건물 냉ㆍ난방을 위한 태양열 집열시스템의 운전특성 분석

The research and development of the utilization of solar energy has been conducted for many years, because of its limitless and pollution-free natural energy. But the solar energy has not been utilized extensively due to its low density, restriction of installation area, and the economic problem. The main building of Daewoo Institute of Construction Technology was constructed to be the top energy saving office building in the Asian area. The annual energy consumption per extended floor space was 160 M㎈/㎡ year, or less than 1/4 of that of conventional office building. The indoor environment has made equal to or better than that of ordinary offices, and excellent livability and functionality have been realized. This study was focused on the analysis of solar system for the basis of measuring data of main building.
