air leakage

Final report ASHRAE Research Project 438-RP/ Evaluation of the techniques for the measurement of air leakage of building components.

Knowledge of the amount of air leaking into a building through the various building components is important for a wide variety of reasons. Initially the interest in these values was so that estimates could be made on the amount of energy to be added or removed to heat or cool air that was infiltrating into the structure. Selection of new and replacement building materials was done partially on the amount of energy costs that would be saved by the selection of that component.
