A STUDY ON THE EVALUATION METHODS OF INDOOR LIGHT ENVIRONMENT FOR OCCUPANT COMFORT AND WELL-BEING

Abstract

Since the COVID-19 pandemic, awareness of the importance of the indoor envi-ronment has increased. The indoor light environment is crucial because it impacts the energy consumption of buildings and affects human health and biorhythms as people spend most of their time indoors. Previous studies have concluded that the indoor light environment is essential to human health. However, it is not sufficient to analyze and evaluate the indoor light environment related to occupants' health in the context of building design. Therefore, this study aims to review and propose an indoor light environment evaluation methodology for human well-being using quantitative and qualitative evaluations of light, health, and environment. This study presents guidelines for evaluating buildings' indoor light environment for sustainability and well-being. Additionally, it provides an overall checklist of the indoor light environment evaluation process in Conceptualization, Light Environment Identification, Questionnaire, Environment Analysis, Comparison, and Conclusion. The evaluation checklist established through the results of this study could help establish a research methodology for the indoor light environment for human well-being, and apply it to evaluate indoor light environments for residents' comfort and well-being.
