LoginThe R-values of permeable insulation systems are generally determined in test apparatus designed to assure one-dimensional heat transfer and to assure no air intrusion effects. Such classical R-values are used to help describe insitu heat-tra
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.
Discusses minimum ventilation necessary for occupied buildings and finds that occupiers minimum needs are based on dilution of body odours and that in Britain a high ventilation rate is necessary to reduce humidity.
Notes that reduced infiltration and ventilation rates in buildings can lead to higher levels of indoor air pollution. Discusses three indoor-generated pollutants : nitrogen dioxide, formaldehyde and radon.
Reports results of studies conducted in Switzerland in small apartment buildings. Air change rates were measured in ten different apartment buildings using N2O as a tracer gas.
Reviews existing methods for the prediction of infiltration rates and the factors influencing the pressure difference across buildings. Describes experimental procedure used in tests conducted in wind tunnel.
Describes continuous measurements of wind induced pressure differences across the exterior walls of two schools taken over a period of 8 months.
The overall air leakage of high-rise buildings cannot be measured using a full pressure method because of the large volume involved.
Weatherstrip for windows and doors were studied by full-scale tests with regard to airtightness, closing force and ageing properties.
States that the calculation of transient pressures in buildings requires the estimation of the rate of air leakage through various paths. Gives an expression for infiltration through a wall component.
Describes series of wind tunnel investigations leading to development of a procedure for estimating wind pressure forces on low-rise building which is part of a large group of similar buildings.
Discusses in general terms energy consumption and energy requirements and the testing and checking of buildings. Gives principles of thermography and discusses the influence of various parameters on the thermography of buildings.
Provides table showing that annual heat loss through windows in U.S. accounts for about 5% of total energy consumption, or around 1.5 times energy derived from oil transported by alaskan pipeline, costing $30 billion annually.
Surveys factors influencing roof design with respect to energy conservation. Discusses thermal insulation, condensation, ventilation and insolation.
Describes portable apparatus used to measure the air leakage of houses. A fan is used to exhaust air from the house and the air flow rate is measured.
Reports measurements of air infiltration made on two mobile homes, identical except that one was treated with sheathing board and the other caulked.
