LoginReports a program of research in progress at the Colorado State University to determine the surface pressures on building models immersed in a simulated atmospheric flow.
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.
Gives a brief historical review of the development of wind engineering as a discipline. Discusses the simulation of wind loads on buildings, the development of boundary layer wind tunnels and problems in modelling the natural wind.
Briefly reviews the study of wind flow around buildings. Shows that fundamental theoretical and experimental studies are beginning to produce simple descriptive and mathematical models of flows round buildings.
The objectives of this review are to establish an initial subject-matter base for wind engineering, to demonstrate current capabilities and deficiencies of this base for an engineering treatment of wind-effect problems, and to indicate are
The use of lightwells and courtyards for natural ventilation in high-rise buildings is exaimed using both wind tunnel and field measurements of the pressures and neutral pressure zone caused by wind and temperature differences.
A wind tunnel of open-circuit configuration designed specifically for building aerodynamics is described and its performance is discussed. It has a working section 2 m wide x 1 m high x 8 m long with a maximum wind speed of 20 m/sec under
When an underground parking place is not ventilated frequently enough, it is natural that the concentration of contaminated air cannot be lowered to less than the safety limit.
Examines the economic aspects of energy conservation techniques suitable for retrofitting into existing homes. Includes insulation, storm windows and doors, and weatherstripping.
This article examines a solution procedure which can determine the flow in an air-conditioned room.
Reports wind tunnel investigation of the air flow around single houses and in passages between two single buildings.
Describes experimental method used and results obtained in a series of experiments to investigate characteristics of air flow through cracks in dwellings, including the straight-through, l-shaped and multi-cornered forms found in the construction
Outlines basic requirements for a fresh air supply to a dwelling, which include health, comfort and air for combustion appliances. Discusses feasibility of achieving these requirements by natural and mechanical means.
Air movement into and out of a building is caused by pressure differences created by fans, wind, and/or differences in air density.
The nomograph estimates air infiltration du to wind and the amount of heat removed by any quantity of heated air. It supplements the September HPAC Data Sheet on air infiltration into buildings due to temperature differences (stack effect)
One cause of these discomfort zones is cold air infiltration through window joints. This can be deflected using a warm air curtain.
