지역별 기후에 따른 비주거 건축물 패시브 수준 단열기준 연구

Abstract

This study proposes an appropriate level of insulation standards by region through annual heating energy requirements according to regional climate. The reference buildings out of non-residential buildings approved by the energy saving design standard for buildings were derived in the previous study, in which the annual heating energy requirements for each building were as follows when the insulation standard for building members in four regions (Pyeongchang, Seoul, Gwang-ju, and Jeju) suggested by the energy saving design standard for buildings: 29.8 kWh/m 2 in Pyeongchang,17.5 kWh/m 2 in Seoul,14.4 kWh/m 2 in Gwangju, and 16.7 kWh/m 2 in Jeju. To satisfy the passive level of insulation standards for these buildings, in case that roof/floor of buildings in Pyeongchang and Seoul was 0.2 W/m 2 K, the minimum window thermal transmittance should satisfy 0.9 W/m 2 K and the minimum wall thermal transmittance should satisfy 0.1 W/m 2 K in the case of Pyeongchang. On the other hand, the minimum window thermal transmittance should satisfy 1.5 W/m 2 K and the minimum wall thermal transmittance should satisfy 0.14 W/m 2 K in the case of Seoul. For Jeju regions, the minimum wall thermal transmittance should satisfy 0.34 W/m 2 K to meet the passive level of buildings. Based on the above results, the thermal transmittance of each member by region should take the outdoor climate condition of the region into consideration to satisfy the passive level of buildings.
