    Air leakage is the single most important quantity in the determination of air infiltration in residential structures. Air leakage is most commonly measured using the fan pressurization technique [ASTM Method for Determining Air Leakage Rate by Fan Pressurization Test (E 779-81)]; the data gathered with this method are often used to determine a leakage constant and a flow exponent. In this report, data gathered from the literature are compiled into a list of leakage constants and flow exponents, and the variability of these values over climate and housing types are examined.
