Book excerpt: Building materials and domestic furnishing are significant sources of VOCs in indoor environments. The range of VOCs is wide. They have a particularly strong impact on indoor air quality during the first two years of a new building. The pollution load in internal atomospheres can be reduced by careful selection of low emission materials. An emission database is being developed at BRE and together with databases in other European countries, will provide building designers and building product users with data to evaluate the impact of selected materials on indoor air quality. Part 1 of this Digest briefly describes sources and methods for measuring VOC emissions, and data for assessing health risks and pollution loads. Part 2 describes available guidelines and labelling schemes for control of VOC emissions in buildings.

This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volatile Organic Compounds (VOC) emitted from building materials have been recognized as major problems affecting human comfort, health and productivity. Building materials not only are main VOC sources but also are main VOC sinks in buildings. Therefore, accurate modeling of building material VOC emissions and sinks is important for predicting contaminant concentrations, occupant exposures and design of mechanical ventilation systems. This thesis describes three new modeling approaches to predict building material VOC emissions and sinks. First, a numerical and an analytical VOC emission model have been developed to predict VOC emission rates of a single-layer dry building material and VOC concentrations in a well-mixed room. Second, an integrated IAQ model has been developed to predict VOC emission rates of a multi-layer material, VOC sink rates of a material, VOC concentrations in a well mixed room with both VOC source and sink materials. Third, a zonal model has been integrated with air jet and material VOC emission/sink models to predict the transient VOC distribution in a ventilated room. In addition, a systematic parametric study has been carried out to study the impacts of model input parameters and their interactions on VOC emissions from building materials. These three models have been validated with available experimental results and/or CFD simulation results. The comparisons with the experimental results and the predictions of the CFD models indicate that there are generally good agreements between the proposed model predictions, the experimental results and the CFD results. Moreover, these three models have been applied to analyze building material VOC emission/sink behaviors and to examine ventilation system efficiency. Results show that the developed models can provide useful information for building owners or designers in selecting proper building materials, designing efficient ventilation systems and assessing indoor air quality.

Book Synopsis Harmonised VOC Emission Classes for Construction Products by : Reihlen Antonia
Download or read book Harmonised VOC Emission Classes for Construction Products written by Reihlen Antonia and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The current documentation summarises the presentations and discussions of an international online conference organised by the German Environment Agency in April 2021 on emission classes for volatile organic compounds (VOCs) in construction products. Construction products are an important source of VOC emissions into indoor air. A chamber test was standardised under the Construction Products Regulation to enable harmonised measurement results of VOC emissions from construction products. If required by the product standards, the VOC emissions must be reported as part of the performance declaration. To provide understandable information to the product users, a class system was proposed by some of the Member States to differentiate the VOC emission performance into five levels. According to the proposal, four performance characteristics are evaluated to allocate a product to a VOC emission class. The overall feedback to the proposal was positive.

Book Synopsis An Experimental Investigation on the Indoor Environmental Conditions on Diffusion Coefficient of VOCs in Building Materials by : Yashar Farajollahi
Download or read book An Experimental Investigation on the Indoor Environmental Conditions on Diffusion Coefficient of VOCs in Building Materials written by Yashar Farajollahi and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the energy crisis in 1973, efforts were made to design constructions more airtight to be energy efficient. Since then, sick building syndrome (SBS) has been reported more often as a result of poor indoor air quality (IAQ). Among the proposed strategies to improve IAQ, source control is determined to be the most effective approach. Because of their large surface areas permanently exposed to the indoor environment, building materials are suspected of playing an important role in determining IAQ. Source-specific control, however, requires adequate knowledge about the extent of volatile organic compounds (VOC) emissions of materials so that in decision-making stages, only products with lower emission rates will be chosen and installed. Hence, knowing the characteristics of building materials (diffusion and partition coefficients) is necessary. Moreover, these data are needed as input parameters for VOC emission simulations, which presently suffer from the lack of a database of emission characteristics of materials. Therefore, this study has characterize building materials by measuring their diffusion coefficients (D) in different environmental conditions. Based on the twin-chamber method, an experimental set-up was developed to determine the D of five VOCs (octane, isopropanol, cyclo hexane, ethyl acetate, and hexane) for ceiling tile as the building material. By using Fick's law, D was calculated and linked to physicochemical properties of VOCs. The method used also allowed us to investigate the influence of temperature, humidity, and the mixture of VOCs on D. Based on obtained results, a systematic parametric study was conducted to quantify the importance of investigated factors. It was found that among different physicochemical properties, the D is positively related to vapor pressure. Additionally, no significant difference was observed between the D of a single VOC and that of a mixture of VOCs. Also, it was observed that temperature and humidity (in the range of a typical indoor environment) had a minor effect on the measured D.

