Field Evaluation of Programmable Thermostats  

SciTech Connect

Prior research suggests that poor programmable thermostats usability may prevent their effective use to save energy. We hypothesized that home occupants with a high-usability thermostats would be more likely to use them to save energy than people with a basic thermostat. We randomly installed a high-usability thermostat in half the 77 apartments of an affordable housing complex, installing a basic thermostat in the other half. During the heating season, we collected space temperature and furnace on-off data to evaluate occupant interaction with the thermostats, foremost nighttime setbacks. We found that thermostat usability did not influence energy-saving behaviors, finding no significant difference in temperature maintained among apartments with high- and low-usability thermostats.

Improved roof stabilization technologies  

SciTech Connect

Decontamination and decommissioning (D and D) activities require that personnel have access to all areas of structures, some of which are more than 40 years old. In many cases, these structures have remained in a standby condition for up to 10 years; few preventative maintenance activities have been performed on them because of lack of funding or a defined future plan of action. This situation has led to deteriorated building conditions, resulting in potential personnel safety hazards. In addition, leaky roofs allow water to enter the buildings, which can cause the spread of contamination and increase building deterioration, worsening the already unsafe working conditions. To ensure worker safety and facilitate building dismantlement, the assessment of roof stabilization techniques applicable to US Department of Energy (DOE) structures has become an important issue. During Fiscal year 1997 (FY97), a comprehensive reliability-based model for the structural stabilization analysis of roof system in complex structures was developed. The model consists of three major components: a material testing method, a deterministic structural computer model, and a reliability-based optimization, and probabilistic analyses of roof structures can be implemented. Given site-specific needs, this model recommends the most appropriate roof stabilization system. This model will give not only an accurate evaluation of the existing roof system in complex structures, but it will also be a reliable method to aid the decision-making process. This final report includes in its appendix a Users` Manual for the Program of Deterministic and Reliability Analysis of Roof Structures.

Energy, Carbon-emission and Financial Savings from Thermostat Control  

SciTech Connect

Among the easiest approaches to energy, and cost, savings for most people is the adjustment of thermostats to save energy. Here we estimate savings of energy, carbon, and money in the United States of America (USA) that would result from adjusting thermostats in residential and commercial buildings by about half a degree Celsius downward during the heating season and upward during the cooling season. To obtain as small a unit as possible, and therefore the least likely to be noticeable by most people, we selected an adjustment of one degree Fahrenheit (0.56 degree Celsius) which is the gradation used almost exclusively on thermostats in the USA and is the smallest unit of temperature that has been used historically. Heating and/or cooling of interior building space for personal comfort is sometimes referred to as space conditioning, a term we will use for convenience throughout this work without consideration of humidity. Thermostat adjustment, as we use the term here, applies to thermostats that control the indoor temperature, and not to other thermostats such as those on water heaters. We track emissions of carbon only, rather than of carbon dioxide, because carbon atoms change atomic partners as they move through the carbon cycle, from atmosphere to biosphere or ocean and, on longer time scales, through the rock cycle. To convert a mass of carbon to an equivalent mass of carbon dioxide (thereby including the mass of the 2 oxygen atoms in each molecule) simply multiply by 3.67.

The offices with windows that faced south and west were hottest, while offices with windows facing north and east were cooler-and the offices without windows were, on average, about as comfortable as your refrigerator.

Three dynamical methods for computing canonical-ensemble Helmholtz free energies are discussed and compared for a thermostatted six-body harmonic chain. We use a Martyna-Klein-Tuckerman thermostat [J. Chem. Phys. 97, 2635 (1992)] with six time-reversible friction coefficients to study both single-trajectory and ensemble-averaged free-energy changes. Though all three dynamic methods produce identical long-time averages, the one based on Kirkwoods coupling-parameter theory [J. Chem. Phys. 3, 300 (1935)] converges much more rapidly than do the two based on time-integrated heat transfer.

Advanced Energy Efficient Roof System  

SciTech Connect

Energy consumption in buildings represents 40 percent of primary U.S. energy consumption, split almost equally between residential (22%) and commercial (18%) buildings.1 Space heating (31%) and cooling (12%) account for approximately 9 quadrillion Btu. Improvements in the building envelope can have a significant impact on reducing energy consumption. Thermal losses (or gains) from the roof make up 14 percent of the building component energy load. Infiltration through the building envelope, including the roof, accounts for an additional 28 percent of the heating loads and 16 percent of the cooling loads. These figures provide a strong incentive to develop and implement more energy efficient roof systems. The roof is perhaps the most challenging component of the building envelope to change for many reasons. The engineered roof truss, which has been around since 1956, is relatively low cost and is the industry standard. The roof has multiple functions. A typical wood frame home lasts a long time. Building codes vary across the country. Customer and trade acceptance of new building products and materials may impede market penetration. The energy savings of a new roof system must be balanced with other requirements such as first and life-cycle costs, durability, appearance, and ease of construction. Conventional residential roof construction utilizes closely spaced roof trusses supporting a layer of sheathing and roofing materials. Gypsum board is typically attached to the lower chord of the trusses forming the finished ceiling for the occupied space. Often in warmer climates, the HVAC system and ducts are placed in the unconditioned and otherwise unusable attic. High temperature differentials and leaky ducts result in thermal losses. Penetrations through the ceilings are notoriously difficult to seal and lead to moisture and air infiltration. These issues all contribute to greater energy use and have led builders to consider construction of a conditioned attic. The options considered to date are not ideal. One approach is to insulate between the trusses at the roof plane. The construction process is time consuming and costs more than conventional attic construction. Moreover, the problems of air infiltration and thermal bridges across the insulation remain. Another approach is to use structurally insulated panels (SIPs), but conventional SIPs are unlikely to be the ultimate solution because an additional underlying support structure is required except for short spans. In addition, wood spline and metal locking joints can result in thermal bridges and gaps in the foam. This study undertook a more innovative approach to roof construction. The goal was to design and evaluate a modular energy efficient panelized roof system with the following attributes: (1) a conditioned and clear attic space for HVAC equipment and additional finished area in the attic; (2) manufactured panels that provide structure, insulation, and accommodate a variety of roofing materials; (3) panels that require support only at the ends; (4) optimal energy performance by minimizing thermal bridging and air infiltration; (5) minimal risk of moisture problems; (6) minimum 50-year life; (7) applicable to a range of house styles, climates and conditions; (8) easy erection in the field; (9) the option to incorporate factory-installed solar systems into the panel; and (10) lowest possible cost. A nationwide market study shows there is a defined market opportunity for such a panelized roof system with production and semi-custom builders in the United States. Senior personnel at top builders expressed interest in the performance attributes and indicate long-term opportunity exists if the system can deliver a clear value proposition. Specifically, builders are interested in (1) reducing construction cycle time (cost) and (2) offering increased energy efficiency to the homebuyer. Additional living space under the roof panels is another low-cost asset identified as part of the study. The market potential is enhanced through construction activity levels in target marke

Evaluation of Roof Bolting Requirements Based on In-Mine Roof Bolter Drilling  

SciTech Connect

Roof bolting is the most popular method for underground openings in the mining industry, especially in the bedded deposits such as coal. In fact, all U.S. underground coal mine entries are roof-bolted as required by law. However, roof falls still occur frequently in the roof bolted entries. The two possible reasons are: the lack of knowledge of and technology to detect the roof geological conditions in advance of mining, and lack of roof bolting design criteria for modern roof bolting systems. This research is to develop a method for predicting the roof geology and stability condition in real time during roof bolting operation. Based on this information, roof bolting design criteria for modern roof bolting systems will be developed for implementation in real time. For the prediction of roof geology and stability condition in real time, a micro processor was used and a program developed to monitor and record the drilling parameters of roof bolter. These parameters include feed pressure, feed flow (penetration rate), rotation pressure, rotation rate, vacuum pressure, oil temperature of hydraulic circuit, and signals for controlling machine. From the results of a series of laboratory and underground tests so far, feed pressure is found to be a good indicator for identifying the voids/fractures and estimating the roof rock strength. The method for determining quantitatively the location and the size of void/fracture and estimating the roof rock strength from the drilling parameters of roof bolter was developed. Also, a set of computational rules has been developed for in-mine roof using measured roof drilling parameters and implemented in MRGIS (Mine Roof Geology Information System), a software package developed to allow mine engineers to make use of the large amount of roof drilling parameters for predicting roof geology properties automatically. For the development of roof bolting criteria, finite element models were developed for tensioned and fully grouted bolting designs. Numerical simulations were performed to investigate the mechanisms of modern roof bolting systems including both the tension and fully grouted bolts. Parameters to be studied are: bolt length, bolt spacing, bolt size/strength, grout annulus, in-situ stress condition, overburden depth, and roof geology (massive strata, fractured, and laminated or thinly-bedded). Based on the analysis of the mechanisms of both bolting systems and failure modes of the bolted strata, roof bolting design criteria and programs for modern roof bolting systems were developed. These criterion and/or programs were combined with the MRGIS for use in conjunction with roof bolt installation.

Consider the results from a Lawrence Berkeley National Laboratory study in Austin, Texas, which measured a dark roof to average a whopping 43 degrees hotter than a light roof. The hotter the roof, the hotter the building becomes, and the more air-conditioning is needed - 11 percent, in that particular study. That in turn puts more carbon dioxide into the atmosphere.

Global cooling updates: Reflective roofs and pavements  

Science Journals Connector (OSTI)

With increasing the solar reflectance of urban surfaces, the outflow of short-wave solar radiation increases, less solar heat energy is absorbed leading to lower surface temperatures and reduced outflow of thermal radiation into the atmosphere. This process of negative radiative forcing effectively counters global warming. Cool roofs also reduce cooling-energy use in air conditioned buildings and increase comfort in unconditioned buildings; and cool roofs and cool pavements mitigate summer urban heat islands, improving outdoor air quality and comfort. Installing cool roofs and cool pavements in cities worldwide is a compelling winwinwin activity that can be undertaken immediately, outside of international negotiations to cap CO2 emissions. We review the status of cool roof and cool pavements technologies, policies, and programs in the U.S., Europe, and Asia. We propose an international campaign to use solar reflective materials when roofs and pavements are built or resurfaced in temperate and tropical regions.

