    Lighting strongly influences indoor well-being, yet existing metrics like "Daylight Autonomy" and "Annual Solar Exposure" overlook circadian light. Research highlights circadian light's significant impact on human performance, creating a need to explore spatial factors affecting its distribution. This study examines the influence of surface reflectance, proximity to windows, windows' optical properties, and gaze direction on circadian light. Using the Lark Plugin for Grasshopper, simulations were conducted in a box-model room with ten glazing systems varying in visible transmittance. The results show that windows with a visible transmittance below 0.3 fail to provide adequate circadian light unless the gaze is perpendicular. Among surface reflectance factors, wall reflectance proved more critical than ceiling reflectance in optimizing circadian light exposure.
