Abstract

Infiltration is air flow that occurs through cracks in buildings. According to level and kind of infiltration, the cooling load and heating load in buildings may increase. In this study I conducted field measurements to evaluate air tightness in 27 new apartment units. Field measurements for new apartments was the focus. For the de-pressurization method, the equipment utilized to gauge airtightness included KNS-5000C and KNS-4000 which were installed on the window in order to measure indoor air leakage. The results are summarized as follows. The average ACH50 of a $59m^2$ APT was 3.98, 3.82 for a $84m^2$ APT, and 2.73 for a $114m^2$ APT. The total average ACH50 of 27units was 3.51.
