compression cycles. With suitable conditions, including large amounts of cooling during compression, this cycle has an attractive net work output. To avoid using all the output power to overcome machine losses, it appears necessary to use a one-machine mechanization. The most promising uses vortex flow to achieve the necessary expansion and subsequent compression with cooling. Power output and costs have been estimated for a vortex plant located in Puerto Rico.

Roots of Mold Problems and Humidity Control Measures in Institutional Buildings with Pre-Existing Mold Condition  

E-Print Network (OSTI)

Humidity control and mold in buildings has become an increasingly important problem. Once a building has experience mold growth on walls, ceilings, and other surfaces, it does not take longterm exposure to moisture for mold to re-grow in the building. Some commercial buildings on the Texas A&M University (TAMU) campus have suffered with humidity problems for many years. The Continuous Commissioning (CCSM) group of the Energy Systems Lab in collaboration with the Utilities Office of Energy Management, and the TAMU Physical Plant, was dispatched to perform Continuous Commissioning on these commercial buildings in order to find viable solutions to the humidity problem. The CC group performed extensive field tests and analysis on building air handling unit (AHU), exhaust systems, building construction, and the Energy Management Control System (EMCS). Based on the field studies and analysis, a four-category (Design, construction, building retrofits and alterations, and poor maintenance) system was set up to classify sources for high humidity problems. This paper presents the investigation and follow-up efforts, which identified reasons and corrective measures for the high humidity levels in these buildings, turning these inefficient and humid commercial buildings into comfortable environments. Recommendations for dealing with such possible problems are provided.

Indirect health effects of relative humidity in indoor environments  

SciTech Connect

A review of the health effects of relative humidity in indoor environments suggests that relative humidity can affect the incidence of respiratory infections and allergies. Experimental studies on airborne-transmitted infectious bacteria and viruses have shown that the survival or infectivity of these organisms is minimized by exposure to relative humidities between 40 and 70%. Nine epidemiological studies examined the relationship between the number of respiratory infections or absenteeism and the relative humidity of the office, residence, or school. The incidence of absenteeism or respiratory infections was found to be lower among people working or living in environments with mid-range versus low or high relative humidities. The indoor size of allergenic mite and fungal populations is directly dependent upon the relative humidity. Mite populations are minimized when the relative humidity is below 50% and reach a maximum size at 80% relative humidity. Most species of fungi cannot grow unless the relative humidity exceeds 60%. Relative humidity also affects the rate of offgassing of formaldehyde from indoor building materials, the rate of formation of acids and salts from sulfur and nitrogen dioxide, and the rate of formation of ozone. The influence of relative humidity on the abundance of allergens, pathogens, and noxious chemicals suggests that indoor relative humidity levels should be considered as a factor of indoor air quality. The majority of adverse health effects caused by relative humidity would be minimized by maintaining indoor levels between 40 and 60%. This would require humidification during winter in areas with cold winter climates. Humidification should preferably use evaporative or steam humidifiers, as cool mist humidifiers can disseminate aerosols contaminated with allergens.

Humidity in Attics -- Sources and Control Methods  

Science Conference Proceedings (OSTI)

Guidelines for the control of moisture in attics are in a state of flux. The 1981 ASHRAE Handbook of Fundamentals gives only ''Past Practice'', and notes that such practice might not be currently valid. Furthermore, in the past it was assumed that the attic was an inert structure on which moisture would either condense or pass through unaffected. Results are presented which show that the attic is in a constant state of flux, absorbing and releasing moisture. A mathematical model for predicting the moisture content of attic wood members is presented. The model is used to predict hour-by-hour attic air humidity ratio, and seasonal wood moisture content. Results are compared with measured data. The application of the model to the re-calculation of attic ventilation standards is discussed, both with respect to condensation and wood rot.

RELATIVE HUMIDITY TESTS IN SUPPORT OF THE 3013 STORAGE AND SURVEILLANCE PROGRAM  

SciTech Connect

Techniques to control the initial relative humidity over oxide/salt mixtures have been developed using cerium oxide as a surrogate for plutonium oxide. Such control is required to validate certain assumptions in the Department of Energy Standard DOE-STD-3013, and to provide essential information to support field surveillance at the storage sites for excess plutonium oxides. Concern over the validity of the assumption that corrosion induced degradation in 3013 containers could be controlled by assuring that the moisture content of any stored oxide/salt mixture was below 0.5 w t% arose when stress corrosion cracks were found in test samples exposed at room temperature to plutonium oxide/salt mixtures having a moisture content only marginally above 0.5 wt %. Additionally, analysis of the stress corrosion cracking observations suggests that the initial relative humidity over the oxide/salt mixture may play a major role in the cracking process. The investigations summarized in this report provide the procedures necessary to control the initial relative humidity to selected values within the range of 16 to 50% by controlling the loading relative humidity (18 to 60%) and the oxide/salt mixture water content (0.05 to 0.45 wt %). The studies also demonstrated that the initial relative humidity may be estimated by calculations using software EQ3/6. Cerium oxide/salt mixtures were used in this study because qualification tests with non-radioactive materials will reduce costs while increasing the breadth of the test programs required to support field surveillances of stored 3013 containers.

AIR ALPHA PROPORTIONAL COUNTER INSENSITIVE TO ATMOSPHERIC HUMIDITY  

SciTech Connect

A conventional alpha proportional counter which uses air as the counter gas is sensitive to high relative humidity and generates spurious pulses that cannot be distinguished from actual alpha pulses. It was found possible to operate such a counter satisfactorily at high relative humidity by passing a small current ( approximates 15 ma) through the center wire. In this manner the center wire is heated and the relative humidity of the surrounding sheath of air is reduced sufficiently so that operation of the counter at high relative humidity is comparable to operation with dry air, Two different mechanisms are proposed for the formation of spurious pulses in such a counter at high relative humidity.

Transparent Humidity Sensor Using Cross-Linked Polyelectrolyte Membrane  

Science Conference Proceedings (OSTI)

This paper describes the fabrication of a porous cross-linked polyelectrolyte membrane and the characterization of its humidity sensitivity performance. Electrostatic self-assembly, combined with acid treatment, and post-deposition annealing produced the membrane. The fabrication process offers the ability to control the thickness of the membrane, as well as enabling the engineering of the humidity sensitivity properties. A transparent humidity sensor was fabricated by integrating the membrane between two parallel electrodes. In order to improve the moisture absorption and diffusion, both the polyelectrolyte layer and the electrode were made porous. The membrane was cross-linked to enhance the durability in high humid environments. Such a polyelectrolyte membrane showed high sensitivity to relative humidity variation over a range of 25%–99%. The see-through property of the structure adds extra features and benefits to the sensor.

Humidity-temperature relationships in the tropical troposphere  

SciTech Connect

Based on the observed interannual variations of water vapor and temperature over the past 26 years the authors have examined the relationship between the variations of water vapor and temperature in the tropical troposphere. In both the lower and upper troposphere, tropical mean specific humidity increases with temperature. The rate of fractional increase of specific humidity with temperature at 500 mb is as large as that in the surface boundary layer. However, the rate of fractional increase of specific humidity with temperature is significantly smaller than that given by a model with a fixed relative humidity, particularly in the region immediately above the tropical convective boundary layer. The variations of tropical mean relative humidity show consistently a negative correlation with the temperature variations. The authors have further compared the spatial structure of the specific humidity variations with that of the temperature variations. Though the vertical structure of tropical mean specific humidity has more variability than that of the tropical mean temperature, the leading EOF for the normalized specific humidity variations is almost exactly the same as the leading EOF for the normalized temperature variations. The characteristic horizontal structure of the specific humidity variations at levels in the free troposphere, however, is very different from that of the temperature variations. The leading EOF for the normalized specific humidty variations at levels in the free troposphere is characterized by regions with alternating positive and negative signs, while the leading EOF for the corresponding temperature variations has a single sign throughout the Tropics. When the variations are averaged zonally, the leading EOF for the normalized specific humidity variations still differs significantly from that of the normalized temperature variations, but the leading EOF has the same sign from the deep Tropics to the subtropics. 31 refs., 15 figs., 1 tab.

Effects of humidity during photoprocessing on thin film metallization adhesion  

SciTech Connect

Humidity effects during photoprocessing on tantalum/chromium/gold thin film networks (TFNs) were investigated. Humidity conditions at various process steps were controlled by placing either desiccant or water in handling containers for the TFNs. The TFNs photoprocessed in humid conditions had a much higher occurrence of metallization failures compared to TFNs processed in dry conditions. Ceramic surface defects were shown to cause pores in the thin films, and these pores enhanced corrosion susceptibility for the films. This study resulted in a desiccated storage process for production of TFNs.

Dynamics of electrostatically driven granular media: Effects of humidity  

SciTech Connect

We performed experimental studies of the effect of humidity on the dynamics of electrostatically driven granular materials. Both conducting and dielectric particles undergo a phase transition from an immobile state (granular solid) to a fluidized state (granular gas) with increasing applied field. Spontaneous precipitation of solid clusters from the gas phase occurs as the external driving is decreased. The clustering dynamics in conducting particles is primarily controlled by screening of the electric field but is aided by cohesion due to humidity. It is shown that humidity effects dominate the clustering process with dielectric particles.

Humidity effects on calibrations of radiation therapy electrometers  

SciTech Connect

Purpose: To eliminate variation in electrometer calibration results caused by high humidity and suboptimal connectors on the standard capacitors and to implement hardware that prevents overloading of the input stage of electrometers during calibration. Methods: A humidity-controlled cabinet was installed to provide a low-humidity environment for the standard capacitors. All of the coaxial BNC connections were replaced with Triax (TRB) connectors with the exception of the output from the voltage source. A three-stage RC filter with cascaded RC low-pass sections was designed and tested. Results: The installation of the humidity cabinet resulted in a major improvement in the stability and reproducibility of the electrometer calibration system. For the three years since this upgrade, the Ionizing Radiation Standards (IRS) electrometer calibration results have been consistent regardless of the ambient relative humidity in the lab. The connector replacements improved grounding in the calibration circuit. The three-stage filter allows the voltage at the output to rise in an S-shaped waveform, resulting in a smooth rise of the current through the isolation resistor from zero and back again, with no abrupt transition. For the filter design chosen, 99.99% of the charge is delivered within 6 s. Conclusions: A three-way improvement to the calibration measurement system was successful in eliminating the observed variations, resulting in an electrometer calibration measurement system that is unaffected by humidity and allowing reliable year-round calibrations of any electrometer encountered since the implementation of these changes.

Humidity Dependence of Adhesion for Silane Coated Microcantilevers  

SciTech Connect

This study examines adhesion between silane-coated micromachined surfaces that are exposed to humid conditions. Our quantitative values for interfacial adhesion energies are determined from an in-situ optical measurement of deformations in partly-adhered cantilever beams. We coated micromachined cantilevers with either ODTS (C{sub 18}H{sub 37}SiCl{sub 3}) or FDTS (C{sub 8}F{sub 17}C{sub 2}H{sub 4}SiCl{sub 3}) with the objective of creating hydrophobic surfaces whose adhesion would be independent of humidity. In both cases, the adhesion energy is significantly lower than for uncoated, hydrophilic surfaces. For relative humidities (RH) less than 95% (ODTS) and 80% (FDTS) the adhesion energy was extremely low and constant. In fact, ODTS-coated beams exposed to saturated humidity conditions and long (48 hour) exposures showed only a factor of two increase in adhesion energy. Surprisingly, FDTS coated beams, which initially have a higher contact angle (115{degree}) with water than do ODTS coated beams (112{degree}), proved to be much more sensitive to humidity. The FDTS coated surfaces showed a factor of one hundred increase in adhesion energy after a seven hour exposure to 90% RH. Atomic force microscopy revealed agglomerated coating material after exposed to high RH, suggesting a redistribution of the monolayer film. This agglomeration was more prominent for FDTS than ODTS. These findings suggest a new mechanism for uptake of moisture under high humidity conditions. At high humidities, the silane coatings can reconfigure from a surface to a bulk phase leaving behind locally hydrophilic sites which increase the average measured adhesion energy. In order for the adhesion increase to be observed, a significant fraction of the monolayer must be converted from the surface to the bulk phase.

Evaluation of Energy Efficiency Measures in Hot and Humid Climates  

E-Print Network (OSTI)

Hot and humid climates present some of the most complex challenges for sustainable building designs. High temperatures coupled with high humidity create extreme comfort problems and exacerbate the potential for condensation, mold and mildew. These are usually remedied with conventional mechanical air conditioning systems, but the move toward sustainability urges designers to find less energy intensive solutions. An integrated design process coupled with energy modeling and lifecycle analysis can unite design teams around desired outcomes to provide an optimized design solution for projects in these climates. Such an approach involves first minimizing building loads and then reducing residual energy consumed by the HVAC systems. This paper presents an integrated design approach to evaluating the most efficient energy measures in hot and humid climates and summarizes the findings of a series of cases using this approach, including international examples of office, education, and small retail buildings in ASHRAE Climate Zones 1A and 2A.

Relative humidity in the near-field environment  

SciTech Connect

The Yucca Mountain Site Characterization Project is investigating Yucca Mountain, Nevada, for its suitability as a potential repository for high-level nuclear wastes. United States federal regulation 10CFR60 requires that radioactive nuclides be substantially contained in waste packages for 300 to 1000 years after the emplacement. To meet the regulation, a waste package container should remain intact for several hundreds of years. It has been shown that high humidity increases the corrosion potential of metallic container materials. Relative humidity as a function of water saturation in intact rock is measured. The results of this test can be used to calibrate the relative humidity in the near-field environment predicted by model calculations using thermal-hydrological codes such as VTOUGH. This is a report on the progress of that experiment.

Atmospheric Condensation Potential of Windows in Hot, Humid Climates  

E-Print Network (OSTI)

In hot, humid climates, the internal surfaces of windows in air-conditioned buildings are in contact with relatively colder air. Meanwhile, the external surfaces are exposed to hot humid atmospheric air. This hygro-thermal condition may cause frequent atmospheric condensation on external surfaces of windows when their surface temperature drops below the dew point temperature of the hot humid air. To date, external surface condensation on windows has been given relatively much less importance than their internal surface condensation. In addition, the thermal analysis of windows in hot humid climates has always been performed in the absence of condensation. Under moderate air temperature and humidity conditions, such practice is acceplable. However, when windows experience atmospheric condensation on their external surfaces, the effect of condensation on window energy loss needs to be examined. In this paper, the external condensation process is analyzed and the atmospheric water vapor mass condensation rate has been obtained by utilizing a simplified transient uni-dimensional finite difference model. The results show that this model has enhanced the assessment of the potential for atmospheric condensation on windows in hot, humid climates and in predicting the amount of condensation expected, as well as the associated energy loss for given thermal and moisture conditions. The numerical computation of the model is able to account for condensation and its impact on the temperature gradient across the window. Thermal analysis of both single and insulated double-glazed windows under condensation conditions is presented. The work also includes the computational procedure used and the results or a case study demonstrating the model's capabilities.

