Perhaps most important is ensuring that the light fixtures in each zone receive a consistent amount of daylight at any given time while having consistent light level requirements. ;��A��n��7�S�:9&�Ư(�0gIl- Daylight harvesting, in fact, is favored in LEED projects, not only because of daylight availability, but because energy points are based on exceeding ASHRAE/IES 90.1-2007, and because daylight harvesting is not required by this standard, its energy savings can be captured as LEED energy points. H�\��n�0��y The Dimming WASP is ideal for walk ways, parks, and bike paths to maximize safety and minimize energy consumption. h�bb�a`b``Ń3� ���ţ�AK` Jno These systems enable automatic on/off and dimming, occupancy sensing, and daylight harvesting. Factors such as bi-level and multi-level switching or dimming capability as well as separate circuiting of luminaires in daylighted zones enhance both the usability of a space and energy savings. Daylight harvesting dims electric lights when daylight is available to light the space. The University of California, Davis, has signed co-exclusive license agreements with Watt Stopper/Legrand of Santa Clara, Calif., and Axis Technologies Inc. of Lincoln, Neb., to commercialize inventions that reduce the cost and increase the reliability of daylight harvesting systems. Any system or strategy that relies on daylight to offset electrical lighting needs is known as daylight harvesting or daylighting. Its main purposes are to conserve energy and to provide people with healthy, natural light even when they’re indoors. Hubbell Control Solutions 5.
