Air tightness is an important property ofbuilding envelopes. It is a key factor indetermining infiltration and related wallperformanceproperties such as indoor airquality, maintainability and moisturebalance. Air leakage in U.S. housesconsumes roughly 113 of the HVAC energybut provides most of the ventilation used tocontrol TAQ. The Lawrence BerkeleyNational Laboratory has been gatheringresidential air leakage data from manysources and now has a database of morethan 100,000 raw measurements. Thispaper uses a model developed from thatdatabase in conjunction with publicallyavailable data for estimating air leakage as afunction of location throughout the US.
