국내외 유사 규정 비교 및 외피 유형별 사례 검토를 통한 건물 외피 단열 규정에서의 열교 영향 고려 필요성 분석

다국어 초록 (Multilingual Abstract)

Envelope insulation plays a key role to save building energy consumption. To obtain a high level of insulation performance, it is essential to minimize repeated thermal bridges, which cause substantial heat loss through the building envelope. However, required U-value calculations, prescribed in the Code for Energy-efficient Building Design, assume that there are no thermal bridges and one-dimensional heat transfer occurs. Accordingly, effective U-values of actual buildings are quite different from the U-values prescribed in the Code. The aim of this study was to examine the needs for building envelope insulation regulations reflecting the influence of thermal bridges. A variety of insulation regulations of Korea and many other countries were reviewed and compared. The influence of thermal bridging effects on the insulation performance was evaluated by three dimensional steady-state heat transfer simulations. As results, it was found that effective U-values of cases reflecting thermal bridging effects were 23.8～218.8% higher than those of cases not reflecting thermal bridging effects. Thus, it is necessary to improve building envelope insulation regulations to include thermal bridging effects.
