LoginStudies the techniques and issues related to evaluating the airtightness of homes. The first section discusses the physics of air infiltration and the techniques used to measure infiltration rates.
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 a mathematical model for the calculation of the expected values of radon and radon daughter concentrations in indoor air.
States that although the conditions for a comfortable climate are well known - especially temperature and air humidity - increased concern with energy conservation means it is important to discover what effect energy conserving measures have on th
Reports air tightness measures and variations in 14 low-energy houses in Heimdal, plus testing of energy saving measures for exposed detached houses. The air tightness should be considerably improved according to the regulations.
Describes energy measurements carried out on 6 detached single family low-energy houses in Hjortekaer, 1979-1980.
Describes a program which enables a hand-held computer to perform the energy audit calculations used in Building Practice Note No.20 "Estimating energy savings from reinsulating houses".
Describes a model that predicts air infiltration from both wind and temperature influence to within 20%.
The Act (1981.592) on amendments in the Building Ordinance (1959:612) and implementing regulations appertaining thereto in the Building Code come into force on 1st January 1984. The regulations apply only to permanently used houses.
Describes the aims, methods and results of a preliminary study into radon in Swiss house carried out 1981/82.
Evaluates the space-conditioning energy conservation potentials of landscapes designed to ameliorate building microclimates.
Reviews air infiltration measurement methods, prediction models, and flow through components of buildings.
Reviews current knowledge about the sources of a number of indoor pollutants and their concentrations: tobacco smoke, NO2, CO, radon, formaldehyde, SO2, CO2, O3, asbestos, mineral fibres, organics and allergens.
Ventilation and air exchange in buildings and industrial plants can be induced by external winds and by buoyancy forces.
Reviews the literature on wind tunnel modelling of natural ventilation. Lists advantages of using wind tunnels. Discusses strategies for utilizing natural ventilation.
Undertakes a comparison of full scale and model scale internal velocities of naturally ventilated rooms.
Discusses the problems of designing ventilation for small houses. Small houses are considered to be far too elementary and there is no total view of the balance of energy and no regard for the interplay between different flows.
The investigation was divided into several parts: 1, measurements of a mechanical ventilation system, 2, calculation model for this system, 3, measurements of the air leakage of the facades of a flat and 4, calculation model for this flat.
The purpose of the project has been to determine the saving in energy obtained in the practical operation of an FTX-system -that is, a fan-controlled supply and exhaust ventilation system with heat recovery - compared to an F-system, which is sole
Natural and forced ventilation are directly and indirectly influenced by the pressure distribution around a building. Results of full-scale pressure measurements on a typical Swedish timber house are presented.
The heat losses from small houses, due to transmission and ventilation, are estimated. The estimation i s based up on the house owness daily readings of electricity and water meters, and their notes on behaviour influencing the energy use.
