摘　　要：针对重庆地区夏季太阳辐射强,且用户在外窗采用各种遮阳形式但遮阳效果却不理想的问题,建立能耗计算模型进行模拟分析。采用以DOE-2为内核的建筑能耗计算模型工具,分析了重庆地区4种典型居住建筑中遮阳系数与能耗的关系,着重分析了东、南、西、北朝向上各遮阳系数与建筑能耗的关系。经分析得出:各建筑类型四朝向上遮阳系数与建筑能耗呈线性关系,且重庆地区不可忽略北向遮阳对采暖能耗的影响,在夏季应特别注意东、西向遮阳。The summer solar radiation in Chongqing area is very strong, and a variety of window shadmg Jorms were artopted. However, good shading effect was not accepted. Based on the above, energy consumption model was established. The building energy consumption analy- sis tool which based on DOE-2 was applied, and the relationship between energy consumption and the shading coefficient of four typical resident buildings were analyzed, as well as the relationship in the East, South, West and North. The results show that a linear relationship between them was gained in the four directions, and the impact of north-shading on the heating energy consumption can be not neglected in Chongqing area. In addition, the east and west window shading should be especially paid attention to in summer of Chongqing area.
