외단열 건축물 외피 열관류율 성능 현장 측정 연구

The EIFS(External Insulation Facade System) is very a useful and powerful item to reduce thermal load of buildings becausethe EIFS can protect outside heat and conserve inside heat. The EIFS will be mandatory sooner or later because Koreanbuilding energy efficiency regulation will require more high thermal performance of building. But EIFS still has some problemssuch as detachment, deformation, lack of building standards, and performance verification, etc. So, in this study, we examinedregulations and standards on the EIFS and measured actual thermal performance of the EIFS using heat flux sensors. Themeasured heat flux data converted to U-value and it was compared to designed U-value.
