커튼월 창호의 간봉 변화에 따른 열적 성능 평가 분석

Entering the time of high oil price, seriousness of an energy effect sector has given a huge impact and the importance of energy is growing. Especially, in building energy, window system is very important component because most of energy flows through window system. To reduce energy loss through window, this study evaluates the insulation performance of curtain-wall window according to various spacer. Spacer props each glasses and also insulates thermal flow between glass and frame. Thus, this study investigates the kind of spacers and their thermal performances and applys on curtain-wall window system to calculate U-value. By using Therm 5.2 and Wiindow 5 (LBNL) simulation program, this study predicts the insulation performance of windows and proposes which spacer reduce more energy loss.
