Indoor Sampler Siting Indoor Sampler Siting Title Indoor Sampler Siting Publication Type Conference Proceedings Year of Publication 2009 Authors Sohn, Michael D., and David M. Lorenzetti Conference Name 11th International Conference on Air Distribution in Rooms Conference Location Busan, Korea Abstract Contaminant releases in or near a building can lead to significant human exposures unless prompt response is taken. U.S. Federal and local agencies are implementing programs to place air-monitoring samplers in buildings to quickly detect biological agents. We describe a probabilistic algorithm for siting samplers in order to detect accidental or intentional releases of biological material. The algorithm maximizes the probability of detecting a release from among a suite of realistic scenarios. The scenarios may differ in any unknown, for example the release size or location, weather, mode of building operation, etc. The algorithm also can optimize sampler placement in the face of modeling uncertainties, for example the airflow leakage characteristics of the building, and the detection capabilities of the samplers. In anillustrative example, we apply the algorithm to a hypothetical 24-room commercial building, finding optimal networks for a variety of assumed sampler types and performance characteristics. We also discuss extensions of this work for detecting ambient pollutants in buildings, and for understanding building-wide airflow, pollutant dispersion, and exposures

Indoor air radon  

SciTech Connect

This review concerns primarily the health effects that result from indoor air exposure to radon gas and its progeny. Radon enters homes mainly from the soil through cracks in the foundation and other holes to the geologic deposits beneath these structures. Once inside the home the gas decays (half-life 3.8 d) and the ionized atoms adsorb to dust particles and are inhaled. These particles lodge in the lung and can cause lung cancer. The introduction to this review gives some background properties of radon and its progeny that are important to understanding this public health problem as well as a discussion of the units used to describe its concentrations. The data describing the health effects of inhaled radon and its progeny come both from epidemiological and animal studies. The estimates of risk from these two data bases are consistent within a factor of two. The epidemiological studies are primarily for hard rock miners, although some data exist for environmental exposures. The most complete studies are those of the US, Canadian, and Czechoslovakian uranium miners. Although all studies have some deficiencies, those of major importance include uranium miners in Saskatchewan, Canada, Swedish iron miners, and Newfoundland fluorspar miners. These six studies provide varying degrees of detail in the form of dose-response curves. Other epidemiological studies that do not provide quantitative dose-response information, but are useful in describing the health effects, include coal, iron ore and tin miners in the UK, iron ore miners in the Grangesburg and Kiruna, Sweden, metal miners in the US, Navajo uranium miners in the US, Norwegian niobian and magnitite miners, South African gold and uranium miners, French uranium miners, zinc-lead miners in Sweden and a variety of small studies of environmental exposure. An analysis of the epidemiological studies reveals a variety of interpretation problem areas.172 references.

Manual on indoor air quality  

Science Conference Proceedings (OSTI)

This reference manual was prepared to assist electric utilities in helping homeowners, builders, and new home buyers to understand a broad range of issues related to indoor air quality. The manual is directed to technically knowledgeable persons employed by utility companies - the customer service or marketing representative, applications engineer, or technician - who may not have specific expertise in indoor air quality issues. In addition to providing monitoring and control techniques, the manual summarizes the link between pollutant concentrations, air exchange, and energy conservation and describes the characteristics and health effects of selected pollutants. Where technical information is too lengthy or complex for inclusion in this volume, reference sources are given. Information for this manual was gathered from technical studies, manufacturers' information, and other materials from professional societies, institutes, and associations. The aim has been to provide objective technical and descriptive information that can be used by utility personnel to make informed decisions about indoor air quality issues.

Reducing indoor residential exposures to outdoor pollutants  

SciTech Connect

The basic strategy for providing indoor air quality in residences is to dilute indoor sources with outdoor air. This strategy assumes that the outdoor air does not have pollutants at harmful levels or that the outdoor air is, at least, less polluted than the indoor air. When this is not the case, different strategies need to be employed to ensure adequate air quality in the indoor environment. These strategies include ventilation systems, filtration and other measures. These strategies can be used for several types of outdoor pollution, including smog, particulates and toxic air pollutants. This report reviews the impacts that typical outdoor air pollutants can have on the indoor environment and provides design and operational guidance for mitigating them. Poor quality air cannot be used for diluting indoor contaminants, but more generally it can become an indoor contaminant itself. This paper discusses strategies that use the building as protection against potentially hazardous outdoor pollutants, including widespread pollutants, accidental events, and potential attacks.

Characterizing the source of radon indoors  

Science Conference Proceedings (OSTI)

Average indoor radon concentrations range over more than two orders of magnitude, largely because of variability in the rate at which radon enters from building materials, soil, and water supplies. Determining the indoor source magnitude requires knowledge of the generation of radon in source materials, its movement within materials by diffusion and convection, and the means of its entry into buildings. This paper reviews the state of understanding of indoor radon sources and transport. Our understanding of generation rates in and movement through building materials is relatively complete and indicates that, except for materials with unusually high radionuclide contents, these sources can account for observed indoor radon concentrations only at the low end of the range observed. Our understanding of how radon enters buildings from surrounding soil is poorer, however recent experimental and theoretical studies suggest that soil may be the predominant source in many cases where the indoor radon concentration is high. 73 references, 3 figures, 1 table.

Indoor environment program. 1994 annual report  

Science Conference Proceedings (OSTI)

Buildings use approximately one-third of the energy consumed in the United States. The potential energy savings derived from reduced infiltration and ventilation in buildings are substantial, since energy use associated with conditioning and distributing ventilation air is about 5.5 EJ per year. However, since ventilation is the dominant mechanism for removing pollutants from indoor sources, reduction of ventilation can have adverse effects on indoor air quality, and on the health, comfort, and productivity of building occupants. The Indoor Environment Program in LBL`s Energy and Environment Division was established in 1977 to conduct integrated research on ventilation, indoor air quality, and energy use and efficiency in buildings for the purpose of reducing energy liabilities associated with airflows into, within, and out of buildings while maintaining or improving occupant health and comfort. The Program is part of LBL`s Center for Building Science. Research is conducted on building energy use and efficiency, ventilation and infiltration, and thermal distribution systems; on the nature, sources, transport, transformation, and deposition of indoor air pollutants; and on exposure and health risks associated with indoor air pollutants. Pollutants of particular interest include radon; volatile, semivolatile, and particulate organic compounds; and combustion emissions, including environmental tobacco smoke, CO, and NO{sub x}.

Research review: Indoor air quality control techniques  

Science Conference Proceedings (OSTI)

Techniques for controlling the concentration of radon, formaldehyde, and combustion products in the indoor air are reviewed. The most effective techniques, which are generally based on limiting or reducing indoor pollutant source strengths, can decrease indoor pollutant concentrations by a factor of 3 to 10. Unless the initial ventilation rate is unusually low, it is difficult to reduce indoor pollutant concentrations more than approximately 50% by increasing the ventilation rate of an entire building. However, the efficiency of indoor pollutant control by ventilation can be enhanced through the use of local exhaust ventilation near concentrated sources of pollutants, by minimizing short circuiting of air from supply to exhaust when pollutant sources are dispersed and, in some situations, by promoting a displacement flow of air and pollutants toward the exhaust. Active air cleaning is also examined briefly. Filtration and electrostatic air cleaning for removal of particles from the indoor air are the most practical and effective currently available techniques of air cleaning. 49 refs., 7 figs.

3 3 A Survey: Indoor Air Quality in Schools We recently undertook a survey and critical review of the published literature on indoor air quality (IAQ), ventilation, and IAQ- and building-related health problems in schools, particularly those in the state of California. The survey's objectives included identifying the most commonly reported building-related health symptoms involving schools, and assembling and evaluating existing measurement data on key indoor air pollutants most likely to be related to these symptoms. The review also summarizes existing measurements of ventilation rates in schools and information on the causes of IAQ and health problems in schools. Most of the literature we reviewed (more than 450 articles and reports) dealt with complaint or problem schools. Among the papers were

Indoor air pollution: a new concern  

SciTech Connect

Radon, asbestos, and formaldehyde are emerging as major health hazards because home-winterization efforts are trapping toxic agents indoors. Other pollution sources, such as tobacco smoke and unvented heating units, also lower indoor air quality. Radon decay products present in the structural materials of well-insulated homes are linked to lung-cancer deaths. Exposure to asbestos fibers has been identified as a problem in many school buildings, while physical discomfort caused by urea-formaldehyde foam insulation has affected the health of many homeowners. The Environmental Protection Agency is collecting and disseminating information to help local officials and homeowners understand the risks and is urging building auditors to inform clients about indoor air pollution.

Gas ranges: latest indoor pollution target  

Science Conference Proceedings (OSTI)

Although a National Research Council study claims that unvented gas cooking and heating appliance are probably responsible for a large portions of the nitrogen dioxide exposures in the population, the data base for gas-stove emissions is actually too limited to be conclusive. The problem of indoor pollution more likely rests with the increased airtightness of houses rather than with gas combustion. In the last 5 years, the normal air flow in new houses has been reduced 80% through new insulation and building techniques designed to lower heating and cooling costs. Other elements contributing to indoor pollution are much more hazardous than gas combustion products: radon gas from the soil, formaldehyde for insulation and construction materials, and toxic chemicals from household aerosols and solvents.

Equivalence in Ventilation and Indoor Air Quality  

SciTech Connect

We ventilate buildings to provide acceptable indoor air quality (IAQ). Ventilation standards (such as American Society of Heating, Refrigerating, and Air-Conditioning Enginners [ASHRAE] Standard 62) specify minimum ventilation rates without taking into account the impact of those rates on IAQ. Innovative ventilation management is often a desirable element of reducing energy consumption or improving IAQ or comfort. Variable ventilation is one innovative strategy. To use variable ventilation in a way that meets standards, it is necessary to have a method for determining equivalence in terms of either ventilation or indoor air quality. This study develops methods to calculate either equivalent ventilation or equivalent IAQ. We demonstrate that equivalent ventilation can be used as the basis for dynamic ventilation control, reducing peak load and infiltration of outdoor contaminants. We also show that equivalent IAQ could allow some contaminants to exceed current standards if other contaminants are more stringently controlled.

Ubiquitous Indoor Localization and Worldwide Automatic Construction of Floor Plans  

E-Print Network (OSTI)

Although GPS has been considered a ubiquitous outdoor localization technology, we are still far from a similar technology for indoor environments. While a number of technologies have been proposed for indoor localization, they are isolated efforts that are way from a true ubiquitous localization system. A ubiquitous indoor positioning system is envisioned to be deployed on a large scale worldwide, with minimum overhead, to work with heterogeneous devices, and to allow users to roam seamlessly from indoor to outdoor environments. Such a system will enable a wide set of applications including worldwide seamless direction finding between indoor locations, enhancing first responders' safety by providing anywhere localization and floor plans, and providing a richer environment for location-aware social networking applications. We describe an architecture for the ubiquitous indoor positioning system (IPS) and the challenges that have to be addressed to materialize it. We then focus on the feasibility of automating ...

An overview of the accelerated, indoor light-soaking test station is presented in this paper, along with data obtained for six modules that underwent exposure. The station comprises a climate-controlled chamber equipped with a solar simulator that allows 1-sun light intensity exposure. Concurrently, we monitor the electrical characteristics of multiple PV modules and exercise active control over their electrical bias using programmable electronic loads, interfaced to a data acquisition system that acquires power-tracking and current-voltage data. This capability allows us to the test different bias conditions and to cyclically alternate between them. Additionally, we can vary the light intensity and module temperatures to garner realistic temperature coefficients of module performance. Data obtained on cadmium telluride (CdTe) and amorphous silicon (a-Si) modules are presented.

Automobile proximity and indoor residential concentrations of BTEX and MTBE  

Science Conference Proceedings (OSTI)

Attached garages have been identified as important sources of indoor residential air pollution. However, the literature lacks information on how the proximity of cars to the living area affects indoor concentrations of gasoline-related compounds, and the origin of these pollutants. We analyzed data from the Relationships of Indoor, Outdoor, and Personal Air (RIOPA) study and evaluated 114 residences with cars in an attached garage, detached garage or carport, or without cars. Results indicate that homes with cars in attached garages were affected the most. Concentrations in homes with cars in detached garages and residences without cars were similar. The contribution from gasoline-related sources to indoor benzene and MTBE concentrations appeared to be dominated by car exhaust, or a combination of tailpipe and gasoline vapor emissions. Residing in a home with an attached garage could lead to benzene exposures ten times higher than exposures from commuting in heavy traffic.

Indoor measurements of environmental tobacco smoke

Indoor measurements of environmental tobacco smoke Indoor measurements of environmental tobacco smoke Title Indoor measurements of environmental tobacco smoke Publication Type Report Year of Publication 2004 Authors Apte, Michael G., Lara A. Gundel, S. Katharine Hammond, Raymond L. Dod, Marion L. Russell, Brett C. Singer, Michael D. Sohn, Douglas P. Sullivan, Gee-Minn Chang, and Richard G. Sextro Publisher Lawrence Berkeley National Laboratory Abstract The objective of this research project was to improve the basis for estimating environmental tobacco smoke (ETS) exposures in a variety of indoor environments. The research utilized experiments conducted in both laboratory and 'real-world' buildings to 1) study the transport of ETS species from room to room, 2) examine the viability of using various chemical markers as tracers for ETS, and 3) to evaluate to what extent re-emission of ETS components from indoor surfaces might add to the ETS exposure estimates. A three-room environmental chamber was used to examine multi-zone transport and behavior of ETS and its tracers. One room (simulating a smoker's living room) was extensively conditioned with ETS, while a corridor and a second room (simulating a child's bedroom) remained smoking-free. A series of 5 sets of replicate experiments were conducted under different door opening and flow configurations: sealed, leaky, slightly ajar, wide open, and under forced air-flow conditions. When the doors between the rooms were slightly ajar the particles dispersed into the other rooms, eventually reaching the same concentration. The particle size distribution took the same form in each room, although the total numbers of particles in each room depended on the door configurations. The particle number size distribution moved towards somewhat larger particles as the ETS aged. We also successfully modeled the inter-room transport of ETS particles from first principles - using size fractionated particle emission factors, predicted deposition rates, and thermal temperature gradient driven inter-room flows, This validation improved our understanding of bulk inter-room ETS particle transport. Four chemical tracers were examined: ultraviolet-absorbing particulate matter (UVPM), fluorescent particulate matter (FPM), nicotine and solanesol. Both (UVPM) and (FPM) traced the transport of ETS particles into the non-smoking areas. Nicotine, on the other hand, quickly adsorbed on unconditioned surfaces so that nicotine concentrations in these rooms remained very low, even during smoking episodes. These findings suggest that using nicotine as a tracer of ETS particle concentrations may yield misleading concentration and/or exposure estimates. The results of the solanesol analyses were compromised, apparently by exposure to light during collection (lights in the chambers were always on during the experiments). This may mean that the use of solanesol as a tracer is impractical in 'real-world' conditions. In the final phase of the project we conducted measurements of ETS particles and tracers in three residences occupied by smokers who had joined a smoking cessation program. As a pilot study, its objective was to improve our understanding of how ETS aerosols are transported in a small number of homes (and thus, whether limiting smoking to certain areas has an effect on ETS exposures in other parts of the building). As with the chamber studies, we examined whether measurements of various chemical tracers, such as nicotine, solanesol, FPM and UVPM, could be used to accurately predict ETS concentrations and potential exposures in 'real-world' settings, as has been suggested by several authors. The ultimate goal of these efforts, and a future larger multiple house study, is to improve the basis for estimating ETS exposures to the general public. Because we only studied three houses no firm conclusions can be developed from our data. However, the results for the ETS tracers are essentially the same as those for the chamber experiments. The use of nicotine was problematic as a marker for ETS exposure. In the smoking areas of the homes, nicotine appeared to be a suitable indicator; however in the non-smoking regions, nicotine behavior was very inconsistent. The other tracers, UVPM and FPM, provided a better basis for estimating ETS exposures in the 'real world'. The use of solanesol was compromised - as it had been in the chamber experiments.

Condition Controlling and Monitoring of Indoor Swimming Pools  

E-Print Network (OSTI)

VTT has executed a lot of research work concerning the usage, functionality and refurbishment of indoor swimming pools and spas lately. This work includes for instance detailed condition surveys, energy audits, cost analysis and maintenance planning tools. The prevailing conditions make special demands for planning, constructing, repairing and maintaining the indoor swimming pools. Main topics are usually connected with shortening of the service lives of the building parts and technical installations and the indoor air quality. Also the yearly running costs can be remarkable high. VTT has created the technical risk map for indoor swimming pool repairs. This risk map presents the most significant factors that must be taken into account in order to repair facilities successfully. Due to optimizing the operation and maintenance VTT has developed operation and maintenance manual software that is specially targeted for indoor swimming facilities. This paper presents the technical risk map, the condition survey procedure, the energy saving methods and the maintenance record book for indoor swimming facilities to secure the success of a refurbishment project.

