이중창 시스템 적용성 평가를 위한 시뮬레이션 모델링 기초 연구

As double facade systems are adopted for energy saving in curtain wall buildings, their performance are often evaluated with detailed computer simulation. the results derived from inappropriate models are likely to lead to wrong decision. when applying simulation models, preliminary tests should be made to define appropriate model. In this study, a the energy performance of a proposed double window system was tested with ESP-r simulation. To implement this test, different scaled air-flow network models were produced, and their results were compared. It was identified that the energy performance of the proposed double window systems varies depending on the modelling strategies. The error rate between different scaled models is about 15%. It is important to consider appropriate modelling strategy compromising efficiency with accuracy.
