本研究介绍了一个人体实验的玻璃类型（颜色和透射率）对参与者的警觉性和情绪，工作表现，并在中国北京的一个全面的办公室自我报告的满意度的影响。在冬季（2017年11月17日至2018年1月15日）测试了七种玻璃系统。研究方法包括照明测量、KSS（Karolinska Sleepiness Scale）嗜睡评估、PANAS（Positive and Negative Affect Schedule）情绪调查、反应时测试（GO/NOGO）和自我报告问卷。主要研究结果如下：昼夜节律刺激（CS）可以作为一个指标的警觉性和情绪在日光照射的工作场所。如果可以实现更高的CS水平（>= 0.3），则玻璃颜色和透射率不会显著影响人的警觉性和困倦。低CS水平（< 0.3）会给居住者带来显著的负面情绪。另一方面，通过增加玻璃窗的视觉透射率和/或降低其色彩饱和度来改善居住者的情绪。自我报告的满意度表明，在视觉性能方面，将优先考虑具有中性颜色和/或较高透射率的玻璃系统。尚不清楚为什么具有4400 K的中等CCT或8100 K的较高CCT的玻璃窗系统可以在反应时间任务中提供更短的响应时间（RT）和更好的工作性能。这将是必要的进行调查的人的表现和光的颜色，特别是在日光条件下。
This study presents a human experiment of effects of glazing types (colour and transmittance) on participants' alertness and mood, working performance, and self-reported satisfaction in a full-scale office in Beijing, China. Seven glazing systems were tested in a winter period (17th Nov 2017-15th Jan 2018). Research methods included lighting measurements, KSS (Karolinska Sleepiness Scale) sleepiness evaluation, PANAS (Positive and Negative Affect Schedule) mood survey, reaction time test (GO/NOGO), and self-reported questionnaires. Key findings are as follows: Circadian Stimulus (CS) can be used as an indicator of alertness and mood in a daylit workspace. If a higher CS level (>= 0.3) can be achieved, glazing colour and transmittance would not significantly affect human's alertness and sleepiness. A low CS level (< 0.3) would bring in significant negative mood to occupants. On the other hand, the improvement of occupants' mood would be achieved through increasing glazing visual transmittance and/or decreasing its colour saturation. Self-reported satisfactions show that a preference will be given to the glazing systems with neutral colour and/or higher transmittance in terms of visual performance. It is unknown why the glazing systems with a medium CCT of 4400 K or a higher CCT of 8100 K can deliver shorter response time (RT) and better working performance in a reaction time task. It would be necessary to carry on investigations into the human performances and light colour, especially under daylighting conditions.