TEAMS: Indoor Air Quality (IAR) Program  

E-Print Network (OSTI)

The Carrollton-Farmers Branch Independent School District (“CFBISD”) found the need to reduce air quality concerns and complaints, and find an effective and efficient method to reduce the rising cost of utilities. An Indoor Air Quality (IAQ) program was required to embrace the two needs with the overall objective to educate all—teachers, administrators, various departments, and students. The educational outreach program chosen is TEAMS, which is the IAQ program designed to attain these goals. The CFBISD prides itself in acting quickly to resolve IAQ issues. Our belief is problems defined and recognized, create trust, and enable the District to maximize potential for performance improvements via reduced concerns by staff. We’ve had our IAQ program in place since April of 2002. Recognizing the need to expand the program in depth and breadth, we designed TEAMS. We were able to do this by assistance from Mike Miller and the EPA, who gave the District six “Tools for Schools” test kits (TfS Kit). The information from these kits gave us a guideline to build TEAMS to meet our objectives of reaching a larger audience with additional material, and adding to the goals of TEAMS increased efficiency, reduced cost, and educated consumers.

Indoor Thermal Comfort, an Evolutionary Biology Perspective  

Science Conference Proceedings (OSTI)

As is becoming increasingly clear, the human species evolvedin the East African savannah. Details of the precise evolutionary chainremain unresolved however it appears that the process lasted severalmillion years, culminating with the emergence of modern Homo sapiensroughly 200,000 years ago. Following that final evolutionary developmentmodern Homo sapiens relatively quickly populated the entire world.Clearly modern Homo sapiens is a successful, resourceful and adaptablespecies. In the developed societies, modern humans live an existence farremoved from our evolutionary ancestors. As we have learned over the lastcentury, this "new" lifestyle can often result in unintendedconsequences. Clearly, our modern access to food, shelter, transportationand healthcare has resulted in greatly expanded expected lifespan butthis new lifestyle can also result in the emergence of different kinds ofdiseases and health problems. The environment in modern buildings haslittle resemblance to the environment of the savannah. We strive tocreate environments with little temperature, air movement and lightvariation. Building occupants often express great dissatisfaction withthese modern created environments and a significant fraction even developsomething akin to allergies to specific buildings (sick buildingsyndrome). Are the indoor environments we are creating fundamentallyunhealthy -- when examined from an evolutionary perspective?

Indoor environmental quality benefits of apartment energy retrofits Indoor environmental quality benefits of apartment energy retrofits Title Indoor environmental quality benefits of apartment energy retrofits Publication Type Journal Article LBNL Report Number LBNL-6373E Year of Publication 2013 Authors Noris, Federico, Gary Adamkiewicz, William W. Delp, Toshifumi Hotchi, Marion L. Russell, Brett C. Singer, Michael Spears, Kimberly Vermeer, and William J. Fisk Journal Building Environment Volume 68 Pagination 170-178 Date Published 10/2013 Keywords Apartments; Energy; Indoor environmental quality; Retrofit; Selection Abstract Sixteen apartments serving low-income populations in three buildings were retrofit with the goal of simultaneously reducing energy consumption and improving indoor environmental quality (IEQ). Retrofit measures varied among apartments and included, among others, envelope sealing, installation of continuous mechanical ventilation systems, upgrading bathroom fans and range hoods, attic insulation, replacement of heating and cooling systems, and adding wall-mounted particle air cleaners. IEQ parameters were measured, generally for two one-week periods before and after the retrofits. The measurements indicate an overall improvement in IEQ conditions after the retrofits. Comfort conditions, bathroom humidity, and concentrations of carbon dioxide, acetaldehyde, volatile organic compounds, and particles generally improved. Formaldehyde and nitrogen dioxide levels decreased in the building with the highest concentrations, were unchanged in a second building, and increased in a third building. IEQ parameters other than particles improved more in apartments with continuous mechanical ventilation systems installed. In general, but not consistently, larger percent increases in air exchange rates were associated with larger percent decreases in indoor levels of the pollutants that primarily come from indoor sources.

IAQ in Hospitals - Better Health through Indoor Air Quality Awareness  

E-Print Network (OSTI)

Quality air is fundamental to people's health and well-being. Indoor air quality is an important issue from both a social and economic point of view. Continual advances in medicine and technology necessitate constant reevaluation of the air-conditioning needs of hospital and medical facilities. The application of air conditioning to health facilities presents many problems not encountered in the usual comfort air conditioning design. Hospital air conditioning assumes a more important role than just the promotion of comfort. Studies show that patients in controlled environment generally have more rapid physical improvement than do those in uncontrolled environment. Air quality at hospitals needs special precautions during design and maintenance stage to prevent infections from spreading. 50% of all illnesses are either caused by, or aggravated by, polluted indoor air. The main objective of this paper is to critically review and summarize the available information about IAQ particularly in health care industries. Symptoms of poor IAQ in a building, contaminants causing poor IAQ, features of HVAC systems for a hospital for better IAQ are briefly discussed in this paper. Strategies to improve indoor air quality in hospitals and the current international research to improve indoor air quality are reported in this paper. Based on the extensive interactions with different stake holders of a hospital it is concluded that maintenance of proper indoor quality in a hospital needs meticulous team work among the various members of the hospital at various stages .

Fisk Journal Energy and Buildings Volume 61 Pagination 378-386 Date Published 06/2013 Keywords apartments, buildings, costs, energy, indoor environmental quality, Protocol, retrofits, Selection Abstract The current focus on building energy retrofit provides an opportunity to simultaneously improve indoor environmental quality (IEQ). Toward this end, we developed a protocol for selecting packages of retrofits that both save energy and improve IEQ in apartments. The protocol specifies the methodology for selecting retrofits from a candidate list while addressing expected energy savings, IEQ impacts, and costs in an integrated manner. Interviews, inspections and measurements are specified to collect the needed input information. The protocol was applied to 17 apartments in three buildings in two different climates within California. Diagnostic measurements and surveys conducted before and after retrofit implementation indicate enhanced apartment performance.

The research literature provides strong evidence that characteristics of buildings and their indoor environments influence the prevalence of several adverse health effects. These include communicable respiratory disease (e.g., common colds and influenza), allergy and asthma symptoms, and acute sick building syndrome (SBS) symptoms such as headaches, and irritation of the eyes, nose, throat, and skin. For example, in six studies, the number of respiratory illnesses in building occupants varied by a factor of 1.2 to

Participant evaluation results for two indoor air quality studies  

SciTech Connect

After two surveys for indoor air pollutants (radon and other chemicals) the homeowners were surveyed for their reactions. The results of these participant evaluation surveys, assuming that the participants that responded to the survey were representative, indicate that homeowners will accept a significant level of monitoring activity as part of an indoor air quality field study. Those participants completing surveys overwhelmingly enjoyed being in the studies and would do it again. We believe that the emphasis placed on positive homeowner interactions and efforts made to inform participants throughout our studies were positive factors in this result. There was no substantial differences noted in the responses between the 70-house study, which included a homeowner compensation payment of $100, and the 300-house study, which did not include a compensation payment. These results provide encouragement to conduct future complex, multipollutant indoor air quality studies when they are scientifically sound and cost effective.

Shendell Conference Name Proceedings of Sustainable Buildings 2005 Conference Pagination 1432-1437 Conference Location Tokyo, Japan, September 27-29, 2005 Abstract The factory-built relocatable classroom (RC) is a dominant force in the school facility construction industry in the United States (U.S.) and elsewhere. It is estimated that there are approximately 650,000 RCs currently occupied in the U.S., housing about 16 million students. RCs receive public attention due to complaints about poor indoor environmental quality (IEQ). Both measured data and anecdotal evidence in California have suggested excessive acoustical noise from heating, ventilation, and air conditioning (HVAC) equipment as a central factor leading to degraded IEQ. In the U.S., RCs are typically equipped with unitary exterior wall-mount HVAC systems, and interior acoustical noise due to structural and airborne transmission can reach levels of about 58dB(A) with compressor cycling, under unoccupied conditions. Due to these noise levels teachers often simply choose to turn off the HVAC, leading to inadequate ventilation, as well as poor thermal conditioning, and thus to poor indoor air quality. Elevated levels of carbon dioxide and volatile organic compounds including formaldehyde are common. We discuss the acoustic component of our efforts to develop and test energy efficient HVAC systems that address the ventilation, controls, and acoustic requirements necessary to ensure high quality indoor environments in RCs

Indirect health effects of relative humidity in indoor environments  

SciTech Connect

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

High indoor radon variations and the thermal behavior of eskers  

Science Conference Proceedings (OSTI)

Measurements of indoor radon concentrations in houses built on the Pispala esker in the city of Tampere were taken. The objective was to find connections between indoor radon concentrations, esker topography, and meteorological factors. The results show that not only the permeable soil but also subterranean air-flows in the esker strongly affect the indoor radon concentrations. The difference in temperature between the soil air inside the esker and the outdoor air compels the subterranean air to stream between the upper and lower esker areas. In winter, the radon concentrations are amplified in the upper esker areas where air flows out from the esker. In summer, concentrations are amplified in certain slope zones. In addition, wind direction affects the soil air and indoor radon concentrations when hitting the slopes at right angles. Winter-summer concentration ratios are typically in the range of 3-20 in areas with amplified winter concentration, and 0.1-0.5 in areas with amplified summer concentrations. A combination of winter and summer measurements provides the best basis for making mitigation decisions. On eskers special attention must be paid to building technology because of radon. 9 refs., 7 figs., 1 tab.

Indoor air quality measurements in energy efficient buildings  

DOE Green Energy (OSTI)

The Energy Efficient Buildings Program of the Lawrence Berkeley Laboratory (LBL) has designed and fabricated a mobile laboratory for research and development studies of ventilation requirements and energy utilization in residential and commercial buildings. The Energy Efficient Buildings (EEB) Mobile Laboratory is used in studies of indoor air quality in buildings before and after energy conservation retrofits and in new buildings incorporating energy efficient designs. Indoor air quality measurements have been conducted in residential buildings and work in progress includes indoor air quality monitoring in schools, hospitals, and energy efficient residential buildings. The monitoring program includes measurement of CO, CO/sub 2/, SO/sub 2/, NO, NO/sub 2/, O/sub 3/, infiltration rate (tracer gas technique), and aerosol size distribution on a continuous basis. Total and respirable-fraction particulate samples are collected on membrane filter media for analysis by x-ray fluorescence (XRFA), photoelectron spectroscopy (ESCA), proton activation analysis (PAA), combustion, and wet-chemistry techniques for the determination of particulate elemental composition (S, N, C, etc.) and ionic species such as SO/sub 4//sup 2 -/, NO/sub 3//sup -/, and NH/sub 4//sup +/. Results of the initial phases of this program indicate that the concentrations of some gaseous and respirable particulate air pollutants in specific indoor environments exceed those levels commonly found in the outdoor urban air environment.

Impacts of Mixing on Acceptable Indoor Air Quality in Homes

Impacts of Mixing on Acceptable Indoor Air Quality in Homes Impacts of Mixing on Acceptable Indoor Air Quality in Homes Title Impacts of Mixing on Acceptable Indoor Air Quality in Homes Publication Type Journal Article LBNL Report Number LBNL-3048E Year of Publication 2010 Authors Sherman, Max H., and Iain S. Walker Journal HVAC & Research Journal Keywords air distribution, indoor air quality, mechanical ventilation, mixing, other, resave, residential ventilation, ventilation effectiveness Abstract Ventilation reduces occupant exposure to indoor contaminants by diluting or removing them. In a multi-zone environment such as a house, every zone will have different dilution rates and contaminant source strengths. The total ventilation rate is the most important factor in determining occupant exposure to given contaminant sources, but the zone-specific distribution of exhaust and supply air and the mixing of ventilation air can play significant roles. Different types of ventilation systems will provide different amounts of mixing depending on several factors such as air leakage, air distribution system, and contaminant source and occupant locations. Most U.S. and Canadian homes have central heating, ventilation, and air conditioning systems, which tend to mix the air; thus, the indoor air in different zones tends to be well mixed for significant fractions of the year. This article reports recent results of investigations to determine the impact of air mixing on exposures of residential occupants to prototypical contaminants of concern. We summarize existing literature and extend past analyses to determine the parameters than affect air mixing as well as the impacts of mixing on occupant exposure, and to draw conclusions that are relevant for standards development and for practitioners designing and installing home ventilation systems. The primary conclusion is that mixing will not substantially affect the mean indoor air quality across a broad population of occupants, homes, and ventilation systems, but it can reduce the number of occupants who are exposed to extreme pollutant levels. If the policy objective is to minimize the number of people exposed above a given pollutant threshold, some amount of mixing will be of net benefit even though it does not benefit average exposure. If the policy is to minimize exposure on average, then mixing air in homes is detrimental and should not be encouraged. We also conclude that most homes in the US have adequate mixing already, but that new, high-performance homes may require additional mixing. Also our results suggest that some differentiation should be made in policies and standards for systems that provide continuous exhaust, thereby reducing relative dose for occupants overall

Investigative Tools and Techniques for Indoor Air Quality Studies  

E-Print Network (OSTI)

Indoor air quality problems are diverse and often complex. Adverse indoor air quality problems can exist which create symptomatic conditions for building occupants. Often, the exact cause, or causes, of the substandard indoor air quality are unknown. Therefore, an investigative approach must usually be taken to identify the source(s) of the air quality problem, and if present, air contaminant concentrations. As the general public becomes more aware of the problems associated with poor indoor air quality conditions, an associated increase in air quality evaluation requests can be expected. This paper discusses some of the various investigative tools and techniques that can be utilized to identify air quality contaminants when performing an indoor air quality evaluation. These investigative tools and techniques can be used to develop a site specific list of possible contaminants and their sources, and can then be used to determine which contaminants are, in fact, present in adverse concentrations. Some of the investigative tools and techniques to be discussed in this paper include the following: visual inspections and site observations, information searches, review of building construction, review of ventilation systems, interviews, low and high volume sampling pumps, flow and oxygen meters, portable photoionization and flame ionization detectors (PID & FID), various types of vapor detector tubes, and gas chromatograph/mass spectrophotometer (GC/MS) analysis. This paper will be an introductory overview of the above listed investigative tools and techniques. The paper's attempt is to acquaint the reader with these investigative tools and techniques, and how they can assist the reader in an air quality evaluation.

Airflow and Pollutant Transport Modeling In Indoor and Built Environment Airflow and Pollutant Transport Modeling In Indoor and Built Environment Speaker(s): Teshome Edae Jiru Date: October 12, 2009 - 12:12pm Location: 90-3122 Computer simulation is based on mathematical models developed mostly from theoretical science and helps for studying and prediction of the behavior of engineered systems. The advantages of computer simulation are the ease of varying the desired parameters to investigate various possible design scenarios, explore new theories, and design new experiments to test these theories. It also provides detailed information and serves as a powerful alternative to experimental science and observation when phenomena are not observable or when measurements are impractical or too expensive. This seminar presents the different types of mechanistic modeling approaches

4 4 Subsurface Gasoline Contamination: An Indoor Air Quality Field Study Schematic of soil-gas and contaminant transport into a slab-on-grade building at a former service station site. Three effects are illustrated that can contribute to reducing the amount of contaminant available for entry into the building: biodegradation by soil microorganisms; a layer of soil that limits diffusive movement of the contaminant; and wind-driven ventilation of the soil below the building. Not illustrated are the effects of ventilation on contaminant concentrations inside the building. The transport of soil-gas-borne contaminants into buildings has been documented as a significant source of human exposure to some pollutants indoors; one example is radon, which has received widespread public

Indoor-outdoor air leakage of apartments and commercial buildings. Indoor-outdoor air leakage of apartments and commercial buildings. Title Indoor-outdoor air leakage of apartments and commercial buildings. Publication Type Report Year of Publication 2006 Authors Price, Phillip N., Arman Shehabi, Wanyu R. Chan, and Ashok J. Gadgil Publisher Lawrence Berkeley National Laboratory Abstract We compiled and analyzed available data concerning indoor-outdoor air leakage rates and building leakiness parameters for commercial buildings and apartments. We analyzed the data, and reviewed the related literature, to determine the current state of knowledge of the statistical distribution of air exchange rates and related parameters for California buildings, and to identify significant gaps in the current knowledge and data. Very few data were found from California buildings, so we compiled data from other states and some other countries. Even when data from other developed countries were included, data were sparse and few conclusive statements were possible. Little systematic variation in building leakage with construction type, building activity type, height, size, or location within the u.s. was observed. Commercial buildings and apartments seem to be about twice as leaky as single-family houses, per unit of building envelope area. Although further work collecting and analyzing leakage data might be useful, we suggest that a more important issue may be the transport of pollutants between units in apartments and mixed-use buildings, an under-studied phenomenon that may expose occupants to high levels of pollutants such as tobacco smoke or dry cleaning fumes.

