Case Study: Tustin Centre achieves over 6% energy savings with Gridium's Snapmeter & Billcast

TOBY Award Winner Tustin Centre Saves More than 6%

Tustin Centre is a 205,000 sq ft Class A office tower in Orange County, owned and managed by CBRE, and recognized with LEED‑Gold certification and a TOBY award. Despite recent capital upgrades to improve tenant experience and operational efficiency, the property faced rising utility bills—more than 14% higher in nearly every month—driven by unexplained weekday energy drift and peak demand spikes.

Gridium deployed Snapmeter and Billcast to automatically analyze 15‑minute interval and monthly bill data (no onsite hardware or BMS integration required), sending weekly alerts and variance reports to operations. The analytics pinpointed persistent weekday demand peaks and simultaneous heating/cooling; after the engineering team corrected the issues, Tustin Centre reduced daytime energy use by over 6% and achieved consistent monthly energy savings.