February on the east coast has been like a roller coaster ride, with temperatures plunging one day, then warm enough the next to skip the coat. In my home, I've spent the month trying to predict the ups and downs of the weather by adjusting my heater constantly. It's tempting to leave the thermostat on at a set temperature, so that the room is warm when returning home. Many assume this saves energy, because the heater won't have to work as hard to heat the room to the desired

Green Roofs Green Roofs New and Underutilized Technology: Green Roofs October 8, 2013 - 2:53pm Addthis The following information outlines key deployment considerations for green roofs within the Federal sector. Benefits Green roofs place vegetation on the rooftop to reduce heat load and add insulation. It also reduces storm runoff from the roof. Application Green roofs are appropriate for deployment within most building categories with higher roof to conditioned floor area ratios and should be considered in building design, renovation, or during roof replacement projects. Climate and Regional Considerations Climate issues can affect the performance of green roofs. Key Factors for Deployment Green roofs have weight loading issues, which need to be considered prior to deployment.

Next Generation Roofs and Attics for Homes  

SciTech Connect

Prototype residential roof and attic assemblies were constructed and field tested in a mixed-humid U.S. climate. Summer field data showed that at peak day irradiance the heat transfer penetrating the roof deck dropped almost 90% compared with heat transfer for a conventional roof and attic assembly. The prototype assemblies use a combination of strategies: infrared reflective cool roofs, radiant barriers, above-sheathing ventilation, low-emittance surfaces, insulation, and thermal mass to reduce the attic air temperature and thus the heat transfer into the home. The prototype assemblies exhibited attic air temperatures that did not exceed the peak day outdoor air temperature. Field results were benchmarked against an attic computer tool and simulations made for the densely populated, hot and dry southeastern and central-basin regions of California. New construction in the central basin could realize a 12% drop in ceiling and air-conditioning annual load compared with a code-compliant roof and attic having solar reflectance of 0.25 and thermal emittance of 0.75. In the hot, dry southeastern region of California, the combined ceiling and duct annual load drops by 23% of that computed for a code-compliant roof and attic assembly. Eliminating air leakage from ducts placed in unconditioned attics yielded savings comparable to the best simulated roof and attic systems. Retrofitting an infrared reflective clay tile roof with 1 -in (0.032-m) of EPS foam above the sheathing and improving existing ductwork by reducing air leakage and wrapping ducts with insulation can yield annual savings of about $200 compared with energy costs for pre-1980 construction.

Dark roofs can be 50 degrees hotter than light roofs. Combined with dark roads and parking lots, dark roofs lead to the 'urban heat island' effect: cities tend to be 2-5 degrees hotter. A cooler roof means energy bills that are up to 10-15% lower because your air conditioner doesn't have to work as hard. Check out Google Earth - the 'view from above' of your favorite American city. And look at the roofs of the office buildings, warehouses, shopping centers, and even the homes. Most of them are probably pretty dark in color - and this means they heat up a lot when the weather is warm -

Dark-colored roofs and roadways create what is called the "urban heat island effect," meaning a city is significantly warmer than its surrounding rural areas. Light colored roofs reduce the heat island effect and improve air quality by reducing emissions. Lighter-colored roofing surfaces reflect more of the sun's heat, which helps to improve building efficiency by reducing cooling costs and offsetting carbon emissions.

Application of Spray Foam Insulation Under Plywood and OSB Roof Sheathing (Fact Sheet)  

SciTech Connect

Spray polyurethane foams (SPFs) have advantages over alternative insulation methods because they provide air sealing in complex assemblies, particularly roofs. Spray foam can provide the thermal, air, and vapor control layers in both new and retrofit construction. Unvented roof strategies with open cell and closed cell SPF insulation sprayed to the underside of roof sheathing have been used since the mid-1990s to provide durable and efficient building enclosures. However, there have been isolated incidents of failures (either sheathing rot or SPF delamination) that raise some general concerns about the hygrothermal performance and durability of these systems. The primary risks for roof systems are rainwater leaks, condensation from diffusion and air leakage, and built-in construction moisture. This project directly investigated rain and indirectly investigated built-in construction moisture and vapor drives. Research involved both hygrothermal modeling of a range of rain water leakage scenarios and field evaluations of in-service residential roofs. Other variables considered were climate zone, orientation, interior relative humidity, and the vapor permeance of the coating applied to the interior face of open cell SPF.

Geologic factors in coal mines roof stability: a progress report  

SciTech Connect

This report summarizes 10 selected United States Bureau of Mines research contract reports produced from 1970 to 1980 that consist largely of geologic studies of coal-mine roof-support problems. The reports focus on the Appalachian and Illinois coal-mining regions. In the Appalachian region two geologic structures, roof rolls and slickensides, predominate as features that directly contribute to roof falls. Studies of these and other structures are reviewed, and improved methods of utilizing drill core and core logs to prepare hazard maps are presented.

Probabilistic prediction of green roof energy performance under parameter uncertainty  

Science Journals Connector (OSTI)

Abstract Studies on the quantification of energy benefits of a green roof have so far treated its parameter values only deterministically. In reality, however, these values may scatter over different ranges due to the inherent variation of vegetation and soil properties and also because of the unavoidable deviation from designated values during construction and/or actual operation of a green roof. Under such parameter uncertainty, green roof performance can no longer be predicted deterministically but rather probabilistically. The present study attempts to integrate the whole building energy simulation with a parametric uncertainty analysis. An example office building is used to systematically examine how the cooling and heating energy demands can be reduced by a green roof that replaces a conventional roof, when values of the most significant green roof parameters determined by sensitivity analysis are treated as random variables with prescribed probability distributions. An ensemble of green roof configurations is generated using Monte Carlo simulation with a Latin hypercube sampling technique. The coefficient of variation of the calculated energy savings is found almost linearly related to (with a slope of about 0.4) that of green roof parameters. Finally, implications of probabilistic energy analysis for more reliable green roof design are emphasized.

Reflective 'cool' roofs under aerosol-burdened skies: radiative benefits across selected Indian cities  

Science Journals Connector (OSTI)

The use of reflective surfaces offers one low-cost solution for reducing solar loading to urban environments and the Earth that should be considered as part of sustainable urban design. Here, we characterize the radiative benefits, i.e. the additional shortwave radiation leaving the atmosphere, from the installation of highly reflective 'cool' roofs in urban areas in India that face relatively large local aerosol burdens. We use a previously tested column radiative transfer model to estimate the energy per unit area reflected to space from increasing the surface albedo at six cities within India. The model is used to characterize radiative transfer each day over five years (20082012) based on mid-day satellite retrievals of MODIS aerosol depth, cloud water path, and average surface albedo and MERRA atmospheric profiles of temperature and composition. Compared against ten months of field observations in two cities, the model derived incoming surface shortwave radiation estimates relative to observations show small biases (0.5% and ?2.6%, at Pantnagar and Nainital, respectively). Despite the high levels of local aerosols we found cool roofs provided significant radiative benefits at all locations. Averaged over the five year period we found that increasing the albedo of 1 m2 of roof area by 0.5 would reflect to space 0.91.2 kWh daily from 08:3015:30 LST, depending on location. This is equivalent to a constant forcing of 3750 W m?2 (equivalent to reducing CO2 emissions by 74 to 101 kg CO2 m?2 roof area). Last, we identify a co-benefit of improving air quality, in that removing aerosols from the atmosphere could increase the radiative benefits from cool roofs by 2374%, with the largest potential increase found at Delhi and the smallest change found at Nainital.

Effectiveness of Cool Roof Coatings with Ceramic Particles  

SciTech Connect

Liquid applied coatings promoted as cool roof coatings, including several with ceramic particles, were tested at Oak Ridge National Laboratory (ORNL), Oak Ridge, Tenn., for the purpose of quantifying their thermal performances. Solar reflectance measurements were made for new samples and aged samples using a portable reflectometer (ASTM C1549, Standard Test Method for Determination of Solar Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer) and for new samples using the integrating spheres method (ASTM E903, Standard Test Method for Solar Absorptance, Reflectance, and Transmittance of Materials Using Integrating Spheres). Thermal emittance was measured for the new samples using a portable emissometer (ASTM C1371, Standard Test Method for Determination of Emittance of Materials Near Room 1 Proceedings of the 2011 International Roofing Symposium Temperature Using Portable Emissometers). Thermal conductivity of the coatings was measured using a FOX 304 heat flow meter (ASTM C518, Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus). The surface properties of the cool roof coatings had higher solar reflectance than the reference black and white material, but there were no significant differences among coatings with and without ceramics. The coatings were applied to EPDM (ethylene propylene diene monomer) membranes and installed on the Roof Thermal Research Apparatus (RTRA), an instrumented facility at ORNL for testing roofs. Roof temperatures and heat flux through the roof were obtained for a year of exposure in east Tennessee. The field tests showed significant reduction in cooling required compared with the black reference roof (~80 percent) and a modest reduction in cooling compared with the white reference roof (~33 percent). The coating material with the highest solar reflectivity (no ceramic particles) demonstrated the best overall thermal performance (combination of reducing the cooling load cost and not incurring a large heating penalty cost) and suggests solar reflectivity is the significant characteristic for selecting cool roof coatings.

Development and Validation of Aggregated Models for Thermostatic Controlled Loads with Demand Response  

SciTech Connect

Demand response is playing an increasingly important role in smart grid research and technologies being examined in recently undertaken demonstration projects. The behavior of load as it is affected by various load control strategies is important to understanding the degree to which different classes of end-use load can contribute to demand response programs at various times. This paper focuses on developing aggregated control models for a population of thermostatically controlled loads. The effects of demand response on the load population dynamics are investigated.

Small Business Demand Response with Communicating Thermostats: SMUD's Summer Solutions Research Pilot  

SciTech Connect

This report documents a field study of 78 small commercial customers in the Sacramento Municipal Utility District service territory who volunteered for an integrated energy-efficiency/demand-response (EE-DR) program in the summer of 2008. The original objective for the pilot was to provide a better understanding of demand response issues in the small commercial sector. Early findings justified a focus on offering small businesses (1) help with the energy efficiency of their buildings in exchange for occasional load shed, and (2) a portfolio of options to meet the needs of a diverse customer sector. To meet these expressed needs, the research pilot provided on-site energy efficiency advice and offered participants several program options, including the choice of either a dynamic rate or monthly payment for air-conditioning setpoint control. An analysis of hourly load data indicates that the offices and retail stores in our sample provided significant demand response, while the restaurants did not. Thermostat data provides further evidence that restaurants attempted to precool and reduce AC service during event hours, but were unable to because their air-conditioning units were undersized. On a 100 F reference day, load impacts of all participants during events averaged 14%, while load impacts of office and retail buildings (excluding restaurants) reached 20%. Overall, pilot participants including restaurants had 2007-2008 summer energy savings of 20% and bill savings of 30%. About 80% of participants said that the program met or surpassed their expectations, and three-quarters said they would probably or definitely participate again without the $120 participation incentive. These results provide evidence that energy efficiency programs, dynamic rates and load control programs can be used concurrently and effectively in the small business sector, and that communicating thermostats are a reliable tool for providing air-conditioning load shed and enhancing the ability of customers on dynamic rates to respond to intermittent price events.

