LoginExamines the possibilities of achieving energy-efficient ventilation systems in naturally ventilated homes (which include the use of intermittent extract fans in individual rooms). Discusses factors affecting energy efficiency.
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.
Notes job losses in prefabricated timber housing industry in Sweden and Hjaltevad's endeavours to produce a large series popular house with low-energy characteristics. House is on one and a half floors and has an occupied area of 150 sq.m.
Makes an inventory of different outside wall structures and details their construction with respect to heat losses.
Notes initial airtightness requirements in SBN 1980 and discusses various forms of ventilation. Discusses how tightness testing can reveal location and magnitude of leaks.
Reports the results of over 100 tests of 6 different warm air schemes. The temperatures and the removal of a tracer gas were monitored at several points and the data used to determine the temperature efficiency and ventilation efficiency.
Reports on the problem of increased carbon monoxide poisoning in houses resulting from new energy conservation construction techniques, which improve the airtightness of houses.
Describes method and equipment for measuring air leakage from windows.
Decribes the "collector chamber" method, where a room or whole building is pressurised and the air leaking through the target areas is collected with apressure compensated chamber to a measurement device.
Gives a survey of the weather parameters used for the "Danish test reference year TRY" and the corresponding set of data from meteorological observations made during a 15 year period.
A knowledge of the pressure fluctuations on buildings exposed to strong winds is important for wind loading calculations.
Describes full-scale measurements of wind pressures carried out on a high-rise building situated in an urban area and having an almost rectangular plan.
Describes a technique for measuring air flows between internal zones of houses. Gives the theory of measuring one and two directional flows and describes the equipment used for practical measurements.
Reports on an extension of the metabolic CO2 method for ventilation measurement to a naturally ventilated room having air flow connections with other internal spaces as well as the outside.
Gives answers to practical problems encountered when retrofitting older Canadian houses. The first section gives an overview of a typical house both before and after retrofitting.
Describes the monitoring over a 15-month period of the heat supplied to and heat lost from an unoccupied house in the grounds of the Cement and Concrete Association.
Describes a computer program, Harmon, developed for the simulation of the thermal response of buildings (based on BRE's "admittance procedure") which can be used on mini-computers and utilized at the sketch design stage for the comparative evaluat
Carries out measurements of indoor atmospheric environment in a day nursery and a kindergarten in Denmark, where natural air infiltration supplies the room with only 1-2 m3 fresh air per person and hour under the prescribed occupancy.
Studies a modern energy efficient office building in a series of experiments with mobile laboratories connected on-line with the building. Measures inorganic air contaminants (CO, CO2, NO2). Makes off-line measurements of volatile organic con
Using miniature perfluorocarbon tracer (PFT) sources and miniature passive samplers, tests conducted in the lab and in a typical home successfully demonstrate the utility of the PFT kit as a means for implementing wide-scale infiltration meas
Studies a sample of 58 occupied homes in Rochester NY to assess 1. the effectiveness of construction techniques designed to reduce air leakage 2. the indoor air quality and air-exchange rates in selected airtight houses and 3. the impact on
