LoginDescribes evaluation of two integrated heating and ventilating systems, one a modified warm air system and the other a modified mechanical ventilation system. From the technical viewpoint the systems were found to be efficient.
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.
This paper presents a simple method for estimating the total air change rate of a house with or without mechanical ventilation. The proposed method can be used to assess the effect of a mechanical ventilation system on total air change rates.
This paper reports the findings from tests undertaken in an untight, two-storey, brick-built detached test house.
A multicell air flow computer program is used to determine the influence of 1) open windows and 2) closed internal doors on the ventilation rate of a semi-detached house.
Although infiltration of outside air across the envelope of a building has been considered of prime interest in relation to energy conservation and indoor air quality, it also important to understand the way in which air moves between zones within
If the energy losses due to ventilation have obviously become an important problem since the energy crisis, there is still a lot to be done with respect to the behaviours.
Measurement of air exchange rates, ages of air, and nominal and local ventilation efficiencies in large buildings is often complicated by the building size and compartmentalization, and by the presence of multiple ventilation systems.
Describes use of water tanks to simulate two- and three-dimensional natural ventilation air flows through open doors and windows. Density differences are produced by dissolved salt.
Indoor NO2 concentrations were measured in the kitchen, the living room and bedroom of 612 houses in two different areas in the Netherlands. In asub-sample, personal exposure of the housewives to NO2 was measured.
Effects of a coniferous windbreak on electrical energy use in a 66-unit mobile home park in central Pennsylvania were studied during the winters of 1981-82 and 1982-83.
A large proportion of heated rooms depend primarily on natural convection for the distribution of heat within the occupied zone. A method of predicting air temperature variations with height is presented.
The multiple tracer gas technique of I'Anson et al. has been improved, in order to increase the rate at which samples can be taken.
A test method for determination of air flow resistance of exterior membranes and sheathings is described.
Roof space ventilation is important in warm weather to dry out moisture that may have accumulated in the roof space.
The study, carried out in an atmospheric wind tunnel (reproduction of natural wind conditions, particularly turbulence), quantifies wind flows around built-up obstacles in their realistic location context, and the associated pressure fields.
Describes validation of a simple technique for infiltration measurement in large, multicelled, naturally ventilated buildings by reference to a computer model study and by field measurements in two naturally ventilated office buildings.
The results of exposure chamber and field validation tests of NO2 diffusion tubes are reported. In an exposure chamber about 50 test runs at various relative humidities were performed.
Reviews some of the results of the project "The requirement-adapted ventilation system", which is part of an extensive research project "Indoor air quality and ventilation requirements" begun in Finland in 1983.
Substantial work on ventilation effectiveness has been carried out in Norway and Sweden using tracer gas techniques based on fundamental physical and mathematical concepts.
Lists the basic sources, mechanics, and problems of moisture in houses in the USA.
