建筑侧面采光评估方法及优化研究

随着人们对室内环境及舒适性的提高,采光的好坏直接影响了室内环境品质。本文基于《建筑采光设计标准》GB 50033-2013的有关要求,对Lynes提出的平均采光系数法及Radiance为内核的PKPM采光模拟软件的模拟法,针对不同窗地面积比、不同有效进深时分别对两种方法进行评估。当窗地面积比、有效进深相同时,通过改变层高、房间尺寸、窗台高,使用两种方法评估其平均采光系数,得到优化方案。

Evaluation Method and Optimization of Side Lighting for Buildings

With the improvement of indoor environment and comfort, lighting directly affects the quality of indoor environment. Based on GB 50033-2013 Building Lighting Design Standard, this paper evaluates the average daylighting coefficient method proposed by Lynes and the simulation method of PKPM lighting simulation software with Radiance as the core. When the area ratio and effective depth of windows are different, the two methods are evaluated. When the area ratio and effective depth of windows are the same, the average daylighting coefficient is evaluated by changing the floor height, room size and windowsill height, and the optimization plan is obtained.
