About Lawrence Berkeley National Laboratory

Managed by the University of California, Lawrence Berkeley National Laboratory conducts unclassified research across a wide range of scientific disciplines. Berkeley Lab's energy efficiency innovations have contributed more than $484B to the U.S. economy and we are delighted to partner with small businesses to solve some of their most pressing challenges across the areas of buildings, bio-energy, advanced manufacturing, vehicles, fuel cells and geothermal research and technologies. Strategically located in the Bay Area ecosystem of innovation, Berkeley Lab creates 12,000 jobs and contributed $1.6B to the US economy annually.

Capabilities

Berkeley Lab’s history of buildings research and development reaches back to its pioneering building energy efficiency work, and includes now-commonplace inventions such as electronic ballasts and low-e window coatings. Today, Berkeley Lab’s vision encompasses dynamic and integrated buildings systems and the ability to test and evaluate that integration in its FLEXLAB facility. This whole-building, multi-system approach strives to fundamentally fuel a revolution in the built environment, to achieve a 50% energy reduction in buildings by 2025.

Berkeley Lab works with utilities, owners, operators, designers, contractors, and manufacturers to achieve these goals and speed market transformation through the advancement of the following:

  • Measurement, Data-Driven and Simulation Modeling and Optimization
  • Data Management, Owner and Operator Decision Tools, Information Systems and Analytics
  • Integrated System Design and Dynamic Control Solutions
  • Interoperability and Building Integration with the Grid and Urban Systems
  • Real-Time Energy Management, Feedback, and Performance Visibility
