The indoor luminous environment of buildings is composed of daylighting and artificial lighting. Through visual effects, non-visual effects and perception, it has a wide impact on people's vision health, emotional cognition, metabolism and immune biorhythms. This study is based on on-site research, investigating three educational buildings and distributing 1154 valid questionnaires. The daylighting environmental score of educational buildings is significantly higher than the artificial lighting environmental score, and key indicators at different time periods include illuminance, correlated color temperature, and color rendering index. In order to improve the classroom luminous environment satisfaction from “neutral” to “satisfactory”, the horizontal illuminance of the desktop should be greater than 500 lx, the color temperature must be greater than 5000 K, and the color rendering index must be greater than 85.
