성능진단 데이터로 보정된 모델을 이용한 기존건축물의 에너지시뮬레이션 기법

Abstract

Abstract This paper represents a method of existing building energy simulation using energy audit data. Energy audit mustbe carried out for reasonable analysis, because characteristics of existing buildings such as efficiency of fan, pump, flow rate, pressure, COP and operating schedule could be changed during the building operation. These building characteristicsshould be measured to estimate actual energy consumption of the existing building. In this study, we conducted energy audit and calculated energy savings for a 7-stories building as a case-study. The energy audit data were used to calibrate the building model of EnergyPlus simulation. Baseline model validated according to M&V guideline index. As a result,building characteristics are significant parameters making a big impact on energy savings in existing buildings.