Residential Humidity Control: Exciting New Opportunities with Air Flow Modulation  

E-Print Network (OSTI)

This paper reviews psychrometric principles and shows how to formulate a psychrometric chart from a single equation. The chart is used to demonstrate the manner in which a conventional single-speed air conditioner adjusts its operating point in an attempt to control humidity over a range of conditions. The system performance with an electronically commutated motor (ECM) driving the blower is then presented. With ECM blower speed control, it is possible to raise the sensible capacity, reduce the sensible capacity, and boost the efficiency of an otherwise conventional air conditioner. This makes such systems ideal to respond to the changing loads in a hot and humid climate.

The temperature, humidity, wind, and pressure system (THWAPS) provide surface reference values of these measurements for balloon-borne sounding system (SONDE) launches. The THWAPS is located adjacent to the SONDE launch site at the Southern Great Plains (SGP) Central Facility. The THWAPS system is a combination of calibration-quality instruments intended to provide accurate measurements of meteorological conditions near the surface. Although the primary use of the system is to provide accurate surface reference values of temperature, pressure, relative humidity (RH), and wind velocity for comparison with radiosonde readings, the system includes a data logger to record time series of the measured variables.

Humidity response of the Eberline model PAC-7 alpha instrument  

SciTech Connect

Response of the Eberline Model PAC-7 alpha instrument under varying relative humidity (RH) and temperature conditions was studied in an environmental chamber. Electric discharges resulting in spurious counts or in instrument paralysis occurred at 35 to 50% RH. Improvement in the RH level tolerated by the PAC-7 alpha instrument was obtained by conformal coating of the high-voltage region of the printed circuit (PC) board. Following this treatment, electric discharges occurred only at relatively high humidity levels and then as a result of high-voltage breakdown within the AC-24C probe rather than within the PC board.

An analysis of maximum residential energy-efficiency in hot and humid climates  

E-Print Network (OSTI)

Energy-efficient building design involves minimizing the energy use and optimizing the performance of individual systems and components of the building. The benefits of energyefficient design, in the residential sector, are direct and tangible, provided that design strategies with a substantial combined energy and cost-saving potential are adopted. Many studies have been performed to evaluate the energy-saving potential and the costeffectiveness of various design options, and to identify conditions for optimizing the performance of building systems and components. The results of these studies, published in various resources, were analyzed discretely using different techniques, and were reported using different bases for comparison. Considering the complex interaction of, and energy flows through various building components, it is difficult to directly compare/combine the results from various studies to determine the energy-saving potential of combination of strategies, and to select an appropriate set of strategies for making design decisions. Therefore, this thesis develops a comprehensive survey and analysis of energy-efficient design strategies and their energy-saving potential, in isolation as well as in combination, using a DOE-2 simulation model of a prototype house in the hot and humid climate of Houston, Texas. Optimized strategies that included building configuration, materials/ assembly for building envelop components, and efficient mechanical and electrical systems, equipment and appliances, were applied in combination that could minimize the annual energy use. Application of these strategies is expected to allow downsizing systems and equipment and to confirm their operation at their rated performance, resulting in additional installation and operation cost savings. The study is concluded by outlining the procedures for selecting optimized set of strategies, and by developing guidelines for achieving maximum energy-efficiency in singlefamily detached houses in hot and humid climates. Thus, this study will facilitate the selection of energy-saving measures for their individual or combined application for developing energyefficient residences in hot and humid climates.

The Temperature and Relative Humidity Control in Cushing Library  

E-Print Network (OSTI)

Cushing Library located on TAMU campus is a special building, which needs precise temperature and relative humidity control, because it stores a number of rare collections and memorial books. There are five air-handling units (AHUs) serving the building. This paper will concentrate the unit, which serves the book stacks. This AHU is a multiple zone, constant air volume (MZCAV) system, with reheat and direct digital control (DDC). It has a standard cooling coil, glycol cooling coil, steam humidifier, and heat recovery. The chilled water to the standard cooling coil is served by the chilled water loop on the campus. There is a glycol chiller for the glycol cooling coil for added dehumidification ability. Because of programming problems and hardware problems, the relative humidity was not controlling properly. In this paper, the new control program for temperature and relative humidity control is implemented and the energy savings from the new control program is estimated. The temperature and relative humidity are now under control.

Appropriate Conservation Measures for Single-Family Buildings in Hot, Humid Climates  

E-Print Network (OSTI)

The effectiveness of a number of energy conservation measures for homes located in hot, humid climates was analyzed using the DOE-2.1B building simulation model. Measures having the greatest benefits to the homeowner are predicted to be the addition of ceiling insulation only if the house is not already insulated, weatherization, and reduction of the wall outer surface solar absorptance. The weatherization and solar absorptance reduction measures should be do-it-yourself installations to be cost-effective Replacement of an air-conditioning unit with a new high-efficiency unit was very effective in reducing peak demand and annual cooling energy. Unless the energy efficiency ratio of the existing unit is low (< 6), replacement is generally not cost-effective. The measures were predicted to result in slightly increased indoor humidities, but their effect on human comfort was predicted to be small. However, this conclusion should be considered preliminary since the simulation models used for these predictions have limitations. The amount of energy that can be saved by these measures is very dependent on the occupant's lifestyle, such as the degree to which the occupants will alter clothing to achieve comfort.

Instrument uncertainty effect on calculation of absolute humidity using dewpoint, wet-bulb, and relative humidity sensors  

SciTech Connect

As part of the US Department of Energy`s Advanced Desiccant Technology Program, the National Renewable Energy Laboratory (NREL) is characterizing the state-of-the-art in desiccant dehumidifiers, the key component of desiccant cooling systems. The experimental data will provide industry and end users with independent performance evaluation and help researchers assess the energy savings potential of the technology. Accurate determination of humidity ratio is critical to this work and an understanding of the capabilities of the available instrumentation is central to its proper application. This paper compares the minimum theoretical random error in humidity ratio calculation for three common measurement methods to give a sense of the relative maximum accuracy possible for each method assuming systematic errors can be made negligible. A series of experiments conducted also illustrate the capabilities of relative humidity sensors as compared to dewpoint sensors in measuring the grain depression of desiccant dehumidifiers. These tests support the results of the uncertainty analysis. At generally available instrument accuracies, uncertainty in calculated humidity ratio for dewpoint sensors is determined to be constant at approximately 2%. Wet-bulb sensors range between 2% and 6% above 10 g/kg (4%--15% below), and relative humidity sensors vary between 4% above 90% rh and 15% at 20% rh. Below 20% rh, uncertainty for rh sensors increases dramatically. Highest currently attainable accuracies bring dewpoint instruments down to 1% uncertainty, wet bulb to a range of 1%--3% above 10 g/kg (1.5%--8% below), and rh sensors between 1% and 5%.

Why alite stops hydrating below 80% relative humidity  

Science Conference Proceedings (OSTI)

It has been observed that the hydration of cement paste stops when the relative humidity drops below about 80%. A thermodynamic analysis shows that the capillary pressure exerted at that RH shifts the solubility of tricalcium silicate, so that it is in equilibrium with water. This is a reflection of the chemical shrinkage in this system: according to Le Chatelier's principle, since the volume of the products is less than that of the reactants, a negative (capillary) pressure opposes the reaction.

Case Study: Sick Building Syndrome in a Humid Climate  

E-Print Network (OSTI)

An indepth environmental investigation was conducted at a four-story building officing 1200 employees in Oklahoma. A preassessment and walkthrough of the facility revealed extensive ongoing renovations throughout the building. Renovations consisted of installations of new partitions, carpeting, ceiling tiles, and repainting. Management was receiving numerous complaints related to the indoor air quality from all parts of the building, particularly the unrenovated areas. The majority of employee complaints originated from the unrenovated second floor; in contrast, few complaints had been submitted from the finished fourth floor area. Due to the disparity in employee complaints from these two floors, the investigation focused on a comparison of the air quality on the second and fourth floors. The initial walkthrough revealed inordinate amounts of dust in the occupied space of the second floor. High humidity levels were measured throughout the building. Other potential problems -- i.e., poor lighting, job stress, poor air circulation, stuffy air, thermal discomfort. smokers in the area --were also noted at this point. Questionnaires were made available to occupants on both floors to attain a better understanding of employee problems and assist in formulating an investigation plan. Collectively the nonspecificity of the responses tended to indicate building-related problems often described by the term ''Sick Building Syndrome" (SBS). Based on the questionnaire responses, the walkthrough observations, and the lack of specific illnesses, the investigation focused on identification of and testing for sources of chemical and particulate emissions and possible inadequacies of the mechanical ventilation system in providing the necessary amount of outside air. Although the building investigation revealed few signs of biological contamination, problems of this nature are not uncommon in climates with high humidity. The potential for biological proliferation in buildings with excessive humidity are discussed in the paper. The SBS causation was multifactorial and thus could not be attributed to a single etiologic factor. Temperature and humidity problems were partially attributed to the inadequate provision of chilled water (at a low enough temperature) to ensure proper tempering and dehumidification of the supply air. These periodic excursions in temperature and relative humidity were compounded by an associated reduction in outside air which exacerbated the situation. Other recommendations had to do with improving the filtration system, balancing of the air handling system, improving the ventilation efficiency, separation of smokers and nonsmokers, and the infusion of a fastidious cleaning and maintenance program combined with an adequate supply of fresh air per ASHRAE 62-89 specifications.

RELATIVE HUMIDITY, INOSITOL AND THE EFFECT OF RADIATIONS ON AIR-DRIED MICROORGANISMS  

SciTech Connect

Investigations were made on the effects of uv irradiation on E. coli and Pseudomonas aeroginosa and x irradiation on Serratia marcescens and on the influence of relative humidity and inositol on these effects. The effect of relative humidity was the same for all organisms tested. Under the experimental conditions used, little or no uv irradiation damage occurred above 70% relative humidity, nor were there many deaths occurring in unirradiated aerosols. At about 65% there was a rapid change in the sensitivity to both uv and drying alone, with the maximum rate of change taking place between 65 and 55% relative humidity for uv, and 65 and 45% relative humidity for non-irradiated cells. Some organisms showed an equally sharp increase in sensitivity to drying in the dark between 65 and 55% relative humidity. With uv irradiation relative humidity changes below 55% had little or no effect on the death rate and the same was true for non-irradiated cells below 45% relative humidity. Under all experimental conditions, with the possible exception of a relative humidity region around 40%, inositol completely prevented inactivation of the cells or viruses in the dark or under uv irradiation. Under x irradiation the cells were more stable at relative humidity values below 50% than at higher values, and once again the region in which a pronounced change occurred was between 50 and 70% relative humidity.

Development and analysis of a sustainable, low energy house in a hot and humid climate  

E-Print Network (OSTI)

This study examines the lifetime building energy consumption of a typical house in Bangkok, Thailand. The lifetime building energy consumption is composed of three major components: 1) the energy used during building construction (embodied energy), 2) the energy used in building operation (annual energy), and 3) the energy used during building demolition (demolition energy). For the embodied energy and the energy used during building demolition analyses, the reference data from reliable sources both in the U.S. and the UK were compared. For the annual energy analysis, the DOE-2 computer energy simulation program was the major analysis tool. The annual energy use of different materials and design strategies were compared based on the DOE-2 simulations. The best energy performances from each comparison were selected to design a new energy efficient house. The results from all three components were combined and compared to a typical American house. Finally, design guidelines for sustainable low energy houses in hot and humid climates were developed.

Small Residence Multizone Modeling with Partial Conditioning for Energy Effieiency in Hot and Humid Climates  

E-Print Network (OSTI)

The purpose of this study is to reduce the energy cost of the low-income households in the hot and humid climates of the U.S. and thereby to help them afford comfortable homes. In this perspective, a new HVAC energy saving strategy, i.e. “partial conditioning” was modeled and its potential to reduce the HVAC energy consumption of the low income homes in Texas was quantified. The “partial conditioning” strategy combined three primary ideas: 1) using historic courtyard building schemes to provide a buffer zone between conditioned spaces, 2) zoning and applying occupancy based heating/cooling in each zone, and 3) reusing the conditioned air returning from the occupied zones in the unoccupied zones before it is returned to the system. The study was conducted in four steps: 1) data collection, 2) baseline design and modeling, 3) partial conditioning design and modeling, and 4) analyses and recommendations. First, a site visit was held to the Habitat for Humanity office in Bryan, Texas to collect data on the characteristics of the Habitat for Humanity houses built in Bryan. Second, a base-line Habitat for Humanity house was designed and modeled based on this information along with multiple other resources including International Energy Conservation Code 2012 and Building America benchmark definitions. A detailed comparison was made between the commonly used energy modeling tools (DOE-2.1e, EnergyPlus and TRNSYS) and a modeling method was developed for the estimation of the baseline energy consumption. Third, the “partial conditioning” strategy was introduced into the baseline energy model to simulate a partially conditioned atrium house. As the occupied zone and the direction of the airflow changed throughout the year in the partially conditioned house, this step required an innovative air loop model with interzonal air ducts that allowed for sched- uled bi-directional airflow. This air loop was modeled with the AirflowNetwork model of EnergyPlus. Fourth, the modeling results were analyzed and discussed to determine the performance of the partial conditioning strategy in a hot and humid climate. It was found that partial conditioning strategy can provide substantial (37%-46%) reduction in the overall HVAC energy consumption of small residences (?1,000 ft2) in hot and humid climates while performing better in meeting the temperature set points in each room. It was also found that the quantity of the energy savings that can be obtained with the partial conditioning strategy depends significantly on the ground coupling condition of the house for low rise residential buildings.

Response of bean and tobacco to ozone: effect of light intensity, temperature and relative humidity  

SciTech Connect

Pinto bean (Phaseolus vulgaris, L.) and Bel W/sub 3/ tobacco (Nicotiana tabacum, L.) were grown and exposed to 40 pphm ozone for 1 hr under a range of light intensities, temperatures, and relative humidities. Foliar injury to the more sensitive plant leaves was determined on the third day after exposure. Each atmospheric factor was independently assessed. Two significant three-way interactions were found: exposure light intensity by growth light intensity by species, and growth temperature by exposure temperarture by species. Three significant two-way interactions were found for humidity: growth humidity by exposure humidity, growth humidity by species, and exposure humidity by species. The sensitivity of each species to ozone changed with changes in each environmental condition.

A simple distribution method for two-dimensional temperature/humidity bin data  

SciTech Connect

A distribution model is developed for relative humidity, and additional relationships are presented that allow the distribution model to be used on an hourly basis with either monthly-average daily relative humidity or monthly-average daily dry-bulb temperature and clearness index as the only meteorological data input. A procedure is described that allows the estimation of two-dimensional dry-bulb temperature/humidity ratio bin data from the distribution models for dry-bulb temperature and relative humidity. Comparisons of measured and estimated dry-bulb temperature/humidity ratio bin data are presented. A design method for the cooling load on a residential air conditioner is described, and air conditioning loads are calculated using both measured and estimated dry-bulb temperature/humidity ratio bin data.

