摘　　要：以南京市典型年逐时气象参数为基础、南墙外窗为对象,基于房间反应系数法,利用MATLAB编程分析其动态负荷变化,研究平开式飘窗在使用不同窗体和玻璃材料下,飘窗挑板宽度从0.2～1.0m时飘窗带来的全年能耗。结果表明,南墙飘窗的全年能耗随着挑板宽度的增加而加大,但如果使用节能性好的窗体和玻璃可以大大降低其能耗,根据目前夏热冬冷地区建筑能耗节能50%的要求,PVC平开中空玻璃飘窗的挑板宽度不超过0.3m时较为节能,而铝塑复合平开Low-E玻璃飘窗的挑板宽度不超过0.5m时较为节能。According to the hourly typical meteorological year data in Nanjing,based on dynamic thermal response eoeffieient method of walls, MATLAB is used to analyze its dynamical load change,as well as to study the annual energy consumption of side hung bay window, which is made of different forms and glass materials and whose cantilever slab width is from 0.2 m to 1.0 m. The result shows that the annual energy consumption of south bay window will be increased with the eantilever slab width inereasing, but it could be reduced greatly if the bay window is made of better efficiency energy-saving forms and glass material. According to the request of energy saving 50% of building in hot summer and cold winter area at present, the PVC side hung insulating glass bay window with cantilever slab width less than 0.3 m has better energy saving effect, and aluminum-plastic composite side hung Low-E glass bay window with cantilever slab width less than 0.5 m has better energy saving eft）ect .
