창호 구성 요소에 따른 난방에너지 절감율 예측에 관한연구-공동주택을 중심으로

Abstract

This is study on the glazing performance of the apartment house to predict energy saving rate when the early design stage by calculating heating load. there are various factors of the window type in apartment building to save energy such as window’s U-value, SC or SHGC, window wall ration, frame factor, sunshade coefficient and so on. In this study, we analyzed the heating load focused on the U-value, SC and window wall ration using variable heating degree days method for a small and middle size units 59㎡, 84㎡, respectively. Each cases were calculated heating load of the real models compared to standard model to predict energy saving rate. From those cases it was drew the conclusion that were window’s U-value , SC and window wall ration for the small and middle size units to expect 10% energy saving rate at least.