Effects of Temperature and Humidity on Wilethane 44 Cure  

SciTech Connect

Wilethane 44 is a polyurethane adhesive developed by the Materials Team within ESA-MEE at Los Alamos National Laboratory as a replacement for Hexcel Corporation Urethane 7200. Urethane 7200 is used in numerous weapon systems, but it was withdrawn from the market in 1989. The weapons complex requires a replacement material for use in the W76-1 LEP and the W88, as well as for assembly of JTAs for other warheads. All polyurethane systems are susceptible to moisture reacting with unreacted isocyanate groups. This side reaction competes with the curing reaction and results in CO{sub 2} formation. Therefore, a polyurethane adhesive can exhibit foaming if appropriate environmental controls are not in place while it cures. A designed experiment has been conducted at TA-16-304 to determine the effects of ambient conditions on the properties of cured Wilethane 44. Temperature was varied from 15 C to 30 C and relative humidity from 15% to 40%. The density, hardness at 24 hours, and butt tensile strength on aluminum substrates were measured and fitted to quadratic equations over the experimental space. Additionally, the loss and storage moduli during cure were monitored as a function of cure temperature. These experiments provide a stronger basis for establishing appropriate environmental conditions and cure times when using Wilethane 44. The current guidelines are a working time of 90 minutes, a cure time of 18 hours, and a relative humidity of less than 25%, regardless of ambient temperature. Viscosity measurements revealed that the working time is a strong function of temperature and can be as long as 130 minutes at 15 C or as short as 90 minutes at 30 C. The experiments also showed that the gel time is much longer than originally thought, as long as 13 hours at 15 C. Consequently, it may be necessary to extend the required cure time at temperatures below 20 C. Allowable humidity varies as a function of temperature from 34% at 15 C to 15% at 30 C.

AMT-4 RADISONDE TRANSMITTER MODIFICATION ASSEMBLY (USING THE NEW ALUMINUM- OXIDE HUMIDITY ELEMENT)  

SciTech Connect

A modification to the AMT-4 radiosonde transmitter and modulator which permits the use of a new aluminum oxide humidity element is described. The modification is simple enough to be made by relatively unskilled personnel in the field and involves: using the newly developed aluminum oxide humidity element, slightly modifying the transmitter, and slightly revising the modulator circuitry. The polarization problem usually associated with using humidity elements in a direct-current circuit is also minimized by this modification. (auth)

NEWTON: Why Does It Rain  

NLE Websites -- All DOE Office Websites (Extended Search)

Why Does It Rain? Why Does It Rain? Name: Drama Status: student Grade: K-3 Location: FL Country: USA Date: Fall 2011 Question: Why does it rain? Replies: Drama, When water is heated it evaporates into the air. You cannot see the water in the air, but sometimes you can feel it (especially when it is hot outside). Have you ever noticed that on some warm days it is really humid (sticky and sweaty) and other warm days it feels dry? You might have also noticed that in the morning, when the air is cool, you might find dew or mist on the leaves and grass. This occurs because cold air cannot hold much of moisture. There is a limit to the amount of water that air can hold. This limit is known as the saturation limit (or dew point). When the air is completely saturated and cannot hold any more water, then it comes down as rain (and leaves all that heat in the air).

Influence of glazing selection on commercial building energy performance in hot and humid climates  

SciTech Connect

This paper presents a comparative study in which commercial building perimeter zone electric energy (cooling, lighting, fan) and peak electric demand are analyzed as a function of window glazing type, with a particular emphasis on the use of glazings with wavelength-selective solar-optical properties. The DOE-2 energy analysis simulation program was used to generate a data base of the electric energy requirements of a prototypical office building module located in Singapore. Algebraic expressions derived by multiple regression techniques permitted a direct comparison of those parameters that characterize window performance in hot and humid climates: orientation, size, and solar-optical properties. Also investigated were the effects of exterior and interior shading devices, as well as interior illuminance level, power density, and lighting controls to permit the use of daylighting. These regression equations were used to compare the energy implications of conventional window designs and newer designs in which the type of coating and substrate were varied. The analysis shows the potential for substantial savings through combined solar load control and lighting energy use reduction with daylighting.

ANALYSIS OF OFF-GRID, OFF-PIPE HOUSING FOR HOT-HUMID AND HOT-ARID CLIMATES  

E-Print Network (OSTI)

This paper investigates the feasibility of off-grid, off-pipe housing in hot-humid and hot-arid climates in the U.S. The study aims to eliminate the need for non-renewable sources of energy and municipal water in residences by using off-grid, off-pipe design approach. To accomplish this, a 2001 International Energy Conservation Code compliant house in Houston, TX and Phoenix, AZ was simulated to determine the base-case energy and water use. Based on the availability of on-site renewable energy and water sources (i.e., solar, wind and biomass and rainfall) in these locations, energy and water efficiency measures were selected in order to reduce the energy and water use to a level that could be met solely by on-site renewable resources. Finally, the sizing of the renewable energy and rainwater harvesting systems was performed to provide for daily needs as well as cumulative needs during the critical periods, in order to achieve complete self sufficiency in terms of energy and water use. The analysis was performed by integrating the results of DOE-2.1e, F-Chart and PV F-Chart programs, and cumulative rainwater supply and water demand analysis. The simulation results demonstrate the differences between the priorities for energy efficiency, water-efficiency and renewable energy measures in hot-humid and hot-arid climates.

Experimental results for diffusion and infiltration of moisture in concrete masonry walls exposed to hot and humid climates  

SciTech Connect

This paper presents experimental test results for heat and moisture migration in walls exposed to hot and humid climates. The research was conducted to study the problem of mold and mildew caused by moisture transfer into walls of concrete masonry unit (CMU) type construction by diffusion and convective transport by air infiltration. This type of construction is common in commercial buildings in the southern US. The tests were conducted in two phases. Phase 1 evaluated heat and moisture transfer by diffusion. Phase 2 testing involved air infiltration through the test walls. Data were also collected to determine the rate at which the test walls would dry out without infiltration present. Test results indicate that an exterior vapor retarder will reduce the moisture migration into the wall and thereby lower the moisture accumulation due to infiltration when a vapor retarder (such as vinyl wallpaper) is used for the interior surface treatment. Testing also showed that while the exterior wall treatment does have an effect on reducing the total moisture accumulation in the test walls, the interior wall treatment has a much larger impact when infiltration is present. The data support a proposed criterion for the onset of mold and mildew, which requires a monthly average surface relative humidity of 80% with temperatures between 32 F and 105 F.

Analysis of Innovative HVAC System Technologies and Their Application for Office Buildings in Hot and Humid Climates  

E-Print Network (OSTI)

ABSTRACT Analysis of Innovative HVAC System Technologies and Their Application for Office Buildings in Hot and Humid Climates. (December 2010) Oleksandr Tanskyi, B.S., National Technical University of Ukraine; M.S., National Technical University of Ukraine Co-Chairs of Advisory Committee: Dr. David E. Claridge Dr. Michael B. Pate The commercial buildings sector in the United States used 18% (17.93 Quads) of the U.S. primary energy in 2006. Office buildings are the largest single energy consumption category in the commercial buildings sector of the United States with annual energy consumption around 1.1 Quads. Traditional approaches used in commercial building designs are not adequate to save energy in both depth and scale. One of the most effective ways to reduce energy consumption is to improve energy performance of HVAC systems. High-performance HVAC systems and components, as well as application of renewable energy sources, were surveyed for buildings in hot and humid climates. An analysis of performance and energy saving potential estimation for selected HVAC systems in hot and humid climates was developed based on energy consumption simulation models in DOE-2.1E. A calibrated energy consumption model of an existing office building located in the hot and humid climate conditions of Texas was developed. Based on this model, the energy saving potential of the building was estimated. In addition, energy consumption simulation models were developed for a new office building, including simulation of energy saving measures that could be achieved with further improvements of HVAC system above the energy conservation codes requirements. The theoretical minimum energy consumption level for the same office building was estimated for the purpose of evaluating the whole building energy efficiency level. The theoretical minimum energy consumption model of the office building was designed to provide the same level of comfort and services to the building occupants as provided in the actual building simulation model. Finally, the energy efficiency of the building that satisfies valid energy conservation codes and the building with an improved HVAC system was estimated based on theoretically minimum energy consumption level. The analysis provided herein can be used for new building practitioners and existing building owners to evaluate energy reduction potential and the performance of innovative technologies such as dedicated outdoor air system, displacement ventilation, improved cooling system efficiency, air source heat pumps and natural gas heat pumps.

Residential Dehumidification Systems Research for Hot-Humid Climates: September 1, 2001 -- December 30, 2003  

SciTech Connect

Twenty homes were tested and monitored in the hot-humid climate of Houston, Texas, U.S.A., to evaluate the humidity control performance and operating cost of six different integrated dehumidification and ventilation systems that could be applied by production homebuilders. Temperature and relative humidity were monitored at four living-space locations and in the conditioned attic where the space-conditioning equipment and air-distribution ducts were located. Equipment operational time was monitored for heating, cooling, dehumidification, and ventilation. Results showed that energy efficiency measures, combined with controlled mechanical ventilation, change the sensible and latent cooling load fractions such that dehumidification separate from the cooling system is required to maintain indoor relative humidity below 60% throughout the year. The system providing the best overall value, including humidity control, first cost, and operating cost, involved a standard dehumidifier located in a hall closet with a louvered door and central-fan-integrated supply ventilation with fan cycling.

Relative Humidity Sensing Properties Of Cu{sub 2}O Doped ZnO Nanocomposite  

Science Conference Proceedings (OSTI)

In this paper we report application of Cu{sub 2}O doped ZnO composite prepared by solid state reaction route as humidity sensor. Pellet samples of ZnO-Cu{sub 2}O nanocrystalline powders with 2, 5 and 10 weight% of Cu{sub 2}O in ZnO have been prepared. Pellets have been annealed at temperatures of 200-500 deg. C and exposed to humidity. It is observed that as relative humidity increases, resistance of the pellet decreases for the humidity from 10% to 90%. Sample with 5% of Cu{sub 2}O doped in ZnO and annealed at 500 deg. C shows best results with sensitivity of 1.50 M{omega}/%RH. In this case the hysteresis is low and the reproducibility high, making it the suitable candidate for humidity sensing.

An Analysis of Low Cost, Energy Efficient, Housing for Low-income Residents of How and Humid Climates  

E-Print Network (OSTI)

The purpose of this research is to develop methods that will enable the reduction of owning and operating costs of low-income housing in the hot-humid climates of the U. S. The objectives include investigating various scenarios that will enable the implementation of cost-effective construction of low-income housing using volunteer labor. The research uses a case study approach where a base-line energy use is established using a comparative Princeton Score Keeping Method (PRISM) analysis and measurements from a case study house. A prototype house is then simulated with the DOE-2 building simulation program, and the energy savings calculated by comparing simulated energy and water conservation design measures (E&WCDMs) with the calibrated baseline energy simulation. The cost and maintenance of the house are analyzed with the real cost of construction of a case study house in Bryan/College Station, Texas.

EFFECT OF TEMPERATURE AND HUMIDITY ON FORMALDEHYDE EMISSIONS IN TEMPORARY HOUSING UNITS  

SciTech Connect

The effect of temperature and humidity on formaldehyde emissions from samples collected from temporary housing units (THUs) was studied. The THUs were supplied by the U.S Federal Emergency Management Administration (FEMA) to families that lost their homes in Louisiana and Mississippi during the Hurricane Katrina and Rita disasters. Based on a previous study 1, 2, four of the composite wood surface materials that dominated contributions to indoor formaldehyde were selected to analyze the effects of temperature and humidity on the emission factors. Humidity equilibration experiments were carried out on two of the samples to determine how long the samples take to equilibrate with the surrounding environmental conditions. Small chamber experiments were then conducted to measure emission factors for the four surface materials at various temperature and humidity conditions. The samples were analyzed for formaldehyde via high performance liquid chromatography. The experiments showed that increases in temperature or humidity contributed to an increase in emission factors. A linear regression model was built using natural log of percentage relative humidity (RH) and inverse of temperature (in K) as predictor variables, and natural log of emission factors as the target variable. The coefficients of both inverse temperature and log relative humidity with log emission factor were found to be statistically significant for all the samples at the 95percent confidence level. This study should assist to retrospectively estimate indoor formaldehyde exposures of occupants of temporary housing units (THUs).

The Effect of Humidity on the Reliability of a Surface Micromachined Microengine  

SciTech Connect

Humidity is shown to be a strong factor in the wear of rubbing surfaces in polysilicon micromachines. We demonstrate that very low humidity can lead to very high wear without a significant change in reliability. We show that the volume of wear debris generated is a function of the humidity in an air environment. As the humidity decreases, the wear debris generated increases. For the higher humidity levels, the formation of surface hydroxides may act as a lubricant. The dominant failure mechanism has been identified as wear. The wear debris has been identified as amorphous oxidized silicon. Large slivers (approximately 1 micron in length) of debris observed at the low humidity level were also amorphous oxidized silicon. Using transmission electron microscopy, we observed that the wear debris forms spherical and rod-like shapes. We compared two surface treatment processes: a fluorinated si- lane chain, (FITl) and supercritical C02 dried (SCC02). The microengines using the SCC02 process were found to be less reliable than those released with the FIX process under two humidity levels.

Analysis of improved fenestration for code-compliant residential buildings in hot and humid climates  

E-Print Network (OSTI)

This thesis presents an analysis of energy efficient residential windows in hot and humid climates. To accomplish this analysis, the use of accurate simulation tools such as DOE-2.1e is required, which incorporates the results from the WINDOW-5.2 simulation program to assess accurate fenestration performance. The thesis also investigates the use of optimal glazing types, which, for future applications, could be specified in the code to reduce annual net energy consumption to zero. Results show that combinations of low-E and double pane, clear-glazed windows, which are optimally shaded according to orientation are the best solution for lowering both annual energy consumption and peak electricity loads. The study also concludes that the method used to model fenestration in the simulation program plays an important role in accurately determining the effectiveness of the glazing option used. In this particular study, the use of the WINDOW-5.2 program is highly recommended especially for high performance windows (i.e., low-E glazing). Finally, a discussion on the incorporation of super high performance windows (i.e., super low-E, ultra low-E and dynamic / switchable glazing) into the IECC code concludes that these types of glazing strategies can reduce annual net energy use of the window to zero. Future work identified by this thesis includes a more extensive examination of the passive solar potential of high performance fenestration, and an examination of the appropriate methods for specifying these properties in future versions of the IECC code. This implies that future specifications for fenestration in the IECC code could aim for zero net annual energy consumption levels from residential fenestration.

Evaluation of ANSI N42-17A by investigating the effects of temperature and humidity on the response of radiological instruments  

SciTech Connect

The American National Standards Institute (ANSI) N42.17A-1989 standard`s performance criteria and test methods has been evaluated by investigating the effects of temperature and humidity on the response of 105 portable direct-reading radiological instruments (45 beta-gamma survey meters, 32 neutron rem meters, 1O alpha contamination and 18 tritium-in-air monitors). The US Department of Energy (DOE) mandates the use of ANSI standards for the calibration and performance testing of radiological instruments, and requires that instruments be appropriate for existing environmental conditions. Random tests conducted in an environmental chamber determined the effects of temperatures ranging from {minus}10{degree}C to 50{degree}C and humidity at levels of 40% RH and 95% RH on the response of a cross section of instruments used in routine health physics operations at Los Alamos. The following instruments were tested: Eberline RO-2 and RO-C ionization chambers, Eberline E-530 survey meter with the Model HP-C stainless steel Geiger-Muller (G) wall probe, Eberline PIC-6A and PIC-6B ion chambers, Eberline ESP-1 survey meter with the Model HP-260 pancake G detector, Ludlum 3 survey meter with the Model 44-6 stainless steel G wall probe, Eberline ESP-1, ESP-2 and PAR-4 survey meters with the neutron rem detector, Health Physics Instruments 2080 survey meter with the moderator detector, Ludlum 139 survey meter with the Model 43-32 air-proportional alpha detector, and the Overhoff 394-C, Johnston J-111 and J-110 tritium monitors. Experimental results encompass 1128 temperature tests (1269-hours exposure in the chamber) and 735 humidity tests (1890-hours exposure in the chamber). The study shows the standard`s test requirement for temperature at or near the extreme conditions, and the standard`s test requirement for humidity at 95% RH may be too restrictive for instruments used in the work environment.

