摘　　要：基于多区域通风模型和建筑能耗耦合分析法,结合2014年南京地区室外空气质量监测数据,对不同自然通风策略下的住宅建筑空调能耗进行了数值模拟。结果表明,室外空气污染导致自然通风有效的利用时间减少,建筑全年空调能耗上升,4~9月自然通风带来的节能量下降了31.7%。Based on the multi-zone airflow model coupled the dynamic energy consumption analysis,numerical simulations were carried out to study the energy consumption of a residential building under different outdoor conditions(combination of AQI and meteorological data).The results show that due to outdoor air pollution,the natural ventilation available time in Nanjing decreased in 2014 while the annual energy consumption of building increased.The energy saving potential of natural ventilation decreased by31.7% during April to September.
