RTS-SAREK을 이용한 사무용 건물의 나이트 퍼지 성능 평가

It is important issue to reduce the import energy to save the operating cost of office building. To solve the problem, there is a method of night purge that can decrease cooling load using natural ventilation at night. The objective of this study was to provide effectiveness of night purge by measuring cooling load variation. In this study, RTS-SAREK appling RTS method is used. As a result, it showed that the value of building cooling load applying the night purge is reduced by up to 113% than before applying night purge. Through this, it is expected that night purge method activation in choosing outdoor air conditioning system in building design.
