Good lighting is one of the most important comfort factors in residential buildings. In creating a restful living space, effects of light, both visual and effects beyond vision play a crucial role. With sun being the most important light source for earth, daylight is considered an important factor for indoor environments, which can benefit occupants’ health as well as (greatly) reducing energy consumption. This study aims to in-vestigate potential daylight exposure for 10 apartments in Sweden, using metrics to quantify both visual effects as well as effects beyond vision, and to understand the correlation between the light situation in the apartments and self-reported well-being metrics collected from the occupants. For this purpose, a quantitative approach was chosen, which included the simulation of daylight conditions for visual effects as well as effects beyond vision. Statistical analysis was utilized to investigate the possible relationship between daylight potential and self-reported well-being of the occupants. The results show variations of light exposure for apartments in dif-ferent seasons. Furthermore, based on the results from t-tests, possible relations between well-being metrics and daylight-exposure-changes during a year were observed.
