공동주택 인동간격에 따른 세대내 일사 유입량과 난방부하에 관한 연구- 판상형 아파트를 중심으로

Purpose: Building energy saving standard is being strengthened every year. But, there is not enough inflow solar radiation standard for saving heating load of residential part. The purpose of this study is to analyze the effect of the shadow according to the distance between apartment, to compare the Window Transmitted Solar Radiation Energy and the heating load. So as to do verify solar radiation and heat load, Design Builder simulation was conducted. The results of the this study are as follows. First, The Korean Building ACT and energy saving standard proposes the minimum building distance for sunshine, but, there is not enough standard about solar energy for heating energy saving. The solar standard is needed for is not daylight hour but solar radiation energy. Secondly, when the distance between apartment increased by 150%, solar radiation increased by 17 % and heating load was reduced by 15%. Finally, when the distance between apartment increased by 125%~150%, the middle floor is effective to reduce heating loads according to the solar radiation energy and lower floor is not effective. The lower floor is required other plan for reduce heating load.