Bad seeds sprout perilous dynamics: stochastic thermostat induced trajectory synchronization in biomolecules  

SciTech Connect

Molecular dynamics simulations starting from different initial conditions are commonly used to mimic the behavior of an experimental ensemble. We show in this article that when a Langevin thermostat is used to maintain constant temperature during such simulations, extreme care must be taken when choosing the random number seeds used in order to prevent statistical correlation among the MD trajectories. While recent studies have shown that stochastically thermostatted trajectories evolving within a single potential basin with identical random number seeds tend to synchronize, we show that there is a synchronization effect even for complex, biologically relevant systems. We demonstrate this effect in simulations of Alanine trimer and pentamer and in a simulation of a temperature-jump experiment for peptide folding of a 14-residue peptide. Even in replica-exchange simulations, in which the trajectories are at different temperatures, we find partial synchronization occurring when the same random number seed is employed. We explain this by extending the recent derivation of the synchronization effect for two trajectories in a harmonic well to the case in which the trajectories are at two different temperatures. Our results suggest several ways in which mishandling selection of a pseudo random number generator initial seed can lead to corruption of simulation data. Simulators can fall into this trap in simple situations such as neglecting to specifically indicate different random seeds in either parallel or sequential restart simulations, utilizing a simulation package with a weak pseudorandom number generator, or using an advanced simulation algorithm that hasn't been programmed to distribute initial seeds.

Comparison of Software Models for Energy Savings from Cool Roofs  

SciTech Connect

A web-based Roof Savings Calculator (RSC) has been deployed for the United States Department of Energy as an industry-consensus tool to help building owners, manufacturers, distributors, contractors and researchers easily run complex roof and attic simulations. This tool employs modern web technologies, usability design, and national average defaults as an interface to annual simulations of hour-by-hour, whole-building performance using the world-class simulation tools DOE-2.1E and AtticSim in order to provide estimated annual energy and cost savings. In addition to cool reflective roofs, RSC simulates multiple roof and attic configurations including different roof slopes, above sheathing ventilation, radiant barriers, low-emittance roof surfaces, duct location, duct leakage rates, multiple substrate types, and insulation levels. A base case and energy-efficient alternative can be compared side-by-side to estimate monthly energy. RSC was benchmarked against field data from demonstration homes in Ft. Irwin, California; while cooling savings were similar, heating penalty varied significantly across different simulation engines. RSC results reduce cool roofing cost-effectiveness thus mitigating expected economic incentives for this countermeasure to the urban heat island effect. This paper consolidates comparison of RSC s projected energy savings to other simulation engines including DOE-2.1E, AtticSim, Micropas, and EnergyPlus, and presents preliminary analyses. RSC s algorithms for capturing radiant heat transfer and duct interaction in the attic assembly are considered major contributing factors to increased cooling savings and heating penalties. Comparison to previous simulation-based studies, analysis on the force multiplier of RSC cooling savings and heating penalties, the role of radiative heat exchange in an attic assembly, and changes made for increased accuracy of the duct model are included.

Soiling of building envelope surfaces and its effect on solar reflectance - Part II: Development of an accelerate aging method for roofing materials  

SciTech Connect

Highly reflective roofs can decrease the energy required for building air conditioning, help mitigate the urban heat island effect, and slow global warming. However, these benefits are diminished by soiling and weathering processes that reduce the solar reflectance of most roofing materials. Soiling results from the deposition of atmospheric particulate matter and the growth of microorganisms, each of which absorb sunlight. Weathering of materials occurs with exposure to water, sunlight, and high temperatures. This study developed an accelerated aging method that incorporates features of soiling and weathering. The method sprays a calibrated aqueous soiling mixture of dust minerals, black carbon, humic acid, and salts onto preconditioned coupons of roofing materials, then subjects the soiled coupons to cycles of ultraviolet radiation, heat and water in a commercial weatherometer. Three soiling mixtures were optimized to reproduce the site-specific solar spectral reflectance features of roofing products exposed for 3 years in a hot and humid climate (Miami, Florida); a hot and dry climate (Phoenix, Arizona); and a polluted atmosphere in a temperate climate (Cleveland, Ohio). A fourth mixture was designed to reproduce the three-site average values of solar reflectance and thermal emittance attained after 3 years of natural exposure, which the Cool Roof Rating Council (CRRC) uses to rate roofing products sold in the US. This accelerated aging method was applied to 25 products?single ply membranes, factory and field applied coatings, tiles, modified bitumen cap sheets, and asphalt shingles?and reproduced in 3 days the CRRC's 3-year aged values of solar reflectance. This accelerated aging method can be used to speed the evaluation and rating of new cool roofing materials.

Cool roofs may also increase the need for heating energy in cold climates. For a commercial building, the decrease in annual cooling load is typically much greater than the increase in annual heating load. This study combines building energy simulations, local energy prices, local electricity emission factors, and local estimates of building density to characterize local, state average, and national average cooling energy savings, heating energy penalties, energy cost savings, and emission reductions per unit conditioned roof area. The annual heating and cooling energy uses of four commercial building prototypes-new office (1980+), old office (pre-1980), new retail (1980+), and old retail (pre-1980)-were simulated in 236 US cities. Substituting a weathered cool white roof (solar reflectance 0.55) for a weathered conventional gray roof (solar reflectance 0.20) yielded annually a cooling energy saving per unit conditioned roof area ranging from 3.30 kWh/m2 in Alaska to 7.69 kWh/m2 in Arizona (5.02 kWh/m2 nationwide); a heating energy penalty ranging from 0.003 therm/m2 in Hawaii to 0.14 therm/m2 in Wyoming (0.065 therm/m2 nationwide); and an energy cost saving ranging from $0.126/m2 in West Virginia to $1.14/m2 in Arizona ($0.356/m2 nationwide). It also offered annually a CO2 reduction ranging from 1.07 kg/m2 in Alaska to 4.97 kg/m2 in Hawaii (3.02 kg/m2 nationwide); an NOx reduction ranging from 1.70 g/m2 in New York to 11.7 g/m2 in Hawaii (4.81 g/m2 nationwide); an SO2 reduction ranging from 1.79 g/m2 in California to 26.1 g/m2 in Alabama (12.4 g/m2 nationwide); and an Hg reduction ranging from 1.08 μg/m2 in Alaska to 105 μg/m2 in Alabama (61.2 μg/m2 nationwide). Retrofitting 80% of the 2.58 billion square meters of commercial building conditioned roof area in the USA would yield an annual cooling energy saving of 10.4 TWh; an annual heating energy penalty of 133 million therms; and an annual energy cost saving of $735 million. It would also offer an annual CO2 reduction of 6.23 Mt, offsetting the annual CO2 emissions of 1.20 million typical cars or 25.4 typical peak power plants; an annual NOx reduction of 9.93 kt, offsetting the annual NOx emissions of 0.57 million cars or 65.7 peak power plants; an annual SO2 reduction of 25.6 kt, offsetting the annual SO2 emissions of 815 peak power plants; and an annual Hg reduction of 126 kg.

Top-of-atmosphere radiative cooling with white roofs: experimental Top-of-atmosphere radiative cooling with white roofs: experimental verification and model-based evaluation Title Top-of-atmosphere radiative cooling with white roofs: experimental verification and model-based evaluation Publication Type Journal Article Year of Publication 2012 Authors Salamanca, Francisco, Shaheen R. Tonse, Surabi Menon, Vishal Garg, Krishna P. Singh, Manish Naja, and Marc L. Fischer Journal Environmental Research Letters Volume 7 Issue 4 Abstract We evaluate differences in clear-sky upwelling shortwave radiation reaching the top of the atmosphere in response to increasing the albedo of roof surfaces in an area of India with moderately high aerosol loading. Treated (painted white) and untreated (unpainted) roofs on two buildings in northeast India were analyzed on five cloudless days using radiometric imagery from the IKONOS satellite. Comparison of a radiative transfer model (RRTMG) and radiometric satellite observations shows good agreement (R2 = 0.927). Results show a mean increase of ~50 W m-2 outgoing at the top of the atmosphere for each 0.1 increase of the albedo at the time of the observations and a strong dependence on atmospheric transmissivity.

Empirically Derived Strength of Residential Roof Structures for Solar Installations.  

SciTech Connect

Engineering certification for the installation of solar photovoltaic (PV) modules on wood roofs is often denied because existing wood roofs do not meet structural design codes. This work is intended to show that many roofs are actually sufficiently strong given the conservatism in codes, documented allowable strengths, roof structure system effects, and beam composite action produced by joist-sheathing interaction. This report provides results from a testing program to provide actual load carrying capacity of residential rooftops. The results reveal that the actual load carrying capacity of structural members and systems tested are significantly stronger than allowable loads provided by the International Residential Code (IRC 2009) and the national structural code found in Minimum Design Loads for Buildings and Other Structures (ASCE 7-10). Engineering analysis of residential rooftops typically ignores the system affects and beam composite action in determining rooftop stresses given a potential PV installation. This extreme conservatism combined with conservatism in codes and published allowable stress values for roof building materials (NDS 2012) lead to the perception that well built homes may not have adequate load bearing capacity to enable a rooftop PV installation. However, based on the test results presented in this report of residential rooftop structural systems, the actual load bearing capacity is several times higher than published values (NDS 2012).

Preliminary Analysis of Energy Consumption for Cool Roofing Measures  

SciTech Connect

The spread of cool roofing has been more than prolific over the last decade. Driven by public demand and by government initiatives cool roofing has been a recognized low cost method to reduce energy demand by reflecting sunlight away from structures and back in to the atmosphere. While much of the country can benefit from the use of cool coatings it remains to be seen whether the energy savings described are appropriate in cooler climates. By use of commonly available calculators one can analyze the potential energy savings based on environmental conditions and construction practices.