The Airborne Metagenome in an Indoor Urban Environment  

SciTech Connect

The indoor atmosphere is an ecological unit that impacts on public health. To investigate the composition of organisms in this space, we applied culture-independent approaches to microbes harvested from the air of two densely populated urban buildings, from which we analyzed 80 megabases genomic DNA sequence and 6000 16S rDNA clones. The air microbiota is primarily bacteria, including potential opportunistic pathogens commonly isolated from human-inhabited environments such as hospitals, but none of the data contain matches to virulent pathogens or bioterror agents. Comparison of air samples with each other and nearby environments suggested that the indoor air microbes are not random transients from surrounding outdoor environments, but rather originate from indoor niches. Sequence annotation by gene function revealed specific adaptive capabilities enriched in the air environment, including genes potentially involved in resistance to desiccation and oxidative damage. This baseline index of air microbiota will be valuable for improving designs of surveillance for natural or man-made release of virulent pathogens.

Optimal Indoor Air Temperature Considering Energy Savings and Thermal Comfort in the Shanghai Area  

E-Print Network (OSTI)

Indoor air temperature is the most important control parameter in air conditioning systems. It not only impacts the thermal comfort of occupants, but also also greatly affects the energy consumption in air conditioning systems. The lower the indoor air temperature is in summer or the higher the indoor temperature is in winter, the more energy the air conditioning system will consume. For the sake of energy conservation, the indoor air should be set as high as possible in summer and as low as possible in winter. Meanwhile, indoor thermal comfort should be considered. This paper will establish the optimal indoor air temperature for an air-conditioning system aiming at both energy savings and thermal comfort in the Shanghai area, based on the PMV equation and extensive field investigation.

Lunden, Brett C. Singer, Beverly K. Coleman, Alfred T. Hodgson, Charles J. Weschler, and William W. Nazaroff Journal Environmental Science and Technology Volume 40 Start Page Chapter Pagination 4421-4428 Abstract Ozone-driven chemistry is a major source of indoor secondary pollutants of health concern. This study investigates secondary air pollutants formed from reactions between constituents of household products and ozone. Gas-phase product emissions were introduced along with ozone at constant rates into a 198-L Teflon-lined reaction chamber. Gas-phase concentrations of reactive terpenoids and oxidation products were measured. Formaldehyde was a predominant oxidation byproduct for the three studied products, with yields under most conditions of 20-30% with respect to ozone consumed. Acetaldehyde, acetone, glycolaldehyde, formic acid and acetic acid were each also detected for two or three of the products. Immediately upon mixing of reactants, a scanning mobility particle sizer detected particle nucleation events that were followed by a significant degree of ultrafine particle growth. The production of secondary gaseous pollutants and particles depended primarily on the ozone level and was influenced by other parameters such as the air-exchange rate. Hydroxyl radical concentrations in the range 0.04-200 × 105 molecules cm-3 were measured. OH concentrations were observed to vary strongly with residual ozone level in the chamber, which was in the range 1 - 25 ppb, as is consistent with expectations from a simplified kinetic model. In a separate test, we exposed the dry residue of two products to ozone in the chamber and observed the formation of gas-phase and particle-phase secondary oxidation products

Integrating Human Indoor Air Pollutant Exposure within Life Cycle Impact Assessment  

SciTech Connect

Neglecting health effects from indoor pollutant emissions and exposure, as currently done in Life Cycle Assessment (LCA), may result in product or process optimizations at the expense of workers? or consumers? health. To close this gap, methods for considering indoor exposure to chemicals are needed to complement the methods for outdoor human exposure assessment already in use. This paper summarizes the work of an international expert group on the integration of human indoor and outdoor exposure in LCA, within the UNEP/SETAC Life Cycle Initiative. A new methodological framework is proposed for a general procedure to include human-health effects from indoor exposure in LCA. Exposure models from occupational hygiene and household indoor air quality studies and practices are critically reviewed and recommendations are provided on the appropriateness of various model alternatives in the context of LCA. A single-compartment box model is recommended for use as a default in LCA, enabling one to screen occupational and household exposures consistent with the existing models to assess outdoor emission in a multimedia environment. An initial set of model parameter values was collected. The comparison between indoor and outdoor human exposure per unit of emission shows that for many pollutants, intake per unit of indoor emission may be several orders of magnitude higher than for outdoor emissions. It is concluded that indoor exposure should be routinely addressed within LCA.

Influence of local geology on the concentration of indoor radon in Maryland  

Science Conference Proceedings (OSTI)

Approximately 58,000 indoor radon measurements are available for homes in Maryland. A comparative study between compilations of activated-charcoal and alpha-track measurements of indoor radon in zip-code-size geographic areas indicated that both of these methods are useful and are equally able to estimate regional indoor radon. Indoor radon measurements compiled according to zip code areas can be used to create state-size radon hazard maps. In Maryland the area with the highest indoor radon (mostly composed of zip code areas that average over 8 pCi/L) is the western half of the Piedmont Province and the eastern side of the Coastal Plain Province. The eastern half of the Piedmont and the eastern half of the Valley and Ridge mostly have intermediate and high indoor radon levels (4--8 and >8 pCi/L). The Blue Ridge, western side of the Valley and Ridge, and Plateau Province each has relatively few zip code areas, but the data suggest a range from low to high indoor radon levels. The western side of the Coastal Plain has the lowest indoor radon (most of the zip code areas average less than 4 pCi/L).

Indoor Radon and Its Decay Products: Concentrations, Causes, and Control Strategies  

SciTech Connect

This report is an introduction to the behavior of radon 222 and its decay products in indoor air. This includes review of basic characteristics of radon and its decay products and of features of the indoor environment itself, all of which factors affect behavior in indoor air. The experimental and theoretical evidence on behavior of radon and its decay products is examined, providing a basis for understanding the influence of geological, structural, and meteorological factors on indoor concentrations, as well as the effectiveness of control techniques. We go on to examine three important issues concerning indoor radon. We thus include (1) an appraisal of the concentration distribution in homes, (2) an examination of the utility and limitations of popular monitoring techniques and protocols, and (3) an assessment of the key elements of strategies for controlling radon levels in homes.

Using LED Lighting for Ubiquitous Indoor Wireless Networking  

E-Print Network (OSTI)

Abstract—Wireless networking is currently dominated by radio frequency (RF) techniques. However, the soon-to-be ubiquity of LED-based lighting motivated by significant energy savings provides an opportunistic deployment of widespread free-space optical (FSO) communications. LEDbased network transceivers have a variety of competitive advantages over RF including high bandwidth density, security, energy consumption, and aesthetics. They also use a highly reusable unregulated part of the spectrum (visible light). In this paper we describe results from a pilot project to demonstrate the viability of an optical free-space visible light transceiver as a basis for indoor wireless networking. Inexpensive, commercial, off-the shelf LEDs and photodiodes we used to construct two prototypes; a simplex channel as expected as a component of an asymmetric/hybrid RF-FSO system, and a full-duplex channel demonstrating the ability to isolate multiple channels. On— off keying (OOK) was applied without observable flicker in the target modulation ranges. Results indicate the viability of creating inexpensive FSO transceivers that might be embedded in commercial lighting products to support ceiling-to-floor distances of approximately 3m. Index Terms—Wireless networking, indoor communications, free-space optical communications, visible light LED, modulation, OOK, FSO. 1 I.

Scoring dynamics across professional team sports: tempo, balance and predictability  

E-Print Network (OSTI)

Despite growing interest in quantifying and modeling the scoring dynamics within professional sports games, relative little is known about what patterns or principles, if any, cut across different sports. Using a comprehensive data set of scoring events in nearly a dozen consecutive seasons of college and professional (American) football, professional hockey, and professional basketball, we identify several common patterns in scoring dynamics. Across these sports, scoring tempo---when scoring events occur---closely follows a common Poisson process, with a sport-specific rate. Similarly, scoring balance---how often a team wins an event---follows a common Bernoulli process, with a parameter that effectively varies with the size of the lead. Combining these processes within a generative model of gameplay, we find they both reproduce the observed dynamics in all four sports and accurately predict game outcomes. These results demonstrate common dynamical patterns underlying within-game scoring dynamics across prof...

The databases searched were Medline, Toxline and TOXNET. Searches were performed using a variety of strategies. Combinations of the following keywords were used: carbon, monoxide, accidental, residential, occult, diagnosis, misdiagnosis, heating, furnace, and indoor. The literature was searched from 1966 to the present. Over 1000 references were identified and summarized using the following abbreviations: The major findings of the search are: (1) Acute and subacute carbon monoxide exposures result in a large number of symptoms affecting the brain, kidneys, respiratory system, retina, and motor functions. (2) Acute and subacute carbon monoxide (CO) poisonings have been misdiagnosed on many occasions. (3) Very few systematic investigations have been made into the frequency and consequences of carbon monoxide poisonings.

Impacts of Contaminan t Storage on Indoor Air Quality: Model Development Impacts of Contaminan t Storage on Indoor Air Quality: Model Development Title Impacts of Contaminan t Storage on Indoor Air Quality: Model Development Publication Type Journal Article LBNL Report Number LBNL-6114E Year of Publication 2013 Authors Sherman, Max H., and Erin L. Hult Journal Atmospheric Environment Volume 72 Start Page 41 Pagination 41-49 Date Published 01/2013 Keywords Buffering capacity, formaldehyde, moisture Abstract A first-order, lumped capacitance model is used to describe the buffering of airborne chemical species by building materials and furnishings in the indoor environment. The model is applied to describe the interaction between formaldehyde in building materials and the concentration of the species in the indoor air. Storage buffering can decrease the effect of ventilation on the indoor concentration, compared to the inverse dependence of indoor concentration on the air exchange rate that is consistent with a constant emission rate source. If the exposure time of an occupant is long relative to the time scale of depletion of the compound from the storage medium, however, the total exposure will depend inversely on the air exchange rate. This lumped capacitance model is also applied to moisture buffering in the indoor environment, which occurs over much shorter depletion timescales of the order of days. This model provides a framework to interpret the impact of storage buffering on time-varying concentrations of chemical species and resulting occupant exposure. Pseudo-steady state behavior is validated using field measurements. Model behavior over longer times is consistent with formaldehyde and moisture concentration measurements in previous studies.

Brown Journal Aerosol Science and Technology Volume 41 Pagination 639-654 Abstract Time-resolved fine particle concentrations of nitrate, sulfate, and black carbon were examined to assess the appropriateness of using regional data and calculated air exchange rates to model indoor concentrations of particles from outdoor sources. The data set includes simultaneous, sub-hourly aerosol composition measurements at three locations: a regional monitoring site in Fresno, California, inside of an unoccupied residence in Clovis, California, located 6 km northeast of the regional site, and immediately outside of this same residence. Indoor concentrations of PM2.5 nitrate, sulfate, and black carbon were modeled using varying sets of inputs to determine the influence of three factors on model accuracy: the constraints of the simplified indoor-outdoor model, measured versus modeled air exchange rates, and local versus regional outdoor measurements.

Indoor air quality issues related to the acquisition of conservation in commercial buildings  

Science Conference Proceedings (OSTI)

The quality of indoor air in commercial buildings is dependent on the complex interaction between sources of indoor pollutants, environmental factors within buildings such as temperature and humidity, the removal of air pollutants by air-cleaning devices, and the removal and dilution of pollutants from outside air. To the extent that energy conservation measures (ECMs) may affect a number of these factors, the relationship between ECMs and indoor air quality is difficult to predict. Energy conservation measures may affect pollutant levels in other ways. Conservation measures, such as caulking and insulation, may introduce sources of indoor pollutants. Measures that reduce mechanical ventilation may allow pollutants to build up inside structures. Finally, heating, ventilation, and air-conditioning (HVAC) systems may provide surface areas for the growth of biogenic agents, or may encourage the dissemination of pollutants throughout a building. Information about indoor air quality and ventilation in both new and existing commercial buildings is summarized in this report. Sick building syndrome and specific pollutants are discussed, as are broader issues such as ventilation, general mitigation techniques, and the interaction between energy conservation activities and indoor air quality. Pacific Northwest Laboratory (PNL) prepared this review to aid the Bonneville Power Administration (Bonneville) in its assessment of potential environmental effects resulting from conservation activities in commercial buildings. 76 refs., 2 figs., 19 tabs.

Guide to Energy-Efficient Ventilation Methods for Acceptable Levels of Indoor Air Quality Levels in Commercial Buildings  

Science Conference Proceedings (OSTI)

Indoor air quality is important in commercial buildings to maintain employee health, well-being, and productivity and avoid employer liability. The most common method to improve indoor air quality in commercial buildings is to use outside ventilation air for dilution of the inside air. Unfortunately, the conditioning of outdoor ventilation air may result in increased energy use for cooling, dehumidification, and heating; and humid outdoor ventilation air also can degrade indoor air quality.

Energy Saving and Good Quality Lighting for Indoor Applications  

E-Print Network (OSTI)

Artificial Lighting in indoor applications is throughout Europe in a lot of cases 20 years or older. That means there are luminaries, lamps and gear in use that are inefficient and so contributing to environmental pollution due to high energy use. These installations one can find in public buildings, offices and industry halls. In offices 75% of the existing installations are old-fashioned and consumes too much energy. A tremendous high potential for energy savings is available. In the past years more and more efficient lighting solutions for these areas where developed. An increase in efficiency but at the same time also in quality of lighting took place. This increase of efficiency can be realized in different ways. In e.g. offices, new fluorescent lamps TL5 with extremely high lamp efficacies, silver-coated aluminum lamellae optics for high luminares efficiency, as well as highly efficient electronic gear take care that the energy consumption is decreasing up to 40%, while the light quality is improving. Latest developments in lighting controls, daylight regulation and presence detection, again reduces the energy bill by another up to 50%.

Indoor-Outdoor Air Leakage of Apartments and Commercial Buildings  

SciTech Connect

We compiled and analyzed available data concerning indoor-outdoor air leakage rates and building leakiness parameters for commercial buildings and apartments. We analyzed the data, and reviewed the related literature, to determine the current state of knowledge of the statistical distribution of air exchange rates and related parameters for California buildings, and to identify significant gaps in the current knowledge and data. Very few data were found from California buildings, so we compiled data from other states and some other countries. Even when data from other developed countries were included, data were sparse and few conclusive statements were possible. Little systematic variation in building leakage with construction type, building activity type, height, size, or location within the u.s. was observed. Commercial buildings and apartments seem to be about twice as leaky as single-family houses, per unit of building envelope area. Although further work collecting and analyzing leakage data might be useful, we suggest that a more important issue may be the transport of pollutants between units in apartments and mixed-use buildings, an under-studied phenomenon that may expose occupants to high levels of pollutants such as tobacco smoke or dry cleaning fumes.

Mercury concentrations in Maine sport fishes  

Science Conference Proceedings (OSTI)

To assess mercury contamination of fish in Maine, fish were collected from 120 randomly selected lakes. The collection goal for each lake was five fish of the single most common sport fish species within the size range commonly harvested by anglers. Skinless, boneless fillets of fish from each lake were composited, homogenized, and analyzed for total mercury. The two most abundant species, brook trout Salvelinus fontinalis and smallmouth bass Micropterus dolomieu, were also analyzed individually. The composite fish analyses indicate high concentrations of mercury, particularly in large and long-lived nonsalmonid species. Chain pickerel Esox niger, smallmouth bass, largemouth bass Micropterus salmoides, and white perch Morone americana had the highest average mercury concentrations, and brook trout and yellow perch Perca flavescens had the lowest. The mean species composite mercury concentration was positively correlated with a factor incorporating the average size and age of the fish. Lakes containing fish with high mercury concentrations were not clustered near known industrial or population centers but were commonest in the area within 150 km of the seacoast, reflecting the geographical distribution of species that contained higher mercury concentrations. Stocked and wild brook trout were not different in length or weight, but wild fish were older and had higher mercury concentrations. Fish populations maintained by frequent introductions of hatchery-produced fish and subject to high angler exploitation rates may consist of younger fish with lower exposure to environmental mercury and thus contain lower concentrations than wild populations.

Do indoor environments in schools influence student performance? A review of the literature  

SciTech Connect

Limited research is available on potential adverse effects of school environments on academic performance, despite strong public concern. We examine the scientific evidence relevant to this relationship by reviewing available research relating schools and other indoor environments to human performance or attendance. As a primary focus, we critically review evidence for direct relationships between indoor environmental quality (IEQ) in buildings and performance or attendance. As a secondary focus, we summarize, without critique, evidence on potential connections indirectly linking IEQ to performance or attendance: relationships between IEQ and health, between health and performance or attendance, and between attendance and performance. The most persuasive direct evidence showed increases in indoor concentrations of nitrogen dioxide and outdoor concentrations of several specific pollutants to be related to reduced school attendance. The most persuasive indirect evidence showed indoor dampness and microbiologic pollutants to be related to asthma and respiratory infections, which have in turn been related to reduced performance and attendance. Furthermore, a substantial scientific literature links poor IEQ (e.g., low ventilation rate, excess moisture or formaldehyde) with respiratory and other health effects in children and adults. Overall, evidence suggests that poor IEQ in schools can influence the performance and attendance of students, primarily through health effects from indoor pollutants. Also, inadequate IEQ in schools seems sufficiently common to merit strong public concern. Evidence is available to justify (1) immediate actions to protect IEQ in schools and (2) focused research on exposures, prevention, and causation, to better guide policies and actions on IEQ in schools.

