Abstract

The purpose of this study is to investigate the air leakage parts and analyze the airtightness in newly constructed apartments. For the study, the blower door and tracer gas tests were used to measure air leakage rate. Four parts in the building were applied and the measurements were conducted to obtain the air leakage rate of those parts. As a result, the air leakage rate was 0.7~1.0(ACH50) when all parts were sealed. On the other hand, the value was 1.6~2.7(ACH50) under unsealed condition. Considering these reults, it can be assumed that the airtightness of newly constructed apartments was quite tight. In addition, the results showed that the parts of the air leakage were mainly affected in order by, the entrance door, windows, mechanic 2 (air system), mechanic 1 (water system), and electric. By improving these parts, it will be expected to improve the airtighteness for residential buildings. Furthermore, building energy can be saved and provide more comfortable environments.
