LoginUses wind tunnel model studies of houses to determine how best to reduce the surface pressure variations from wind and the associated air infiltration emphasizing the correct placement of suitably modelled coniferous trees.
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.
Tests a room-size, residential air-to-air heat exchanger for effectiveness of heat recovery. Conducts experiments in a small wood frame building, the Test Chamber, on the roof of the lab building.
Examines and tests a number of commercial air-to-air heat exchangers to determine their performance as installed in each house.
Presents various measurement and inspection techniques for assessing the thermal performance of the exterior envelopes of buildings.
Subjects 11 private dwellings at Taby and 5 at Brunna (all 2-3 yrs old) to repeated airtightness tests over a period of two years. Finds the largest leakage is 2.5 ach and the mean leakage is 1.6 ach.
Describes a computer program developed for the analysis of residential building thermal loads and space heating and cooling energy use.
Describes a climatic chamber used to measure the concentration of formaldehyde and other volatile substances which may be emitted by furnishing and building materials.
Describes a study to map the ground wind conditions in the housing area Kroksback in Malmo, and to study the effect of various proposed measures to improve the wind environment.
Discusses the possible effects of wind, stack effect, vents and fans on air leakage, and the influence of air leakage openings and the location on the pattern of air flow through buildings.
Reviews the energy conservation features employed in most low energy houses in the Prairie region including airtightness (by application of a vapour barrier), increased thickness of insulation, air-to-air heat exchangers and south-facing windows.
Airflow window units are a combination of energy efficient fenestration and adjustable shading device, consisting of a double-glazed outer sash and a single-glazed inner sash, with venetian or louvered blinds in between. Space air is admitted
Presents data on the air infiltration and ventilation rates in 2 large commercial buildings. One building is a 4 storey, 10000m2 office building near Glasgow, Scotland; the other is a 26 storey, 100,000m2 skyscraper in Newark NJ.
To experimentally determine the repeatability of pressurization test results, pressure tests a home about 80 times in one year. Studies the effect of weather conditions on test results, along with changes in the results over time.
Conducts tests over a period of 18 months in a house near Knoxville Tennessee to determine the effect of forced ventilation on the infiltration rate. Uses an outside-vented electric dryer as the power vent.
Describes a simple method to calculate the leakage area of a house regardless of design or weather conditions. The leakage area is used in the LBL infiltration model to calculate infiltration for any weather condition.
Studies moisture conditions in homes in 2 studies. In one study, 17 homes in 4 states were probed in mid-March 1977, and all moisture content levels were found to be within the acceptable range of equilibrium moisture contents.
Discusses the ASHRAE Standard 62-1981 "Ventilation for Acceptable Indoor AIr Quality", and extensive field measurements of ventilation.
Presents a model for computing the infiltration and air flow between rooms of a multi-room building in terms of basic principles of fluid mechanics. This model has been incorporated into a comprehensive loads-predicting computer program.
Summarises in tables the energy consumptions of a block of flats and a single house demonstrating how the share of energy consumed for fresh air heating and domestic hot water supply increases significantly in line with improved thermal insulati
Adduces the economic advantages of weatherstripping for energy conservation, performance criteria and future developments in materials and fixings. Mentions the advantageous psychological response of personnel.
