摘要

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.
