The research analyzes the arrangement of boiler and hot water header, the method of radiator pipe setting, hot water supply control, hourly heating situation of each room for underfloor radiant heating systems in Korea and suggests an alternative to improve to efficient heating method. One of the best options for install position of hot water distributor is under kitchen sink which is center point of all rooms, according to previous research of the energy saving strategies. When the radiator pipes are arranged to each individual room instead of bedrooms through livingroom and kitchen, it has energy saving effects. For rooms without occupancy according to a time period, hot water supply method should be intermittent heating rather than continuous heating. For this intermittent heating method, individual control of hot water supply is more practical, and it can lead to massive energy savings. The intermittent heating system has time-lag, so it is more effective in energy saving with mild and comfort condition if the spaces are preheated by automatic control equipment prior to required time.

본 연구는 국내 고층건물 특별피난계단의 부속실에 설치되는 급기가압 제연시스템의 방연 풍속 기류 가화재 발생 시 피난을 위하여 출입문이 개방되었을 경우 거실 방향으로 정상적으로 형성되지 않고 부속실 내부로 역류되는 현상을 개선하기위해 실 모형실험을 통해 출입구 상부로 역류하지 않는 조건을 개발하였다. 부속실 바닥 면적이 $2m^2$와 $4m^2$인 두개의 실물 모형을 제작하여 실험을 실시한 결과, 방연풍속의 기류 특성은 바닥 면적이 $2m^2$인 경우 심하게 출입문 상부로 기류가 역류되었다. 다만, 급기댐퍼의 설치위치가 출입문 맞은편의 경우 날개각도가 45도 상향인 경우는 출입문 상부로는 역 기류 현상은 없었지만 하부로는 일부 역류 되었다. 부속실 면적이 $4m^2$ 인 경우는 출입문에서 거실방향으로 정상적인 기류 분포를 보였다. 부속실 바닥 면적이 작게 설계될 경우에는 성능위주 설계가 될 수 있도록 하여야 한다.
