摘　　要：提高教室中天然光的利用率有利于提高学生绩效、缓解疲劳、节约能源。本文基于重庆高校单侧窗普通教室的实测数据,通过Radiance和Daysim等采光模拟软件对其采光优化设计策略进行研究,提出了一个新型的性能高效、成本可控、维护方便、易于安装的组合式侧窗采光系统,能够明显改善重庆等日光资源匮乏地区的侧窗教室的采光情况。从全年的照度水平和视觉舒适度两方面指标,通过正交实验法和遗传优化算法研究采光系统的采光百叶窗、反光板、穿孔帷幕三个组件的性能影响规律和最佳设计参数,最终可将南向和北向教室近窗区UDI450_2000 lx分别提升142%和102%,远窗区分别提升20%和68%。Increasing the utilization rate of natural light in classroom is conducive to improving student performance,alleviating fatigue,and saving energy.Based on the measured data of ordinary classrooms with single-side windows in Chongqing colleges and universities,this paper uses Radiance and Daysim and other daylighting simulation software to study its lighting optimization design strategy,and proposes a new type of combination with high performance,controllable cost,convenient maintenance and easy installation.The side window daylighting system can significantly improve the daylighting situation of side window classrooms in Chongqing and other areas with insufficient daylight resources.From the annual illuminance level and visual comfort indicators,the orthogonal experiment method and genetic optimization algorithm are used to study the performance influence rules and optimal design parameters of the three components of the daylighting system,including daylighting shutters,reflectors,and perforated curtains.Finally,it can increase the UDI450_2000 lx in the near window area of the south-facing and north-facing classrooms by 142%and 102%,and the far window area by 20%and 68%,respectively.
