Daylighting is essential for human health and well-being. As urban areas become more densely built, access to daylight is increasingly restricted. In some locations, the close proximity of buildings raises privacy concerns, leading occupants to use blinds or curtains that block daylight. Additionally, curtains or blinds are sometimes used to control direct sunlight and glare. Other factors, such as occupants' sensitivity to light and social norms, also play a role. Daily behavior patterns, such as napping in the afternoon, can further reduce daylight access. Limited daylight often results in a higher reliance on artificial lighting indoors, and in some cases, insufficient daylight forces occupants to depend entirely on artificial light. It is important to analyze the collected data from residential buildings, identify the gaps, and explore potential design interventions to enhance daylight access, ensuring more comfortable and healthier living conditions for the occupants.
