Abstract

This article presents a pilot study of effects of glazing on participants’ satisfaction and performance in a full-scale office in Beijing, China. Five glazing systems were tested during a heating season (17 November 2016 to 11 January 2017). Research methods include lighting measurements, subjective assessments, and reaction time test (GO/NOGO). Key findings are given as follows: Daylight illuminances associated with glazing types and times of day play a major role of influencing participants’ visual performances, alertness, physical wellbeing, and relaxation. The glazing type and CCT of daylight did not significantly affect visual responses if a proper daylight illuminance can be achieved. Circadian Stimulus (CS) under daylighting varies in times of day and glazing types, which would affect participants’ alertness and relaxation. Under varying daylight illuminances, some glazing types that can deliver a higher CCT of light would improve participants’ physical comfort and give rise to a longer reaction time.