Reduced-Order Modeling of Aggregated Thermostatic Loads With Demand Response  

SciTech Connect

Demand Response is playing an increasingly important role in smart grid control strategies. Modeling the behavior of populations of appliances under demand response is especially important to evaluate the effectiveness of these demand response programs. In this paper, an aggregated model is proposed for a class of Thermostatically Controlled Loads (TCLs). The model efficiently includes statistical information of the population, systematically deals with heterogeneity, and accounts for a second-order effect necessary to accurately capture the transient dynamics in the collective response. However, an accurate characterization of the collective dynamics however requires the aggregate model to have a high state space dimension. Most of the existing model reduction techniques require the stability of the underlying system which does not hold for the proposed aggregated model. In this work, a novel model reduction approach is developed for the proposed aggregated model, which can significantly reduce its complexity with small performance loss. The original and the reducedorder aggregated models are validated against simulations of thousands of detailed building models using GridLAB-D, which is a realistic open source distribution simulation software.

Equilibrium thermal characteristics of a building integrated photovoltaic tiled roof  

SciTech Connect

Photovoltaic (PV) modules attain high temperatures when exposed to a combination of high radiation levels and elevated ambient temperatures. The temperature rise can be particularly problematic for fully building integrated PV (BIPV) roof tile systems if back ventilation is restricted. PV laminates could suffer yield degradation and accelerated aging in these conditions. This paper presents a laboratory based experimental investigation undertaken to determine the potential for high temperature operation in such a BIPV installation. This is achieved by ascertaining the dependence of the PV roof tile temperature on incident radiation and ambient temperature. A theory based correction was developed to account for the unrealistic sky temperature of the solar simulator used in the experiments. The particular PV roof tiles used are warranted up to an operational temperature of 85 C, anything above this temperature will void the warranty because of potential damage to the integrity of the encapsulation. As a guide for installers, a map of southern Europe has been generated indicating locations where excessive module temperatures might be expected and thus where installation is inadvisable. (author)

A Study of the Energy-Saving Potential of Metal Roofs Incorporating Dynamic Insulation Systems  

SciTech Connect

This article presents various metal roof configurations that were tested at Oak Ridge National Laboratory in Tennessee, U.S. between 2009 and 2013, and describes their potential for reducing the attic-generated space-conditioning loads. These roofs contained different combinations of phase-change material, rigid insulation, low emittance surface, and above-sheathing ventilation with standing-seam metal panels on top. These roofs were designed to be installed on existing roofs decks, or on top of asphalt shingles for retrofit construction. All the tested roofs showed the potential for substantial energy savings compared to an asphalt shingle roof, which was used as a control for comparison. The roofs were constructed on a series of adjacent attics separated at the gables using thick foam insulation. The attics were built on top of a conditioned room. All attics were vented at the soffit and ridge. The test roofs and attics were instrumented with an array of thermocouples. Heat flux transducers were installed in the roof deck and attic floor (ceiling) to measure the heat flows through the roof and between the attic and conditioned space below. Temperature and heat flux data were collected during the heating, cooling and swing seasons over a three-year period. Data from previous years of testing have been published. Here, data from the latest roof configurations being tested in year three of the project are presented. All test roofs were highly effective in reducing the heat flows through the roof and ceiling, and in reducing the diurnal attic-temperature fluctuations.

Asphalt Roofing Shingles Into Energy Project Summary Report  

SciTech Connect

Based on a widely cited September, 1999 report by the Vermont Agency of Natural Resources, nearly 11 million tons of asphalt roofing shingle wastes are produced in the United States each year. Recent data suggests that the total is made up of about 9.4 million tons from roofing tear-offs and about 1.6 million tons from manufacturing scrap. Developing beneficial uses for these materials would conserve natural resources, promote protection of the environment and strengthen the economy. This project explored the feasibility of using chipped asphalt shingle materials in cement manufacturing kilns and circulating fluidized bed (CFB) boilers. A method of enhancing the value of chipped shingle materials for use as fuel by removing certain fractions for use as substitute raw materials for the manufacture of new shingles was also explored. Procedures were developed to prevent asbestos containing materials from being processed at the chipping facilities, and the frequency of the occurrence of asbestos in residential roofing tear-off materials was evaluated. The economic feasibility of each potential use was evaluated based on experience gained during the project and on a review of the well established use of shingle materials in hot mix asphalt. This project demonstrated that chipped asphalt shingle materials can be suitable for use as fuel in circulating fluidized boilers and cement kilns. More experience would be necessary to determine the full benefits that could be derived and to discover long term effects, but no technical barriers to full scale commercial use of chipped asphalt shingle materials in these applications were discovered. While the technical feasibility of various options was demonstrated, only the use of asphalt shingle materials in hot mix asphalt applications is currently viable economically.

CAVERN ROOF STABILITY FOR NATURAL GAS STORAGE IN BEDDED SALT  

SciTech Connect

This report documents research performed to develop a new stress-based criterion for predicting the onset of damage in salt formations surrounding natural gas storage caverns. Laboratory tests were conducted to investigate the effects of shear stress, mean stress, pore pressure, temperature, and Lode angle on the strength and creep characteristics of salt. The laboratory test data were used in the development of the new criterion. The laboratory results indicate that the strength of salt strongly depends on the mean stress and Lode angle. The strength of the salt does not appear to be sensitive to temperature. Pore pressure effects were not readily apparent until a significant level of damage was induced and the permeability was increased to allow penetration of the liquid permeant. Utilizing the new criterion, numerical simulations were used to estimate the minimum allowable gas pressure for hypothetical storage caverns located in a bedded salt formation. The simulations performed illustrate the influence that cavern roof span, depth, roof salt thickness, shale thickness, and shale stiffness have on the allowable operating pressure range. Interestingly, comparison of predictions using the new criterion with that of a commonly used criterion indicate that lower minimum gas pressures may be allowed for caverns at shallow depths. However, as cavern depth is increased, less conservative estimates for minimum gas pressure were determined by the new criterion.

A guidebook for insulated low-slope roof systems. IEA Annex 19, Low-slope roof systems: International Energy Agency Energy Conservation in Buildings and Community Systems Programme  

SciTech Connect

Low-slope roof systems are common on commercial and industrial buildings and, to a lesser extent, on residential buildings. Although insulating materials have nearly always been a component of low-slope roofs, the amount of insulation used has increased in the past two decades because of escalation of heating and cooling costs and increased awareness of the need for energy conservation. As the amount of insulation has increased, the demand has intensified for design, installation, and maintenance information specifically for well-insulated roofs. Existing practices for design, installation, and maintenance of insulated roofs have evolved from experience. Typically, these practices feature compromises due to the different properties of materials making up a given roof system. Therefore, they should be examined from time to time to ensure that they are appropriate as new materials continue to enter the market and as the data base on existing systems expands. A primary purpose of this International Energy Agency (IEA) study is to assess current roofing insulation practices in the context of an accumulating data base on performance.

Prospects of green roof technology for energy and thermal benefits in buildings: Case of Jordan  

Science Journals Connector (OSTI)

Abstract Heat transfer has a substantial impact on thermal comfort for indoor architectural spaces, which is mainly dependent on building envelopes. Improving the quality of indoor spaces means applying a climate-conscious design that is very beneficial in decreasing energy consumption in buildings. In this paper, a study based on thermal calculations and computer simulation is conducted to demonstrate the thermal benefits on energy saving as an approach to increase energy efficiency through green roof technology. The study focuses on roof surfaces as they account for a large portion of the insulation impact on built environments. A comparison between regular roof and green roof technologies was conducted to explore the effect of green roof materials on thermal transmittance and eventually on energy consumption of HVAC systems in buildings.

Green roofing in a building has many advantages including absorbing rainwater, providing thermal insulation, enhancing the ecology, creating a peaceful retreat for people and animals, improving air quality and helping to offset the air temperature and heat island effect. The aim of this paper is to monitor energy saving in the residential buildings of Dubai after applying green roofing techniques. The paper also attempts to provide a thermal analysis after the application of green roofs. A villa in Dubai was chosen as a case study. With the aid of energy simulation software, namely DesignBuilder, as well as manual recording and calculations, the energy savings after applying the green roofing were detected. To that extent, the paper draws some recommendations with regard to the types of green roofing that should be used in these particular climatic conditions based on this real experiment that took place over a one year period.

Numerical evaluation of the thermal performances of roof-mounted radiant barriers  

E-Print Network (OSTI)

This paper deals with the thermal performances of roof-mounted radiant barriers. Using dynamic simulations of a mathematical model of a whole test cell including a radiant barrier installed between the roof top and the ceiling, the thermal performance of the roof is calculated. The mean method is more particularly used to assess the thermal resistance of the building component and lead to a value which is compared to the one obtained for a mass insulation product such as polyurethane foam. On a further stage, the thermal mathematical model is replaced by a thermo-aeraulic model which is used to evaluate the thermal resistance of the roof as a function of the airflow rate. The results shows a better performance of the roof in this new configuration, which is widely used in practice. Finally, the mathematical relation between the thermal resistance and the airflow rate is proposed.

However, there have been isolated moisture related incidents reported anecdotally that raise potential concerns about the overall hygrothermal performance of these systems. The incidents related to rainwater leakage and condensation concerns. Condensation concerns have been extensively studied by others and are not further discussed in this report. This project involved hygrothermal modeling of a range of rainwater leakage and field evaluations of in-service residential roofs using spray foam insulation. All of the roof assemblies modeled exhibited drying capacity to handle minor rainwater leakage. All field evaluation locations of in-service residential roofs had moisture contents well within the safe range for wood-based sheathing. Explorations of eleven in-service roof systems were completed. The exploration involved taking a sample of spray foam from the underside of the roof sheathing, exposing the sheathing, then taking a moisture content reading. All locations had moisture contents well within the safe range for wood-based sheathing. One full-roof failure was reviewed, as an industry partner was involved with replacing structurally failed roof sheathing. In this case the manufacturer's investigation report concluded that the spray foam was installed on wet OSB based on the observation that the spray foam did not adhere well to the substrate and the pore structure of the closed cell spray foam at the ccSPF/OSB interface was indicative of a wet substrate.

