제로에너지 대응 주거용 건물 구현을 위한 U-value 0.15급 외피시스템 적용 및 에너지 성능 분석 연구

External insulation System (U-value 0.15) has been developed to minimize the energy loss through the building envelope. This study investigates the case review of external insulation System installation and the evaluation of energy performance. As a result of the evaluation of thermal performance using infrared methods, there was any heat bridge effect that occurred. It turned out to be 87% reduction on heating energy consumption compare to the current multi-unit dwelling by using CE3, energy simulation program.
