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

This paper presents an account, and results, from the U.S. Gas Industry's on-going program to assess the effectiveness of various retrofit actions toincrease the seasonal efficiency of central, gas-fired, space heating, residential furnace

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.

Roof space ventilation is important in warm weather to dry out moisture that may have accumulated in the roof space. It is important to reduce the movement of moisture from the living areas to the roof space and to ventilate the latter by means of vents distributed between the upper and lower parts of theroof to take advantage of both wind action and stack action.

Air leakage characteristics of 192 new windows installed in new residential construction representative of those units commonly installed in the Minneapolis/St. Paul Metropolitan Area have been measured and evaluated. The tested windows represented all major operation types, window material types and manufacturers represented in this market segment. The air leakage data obtained in the field were compared to industry and government standards and manufacturers reports for reference.
