Parking Garage Applications
Parking garage overall energy conservation and peak load reduction can be maximized by combining time scheduling, dimming on vacancy and daylight harvesting
strategies. Following the example below, an energy saving of 38% is possible in an enclosed parking garage. Perimeter luminaires may be grouped together and programmed
to dim, should natural lighting be available.
