외피 투과체 변화에 따른 G-value 평가에 관한 연구

The purpose of this paper is to calculate monthly G-value when changing the glazing and shading device. For this study, e-Quest which is developed by Department of Energy in U.S.A performed the simulation for vertical solar radiation, transmitted solar radiation through windows and the secondary heat flow. Among the design factors of a building skin, high performance glazing, overhangs, venetian blind, and roller blind were used in the simulation. In addition, venetian blind, and roller blind were located at the inner side of the window. In light of the result, monthly G-value was the highest in July in summer for the reason of the rainy season. However, monthly G-value has increased in winter because of low incident angle.
