Abstract

The recent climate change is exacerbating the external thermal environment and increasing the amount of energy used in building. Energy Plus was used to evaluate low energy technology performance of buildings responding to climate change. The test types of basic building(control) and evaporative mist system + basic building(EMS), and the analysis results of each type are compared. Energy performance evaluation result, Cooling peak load were EMS reduction compared to control is about 9%. Annual cooling load per unit area were EMS reduction compared to control is about 17%. Annual energy use per unit area were EMS reduction compared to control is about 10%. Therefore, the effect of the evaporative cooling system is considered to be good through energy reduction technology of building, according to the amount and distance of the evaporative mist system in the future research on building energy performance evaluation should be carried out.

최근 기후변화로 인한 외부 열환경이 악화되고 있으며, 이로인한 건축물에너지사용량이 상승하고 있다. 기후변화 대응형 건축물 저에너지 기술 성능평가를 위하여 Energy Plus를 활용하였다. 실험군 유형은 기본건축물(Control)과 기화냉각시스템(EMS)이며, 유형별 분석결과를 비교하였다. 에너지성능평가결과 냉방피크부하는 Control 대비 EMS에서 약 9% 이상 저감률을 보였다. 단위면적당 연간 냉방부하는 Control 대비 EMS에서 약 17% 이상 저감률을 나타내었다. 단위면적당 연간 에너지사용량은 Control 대비 EMS에서 약 10% 이상 저감률을 보였다. 따라서 건축물 에너지저감기술로 기화냉각시스템의 효과는 양호한 것으로 판단되었으며, 향후 기화냉각시스템의 분사량 및 이격거리에 따른 건축물에너지성능평가 연구가 진행되어야 할 것이다.
