基于亮度评价指标下的天然采光舒适度评价研究

Daylight Comfort Research Based on Luminance Assessment

传统采光评价指标主要有静态和动态两类评价体系组成,静态体系以采光系数为代表,动态体系则以全自然采光百分比和有效天然采光照度百分比为代表,这两个评价体系基于以水平面为主传统办公模式可以进行采光性能测试评价,然而现代办公模式下大量使用计算机以后,使用者对于天然采光的要求也将发生了很大改变,该文试图从人眼视觉角度出发,对办公人员基于大量使用计算机屏幕这一背景下进行充分调研及数据搜集,探索出了一套以亮度指标为基准的新型采光舒适度评价方法。

Traditional daylight assessment parameter consists of static and dynamic index. Daylight factor represents static one, while daylight autonomy and useful daylight illuminance represent the other. Yet, these two index are not able to assess daylight quality as modern work pattern has dominanted the offce mode nowadays. Thus, we aim at daylight assessment based on visual angle of occupants and try to explore a new assessment method of daylight quality in terms of luminance parameter.
