Empowering Energy Efficiency in Existing Big-Box Retail/Grocery Stores


California Senate Bill 350 aims to achieve a 20 percent reduction in projected statewide building energy use from energy efficiency and conservation measures by 2030. Meeting this aggressive target will require leaders in the commercial building industry to evaluate the performance of holistic energy efficiency technology packages, specifically those that leverage emerging, precommercial energy efficiency measures.

With funding from the California Energy Commission, CSE is partnering with Walmart Inc. and other key partners to assess, install, test, measure and demonstrate the effectiveness of an integrated suite of precommercial energy efficiency technologies in an existing 20‐year‐old, 134,285-square-foot Walmart Supercenter located in Covina, Calif., within Southern California Edison’s service territory.

The project will deploy high-efficiency heating, ventilation, air conditioning, refrigeration and lighting equipment in concert with integrated building-level controls and evaluate the impact of the technologies on utility costs, human comfort, operational efficiency, water consumption and maintenance costs. The objective is to create a blueprint for large buildings across California with similar end‐use and system characteristics.

An additional benefit of this project is its location within a community that qualifies as a “disadvantaged community” (DAC). This gives the project team opportunity to engage with DAC local government officials and residents who visit the site to inform them on energy savings measures and energy-reduction techniques that can be implemented in their community.
