현장실험을 통한 실외 미세먼지의 공동주택 침입경로 분석

The purpose of this study is to analyze outdoor particle penetration pathways of multifamily housing units depending on building characteristics. For three multifamily housing units in urban area, typical blower-door tests were conducted to measure the leakage areas of suspected particle penetration pathways including ventilation system, drainage, electric outlet, windows frame, and exterior wall. The result showed that the air leakage was dominant in the order of window frame, ventilation system, pipe penetrating exterior wall, and electiric outlet. And the ratio of leakage areas on window frame was proportional to the built year of multi-family housing units.
