摘　　要：水平遮阳板不同遮阳角度对太阳辐射的遮阳效果会产生不同影响。为了使尺寸与材料固定的建筑外遮阳在太阳高度角和方位角变化时能够满足遮阳需求在不同季节的变化,需要采用遮阳角度可随之进行调节的外遮阳设计,以满足对遮阳效果的要求。以南京地区典型气象年气象为依据,对该地区住宅建筑南向外墙遮阳板不同遮阳角度下的遮阳系数进行建模分析,从而得出当地南向水平外遮阳的遮阳效果在不同季节及全天不同时刻的变化趋势。Different shading angles of horizontal external shading would bring variable influence on shading effect for solar radiation. The building horizontal external shading angles were designed with the fixed size and material to meet different requirement of shading effect in seasons. The building horizontal external shading angles were designed with the fixed size and material to meet different requirement of shading effect in seasons. It was analyzed with mathematical model of different angles on the basis of the typical meteorological year weather in Nanjing area, from where the variation tendency of shading angle could be obtained for different season and time period.
