A SIMPLIFIED CALCULATION METHOD OF THE HOUSE INFILTRATION RATES WITH THE BUILDING AIR TIGHTNESS

Abstract

In this paper we present a simplified calculation method of the house infiltration rates with the building air tightness. The characteristic of the method is able to estimate the infiltration rates for combination of out door wind speed and indoor-outdoor temperatuer difference. The proposed calculation method was tested using the measured infiltration data of a experimental house for a year. A results of the comparison between the calculations and measurements showed that the agreement between the prediction and the measurement was also within 0.1 volume par hour.
