The exfiltration and infiltration that are caused due to building's external and internal pressure difference occur heat loss from the building envelopes and cause displeasure to residents. Therefore, enhancing air tightness is a very important part in the building. The purpose of this study is to investigate the performance of air tightness at an apartment house. First of all, we enhanced air tightness of some houses in apartment and conducted blower door test in order to measure air leakage rate. Then, those results were applied to PHPP. On the basis of these data, we compared and analyzed each of the five cases which were selected according to the each part of air tightness. In addition, performance of air tightness was evaluated in accordance with enhancing housing performance gradually. Analysis results on air tightness are discussed in the paper.