Calculation of the performance of activated carbon at high relative humidities  

SciTech Connect

The Dubinin-Radushkevich potential theory was extended to include a term giving the effect of relative humidity on the uptake of adsorbate. This extended equation permit the adsorptive capacity of the activated charcoal in a respirator cartridge to be estimated for any combination of temperature, relative humidity, and concentration of contaminant. Application of this theory to previously published data of Werner showed a good correlation between theory and experiment. This equation is consistent with the experimental observations that 1) below a certain value, the relative humidity has little effect on the uptake of adsorbate, and 2) the effect of relative humidity, if observed, is more severe for lower than for higher concentration of contaminant.

A theoretical model for adsorption capacities of charcoal beds: I, Relative humidity effects  

SciTech Connect

Water vapor is the major interferent in the adsorption of other vapors from air when that air is passed through an activated charcoal bed. A limited amount of data (published and unpublished) is available on the magnitudes of capacity (or service life) reduction as a function of relative humidity (water vapor concentration) and preadsorbed water. A simple equilibrium model has been developed which quantitatively explains observed humidity effects and allows extrapolation of data to untested conditions. 9 refs., 4 figs., 2 tabs.

Uncertainties in climatological tropical humidity profiles: Some implications for estimating the greenhouse effect  

SciTech Connect

The vertical profile of water vapor, the principal infrared-absorbing gas in the atmosphere, is an important factor in determining the energy balance of the climate system. This study examines uncertainties in calculating a climatological humidity profile: specifically one derived from radiosonde data representative of the moist and highly convective region over the western tropical Pacific Ocean. Uncertainties in the humidity data are large in conditions of low temperature or low humidity in the mid- and upper troposphere. Results derived from a single United States station (Koror) and from an average of four United States-operated stations (all near the equator west of the date line) yield nearly identical results. No humidity measurements are reported in fully the upper third of the troposphere. The implications of these uncertainties for determining the climatological humidity profile are quantitatively assessed by bracketing the range of plausible assumptions for unreported humidity to produce extreme estimates of the climatological profile. These profiles, together with the observed climatological temperature profile, are used as input to a radiative transfer model to ascertain the uncertainty in clear-sky outgoing infrared radiance due to water vapor uncertainties. The radiance uncertainty is shown to be comparable in magnitude to the purely radiative response of the tropical atmosphere to doubling carbon dioxide. The uncertainty associated with unmeasured upper-tropospheric humidity is approximately equal to that arising from incompletely measured midtropospheric humidity. Clear-sky radiative uncertainties, however, are modest relative to the uncertainty associated with variations of infrared absorption due to clouds, as demonstrated by introducing citrus ice particles into the radiative transfer calculations.

Impact of the humidity pump on indoor environments. Final report, August 1989-November 1990  

SciTech Connect

The impact of the humidity pump, (a newly developed, gas-fired, liquid desiccant, make-up air conditioning unit) on the indoor air environment of two office buildings was investigated during a two month field program. The study generated a data base and gained insights on indoor air quality (IAQ), comfort, and ventilation parameters of each building operating under routine conditions. The objective of the study was to determine the impact of the humidity pump on (1) indoor pollution concentration levels; (2) comfort parameters as perceived by occupants of and visitors to each building; and (3) building ventilation (energy) parameters. Each objective was attained by testing the null hypothesis (Operation of the humidity pump has no impact.) The null hypothesis was tested on occupant exposure levels. Consequently, it was rejected only if the humidity pump affects potential factors that may alter significantly pollutant concentrations, comfort levels, and ventilation rates. Operation of the humidity pump affects levels of volatile organic compounds and microbiological conditions. The humidity pump did not affect comfort and ventilation parameters.

ZnSe nanorods prepared in hydroxide-melts and their application as a humidity sensor  

Science Conference Proceedings (OSTI)

We have synthesized the crystalline ZnSe nanorods for the first time using the molten hydroxides as reaction solvent in the absence of organic dispersant or capping agents. The products are characterized by X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy. The diameters of ZnSe nanorods are about 200-300 nm, and the lengths are about 1-2 {mu}m. Humidity sensors based on ZnSe nanorods are fabricated and their responsiveness to humidity on static and dynamic testing are investigated. The change of resistance is about three orders of magnitude as the relative humidity increases from 20% to 85%. The response time and recovery time is 50 s and 81 s versus the changes of relative humidity from 20% to 85% and from 85% to 20%, respectively. Our sensor offers higher sensitivity, as well as much better stability and reproducibility than the humidity sensor of ZnSe nanostructure reported before.

Effects of temperature and humidity variations on the stability of coal mine roof rocks. Final report  

SciTech Connect

A high degree of correlation between strain developed in samples of roof rock and humidity changes was obtained in the laboratory. The strain developed across bedding planes was greater than strain developed parallel to bedding. In tests conducted underground, strain values were much lower and the data more scattered for similar humidity variations. Roof rock specimens reacted to a 10 pct change in humidity throughout a 7 to 10 day period before stabilizing, which seems to rule out daily humidity cycles as a factor in roof deterioration and indicates seasonal variations as a major cause. Very low annual temperature variations were recorded in active sections of the mine. At a 6 F annual variation developed strain would be only 10.5 microinches per inch, far below the strain magnitude for humidity variations and probably too low to be a factor in problems of roof deterioration. Laboratory strain tests on drill core samples were shown to be indicators of moisture sensitivity of roof rock, but neither chemical nor physical properties of the samples correlated with the strain data.

Calibrating DOE-2 to Weather and Non-Weather-Dependent Loads for a Commercial Building: Data Processing Routines to Calibrate a DOE-2 Model, Volume II  

E-Print Network (OSTI)

DOE-2 yields hourly data on specific variables provided the user specifies the HOURLY-REPORT instruction. Analyzing the simulation results with hourly data gives a more detailed picture of how well the model is predicting the monitored energy consumption. The difficulties of using hourly data to calibrate a model are the extraction of data from DOE-2's well documented output reports and processing the data into graphs which are meaningful. This chapter demonstrates the data processing routines that extract hourly end-use energy consumption and weather data from DOE-2's hourly output reports and process the data into three-dimensional plots and temperature-specific humidity carpet plots.

Control Humidity With Single-Duct, Single-Zone, Constant Air Volume System  

E-Print Network (OSTI)

The lecture hall of the Richardson Petroleum Building at Texas A&M University is a large lecture hall, with a total floor area of approximately 2500 ft^2. The lecture hall was served by a constant air volume (CAV) air handling unit (AHU) which had no reheat coil. This resulted in high room humidity levels although the room temperature was satisfied for part load conditions, especially when there was very little sensible load from the room. This paper presents Continuous Commissioning efforts (CC), which turned this inefficient, humid lecture hall into a comfortable learning environment. This case study also explores other possibilities to solve the humidity control problem with single-duct, single-zone constant air volume systems.

Optimal Outside Air Control for Air Handling Units with Humidity Control  

E-Print Network (OSTI)

Most air handling units (AHUs) in commercial buildings have the (air) economizer cycle to use outside air for free cooling under certain outside air conditions. Ideally the economizer cycle is enabled if outside air enthalpy is less than return air enthalpy. During the economizer cycle, outside air flow is modulated to seek mixed air temperature at a supply air temperature set point. Since the outside air may be dry during the economizer cycle, humidification is required for AHUs with humidity control. As a result, the economizer cycle saves cooling energy but requires excessive steam for humidification. Therefore the economizer cycle may not be economical. An optimal outside air control method is developed to minimize the total cost of mechanical cooling and steam humidification. The impacts of chilled water price, steam price, and space minimum humidity set point are analyzed. Finally the optimal outside air control zones are presented on a psychrometric chart under differential energy price ratios and minimum indoor humidity set points.

Internal Microclimate Resulting From Ventilated Attics in Hot and Humid Regions  

E-Print Network (OSTI)

Ventilated spaces in the built environment create unique and beneficial microclimates. While the current trends in building physics suggest sealing attics and crawlspaces, comprehensive research still supports the benefits of the ventilated microclimate. Data collected at the University of Florida Energy Park show the attic environment of asphalt shingled roofs to be typically hotter than the outdoor conditions, but when properly ventilated sustains a much lower relative humidity. The hot, humid regions of the United States can utilize this internally convective, exchanging air mass to provide stable moisture levels within attic spaces. Positioning the buildings primary boundary at the ceiling deck allows for utilization of this buffer climate to minimize moisture trapping in insulation and maximize the insulation’s thermal benefits. This investigation concludes the conditions in a ventilated attic are stable through seasonal changes and promotes cost effective, energy efficient climate control of unconditioned spaces in hot, humid regions.

Statistical comparison of the effect of relative and absolute humidity on fixed-bed carbon adsorption capacity. Report for January 1987-July 1988  

SciTech Connect

This paper describes statistical methods used to evaluate data for toluene (at several typical operating temperatures and humidity levels) and to determine which measure of humidity (relative or absolute) is more important in determining carbon adsorption efficiency. The water content of a solvent-laden stream is critical for its control via carbon adsorption, especially at relative humidities about 50-70%. (Relative humidity is the percent of saturation: absolute humidity is the total water content.)

Effects of high humidity on translocation of foliar-applied labeled compounds in plants. II. Translocation from starved leaves  

SciTech Connect

Absorption and translocation of chemicals by cotton leaves are greatly increased under conditions of high humidity. This enhanced movement consists of increased phloem transport and induced uptake into and transport via the xylem. Studies with starved and normal leaves prove that phloem transport is greatly reduced in leaves depleted of carbohydrate reserves; starvation has no effect upon the xylem transport induced by high humidity. The relation of high humidity to herbicide usage is discussed. 15 references, 6 figures.

Moisture performance of sealed attics in the mixed-humid climate  

SciTech Connect

Oak Ridge National Laboratory studied 8 homes in the mixed-humid climate, 4 with vented attics and 4 with sealed attics. ORNL wanted to understand the moisture performance of the sealed attic and how it affected the interior environment. We found that the attic and interior of sealed attic homes were more humid than the attic and interior observed in vented attic homes. This is due to the lack of ventilation in the sealed attic. Historically attics have been vented to dehumidify the attic and interior of the home. A sealed attic design greatly reduces the venting potential and thus this drying pathway and can cause elevated interior moisture over a vented attic home. Despite the elevated attic and interior moisture in the sealed attic homes, so far no mold or material degradation has been found. The roof sheathing moisture content has stayed below 20%, indicating low potential for material degradation. Also the relative humidity at the roof sheathing has stayed within the ASHRAE 160 design criteria except for a short time during the 2011/2012 winter. This was due to a combination of the sealed attic design (minimal venting to the outside) and the duct work not being operated in the attic which usually provides a dehumidification pathway. It was also found that when the humidity was controlled using the HVAC system, it resulted in 7% more cooling energy consumption. In the mixed-humid climate this reduces the cost effectiveness of the sealed attic design as a solution for bringing ducts into a semi-conditioned space. Because of this we are recommending the other alternatives be used to bringing ducts into the conditioned space in both new construction and retrofit work in the mixed-humid climate.

Effect of Humidity on the Composition of Isoprene Photooxidation Secondary Organic Aerosol  

Science Conference Proceedings (OSTI)

The effect of relative humidity (RH) on the composition and concentrations of gas-phase products and secondary organic aerosol (SOA) generated from the photooxidation of isoprene under high-NOx conditions was investigated. The yields of most gas-phase products were the same regardless of initial water vapor concentration with exception of hydroxyacetone and glycolaldehyde, which were considerably affected by RH. A significant change was observed in the SOA composition, with many unique condensed-phase products formed under humid (90% RH) vs. dry (<2% RH) conditions, without any observable effect on the rate and extent of the SOA mass growth.

Comparison of temperature and humidity profiles with elastic-backscatter lidar data  

SciTech Connect

This contribution analyzes elastic-backscatter lidar data and temperature and humidity profiles from radiosondes acquired in Barcelona in July 1992. Elastic-backscatter lidar data reveal the distribution of aerosols within the volume of atmosphere scanned. By comparing this information with temperature and humidity profiles of the atmosphere at a similar time, we are able to asses de relationship among aerosol distribution and atmospheric stability or water content, respectively. Comparisons have shown how lidar`s revealed layers of aerosols correspond to atmospheric layers with different stability condition and water content.

Long-term corrosion/oxidation studies under controlled humidity conditions  

SciTech Connect

Independent of thermal loading scenarios, the waste packages at the potential repository at Yucca Mountain, Nevada will be exposed to environmental conditions where there is the possibility of significant water film formation occurring on the waste packages. Water films can cause aggressive aqueous film electrochemical corrosion on susceptible metals or alloys. Water film formation will be facilitated when relative humidities are high, when hygroscopic salts are present on the surfaces, when corrosion products are hygroscopic, and when particles form crevices with the surfaces (capillary effect). Also certain gaseous contaminants, such as, NO{sub x} and SO{sub 2}, can facilitate water film formation. It should be noted that water film formation can occur at isolated spots (e.g. surface defects and salt particles) and need not cover the entire surface for electrochemical corrosion to occur. This activity will characterize the long term corrosion of metal specimens at two nominal relative humidities (50 and 85%) and at 80 C. Under the low relative humidity (50%) condition, water film formation is expected to be limited and therefore aqueous film electrochemical corrosion is expected also to be limited. Under the high relative humidity (85%) condition, significant water film formation is expected to occur under some test conditions, and subsequently aqueous film electrochemical corrosion will occur on susceptible materials.

Measurements of the effects of humidity on radio-aerosol penetration through ultrafine capillaries  

SciTech Connect

The purpose of this research was to examine the effects of humidity on radio-aerosol penetration through ultrafine capillaries. A number of tests were conducted at relative humidities of 20%, 50%, and 80%, with sampling times of 20, 40, and 60 min. The radio-aerosol consisted of polystyrene particles with a diameter of 0.1 {micro}m. The ultrafine capillaries had a diameter of 250 {micro}m. The data from these tests varied significantly. These results made the identification of radio-aerosol penetration trends inconclusive. The standard deviation for all penetration data ranged from 3% to 30%. The results of this study suggest that a better control of the experimental parameters was needed to obtain more accurate data from experiments associated with radio-aerosol penetration in the presence of moisture. The experimental parameters that may have contributed to the wide variance of data, include aerosol flow, radio-aerosol generation, capillary characteristics, humidity control, and radiation measurements. It was the uncertainty of these parameters that contributed to the poor data which made conclusive deductions about radio-aerosol penetration dependence on humidity difficult. The application of this study is to ultrafine leaks resulting from stress fractures in high-level nuclear waste transportation casks under accident scenarios.