NREL: Learning - Solar Hot Water  

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

Hot Water Hot Water Photo of solar collectors on a roof for a solar hot water system. For solar hot water systems, flat-plate solar collectors are typically installed facing south on a rooftop. The shallow water of a lake is usually warmer than the deep water. That's because the sunlight can heat the lake bottom in the shallow areas, which in turn, heats the water. It's nature's way of solar water heating. The sun can be used in basically the same way to heat water used in buildings and swimming pools. Most solar water heating systems for buildings have two main parts: a solar collector and a storage tank. The most common collector is called a flat-plate collector. Mounted on the roof, it consists of a thin, flat, rectangular box with a transparent cover that faces the sun. Small tubes

Indirect Benefits (Increased Roof Life and HVAC Savings) from a Solar PV System at the San Jos Convention Center  

Energy.gov (U.S. Department of Energy (DOE))

The City of San Jos is considering the installation of a solar photovoltaic (PV) system on the roof of the San Jos Convention Center. The installation would be on a lower section of the roof covering approximately 21,000 ft2. To assist city staff in making a decision on the PV installation, the Department of Energy Tiger Team has investigated potential indirect benefits of installing a solar PV system on the Convention Center roof. The indirect benefits include potential increase in roof life, as well as potential reduced heating and cooling load in the building due to roof shading from the PV system.

Dynamic thermal simulation of a glass-covered semi-outdoor space with roof evaporative cooling  

Science Journals Connector (OSTI)

In the hot season solar radiation impinging on a glass roofing may overheat the underneath space to temperature values which may generate a high stress environment. To moderate the extreme microclimate which may occur in a glass covered semi-outdoor space, evaporative cooling to be applied to the glass roof is suggested. The analysis is performed under both the thermal and the energetic point of view, by accounting for the actual climate of the considered location. The results point out that roof evaporative cooling coupled with glass sheet high solar radiation absorptivity may offer an attractive way for the control of a semi-outdoor environment.

Advances in Measuring Solar Reflectance-or, Why That Roof isn't as Cool

Advances in Measuring Solar Reflectance-or, Why That Roof isn't as Cool Advances in Measuring Solar Reflectance-or, Why That Roof isn't as Cool as You Thought it Was Speaker(s): Ronnen Levinson Date: June 30, 2009 - 12:00pm Location: LBNL Bldg. 66 Auditorium Solar reflectance is often used to estimate the solar heat gain and rate the "coolness" of roofs and pavements. A solar reflectance property measured by two popular ASTM standard test methods (E903, C1549) can underestimate the peak solar heat gain of a spectrally selective "cool colored" surface by nearly 100 W m-2 because it assumes that sunlight contains an unrealistically high fraction of near-infrared (invisible) energy. Its use in building energy simulations can overestimate cool-roof annual energy savings by more than 20%. I define a new and simple solar

Assessment and management of roof fall risks in underground coal mines  

Science Journals Connector (OSTI)

Accidents caused by roof falls are commonly faced problems of underground coal mines. These accidents may have detrimental effects on workers in the form of injury, disability or fatality as well as mining company due to downtimes, interruptions in the mining operations, equipment breakdowns, etc. This study proposes a risk and decision analysis methodology for the assessment and management of risk associated with mine roof falls in underground coal mines. In the proposed methodology, risk assessment requires the determination of probabilities, possible consequences and cost of consequences. Then the risk is managed by the application of decision-making principles. The probabilities are determined by the analysis of 1141 roof fall data from 12 underground mines in the Appalachian region. The consequences are assessed based on the type of injuries observed after roof falls and the place of the mining activity. The cost of consequences is modeled by the so-called relative cost criterion. A decision analysis framework is developed in order to manage the evaluated risk for a single mine. Then this model is extended to a regional model for the management of the roof fall risks in the mines of whole Appalachia. The proposed model is illustrated with an example and it is found to be a powerful technique for coping with uncertainties and the management of roof fall risks.

Aerodynamic efficiency of smoke ventilators in light streets and shed-type roofs  

Science Journals Connector (OSTI)

Low-rise industrial buildings in continental Europe have usually no or very little window area in the sidewalls. To provide the necessary daylight, translucent surfaces are fitted in the roof. Well known examples are shed roofs or curved and shed-type light streets in flat roofs. For economic reasons smoke ventilators are then integrated into the light surfaces. This paper gives typical examples of smoke ventilators installed in shed roofs and in curved or shed-type light streets. The measurement of the aerodynamic free areas on full scale apparatus is not possible due to the large dimensions of the relevant roof surfaces. Therefore, tests have to be conducted in model scale. The relevant similarity considerations for such model tests are discussed and the applicability of model scale tests is demonstrated. Finally, the most important parameters influencing the aerodynamic efficiency of typical ventilator installations in shed-roofs and curved or shed-type light streets are described for the cases without and with side wind.

The Trade-off between Solar Reflectance and Above-Sheathing Ventilation for Metal Roofs on Residential and Commercial Buildings  

SciTech Connect

An alternative to white and cool-color roofs that meets prescriptive requirements for steep-slope (residential and non-residential) and low-slope (non-residential) roofing has been documented. Roofs fitted with an inclined air space above the sheathing (herein termed above-sheathing ventilation, or ASV), performed as well as if not better than high-reflectance, high-emittance roofs fastened directly to the deck. Field measurements demonstrated the benefit of roofs designed with ASV. A computer tool was benchmarked against the field data. Testing and benchmarks were conducted at roofs inclined at 18.34 ; the roof span from soffit to ridge was 18.7 ft (5.7 m). The tool was then exercised to compute the solar reflectance needed by a roof equipped with ASV to exhibit the same annual cooling load as that for a direct-to-deck cool-color roof. A painted metal roof with an air space height of 0.75 in. (0.019 m) and spanning 18.7 ft (5.7 m) up the roof incline of 18.34 needed only a 0.10 solar reflectance to exhibit the same annual cooling load as a direct-to-deck cool-color metal roof (solar reflectance of 0.25). This held for all eight ASHRAE climate zones complying with ASHRAE 90.1 (2007a). A dark heat-absorbing roof fitted with 1.5 in. (0.038 m) air space spanning 18.7 ft (5.7 m) and inclined at 18.34 was shown to have a seasonal cooling load equivalent to that of a conventional direct-to-deck cool-color metal roof. Computations for retrofit application based on ASHRAE 90.1 (1980) showed that ASV air spaces of either 0.75 or 1.5 in. (0.019 and 0.038 m) would permit black roofs to have annual cooling loads equivalent to the direct-to-deck cool roof. Results are encouraging, and a parametric study of roof slope and ASV aspect ratio is needed for developing guidelines applicable to all steep- and low-slope roof applications.

Geologic factors in coal mine roof stability--a progress report. Information circular/1984. [Effects of moisture  

SciTech Connect

This report summarizes 10 selected Bureau of Mines research contract reports produced from 1970 to 1980 which consist largely of geologic studies of coal mine roof support problems. Significant highlights from the contract final reports are discussed and presented in practical terms. The selected reports focus on the Appalachian and Illinois coal mining regions. In the Appalachian coal region, two geologic structures, roof rolls and slickensides, predominate over all structures as features that directly contribute to roof falls. Studies of these and other structures are reviewed, and improved methods of utilizing drill core and core logs to prepare hazard maps are presented. Among the reports described are several on the weakening effects of moisture on shale roof, as determined from both laboratory and underground measurements, and an assessment of air tempering as a humidity-control method. Also summarized are findings concerning the time lapse between roof exposure and permanent support installation as a factor in the effectiveness of roof bolting.

A Prototype Roof Deck Designed to Self-Regulate Deck Temperature and Reduce Heat Transfer  

SciTech Connect

A prototype roof and attic assembly exploits the use of radiation, convection and insulation controls to reduce the heat transfer penetrating its roof deck by almost 85% of the heat transfer crossing a conventional roof and attic assembly. The assembly exhibited attic air temperatures that did not exceed the peak day outdoor ambient temperature. The design includes a passive ventilation scheme that pulls air from the soffit and attic into an inclined air space above the deck. The design complies with fire protection codes because the air intake is internal and closed to the elements. Field data were benchmarked against an attic computer tool and simulations made for new and retrofit home constructions in hot, moderate and cold climates to access economics for the assembly.

Analysis of water heater standby energy consumption from ELCAP homes  

Science Journals Connector (OSTI)

The Bonneville Power Administration (Bonneville) routinely prepares forecasts of future energy demands in the Pacific Northwest region of the United States. Bonneville also implements conservation programs to reduce load demands. Results from the End-Use Load and Consumer Assessment Program (ELCAP), undertaken by the Pacific Northwest Laboratory for Bonneville, indicated that single-family homes with electric space-heating equipment consume more than 4700 kWh/yr to heat water for domestic uses. This energy use amounts to about 23% of the total electricity consumed. Additionally, the peak consumption for water heating coincides with regional system peak demands. Detailed analyses of the water heating end-use data acquired for residential buildings in ELCAP reveal that the average standby load for existing homes is 1200 kWh/yr, while homes built as part of the Residential Standards Demonstration Program averaged 1100 kWh/yr. These figures are consistent with the current figure of 1300 kWh/yr that is being used in the regional energy forecast. We also determined that standby loads for some of the participants were behaviorally driven. The data indicated the occurrence of vacancy setbacks in which the participant appears to lower the thermostat to save energy while the house is vacant. Anecdotal evidence from interviews revealed that this does occur. Reasons for setting back the thermostat ranged from not thinking about using the breaker, to fear that the tank would freeze in cold weather. These types of activities also appear to create the occurrence of dueling thermostats where the upper and lower thermostats, after the vacancy period, are not returned to the same temperature. This leads to additional energy use in an attempt to maintain a uniform temperature in the tank.

Due to the solar arrays, local and regional wind patterns within a 300 km radius were affected. Statistically significant but lower magnitude changes to temperature and radiation could be seen across the domain due to the introduction of the solar arrays.

Frangible roof joint behavior of cylindrical oil storage tanks designed to API 650 rules  

SciTech Connect

This paper presents the results of an investigation into the frangible joint behavior of tanks designed to API 650 rules. In such tanks, the roof-to-shell joint is intended to fail in the event of overpressurization, venting the tank and containing any remaining fluid. The reasoning behind present API design formulas is reviewed. Combustion analyses, structural analyses, and the results of testing are presented. Results show that higher pressures are reached before frangible joint failure than predicted by the present API 650 calculation. One consequence is that (for empty tanks) uplift of the bottom can be expected to occur more frequently than predicted using API 650. However, uplift does not necessarily mean bottom failure. Instead, the relative strength of the shell-to-bottom and roof-to-shell joints will determine failure. This ratio is larger for larger tanks. Recommendations are made as to possible changes in the design approach of API 650.

