Daylighting is the practice of using natural sunlight as much as possible to provide internal building lighting. The intent is to save on electricity for lighting and heating a building. Windows, skylights, and light-colored ceilings work together to allow sunlight into a room and disperse it as evenly as possible.
The windows are either south or north facing to avoid the extreme glare of the rising and setting sun. Reflective surfaces and daylight redirection devices take sunlight beams that would otherwise cause glare, and redirect them to the ceiling where the light is reflected and uniformly spread out in the room.
Because sunlight availability changes throughout the day, daylighting is integrated with artificial lighting so that as the interior natural sunlight increases, the interior artificial lighting dims to keep the overall brightness constant. Likewise, when the sunlight decreases, the artificial lighting brightens. This is accomplished by using light sensors and dimming/brightening controls. …show more content…
When the sunlight dims, the LEDs do a good job of preserving the room's sunlit ambiance. Like natural sunlight, LED lighting also acts as a stimulant to the human circadian system. This increases alertness, concentration, and focus, all of which increase worker productivity. The lighting also increases sales in retail environments because colors are more vivid, which increases the attractiveness of goods and
