공동주택에서의 플러쉬아웃 현황 및 개선방향을 위한 연구

Abstract

Volatile organic compounds in buildings from finishing materials, adhesives, built-in furniture, etc. can cause headaches, atopic dermatitis, etc. for occupants in the buildings. To mitigate this, the Korean government has obligated to flush out the buildings after new construction and before occupancy since 2011. In this study, the current status of performing flush-out in multi-family residential buildings in Korea were analyzed, and its improvement would be proposed. At first, a questionnaire survey was conducted to figure out the current status of flush-out performances targeting a number of construction companies who have already constructed multi-family residential buildings with compliance of the obligation. Through the analysis of this survey, several conditions that need to be improved for flush-out were identified. Secondly, the identified conditions were evaluated in varying conditions using a simulation program to figure out an effective way of performing flush-out rather than as it is. As a result, a flush-out performance period with an appropriate supply air volume, and indoor temperature and humidity were identified to be improved through the survey, and it revealed through the simulation that the flush-out should be performed at least 14 days to reduce the indoor air pollution more than a half.
