The Big-Box Efficiency Project
The Big-Box Efficiency Project is evaluating the impacts of installing an integrated suite of precommercial energy efficiency technologies on utility costs, human comfort, operational efficiency, water consumption and maintenance costs. Specifically, the project will assess, install, test, measure and demonstrate the effectiveness of the technologies with the goal of achieving at least a 20% reduction in electricity consumption. The multiyear project spanning Q1 2018-Q1 2022 is a partnership between the California Energy Commission (CEC), Walmart, Center for Sustainable Energy (CSE), Southern California Edison (SCE), and other key partners.
Predicting the technical and financial performance of energy efficiency technology packages is complicated. This is due to a combination of factors, including untested interactive effects and unproven savings benefits of precommercial technologies. The objective is to model and test the technologies to create a blueprint for big-box retail stores across California with similar end‐use and system characteristics.
The Test Site
The technology test site is an existing 24‐year‐old, 134,285-square-foot Walmart Supercenter located in Covina, California, in Southern California Edison’s service territory.
