사무공간의 수평차양과 차폐계수 변화에 따른 방위별 부하 절감 방안에 관한 연구

The purpose of this paper is to suggest the possibility of coolingㆍheating load reduction in office space when changing overhang length and shading coefficient. A tendency of coolingㆍheating load is different at all compass bearings by reason of a change of transmitted solar radiation. Therefore, an azimuthal plan of a building is an important factor for coolingㆍheating load reduction. Among the design factors of a building skin, overhangs and shading coefficient have influence on transmitted solar radiation and coolingㆍheating load. For this study, e-Quest which is developed by Department of Energy in U.S.A performed a simulation for the building's cooling' heating load. In light of the result, Coolingㆍheating load is decreased when changing overhang length and shading coefficient. But a quantity of colingㆍheating load reduction appears different from each azimuth angle.
