Bi-level Smart Parking Garage Fixture |
Many parking garage structures in commercial and institutional facilities are currently illuminated with High Pressure Sodium (HPS) and Metal Halide (MH) ceiling mounted fixtures. The nature for this type of lighting application requires illumination throughout the entire day. However, occupancy patterns are ignored and thus entire garages, or areas of garages, are often lit and vacant for long periods throughout the day/night.
In order to develop a solution that addresses this savings opportunity, the California Energy Commission's PIER Program funded the development and demonstration of a garage fixture that integrates state of the art LED sources and occupancy-based dimming controls. The high optical efficiency and light quality delivered by the LED sources requires less energy demand than typical HID sources. The bi-level controls provide additional energy savings that is directly proportional to automatic and pedestrian traffic patterns.
