This study aims to analyze the current use of natural daylighting in contemporary museums and propose effective and safety daylighting design criteria by examining daylighting types and measuring illuminance variations by space. Case studies of both domestic and international museums were conducted to investigate daylighting strategies and architectural features. Additionally, in two selected domestic museums, illuminance (lux) was measured at 11:00 AM, 1:00 PM, and 4:00 PM on a clear day in January 2025, and daylighting types were classified. The results show that exhibition spaces generally restrict direct daylight to preserve artworks and ensure visual comfort, predominantly using indirect or diffused daylight through louvers, translucent glass, and blackout systems. In contrast, non-exhibition spaces such as lobbies, corridors, and lounges actively incorporate large windows, skylights, and courtyards, with average illuminance levels often exceeding 500–2000 lux. These tendencies are closely linked to exhibit characteristics and conservation requirements, particularly with the growing prevalence of video and installation art. The study suggests that future exhibition facilities designs should adopt differentiated daylighting strategies based on space functions, incorporating advanced daylight control technologies such as adjustable louvers, motorized blinds, and fiber optic daylighting.