Indoor environmental quality and ventilation in U.S. office buildings: A view of current issues  

Science Conference Proceedings (OSTI)

Much of the current focus on indoor environmental quality and ventilation in US office buildings is a response to sick building syndrome and occupant complaints about building-related health symptoms, poor indoor air quality, and thermal discomfort. The authors know that serious ``sick-building`` problems occur in a significant number of US office buildings and that a significant proportion of the occupants in many normal (non-sick) buildings report building-related health symptoms. Concerns about the health effects of environmental tobacco smoke have also focused attention on the indoor environment. The major responses of industry and governments, underway at the present time, are to restrict smoking in offices, to attempt to reduce the emissions of indoor pollutants, and to improve the operation of heating, ventilating and air conditioning (HVAC) systems. Better air filtration, improved HVAC commissioning and maintenance, and increased provisions for individual control of HVAC are some of the improvements in HVAC that are currently being, evaluated. In the future, the potential for improved productivity and reduced airborne transmission of infectious disease may become the major driving force for improved indoor environments.

Energy Efficient Ventilation for Maintaining Indoor Air Quality in Large Buildings  

E-Print Network (OSTI)

this paper was presented at the 3rd International Conference on Cold Climate Heating, Ventilating and Air-conditioning, Sapporo, Japan, November 2000 C. Y. Shaw Rsum Institute for Research in Construction, National Research Council Canada Achieving good indoor air quality in large residential and commercial buildings continues to be a top priority for owners, designers, building managers and occupants alike. Large buildings present a greater challenge in this regard than do smaller buildings and houses. The challenge is greater today because there are many new materials, furnishings, products and processes used in these buildings that are potential sources of air contaminants. There are three strategies for achieving acceptable indoor air quality: ventilation (dilution), source control and air cleaning/filtration. Of the three, the most frequently used strategy, and in most cases the only one available to building operators, is ventilation. Ventilation is the process of supplying outdoor air to an enclosed space and removing stale air from this space. It can control the indoor air quality by both diluting the indoor air with less contaminated outdoor air and removing the indoor contaminants with the exhaust air. Ventilation costs money because the outdoor air needs to be heated in winter and cooled in summer. To conserve energy, care must be taken to maximize the efficiency of the ventilation system. In this regard, a number of factors come into play

An indoor radon survey of the X-ray rooms of Mexico City hospitals  

SciTech Connect

This paper presents the results of measurements of indoor radon concentrations in the X-ray rooms of a selection of hospitals in the metropolitan area of Mexico City. The metropolitan area of Mexico City is Mexico's largest metropolitan area by population; the number of patients requiring the use of X-rays is also the highest. An understanding of indoor radon concentrations in X-ray rooms is necessary for the estimation of the radiological risk to which patients, radiologists and medical technicians are exposed. The indoor radon concentrations were monitored for a period of six months using nuclear track detectors (NTD) consisting of a closed-end cup system with CR-39 (Lantrack Registered-Sign ) polycarbonate as detector material. The indoor radon concentrations were found to be between 75 and 170 Bq m{sup -3}, below the USEPA-recommended indoor radon action level for working places of 400 Bq m{sup -3}. It is hoped that the results of this study will contribute to the establishment of recommended action levels by the Mexican regulatory authorities responsible for nuclear safety.

Work quality in the avocation of sports officiating as determined by selected members of the Texas Association of Sports Officials  

E-Print Network (OSTI)

The major purpose of this study was to examine work quality in the avocation of sports officiating, as determined by selected Texas High School Sports Officials. Specifically, the study investigated work quality indicators and the relationship between those indicators and the officials overall perception of the avocation of Texas High School sports officiating. To accomplish this purpose, two different survey methods were used. A convenience sample of 125 sports officials participated in a qualitative questionnaire. Usable data was obtained from 114 officials. Utilizing both the qualitative research and information gathered from relevant literature, a web-based survey was constructed and used to contact selected members of the Texas Association of Sports Officials. A total of 1075 responses were received. The web-based instrument integrated items related to basic demographic information, as outlined by Quinn and Staines, (1979). These items included, but were not limited to the following: gender, age, economic information, marital status, educational background, ethnic background and primary occupation. The instrument also investigated the following indicators of work quality: Vocational and avocational information, work environment, personal health and wellbeing, organizational and administrative support, and organizational commitment and officiating career outcomes. These indicators were further explored through the development of work quality constructs, which related to each indicator. The constructs were further studied as to their relationship with certain demographic information. The results of this study indicate that although there are significant work quality issues as they relate to sports officiating, the majority of the constructs studied showed little negative impact on the sports officials� perception of the work quality of the officiating avocation.

Assessment of Indoor Air Quality Benefits and Energy Costs of Mechanical Ventilation  

Science Conference Proceedings (OSTI)

Intake of chemical air pollutants in residences represents an important and substantial health hazard. Sealing homes to reduce air infiltration can save space conditioning energy, but can also increase indoor pollutant concentrations. Mechanical ventilation ensures a minimum amount of outdoor airflow that helps reduce concentrations of indoor emitted pollutants while requiring some energy for fan(s) and thermal conditioning of the added airflow. This work demonstrates a physics based, data driven modeling framework for comparing the costs and benefits of whole-house mechanical ventilation and applied the framework to new California homes. The results indicate that, on a population basis, the health benefits from reduced exposure to indoor pollutants in New California homes are worth the energy costs of adding mechanical ventilation as specified by ASHRAE Standard 62.2.This study determines the health burden for a subset of pollutants in indoor air and the costs and benefits of ASHRAE's mechanical ventilation standard (62.2) for new California homes. Results indicate that, on a population basis, the health benefits of new home mechanical ventilation justify the energy costs.

Evaluating Indoor Air Quality (IAQ) as Modifying Factor in Designing Public School Buildings in Jordan  

E-Print Network (OSTI)

The most fundamental goal in the design of educational facilities is to provide an environment that encourages learning achievement for students and teachers. Poor indoor air quality (IAQ) can negatively affect student health, comfort and performance that will eventually produce unacceptable learning environment. Poor IAQ can decrease a person's ability to perform specific mental tasks requiring concentration, calculation and memory. Therefore, schools should be designed, built and maintained in away to minimize and control the source of pollution. Around 29% of Jordanians occupy school buildings each day. A specific prototype building design was applied in the different locations of the country. This prototype could be appropriate for one location but it is not for the entire country that has diversity in climatic and environmental conditions The purpose of this research paper was to evaluate the indoor air quality in public school buildings in urban and rural area, through investigations of the causes and its effects on student health, comfort, and performance. Achieving healthy indoor air quality is a multifaceted a problem which can be arrived at by a comprehensive and interdisciplinary approach to the design, construction and operation of the school building. Results indicate that the prototype system used was not appropriate as healthy school design, and it did not take into consideration the indoor environmental factors as crucial issue in designing school buildings.

Gadgil, Tracy L. Thatcher, and Richard G. Sextro Journal Indoor Air Volume 14 Start Page Chapter Pagination 272-283 Abstract This paper reports on an investigation of the adequacy of Computational fluid dynamics (CFD), using a standard Reynolds Averaged Navier Stokes (RANS) model, for predicting dispersion of neutrally buoyant gas in a large indoor space. We used CFD to predict pollutant (dye) concentration profiles in a water filled scale model of an atrium with a continuous pollutant source. Predictions from the RANS formulation are comparable to an ensemble average of independent identical experiments. Model results were compared to pollutant concentration data in a horizontal plane from experiments in a scale model atrium. Predictions were made for steady-state (fully developed) and transient (developing) pollutant concentrations. Agreement between CFD predictions and ensemble averaged experimental measurements is quantified using the ratios of CFD-predicted and experimentally measured dye concentration at a large number of points in the measurement plane. Agreement is considered good if these ratios fall between 0.5 and 2.0 at all points in the plane. The standard k-epsilon two equation turbulence model obtains this level of agreement and predicts pollutant arrival time to the measurement plane within a few seconds. These results suggest that this modeling approach is adequate for predicting isothermal pollutant transport in a large room with simple geometry

Evidence of acid-base interactions between amines and model indoor surfaces Evidence of acid-base interactions between amines and model indoor surfaces by ATR-FTIR spectroscopy Title Evidence of acid-base interactions between amines and model indoor surfaces by ATR-FTIR spectroscopy Publication Type Journal Article LBNL Report Number LBNL-63480 Year of Publication 2007 Authors Destaillats, Hugo, Brett C. Singer, and Lara A. Gundel Journal Atmospheric Environment Volume 41 Start Page Chapter Pagination 3177-3181 ISBN Number 1352-2310 Keywords acid-base, cellulose, gypsum, nicotine, pyridine, sorption, surface materials Abstract Molecular associations of pyridine with cellulose and gypsum, surrogates for common indoor surface materials, were studied using an attenuated total reflection (ATR)-Fourier transform infrared (FTIR) spectrophotometric method. The purpose of this study was to gain insight into the molecular interactions of amines with well-characterized materials that affect their partitioning between indoor air and surfaces. The experimental results suggest the presence of at least two sorptive states for volatile and semivolatile amines, attributed to the chemisorbed species and to a more labile surface state (i.e., physisorbed pyridine). Both exhibited spectroscopic signatures corresponding to aromatic C-H stretching modes (2950-3100 cm-1) in the studied spectral region. Chemisorbed pyridine could be identified by the presence of additional IR signals in the N-H and O-H stretching region of the spectrum (2900-3600 cm-1). During desorption under a stream of N2, surface enrichment in the chemisorbed species was evidenced by a slower reduction of the absorbance of the broad band at 2900-3600 cm-1 in relation to the total pyridine absorbance change. This spectroscopic evidence for acid-base interactions between amines and surfaces is consistent with the desorption behavior observed in previous work for nicotine from model surfaces.

Study of the atmospheric chemistry of radon progeny in laboratory and real indoor atmospheres  

SciTech Connect

This report describes studies on the chemical and physical behavior of the [sup 218]Po atom immediately following its formation by the alpha decay of radon. Because small changes in size for activity in the sub-10 nm size range result in large changes in the delivered dose per unit exposure, this behavior must be understood if the exposure to radon progeny and its dose to the cells in the respiratory tract are to be fully assessed. The specific tasks of the controlled laboratory studies are to determine the formation rates of [center dot]OH radicals formed by the radiolysis of air following radon decay, to examine the formation of particles by the radiolytic oxidation of substances like SO[sub 2] ethylene, and H[sub 2]S to lower vapor pressure compounds and determine the role of gas phase additives such as H[sub 2]O and NH[sub 3] in determining the particle size, to measure the rate of ion-induced nucleation using a thermal diffusion cloud chamber, and to measure the neutralization rate of [sup 218]Po[sub x][sup +] in O[sub 2] at low radon concentrations. Tasks of the exposure studies in occupied indoor spaces are to initiate measurements of the activity size distributions in actual homes with occupants present so that the variability of the indoor activity size distributions can be assessed with respect to indoor aerosol sources and general lifestyle variations of the occupants, to initiate a prospective study of the utility of measurement of deposited [sup 210]Pb embedded in glass surfaces as a measure of the long-term, integrated exposure of the population to radon, and to develop the methodology to determine the hygroscopicity of the indoor aerosol so that the changes in deposition efficiency of the radioactive indoor aerosol with hygroscopic growth in the respiratory tract can be assessed.

Study of the atmospheric chemistry of radon progeny in laboratory and real indoor atmospheres  

SciTech Connect

This report covers the second year of the 28 month grant current grant to Clarkson University to study the chemical and physical behavior of the polonium 218 atom immediately following its formation by the alpha decay of radon. Because small changes in size for activity result in large changes in the delivered dose per unit exposure, this behavior must be understood if the exposure to radon progeny and it dose to the cells in the respiratory tract are to be fully assessed. Two areas of radon progeny behavior are being pursued; laboratory studies under controlled conditions to better understand the fundamental physical and chemical process that affect the progeny's atmospheric behavior and studies in actual indoor environments to develop a better assessment of the exposure of the occupants of that space to the size and concentration of the indoor radioactive aerosol. This report describes the progress toward achieving these objectives.

Residential electricity use, wood use, and indoor temperature; An econometric model  

DOE Green Energy (OSTI)

A lagged-dependent variable, simultaneous-equation system model of residential electricity use for space heating and other uses, wood use, and indoor temperature is presented. The model is specified by means of a five-element model-building framework developed at Oak Ridge National Laboratory. Data were collected from 100 households that had end-use metering installed as part of the Hood River Conservation Project. The most important finding is that the dependent variables are relatively independent of each other. Model results also indicate that houses with central heating use more electricity for space heating and that households with favorable attitudes toward conservation prefer lower indoor temperatures and use less energy.

Hodgson, and William J. Fisk Keywords market sectors, technologies Abstract Mock Critical Peak Pricing (CPP) events were implemented in a Target retail store in the San Francisco Bay Area by shutting down some of the building's packaged rooftop air-handling units (RTUs). Measurements were made to determine how this load shedding strategy would affect the outdoor air ventilation rate and the concentrations of volatile organic compounds (VOCs) in the sales area. Ventilation rates prior to and during load shedding were measured by tracer gas decay on two days. Samples for individual VOCs, including formaldehyde and acetaldehyde, were collected from several RTUs in the morning prior to load shedding and in the late afternoon. Shutting down a portion (three of 11 and five of 12, or 27 and 42%) of the RTUs serving the sales area resulted in about a 30% reduction in ventilation, producing values of 0.50-0.65 air changes per hour. VOCs with the highest concentrations (>10 μg/m3) in the sales area included formaldehyde, 2-butoxyethanol, toluene and decamethylcyclopentasiloxane. Substantial differences in concentrations were observed among RTUs. Concentrations of most VOCs increased during a single mock CPP event, and the median increase was somewhat higher than the fractional decrease in the ventilation rate. There are few guidelines for evaluating indoor VOC concentrations. For formaldehyde, maximum concentrations measured in the store during the event were below guidelines intended to protect the general public from acute health risks.

Indoor Conditions Study and Impact on the Energy Consumption for a Large Commercial Building  

E-Print Network (OSTI)

This study is focused on the analysis of indoor conditions for a new commercial building that will be constructed in an East-European country. Based on the initial HVAC design parameters the surface of the building was divided in thermal zones that were studied using dynamic simulations. The article provides interesting insights of the building indoor conditions (summer/winter comfort), humidity, air temperature, mean operative temperature and energy consumption using hourly climate data. A dynamic variation of the PMV (Predicted Mean Vote Index) was obtained for different thermal zones of the building (retails stores, mall circulation, corridors) and in most of the cases the acceptable values of plus/minus 0.5 are exceeded. Among the most important energy efficiency measures it is mentioned a decrease of the heating set point temperature, increase of the walls and roof thermal resistance and the use of a heat recovery on the ventilation system. In this work it is demonstrated how simple measures can enhance the indoor conditions and reduce the energy consumption for this kind of construction.

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

SciTech Connect

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

Lunden, Tracy L. Thatcher, David Littlejohn, Thomas W. Kirchstetter, Susanne V. Hering, Richard G. Sextro, and Nancy J. Brown Abstract The prevalence of relocatable classrooms (RCs) at schools is rising due to federal and state initiatives to reduce K-3 class size, and limited capital resources. Concerns regarding inadequate ventilation and indoor air and environmental quality (IEQ) in RCs have been raised. Adequate ventilation is an important link between improved IEQ and energy efficiency for schools. Since students and teachers spend the majority of a 7-8 hour school day inside classrooms, indoor contaminant concentrations are assumed to drive personal school-day exposures. We conducted a demonstration project in new relocatable classrooms (RCs) during the 2001-02 school year to address these issues. Four new 24' x 40' (960 ft2) RCs were constructed and sited in pairs at an elementary school campus in each of two participant school districts (SD) in Northern California. Each RC was equipped with two heating, ventilation, and air conditioning (HVAC) systems, one per module. The two HVAC systems were a standard heat pump with intermittent 25-50% outdoor air ventilation and an energy-efficient advanced system, based on indirect-direct evaporative cooling with an integrated natural gas-fired hydronic heating loop and improved particle filtration, providing continuous 100% outdoor air ventilation at = 15 ft3 min-1 occupant-1. Alternate carpets, wall panels, and ceiling panels were installed in two classrooms -- one in each pair -- based on the results of a laboratory study of VOC emissions from standard and alternate materials.

Geographical, spatial, and temporal distributions of multiple indoor air pollutants in four Chinese provinces  

Science Conference Proceedings (OSTI)

Exposure to indoor air pollution from household energy use depends on fuel, stove, housing characteristics, and stove use behavior. Three important indoor air pollutants - respirable particles (RPM), carbon monoxide (CO), and sulfur dioxide (SO{sub 2}) were monitored for a total of 457 household-days in four poor provinces in China (Gansu, 129 household-days; Guizhou, 127 household-days; Inner Mongolia, 65 household-days; and Shaanxi, 136 household-days), in two time intervals during the heating season to investigate spatial and temporal patterns of pollution. The two provinces where biomass is the primary fuel (Inner Mongolia and Gansu) had the highest RPM concentrations (719 {mu}g/m{sup 3} in the single cooking/living/bedroom in Inner Mongolia in December and 351-661 {mu}g/m{sup 3} in different rooms and months in Gansu); lower RPM concentration were observed in the primarily coal-burning provinces of Guizhou and Shaanxi (202-352 {mu}g/m{sup 3} and 187-361 {mu}g/m{sup 3} in different rooms and months in Guizhou and Shaanxi, respectively). Inner Mongolia and Gansu also had higher CO concentrations. Among the two primarily coal-burning provinces, Guizhou had lower concentrations of CO than Shaanxi. In the two coal-burning provinces, SO{sub 2} concentrations were substantially higher in Shaanxi than in Guizhou. Relative concentrations in different rooms and provinces indicate that in the northern provinces heating is an important source of exposure to indoor pollutants from energy use. Day-to-day variability of concentrations within individual households, although substantial, was smaller than variation across households. The implications of the findings for designing environmental health interventions in each province are discussed. 21 refs., 3 figs., 6 tabs.

