Study on the Evaluation of Regional Building Energy Efficiency Rating According to the Insulation Performance of Double Skin Window in Apartment Houses Expanded Balcony

발코니 확장형 공동주택의 이중외피 창호 열성능에 따른 지역별 건축물에너지 효율등급 평가

In order to handle the crisis about energy-environment problem, it is necessary to develop the future-oriented and innovative energy technology in architecture area. So the development of new technology for energy saving and alternative energy use has been spurred in this area. Double skin window system, which is an active covering to respond to the exterior change of the environment, is the skill that can reduce the indoor cooling and heating load and the environmental architecture can be realized. This study works out U-value of windows using the window-simulation program with the development and study of the double skin. In addition, the effect of the double skin insulation on the efficiency rating has been analyzed, applying to the certification system of the building energy efficiency rating which has implemented.
