국내 고층건물의 기밀성능 현황 및 국내외 외피 기밀성능 기준과의 비교

The purpose of this study is to analyze the current status of airtightness of high-rise buildings in Korea. In this paper, the airtightness data of 20 middle to high-rise buildings of Korea were analyzed. In addition, the air-tightness performance of Korean buildings was compared with the those of international building standards for airtightness. As a result, the airtightness of recently constructed buildings tended to be tighter, and the average airtightness of Korean buildings analyzed in this study was 1.9cm2/m2@75Pa. The average airtightness of curtain wall was 2.2cm2/m2@75Pa and punched window was 1.6cm2/m2@75Pa.