SciTech Connect

In this thesis, the existing Geomechanics Classification (Bieniawski, 1979) was modified for use in underground coal mines through the introduction of adjustment modifiers for strata weathering, horizontal stress, and roof support. Sixty-two roof case histories were collected from two mines exploiting the Pittsburgh and Lower Kittanning coal seams. Geologic and material property variables were examined with respect to supported stand-up time, while survival and regression analyses were used in deriving the adjustment multipliers. Guidelines for roofspan selection and roof support design were an integral facet of the modified classification scheme. Tentative design guidelines for chain pillars are provided on the basis of a field investigation and numerical modeling of longwall chain pillar behavior. A longwall chain pillar was instrumented with vibrating wire stressmeters to quantify the change in stress distribution as longwall mining proceeded out by the pillar. A sonic probe was used to conduct a velocity profile across the pillar before and after mining to delineate the failed and stable regions of the pillar. Velocity profiles across the pillar were supplemented by an examination of changes in the dynamic modulus and the shear wave frequency. The main contributions of the research lies in: (i) modifications introduced to the Geomechanics Classification (RMR System), (ii) the correlation between changes in pillar stress and the extent of the yield zone surrounding a longwall chain pillar, and (iii) the proposal of design procedures involving coal mine roof support and chain pillars. Numerical examples obtained from mine case histories are provided to illustrate the use of the design procedures.

Roof and Attic Design Guidelines for new and retrofit Construction of Homes in Hot and Coild Climates  

SciTech Connect

Some guidelines for improving the energy efficiency of roofs and attics are presented and are based on the research of the DOE Building Technology. The results of combined analytical and experimental studies were used to benchmark computer tools, which in turn, were used to simulate homes in hot and cold climates. Adding floor and roof insulation, above deck ventilation, radiant barriers, cool color shingle, metal or tile roofs, sealing the attic floor, sealing the duct system and sealing the attic were simulated to compute the cost of energy savings. Results are prioritized to help building owners make an informed economic decision when contemplating roof and attic retrofits. Sealing the attic floor is a top retrofit option. The sealed attic approach and a new prototype roof assembly an insulated and ventilated roof are good options for retrofit work but have paybacks ranging from 15 to 25 years. A new sealed attic concept was simulated and computations show its simple payback is about 10 to 12 years in hot and cold climates; its first cost is significantly reduced from that of a spray foam approach. For new construction the best option is to keep the ducts out of the attic, make sure the attic floor is sealed and add at least code level of insulation to the ceiling.

Carbon sequestration potential of green roofs using mixed-sewage-sludge substrate in Chengdu World Modern Garden City  

Science Journals Connector (OSTI)

Abstract Green roofs which use sewage sludge to sequestrate urban carbon dioxide may represent a potential opportunity to evaluate carbon sequestration benefits for the urban development under increasing global climate change. In this study, green roofs composed of 6 small green segments with two different substrates, mixed-sewage-sludge substrate (MSSS, volume ratio of sewage sludge and local-natural soil 1:1), and local-natural soil (LNS), three different substrate depths (20cm, 25cm and 30cm), and three types of native plants (Ligustrum vicaryi, Neottia auriculata, and Liriope spicata) in Chengdu City were established to determine carbon sequestration from July 2012 to July 2013 through assessment of the carbon storage and sequestration. Results show that the average carbon storage of MSSS and LNS on green roofs was respectively 13.15kgCm?2 and 8.58kgCm?2, and the average carbon sequestration followed the order of LNS (3.89kgCm?2yr?1)>MSSS (3.81kgCm?2yr?1). Thus MSSS could be considered as a potential material for carbon sequestration. The carbon storage and carbon sequestration by native plants on the green roofs followed the order of L. vicaryi>L. spicata>N. auriculata. The whole green roof had a mean carbon storage of 18.28kgCm?2 and average carbon sequestration of 6.47kgCm?2yr?1 in the combined biomass and substrate organic matter. The best green roof configuration was L. vicaryi together with MSSS substrate, with a middle-high level of carbon sequestration. It will be feasible and worthwhile to scale-up the adaptable green roof configurations in Chengdu World Modern Garden City.

Hot Water System Hot Water System The production and delivery of hot water in the CUSD home is technologically advanced, economical, and simple. Hot water is produced primarily by the evacuated solar thermal tube collectors on the roof of the house. The solar thermal tube array was sized to take care of the majority of our heating and hot water needs throughout the course of the year in the Washington, DC climate. The solar thermal tube array also provides heating to the radiant floor. The hot water and radiant floor systems are tied independently to the solar thermal tube array, preventing the radiant floor from robbing the water heater of much needed thermal energy. In case the solar thermal tubes are not able to provide hot water to our system, the hot water tank contains an electric heating

Airtightness Results of Roof-Only Air Sealing Strategies on 1-1/2 Story Homes in Cold Climates  

SciTech Connect

In this second study on solutions to ice dams in 1-1/2 story homes, five test homes located in both cold and very cold climates were analyzed for air leakage reduction rates following modifications by independent contractors on owner-occupied homes. The reason for choosing this house type was they are very common in our area and very difficult to air seal and insulate effectively. Two projects followed a roof-only Exterior Thermal Moisture Management System (ETMMS) process. One project used an interior-only approach to roof air sealing and insulation. The remaining two projects used a deep energy retrofit approach for whole house (foundation wall, above grade wall, roof) air leakage and heat loss reduction. All were asked to provide information regarding project goals, process, and pre and post-blower door test results. Additional air leakage reduction data was provided by several NorthernSTAR Building America industry partners for interior-applied, roof-only modifications on 1-1/2 story homes. The data represents homes in the general market as well as homes that were part of the state of Minnesota weatherization program. A goal was to compare exterior air sealing methods with interior approaches. This pool of data enabled us to compare air tightness data from over 220 homes using similar air seal methods.

Comparative laboratory evaluation of resin-grouted roof bolt elements. Report of Investigations/1985  

SciTech Connect

In laboratory testing, the Bureau of Mines established criteria by which common resin-grouted roof-bolting systems can be evaluated and compared. Ultimate strength and stiffness were determined for nontensioned full-column, point-anchor, tensioned full-column, and debondable resin-grouted bolts, and for variations on full-column bolts. Bolt performances were compared using the performance of the 3/4-in full-column resin-grouted bolt as the standard. New and innovative systems can also be qualitatively compared against this standard. Various host mediums were used in the testing: sandstone, concrete, simulated coal, simulated shale, and plaster. Bolt performances expected in other mediums can be inferred from the response patterns obtained in these mediums.

Rigid foam polyurethane (PU) derived from castor oil (Ricinus communis) for thermal insulation in roof systems  

Science Journals Connector (OSTI)

This paper discusses the response of the thermal insulation lining of rigid foam polyurethane (PU) derived from castor oil (Ricinus communis) in heat conditions, based on dynamic climate approach. Liners have been widely used, because the coverage of buildings is responsible for the greatest absorption of heat by radiation, but the use of PU foam derived from this vegetal oil is unprecedented and has the advantage of being biodegradable and renewable. The hot wire parallel method provided the thermal conductivity value of the foam. The thermogravimetric analysis enabled the study of the foam decomposition and its lifetime by kinetic evaluation that involves the decomposition process. The PU foam thermal behavior analysis was performed by collecting experimental data of internal surface temperature measured by thermocouples and assessed by representative episode of the climatic fact. The results lead to the conclusion that the PU foam derived from castor oil can be applied to thermal insulation of roof systems and is an environmentally friendly material.

Chapter 5 - Solar Water-Heating Systems  

Science Journals Connector (OSTI)

Abstract Chapter 5 is on solar water-heating systems. Both passive and active systems are described. Passive systems include thermosiphon and integrated collector storage systems. The former include theoretical performance of thermosiphon solar water heaters, reverse circulation in thermosiphon systems, vertical against horizontal tank configurations, freeze protection, and tracking thermosiphons. Subsequently, active systems are described, which include direct circulation systems, indirect water-heating systems, air water-heating systems, heat pump systems and pool heating systems, which include the analysis of various heat losses like evaporation, radiation, convection heat losses, make-up water load, and solar radiation-heat gain. Then the characteristics and thermal analysis of heat storage systems for both water and air systems are presented. The module and array design methods are then described and include the effects of shading, thermal expansion, galvanic corrosion, array sizing, heat exchangers, pipe and duct losses, partially shaded collectors and over-temperature protectionfollowed by an analysis of the characteristics of differential thermostats. Finally, methods to calculate the hot water demand are given as well as a review of international standards used to evaluate the solar water heaters performance. The chapter includes also simple system models and practical considerations for the setup of solar water-heating systems, which include: pipes, supports and insulation; pumps; valves and instrumentation.

WIPP supplementary roof support system, Room 1, Panel 1: Geotechnical field data analysis bi-annual report  

SciTech Connect

In June 1991, Waste Isolation Division (WID) initiated the design effort to develop a supplementary roof support system to extend the life of Room 1, Panel 1, to allow successful completion of the bin-scale test program. A number of potential options for ground control were considered leading to the finalization of the currently installed roof support system. This highly instrumented system is ``state of the art`` for mine ground control and will provide extensive geotechnical data. The system is an innovative blend of several standard techniques and incorporates five of the suggestions made by the Geotechnical Panel in its report of June 1991, on the effective life of Rooms in Panel 1. The design was subjected to an exhaustive scrutiny by two formal Design Review Panels and was approved based on reviewed design documents, on-site observations at the WIPP underground facility, and detailed discussions with members of the design team. The original requirement was to have only a section of the room completed in October in preparation for first waste receipt. This goal was met and the relatively complex installation in the entire room was completed in December 1991. The Support System, with all its instrumentation, is now fully operational and generating geotechnical data. Examination of extensometer, closure and load cell data indicate that Room support is performing within the design parameters. All the anchors were initially loaded to approximately 445 kN (1000 lbs). The results of load cell monitoring indicates a steady increase of load on the rock bolts. The anchors installed near the room centerline have shown the greatest increase with the outermost anchors showing little or no load.

