Abstract
Light in the office space is an essential environmental element that has a tremendous impact on the physiology and psychology of the occupants. In this study, the effects of lighting illuminance and color temperature on occupant’s mood were investigated. Two illuminance levels, i.e., 300 lx and 2000 lx, and two color temperatures, i.e., 3000 and 6000 K, were set, creating four experimental conditions. A total of 24 subjects participated in the experiment. Light perception and mood were assessed by questionnaires including PANAS affect scale. The results indicate that positive affect increased under 2000 lx 6000 K and 300 lx 3000 K light. No significant difference in the negative affect was observed. These findings could serve as a predictor of the cognitive performance of employees and would help optimize the working environment according to the specific needs of these workers.
