Abstract

Appropriate evaluation of thermal insulation property of structural member and valid control of cooling/heating energy are important for improving building's energy efficiency. The typical heating system of house in Korea is the floor heating one. The radiation heating system is not only appropriate to climate and geographic conditions of Korea, but also advantageous to provide emotional comfort by the warm feeling of floor. Based on living conditions in Korea, scaled models of the wooden house and concrete house were designed. The ceiling was made of styrofoam insulation and the four sided walls and bottom were made of plywood and concrete, respectively. The floor was heated by heating film. Indoor vertical temperature distributions by floor heating system were measured by thermocouple, and surface temperatures on walls were measured by infrared thermography. Also, thermal insulation property of wooden wall was evaluated to build database for improving energy efficiency of wooden building. It is expected that collected data during tests of various types of floor and wall composition could be referenced for evaluating thermal environment of actual conditions of houses.

구조용 부재의 단열성능에 대한 적절한 평가와 냉난방에너지에 대한 합리적 제어는 건물의 에너지효율을 향상시키기 위하여 매우 중요하다. 한국의 일반적인 주택 난방방식은 바닥난방이다. 이와 같은 복사난방방식은 국내의 지정학적인 조건 또는 기후에 적합할 뿐만 아니라 온열감에 따른 정서적 안정감을 준다는 장점을 가진다. 국내의 바닥난방시스템을 적용하여, 목조공간과 콘크리트조 공간을 대상으로 축소모형을 제작하였다. 천장은 스티로폼으로 단열하고 벽과 바닥은 각각 합판과 콘크리트로 구성하였다. 바닥에는 난방필름을 부착하였다. 바닥난방에 따른 실내의 온도분포는 열전대로 측정하였고, 벽체 표면의 온도는 적외선 열화상 카메라로 측정하였다. 목조주택의 에너지효율 향상을 위한 데이터베이스 구축을 위해 축소모형의 단열성능을 평가하였다. 다양한 벽체와 바닥구성을 지닌 모형들의 단열성능평가 자료는 실제 주택의 열환경 분석시 참고기준으로 이용될 수 있을 것으로 기대된다.
