Daylighting
Daylighting uses natural daylight as a substitute for electrical lighting. While it will likely be counterproductive to eliminate electrical lighting completely, the best proven strategy is to employ layers of light - using daylight for basic ambient light levels while providing occupants with additional lighting options to meet their needs.
An effective daylighting strategy appropriately illuminates the building space without subjecting occupants to glare or major variations in light levels, which can impact comfort and productivity.
In order to provide equitable access to daylight ensure the space is optimized to disperse daylight well. Locate private offices toward the core of the space and specify low workstation panels. Use glass walls and light-colored surfaces on walls and desks to disperse daylight throughout the space. In all daylighting strategies, it is important to consider glare and to take steps to minimize it. Find more strategies below:
