LoginCompares the new draft standard with the 1959 original. More sophisticated mathematical methods and meteorological data processing has necessitated the revision.
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.
Describes pressure method for testing whole houses for air leakage. States main advantages compared to tracer gas technique are that equipment is inexpensive, easy to handle and so well adapted to routine tests.
Describes retrofitting a wood-frame residence in three stages to reduce its energy requirements for heating and cooling.
Gives a summary of the work in building thermography in the scandinavian countries, especially Sweden. Deals with the principles of thermography, how to detect thermal resistance deficiencies and air leakage.
Reports measurements of air pressure differences to determine influence of wind on air flow directions through door and window gaps.
Describes briefly mechanisms and sources by which air infiltration occurs in dwellings. Compares leakage rates through windows and through houses with european standards to illustrate values that can occur in the U.K.
States that ventilation needs can be identified from a study of people's behaviour. Reports results of regular systematic observations of open windows in a group of scottish houses which confirmed earlier work in Britain.
Presents method for collecting air infiltration data in a large sample of dwellings. The method consists of a tracer gas dilution technique using sulphur hexafluoride and employing air sample bags which are analyzed in a central laboratory.
Discusses the mechanisms which govern natural ventilation. These are wind speed, flow, characteristics of openings in buildings and pressures generated at building surfaces by wind and temperature difference. Gives formulae for simple cases.
Reviews the requirement in building regulations for cavity barriers in roofs.
Proposes general method to identify contribution of resident-dependent effects to observed variability of energy consumption in similar houses.
Describes the two major methods of measuring air leakage in buildings; the tracer gas method and the pressure method.
Briefly outlines the approach used and the results obtained by computer modelling in estimating the magnitude of natural ventilation in irish housing. Concludes that in general air-change-rates in irish housing are excessive.
Treats methods of determining energy losses in a building given in 1975 swedish building regulations. Presents findings of a number of measurements using pressure method and thermography carried out during 1977 and winter of 1978.
Treats report investigating results of door opening in terms of energy loss and changes to indoor climate. In 3 sections.
Reports investigation of airtightness of two types of industrial wall when subjected to a differential pressure across the wall construction.
A bibliography of references on the subject of air infiltration, lists references in alphabetical order of author and gives short index to broad subject headings.
Reports tests made on a mobile home to evaluate its thermal performance. Describes home, instrumentation and test procedure. Gives energy consumption as a function of indoor-outdoor temperature difference.
Reports some results of field measurements of radon levels in apartments and houses and shows that summer measurements with high natural ventilation rates are generally lower than winter measurements.
This is a revision of the original standard, published 1959.