Operation of Energy Efficient Residential Buildings Under Indoor Environmental Quality Requirements  

E-Print Network (OSTI)

This paper is devoted to the influence of Indoor Environmental Quality, [IEQ] requirements associated with occupation regimes on the criterion of energy demand s for HVAC (Heating, Ventilating and Air-Conditioning) central systems that were constructed for student hostels as a residential building in Cairo, Egypt. The paper focuses on the effects of occupation rate profiles with IEQ thermal parameters; (those are air dry-bulb temperatures, relative humidity, fresh air requirements, and local air velocities), on yearly energy demands. It is applied on, in-service, real project as a case study "10-Stories Hostel of 6000 m2 built-up area" that is utilized by Non-Local students as a transferred Egyptian citizens [ EC ] from different governorates. It was concluded that. during energy simulation, occupation rate schedules and operation profiles for each source of heat inside space shall simulate the reality. These profiles and schedules should be added to the local energy code as a guideline for designers. Although in this case study results from simulation task reach the real bills, but sometimes, with multi-use apartments there is another required schedule for the Pre-Action days. Those days before holidays and feasts on which the air conditioning system shall operate in a certain procedure for cleaning or scavenging. Another important issue is the effect of Effective Temperatures [ET] (Temperature for constant thermal sensations) that could implement to reduce the cooling capacity by increasing the room temperature against indoor relative humidity for the same comfort sensation. These two concepts will save 17% to 22% of the project total energy demand, In addition to introducing new design criteria for acceptable indoor conditions in the new rural developed zones in Egypt and similar regions.

The goal of this project is to develop a physically-based, semi-empirical model that describes the concentration of indoor concentration of PM-2.5 (particle mass that is less than 2.5 microns in diameter) and its sulfate, nitrate, organic and black carbon constituents, derived from outdoor sources. We have established the methodology and experimental plan for building the model. Experimental measurements in residential style houses, in Richmond and Fresno, California, are being conducted to provide parameters for and evaluation of this model. The model will be used to improve estimates of human exposures to PM-2.5 of outdoor origin. The objectives of this study are to perform measurement and modeling tasks that produce a tested, semi-mechanistic description of chemical species-specific and residential PM-2.5 arising from the combination of outdoor PM and gas phase sources (HNO{sub 3} and NH{sub 3}), and indoor gas phase (e.g. NH{sub 3}) sources. We specifically address how indoor PM is affected by differences between indoor and outdoor temperature and relative humidity. In addition, we are interested in losses of particles within the building and as they migrate through the building shell. The resulting model will be general enough to predict probability distributions for species-specific indoor concentrations of PM-2.5 based on outdoor PM, and gas phase species concentrations, meteorological conditions, building construction characteristics, and HVAC operating conditions. Controlled intensive experiments were conducted at a suburban research house located in Clovis, California. The experiments utilized a large suite of instruments including conventional aerosol, meteorological and house characterization devices. In addition, two new instruments were developed providing high time resolution for the important particulate species of nitrate, sulfate, and carbon as well as important gaseous species including ammonia and nitric acid. Important initial observations include the result that, with rare exceptions, there is virtually no nitrate found inside the house. This nitrate appears to dissociate into ammonia and nitric acid with the nitric acid quickly depositing out. Initial model development has included work on characterizing penetration and deposition rates, the dynamic behavior of the indoor/outdoor ratio, and predicting infiltration rates. Results from the exploration of the indoor/outdoor ratio show that the traditional assumption of steady state conditions does not hold in general. Many values of the indoor/outdoor ratio exist for any single value of the infiltration rate. Successful prediction of the infiltration rate from measured driving variables is important for extending the results from the Clovis house to the larger housing stock.

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

E-Print Network (OSTI)

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

Measurement and apportionment of radon source terms for modeling indoor environments  

SciTech Connect

During the present 2 1/2 year contract period, we have made significant Progress in modeling the source apportionment of indoor [sup 222]Rn and in [sup 222]Rn decay product dosimetry. Two additional areas were worked on which we believe are useful for the DOE Radon research Program. One involved an analysis of the research house data, grouping the hourly house [sup 222]Rn measurements into 2 day, 7 day and 90 day intervals to simulate the response of passive monitors. Another area requiring some attention resulted in a publication of 3 years of our indoor/outdoor measurements in a high-rise apartment. Little interest has been evinced in apartment measurements yet 20% of the US population lives in multiple-family dwellings, not in contact with the ground. These data together with a summary of all other published data on apartments showed that apartments have only about 50% greater [sup 222]Rn concentration than the measured outdoor [sup 222]Rn. Apartment dwellers generally represent a low risk group regarding [sup 222]Rn exposure. The following sections describe the main projects in some detail.

Ozone-surface interactions: Investigations of mechanisms, kinetics, mass transport, and implications for indoor air quality  

SciTech Connect

In this dissertation, results are presented of laboratory investigations and mathematical modeling efforts designed to better understand the interactions of ozone with surfaces. In the laboratory, carpet and duct materials were exposed to ozone and measured ozone uptake kinetics and the ozone induced emissions of volatile organic compounds. To understand the results of the experiments, mathematical methods were developed to describe dynamic indoor aldehyde concentrations, mass transport of reactive species to smooth surfaces, the equivalent reaction probability of whole carpet due to the surface reactivity of fibers and carpet backing, and ozone aging of surfaces. Carpets, separated carpet fibers, and separated carpet backing all tended to release aldehydes when exposed to ozone. Secondary emissions were mostly n-nonanal and several other smaller aldehydes. The pattern of emissions suggested that vegetable oils may be precursors for these oxidized emissions. Several possible precursors and experiments in which linseed and tung oils were tested for their secondary emission potential were discussed. Dynamic emission rates of 2-nonenal from a residential carpet may indicate that intermediate species in the oxidation of conjugated olefins can significantly delay aldehyde emissions and act as reservoir for these compounds. The ozone induced emission rate of 2-nonenal, a very odorous compound, can result in odorous indoor concentrations for several years. Surface ozone reactivity is a key parameter in determining the flux of ozone to a surface, is parameterized by the reaction probability, which is simply the probability that an ozone molecule will be irreversibly consumed when it strikes a surface. In laboratory studies of two residential and two commercial carpets, the ozone reaction probability for carpet fibers, carpet backing and the equivalent reaction probability for whole carpet were determined. Typically reaction probability values for these materials were 10{sup {minus}7}, 10{sup {minus}5}, and 10{sup {minus}5} respectively. To understand how internal surface area influences the equivalent reaction probability of whole carpet, a model of ozone diffusion into and reaction with internal carpet components was developed. This was then used to predict apparent reaction probabilities for carpet. He combines this with a modified model of turbulent mass transfer developed by Liu, et al. to predict deposition rates and indoor ozone concentrations. The model predicts that carpet should have an equivalent reaction probability of about 10{sup {minus}5}, matching laboratory measurements of the reaction probability. For both carpet and duct materials, surfaces become progressively quenched (aging), losing the ability to react or otherwise take up ozone. He evaluated the functional form of aging and find that the reaction probability follows a power function with respect to the cumulative uptake of ozone. To understand ozone aging of surfaces, he developed several mathematical descriptions of aging based on two different mechanisms. The observed functional form of aging is mimicked by a model which describes ozone diffusion with internal reaction in a solid. He shows that the fleecy nature of carpet materials in combination with the model of ozone diffusion below a fiber surface and internal reaction may explain the functional form and the magnitude of power function parameters observed due to ozone interactions with carpet. The ozone induced aldehyde emissions, measured from duct materials, were combined with an indoor air quality model to show that concentrations of aldehydes indoors may approach odorous levels. He shows that ducts are unlikely to be a significant sink for ozone due to the low reaction probability in combination with the short residence time of air in ducts.

Indoor Thermal Factors and Symptoms in Office Workers: Findings from the U.S. EPA BASE Study  

SciTech Connect

Some prior research in office buildings has associated higher indoor temperatures even within the recommended thermal comfort range with increased worker symptoms. We reexamined this relationship in data from 95 office buildings in the U.S. Environmental Protection Agency's Building Assessment Survey and Evaluation (BASE) Study. We investigated relationships between building-related symptoms and thermal metrics constructed from real-time measurements. We estimated odds ratios (ORs) and 95percent confidence intervals in adjusted logistic regression models with general estimating equations, overall and by season. Winter indoor temperatures spanned the recommended winter comfort range; summer temperatures were mostly colder than the recommended summer range. Increasing indoor temperatures, overall, were associated with increases in few symptoms. Higher winter indoor temperatures, however, were associated with increases in all symptoms analyzed. Higher summer temperatures, above 23oC, were associated with decreases in most symptoms. Humidity ratio, a metric of absolute humidity, showed few clear associations. Thus, increased symptoms with higher temperatures within the thermal comfort range were found only in winter. In summer, buildings were overcooled, and only the higher observed temperatures were within the comfort range; these were associated with decreased symptoms. Confirmation of these findings would suggest that thermal management guidelines consider health effects as well as comfort.

A triple hot-wire system for indoor air flow measurements  

SciTech Connect

The application of a home made, triple hot-wire system in indoor air flow measurements is presented. Both the anemometer and sensor have been developed at Athens University with the aim to provide a reliable, research tool of reasonable cost, simple construction, and satisfactory performance. All three velocity components above a threshold of 10 cm s{sup {minus}1} can be measured. The system is also equipped with two thermometers for measuring the mean and fluctuating air temperature and for providing a means of temperature compensation of the hot wires` signal. After evaluation of the system in the laboratory, it was used in the measurement of the velocity profile of flows driven by the temperature difference between two internal zones. The implied accuracy of the method allows for its integration with measurements of air volume exchange rates between internal zones, as estimated by tracer gas techniques.

Attributes of Indoor Environmental Quality to Earth-sheltered Building Design  

E-Print Network (OSTI)

This paper discusses the environmental attributes to underground building shape and configuration, materials, structures, use, maintenance, lighting, occupancy, and management. These criteria are hypothesized to be of more influences on the building environment in the cases of underground spaces than in the aboveground. The aim is to approach and link together the many recent architectural and engineering factors that affect indoor environmental quality (IEQ) as a contribution to the affordability and sustainability of present earth sheltered building design and development. To attain its goals, the study develops a conceptual micro-framework of healthy buildings' parameters and economic aspects for evaluating links between sustainable construction and outcomes of health, productivity, and affordability. The conclusion indicates the importance of integrating appropriate technologies into earth sheltered space design, while the recommendations conform with environmental organizations and policies' directives in both their short and long-term development plans to provide affordable and healthy earth sheltered interiors.

Air levels and mutagenicity of PM-10 in an indoor ice arena  

Science Conference Proceedings (OSTI)

The authors report here their results from a preliminary study to evaluate a methodology for surveying air quality by measuring concentrations of PM-10 and the corresponding concentrations of mutagenic activity. The PM-10 was collected, during several hockey games at an ice arena using an Indoor Air Sampling Impactor (IASI) developed by Marple et al. During the course of the study, smoking restrictions were imposed in the stadium and the impact of these restrictions on PM-10 levels was also evaluated. The mutagenic activities of solvent extracts of the PM-10 were determined using the microsuspension modification of the Samonella typhimurium/microsome test. Mutagenic activity has often been used as a rough index of exposure to potential carcinogens and mutagens and to help define their sources.

Automatic monitoring of selected indoor air parameters at three apartment complexes  

SciTech Connect

The impact of three different ventilation systems on the temperature and humidity of three similar apartment complexes is investigated in this study. Each complex has six apartments. The ventilation systems are: natural ventilation, mechanical exhaust ventilation, and mechanical supply and exhaust ventilation. The computer controlled data collection system measures the ventilation rate, relative humidity, indoor air temperature, wind speed, wind direction, outdoor temperature, and humidity. The air change rate depends mainly on the habits of the tenants. The mean air change rate of the houses was between 0.1 to 0.8 ac/h. Great daily variation of the air exchange was observed in the data. Negative correlation between relative humidity and ventilation was very significant in 27 out of 47 cases. Only two cases had very significant positive correlation between ventilation and humidity. Mechanical supply and exhaust ventilation have the greatest variation in ventilation/relative humidity relations.

Visual Localisation of Mobile Devices in an Indoor Environment under Network Delay Conditions  

E-Print Network (OSTI)

Current progresses in home automation and service robotic environment have highlighted the need to develop interoperability mechanisms that allow a standard communication between the two systems. During the development of the DHCompliant protocol, the problem of locating mobile devices in an indoor environment has been investigated. The communication of the device with the location service has been carried out to study the time delay that web services offer in front of the sockets. The importance of obtaining data from real-time location systems portends that a basic tool for interoperability, such as web services, can be ineffective in this scenario because of the delays added in the invocation of services. This paper is focused on introducing a web service to resolve a coordinates request without any significant delay in comparison with the sockets.

Indoor Air Nuclear, Biological, and Chemical Health Modeling and Assessment System  

SciTech Connect

Indoor air quality effects on human health are of increasing concern to public health agencies and building owners. The prevention and treatment of 'sick building' syndrome and the spread of air-borne diseases in hospitals, for example, are well known priorities. However, increasing attention is being directed to the vulnerability of our public buildings/places, public security and national defense facilities to terrorist attack or the accidental release of air-borne biological pathogens, harmful chemicals, or radioactive contaminants. The Indoor Air Nuclear, Biological, and Chemical Health Modeling and Assessment System (IA-NBC-HMAS) was developed to serve as a health impact analysis tool for use in addressing these concerns. The overall goal was to develop a user-friendly fully functional prototype Health Modeling and Assessment system, which will operate under the PNNL FRAMES system for ease of use and to maximize its integration with other modeling and assessment capabilities accessible within the FRAMES system (e.g., ambient air fate and transport models, water borne fate and transport models, Physiologically Based Pharmacokinetic models, etc.). The prototype IA-NBC-HMAS is designed to serve as a functional Health Modeling and Assessment system that can be easily tailored to meet specific building analysis needs of a customer. The prototype system was developed and tested using an actual building (i.e., the Churchville Building located at the Aberdeen Proving Ground) and release scenario (i.e., the release and measurement of tracer materials within the building) to ensure realism and practicality in the design and development of the prototype system. A user-friendly "demo" accompanies this report to allow the reader the opportunity for a "hands on" review of the prototype system's capability.

This article describes the HVAC systems design to keep Cleveland's new Gateway sports and entertainment complex comfortable. This magnificent new facility embraces the 42,000-seat Jacobs Field, with its natural grass playing surface, and the 21,000-seat Arena at Gateway (the official name will be announced at its August 1 opening). The Arena is the new home of the Cleveland Cavaliers NBA basketball team and the Lumberjacks IHL ice hockey team. Other events that will be held here include arena football, circuses, ice shows, and concerts. It is anticipated that the Arena will be in use in excess of 200 days a year for these and other functions. The ballpark and the arena are separated by Gateway Plaza, a large illuminated public space that also will be the site of various entertainment events. An air conditioned pedestrian bridge, approximately 0.7 miles in length, connects the Arena with the Regional Transit Authority's downtown rapid transit station. Other enclosed walkways connect the Arena with two parking garages (3,158 vehicles total) and the larger garage with Jacobs Field.

Seasonal Variation of Indoor Radon Concentration in the Tropics: Comparative studies between Kuala Lumpur, Malaysia and Kerala, India  

Science Conference Proceedings (OSTI)

The radiation dose received by man from indoor radon and its progeny is the largest at more than 50% of total dose received. The seasonal variation of indoor radon concentration in Kerala, India and Kuala Lumpur, Malaysia were studied. The Southwest coast of the Kerala state in India is known to have very high levels of natural background radiation owing to the rare earths rich monazite sand available in large amount. Kuala Lumpur, Malaysia used to be a famous tin mining area where it was done using open cast system. One-year measurements of radon concentration in houses were done for these two regions. It was found that there is considerable seasonal variation in the levels of radon in Kerala but the variation in Kuala Lumpur is only less than 10%.

