The California Energy Commission’s Public Interest Energy Research (PIER) Program sponsors the development and demonstration of energy-efficient building technologies. Over the past several years, PIER has developed strategic partnerships with the University of California, California State University, California Community Colleges, and California Department of General Services. These partnerships include a series of demonstration projects coupled with programmatic support to ensure continued deployment of energy-efficient technologies and practices across California. Examples of the latest energy-efficient innovations are described.
Sinisa Novakovic, owner of Mishka’s café in downtown Davis, had two goals for the recent lighting upgrade in his café: create a cozy, inviting atmosphere for customers and save energy. In the main seating area alone he was able to cut his lighting energy use 85% by upgrading to LED lighting. Throughout the rest of the café, energy consumption for lighting has been cut in half, reducing Mishka’s annual energy use by over 10,000 kWh and saving Novakovic nearly $2,000 every year in energy costs. The lighting upgrade will have paid for itself after just eight months.
