Overview
The Civic Center’s Earl Warren Building (1922) and Hiram M. Johnson State Office Building (1998) presented unique challenges: historic preservation requirements, aging infrastructure, and a nonfunctional proprietary controls system. As home to the California Supreme Court and multiple state offices, all upgrades had to be completed after hours to maintain secure, uninterrupted operations. The State required whole-building (Option C) M&V to verify actual savings at the utility meter level.
Solutions
CEG designed and implemented 11 ECMs to cut energy and water usage, renew infrastructure, and reduce costs. Using 315 sensors/loggers with cellular modems, CEG analyzed 16.1M data points to create custom control strategies and implement demand response load shifting. A new EMS enabled advanced control and trending, simplifying Option C M&V. Measures included LED retrofits, upgraded economizer & pressurization controls, hot water pump recommissioning, cooling tower control upgrades, and advanced lighting occupancy controls.
Results
The project delivers $700K in verified annual savings and reduces energy use by 16,139 MMBtu — a 38% reduction across the campus. Whole-building Option C M&V confirmed that measured savings exceeded the guarantee by $180K (33%). The new open-source BAS eliminated dependence on proprietary systems, improving flexibility and long-term resilience.
