건물 내 열/공기환경 통합시뮬레이션 기법에 관한 연구

Indoor Air Quality (IAQ) has become one of significant issues in building design process in Korea. To evaluate the performance of IAQ-dedicated measures or the effectiveness of ventilation strategy, various modelling technologies are exploited including CFD simulation and air flow network. Since CFD requires significant calculation time and hardware resources, inappropriate application of the technique is likely to lead to time wasting and sometimes incorrect results. To gain the accurate simulation results, state-of-art, effective modeling strategy and appropriate tools should be identified and applied. This paper presents an integrated modelling technique of building thermal, airflow network and CFD. The applicability of the method is also discussed with case studies.