Building Design and Operation for Improving Thermal Comfort in Naturally Ventilated Buildings in a Hot-Humid Climate  

E-Print Network (OSTI)

The goal of this research was to develop new techniques for designing and operating unconditioned buildings in a hot-humid climate that could contribute to an improvement of thermal performance and comfort condition. The recommendations proposed in this research will also be useful for facility managers on how to maintain unconditioned buildings in this climate. This study investigated two unconditioned Thai Buddhist temples located in the urban area of Bangkok, Thailand. One is a 100-year-old, high-mass temple. The other is a 5-year-old, lower-mass temple. The indoor measurements revealed that the thermal condition inside both temples exceed the ASHRAE-recommended comfort zone. Surprisingly, the older temple maintained a more comfortable indoor condition due to its thermal inertia, shading, and earth contacts. A baseline thermal and airflow model of the old temple was established using a calibrated computer simulation method. To accomplish this, HEATX, a 3-D Computational Fluid Dynamics (CFD) code, was coupled with the DOE-2 thermal simulation program. HEATX was used to calculate the airflow rate and the surface convection coefficients for DOE-2, and DOE-2 was used to provide physical input variables to form the boundary conditions for HEATX. In this way calibrated DOE-2/CFD simulation model was accomplished, and the baseline model was obtained. To investigate an improved design, four design options were studied: 1) a reflective or low-solar absorption roof, 2) R-30 ceiling insulation, 3) shading devices, and 4) attic ventilation. Each was operated using three modes of ventilation. The low-absorption roof and the R-30 ceiling insulation options were found to be the most effective options, whereas the shading devices and attic ventilation were less effective options, regardless of which ventilation mode was applied. All design options performed much better when nighttime-only ventilation was used. Based on this analysis, two prototype temples was proposed (i.e., low-mass and high-mass temples). From the simulation results of the two prototypes, design and operation guidelines are proposed, which consist of: 1) increased wall and ceiling insulation, 2) white-colored, low-absorption roof, 3) slab-on-ground floor, 4) shading devices, 5) nighttime-only ventilation, 6) attic ventilation, and 7) wider openings to increase the natural ventilation air flow windows, wing walls, and vertical fins.

Winchester/Camberley Homes New Construction Test House Design, Construction, and Short-Term Testing in a Mixed-Humid Climate  

SciTech Connect

The NAHB Research Center partnered with production builder Winchester/Camberley Homes to build a DOE Building America New Construction Test House (NCTH). This single family, detached house, located in the mixed-humid climate zone of Silver Spring, MD, was completed in June 2011. The primary goal for this house was to improve energy efficiency by 30% over the Building America B10 benchmark by developing and implementing an optimized energy solutions package design that could be cost effectively and reliably constructed on a production basis using quality management practices. The intent of this report is to outline the features of this house, discuss the implementation of the energy efficient design, and report on short-term testing results. During the interactive design process of this project, numerous iterations of the framing, air sealing, insulation, and space conditioning systems were evaluated for energy performance, cost, and practical implementation. The final design featured numerous advanced framing techniques, high levels of insulation, and the HVAC system entirely within conditioned space. Short-term testing confirmed a very tight thermal envelope and efficient and effective heating and cooling. In addition, relevant heating, cooling, humidity, energy, and wall cavity moisture data will be collected and presented in a future long-term report.

Critical Plane Analysis of Wall Assembly in a Hot, Humid Climate  

E-Print Network (OSTI)

Condensation plane analysis for determining critical planes at which condensation may occur can be performed for building assemblies in any climate. Procedures for doing so in heating climates where buildings dry to the outside of envelope assemblies are given in 1997 ASHRAE Fundamentals Handbook, Chapter 22 "Thermal and Moisture Control in Insulated Assemblies - Fundamentals." Little original work is available elsewhere in the literature to guide analysis for buildings in hot and humid climates. Example 1 in Chapter 22 of the Fundamentals Handbook gives step-by-step calculations, for a heating climate. To analyze envelope assemblies in hot and humid climates where drying predominately occurs to the indoors, no direct discussion or examples are available. This paper presents this detail for a typical light commercial wall assembly, and provides the basis for analysis of any envelope assembly in hot and humid climates. Analysis of an envelope assembly in hot and humid climates seeks to determine if there is a critical plane in the wall towards which water vapor flows more rapidly from the outdoors than it flows to the indoors. (In heating climates, the analysis is reversed). In order to do this, weather data must be examined to yield outdoor conditions, and indoor conditions must be identified. Water vapor and thermal resistance of the materials in the wall assembly must also be established. These data are then used to perform calculations using the basic diffusion equation and methods described in the Fundamentals Handbook.' Each potentially critical plane is analyzed to determine if water vapor can accumulate more rapidly than it dissipates. This potential accumulation would signify a heightened risk of equilibrium relative humidity sufficient to amplify microbial growth, or to promote the deterioration of building materials.

Effects of humidity and temperature on the conversion of SO/sub 2/ to particulate sulfate and sulfite. Final report  

SciTech Connect

Effects of humidity and temperature on SO/sub 2/ conversion to particulate sulfate and sulfite in relation to heterogeneous conversion in droplets and on particle surfaces; homogeneous conversion in the gas phase; and gas-to-particle conversion are discussed. Theoretical quantitative expressions for some effects are derived and order-of-magnitude calculations are given. Detailed conclusions and comparisons regarding the effects of temperature and humidity on specific oxidation paths. Major conclusions documented are: rates of SO/sub 2/ to SO/sub 4//sup =/ converison in aqueous droplets are generally negatively correlated with temperature and positively correlated with relative humidity (particularly at high relative humidity); the rates of SO/sub 2/ to SO/sub 4//sup =/ conversion on reactive surfaces can be either positively correlated with relative humidity or unaffected by relative humidity, and can have a negative, a positive, or a zero correlation with temperture; the homogeneous photooxidation is considerably less sensitive to temperature than is the heterogeneous conversion. (The photooxidation of SO/sub 2/ is expected to be positively correlated with temperature, but the correlation will be weaker in clean air than in polluted air, the positive dependence of SO/sub 2/ photooxidation on humidity will be weaker in polluted air containing NMHC than in clean air); the specific conversion paths have rates with highly different sensitivities to relative humidity and temperature. Thus, a given conversion path can become more or less significant relative to other paths as relative humidity and temperature vary. This suggests that temperature and relative humidity variations can be major causes of the temporal and spatial variations in the rate and yield of conversion and in the type of sulfate produced, which in turn determine the extent of adverse environmental effects. 228 references, 1 figure, 28 tables.

Effects of Temperature and Humidity on the Characterization of C-4 Explosive Threats  

Science Conference Proceedings (OSTI)

The amount of time that an explosive is present on the surface of a material is dependent upon the original amount of explosive on the surface, adhesive forces, temperature and humidity, as well as other environmental factors. This laboratory study focused on evaluating RDX crystal morphology changes resulting from variations in temperature and humidity conditions of the sample. The temperature and humidity conditions were controlled using a Tenney THRJ environmental chamber and a Tenney T11RC-1.5 environmental chamber. These chambers allow the temperature and humidity to be held within ±3°C and ±5% RH. The temperature and humidity conditions used for this test series were: 40°F/40%RH, ~70°F/20%RH (samples left on benchtop), 70°F/70%RH, 70°F/95%RH, 95°F/40%RH, 95°F/70%RH, and 95°F/95%RH. These temperature and humidity set points were chosen to represent a wide range of conditions that may be found in real world scenarios. C-4 (RDX crystals and binder material) was deposited on the surface of one of six substrates by placing a fingerprint from the explosive block onto the matrix surface. The substrates were chosen to provide a range of items that are commonly used. Six substrate types were used during these tests: 50% cotton/50% polyester as found in T-shirts, 100% cotton with a smooth surface such as that found in a cotton dress shirt, 100% cotton on a rough surface such as that found on canvas or denim, suede leather such as might be found on jackets, purses, or shoes, painted metal obtained from a junked car hood, and a computer diskette. The samples were not pre-cleaned prior to testing and contained sizing agents, and in the case of the metal: oil, dirt, scratches, and rust spots. The substrates were photographed at various stages of testing, using a Zeiss Discover V12 stereoscope with Axiocam ICc1 3 megapixel digital camera, to determine any changes in the crystalline morphology. Some of the samples were examined using scanning electron microscopy (SEM) and atomic force microscopy (AFM) in an attempt to determine how the explosive was bound to the substrate.

Building a 40% Energy Saving House in the Mixed-Humid Climate  

DOE Green Energy (OSTI)

This report describes a home that uses 40% less energy than the energy-efficient Building America standard - a giant step in the pursuit of affordable near-zero-energy housing through the evolution of five near-zero-energy research houses. This four-bedroom, two-bath, 1232-ft2 house has a Home Energy Rating System (HERS) index of 35 (a HERS rating of 0 is a zero-energy house, a conventional new house would have a HERS rating of 100), which qualifies it for federal energy efficiency and solar incentives. The house is leading to the planned construction of a similar home in Greensburg, Kansas, and 21 staff houses in the Walden Reserve, a 7000-unit "deep green" community in Cookville, Tennessee. Discussions are underway for construction of similar houses in Charleston, South Carolina, Seattle, Washington, Knoxville and Oak Ridge, Tennessee, and upstate New York. This house should lead to a 40% and 50% Gate-3, Mixed-Humid-Climate Joule for the DOE Building America Program. The house is constructed with structurally-insulated-panel walls and roof, raised metal-seam roof with infrared reflective coating, airtight envelope (1.65 air changes per hour at 50 Pascal), supply mechanical ventilation, ducts inside the conditioned space, extensive moisture control package, foundation geothermal space heating and cooling system, ZEHcor wall, solar water heater, and a 2.2 kWp grid-connected photovoltaic (PV) system. The detailed specifications for the envelope and the equipment used in ZEH5 compared to all the houses in this series are shown in Tables 1 and 2. Based on a validated computer simulation of ZEH5 with typical occupancy patterns and energy services for four occupants, energy for this all-electric house is predicted to cost only $0.66/day ($0.86/day counting the hookup charges). By contrast, the benchmark house would require $3.56/day, including hookup charges (these costs are based on a 2006 residential rates of $0.07/kWh and solar buyback at $0.15/kWh). The solar fraction for this home located in Lenoir City, Tennessee, is predicted to be as high as 41%(accounting for both solar PV and the solar water heater). This all-electric home is predicted to use 25 kWh/day based on the one year of measured data used to calibrate a whole-building simulation model. Based on two years of measured data, the roof-mounted 2.2 kWp PV system is predicted to generate 7.5 kWh/day. The 2005 cost to commercially construct ZEH5, including builder profit and overhead, is estimated at about $150,000. This cost - for ZEH5's panelized construction, premanufactured utility wall (ZEHcor), foundation geothermal system, and the addition of the walkout lower level, and considering the falling cost for PV - suggests that the construction cost per ft2 for a ZEH5 two-story will be even more cost-competitive. The 2005 construction cost estimate for a finished-out ZEH5 with 2632 ft2 is $222,000 or $85/ft2. The intention of this report is to help builders and homeowners make the decision to build zero-energy-ready homes. Detailed drawings, specifications, and lessons learned in the construction and analysis of data from about 100 sensors monitoring thermal performance for a one-year period are presented. This information should be specifically useful to those considering structural insulated panel walls and roof, foundation geothermal space heating and cooling, solar water heater and roof-mounted, photovoltaic, grid-tied systems.

Energy Conservation Experiences with HVAC Systems in the High Humidity Climate, A Case History  

E-Print Network (OSTI)

The purpose of this paper is to discuss several commonly encountered problems associated with attempts to air condition buildings in the humid environment. It, first, reports observations made in the course of studying the air conditioning systems in approximately one hundred buildings at USMC Camp Smedley D. Butler in Okinawa, Japan. Three common problems are then discussed in some detail. It was found that in many cases humidity considerations lead to situations which were energy wasteful. In many instances this could be attributed to either design or operational errors. The most common error found was the selection of an improper method of capacity control. Methods of improved capacity control are suggested and the need for additional work is pointed out.

Effect of Return Air Leakage on Air Conditioner Performance in Hot/Humid Climates  

E-Print Network (OSTI)

An experimental study was conducted to quantify the effect of return air leakage from hot/humid attic spaces on the performance of a residential air conditioner. Tests were conducted in psychrometric facilities where temperatures and humidities could be controlled closely. Return air leakage from hot attic spaces was simulated by assuming adiabatic mixing of the indoor air at normal conditions with the attic air at high temperatures. Effective capacity and Energy Efficiency Ratio both decreased with increased return air leakage. However, power consumption was relatively constant for all variables except outdoor temperature, which meant that for the same power consumption, the unit delivered much lower performance when there was return air leakage. The increase in sensible heat ratio (SHR) with increasing leakage showed one of the most detrimental effects of return air leakage on performance.

Start-Up of Air Conditioning Systems After Periods of Shutdown (Humidity Considerations)  

E-Print Network (OSTI)

In many cases the single most important energy conservation measure that can be taken is to turn equipment off when it is not needed. In the case of air conditioning, this generally means turning it off when occupants leave and turning it back on in time to have the space comfortable when they return. In humid climates special problems are often encountered when a system is restarted after a period of shutdown. The temperature and humidity in the space rises during the period of shutdown. Unfortunately the latent load required to bring the space back to comfort conditions is usually much higher than the sensible load. Most methods of control are ill suited for this duty. This paper examines the response of various types of air conditioning systems during this recovery period and makes recommendations for system designers.

Technical and Economic Analysis of Solar Cooling Systems in a Hot and Humid Climate  

E-Print Network (OSTI)

The aim of this paper is to promote efficient and cost effective implementation of advanced solar cooling systems and techniques for the hot and humid climates cities in the United States. After an introduction of basic principles, the development history and recent progress in solar cooling technologies are reported. Nevertheless, the economics of solar energy systems are particularly complex with much inevitable uncertainty due to several factors. In this paper, a simplified comprehensive economic optimization model is developed to determine whether a particular solar system is economically advantageous for a particular project. This model explains and illustrates with simple, but realistic examples the use of life-cycle cost analysis and benefit-cost analysis to evaluate and compare the economic efficiency of the solar cooling system. Consequently, under appropriate conditions, solar or solar-assisted air conditioning systems may be reasonable alternatives to conventional air-conditioning systems in a hot and humid climate.

Better Unitary Equipment Air-Handlers for Efficiency and Humidity Control  

E-Print Network (OSTI)

Regulatory requirements drive unitary equipment design. For residential equipment, SEER reflects performance at moderate temperatures, and is largely independent of high temperature efficiency and high latent heat removal capability. The test procedure gives too little credit for advanced air handlers that reduce air conditioning load and facilitate adaptive humidity control through automatic fan speed adjustment. DC permanent magnet variable speed motors have much lower market share than less efficient permanent split capacitor designs: changing saves 15% - 25% at high fan speed, and at least 50% at lower speeds (high latent cooling). Humidistats allow dynamic humidity control by reducing air flow, cooling the evaporator. Following market transformation to increase market share, federal equipment stanards should be augmented to include specific air handler air flow efficiency levels, such as 0.2 watts/cfm at size-dependent static pressures. We estimate that customer payback will be less than three years in a mature market.

Impacts of humidity and temperature on the performance of transparent conducting zinc oxide.  

