LoginInfiltration heat loss has become more important in the energy loss of modern buildings. It depends on a variety of factors. Computer analysis points to the effect of storey number, ground plan features and exhaust ventilation systems.
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.
The growing interest in the response of structures to turbulent wind forces and the realization of the important role played by root-coherence in the prediction of such response has led to the proposal of several expressions for the power
Unnecessary air infiltration ,draftiness, in buildings can be a major cause for excessive energy consumption.
In energy balance of buildings the ventilation losses are a big part, and this part is getting relatively bigger the better the enclosure of the building is insulated.
Presents the first of two sections of report 34020, detailing measurements carried out over the winter period of 1975/76 in Swiss dwellings with mainly hot water heating and some extract ventilation in kitchens and bathrooms.
The second of two sections of a report of air change measurements in the winter period 1975/76 of non-air conditioned buildings in Switzerland, chiefly dwellings.
Investigates energy balance of centrally heated flat at coastal town of Kijkduin, based on daily figures of gas consumption and ventilation losses derived from meteorological conditions.
Reports preliminary research directed towards developing a new method for measuring the air leakage property of an enclosure. The low-frequency acoustic impedance of the enclosure is measured by an infrasonic method.
Reviews tracer gas methods for measuring ventilation rate and discusses the diffusion of gases. Describes four tracer gas methods; rate of decay, equilibrium concentration, transfer index and constant concentration.
Reports investigation whose object was to devise a quick and simple method for checking the airtightness of a whole building. Describes pressurization of building and gives results from 20 single family houses and five multifamily buildings.
Presents a method of analysis to separately quantify the amounts of heat loss due to transmission and to air infiltration. The analysis is based on daily gas and electricity readings for a flat.
Reports comparison of three computer programs designed to calculate room air temperature and heating loads.
Describes the first stage of an investigation designed to simulate in a wind tunnel the full scale wind pressure measurements made by the Building Research Establishment on the Aylesbury test house.
This is done by means of a fan pressing air into the interior of a not air-tight greenhouse.
