摘　　要：穿孔金属板以独特的表现力和成熟的工艺广泛地应用于建筑表皮结构。由于穿孔板的开孔面积不同于普通开窗面积,无法以窗地比作为设计依据,而其采光模拟计算由于缺少相应的依据而耗费大量的时间和人力。通过将穿孔金属板穿孔率与天然光在室内照度建立联系,以M ATLAB为平台编写计算程序,依据室内工作面上控制点的照度要求计算出立面上穿孔金属板的孔隙率,并在Ecotect软件中验证了其计算结果的可靠性,以期为穿孔金属板的设计提供定量化的指导。The perforated metal plate is widely used in building skin with its unique expressive force and mature technology. The window-floor ratio cannot be used as the basis for the perforated metal skin design,because of the different opening area calculation method between common fenestration and perforated plate. Meanwhile,the lighting simulation is a very hard work for buildings with perforated plate skin. The calculation program is compiled based on the relationship between the perforation rate and indoor illumination in MATLAB. Through the illumination of the indoor points,we can calculate rate of holes on the perforated metal,which is a quantitative guidance of the design of perforated metal plate.
