jailcd2024041: Review on Workspace`s Lighting Performance based on Circadian Lighting Characteristic

Abstract

This research focuses on reviewing the workspace at the University of Kitakyushu to determine whether it aligns with circadian lighting characteristics. Circadian lighting, designed to mimic the natural variations in light throughout the day, has emerged as a promising intervention to enhance the overall well-being of building occupants. The investigation begins by reviewing the current literature on circadian rhythms and their connection to human health and performance. It then delves into the technical aspects of circadian lighting systems, considering factors such as light intensity, colour temperature, and the angle of the light source. This research employs a quantitative method approach by measurement the distribution light, timing of light exposure, light correlated colour temperature (CCT), and collecting the feedback of workplace users. Preliminary findings suggest a significant correlation between exposure to circadian lighting and improvements in working performance, mood, and cognitive performance. The implications of this research extend beyond mood, health and performance to broader societal benefits, including improvements in overall workplace productivity. By shedding light on the impact of circadian lighting in buildings, this research contributes valuable insights to the ongoing discourse on creating healthier and more sustainable built environments.
