In the early stages of the project on thermal performance of our experimental masonry building, measurements were made to determine the magnitude of air exchange between the building and the surrounding chamber during the process of cyclic temperature changes. Since wind forces were negligible during the testing period,the major driving force influencing the change of air was the thermal difference between the air inside of the building and that of the surrounding air in the chamber.

Three identical houses in Houston, Texas were extensively instrumented for measuring their air conditioner energy consumption and ceiling and duct heat-gain rates. Comparative tests were conducted to investigate differences in house performance due to increased attic ventilation. The performances of a roof-mounted power ventilator, a ridge vent, and wind-driven turbines were compared to the performance of soffit venting meeting the requirements of the HUD Minimum Property Standards.

Flow patterns at ground level in groups of buildings result from the complex interaction between the wind (impact, average speed distribution with height, and turbulence) and the buildings themselves (shapes, sizes, arrangements, etc.). The

The air change rate in a single story office building was measured using atracer gas technique. The air change rate was determined by the rate of decay method using sulfur hexafluoride as the tracer gas. A total of eight tests were conduc

A large number of developments are under way in the United States of America aimed at providing new high efficiency, space heating equipment for existing and for new single and two family dwellings. The majority of these developments are s

For use in various wind engineering applications, it is desirable to have a consistent relationship by which to project height variations of both 'instantaneous' winds and parameters of the wind speed probability distribution. The power

Infiltration and its effects, measurements, calculations, and typical values are presented and discussed.