The role of the US Department of Energy in indoor air quality and building ventilation policy development  

SciTech Connect

Building ventilation consumes about 5.8 exajoules of energy each year in the US The annual cost of this energy, used for commercial building fans (1.6 exajoules) and the heating and cooling of outside air (4.2 exajoules), is about $US 33 billion per year. Energy conservation measures that reduce heating and cooling season ventilation rates 15 to 35% in commercial and residential buildings can result in a national savings of about 0.6 to 1.5 exajoules ($US 3-8 billion) per year assuming no reduction of commercial building fan energy use. The most significant adverse environmental impact of reduced ventilation and infiltration is the potential degradation of the buildings indoor air quality. Potential benefits to the US from the implementation of sound indoor air quality and building ventilation reduction policies include reduced building-sector energy consumption; reduced indoor, outdoor, and global air pollution; reduced product costs; reduced worker absenteeism; reduced health care costs; reduced litigation; increased worker well-being and productivity; and increased product quality and competitiveness.

Carbon monoxide in indoor ice skating rinks: Evaluation of absorption by adult hockey players  

Science Conference Proceedings (OSTI)

We evaluated alveolar carbon monoxide (CO) levels of 122 male, adult hockey players active in recreational leagues of the Quebec City region (Canada), before and after 10 weekly 90-minute games in 10 different rinks. We also determined exposure by quantifying the average CO level in the rink during the games. Other variables documented included age, pulmonary function, aerobic capacity, and smoking status. Environmental concentrations varied from 1.6 to 131.5 parts per million (ppm). We examined the absorption/exposure relationship using a simple linear regression model. In low CO exposure levels, physical exercise lowered the alveolar CO concentration. However, we noted that for each 10 ppm of CO in the ambient air, the players had adsorbed enough CO to raise their carboxyhemoglobin (COHb) levels by 1 percent. This relationship was true both for smokers and non-smokers. We suggest that an average environmental concentration of 20 ppm of CO for the duration of a hockey game (90 minutes) should be reference limit not to be exceeded in indoor skating rinks.

It may be labeled sport utility vehicle, SUV, sport-ute, suburban assault vehicle, or a friend of OPEC (Organization for Petroleum Exporting Countries). It has been the subject of comics, the object of high-finance marketing ploys, and the theme of Dateline. Whatever the label or the occasion, this vehicle is in great demand. The popularity of sport utility vehicles (SUVs) has increased dramatically since the late 1970s, and SUVs are currently the fastest growing segment of the motor vehicle industry. Hoping to gain market share due to the popularity of the expanding SUV market, more and more manufacturers are adding SUVs to their vehicle lineup. One purpose of this study is to analyze the world of the SUV to determine why this vehicle has seen such a rapid increase in popularity. Another purpose is to examine the impact of SUVs on energy consumption, emissions, and highway safety.

The U.S. Environmental Protection Agency (EPA) influences the market for plumbing fixtures and fittings by encouraging consumers to purchase products that carry the WaterSense label, which certifies those products as performing at low flow rates compared to unlabeled fixtures and fittings. As consumers decide to purchase water-efficient products, water consumption will decline nationwide. Decreased water consumption should prolong the operating life of water and wastewater treatment facilities.This report describes the method used to calculate national water savings attributable to EPA?s WaterSense program. A Microsoft Excel spreadsheet model, the National Water Savings (NWS) analysis model, accompanies this methodology report. Version 1.0 of the NWS model evaluates indoor residential water consumption. Two additional documents, a Users? Guide to the spreadsheet model and an Impacts Report, accompany the NWS model and this methodology document. Altogether, these four documents represent Phase One of this project. The Users? Guide leads policy makers through the spreadsheet options available for projecting the water savings that result from various policy scenarios. The Impacts Report shows national water savings that will result from differing degrees of market saturation of high-efficiency water-using products.This detailed methodology report describes the NWS analysis model, which examines the effects of WaterSense by tracking the shipments of products that WaterSense has designated as water-efficient. The model estimates market penetration of products that carry the WaterSense label. Market penetration is calculated for both existing and new construction. The NWS model estimates savings based on an accounting analysis of water-using products and of building stock. Estimates of future national water savings will help policy makers further direct the focus of WaterSense and calculate stakeholder impacts from the program.Calculating the total gallons of water the WaterSense program saves nationwide involves integrating two components, or modules, of the NWS model. Module 1 calculates the baseline national water consumption of typical fixtures, fittings, and appliances prior to the program (as described in Section 2.0 of this report). Module 2 develops trends in efficiency for water-using products both in the business-as-usual case and as a result of the program (Section 3.0). The NWS model combines the two modules to calculate total gallons saved by the WaterSense program (Section 4.0). Figure 1 illustrates the modules and the process involved in modeling for the NWS model analysis.The output of the NWS model provides the base case for each end use, as well as a prediction of total residential indoor water consumption during the next two decades. Based on the calculations described in Section 4.0, we can project a timeline of water savings attributable to the WaterSense program. The savings increase each year as the program results in the installation of greater numbers of efficient products, which come to compose more and more of the product stock in households throughout the United States.

Investigating Indoor Radon Levels and Influencing Factors in Primary Schools of Zulfi City, Saudi Arabia  

SciTech Connect

Measurement of indoor Concentrations were performed in Zulfi city of Saudi Arabia, using CR-39 track etch detectors. This investigation focused on the influence of different parameters, namely different locations, school categories, school building types, and room type as well as on the existence of differences in radon concentration at floor levels. We divided the Zulfi city into five regions, keeping in mind their geographical locations between Tuwaiq Mountains and Al-Thuwayrat sands. The measured average radon concentrations for regions 1-5 respectively are: 87.0{+-}14.2 Bq/m{sup 3}, 83.4{+-}6.0 Bq/m{sup 3}, 61.6{+-}6.4 Bq/m{sup 3}, 63.7{+-}5.4 Bq/m{sup 3} and 87.5{+-}6.Bq/m{sup 3} and the minimum concentrations are 28.0 Bq/m{sup 3}, 5.5 Bq/m{sup 3}, 1.1 Bq/m{sup 3}, 1.0 Bq/m{sup 3} and 24 Bq/m{sup 3} respectively. These results are still within normal limits and below the action level of 148 Bqm{sup -3} set by the U.S. Environmental Protection Agency (EPA). A test of significance using Minitab program was applied to investigate if radon levels in regions are significantly different from each other. We tried all combinations, and found the following results. The ''within regions''(different location) test yielded, region 2 is not significant versus region ''1''(p = 0.783) and versus region ''5''(P = 0.646), whereas it is significant versus region ''3''(P = 0.0160) and also versus region ''4''(p = 0.018). We investigated government and rented school's building also and none was found significantly different (p = 0.052). Floors of the same building were tested in order to examine the radon concentration as a function of storey level. No significant difference was observed at floor levels (p = 0.009). When girl's schools versus Boys and kindergartens schools were tested they were found significantly different. It is believed that this significant difference is due to geographical nature of the area, since most of the girl's schools were selected from regions 2 and 3, these regions are relatively close to the Tuwaiq mountains whereas other regions are near to the Al-Thuwayrat sands.

Bayesian based design of real-time sensor systems for high-risk indoor contaminants  

Science Conference Proceedings (OSTI)

The sudden release of toxic contaminants that reach indoor spaces can be hazardousto building occupants. To respond effectively, the contaminant release must be quicklydetected and characterized to determine unobserved parameters, such as release locationand strength. Characterizing the release requires solving an inverse problem. Designinga robust real-time sensor system that solves the inverse problem is challenging becausethe fate and transport of contaminants is complex, sensor information is limited andimperfect, and real-time estimation is computationally constrained.This dissertation uses a system-level approach, based on a Bayes Monte Carloframework, to develop sensor-system design concepts and methods. I describe threeinvestigations that explore complex relationships among sensors, network architecture,interpretation algorithms, and system performance. The investigations use data obtainedfrom tracer gas experiments conducted in a real building. The influence of individual sensor characteristics on the sensor-system performance for binary-type contaminant sensors is analyzed. Performance tradeoffs among sensor accuracy, threshold level and response time are identified; these attributes could not be inferred without a system-level analysis. For example, more accurate but slower sensors are found to outperform less accurate but faster sensors. Secondly, I investigate how the sensor-system performance can be understood in terms of contaminant transport processes and the model representation that is used to solve the inverse problem. The determination of release location and mass are shown to be related to and constrained by transport and mixing time scales. These time scales explain performance differences among different sensor networks. For example, the effect of longer sensor response times is comparably less for releases with longer mixing time scales. The third investigation explores how information fusion from heterogeneous sensors may improve the sensor-system performance and offset the need for more contaminant sensors. Physics- and algorithm-based frameworks are presented for selecting and fusing information from noncontaminant sensors. The frameworks are demonstrated with door-position sensors, which are found to be more useful in natural airflow conditions, but which cannot compensate for poor placement of contaminant sensors. The concepts and empirical findings have the potential to help in the design of sensor systems for more complex building systems. The research has broader relevance to additional environmental monitoring problems, fault detection and diagnostics, and system design.

Measurement and apportionment of radon source terms for modeling indoor environments. Final progress report, March 1990--August 1992  

SciTech Connect

During the present 2 1/2 year contract period, we have made significant Progress in modeling the source apportionment of indoor {sup 222}Rn and in {sup 222}Rn decay product dosimetry. Two additional areas were worked on which we believe are useful for the DOE Radon research Program. One involved an analysis of the research house data, grouping the hourly house {sup 222}Rn measurements into 2 day, 7 day and 90 day intervals to simulate the response of passive monitors. Another area requiring some attention resulted in a publication of 3 years of our indoor/outdoor measurements in a high-rise apartment. Little interest has been evinced in apartment measurements yet 20% of the US population lives in multiple-family dwellings, not in contact with the ground. These data together with a summary of all other published data on apartments showed that apartments have only about 50% greater {sup 222}Rn concentration than the measured outdoor {sup 222}Rn. Apartment dwellers generally represent a low risk group regarding {sup 222}Rn exposure. The following sections describe the main projects in some detail.

Improving Ventilation and Saving Energy: Final Report on Indoor Environmental Quality and Energy Monitoring in Sixteen Relocatable Classrooms  

Science Conference Proceedings (OSTI)

An improved HVAC system for portable classrooms was specified to address key problems in existing units. These included low energy efficiency, poor control of and provision for adequate ventilation, and excessive acoustic noise. Working with industry, a prototype improved heat pump air conditioner was developed to meet the specification. A one-year measurement-intensive field-test of ten of these IHPAC systems was conducted in occupied classrooms in two distinct California climates. These measurements are compared to those made in parallel in side by side portable classrooms equipped with standard 10 SEER heat pump air conditioner equipment. The IHPAC units were found to work as designed, providing predicted annual energy efficiency improvements of about 36 percent to 42 percent across California's climate zones, relative to 10 SEER units. Classroom ventilation was vastly improved as evidenced by far lower indoor minus outdoor CO2 concentrations. TheIHPAC units were found to provide ventilation that meets both California State energy and occupational codes and the ASHRAE minimum ventilation requirements; the classrooms equipped with the 10 SEER equipment universally did not meet these targets. The IHPAC system provided a major improvement in indoor acoustic conditions. HVAC system generated background noise was reduced in fan-only and fan and compressor modes, reducing the nose levels to better than the design objective of 45 dB(A), and acceptable for additional design points by the Collaborative on High Performance Schools. The IHPAC provided superior ventilation, with indoor minus outdoor CO2 concentrations that showed that the Title 24 minimum ventilation requirement of 15 CFM per occupant was nearly always being met. The opposite was found in the classrooms utilizing the 10 SEER system, where the indoor minus outdoor CO2 concentrations frequently exceeded levels that reflect inadequate ventilation. Improved ventilation conditions in the IHPAC lead to effective removal of volatile organic compounds and aldehydes, on average lowering the concentrations by 57 percent relative to the levels in the 10 SEER classrooms. The average IHPAC to 10 SEER formaldehyde ratio was about 67 percent, indicating only a 33 percent reduction of this compound in indoor air. The IHPAC thermal control system provided less variability in occupied classroom temperature than the 10 SEER thermostats. The average room temperatures in all seasons tended to be slightly lower in the IHPAC classrooms, often below the lower limit of the ASHRAE 55 thermal comfort band. State-wide and national energy modeling provided conservative estimates of potential energy savings by use of the IHPAC system that would provide payback a the range of time far lower than the lifetime of the equipment. Assuming electricity costs of $0.15/kWh, the perclassroom range of savings is from about $85 to $195 per year in California, and about $89 to $250 per year in the U.S., depending upon the city. These modelsdid not include the non-energy benefits to the classrooms including better air quality and acoustic conditions that could lead to improved health and learning in school. Market connection efforts that were part of the study give all indication that this has been a very successful project. The successes include the specification of the IHPAC equipment in the CHPS portable classroom standards, the release of a commercial product based on the standards that is now being installed in schools around the U.S., and the fact that a public utility company is currently considering the addition of the technology to its customer incentive program. These successes indicate that the IHPAC may reach its potential to improve ventilation and save energy in classrooms.

Study of the atmospheric chemistry of radon progeny in laboratory and real indoor atmospheres. Progress report, July 1, 1992--March 31, 1993  

Science Conference Proceedings (OSTI)

This report describes studies on the chemical and physical behavior of the {sup 218}Po atom immediately following its formation by the alpha decay of radon. Because small changes in size for activity in the sub-10 nm size range result in large changes in the delivered dose per unit exposure, this behavior must be understood if the exposure to radon progeny and its dose to the cells in the respiratory tract are to be fully assessed. The specific tasks of the controlled laboratory studies are to determine the formation rates of {center_dot}OH radicals formed by the radiolysis of air following radon decay, to examine the formation of particles by the radiolytic oxidation of substances like SO{sub 2} ethylene, and H{sub 2}S to lower vapor pressure compounds and determine the role of gas phase additives such as H{sub 2}O and NH{sub 3} in determining the particle size, to measure the rate of ion-induced nucleation using a thermal diffusion cloud chamber, and to measure the neutralization rate of {sup 218}Po{sub x}{sup +} in O{sub 2} at low radon concentrations. Tasks of the exposure studies in occupied indoor spaces are to initiate measurements of the activity size distributions in actual homes with occupants present so that the variability of the indoor activity size distributions can be assessed with respect to indoor aerosol sources and general lifestyle variations of the occupants, to initiate a prospective study of the utility of measurement of deposited {sup 210}Pb embedded in glass surfaces as a measure of the long-term, integrated exposure of the population to radon, and to develop the methodology to determine the hygroscopicity of the indoor aerosol so that the changes in deposition efficiency of the radioactive indoor aerosol with hygroscopic growth in the respiratory tract can be assessed.

A survey and critical review of the literature on indoor air quality, ventilation and health symptoms in schools  

Science Conference Proceedings (OSTI)

A survey and critical review were undertaken of existing published literature and reports on indoor air quality (IAQ), ventilation, and IAQ- and building-related health problems in schools, including California schools. Over 450 relevant publications were obtained and reviewed, including papers published in the archival peer-reviewed scientific literature, proceedings of scientific meetings, government reports, 77 NIOSH Health Hazard Evaluation Reports (HHER) and 70 reports on investigations of problem schools in California. Most of the reviewed literature was for complaint or problem schools. The types of health symptoms reported in schools were very similar to those defined as sick building syndrome (SBS) symptoms, although this may be due, at least in part, to the type of health symptom questionnaires used. Some of the symptoms, e.g., wheezing, are indicative of asthma. In the studies in which complaint and noncomplaint buildings or areas were compared, complaint buildings generally had higher rates of health symptoms.

Study of the atmospheric chemistry of radon progeny in laboratory and real indoor atmospheres. Progress report, July 1, 1991--June 30, 1992  

Science Conference Proceedings (OSTI)

This report covers the second year of the 28 month grant current grant to Clarkson University to study the chemical and physical behavior of the polonium 218 atom immediately following its formation by the alpha decay of radon. Because small changes in size for activity result in large changes in the delivered dose per unit exposure, this behavior must be understood if the exposure to radon progeny and it dose to the cells in the respiratory tract are to be fully assessed. Two areas of radon progeny behavior are being pursued; laboratory studies under controlled conditions to better understand the fundamental physical and chemical process that affect the progeny`s atmospheric behavior and studies in actual indoor environments to develop a better assessment of the exposure of the occupants of that space to the size and concentration of the indoor radioactive aerosol. This report describes the progress toward achieving these objectives.

