This four-year, $3.6M project funded by the California Energy Commission will target one of the “final frontiers” in California’s goal towards a Zero Net Energy (ZNE) future: grocery stores. The project will design and retrofit an existing Whole Foods Market in San Francisco, CA into the world’s first zero net energy (ZNE) grocery store. As part of the project we will be targeting new products and technologies to bring into our design with the goal to “design for scale.” Project partners include Whole Foods Market, Arup, Lawrence Berkeley National Laboratory and the City of San Francisco Department of Environment.