Download or read book Toxicity of Building Materials written by Fernando Pacheco-Torgal and published by Elsevier. This book was released on 2012-08-13 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: From long-standing worries regarding the use of lead and asbestos to recent research into carcinogenic issues related to the use of plastics in construction, there is growing concern regarding the potential toxic effects of building materials on health. Toxicity of building materials provides an essential guide to this important problem and its solutions.Beginning with an overview of the material types and potential health hazards presented by building materials, the book goes on to consider key plastic materials. Materials responsible for formaldehyde and volatile organic compound emissions, as well as semi-volatile organic compounds, are then explored in depth, before a review of wood preservatives and mineral fibre-based building materials. Issues related to the use of radioactive materials and materials that release toxic fumes during burning are the focus of subsequent chapters, followed by discussion of the range of heavy metals, materials prone to mould growth, and antimicrobials. Finally, Toxicity of building materials concludes by considering the potential hazards posed by waste based/recycled building materials, and the toxicity of nanoparticles.With its distinguished editors and international team of expert contributors, Toxicity of building materials is an invaluable tool for all civil engineers, materials researchers, scientists and educators working in the field of building materials. - Provides an essential guide to the potential toxic effects of building materials on health - Comprehensively examines materials responsible for formaldehyde and volatile organic compound emissions, as well as semi-volatile organic compounds - Later chapters focus on issues surrounding the use of radioactive materials and materials that release toxic fumes during burning

Download or read book Ecological and Health Effects of Building Materials written by Junaid Ahmad Malik and published by Springer Nature. This book was released on 2021-08-07 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the present adverse effects of using precarious building materials on the ecology and human health. Also, the detailed discussions on the novel and greener construction materials and their utilization as an alternative to the conventional harmful existing methods and materials are also presented in the subsequent chapters. This book helps to fill the research gaps in the existing prior-art knowledge in the field of sustainable construction and green building materials and methods giving due importance to ecology and health, specifically to the fields of sustainable structural engineering, sustainable geotechnical engineering, sustainable road engineering, etc. This book helps in achieving a sustainable environment through possible adoption of innovative and ecological construction practices. Hence, this book acts as a practical workbook, mainly for the academicians and practicing engineers who are willing to work toward the consecrated building industry. It is a well-established fact that the constructions of the engineering structures consume more and more earth resources than any other human activities in the world. In addition, the construction-related activities will produce several million tons of greenhouse gases, toxic emissions, water pollutants, and solid wastes. This creates a huge impact on environment and causes severe health issues on humans and animals. It is thus important to create an eco-friendly construction environment which can satisfy the ecological and health requirements.
Book Synopsis Measurement of Diffusion and Partition Coefficients of VOCs in Dry Building Materials by : Zhong-Hong Zhang
Download or read book Measurement of Diffusion and Partition Coefficients of VOCs in Dry Building Materials written by Zhong-Hong Zhang and published by . This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building materials, as a source of contaminant, such as volatile organic compounds (VOCs), and a sink of those pollutants, can significantly affect indoor air quality (IAQ). Physical models have been developed to predict volatile organic compound emissions from building materials. These results are helpful in adopting strategies to control the pollutant source. Therefore, experimental methods have been established for measuring input parameters to these models, such as diffusion coefficient (D), partition coefficients (K). However, currently available data of diffusion and partition coefficients are limited. Moreover, the effects caused by the physicochemical properties of VOC are not completely observed. Hence, it is requisite that a comprehensive investigation on the relationship between diffusion and partition coefficients, and the physicochemical properties of VOC be conducted. The twin chamber method was chosen in this research. The effects caused by physicochemical properties of VOC, such as molecular weight, vapor pressure, boiling point, and polarity, were investigated.

This Information Paper provides data about the criteria required by labelling schemes for flooring adhesives and evaluates the test methods used to define 'low-emission' products. Tables show the results of BRE tests on two types of solvent-based adhesives for flooring, a 'low-VOC' adhesive and four 'solvent-free' adhesives.
Book Synopsis Screening and Selecting Building Materials and Products Based on Their Emissions of Volatile Organic Compounds (VOCs) by : AT. Hodgson
Download or read book Screening and Selecting Building Materials and Products Based on Their Emissions of Volatile Organic Compounds (VOCs) written by AT. Hodgson and published by . This book was released on 1996 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cost of emissions tests and other factors have discouraged nearly all but the largest product manufacturers from obtaining emissions data. Emissions data, where available, require toxicologic evaluation before design professionals and other potential purchasers can use them. The absence of health effects information at the low exposures likely to occur from normal indoor uses of most products and materials increases the uncertainty in any such evaluation. The complex mixture emitted by most products poses an additional interpretation problem.
