Energy use in buildings consumes nearly 70% of California's electricity. The Center for Sustainable led a multiyear energy efficiency project at three San Diego libraries to create a blueprint for helping municipal and small commercial buildings reach the goal of zero net energy (ZNE).
In partnership with the California Energy Commission and the city of San Diego, CSE’s project team evaluated and tested the benefits of lighting and HVAC upgrades and automated controls. Learn how demand-side energy management helped maximize energy savings, reduce emissions and cut costs.
