The Facilities Division and Sustainable Berkeley Lab are partnering to optimize energy use in buildings across the site. Many of our buildings run at close to the same level 24 hours per day. We are working to better match the operation of building heating/cooling and lighting systems to what occupants really need and to track performance over time. In January, we deployed the program as a pilot in Building 15. Based on this experience, we plan to expand the program next to Building 67, Building 74, and the new buildings coming online this year: GPL, SERC, and CRT.
