LoginDescribes automatic equipment for measuring thermal comfort based on resultant surface temperature, convective heat flux density, air temperature and relative humidity. Results obtained in an environmental chamber are presented and evaluated.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
Carbon monoxide and nitrogen dioxide were monitored in 12 homes on a real-time basis to determine their transient concentrations, their dispersion through the homes and day-to-day variation in pollutant levels.
Sixty houses built with widely different construction practices and located in different areas in upstate New York were monitored for airtightness (using fan pressurization) and integrated radon concentrations in indoor air, household water,
Describes the measurement of air change rate and airtightness of a mechanically ventilated public swimming bath in Belgium. The relationship between airtightness and air change rate is outlined.
The thermal effects of air flows in building structures have been analyzed by computer simulation.
A research project by the Energy Division is underway to develop and demonstrate appropriate construction techniques for superinsulation (SI) residential construction in Minnesota. Techniques applicable for both new and retrofit SI constructi
Operation of an unvented combustion appliance indoors can elevate pollutant concentrations. Under laboratory conditions, oxygen consumption rates and pollutant emission rates of CO, CO2, NO, NO2, HCHO and submicron suspended particles emitted
A survey of mathematical models of air flow and of ventilation efficiency. Measuring equipment for laboratory experiments is described and the limitations and potential uses of the models are discussed.
Describes in detail a mathematical model of multicell air flow in houses. A worked example is given.
A handbook of constuction techniques for achieving a low air change rate and good insulation in steel buildings. Insulating materials and how to avoid cold bridges are discussed.
Formaldehyde dosimeters have been tested in urea-formaldehyde foam insulated Canadian homes in which formaldehyde levels range from 0.02 to 0.2ppm. Performance of commercial and experimental passive dosimeters was evaluated over 2- to 4- and
Provides the text of the 68 papers presented at the symposium, arranged under the following headings - Plenary session, Advanced developments in ventilation, Control of toxic and explosive contaminants, Advances in tracer gas use, Ventilation for
Describes the evaluation of a new simple passive perfluorocarbon tracer technique for determining air infiltration rates into houses and buildings. The authors explain the methods used and present and discuss their results.
Existing models for predicting air infiltration account for three dominant variables, namely envelope leakage characteristics, indoor-outdoor temperature difference and wind speed.
Subjects covered include: problems of radon, formaldehyde build-up in the home, residential indoor air quality, effect of moisture on other pollutants, epidemiology of indoor air problems, setting standards for recognising harmful concentrations i
