LoginDescribes research project to find air leakage values of walls of elevator and stair shafts in order to use these values in the design of pressurization systems. Describes method of test and gives results.
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.
Reports study of energy consumption of typical house in Texas. Computer-based model was used to simulate house under different conditions of insulation, infiltration, shading and operation. Gives tables of results of variation in energy use.
Reports detailed investigation of the interaction between group geometry, flow properties and resulting pressure forces on a group of buildings.
Describes test apparatus and method of testing windows for air leakage. This standard has been adopted by the following countries :- Austria, Belgium, Denmark, France, Italy, Netherlands, Spain, Switzerland and United Kingdom.
Reports measurements of ventilation rates made in a nine-story office building. Two methods were used; tracer gas decay rate using sulphur hexafluoride and a direct method when air flow rates through roof vents and exhaust units were measured.
Detailed sets of time-averaged surface pressure coefficients were recorded over the walls and roof of a rectangular building model, set in a simulated high density urban area.
Describes a sampling programme which measured simultaneously the indoor and outdoor concentrations of pollutants at three sites in Zurich during summer and winter.
Presents method for estimating the heat requirements of buildings.
Reports air leakage measurements made in a mobile home using sulphur hexafluoride as a tracer gas. The home was located in an environmental chamber where it was possible to measure and control the temperature outside the home.
Describes a system which automatically operates a small gas chromatograph and measures parts per billion concentrations of sulphur hexafluoride in air. It samples air on a 10-minute cycle and records the response on a strip chart recorder.
Reports the use of thermography for evaluating the effectiveness of a number of different retrofit measures carried out on single family dwellings in Twin Rivers. Discusses the use and limitations of thermography.
An anemometer which was developed for indoor climate research has been modified in order to get the same shape of calibration curve for each anemometer.
The indoor air quality of six homes with gas and electric cooking and gas heating appliances was characterized to determine the level of gaseous and aerosol air pollutants from typical indoor combustion sources.
This paper discusses the flow of air around ideal (cubic) structures on plane surfaces subjected to a turbulent boundary layer wind.
The calibration and use of a shielded dual sensor hot-wire probe, originally developed at McGill University for velocity measurement in highly turbulent and reversing flows, is described.
This paper presents a numerical calculation method for a two-dimensional, isothermal, turbulent room air movement. In this case, the time averaged stream function-vorticity equations were represented by finite differencing approximations
