摘　　要：严寒地区供热周期普遍长达半年以上,冬季供热能耗远大于夏季供冷能耗。该地区采取遮阳措施后可以减少太阳辐射,降低夏季制冷能耗,但同时会导致冬季的供热能耗增加。本文探讨了西部严寒地区某公共建筑采用不同遮阳措施后的全年能耗。结果显示:内遮阳可有效降低建筑夏季能耗。采用高反低透的材料,全年能耗增加6%。若内遮阳考虑“人为干预”,可实现夏季节能率25%。The heating cycle in severe cold areas is generally more than half year, and the energy consumption of heating in winter is much higher than that of cooling in summer. Shading measures in this area can reduce solar radiation and cooling energy consumption in summer, but at the same time lead to an increase in heating energy consumption in winter. This paper discusses the annual energy consumption of a public building with different shading measures in the severe cold area of west China. The results show that internal shading can effectively reduce the energy consumption of buildings in summer. The use of high anti-low permeability materials, the annual energy consumption increased by 6%. If "human intervention" is considered in internal shading, the summer energy saving rate can be achieved by 25%.
