Research on the layout of external shading components and the design of microstructure in combined-facade of subtropical architecture

One key measure to increase building energy efficiency in subtropical area is the external shading in facade. This article intensify the analysis of the external shading component design. By discussing the layout of external shading components and the microstructure in combined-facade of subtropical building, anatomizing the facade of some completed buildings, it explores new possibilities of shading design. It researches by software simulation on the block of solar radiation and indoor illumination effects, optimally selects the analysis model, and determines the specific application in building design. Reasonable layout of the shading components and the perforated structure enrich the possibilities which the architectural surface space can have in terms of building heat insulation and design aesthetic.
