(civil engineering)
To light an area with daylight.

Daylighting

Using natural light in an interior space to substitute for artificial light. Daylighting is considered a sustainable building strategy in that it can reduce reliance on artificial light and reduce energy use in the process, and when well designed, it contributes to occupant comfort and performance. Common daylighting strategies include the proper orientation and placement of windows, use of light wells, light shafts or tubes, skylights, clerestory windows, light shelves, reflective surfaces, and shading, and the use of interior glazing to allow light into adjacent spaces. South-facing windows are most advantageous for daylighting and for moderating seasonal temperatures. They allow the most winter sunlight into the home but little direct sun during the summer.

daylighting

Lighting of the interior of a building by natural means; for example, by windows or skylights.

The key building variables affecting daylighting are building area and orientations, glass type, window areas, shading and external obstruction [5].
The first Solatube Daylighting System was sold in 1991 and millions have been installed since.
The cost of the daylight sensor is generally the same cost as the occupancy sensor, and proper daylighting often provides a similar percentage energy reduction, but a considerably larger percentage peak power reduction than occupancy sensing.
Many daylighting techniques are site-specific, so the amount of fenestration, window to wall ratios (by orientation), skylights or roof monitors, and fixed shading devices can all be adjusted to optimize the use of available daylight.
The daylighting model consists of the calculation of incident and transmitted illuminance using the Perez model (Perez et al.
When the project team discusses daylighting a building and the design strategies include the use of light shelves, the team has to look at it from a holistic, integrated perspective.
northern San Diego County) in the United States, is the exclusive licensee and marketer of Tubular Daylighting Devices (TDDs) in Europe, Latin America, Central Asia and The Middle East.
Few technologies offer the level of both human and environmental benefits that daylighting does, yet its market share remains only a sliver of what it could be.
Office Daylighting Potential, a study for the California Energy Commission, found that improving interior reflectance was one of the most consistent variables providing energy savings.
Other building standards, including IECC and Title 24, are following suit by including similar daylighting requirements in their updated recommendations.
