摘　　要：给出了节能建筑供暖临界温度的计算方法 ,讨论了日照、建筑节能设计的影响 ,说明日照率低的地区供暖临界温度偏高 ,日照率高的地区增大南向窗墙比有利于建筑节能。Presents the calculating method of outdoor critical air temperature for energy-saving buildings, discusses the effects of sunshine and energy efficiency design. The results show that the outdoor critical air temperature for energy-saving building in low sunshine ratio area is higher than that in high sunshine ratio area where increasing south window-wall ratio can get more solar energy.

关 键 词：节能建筑 冬季 供暖 临界温度 日照率