Evaluation of Ultra-Violet Photocatalytic Oxidation (UVPCO) forIndoor Air Applications: Conversion of Volatile Organic Compounds at LowPart-per-Billion Concentrations  

SciTech Connect

Efficient removal of indoor generated airborne particles and volatile organic compounds (VOCs) in office buildings and other large buildings may allow for a reduction in outdoor air supply rates with concomitant energy savings while still maintaining acceptable indoor air quality in these buildings. Ultra-Violet Photocatalytic Oxidation (UVPCO) air cleaners have the potential to achieve the necessary reductions in indoor VOC concentrations at relatively low cost. In this study, laboratory experiments were conducted with a scaled, prototype UVPCO device designed for use in a duct system. The experimental UVPCO contained two 30 by 30-cm honeycomb monoliths coated with titanium dioxide and 3% by weight tungsten oxide. The monoliths were irradiated with 12 UVC lamps arranged in four banks. The UVPCO was challenged with four mixtures of VOCs typical of mixtures encountered in indoor air. A synthetic office mixture contained 27 VOCs commonly measured in office buildings. A cleaning product mixture contained three cleaning products with high market shares. A building product mixture was created by combining sources including painted wallboard, composite wood products, carpet systems, and vinyl flooring. A fourth mixture contained formaldehyde and acetaldehyde. Steady-state concentrations were produced in a classroom laboratory or a 20-m{sup 3} environmental chamber. Air was drawn through the UVPCO, and single pass conversion efficiencies were measured from replicate air samples collected upstream and downstream of the reactor section. Concentrations of the mixtures were manipulated, with concentrations of individual VOCs mostly maintained below 10 ppb. Device flow rates were varied between 165 and 580 m{sup 3}/h. Production of formaldehyde, acetaldehyde, acetone, formic acid, and acetic acid as reaction products was investigated. Conversion efficiency data were generated for 48 individual VOCs or groups of closely related compounds. Alcohols and glycol ethers were the most reactive chemical classes with conversion efficiencies often near or above 70% at the low flow rate and near 40% at the high flow rate. Ketones and terpene hydrocarbons were somewhat less reactive. The relative VOC conversion rates are generally favorable for treatment of indoor air since many contemporary products used in buildings employ oxygenated solvents. A commercial UVPCO device likely would be installed in the supply air stream of a building and operated to treat both outdoor and recirculated air. Assuming a recirculation rate comparable to three times the normal outdoor air supply rate, simple mass-balance modeling suggests that a device with similar characteristics to the study unit has sufficient conversion efficiencies for most VOCs to compensate for a 50% reduction in outdoor air supply without substantially impacting indoor VOC concentrations. Formaldehyde, acetaldehyde, acetone, formic acid, and acetic acid were produced in these experiments as reaction byproducts. No other significant byproducts were observed. A coupled steady-state mass balance model is presented and applied to VOC data from a study of a single office building. For the operating assumptions described above, the model estimated a three-fold increase in indoor formaldehyde and acetaldehyde concentrations. The outcome of this limited assessment suggests that evaluation of the potential effects of the operation of a UVPCO device on indoor concentrations of these contaminants is warranted. Other suggested studies include determining VOC conversion efficiencies in actual buildings and evaluating changes in VOC conversion efficiency as monoliths age with long-term operation.

Investigating Servant Leadership in the Context of Cause-Related Sporting Events  

E-Print Network (OSTI)

This dissertation presents three separate studies designed to provide systematic and evidence-based insight into how servant leadership could be a crucial success factor in helping non-profit organizations (NPOs) hosting cause-related sporting events achieve their missions. Thus, the purpose of my dissertation was to advance the literature and the practice of servant leadership. In Study one, I conducted a systematic literature review of studies that explored an application of servant leadership. A disciplined screening process resulted in a sample population of 39 studies. The synthesis of these applied studies revealed: a) there is no consensus on the definition of servant leadership; b) servant leadership is being applied across a variety of contexts, cultures, and themes; c) researchers are using multiple measures to explore servant leadership; and d) these studies provide strong evidence that servant leadership helps organizations and improves the well-being of followers. In Study two, I explored the leadership style of the founder of a cause-related sporting event to understand how this leadership style motivated volunteers. This was achieved through semi-structured personal interviews, document analysis, and personal observations of the 25th National Kidney Foundation (NKF) Surf Festival. Results indicated that the founder was a servant leader who influenced volunteer motivation by generating a shared vision dedicated to helping others, building a caring and loving community, and creating the freedom and resources for followers to become servants themselves. In Study three, using a longitudinal case study, I qualitatively explored if a cause-related sporting event could inspire participants to become servant leaders, and if so, how does the event achieve this? Data collection methods included focus groups, open-ended qualitative questionnaires, direct observations, document analysis, and semi-structured personal interviews with participants of the U.S. NKF Transplant Games, specifically Team Florida. Analyses revealed the event inspired participants to serve others and helped to build a community of servant leaders. It was found that three specific mechanisms of the Games generated community-level outcomes, which led to impacts on participants and helped them develop servant leadership. I then developed a model to describe a cause-related sporting event's ability to inspire participants to become servant leaders.

Relationships between {sup 222}Rn dissolved in ground water supplies and indoor {sup 222}Rn concentrations in some Colorado front range houses  

SciTech Connect

Indoor {sup 222}Rn concentrations were measured in 37 houses with alpha track detectors placed in water-use rooms near water sources (bathrooms, laundry rooms, and kitchens) and in non-water-use living rooms, dining rooms, and bedrooms away from water sources. Results show that relative contributions of {sup 222}Rn to indoor air from water use are insignificant when soil-gas concentrations are high but become increasingly important as the ratio of {sup 222}Rn-in-water:{sup 222}Rn-in-soil gas increases. High soil-gas {sup 222}Rn concentrations may mask {sup 222}Rn contributions from water even when waterborne {sup 222}Rn concentrations are as high as 750 kBq m{sup {minus}3}. Ground water in Precambrian Pikes Peak granite averages 340 kBq m{sup {minus}3} {sup 222}Rn, vs. 170 kBq m{sup {minus}3} in Precambrian migmatite, but average {sup 222}Rn concentrations in soil gas are also lower in migmatite. Because the ratio of {sup 222}Rn-in-water:{sup 222}Rn-in-soil gas may be consistently higher for houses in migmatite than in Pikes Peak granite, indoor air in houses built on migmatite have a greater relative contribution from water use even though average {sup 222}Rn concentrations in the water are lower. Continuous monitoring of {sup 222}Rn concentrations in air on 15-min intervals also indicates that additions to indoor concentrations from water use are significant and measurable only when soil-gas concentrations are low and concentrations in water are high. When soil-gas concentrations were mitigated to less than 150 Bq m{sup {minus}3} in one house, water contributed 20-40% of the annual indoor {sup 222}Rn concentration in the laundry room ({sup 222}Rn concentration in water of 670 kBq m{sup {minus}3}). Conversely, when the mitigation system is inactive, diurnal fluctuations and other variations in the soil-gas {sup 222}Rn contribution swamp the variability due to water use in the house. 9 refs., 8 figs., 8 tabs.

Mass transfer of volatile organic compounds from drinking water to indoor air: The role of residential dishwashers  

Science Conference Proceedings (OSTI)

Contaminated tap water may be a source of volatile organic compounds (VOCs) in residential indoor air. To better understand the extent and impact of chemical emissions from this source, a two-phase mass balance model was developed based on mass transfer kinetics between each phase. Twenty-nine experiments were completed using a residential dishwasher to determine model parameters. During each experiment, inflow water was spiked with a cocktail of chemical tracers with a wide range of physicochemical properties. In each case, the effects of water temperature, detergent, and dish-loading pattern on chemical stripping efficiencies and mass transfer coefficients were determined. Dishwasher headspace ventilation rates were also measured using an isobutylene tracer gas. Chemical stripping efficiencies for a single cycle ranged from 18% to 55% for acetone, from 96% to 98% for toluene, and from 97% to 98% for ethylbenzene and were consistently 100% for cyclohexane. Experimental results indicate that dishwashers have a relatively low but continuous ventilation rate that results in significant chemical storage within the headspace of the dishwasher. In conjunction with relatively high mass transfer coefficients, low ventilation rates generally lead to emissions that are limited by equilibrium conditions after approximately 1--2 min of dishwasher operation.

Parametric Evaluation of an Innovative Ultra-Violet PhotocatalyticOxidation (UVPCO) Air Cleaning Technology for Indoor Applications  

SciTech Connect

An innovative Ultra-Violet Photocatalytic Oxidation (UVPCO) air cleaning technology employing a semitransparent catalyst coated on a semitransparent polymer substrate was evaluated to determine its effectiveness for treating mixtures of volatile organic compounds (VOCs) representative of indoor environments at low, indoor-relevant concentration levels. The experimental UVPCO contained four 30 by 30-cm honeycomb monoliths irradiated with nine UVA lamps arranged in three banks. A parametric evaluation of the effects of monolith thickness, air flow rate through the device, UV power, and reactant concentrations in inlet air was conducted for the purpose of suggesting design improvements. The UVPCO was challenged with three mixtures of VOCs. A synthetic office mixture contained 27 VOCs commonly measured in office buildings. A building product mixture was created by combining sources including painted wallboard, composite wood products, carpet systems, and vinyl flooring. The third mixture contained formaldehyde and acetaldehyde. Steady state concentrations were produced in a classroom laboratory or a 20-m{sup 3} chamber. Air was drawn through the UVPCO, and single-pass conversion efficiencies were measured from replicate samples collected upstream and downstream of the reactor. Thirteen experiments were conducted in total. In this UVPCO employing a semitransparent monolith design, an increase in monolith thickness is expected to result in general increases in both reaction efficiencies and absolute reaction rates for VOCs oxidized by photocatalysis. The thickness of individual monolith panels was varied between 1.2 and 5 cm (5 to 20 cm total thickness) in experiments with the office mixture. VOC reaction efficiencies and rates increased with monolith thickness. However, the analysis of the relationship was confounded by high reaction efficiencies in all configurations for a number of compounds. These reaction efficiencies approached or exceeded 90% for alcohols, glycol ethers, and other individual compounds including d-limonene, 1,2,4-trimethylbenzene, and decamethylcyclopentasiloxane. This result implies a reaction efficiency of about 30% per irradiated monolith face, which is in agreement with the maximum efficiency for the system predicted with a simulation model. In these and other experiments, the performance of the system for highly reactive VOCs appeared to be limited by mass transport of reactants to the catalyst surface rather than by photocatalytic activity. Increasing the air flow rate through the UVPCO device decreases the residence time of the air in the monoliths and improves mass transfer to the catalyst surface. The effect of gas velocity was examined in four pairs of experiments in which the air flow rate was varied from approximately 175 m{sup 3}/h to either 300 or 600 m{sup 3}/h. Increased gas velocity caused a decrease in reaction efficiency for nearly all reactive VOCs. For all of the more reactive VOCs, the decrease in performance was less, and often substantially less, than predicted based solely on residence time, again likely due to mass transfer limitations at the low flow rate. The results demonstrate that the UVPCO is capable of achieving high conversion efficiencies for reactive VOCs at air flow rates above the base experimental rate of 175 m{sup 3}/h. The effect of UV power was examined in a series of experiments with the building product mixture in which the number of lamps was varied between nine and three. For the most reactive VOCs in the mixture, the effects of UV power were surprisingly small. Thus, even with only one lamp in each section, there appears to be sufficient photocatalytic activity to decompose most of the mass of reactive VOCs that reach the catalyst surface. For some less reactive VOCs, the trend of decreasing efficiency with decreasing UV intensity was in general agreement with simulation model predictions.

Optimization Measures for Sporting and Special Event Facilities: Design and Operation  

E-Print Network (OSTI)

Reducing unnecessary building energy costs is becoming more of a priority. Rising fuel prices and a global emphasis on energy efficiency are key contributing factors. This push towards energy efficiency certainly applies to today's athletic and special event facilities. High customer expectations and corresponding large operating expenses have helped to make energy conservation measures more of a priority in the facilities design. The heating, ventilation, and air conditioning (HVAC) systems in sporting and special event facility present a unique challenge to Continuous Commissioning (CC) engineers. In such facilities, high occupancy and equipment loads occur at the design load condition, but only a small fraction of the designed capacity is necessary for routine operations. On the other hand, during games and other events, system performance is critical. Therefore, significant savings potential exists, but care must be taken to avoid compromising the peak load operations. Maintenance uncertainties, equipment wear, and lack of operator knowledge all combine to affect the building operating costs. Continuous Commissioning, a process developed by the Texas A&M Energy Systems Laboratory, addresses issues such as these and proves very worthwhile. An overview of multi-purpose arenas and their usage will be given, and potential optimization measures and Continuous Commissioning of these facilities will be presented, along with some illustrative examples.

Statistical Analysis and Interpretation of Building Characterization, Indoor Environmental Quality Monitoring and Energy Usage Data from Office Buildings and Classrooms in the United States  

Science Conference Proceedings (OSTI)

Three independent tasks had been performed (Stetzenbach 2008, Stetzenbach 2008b, Stetzenbach 2009) to measure a variety of parameters in normative buildings across the United States. For each of these tasks 10 buildings were selected as normative indoor environments. Task 1 focused on office buildings, Task 13 focused on public schools, and Task 0606 focused on high performance buildings. To perform this task it was necessary to restructure the database for the Indoor Environmental Quality (IEQ) data and the Sound measurement as several issues were identified and resolved prior to and during the transfer of these data sets into SPSS. During overview discussions with the statistician utilized in this task it was determined that because the selection of indoor zones (1-6) was independently selected within each task; zones were not related by location across tasks. Therefore, no comparison would be valid across zones for the 30 buildings so the by location (zone) data were limited to three analysis sets of the buildings within each task. In addition, differences in collection procedures for lighting were used in Task 0606 as compared to Tasks 01 & 13 to improve sample collection. Therefore, these data sets could not be merged and compared so effects by-day data were run separately for Task 0606 and only Task 01 & 13 data were merged. Results of the statistical analysis of the IEQ parameters show statistically significant differences were found among days and zones for all tasks, although no differences were found by-day for Draft Rate data from Task 0606 (p>0.05). Thursday measurements of IEQ parameters were significantly different from Tuesday, and most Wednesday measures for all variables of Tasks 1 & 13. Data for all three days appeared to vary for Operative Temperature, whereas only Tuesday and Thursday differed for Draft Rate 1m. Although no Draft Rate measures within Task 0606 were found to significantly differ by-day, Temperature measurements for Tuesday and Thursday showed variation. Moreover, Wednesday measurements of Relative Humidity within Task 0606 varied significantly from either Tuesday or Thursday. The majority of differences in IEQ measurements by-zone were highly significant (pschool buildings S02, S04, and S05, respectively.

AN ANALYSIS OF THE IMPACT OF SPORTS UTILITY VEHICLES IN THE UNITED STATES  

Science Conference Proceedings (OSTI)

During the 1990s, sport utility vehicles (SUVs) became the fastest growing segment of the auto industry, especially those in the medium-size category. In 1999, SUV sales reached almost 19% of the total light vehicle market and the mix of SUVs on the road, as measured by registration data, was about 8.7%. This immense popularity has been called by some a passing fad--vehicle purchases based on the SUV ''image''. But the continued yearly increases in SUV sales seem to indicate a more permanent trend. Additional explanations for SUV popularity include the general economic well being in the United States, a perception of safety, and ''utility''. Generally larger and heavier than the typical automobile, SUVs require more fuel per mile to operate and produce greater amounts of pollutants. They are also driven further annually than are automobiles of the same vintage, a fact that exacerbates the fuel-use and emission problems. Although buyers believe that SUVs are safer than automobiles which they are in some cases, SUVs are more prone to roll-overs than are automobiles. In addition, SUVs, with their higher bumpers and greater weight, may be a threat to other vehicles on the highway, especially in side-impact crashes. With sales projected to grow to over 3 million units per year beginning in 2001, SUVs show no sign of decreasing in popularity. These vehicles are used primarily for general mobility, rather than off-road activities. An emphasis on better fuel economy and improved emissions control could address environmental and oil dependency concerns. In fact, recently, two vehicle manufacturers announced intentions of improving the fuel economy of their SUVs in the next few years. Also, tests simulating crashes involving automobiles and SUVs could provide valuable data for identifying potential safety design issues. It is clear that automobiles and SUVs will be sharing the highways for years to come.

Thursday measurements of IEQ parameters were significantly different from Tuesday, and most Wednesday measures for all variables of Tasks 1 & 13. Data for all three days appeared to vary for Operative Temperature, whereas only Tuesday and Thursday differed for Draft Rate 1m. Although no Draft Rate measures within Task 0606 were found to significantly differ by-day, Temperature measurements for Tuesday and Thursday showed variation. Moreover, Wednesday measurements of Relative Humidity within Task 0606 varied significantly from either Tuesday or Thursday. The majority of differences in IEQ measurements by-zone were highly significant (p<0.001), with the exception of Relative Humidity in some buildings. When all task data were combined (30 buildings) neither the airborne culturable fungi nor the airborne non-culturable spore data differed in the concentrations found at any indoor location in terms of day of collection. However, the concentrations of surface-associated fungi varied among the day of collection. Specifically, there was a lower concentration of mold on Tuesday than on Wednesday, for all tasks combined. As expected, variation was found in the concentrations of both airborne culturable fungi and airborne non-culturable fungal spores between indoor zones (1-6) and the outdoor zone (zone 0). No variation was found among the indoor zones of office buildings for Task 1 in the concentrations of airborne culturable fungi. However, airborne non-culturable spores did vary among zones in one building in Task 1 and variation was noted between zones in surface-associated fungi. Due to the lack of multiple lighting measurements for Tasks 13 and 0606, by-day comparisons were only performed for Task 1. No statistical differences were observed in lighting with respect to the day of collection. There was a wide range of variability by-zone among seven of the office buildings. Although few differences were found for the brightest illumination of the worksurface (IllumWkSfcBrtst) and the darkest illumination of the worksurface (IllumWkSfcDrkst) in Task 1, there was considerable variation for these variables in Task 13 and Task 0606 (p < 0.001). Other variables that differed by-zone in Task 13 include CombCCT and AmbCCT1 for S03, S07, and S08. Additionally, AmbChromX1, CombChromY, and CombChromX varied by-zone for school buildings S02, S04, and S05, respectively.

