用CAD进行准确快速的建筑日影分析

Accurate and Quick Method of Sun Shadow Analysis in Building Design with CAD

传统的建筑日影分析方法因繁琐复杂而难以在设计工作中普及应用,笔者发现借助现代CAD的先进技术,可以直观方便地绘制太阳轨迹,获取日照方向,进而准确快速地分析日影,整个过程原理明确、方法简单,很适合向广大设计人员推广。

It is difficult for the traditional measure of architecture sun shadow analysis to be spread and applied in design because of its fussiness and complexity. The author found, with help of CAD, that we could draw sun orbit to get direction of sunlight visually and expediently, and analyze sun shadow of building accurately and quickly. The theory is definitude and the operation is simple in whole process. It is suitable to be extended widely to the designer.
