Daylight harvesting systems use daylight to offset the amount of electric lighting needed to properly light a space, in order to reduce energy consumption. This is accomplished using lighting control systems that are able to dim or switch electric lighting in response to changing daylight availability.
At night, ORNL HSL uses variable-intensity fluorescent lighting electronic control ballasts. As the sunlight gradually decreases at sunset, the fluorescent fixture is gradually turned up to give a near-constant level of interior lighting from daylight until after it becomes dark outside. HSL may soon become an option for commercial interior ...
Daylighting is the controlled admission of natural light, direct sunlight, and diffused skylight into a building to reduce electric lighting and save energy. A daylighting system comprises of not just daylight apertures, such as skylights and windows, but is coupled with a daylight-responsive lighting control system. [9]
The device can reproduce direct light at any location on Earth. [4] After the 2000s, Prof. Norbert Lechner, an architect, LEED AP and an expert in energy responsive architecture has invented a manual Sun Emulator Heliodon. [5] He invented heliodons which were much easier to evaluate daylight simulation than the previous models. [5]
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. It is used by Building Design engineers and architects to predict luminance and/or illuminance within buildings using standardised sun and sky condition climate ...
Daylight redirecting film (DRF) is a thin, flexible plastic film which can be applied to a window to refract or reflect incoming light upwards so that the deeper parts of the room are lit more evenly. It can be used as a substitute for opaque blinds. [2] It is a form of prism lighting.
