Component leakage areas in residential buildings.

Reviews the published data on component air leakage, and from this compiles a set of component leakage figures for use in estimating leakage areas and their distribution in buildings. These calculations are compared with measurements of leakage areas in 36 houses in different locations in the US. The model predicts leakage area accurately for the average of the 36 houses, while for individual houses the standard deviation is about 20%. Discusses the assumptions and methods to convert other types of component leakage data to component leakage area. Where several types of independent data exist for thesame component, discusses the quantitative differences in terms of possible differences in construction practices.