Science Conference Proceedings (OSTI)

The impact of humidity and temperature on a zinc oxide based transparent conducting oxide (TCO) was assessed under accelerated aging conditions. An in situ electroanalytical method was used to monitor the electrical properties for a conducting zinc oxide under controlled atmospheric (humidity, temperature and irradiation) conditions. A review of thin film photovoltaic (PV) literature has shown one major failure mode of cells/modules is associated with the ingress of water into modules in the field. Water contamination has been shown to degrade the performance of the TCO in addition to corroding interconnects and other conductive metals/materials associated with the module. Water ingress is particularly problematic in flexible thin film PV modules since traditional encapsulates such as poly(ethyl vinyl acetate) (EVA) have high water vapor transmission rates. The accelerated aging studies of the zinc oxide based TCOs will allow acceleration factors and kinetic parameters to be determined for reliability purposes.

Abnormal humidity-dependent electrical properties of amorphous carbon/silicon heterojunctions  

Science Conference Proceedings (OSTI)

Amorphous carbon (a-C) film/n-Si heterojunctions have been fabricated by pulse laser deposition, and their current-voltage characteristics have been investigated. The results show that the atmosphere relative humidity (RH) has a significant effect on the reverse bias I-V characteristics of the heterojunctions. For the low bias voltages, the resistance of the a-C/Si heterojunction decreases with the increase of the RH. However, when the applied voltage is greater than a threshold, the resistance of the a-C/Si heterojunctions increases with the increase of the RH. This humidity-dependent phenomenon is attributed to the charge transfer from the absorbed H{sub 2}O molecular to a-C film.

Using Absolute Humidity and Radiochemical Analyses of Water Vapor Samples to Correct Underestimated Atmospheric Tritium Concentrations  

SciTech Connect

Los Alamos National Laboratory (LANL) emits a wide variety of radioactive air contaminants. An extensive ambient air monitoring network, known as AIRNET, is operated on-site and in surrounding communities to estimate radioactive doses to the public. As part of this monitoring network, water vapor is sampled continuously at more than 50 sites. These water vapor samples are collected every two weeks by absorbing the water vapor in the sampled air with silica gel and then radiochemically analyzing the water for tritium. The data have consistently indicated that LANL emissions cause a small, but measurable impact on local concentrations of tritium. In early 1998, while trying to independently verify the presumed 100% water vapor collection efficiency, the author found that this efficiency was normally lower and reached a minimum of 10 to 20% in the middle of summer. This inefficient collection was discovered by comparing absolute humidity (g/m{sup 3}) calculated from relative humidity and temperature to the amount of water vapor collected by the silica gel per cubic meter of air sampled. Subsequent experiments confirmed that the elevated temperature inside the louvered housing was high enough to reduce the capacity of the silica gel by more than half. In addition, their experiments also demonstrated that, even under optimal conditions, there is not enough silica gel present in the sampling canister to absorb all of the moisture during the higher humidity periods. However, there is a solution to this problem. Ambient tritium concentrations have been recalculated by using the absolute humidity values and the tritium analyses. These recalculated tritium concentrations were two to three times higher than previously reported. Future tritium concentrations will also be determined in the same manner. Finally, the water vapor collection process will be changed by relocating the sampling canister outside the housing to increase collection efficiency and, therefore, comparability to the true ambient concentrations of tritium.

Indoor Humidity Analysis of an Integrated Radiant Cooling and Desiccant Ventilation System  

E-Print Network (OSTI)

Radiant cooling is credited with improving energy efficiency and enhancing the comfort level as an alternative method of space cooling in mild and dry climates, according to recent research. Since radiant cooling panels lack the capability to remove latent heat, they normally are used in conjunction with an independent ventilation system, which is capable of decoupling the space sensible and latent loads. Condensation concerns limit the application of radiant cooling. This paper studies the dehumidification processes of solid desiccant systems and investigates the factors that affect the humidity levels of a radiantly cooled space. Hourly indoor humidity is simulated at eight different operating conditions in a radiantly cooled test-bed office. The simulation results show that infiltration and ventilation flow rates are the main factors affecting indoor humidity level and energy consumption in a radiantly cooled space with relatively constant occupancy. It is found that condensation is hard to control in a leaky office operated with the required ventilation rate. Slightly pressurizing the space is recommended for radiant cooling. The energy consumption simulation shows that a passive desiccant wheel can recover about 50% of the ventilation load.

El Roque de Los Muchachos Site Characteristics. II. Analysis of Wind, Relative Humidity and Air Pressure  

E-Print Network (OSTI)

In this paper we present an analysis of wind speed, wind direction, relative humidity and air pressure taken at TNG, CAMC and NOT at Observatorio del Roque de Los Muchachos, in the Canary Islands. Data are compared in order to check local variations and both long term and short term trends of the microclimate. Furthermore, influence of wind speed on the astronomical seeing is estimated to the aim to better understand the influence of wide scale parameters on local meteorological data. The three telescopes show different prevailing wind direction, wind speed, relative humidity and air pressure confirming differences in local microclimate. We found that seeing deteriorates when wind speed is lower than 3.3 m/s. Comparison in terms of wind speed and high relative humidity (> 90%) shows that TNG seems to have optimal observational conditions with respect to CAMC and NOT. Air pressure analysis shows that ORM is dominated by high pressure. Short time variations of pressure anticipate temperature variations tipically by 2-3 hours, this property vanishes in time scales higher than some hours and disappear in longer time scales.

Humidity Control Systems for Civil Buildings in Hot Summer and Cold Winter Zone in China  

E-Print Network (OSTI)

In the hot summer and cold winter zone, moisture-laden outside air poses real problems for proper ventilation, air-conditioner sizing, and strategies to overcome the reduced dehumidification capacity of more energy-efficient air-conditioning (AC) systems. Based on our research, this paper further provides the rate and characteristics of moisture resources in civil buildings. Although the ventilation rate is limited with the minimum ventilation rate in the sanitation ventilation mode of the air conditioning period, dehumidifying period and heating period, the ventilation rate is unrestricted in thermal comfort ventilation mode. It is suggested that the operating conditions of the forced ventilation system should be determined on both outdoor air temperature and outdoor air relative humidity (RH). Therefore, the ventilation system should satisfy these requirements during prolonged periods of high ambient humidity. After a detailed presentation of the technical issues, this paper gives specific recommendations for providing adequate ventilation, moisture control and dehumidifying for buildings in hot-humid climates, and takes both the indoor environmental quality (IEQ) and the building energy efficiency into account. Supplying conditioned ventilation air to the buildings appears to be a promising approach to solve the heath problems associated with excessive indoor RH by installation of a separately controlled unit to dry and cool outdoor air.

The influence of temperature and humidity on the wettability of immersion tin coated printed wiring boards  

SciTech Connect

This paper investigates the merits and drawbacks of immersion tin coatings as potential printed wiring board (PWB) surface finishes. Immersion tin films applied in various thicknesses (0.2 to 2 {mu}m) to different copper substrates were characterized relative to thermal stability and shelflife. Thermal excursions included those typical in mixed technology assembly processes. Exposure to temperature/humidity was varied from near ambient (35{degree}C/85%RH) to harsh (steam aging). A minimum thickness of {approximately}60{mu}in (1.5{mu}m) was determined to be critical for assembly operations involving multiple thermal excursions. Even though formation of Cu-Sn intermetallic compounds (IMC) is facile, at the copper-tin interface, these compounds do not adversely affect the soldering performance, as long as the IMC phase is protected by a tin surface layer. Immersion tin finishes are relatively stable to thermal exposure, but are readily oxidized in the presence of humidity. This oxide growth is directly responsible for solderability degradation. The underlying copper substrate was also found to have a significant impact on the thermal stability of tin films. An electroless copper substrate caused significantly more intermetallic formation, that resulted in poor solderability even under moderate temperature, humidity conditions.

Binary homogeneous nucleation: Temperature and relative humidity fluctuations and non-linearity  

SciTech Connect

This report discusses binary homogeneous nucleation involving H[sub 2]SO[sub 4] and water vapor is thought to be the primary mechanism for new particle formation in the marine boundary layer. Temperature, relative humidity, and partial pressure of H[sub 2]SO[sub 4] vapor are the most important parameters in fixing the binary homogeneous nucleation rate in the H[sub 2]SO[sub 4]/H[sub 2]O system. The combination of thermodynamic calculations and laboratory experiments indicates that this rate varies roughly as the tenth power of the saturation ratio of H[sub 2]SO[sub 4] vapor. Furthermore, the vapor pressure of H[sub 2]SO[sub 4] is a function of temperature, and similar dependencies of the binary homogeneous nucleation rate on relative humidity can be noted as well. These factors thus introduce strong non-linearities into the system, and fluctuations of temperature, relative humidity, and H[sub 2]SO[sub 4] vapor concentrations about mean values may strongly influence the nucleation rate measured in the atmosphere.

Binary homogeneous nucleation: Temperature and relative humidity fluctuations and non-linearity  

SciTech Connect

This report discusses binary homogeneous nucleation involving H{sub 2}SO{sub 4} and water vapor is thought to be the primary mechanism for new particle formation in the marine boundary layer. Temperature, relative humidity, and partial pressure of H{sub 2}SO{sub 4} vapor are the most important parameters in fixing the binary homogeneous nucleation rate in the H{sub 2}SO{sub 4}/H{sub 2}O system. The combination of thermodynamic calculations and laboratory experiments indicates that this rate varies roughly as the tenth power of the saturation ratio of H{sub 2}SO{sub 4} vapor. Furthermore, the vapor pressure of H{sub 2}SO{sub 4} is a function of temperature, and similar dependencies of the binary homogeneous nucleation rate on relative humidity can be noted as well. These factors thus introduce strong non-linearities into the system, and fluctuations of temperature, relative humidity, and H{sub 2}SO{sub 4} vapor concentrations about mean values may strongly influence the nucleation rate measured in the atmosphere.

Flow-temperature-humidity control system operating manual. [Controlled atmospheres for industrial hygiene and air pollution studies  

SciTech Connect

A manual containing operating, maintenance, and troubleshooting procedures for the flow-temperature-humidity control system used at the Lawrence Livermore Laboratory to prepare test atmospheres for industrial hygiene and air pollution studies is presented. The system consists of two basic components: a commercially available temperature/humidity indicator unit and a specially built flow-temperature-humidity control module. Procedures are given for using the control system with a vapor generation system or with a trace-gas flowmeter to add vapor or a trace gas to the airstream after it leaves the control module.

Building America Best Practices Series Volume 16: 40% Whole-House Energy Savings in the Mixed-Humid Climate  

SciTech Connect

This best practices guide is the 16th in a series of guides for builders produced by PNNL for the U.S. Department of Energy’s Building America program. This guide book is a resource to help builders design and construct homes that are among the most energy-efficient available, while addressing issues such as building durability, indoor air quality, and occupant health, safety, and comfort. With the measures described in this guide, builders in the mixed-humid climate can build homes that have whole-house energy savings of 40% over the Building America benchmark with no added overall costs for consumers. The best practices described in this document are based on the results of research and demonstration projects conducted by Building America’s research teams. Building America brings together the nation’s leading building scientists with over 300 production builders to develop, test, and apply innovative, energy-efficient construction practices. Building America builders have found they can build homes that meet these aggressive energy-efficiency goals at no net increased costs to the homeowners. Currently, Building America homes achieve energy savings of 40% greater than the Building America benchmark home (a home built to mid-1990s building practices roughly equivalent to the 1993 Model Energy Code). The recommendations in this document meet or exceed the requirements of the 2009 IECC and 2009 IRC and those requirements are highlighted in the text. Requirements of the 2012 IECC and 2012 IRC are also noted in text and tables throughout the guide. This document will be distributed via the DOE Building America website: www.buildingamerica.gov.

DOE standard: Radiological control  

Science Conference Proceedings (OSTI)

The Department of Energy (DOE) has developed this Standard to assist line managers in meeting their responsibilities for implementing occupational radiological control programs. DOE has established regulatory requirements for occupational radiation protection in Title 10 of the Code of Federal Regulations, Part 835 (10 CFR 835), ``Occupational Radiation Protection``. Failure to comply with these requirements may lead to appropriate enforcement actions as authorized under the Price Anderson Act Amendments (PAAA). While this Standard does not establish requirements, it does restate, paraphrase, or cite many (but not all) of the requirements of 10 CFR 835 and related documents (e.g., occupational safety and health, hazardous materials transportation, and environmental protection standards). Because of the wide range of activities undertaken by DOE and the varying requirements affecting these activities, DOE does not believe that it would be practical or useful to identify and reproduce the entire range of health and safety requirements in this Standard and therefore has not done so. In all cases, DOE cautions the user to review any underlying regulatory and contractual requirements and the primary guidance documents in their original context to ensure that the site program is adequate to ensure continuing compliance with the applicable requirements. To assist its operating entities in achieving and maintaining compliance with the requirements of 10 CFR 835, DOE has established its primary regulatory guidance in the DOE G 441.1 series of Guides. This Standard supplements the DOE G 441.1 series of Guides and serves as a secondary source of guidance for achieving compliance with 10 CFR 835.

The judgment and experience of the architect/engineer still remain the most important elements of building design.

Methodology to Develop and Test an Easy-to-use Procedure for the Preliminary Selection of High-performance Systems for Office Buildings in Hot and Humid Climates  

E-Print Network (OSTI)

A procedure has been developed for the preliminary selection of high-performance systems for office buildings in hot and humid climates. High-performance building systems and components were surveyed for buildings in the U.S., which were applicable for office buildings in hot and humid climates. This research developed a calibrated DOE-2.1e simulation model of a prototypical large office building. In addition, a Simplified Geometry DOE-2.1e (SGDOE-2.1e) model, was also developed, which used a simplified geometry to demonstrate the use of a proposed easy-to-use tool. The calibrated DOE-2.1e simulation model and the SGDOE-2.1e were compared and showed a good match with each. The SGDOE-2.1e model was then further modified based on the ASHRAE Standard 90.1-1999 commercial building energy code. A code-compliant (ASHRAE Standard 90.1-1999) SGDOE-2.1e simulation model was then used as a baseline for the evaluation of the high-performance measures. A total of 14 high-performance measures were implemented including the energy savings, while the comfort level was maintained based on the ASHRAE comfort zone. In addition to the 14 high-performance measures, solar thermal and solar PV system analysis were integrated with the SGDOE-2.1e simulation model to further reduce the annual energy use. Finally, specifications of the proposed easy-to-use simulation tool were developed. This tool includes options to choose systems from the 14 high-performance measures and solar systems. The proposed easy-to-use systems selection tool can be used for new building practitioners and existing building owners as well to evaluate the performance of their new buildings compared to the ASHRAE Standard 90.1-1999 code-compliant building, and to assess the feasibility of implementing high-performance measures to their existing buildings in terms of energy and cost savings.

DOE`s Advanced Turbine Systems Program  

Science Conference Proceedings (OSTI)

This paper discusses the Advanced Turbine Systems (ATS) Program, which is necessary to achieve METC`s vision for future IGCC systems. This major new program is a cooperative effort in which DOE`s Office of Fossil Energy (FE) and Office of Conservation and Renewable Energy (CE) are joining forces with the private sector to develop ultra-high efficiency gas turbine systems. A goal of this Program is to have a utility-size gas turbine with a 60 percent efficiency (lower heating value basis (LHV)) ready for commercialization by the year 2002. (While this paper focuses on utility-size turbines which are the primary interest of this audience, an ultra-high efficiency, industrial-size gas turbine will also be developed in the ATS Program with a comparable improvement in efficiency.) Natural gas is the target fuel of the Program, a recognition by DOE that natural gas will play a significant role in supplying future power generation needs in the US. However, to insure that the US has fuel supply options, ATS designs will be adaptable to coal and biomass fuels. Therefore, the ATS Program will directly benefit IGCC and other advanced coal based power generation systems. Cost and efficiency improvements in the turbine system as well as in the gasification and gas stream cleanup plant sections will enable IGCC to reach a cost target of $1,000--$1,280/kW and an efficiency goal of 52 percent (higher heating value basis (HHV)) in the post-2000 market.

