신축목조주택의 실내공기질 특성 및 관련요인 분석

Abstract

The purpose of this research is to analyze characteristics and related factors of IAQ (Indoor Air Quality) in newly built wooden houses by measuring pre and post occupancy. The subjects were five wooden houses which were built with similar materials and completed from July to December 2013. Measuring factors were TVOC, HCHO, PM10, , CO, indoor temperature, and relative humidity. As result of pre occupancy measuring, houses that revealed lowest TVOC concentration or HCHO concentration were satisfied with the standard for newly built apartment houses. Therefore, IAQ by wooden structures is considered to be in good condition. However, in cases of partial value exceeded standard, reason is analyzed to be materials of molding, wrapping doors, built-in closet, or kitchen furniture, etc. rather than structure materials. Most PM10 concentration level showed slightly below the standard for occupied multi-use facilities. Remaining of construction dust was considered to be reason. As result of post occupancy measuring, every value except of one subject`s TVOC concentration was lower than pre occupancy, explaining importance of natural ventilation.
