Abstract

The modular construction method is an off-site construction method using built-in structures from the manufacturing facilities. Modular construction is commonly applied to buildings which have relatively smaller and simpler structures than other types of buildings. Although modular building has emerged in the domestic construction industry as an alternative building strategy, previous researches on the environmental characteristics of modular building has not been comprehensively studied. Thus, this study empirically analyzed the insulation performance of thermal bridge and condensation parts of the modular buildings by using IR image analysis, Air-Surface Temperature Ratio method, and temperature difference ratio. The insulation performance analysis was conducted by comparing a modular building and a RC building in Seoul. The results shows that there was no significant difference between insulation performances of RC building and modular building. Furthermore

모듈러 공법은 내장재와 기계·전기 설비 등이 시공된 구조체를 제작 공장에서 건설 현장으로 운반하여 설치 및 시공하는 공법이다. 모듈러 공법은 특히 주택과 같은 소규모의 비교적 구조가 간단한 건축물을 대상으로 활발하게 적용되고 있는 추세이다. 국내건설 산업에 모듈러 주택의 도입된 기간이 길지 않은 만큼 아직 모듈러 주택의 환경적 특성에 대한 연구가 부족한 실정이다. 따라서 본 연구의 목적은 모듈러 주택의 단열성능을 적외선 이미지 분석과, Air-Surface Thermal Ratio 방법, 실내외 온도차비를 활용하여 실증적으로 분석하는 것이다. 이를 위해 실제 서울시에 위치한 준공 후 2년이 경과된 모듈러 주택과 RC 주택을 비교하여 단열성능 분석하였다.
