공동주택에서 외피단열성능기준 강화에 따른 건축물에너지 효율등급 변화에 관한 연구

This study aimed to compare the primary heating energy consumption of regional apartment houses based on the enhanced thermal insulation performance of building envelope standards. The difference of the heating energy consumption based on the enhanced thermal insulation performance of building envelope standards in the southern region, the largest regional difference in primary heating energy consumption, is 10.3 kWh/(㎡ ․year). The difference of the heating energy consumption based on the enhanced thermal insulation performance of building envelope standards in the central region is 8.0~8.5 kWh/(㎡․year) and that of the Jeju region is 0.5 kWh/(㎡․year). These energy consumption differences do not result in building energy efficiency ratings changing. The building energy efficiency ratings have the possibility to be changed.