Energy Industries of Ohio was the lead organization for a consortium that examined the current situation involving the service life of electric arc and basic oxygen furnace hoods, roofs and side vents. Republic Engineered Products (REP), one of the project partners, installed a full-scale Al-Bronze skirt in their BOF at their Lorain OH facility, believed to be the first such installation of this alloy in this service. In 24 months of operation, the Al-Bronze skirt has processed a total of 4,563 heats, requiring only 2 shutdowns for maintenance, both related to physical damage to the skirt from operational mishaps. Yearly energy savings related to the REP facility are projected to be ~ 10 billion Btu's with significant additional environmental and productivity benefits. In recognition of the excellent results, this project was selected as the winner of the Ohios 2006 Governors Award for Excellence in Energy, the states award for outstanding achievements in energy efficiency.

Thermal and sanitary performance of domestic hot water cylinders: Conflicting requirements  

Science Journals Connector (OSTI)

Abstract In order to understand the sanitary implications around the demand side management of domestic hot water cylinders, microbial samples were taken from the bottom of 10 UK domestic electric hot water tanks whose heating elements are connected to a controlled off-peak supply. The results indicated high concentrations of bacteria in the water and biofilm. Microbial concentrations remained high in spite of the application of seven hours of heating during off-peak hours. Further numerical and experimental work shows that this problem arises due to the differing modes of heat transfer that prevail above and below the immersion element. The results from thermal and bacterial growth models suggest that it is impossible to achieve sanitary conditions throughout standard domestic hot water tanks without significantly increasing the heating element temperature or lowering the heating element from its current position. Raising the immersion thermostat temperature results in additional heat losses whilst lowering the immersion position compromises thermal stratification leading to uneconomical operation. Guidelines around storing hot water at temperatures that are sufficient for the purposes of sterilizing human pathogens such as Legionella, fail to take account of the conflict between thermal and sanitary performance. By better understanding the distribution of temperatures and bacteria within hot water tanks along with the associated risks, improved design and control strategies may be adopted to facilitate effective demand side management of hot water systems whilst meeting sanitary requirements.

A detailed analysis of gains and losses of a fully-integrated flat roof amorphous silicon photovoltaic plant  

Science Journals Connector (OSTI)

In 2003 a fully-integrated photovoltaic (PV) plant composed by amorphous silicon PV modules was installed on top of a flat roof in Lugano (Southern Switzerland) a site representative for most of continental Europe and continuously monitored since. This work follows a previous study which analyzed the first 2years of operation of the plant, ascribing most of the noticeable winter losses to reflection losses due the lower position of the sun in the sky. Other loss mechanisms were discussed only from a qualitative point of view. The energy production of this particular PV installation is in fact influenced by several combined phenomena such as StaeblerWronski, spectral variations, temperature and optical losses effects. The present work aims to widen the analysis by discerning between these partly competitive effects and attempts to give a quantitative description of the influence which each single phenomenon has on the energy performance of the PV plant. For this purpose, single PV modules similar to those of the plant (triple-junction a-Si) were subjected to several indoor and outdoor tests. By means of indoor characterization we found that reflection losses become significant for angles of incidence larger than 50. Repeated indoor and outdoor degradationrecovery cycles underlined the influence of annealing time and temperature on the recovery of the PV modules. In particular outdoor degradation tests showed that at our latitudes (46N) the influence of the StaeblerWronski effect on the output power of these devices is around 10% (5% around an annual average value). The influence of the spectral effects on the current of amorphous silicon modules was assessed by means of outdoor IV characterization: the short circuit current decreases linearly with AM value at a slope between 4% and 8% per AM-unit depending on the technology under investigation. Combining these three effects with the effect of temperature the authors are able to perform a simulation of gains and losses of the a-Si modules which well approximates the energy performance of the CPT-Solar plant over a whole year.

Mathematical analysis of the influence of the chimney height and collector area on the performance of a roof top solar chimney  

Science Journals Connector (OSTI)

Abstract Determination of the roof top solar chimney behaviour during the day time is essential for the proper designing and sizing. This paper presents a mathematical model and analysis of an inclined type roof top solar chimney. The thermal energy and fluid flow processes were simulated mathematically based on the energy and mass balances. The model was converted to a MATLAB computer program and solved by iteration method. The analysis was carried out at various collector areas (15, 150, and 600m2) and various chimney heights (5, 10, and 15m). The model was validated by comparing the results with the experimental measurements. The developed mathematical model was able to predict the dynamic behaviour of the system. The results demonstrated that the performance of the system is highly influenced by the solar intensity. The system becomes functional for space ventilation when the solar intensity is higher than 400W/m2 with a 15m2 collector area and 5m chimney height, under Malaysia and similar weather conditions. As the wind speed increases from 1.5 to 6m/s, it contributes to reduce the system performance by 25% at solar intensity of 900W/m2.

Experimental study of integrated collector storage solar water heaters  

Science Journals Connector (OSTI)

Three Integrated Collector Storage Solar Water Heaters (ICSSWH) have been designed, constructed and experimentally studied in comparison to a Flat Plate Thermosiphonic Unit (FPTU). Each of the ICS experimental models consists of one cylindrical tank horizontally mounted in a stationary symmetrical Compound Parabolic Concentrating (CPC) reflector trough. The main objective is the design and construction of low cost solar water heaters with improved thermal performance and lower possible depths. The experimental models can be mounted on horizontal as well as on inclined roofs by adopting the lowest possible depth. The results show that these solar devices perform more than effectively all year long. This could contribute significantly on the development of ICS type solar water heaters.

Thermal performance analysis of a direct-expansion solar-assisted heat pump water heater  

Science Journals Connector (OSTI)

A direct-expansion solar-assisted heat pump water heater (DX-SAHPWH) is described, which can supply hot water for domestic use during the whole year. The system mainly employs a bare flat-plate collector/evaporator with a surface area of 4.2m2, an electrical rotary-type hermetic compressor, a hot water tank with the volume of 150L and a thermostatic expansion valve. R-22 is used as working fluid in the system. A simulation model based on lumped and distributed parameter approach is developed to predict the thermal performance of the system. Given the structure parameters, meteorological parameters, time step and final water temperature, the numerical model can output operational parameters, such as heat capacity, system COP and collector efficiency. Comparisons between the simulation results and the experimental measurements show that the model is able to give satisfactory predictions. The effect of various parameters, including solar radiation, ambient temperature, wind speed and compressor speed, has been analyzed on the thermal performance of the system.

Experimental study of the density and derived (excess, apparent, and partial molar volumes) properties of binary water+ethanol and ternary water+ethanol+lithium nitrate mixtures at temperatures from 298K to 448K and pressures up to 40MPa  

Science Journals Connector (OSTI)

Abstract Densities of binary water+ethanol and ternary water+ethanol+LiNO3 mixtures have been measured over the temperature range from 298K to 448K and at pressures up to 40MPa using the constant-volume piezometer immersed in a precision liquid thermostat. The measurements for water+ethanol mixture were made for four compositions of 0.0163, 0.0343, 0.0730, and 0.0946mol fraction of ethanol. The measurements for thernary water+ethanol+LiNO3 mixtures were performed in the same temperature and pressure ranges for twelve concentrations. The combined expanded uncertainty of the density, pressure, temperature, and concentration measurements at the 95% confidence level with a coverage factor of k=2 is estimated to be 0.06%, 0.05%, 20mK, and 0.015%, respectively. The derived volumetric properties such as excess ( V m E ), apparent ( V ? ), and partial ( V 2 ? ) molar volumes were calculated using the measured values of density for the binary water+ethanol mixture and for pure water and ethanol. The small and negative values of excess molar volume for the mixtures were found at all experimental temperatures, pressures, and over the entire concentration range. The excess molar volume minimum is found at concentration about 0.4mol fraction of 1-propanol. The concentration minimum of the derived apparent molar volumes V ? near 2molkg?1 (dilute mixture) was observed.

Temporary Waters  

Science Journals Connector (OSTI)

Temporary waters are lakes, ponds, streams, seeps, microhabitats, and other areas that hold water periodically and then dry. They occur across the globe, at all latitudes, and in all biomes, wherever water can collect long enough for aquatic life to develop. These waters are numerous, mostly small, and easily studied. Their biological communities are diverse, have much among-site variation, often include endemic species, and differ from those in permanent waters, contributing to regional biodiversity. Organisms survive through species-specific behavioral, physiological, and life-history adaptations. Community composition and structure change in response to environmental variations. Temporary waters are highly productive and their food webs are relatively simple. For all of these reasons, temporary waters lend themselves to surveys and experimental manipulations designed to test hypotheses about biological adaptation, population regulation, evolutionary processes, community composition and structure, and ecosystem functioning. In many parts of the world, most temporary waters have been lost. The conservation and restoration of vulnerable temporary waters is a major thrust of applied ecology. Also important are applications of ecological understanding to the control of disease vectors, especially pathogen-transmitting mosquitoes, from temporary water habitats.

Bugs Bugs Nature Bulletin No. 221-A March 12, 1966 Forest Preserve District of Cook County Seymour Simon, President Roland F. Eisenbeis, Supt. of Conservation WATER BUGS It is fascinating to lie in a boat or on a log at the edge of the water and watch the drama that unfolds among the small water animals. Among the star performers in small streams and ponds are the Water Bugs. These are aquatic members of that large group of insects called the "true bugs", most of which live on land. Moreover, unlike many other types of water insects, they do not have gills but get their oxygen directly from the air. Those that do go beneath the surface usually carry an oxygen supply with them in the form of a shiny glistening sheath of air imprisoned among a covering of fine waterproof hairs. The common water insect known to small boys at the "Whirligig Bug" is not a water bug but a beetle.

Experimental analysis of a direct expansion solar assisted heat pump with integral storage tank for domestic water heating under zero solar radiation conditions  

Science Journals Connector (OSTI)

This paper deals with the experimental evaluation of the performance of a direct expansion solar assisted heat pump water heating (DX-SAHPWH) system working under zero solar radiation conditions at static heating operation mode of the storage tank. The DX-SAHPWH system includes two bare solar collectors as evaporator, a \\{R134a\\} rotary-type hermetic compressor, a thermostatic expansion valve and a helical coil condenser immersed in a 300L water storage tank. The zero solar radiation and stable ambient air temperature working conditions were established by placing the solar collectors into a climate chamber. The analysis is based on experimental data taken from the DX-SAHPWH provided by the manufacturer and equipped with an appropriate data acquisition system. In the paper, the experimental facility, the data acquisition system and the experimental methodology are described. Performance parameters to evaluate the energy efficiency, such as COP and equivalent seasonal performance factors (SPFe) for the heating period, and the water thermal stratification in the storage tank are defined and obtained from the experimental data. Results from the experimental analysis under transient operating working conditions of the DX-SAHPWH system and its main components are shown and discussed. Lastly, the Huang and Lee DX-SAHPWH performance evaluation method was applied resulting in a characteristic COP of 3.23 for the DX-SAHPWH system evaluated under zero solar radiation condition.

