AbstractThis paper describes an experimental procedure for determining the air leakage characteristics of the exterior walls of buildings. The technique consists in pressurizing the building with the supply air system and recording the supply air flow rate and the resultant pressure differentials across the walls. The study of the results obtained makes it possible to establish an air flow coefficient and exponent for exterior walls. By applying this method to air flow rates and pressure differentials obtained using a computer-simulated building, it is possible to verify the procedure and confirm that the results obtained correlate closely with air flow characteristics used in the simulation. The air leakage properties of the exterior walls of four buildings, determined using this method, are also presented.