Participatory Pricing in Sport: An Examination of Name-Your-Own-Price and Pay-What-You-Want Pricing  

E-Print Network (OSTI)

The purpose of this study is to better understand the effects participatory pricing strategies have on consumer perceptions and behaviors in a sport event pricing scenario. Participatory pricing strategies are those that include the consumer in setting the final price of a good or service. These mechanisms include name-your-own-price (NYOP) and pay-what-you-want (PWYW). These pricing strategies are now being introduced into the sport industry. With the increased use of these strategies, and the lack of research in sport management pertaining to consumers’ perceptions of price, specifically consumer voice in price setting, there is a gap in the literature that needs to be filled. This study investigates the consumer’s perceptions of price fairness, perceived value, as well as consumer behavior (i.e. purchase intentions and willingness-to-pay), when encountering participatory pricing strategies. The following dissertation presents a quantitative experimental design, asking subjects to participate in a simulated ticket purchase experience. Difference between experimental groups was assessed based on price fairness, perceived value, willingness-to-pay, and purchase intentions. Results indicate there is a significant difference between participatory pricing groups and traditional fixed price groups when examining price fairness, perceived value, willingness-to-pay, and final average prices paid. Specifically, price fairness evaluations were significantly higher for the PWYW and fixed price groups, and lower for the NYOP group. In addition to the price fairness differences, the groups differed on their evaluations of perceived value (PWYW and fixed are the same, both higher than NYOP). Furthermore, the results reveal that consumers involved in the NYOP mechanism evoked higher levels of willingness-to-pay than PWYW and fixed. Furthermore, the study also found that the final average price paid following the experiment differed based on the mechanism. The PWYW and fixed price mechanisms paid similar amounts, while both of them were significantly higher than the NYOP mechanism. This suggests that while one of the biggest concerns for the PWYW treatment is a low final average price (even $0); this may not be an issue in a sport ticket pricing scenario. Study limitations and future research are included in the following dissertation.

Interest group lifecycles and recreational fishing: an exploratory study in the evolution of two sport fishing groups  

E-Print Network (OSTI)

This research is a comparative, exploratory case study of the evolution of the Sport Fishing Institute and the Coastal Conservation Association. The study details the life histories of these two recreational fishing interest groups in order that it may be seen how interest groups change and why they do so. Initial propositions suggest there are three developmental stages in the lifecycle of an interest group. Additionally, there are eight variables of change that are characteristic of each stage. These variables may be used to classify the interest group according to its developmental stage. Finally, it is suggested that these changes are part of a general and predictable pattern in the interest group's lifecycle. Data for the study was obtained over a two year period through document search and extensive interviews with key informants, both inside and outside the organizations. Findings of the study indicate that there are three stages of development in these interest group's lifecycles. The stages are; nascent, developing, and mature. Data indicates that the Sport Fishing Institute has evolved to the mature stage, while the Coastal Conservation Association is in the developing stage. Characteristics of each stage are defined, as are the circumstances necessary for movement from one stage to another and the common problems faced by most interest groups.

Pollutant dispersion in a large indoor space: Part 2 -Computational Fluid Dynamics (CFD) predictions and comparison with ascale model experiment for isothermal flow  

SciTech Connect

This paper reports on an investigation of the adequacy of Computational fluid dynamics (CFD), using a standard Reynolds Averaged Navier Stokes (RANS) model, for predicting dispersion of neutrally buoyant gas in a large indoor space. We used CFD to predict pollutant (dye) concentration profiles in a water filled scale model of an atrium with a continuous pollutant source. Predictions from the RANS formulation are comparable to an ensemble average of independent identical experiments. Model results were compared to pollutant concentration data in a horizontal plane from experiments in a scale model atrium. Predictions were made for steady-state (fully developed) and transient (developing) pollutant concentrations. Agreement between CFD predictions and ensemble averaged experimental measurements is quantified using the ratios of CFD-predicted and experimentally measured dye concentration at a large number of points in the measurement plane. Agreement is considered good if these ratios fall between 0.5 and 2.0 at all points in the plane. The standard k-epsilon two equation turbulence model obtains this level of agreement and predicts pollutant arrival time to the measurement plane within a few seconds. These results suggest that this modeling approach is adequate for predicting isothermal pollutant transport in a large room with simple geometry.

System for reducing heat losses from indoor swimming pools by use of automatic covers. Final report, October 1, 1993--September 30, 1995  

SciTech Connect

This final report is an account of the principal activities of Lof Energy Systems, Inc. in a two-year project funded by the Energy Related Inventions Program (ERIP) of the U.S. Department of Energy. The primary objective has been the development of a fully practical and economical system for saving energy in indoor swimming pools by use of motorized covers. The goal is wide-spread use of a fully developed product, in institutional swimming pools. Four major tasks, depicted in the accompanying Performance Schedule, have been completed, and one other has been initiated and its completion committed. Principal accomplishments have been the selection and improvement of cover materials and designs, lengthening and strengthening of reels and improvements in motorized components and their control, design and installation of pool covers in full scale demonstration and evaluation of fully developed commercial system, preparation and dissemination of manuals and reports, finalization of arrangements for Underwriters Laboratory certification of products, and final report preparation and submission. Of greatest significance has been the successful demonstration of the fully developed system and the verification and reporting by an energy consultant of the large savings resulting from pool cover use. Probably the best evidence of success of the DOE-ERIP project in advancing this invention to a commercial stage is its acceptance for sale by the Lincoln Equipment Company, a national distributor of swimming pool supplies and equipment. A copy of the relevant page in the Lincoln catalog is included in this report as Annex A. Representatives of that company now offer Tof motorized pool cover systems to their pool owner customers. In addition to the plans for securing UL certification the company expects to continue making design improvements that can increase system reliability, durability, and cost-effectiveness.

Development of Technologies for a High Efficiency, Very Low Emission, Diesel Engine for Light Trucks and Sport Utility Vehicles  

DOE Green Energy (OSTI)

Cummins Inc., in partnership with the Department of Energy, has developed technology for a new highly efficient, very low emission, diesel engine for light trucks and sport utility vehicles. This work began in April 1997, and started with very aggressive goals for vehicles in the 5751 to 8500 pound GCW weight class. The primary program goals were as follows: (1) EMISSIONS -- NOx = 0.50 g/mi; PM = 0.05 g/mi; CO = 2.8 g/mi; and NMHC = 0.07 g/mi. California decided to issue new and even tougher LEV II light truck regulations late in 1999. EPA also issued its lower Tier 2 regulations late in 2000. The net result was that the targets for this diesel engine project were lowered, and these goals were eventually modified by the publication of Federal Tier 2 emission standards early in 2000 to the following: NOx = 0.07 g/mi; and PM = 0.01 g/mi. (2) FUEL ECONOMY -- The fuel economy goal was 50 percent MPG improvement (combined city/highway) over the 1997 gasoline powered light truck or sport utility vehicle in the vehicle class for which this diesel engine is being designed to replace. The goal for fuel economy remained at 50 percent MPG improvement, even with the emissions goal revisions. (3) COOPERATIVE DEVELOPMENT -- Regular design reviews of the engine program will be conducted with a vehicle manufacturer to insure that the concepts and design specifics are commercially feasible. (DaimlerChrysler has provided Cummins with this design review input.) Cummins has essentially completed a demonstration of proof-of-principle for a diesel engine platform using advanced combustion and fuel system technologies. Cummins reported very early progress in this project, evidence that new diesel engine technology had been developed that demonstrated the feasibility of the above emissions goals. Emissions levels of NOx = 0.4 g/mi and PM = 0.06 g/mi were demonstrated for a 5250 lb. test weight vehicle with passive aftertreatment only. These results were achieved using the full chassis dynamometer FTP-75 test procedure that allowed compliance with the Tier 2 Interim Bin 10 Standards and would apply to vehicles in MY2004 through MY2007 timeframe. In further technology development with active aftertreatment management, Cummins has been able to report that the emissions goals for the Tier 2 Bin 5 standards were met on an engine running the full FTP-75 test procedure. The fuel economy on the chassis tests was measured at over 59 percent MPG improvement over the gasoline engines that are offered in typical SUVs and light trucks. The above demonstration used only in-cylinder fueling for management of the aftertreatment system.

Evaluation of Common Angling-Induced Sources of Epithelial Damage for Popular Freshwater Sport Fish using Fluorescein  

Science Conference Proceedings (OSTI)

Angling is a popular recreational activity across the globe and a large proportion of fish captured by anglers are released due to voluntary or mandatory catch-and-release practices. The handling associated with hook removal and return of the fish to their environment can cause physical damage to the epidermal layer of the fish which may affect the condition and survival of released fish. This study investigated possible sources of epithelial damage associated with several different handling methods (i.e. landing net types, interactions with different boat floor surfaces, tournament procedures) commonly used in recreational angling for two popular freshwater sport fish species, largemouth bass (Micropterus salmoides) and northern pike (Esox lucius). Epithelial damage was examined using fluorescein, a non-toxic dye, which has been shown to detect latent epithelial damage. Northern pike exhibited extensive epithelial damage after exposure to several of the induced treatments (i.e., interaction with a carpeted surface, knotted nylon net, and line rolling) but relatively little epithelial damage when exposed to others (i.e., knotless rubber nets, smooth boat surfaces, or lip gripping devices). Largemouth bass did not show significant epithelial damage for any of the treatments, with the exception of fish caught in a semi-professional live release tournament. The detection of latent injuries using fluorescein can be an important management tool as it provides visual examples of potential damage that can be caused by different handling methods. Such visualizations can be used to encourage fish friendly angler behaviour and enhance the survival and welfare of released fish. It can also be used to test new products that are intended to or claim to reduce injury to fish that are to be released. Future research should evaluate the relationship between different levels of epithelial damage and mortality across a range of environmental conditions.

The Impact a Diversity Culture Has on the "Think Manager, Think Male" Stereotype: A Social Identity Theory of Leadership Perspective on Gender Stereotypes in Sport Organizations  

E-Print Network (OSTI)

Women in intercollegiate athletics have faced numerous challenges in breaking through the "glass ceiling." This issue has received a plethora of attention in the literature; however, the impact of culture on leadership stereotypes has yet to be evaluated. Therefore, the purpose of this study was to determine the impact a diversity culture may or may not have on gendered leadership stereotypes. Utilizing the social identity theory of leadership and the expectations of gender stereotypes, I predicted men would be considered more prototypical of a sport organization than would women. Moving forward, I argued culture would moderate this relationship. Specifically, women would be considered more prototypical in a proactive culture (diversity viewed as an asset), whereas men would be perceived as more prototypical in compliant cultures (diversity viewed as a liability). Finally, when a leader was determined as prototypical, then (s)he would be rated as more effective than nonprototypical leaders. A 2 (culture: compliant, proactive) by 2 (leader's sex: male, female) design was employed to determine the relationship between culture, sex and leadership prototypicality. Respondents to this research experiment included students participating in activity classes at a major Southwest University (N = 278). Respondents were first asked to read through two scenarios: one describing culture and the other manipulating the leader. Next, they were asked to complete a series of items to measure prototypicality and leadership effectiveness. Results indicated the manipulation in the scenarios was successful. A majority of the respondents correctly identified the leader?s sex (N = 241), and a proactive culture was viewed as supporting diversity when compared to a compliant culture (F [1, 274] = 120.83, p .05, n2 =.001), and culture did not affect prototypicality ratings (b = -.04, p greater than .05). However, culture did have a significant positive relationship with leadership effectiveness (b = 21, p less than .01). Prototypicality was significantly positively related to leadership effectiveness (b = .54, p less than .001), thus supporting the third hypothesis.

Procedure to Measure Indoor Lighting Energy Performance  

SciTech Connect

This document provides standard definitions of performance metrics and methods to determine them for the energy performance of building interior lighting systems. It can be used for existing buildings and for proposed buildings. The primary users for whom these documents are intended are building energy analysts and technicians who design, install, and operate data acquisition systems, and who analyze and report building energy performance data. Typical results from the use of this procedure are the monthly and annual energy used for lighting, energy savings from occupancy or daylighting controls, and the percent of the total building energy use that is used by the lighting system. The document is not specifically intended for retrofit applications. However, it does complement Measurement and Verification protocols that do not provide detailed performance metrics or measurement procedures.

Indoor test for thermal performance of the Sunmaster evacuated tube (liquid) solar collector  

DOE Green Energy (OSTI)

The test procedure used and the results obtained from an evaluation test program conducted to obtain thermal performance data on Sunmaster DEC-8 and 8A (modified) solar collector under simulated conditions are described. These tests were made using the Marshall Space Flight Center's solar simulator. A time constant test and incident angle modifier test were also conducted to determine the transient effect and the incident angle effect on the collector. The Sunmaster evacuated tube solar collector is a water working fluid type. The gross collector area is about 17.17 ft/sup 2/ and weight is approximately 65 pounds empty and 90 pounds filled. The overall dimensions are about 48'' x 51.5'' x 7.8''.

Performance data is provided for current Sunpak production collectors. The effects of an improved manifold are seen from the test results. The test results show excellent correlation between the solar simulator derived test results and outdoor test results. Also, because of different incident angle modifiers, the all-day efficiency of this collector with a diffuse reflector is found to be comparable to the performance with the standard shaped specular reflector.

Robotic security guards will autonomously survey such environments, unless a remote human operator takes over control.

Impacts of Static Pressure Set Level on the HVAC Energy Consumption and Indoor Conditions  

E-Print Network (OSTI)

Air static pressure must be maintained at a certain level leaving the air-handing unit (AHU) to force a suitable amount of air through the terminal boxes. However, an excessive static pressure level is often used due to ( 1 ) lack of a control device in a constant volume system (CV); (2) malfunctioning control device in a variable volume (VAV) system; and (3) fear of failure to maintain room temperature. High static pressure often develops excessive damper leakage in older mixing boxes. This results in an inappropriate mixing of hot and cold air and an excessive amount of air entering the space. Consequently, the actual fan power, heating and cooling energy consumption all become significantly higher than the design values. Even worse, the system may not be able to maintain room conditions due to unwanted simultaneous heating and cooling, and may be noisy due to the excessive static pressure. This paper proposes to control the hot duct pressure and the Variable Frequency Drives ( VFD's) to control the fan static i.e. the cold duct pressure.

Indoor test for thermal performance evaluation of the Northrup Concentrating Solar Collector  

DOE Green Energy (OSTI)

The test procedure used and the results obtained from an evaluation test program conducted to obtain thermal performance data on a Northrup concentrating solar collector under simulated conditions are described. These tests were made using the Marshall Space Flight Center's solar simulator. A time constant test and incident angle modifier test were also conducted to determine the transient effect and the incident angle effect on the collector. The Northrup concentrating solar collector is a water/glycol/working fluid type, dipped galvanized steel housing, transparent acrylic Fresnel lens cover, copper absorber tube, fiber glass insulation and weighs approximately 98 pounds. The gross collector area is about 29.4 ft/sup 2/ per collector. A collector assembly includes four collector units within a tracking mount array.

Stabilization of High Efficiency CdTe Photovoltaic Modules in Controlled Indoor Light Soaking  

Science Conference Proceedings (OSTI)

The performance and stabilization of large-area, high-efficiency 9%, CdTe photovoltaic (PV) modules maintained under controlled light-soaking nominally at 800 Watts/m2 irradiance and 65C module temperature are investigated. Degradation of module performance occurs predominantly in the first few hundred hours of exposure under these conditions; these symptoms included losses in fill factor (FF), open-circuit voltage (Voc), and short-circuit current (Isc), which amount to between 7% and 15% total loss in performance. Higher stabilized performance was achieved with lower copper content in the back contact. Transient effects in module Voc and Isc were observed, suggesting partial annealing thereof when stored under low-light levels. Performance changes are analyzed, aided by monitoring the current-voltage characteristics in situ during exposure.

A survey of carbon monoxide and nitrogen dioxide in indoor ice arenas in Vermont  

Science Conference Proceedings (OSTI)

Because of the history of health problems traceable to the exhaust of ice resurfacing machines, state sanitarians used detector tubes to measure carbon monoxide (CO) and nitrogen dioxide (NO[sub 2]) levels in enclosed ice arenas in Vermont during high school hockey games. Five of eight arenas had average game CO measurements of 30 ppm carbon monoxide or more. Two of the three periods of play had average CO readings in excess of 100 ppm in one arena. Only six arenas had the complete series of nitrogen dioxide measurements. One had an average game NO[sub 2] level of 1.2 ppm. Two had one or more periods of play that averaged in excess of 0.5 ppm. Despite the ample documentation of the hazards of operating combustion-powered resurfacing machines inside enclosed ice arenas, a significant portion of the arenas had undesirable levels of carbon monoxide or nitrogen dioxide. Ice arenas should be routinely monitored for air contaminants. Considerations should be given to the purchase of electric ice resurfacing machines for new arenas and arenas that have air contamination that cannot be resolved with ventilation.