Eisenbeis Supt. of Conservation WATER BEETLES The world is full of beetles. They live everywhere except in the oceans and in the polar regions. There are more of them than any other kind of insect. A quarter of a million species are known and new ones are being discovered every year. Whether it is a microscopic mushroom beetle a hundredth of an inch long, or a giant six-inch Hercules beetle from South America, it can be recognized by its wings. The upper pair forms a hard shell curving like a shield over the thin folded lower wings and the abdomen. In flight, the upper pair is extended like the wings of an airplane and the lower two become buzzing propellers.

Water covers more than two thirds of the surface of the Earth and about the same fraction of water forms the total mass of a human body. Since the early days of our civilization water has also been in the focus of technological developments, starting from converting it to wine to more modern achievements. The meeting will focus on recent advances in experimental, theoretical, and computational understanding of the behavior of the most important and fascinating liquid in a variety of situations and applications. The emphasis will be less on water properties per se than on water as a medium in which fundamental dynamic and reactive processes take place. In the following sessions, speakers will discuss the latest breakthroughs in unraveling these processes at the molecular level: Water in Solutions; Water in Motion I and II; Water in Biology I and II; Water in the Environment I and II; Water in Confined Geometries and Water in Discussion (keynote lecture and poster winners presentations).

Radioactive contamination of cistern waters along the Croatian coast of the Adriatic Sea by [sup 90]Sr  

SciTech Connect

Measurements of radioactive contamination of water samples from cisterns collecting rainwater containing fission products from roofs and other surfaces have been carried out along the Croatian coast of the Adriatic sea since 1968. An exponential decline of radioactivity followed the nuclear moratorium. After the nuclear accident at Chernobyl, higher levels of [sup 137]Cs and [sup 90]Sr were detected again, with cistern waters being the only environmental samples in Croatia in which elevated [sup 90]Sr activities persisted for several years. For the pre-Chernobyl period, the observed mean residence time of [sup 90]Sr in cistern waters, estimated to be 6.2 [+-] 1.9 y, was similar to that calculated for fallout. Contrary, for the post-Chernobyl time, observed [sup 90]Sr mean residence time was calculated to be considerably shorter, reflecting the tropospheric mean residence time. The annual dose for the critical adult population received from [sup 90]Sr and [sup 137]Cs by drinking cistern water was estimated to be very small, in the 1990's less than few [micro]Sv y[sup [minus]1].

Geothermal Water Use: Life Cycle Water Consumption, Water Resource Assessment, and Water Policy Framework  

SciTech Connect

This report examines life cycle water consumption for various geothermal technologies to better understand factors that affect water consumption across the life cycle (e.g., power plant cooling, belowground fluid losses) and to assess the potential water challenges that future geothermal power generation projects may face. Previous reports in this series quantified the life cycle freshwater requirements of geothermal power-generating systems, explored operational and environmental concerns related to the geochemical composition of geothermal fluids, and assessed future water demand by geothermal power plants according to growth projections for the industry. This report seeks to extend those analyses by including EGS flash, both as part of the life cycle analysis and water resource assessment. A regional water resource assessment based upon the life cycle results is also presented. Finally, the legal framework of water with respect to geothermal resources in the states with active geothermal development is also analyzed.

Development of a Water Based, Critical Flow, Non-Vapor Compression cooling Cycle  

SciTech Connect

Expansion of a high-pressure liquid refrigerant through the use of a thermostatic expansion valve or other device is commonplace in vapor-compression cycles to regulate the quality and flow rate of the refrigerant entering the evaporator. In vapor-compression systems, as the condensed refrigerant undergoes this expansion, its pressure and temperature drop, and part of the liquid evaporates. We (researchers at Kansas State University) are developing a cooling cycle that instead pumps a high-pressure refrigerant through a supersonic converging-diverging nozzle. As the liquid refrigerant passes through the nozzle, its velocity reaches supersonic (or critical-flow) conditions, substantially decreasing the refrigerants pressure. This sharp pressure change vaporizes some of the refrigerant and absorbs heat from the surrounding conditions during this phase change. Due to the design of the nozzle, a shockwave trips the supersonic two-phase refrigerant back to the starting conditions, condensing the remaining vapor. The critical-flow refrigeration cycle would provide space cooling, similar to a chiller, by running a secondary fluid such as water or glycol over one or more nozzles. Rather than utilizing a compressor to raise the pressure of the refrigerant, as in a vapor-cycle system, the critical-flow cycle utilizes a high-pressure pump to drive refrigerant liquid through the cooling cycle. Additionally, the design of the nozzle can be tailored for a given refrigerant, such that environmentally benign substances can act as the working fluid. This refrigeration cycle is still in early-stage development with prototype development several years away. The complex multi-phase flow at supersonic conditions presents numerous challenges to fully understanding and modeling the cycle. With the support of DOE and venture-capital investors, initial research was conducted at PAX Streamline, and later, at Caitin. We (researchers at Kansas State University) have continued development of the cycle and have gained an in-depth understanding of the governing fundamental knowledge, based on the laws of physics and thermodynamics and verified with our testing results. Through this research, we are identifying optimal working fluid and operating conditions to eventually demonstrate the core technology for space cooling or other applications.

Water and terrorism  

E-Print Network (OSTI)

The importance of freshwater and water infrastructure to human and ecosystem health and to the smooth functioning of a commercial and industrial economy makes water and water systems targets for terrorism. The chance that terrorists will strike at water systems is real; indeed, there is a long history of such attacks. Water infrastructure can be targeted directly or water can be contaminated through the introduction of poison or diseasecausing agents. The damage is done by hurting people, rendering water unusable, or destroying purification and supply infrastructure. More uncertain, however, is how significant such threats are today, compared with other targets that may be subject to terrorist attack, or how effective such attacks would actually be. Analysis and historical evidence suggest that massive casualties from attacking water systems are difficult to produce, although there may be some significant exceptions. At the same time, the risk of societal disruptions, disarray, and even overreaction on the part of governments and the public from any attack, may be high. This paper reviews the history of past attacks on water systems and the most pressing vulnerabilities and risks facing modern water systems. Suggestions of ways to reduce those risks are also presented.

Purge water management system  

DOE Patents (OSTI)

A purge water management system is described for effectively eliminating the production of purge water when obtaining a groundwater sample from a monitoring well. In its preferred embodiment, the purge water management system comprises an expandable container, a transportation system, and a return system. The purge water management system is connected to a wellhead sampling configuration, typically permanently installed at the well site. A pump, positioned with the monitoring well, pumps groundwater through the transportation system into the expandable container, which expands in direct proportion with volume of groundwater introduced, usually three or four well volumes, yet prevents the groundwater from coming into contact with the oxygen in the air. After this quantity of groundwater has been removed from the well, a sample is taken from a sampling port, after which the groundwater in the expandable container can be returned to the monitoring well through the return system. The purge water management system prevents the purge water from coming in contact with the outside environment, especially oxygen, which might cause the constituents of the groundwater to oxidize. Therefore, by introducing the purge water back into the monitoring well, the necessity of dealing with the purge water as a hazardous waste under the Resource Conservation and Recovery Act is eliminated.

Water, and its uses or control, has become a vital national problem. Some places, some years, we have too much of it and suffer disastrous floods. Elsewhere we have too little. In cities like New York and Los Angeles -- even in many inland towns -- and in the western lands which depend upon irrigation, the demand far exceeds the supply. Our Congress is beseeched for huge appropriations to provide flood control, navigation, electric power and irrigation.

Photobiological Water Splitting  

Energy.gov (U.S. Department of Energy (DOE))

In this process, hydrogen is produced from water using sunlight and specialized microorganisms, such as green algae and cyanobacteria. Just as plants produce oxygen during photosynthesis, these microorganisms consume water and produce hydrogen as a byproduct of their natural metabolic processes. Photobiological water splitting is a long-term technology. Currently, the microbes split water much too slowly to be used for efficient, commercial hydrogen production. But scientists are researching ways to modify the microorganisms and to identify other naturally occurring microbes that can produce hydrogen at higher rates. Photobiological water splitting is in the very early stages of research but offers long-term potential for sustainable hydrogen production with low environmental impact.

Water's Hydrogen Bond Strength  

E-Print Network (OSTI)

Water is necessary both for the evolution of life and its continuance. It possesses particular properties that cannot be found in other materials and that are required for life-giving processes. These properties are brought about by the hydrogen bonded environment particularly evident in liquid water. Each liquid water molecule is involved in about four hydrogen bonds with strengths considerably less than covalent bonds but considerably greater than the natural thermal energy. These hydrogen bonds are roughly tetrahedrally arranged such that when strongly formed the local clustering expands, decreasing the density. Such low density structuring naturally occurs at low and supercooled temperatures and gives rise to many physical and chemical properties that evidence the particular uniqueness of liquid water. If aqueous hydrogen bonds were actually somewhat stronger then water would behave similar to a glass, whereas if they were weaker then water would be a gas and only exist as a liquid at sub-zero temperatures. The overall conclusion of this investigation is that water's hydrogen bond strength is poised centrally within a narrow window of its suitability for life.

SciTech Connect

A heat transfer liquid collects heat in a solar collector and transfers the heat to water in a preheater heat exchanger. Use of a negative-pressure collector by means of an ejector and pressure relief valve allows inexpensive and readily available materials to be used in the collector. Preferably, the preheat heat exchanger is a converted gas hot water heater in which the heat transfer liquid is sprayed onto a portion of the storage tank and is collected in a reservoir. The negative-pressure solar collector can also be used to heat swimming pool water.

Treatment of brackish water  

SciTech Connect

Brackish water resulting from steam extraction of heavy crude oils, including oil sands bitumen, is processed for reuse by removing hydrocarbon contamination and removing mineral contamination. The purified water can be boiled in conventional boilers without scaling or fouling occurring. Heat economy is used in conducting the process. The brackish water is first subjected to oil removal by separating out as much of the free oil as possible, such as by using gravity separation and air flotation, and then stripping any residual oil by ozone treatment. The hydrocarbon-free water then is subjected to demineralization. The demineralization is effected by a first electrodialysis reversal step to remove minerals other than silica and a second silica removal step. 8 claims.
