摘　　要：分析了传统民居屋檐、檐廊以及建筑布局对南向外窗的遮阳作用。通过对典型建筑实例计算后发现:传统民居的屋檐的遮阳效果随其挑出长度而增大,当挑出长度为0.5m时,外窗平均综合遮阳系数不大于0.5;当挑出长度为1.5m而成为檐廊时,综合遮阳系数不大于0.35;东、西侧建筑分别在午前和午后对与其正交相邻的外窗具有很好的遮阳效果,两者距离越近,遮阳作用越明显;南侧对面建筑对其北侧建筑外窗的遮阳作用不大。A method to calculate external and overall shading coefficient of southern window of traditional dwelling was put forward after analyzing the shadow area of window brought by eave, porch and other buildings. A typical traditional dwelling was studied using this method. The results show that shading effect of eave is improved when outstretch length of the eave increases, the ovemU shading coefficient is less than 0.5 when eave outstretches by 0.5m, and less than 0.35 when it outstretches 1.5m as a porch; other adjacent side buildings located at east and west present favorable shading effect before and after noon, respectively, and the window is more close to side building, the shading effect is better; nevertheless, there is little shading effect by the parallel south building.
