Materials
UC Davis chose to affix EverLast Bi-Level Classic Garage fixtures under a photovoltaic (PV) canopy in its south entry parking lot. The 70-watt fixtures have adaptive controls so the lights under the solar-paneled structures automatically switch to low mode when spaces are vacant and full-light output when occupants are detected.

The Retrofit
This retrofit was a response to UC Davis’ requirement to make bi-level lighting a requirement for its PV parking canopies, as stated in the institution’s Campus Standards & Design Guide. The lighting’s control technology saves an estimated 7 percent of the energy harvested through the PV canopy when it is paired with induction light sources. In California, retrofits where induction lamps and bi-level controls replace high-pressure sodium lamps reach about 17 percent, according to the California Lighting Technology Center’s engineering team.
