LoginReports on a study conducted to determine the impact of different ventilation rates on office building energy use, first cost, and peak electrical demand.
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.
Reports on experiments carried out on models with trough roofs in order to study the influence of parapet height and wind turbulence. The models were exposed to both turbulent shear flow and a smooth uniform flow. Pressure coefficients were c
States that it is accepted practice to determine wind effects on and around a building by measurements in a scaled model in a boundary-layer wind tunnel. At large scales of reproduction it is impossible to simulate the entire depth of the atm
Investigates the relationship between fuel consumption in a multi-storey block of flats and climatic exposure.
Assesses the impact of energy-conserving retrofits on air leakage and indoor air quality for several houses that are part of a weatherization programme in the Pacific Northwest offered by a power and light company.
Describes a scale model test technique designed to estimate building ventilation flow rates due to wind as a function of its primary variables.
Outlines a method for measuring air infiltration using the tracer gas decay technique. SF6 is introduced into a building, and once it is well mixed, container samples of air (in this case plastic bottles) taken over a period of time are analy
Reports on 2 methods of measuring ventilation rates in the 8-storey San Francisco Social Services Building, using occupant-generated CO2 as a tracer gas.
Gives a method of calculating the rate at which air enters a building, and how long it takes to reach a steady state, given the area of the door, the volume of the building and the air change rate caused by infiltration when the door is shut.
Uses "Track Etch" detectors to measure nearly 40000 time-averaged radon concentrations in Canadian, Swedish and US homes. In some areas indoor exposure rates exceed 20 pci/l in as many as 15% of homes surveyed.
Notes the high heat loss in Canadian houses due to air leakage and condensation problems caused by uncontrolled moisture movement into the exterior wall structure.
Examines the fundamental building heat loss calculations. Points out some anomalies in the traditional view of room thermal behaviour.
Gives an account of the results of research into ventilation and radiation in buildings, including one-family dwellings and blocks of flats.
Examines 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.
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.