VALIDATION OF THE eCALC COMMERCIAL CODE-COMPLIANT SIMULATION VERSUS MEASURED DATA FROM AN OFFICE BUILDING IN A HOT AND HUMID CLIMATE  

E-Print Network (OSTI)

This paper compares the results of a calibrated simulation of a case-study building versus simulation using the web-based eCALC code-compliant commercial simulation program (Haberl et al., 2004). Previously, as-built calibrated simulation results for the case-study building were performed and reported in Cho and Haberl (2008). In this paper an extension of the previous work is presented using the eCALC commercial simulation model, which uses simplified geometry and ASHRAE Standard 90.1-compliant equipment selection and sizing values for energy calculation. This paper compares the results between the as-built geometry simulation and simplified geometry simulation with similar equipment configuration. The simplified geometry simulation model is a modified-eCALC DOE-2 model that includes simplifications of the case-study building’s characteristics. The modified-eCALC DOE-2 model was intended to be used for the development of an easy-to-use tool for the selection of high-performance systems for office buildings in hot and humid climates, which will be presented in another publication.

To be categorized as conditionally safe, ferrocyanide tanks containing {ge} 8 wt% Na{sub 2}NiFe(CN){sub 6} on an energy equivalent basis (i.e., {ge} 115 cal/g) are required to contain some amount of water. These tests were conducted to determine the equilibrium moisture content of waste simulant at the conditions of 30% relative humidity and 25{degrees}C. This test report was prepared to disseminate data collected from these tests. These data are used to model the waste tank moisture contents and transport. These models can determine if the moisture in these tanks will drop below the defined safety limits.

Daylight Analysis with Microcomputers for School Buildings in a Hot, Humid Climate  

E-Print Network (OSTI)

Daylighting and other passive energy technologies are critical issues that should be considered in the early stages of building planning and architectural design. Both new design and retrofit of existing buildings benefit greatly by use of microcomputer-generated models, especially as they relate to building studies in zones of extreme climate. The hot, humid environment of Louisiana poses unique problems and calls for creative solutions. The use of microcomputers as analytical tools to develop suggestions for optimizing the amount of energy consumed for lighting and climatic comfort is illustrated. The effective use of daylighting can, as might be expected, produce net energy savings in most school buildings.

SRNL PHASE II SHELF LIFE STUDIES - SERIES 1 ROOM TEMPERATURE AND HIGH RELATIVE HUMIDITY  

SciTech Connect

The Savannah River National Laboratory (SRNL) Phase II, Series 1 shelf-life corrosion testing for the Department of Energy Standard 3013 container is presented and discussed in terms of the localized corrosion behavior of Type 304 stainless steel in contact with moist plutonium oxide and chloride salt mixtures and the potential impact to the 3013 inner container. This testing was designed to address the influence of temperature, salt composition, initial salt moisture, residual stress and type of oxide/salt contact on the relative humidity inside a 3013 container and the initiation and propagation of localized corrosion, especially stress corrosion cracking. The integrated plan is being conducted by Los Alamos National Laboratory and SRNL. SRNL is responsible for conducting a corrosion study in small scale vessels containing plutonium oxide and chloride salts under conditions of humidity, temperature and oxide/salt compositions both within the limits of 3013 storage conditions as well as beyond the 3013 storage requirements to identify margins for minimizing the initiation of stress corrosion cracking. These worst case conditions provide data that bound the material packaged in 3013 containers. Phase I of this testing was completed in 2010. The Phase II, Series 1 testing was performed to verify previous results from Phase I testing and extend our understanding about the initiation of stress corrosion cracking and pitting that occur in 304L under conditions of room temperature, high humidity, and a specific plutonium oxide/salt chemistry. These results will aid in bounding the safe storage conditions of plutonium oxides in 3013 containers. A substantial change in the testing was the addition of the capability to monitor relative humidity during test exposure. The results show that under conditions of high initial moisture ({approx}0.5 wt%) and room temperature stress corrosion cracking occurred in 304L teardrop coupons in contact with the oxide/salt mixture at times as short as 85 days. In all cases, the cracking appeared to be associated with pitting or localized general corrosion. Crack initiation at other sites, such as surface imperfections or inclusions, cannot be excluded. Cracks appear in most cases to initiate through an intergranular mode and transition to a transgranular mode.

Enclosed Chambers for Humidity Control And Sample Containment in Fiber Diffraction  

Science Conference Proceedings (OSTI)

A chamber and stretch frame for making fibers for diffraction is described. The chamber is made from a simple plastic cuvette with silicon nitride windows. It is suitable for maintaining constant humidity during fiber drying and data collection, and allows stretching of the fiber and exposure to magnetic fields during sample preparation. If necessary, it provides primary containment for toxic and infectious biological materials. The chamber has been used in fiber diffraction experiments with filamentous plant viruses and a yeast prion protein, and is shown to produce excellent orientation and to maintain hydration and order at the molecular level.

E-Print Network (OSTI)

Transparency in architecture is desirable for many reasons. In order to build transparent buildings with high levels of occupant comfort without compromising energy performance, facade technology and integration of facade and environmental systems become still more advanced. The present paper deals with the development and construction of mechanically ventilated double skin facade with HVAC integration for hot and humid climate like UAE. A case study is presented, illustrating potential benefits of careful application of the available technologies adopting an integrated approach from the early design phases. Moreover, the paper gives an introduction to test and demonstrate the performance of the facade and HVAC integration.

Relative Humidity in Limited Streamer Tubes for Stanford Linear Accelerator Center's BaBar Detector  

SciTech Connect

The BABAR Detector at the Stanford Linear Accelerator Center studies the decay of B mesons created in e{sup +}e{sup -} collisions. The outermost layer of the detector, used to detect muons and neutral hadrons created during this process, is being upgraded from Resistive Plate Chambers (RPCs) to Limited Streamer Tubes (LSTs). The standard-size LST tube consists of eight cells, where a silver-plated wire runs down the center of each. A large potential difference is placed between the wires and ground. Gas flows through a series of modules connected with tubing, typically four. LSTs must be carefully tested before installation, as it will be extremely difficult to repair any damage once installed in the detector. In the testing process, the count rate in most modules showed was stable and consistent with cosmic ray rate over an approximately 500 V operating range between 5400 to 5900 V. The count in some modules, however, was shown to unexpectedly spike near the operation point. In general, the modules through which the gas first flows did not show this problem, but those further along the gas chain were much more likely to do so. The suggestion was that this spike was due to higher humidity in the modules furthest from the fresh, dry inflowing gas, and that the water molecules in more humid modules were adversely affecting the modules' performance. This project studied the effect of humidity in the modules, using a small capacitive humidity sensor (Honeywell). The sensor provided a humidity-dependent output voltage, as well as a temperature measurement from a thermistor. A full-size hygrometer (Panametrics) was used for testing and calibrating the Honeywell sensors. First the relative humidity of the air was measured. For the full calibration, a special gas-mixing setup was used, where relative humidity of the LST gas mixture could be varied from almost dry to almost fully saturated. With the sensor calibrated, a set of sensors was used to measure humidity vs. time in the LSTs. The sensors were placed in two sets of LST modules, one gas line flowing through each set. These modules were tested for count rate v. voltage while simultaneously measuring relative humidity in each module. One set produced expected readings, while the other showed the spike in count rate. The relative humidity in the two sets of modules looked very similar, but it rose significantly for modules further along the gas chain.

Development of a Simulation Toolkit for the Selection of High-Performance Systems for Office Buildings in Hot and Humid Climates (Phase I: Calibrated Simulation of the Case Study Building)  

E-Print Network (OSTI)

This paper reports on the development of an easy-to-use tool for the selection of high-performance systems in office buildings in hot and humid climates. In this paper, the preliminary results of a calibrated simulation of a typical large office building are presented for the John Connally building (124,000 sq-ft) in College Station, TX. To calibrate the DOE-2 simulation model, measured data were retrieved from permanently installed data loggers in the building, which measured whole-building electricity use and sub-metered cooling electricity use, lighting and miscellaneous equipment use, as well as thermal energy measurements for chilled water and hot water use. Also used in the calibration process were portable data loggers for comparing the performance of the building’s air-handling units with the simulated performance. For the calibration of the DOE-2 model, several calibration methodologies were used, including manual & iterative calibrations, graphical & statistical analysis, and signature analysis. This calibrated simulation model will be used as a base-case model for the development of a easy-to-use simulation tool for the selection of high-performance systems in office buildings in hot and humid climates. This paper presents the calibrated simulation results of the office building and outlines the additional steps for the development of the high-performance systems selection tool.

Approaches to 30% Energy Savings at the Community Scale in the Hot-Humid Climate  

Science Conference Proceedings (OSTI)

BA-PIRC has worked with several community-scale builders within the hot humid climate zone to improve performance of production, or community scale, housing. Tommy Williams Homes (Gainesville, FL), Lifestyle Homes (Melbourne, FL), and Habitat for Humanity (various locations, FL) have all been continuous partners of the BA Program and are the subjects of this report to document achievement of the Building America goal of 30% whole house energy savings packages adopted at the community scale. The scope of this report is to demonstrate achievement of these goals though the documentation of production-scale homes built cost-effectively at the community scale, and modeled to reduce whole-house energy use by 30% in the Hot Humid climate region. Key aspects of this research include determining how to evolve existing energy efficiency packages to produce replicable target savings, identifying what builders' technical assistance needs are for implementation and working with them to create sustainable quality assurance mechanisms, and documenting the commercial viability through neutral cost analysis and market acceptance. This report documents certain barriers builders overcame and the approaches they implemented in order to accomplish Building America (BA) Program goals that have not already been documented in previous reports.

Building for the Pacific Rim Countries. Energy-efficient building strategies for hot, humid climates  

DOE Green Energy (OSTI)

This book has been published by the Solar Energy Industries Association (SEIA), the US trade association of the solar thermal, photovoltaic, and passive solar manufacturers, distributors, and component suppliers. Its purpose is to help architects, builders, and developers construct energy-efficient homes in hot humid climates like the Pacific Rim Countries, and to allow occupants of these homes to enjoy enhanced comfort without reliance on mechanical air-conditioning systems. Two important factors are addressed in this book. First, the past few years have seen a tremendous increase in practical applications of new research. The current popularity of ceiling paddle fans, attic radiant barriers and natural daylighting attest to the importance of keeping up with the latest concepts in energy-reduction and comfort-awareness. Professionals who have been in the field for the past few years may be unaware of the latest research findings--some of which dramatically alter prior thinking on such subjects as natural ventilation or mechanical air conditioning. The second factor is the importance of site-specific characteristics, which greatly affect building strategies and designs. A thorough understanding of the climate is a prerequisite to good building design. Such factors as temperature, humidity, wind speed and direction, and solar radiation must be understood and properly integrated into the design for the home to be truly energy-efficient.

Modeling attic humidity as a function of weather, building construction, and ventilation rates  

Science Conference Proceedings (OSTI)

A dynamic model for predicting attic relative humidity (RH) and roof-sheathing moisture content (MC) was developed for microcomputer application. The model accepts standard hourly weather data and building-design parameters as input. Model predictions gave good agreement with measured data from a house located in Madison, Wisconsin. Solar radiation varies with roof orientation and plays an important role in determining moisture transfer to and from the roof sheathing. Opposing roof surfaces must be differentiated in attic humidity models to account for the effect of solar radiation. The model described in this paper is capable of such differentiation. Snow accumulation on a roof can significantly alter the temperature and moisture conditions in an attic, but further research is needed to understand the effect of a snow layer on attic temperatures. Various scenarios were simulated with this model to determine the effect of building practice and ventilation strategies on roof sheathing MC. Direct control of RH in the living space by ventilation is very effective in lowering attic moisture conditions. Where natural ventilation is not adequate, a timer-controlled attic fan shows great promise for ensuring efficient and economical attic ventilation.

Integrated Hygrothermal Performance of Building Envelopes and Systems in Hot and Humid Climates  

E-Print Network (OSTI)

In hot and humid climates the interior and exterior environmental loads that building envelopes must respond to are larger than many other climatic conditions. Moisture-originated failures in low-rise residential buildings have put a significant pressure to change construction codes in North America. Solutions to moisture induced problems may be difficult when several interacting mechanisms of moisture transport are present. A new approach to building envelope durability assessment has been introduced in North America; a moisture engineering approach. This requires system information about the wall systems as constructed along with aging characteristics coupled with advanced modeling that 0 term allow the designer to predict the Iong-term performances of building envelope systems. This permits the comparison and ranking of individual building envelope systems with respect to total hygrothermal performance. Critical information can be obtained by investigating the one to one relationships of a building envelope to interior and exterior environments, however, the total behavior of the actual whole building is not accounted for. This paper goes one step further, by incorporating the individual hygrothermal performances of all walls, roof, floor and mechanical systems. The direct and indirect coupling of the building envelope and indoor environment with HVAC system are included in the analysis. The full house hygrothermal performance of an aerated concrete wall system are examined for a hot and humid climate. The hour by hour drying potential of each system was then numerically analyzed using weather conditions of Miami (hot and humid climate). The results clearly demonstrate the limited drying potential for the wall system in that climate. Furthermore, the selected exterior thermal insulation strategies and interior vapor control strategies in this study clearly show the critical behavior of the full house with respect to drying initial construction moisture. The results show the importance of the total hygrothermal behavior of the whole house to the coupling between the various envelope parts, interior and exterior environments and HVAC system. From these results moisture control strategies are identified for the whole house hygrothermal performance.

PARAMETRIC STUDY OF GROUND SOURCE HEAT PUMP SYSTEM FOR HOT AND HUMID CLMATE  

DOE Green Energy (OSTI)

The U-tube sizes and varied thermal conductivity with different grout materials are studied based on the benchmark residential building in Hot-humid Pensacola, Florida. In this study, the benchmark building is metered and the data is used to validate the simulation model. And a list of comparative simulation cases with varied parameter value are simulated to study the importance of pipe size and grout to the ground source heat pump energy consumption. The simulation software TRNSYS [1] is employed to fulfill this task. The results show the preliminary energy saving based on varied parameters. Future work needs to be conducted for the cost analysis, include the installation cost from contractor and materials cost.

Exploring Cost-Effective, High Performance Residential Retrofits for Affordable Housing in the Hot Humid Climate  

E-Print Network (OSTI)

In 2009, a Department of Energy Building America team led by the Florida Solar Energy Center began working with partners to find cost-effective paths for improving the energy performance of existing homes in the hot humid climate. A test-in energy audit and energy use modeling of the partner’s proposed renovation package was performed for 41 affordable and middle income foreclosed homes in Florida and Alabama. HERS1 Indices ranged from 92 to 184 with modeled energy savings ranging from 3% to 50% (average of 26%). Analyses and recommendations were discussed with partners to encourage more efficient retrofits, highlight health and safety issues, and gather feedback on incremental cost of high performance measures. Ten completed renovations have modeled energy savings ranging from 9% to 48% (average 31%.) This paper presents the project’s process including our findings thus far and highlights of the first home to meet the target HERS Index of 70.

