Optimized design of external shading device via parametric design approach

Lihua Zhao, Jie Shen, Jun Guo, Yang Dong

Abstract: In this paper, parametric design approach is used to optimize the external shading device design, which take examples of horizontal shading devices and horizontal louver shading devices on south faced of buildings in Guangzhou, Shanghai and Beijing. The optimize goal of whole year shading effect is “Shading in summer and solar in winter, both as much as possible at the same time”. In the first part of this paper, the external shading devices are optimized integrally and systematically. In the second part, the calculated data are analysed and organized, and some simple design rules for external shading devices have been summarized: tilt up 30° louver shading device is the best of four kinds devices involved in this paper, and a shading device can get better effect as latitude rise up.
