LED Upgrade Saves Money 

Customer: California Public Utilities Commission (CPUC)


Wesco Energy Solutions partnered with the State of California, Department of General Services, Pacific Gas and Electric Company’s Sustainable Solutions Turnkey (SST) team, and California Public Utilities Commission (CPUC) to complete a facility wide lighting upgrade at the CPUC headquarters building. The project included updating a parking garage and interior office spaces.

Our team conducted a facility wide audit that determined a total of 4,763 fixtures to be updated to the appropriate LED fixtures. We leveraged key manufacturers to install the best products throughout the facility. A key focus for the upgrade was to better control the facility. Our team provided a fully designed and commissioned Title 24 compliant advanced control system for all interior and exterior lighting measures that can be controlled remotely. The wireless control system features time-based scheduling, occupancy control, daylight harvesting, manual override switching, and top end tuning/dimming. Wesco Energy Solutions conducted all necessary acceptance testing per CALCTP-ATT guidelines and filed forms appropriately.

The garage presented some safety issues caused by several dark areas throughout the structure, which were easily addressed by updating all the lighting to LED. The design team used a photometric lighting layout to establish what kind of light levels would be achieved post retrofit to best address these dark areas. This approach allowed the light levels and distribution to be dramatically improved.
