LoginSuggests many ways of reducing outdoor air admitted to a building. Notes importance of measuring minimum air flow to ensure adequate ventilation.
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.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
Weatherstripping windows and doors. Calfeutrement de fenetres et des portes | 1979 | English, French
Describes different types of weatherstrips and reports ageing and deformation test on strips and tests on air tightness and closing force.
Describes wind tunnel measurements made on a model of a tall building surrounded by lower buildings under various combination of wind speed, wind angle and air temperature.
Air infiltration effects on the thermal transmittance of concrete building systems. | 1979 | English
Describes field measurements of thermal transmittance using portable guarded hotbox equipment on 2 types of concrete walls. Air leakage measurements of these same 2 types of concrete systems were made in the laboratory. Describes test methods.
Presents and explains derivation of simplified heat transfer equation as part of an averaging method to enable perceptive home owner to determine air infiltration. A winter month isselected and the gas meter read daily.
U.S. ventilation systems have been reported to require as much as 50-60% of total energy consumed in buildings and have become popular targets for energy conservation methods.
Outlines parameters governing air infiltration. Discusses problem areas of house to house comparisons of air leakage. Deals primarily with tracer gas procedure as compared with pressurisation/depressurisation approach.
Treats measurements of air infiltration rate in 2 mobile homes - one treated with caulking, the other with continuous sheathing board - over entire heating and cooling season. Concentrates on summertime data.
Describes how in 1960-62 National Research Council of Canada conducted air infiltration measurements on 2 single-storey houses using helium as a tracer gas, followed in 1967-68 by measurement of air leakage characteristics using house pressurisati
When attempting to determine heating/cooling requirement of a home a difference in infiltration can drastically affect heating/cooling requirement imposed on air conditioning system.
Practical measurement has shown that gasoil and candle flames provide constant tracer gas sources. Suggests their use for meaSuring ventilation.
Refers to previous article treating application of theory of graphical representation in building services of calculating natural ventilation rates in buildings. Illustrates technique using examples of several buildings.
Reports of tests on wood windows and doors to determine their thermal performance with and without wind.
Reports measurements made on windows in old blocks of flats in Sweden. Measurements were taken of air-leakage through 21 windows under different air pressures before and after the renewal of draught excluders between window frame and casement.
Summarises data on air flow characteristics of walls from U.S.A. and Norway. Reports laboratory measurements on four test walls and identifies main sources of leakage for the different test facades.
Analyses the problem of air management in energy conserving passive solar houses and discusses cost effectiveness of various alternative scheme.
The airtightness of windows is an important feature in deciding habitability. in additional to the conventional, the window sashes featuring improved soundproofing and insulation performance have appeared.
Describes the original series of case studies made by Dick and his associates between 1949 and 1951. Reviews current activities, divided by building types and discusses the problems and needs of future work.
Reviews ideal characteristics of a tracer gas and gives literature review of the subject. Reports tests made on a house in California giving a direct intercomparison between common tracer gases used to measure air infiltration rates in buildings.
