Daylighting is the practice of placing windows, skylights, other openings, and reflective surfaces so that direct or indirect sunlight can provide effective internal lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use.
Daylighting can refer to: Daylighting (architecture), use of windows for indirect lighting; Daylighting (intersections), improving road visibility at intersections; Daylighting (streams), restoration of a previously buried watercourse; Daylighting (tunnels), opening a transportation tunnel

[6] [7] Daylighting reduces collisions by removing obstructions that prevent drivers from seeing other cars, pedestrians, bicyclists, and other road users. The National Association of City Transportation Officials recommends daylighting by preventing cars from parking within 20–25 feet (6.1–7.6 m) of an intersection. [ 8 ]
Architectural lighting designer is a stand-alone profession that sits alongside the professions of architecture, interior design, landscape architecture and electrical engineering. [ 23 ] One of the earliest proponents of architectural lighting design was Richard Kelly who established his practice in 1935.
Compared to traditional or conventional buildings, tension fabric buildings may have lower operational costs due to the daylight that comes through the fabric roof when light-coloured fabrics are used. This natural lighting process is known as daylighting and can improve both energy use and life-cycle costs, as well as occupant health. [1] [2]
Daylight harvesting systems are typically designed to maintain a minimum recommended light level. [1] This light level will vary according to the needs and use of the space; for example, the commonly recommended light level for offices is 500 Lux (or around 50 foot-candles) on the desktop.
Climate based daylight modelling (CBDM) also known as dynamic daylight metrics is a calculation methodology first developed in the late 1990s to assess daylight quality and quantity.
