Significance of air infiltration on building energy conservation design standards and codes.

With increased concern for energy conservation, many new standards have been developed. Discusses these standards which are of three types, prescriptive, component performance and performance. Outlines several design approaches toreducing air infiltration. States need for three new standards, 1) the use of pressurization-evacuation test methods to set a construction quality performance standard, 2) the use of ducted outside air with heat recovery for fresh air introduction to super-tight residences, and 3) the use of ducted outside air to fossil-fuel burning units for combustion purposes.
