LoginIdentified thermophilic actinomycetes contamination of the forced air systems as the sensitizing agents for most of the cases of hypersensitivity pneumonitis in eight patients.
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.
Describes behavioural studies of the window opening habits of families in 123 houses to show strong seasonal pattern. During winter, window opening is closely related to moisture levels in the external air.
Discusses in theoretical terms complexity of interactions of weather-driven air infiltration by 1) wind and 2) convection induced by indoor/outdoor temperature difference.
Summarises results of research project comprising survey of air tightness and natural air change rates in various types of residential building. Briefly describes equipment for pressurization tests and tracer gas measurements.
Presents simplified methods for the evaluation of the infiltration of air in industrial and public buildings. Relationships are illustrated by examples.
Discusses how building ventilation is affected both by steady mean effect of air pressures and temperatures around and within the building and turbulent nature of the wind causing air diffusion through openings and cracks in the building envelope.
Points out that difficulty in calculating fortuitous ventilation in buildings caused by infiltration means that energy demand of a building contributed by it is scarcely ever known.
Points out that energy necessary to humidify air in a dwelling is usually far greater than consequent decreased sensible heat loss. Provides basic information necessary to calculate moisture deficit or surplus due to air exchange.
Discusses measurement of energy consumption and the large number of factors to be studied. Presents detailed measurements for two blocks of flats in Sweden taken partly during 1971/72 and partly during the oil crisis of 1973/74.
Describes measurement of wind pressures on low-rise buildings at Aylesbury.
Reviews methods of measuring infiltration rates. Describes tests made on a mobile home using carbon monoxide as a tracer gas and measuring the rate of decay.
Reports investigation to devise a simple method for measuring the airtightness of buildings which will provide clear results in conformity with a definite standard, swedish building regulations 1975.
Reports on the air leakage characteristics of the exterior walls of eight multi-storey office buildings in Ottawa.
Notes importance of air motion in shielded buildings in hot and humid climates. Describes wind-tunnel investigations on shielding effect of buildings for a group of buildings comprising parallel rows of identical blocks.
Describes method of measuring the air-change rates using sulphur hexafluoride as a tracer gas. The system comprises a highly portable gas chromatograph with an electron capture detector.
