AbstractThe topic of air leakage in buildings is discussed. Reasons for minimizing air leakage are presented. Measured values from tests of the air leakage of groups of both detached residences and larger buildings are given. For detached residences, air leakage measurements vary from less than 0.5 air changes per hour at 50 Pa, to more than 50 air changes per hour at 50 Pa. For larger buildings, a small sample of measurements indicated that the air leakage rate per unit surface area of the buildings ranged from 0.6 to 5L/s/m [2] at 75 Pa. Care must be taken when sealing a building to ensure that adequate levels of ventilation are maintained. Most often this is accomplished by providing mechanical ventilation.