EFFECT OF HUMIDITY LEVEL ON THE CREEP PROPERTIES OF ALLOY 903 AT 650 C  

Science Conference Proceedings (OSTI)

Alloy 903 (FeNiCo+Nb) is currently used for certain components in industrial gas turbines for low coefficient of thermal expansion applications. A variance in creep behavior for material quality control evaluations suggested a possible effect of moisture level on stress rupture properties. To investigate the role of water vapor on the creep properties of alloy 903, controlled laboratory experiments were conducted at 650 C with 0 to 100% relative humidity. The water content was controlled by flowing dry air through a water bath at a constant temperature. A significant decrease of lifetime was observed in the presence of water vapor, which is likely related to grain boundary embrittlement by the inward diffusion of hydrogen. The increase of the microstructure grain aspect ratio by different forging processes generally improved the rupture lifetime and elongation in air. However, all specimens had reduced lifetime in the presence of water vapor despite the microstructure grain aspect ratios.

Reducing Thermal Losses and Gains With Buried and Encapsulated Ducts in Hot-Humid Climates  

SciTech Connect

The Consortium for Advanced Residential Buildings (CARB) monitored three houses in Jacksonville, FL, to investigate the effectiveness of encapsulated and encapsulated/buried ducts in reducing thermal losses and gains from ductwork in unconditioned attics. Burying ductwork beneath loose-fill insulation has been identified as an effective method of reducing thermal losses and gains from ductwork in dry climates, but it is not applicable in humid climates where condensation may occur on the outside of the duct jacket. By encapsulating the ductwork in closed cell polyurethane foam (ccSPF) before burial beneath loose-fill mineral fiber insulation, the condensation potential may be reduced while increasing the R-value of the ductwork.

Thermal and lighting performance of toplighting systems in the hot and humid climate of Thailand  

E-Print Network (OSTI)

This study evaluated the potential of toplighting systems in the hot and humid tropics by using Bangkok, Thailand (latitude 13.7�°N) as a test location. The analysis tested both the thermal and lighting performance of three toplighting systems. Toplighting, designed for use in one-story buildings or on the top floor of taller buildings, yields a uniformly distributed light throughout a space. However, in lower latitude locations, where there is no heating period, heat gain is a critical design issue since it significantly affects the annual energy consumption of the building. Accordingly, the decision to use toplighting in these locations needs to be carefully examined before any design considerations occur. In this study, the thermal and lighting performance of three toplighting systems were compared. For the thermal performance, total cooling loads, heat gains and losses, and interior temperature were evaluated. The lighting performance parameters examined were daylight factor, illuminance level, light distribution, and uniformity. EnergyPlus was used as the thermal analysis tool, and RADIANCE, along with a physical scale model, was used as the lighting performance analysis tool. The sky conditions tested were overcast, clear sky, and intermediate sky. Results have shown that, for locations with hot and humid climates with variable sky conditions such as Bangkok, Thailand, the roof monitors perform better than the other two systems in terms of the thermal and lighting performance. With similar cooling loads, the roof monitor provides better illuminance uniformity than the skylights and lightscoops, with adequate illuminance level (at mostly higher than 500 lux).

Integration with other DOE organizations and programs would assure that the enforcement process properly considers the actual or potential safety significance of a violation when determining an appropriate enforcement sanction. Achieving a proactive contractor compliance assurance rather than a heavy enforcement hand, will require a foundation of cooperation and teamwork across DOE organizations. This handbook identifies the areas of interface for the DOE Enforcement Program and provides guidance on roles and responsibilities for the key DOE organizational areas. It complements DOE-HDBK-1087-95 and 1089-95.

An Experimental Evaluation of HVAC-Grade Carbon-Dioxide Sensors: Part 3, Humidity, Temperature, and Pressure Sensitivity Test Results  

Science Conference Proceedings (OSTI)

This is the third paper in a four-part series reporting on the test and evaluation of typical carbon-dioxide sensors used in building HVAC applications. Fifteen models of NDIR HVAC-grade CO2 sensors were tested and evaluated to determine the humidity, temperature, and pressure sensitivity of the sensors. This paper reports the performance of the sensors at various relative humidity, temperature, and pressure levels common to building HVAC applications and provides a comparison with manufacturer specifications. Among the 15 models tested, eight models have a single-lamp, single-wavelength configuration, four models have a dual-lamp, single-wavelength configuration, and three models have a single-lamp, dual-wavelength configuration. The sensors were tested in a chamber specifically fabricated for this research. A description of the apparatus and the method of test are described in Part 1 (Shrestha and Maxwell 2009). The test result showed a wide variation in humidity, temperature, and pressure sensitivity of CO2 sensors among manufacturers. In some cases, significant variations in sensor performance exist between sensors of the same model. Even the natural variation in relative humidity could significantly vary readings of some CO2 sensor readings. The effects of temperature and pressure variation on NDIR CO2 sensors are unavoidable without an algorithm to compensate for the changes. For the range of temperature and pressure variation in an air-conditioned space, the effect of pressure variation is more significant compared to the effect of temperature variation.

Natural phenomena hazards assessment criteria for DOE sites: DOE Standard DOE-STD-1023-95  

Science Conference Proceedings (OSTI)

This paper summarizes hazard assessment criteria (DOE-STD-1023-95) for Natural Phenomena Hazards (NPH) at DOE sites. The DOE has established policy and requirements for NPH mitigation for DOE sites and facilities using a graded approach by DOE Order 5480.28. The graded approach is implemented by five performance categories established for structures, systems, and components (SSCs) at DOE facilities based on criteria provided by DOE-STD-1021-93. In applying the design/evaluation criteria of DOE-STD-1020-94 for DOE facilities subjected to one of the natural phenomena hazards, the establishment of design basis load levels consistent with the corresponding performance category is required. This standard provides general criteria as well as specific criteria for natural phenomena hazard assessments to ensure that adequate design basis load levels are established for design and/or evaluation of DOE facilities.

Improving Comfort in Hot-Humid Climates with a Whole-House Dehumidifier, Windermere, Florida (Fact Sheet)  

SciTech Connect

Maintaining comfort in a home can be challenging in hot-humid climates. At the common summer temperature set point of 75 degrees F, the perceived air temperature can vary by 11 degrees F because higher indoor humidity reduces comfort. Often the air conditioner (AC) thermostat set point is lower than the desirable cooling level to try to increase moisture removal so that the interior air is not humid or "muggy." However, this method is not always effective in maintaining indoor relative humidity (RH) or comfort. In order to quantify the performance of a combined whole-house dehumidifier (WHD) AC system, researchers from the U.S. Department of Energy's Building America team Consortium of Advanced Residential Buildings (CARB) monitored the operation of two Lennox AC systems coupled with a Honeywell DH150 TrueDRY whole-house dehumidifier for a six-month period. By using a WHD to control moisture levels (latent cooling) and optimizing a central AC to control temperature (sensible cooling), improvements in comfort can be achieved while reducing utility costs. Indoor comfort for this study was defined as maintaining indoor conditions at below 60% RH and a humidity ratio of 0.012 lbm/lbm while at common dry bulb set point temperatures of 74 degrees -80 degrees F. In addition to enhanced comfort, controlling moisture to these levels can reduce the risk of other potential issues such as mold growth, pests, and building component degradation. Because a standard AC must also reduce dry bulb air temperature in order to remove moisture, a WHD is typically needed to support these latent loads when sensible heat removal is not desired.

Methodology for the Preliminary Design of High Performance Schools in Hot and Humid Climates  

E-Print Network (OSTI)

A methodology to develop an easy-to-use toolkit for the preliminary design of high performance schools in hot and humid climates was presented. The toolkit proposed in this research will allow decision makers without simulation knowledge easily to evaluate accurately energy efficient measures for K-5 schools, which would contribute to the accelerated dissemination of energy efficient design. For the development of the toolkit, first, a survey was performed to identify high performance measures available today being implemented in new K-5 school buildings. Then an existing case-study school building in a hot and humid climate was selected and analyzed to understand the energy use pattern in a school building and to be used in developing a calibrated simulation. Based on the information from the previous step, an as-built and calibrated simulation was then developed. To accomplish this, five calibration steps were performed to match the simulation results with the measured energy use. The five steps include: 1) Using an actual 2006 weather file with measured solar radiation, 2) Modifying lighting & equipment schedule using ASHRAE’s RP-1093iv methods, 3) Using actual equipment performance curves (i.e., scroll chiller), 4) Using the Winkelmann’s method for the underground floor heat transfer, and 5) Modifying the HVAC and room setpoint temperature based on the measured field data. Next, the calibrated simulation of the case-study K-5 school was compared to an ASHRAE Standard 90.1-1999 code-compliant school. In the next step, the energy savings potentials from the application of several high performance measures to an equivalent ASHRAE Standard 90.1-1999 codecompliant school. The high performance measures applied included the recommendations from the ASHRAE Advanced Energy Design Guides (AEDG) for K-12 and other high performance measures from the literature review as well as a daylighting strategy and solar PV and thermal systems. The results show that the net energy consumption of the final high performance school with the solar thermal and a solar PV system would be 1,162.1 MMBtu, which corresponds to the 14.9 kBtu/sqft-yr of EUI. The calculated final energy and cost savings over the code compliant school are 68.2% and 69.9%, respectively. As a final step of the research, specifications for a simplified easy-to-use toolkit were then developed, and a prototype screenshot of the toolkit was developed. The toolkit is expected to be used by non-technical decision-maker to select and evaluate high performance measures for a new school building in terms of energy and cost savings in a quick and easy way.

Methodology for the Preliminary Design of High Performance Schools in Hot and Humid Climates  

E-Print Network (OSTI)

A methodology to develop an easy-to-use toolkit for the preliminary design of high performance schools in hot and humid climates was presented. The toolkit proposed in this research will allow decision makers without simulation knowledge easily to evaluate accurately energy efficient measures for K-5 schools, which would contribute to the accelerated dissemination of energy efficient design. For the development of the toolkit, first, a survey was performed to identify high performance measures available today being implemented in new K-5 school buildings. Then an existing case-study school building in a hot and humid climate was selected and analyzed to understand the energy use pattern in a school building and to be used in developing a calibrated simulation. Based on the information from the previous step, an as-built and calibrated simulation was then developed. To accomplish this, five calibration steps were performed to match the simulation results with the measured energy use. The five steps include: 1) Using an actual 2006 weather file with measured solar radiation, 2) Modifying lighting & equipment schedule using ASHRAE's RP-1093 methods, 3) Using actual equipment performance curves (i.e., scroll chiller), 4) Using the Winkelmann's method for the underground floor heat transfer, and 5) Modifying the HVAC and room setpoint temperature based on the measured field data. Next, the calibrated simulation of the case-study K-5 school was compared to an ASHRAE Standard 90.1-1999 code-compliant school. In the next step, the energy savings potentials from the application of several high performance measures to an equivalent ASHRAE Standard 90.1-1999 codecompliant school.

Theory, electro-optical design, testing, and calibration of a prototype atmospheric supersaturation, humidity, and temperature sensor. Final report Mar 81-Jul 82  

SciTech Connect

A new infrared differential absorption - passive thermal emission based instrument designed to make accurate in-cloud measurements of absolute humidity, air temperature, relative humidity, and ice and water supersaturations has been developed. Absolute humidity is measured by the differential infrared absorption of a broad-band light beam between 2.45 microns wavelength and the strongly absorbing water vapor band at 2.67 microns. Air temperature is sensed by a passive radiometric measurement of the Planck's law radiance emitted by carbon dioxide molecules in their very intense emission band at 4.25 microns. Significant operational advantages over previous 14-16 micron band radiometers are achieved. These non-contact optical measurements of absolute humidity and true air temperature can then be combined to yield relative humidity values with respect to both water and ice which remain valid in condensing supersaturated conditions and in spite of hydrometeors in the sample volume.

Microcomputer Energy Analysis Studies of Selected Building Types in a Hot, Humid Climatic Zone  

E-Print Network (OSTI)

The DOE-2 building energy analysis computer program has been used in both the design and analysis of new or retrofitted buildings. The combination of ease of use, economy, and the capability of producing a comprehensive thermal analysis has made this tool valuable to the design professional. Recent developments in the microcomputer area make it possible to employ hourly building energy analysis computer models, such a s DOE-2, that were once available only through use of mainframe computers, A microcomputer version of the DOE-2 model is currently available for the study of design and analysis simulations of many building types. Several characteristic buildings emphasizing variations in housing, office/commercial, and school types are being studied. These building types form typical low-scale buildings that are found throughout the region. The discovery of the effects of shape, orientation , mass, and other architectonic elements on energy conservation form a major concern of the survey. A DOE-2 program version adapted for use on a microcomputer demonstrating similar modeling capabilities to the mainframe version is the primary analytical tool used in this study. DOE-2 simulates the heating and cooling loads and the energy consumed by both the primary plant and secondary HVAC energy sources.

Best Practice Upgrades for New Energy Efficient Homes in Hot and Humid Climates  

E-Print Network (OSTI)

The EPA's ENERGY STAR Homes program is a national voluntary program that promotes the construction of new homes that are 30% more efficient than the Model Energy Code. Accordingly, with the Home Energy Rating System (HERS) scoring system, ENERGY STAR Homes must achieve a score of at least an 86. This performance-based compliance requirement enables builders to be creative in the specific energy efficiency features that they build in their new homes. However, builders often want to know what the minimum energy efficiency features of an ENERGY STAR Home would likely be - before they joined the program. To solve this problem, EPA developed the Builder Option Packages (BOPs). BOPS are currently used as marketing tools to communicate the typical energy efficiency features of ENERGY STAR Homes. This paper will focus on the hot and humid portion of the US. and explain the technical methodology used to develop the BOPS as well as the energy use and HERS scores obtained for the various configurations analyzed.

Enthalpy Wheels Come of Age: Applying Energy Recovery Ventilation to Hospitality Venues in Hot, Humid Climate  

E-Print Network (OSTI)

Energy recovery ventilation systems, including rotary heat exchangers or enthalpy wheels, utilize mature technologies that are routinely applied in commercial buildings. Energy recovery is particularly important in buildings with significant outdoor air intake requirements and has recently become widely accepted in applications such as schools and theatres. Hospitality applications including restaurants, bars, casinos and similar settings also stand to benefit from application of the technology, however, there is a lack of experience and therefore of accepted guidance in these applications. Furthermore, the unique challenges inherent in the variety of hospitality venues may limit appropriate use of the technology. Applying energy recovery ventilation to hospitality venues in hot, humid climates need not be complex. This paper proposes guidelines that can facilitate application of the technology by specifiers or other construction professionals. These guidelines address evaluation of typical projects for the suitability of energy recovery, selection of appropriate energy recovery ventilation technology, and criteria for successful application of enthalpy wheels. Examples of applications developed for different mechanical systems and building types are provided. The literature describing the opportunities and limitations associated with enthalpy wheels is summarized and referenced. Installation, operation, and maintenance insights are presented, derived from the body of industry experience with enthalpy wheels.
