摘要
为了更有效、更快速、更精确地分析复合开窗系统(Complex Fenestration Systems,CFS)的天然采光室内光环境,本文介绍了利用双向分散分布模型(Bidirectional Scattering Distribution Function,BSDF)来模拟计算室内光环境的方法,并分析了针对不同复合开窗系统类型获得双向分散分布模型数据的3种方式。以最为复杂的微棱镜结构日光重定向系统为例,通过案例实际照度测量与模拟数据的对照分析了双向分散分布模型针对复合开窗系统天然采光模拟方法的可靠性,以及微棱镜结构日光重定向系统对天然采光室内照度均匀度与光环境质量的提升。
For more effectively, quickly and precisely analyzing the daylighting luminous environment with complex fenestration systems(CFS), a method utilizing Bidirectional Scattering Distribution Function(BSDF) is introduced along with the introduction of three measures to generate BSDF data for different complex fenestration systems. Measured illuminance distribution in a case study with micro structured prismatic film is compared with the simulation data to verify the effectiveness of BSDF analysis method. Meanwhile, the advantages of prismatic film for improving indoor daylighting illuminance uniformity and luminance environment are analyzed as well.
