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, $CO_2$, CO, indoor temperature, and relative humidity. As the result of pre occupancy measuring, the houses that revealed the lowest TVOC concentration or HCHO concentration were satisfied with "the standard for newly built apartment houses". Therefore, IAQ by the wooden structures is considered to be in good condition. However, in cases of partial value exceeded the standard, the reason is analyzed to be the 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 the reason. As the result of post occupancy measuring, every value except of one subject's TVOC concentration was lower than pre occupancy, explaining the importance of natural ventilation.

본 연구는 목재를 이용하여 축조한 주택에 친환경마감재를 달리하여 조성한 후 실험실의 실내오염물질 방산 저감에 미치는 영향에 대해 검토하고자 하였다. 측정 결과 모든 시험실에서 벤젠, 톨루엔, 에틸벤젠 및 스티렌의 함량이 신축 공동주택의 실내공기질 권고기준치 이하로 나타났다. 실험실 R1-1과 R2-1에서 다른 종류의 벽지를 사용함에 따른 차이를 본 결과, 황토 벽지를 사용한 R1-1에서 상대적으로 높은 자연적인 VOCs (Natural VOCs)값을 얻었으며, 인위적인 VOCs (Anthropogenic VOC) 및 총 VOCs (Total VOCs)의 함량도 높게 나타났다. 실험실 R1-2와 R2-2에서 대나무숯 패널의 유무에 따른 방산특성을 비교한 결과 대나무숯 패널을 설치한 시험실에서 AVOC 함량이 높게 나타났는데 이것은 패널부착 시 사용된 접착제에 일부 영향을 받은 것으로 판단된다. 시험실 R1-3(거실)은 나머지 4곳의 시험실(침실)에 비해 낮은 TVOC 함량을 나타내었고, 다른 시험실과 비교하였을 때 TVOC에 대한 NVOC의 구성비륭이 높은 것으로 보아 마감자재로 사용한 편백의 영향을 받은 것으로 판단된다.

This study is intended to derive the adaptive reuse techniques through the history and aspects of new construction, extension, repair, and other works, limited to the deep and narrow lots facing Seongan-gil and Nammun-gil in Nammun-ro 2 ga of Cheongju, the historic urban area. The results are as follows. 1) In the case of newly built reinforced concrete buildings, the central part of the top floor of the residence or all floors are opened to the open space(void) to facilitate lighting and ventilation. This is developed as a convection phenomenon due to the temperature difference from the slits between buildings, which affects the entire air flow of the block. 2) The buildings of extension and repair are composed of two-story masonry or steel frame, both the front store facing the road and the house on the back, but it looks like one because it is in contact with each other. If only a small gap between the front and rear buildings is restored to an external space or a space equipped with sun light, a small breath can be provided in lighting and ventilation. 3) The existing two-story wooden stores and houses have lost their external space due to repairs. With minimal intervention to restore the small courtyard, slits, and space under the eaves, it will not only improve lighting and ventilation, but also create a unique appearance as a segment of the elongated store.
