摘　　要：遮阳措施对于降低建筑能耗意义重大。针对成都地区1栋典型多层居住建筑,分别对水平活动百叶遮阳和垂直绿化遮阳这两种不同形式下的建筑能耗进行了计算,深入分析了节能特点,根据不同朝向对比分析了节能效果。结果表明:垂直绿化遮阳综合节能率是同等条件下水平活动百叶遮阳节能率的2~3倍,是更适用于成都地区的外遮阳设计;4个方向均设遮阳的综合节能效果优于单向设置遮阳,单向设置遮阳中南向设置遮阳最优;绿化遮阳较广的遮阳面积及其对周围气候环境的动态响应机制更利于建筑节能。Shading measures for reducing construction energy consumption is of great significance.In view of a typical multi-storey residential building in Chengdu,building energy consumption was calculated on the level of horizontal movable louver shading and vertical green shading of the two different forms respectively,in-depth analysis of such characteristics,according to the comparative analysis of energy saving effect in different directions.The results show that the vertical green shading comprehensive energy saving rate is 2~3 times the level of horizontal movable louver shading under the same conditions.It is more suitable for the design of Chengdu area.The 4 directions are equipped with comprehensive energy saving effect better than single set sun shading,shading in the south set one-way shading optimal.Green shading area sunshade wide and the climate around the dynamic response the mechanism are more conducive to building energy saving.
