Benchmarking Resources
Understand Benchmarking
The California Building Performance Resources Hub offers several pathways for building owners and managers to learn about and complete building benchmarking, a requirement for most large buildings in California and one of the first steps in improving your building’s performance.
Benchmarking 101
Start with our overview guide to understand what benchmarking is and why it is important. Identify whether benchmarking is required for your building on our California policy page.
Check out the benchmarking page in our Strategic Decarbonization Guide to learn how to Benchmark on your own, or with third-party support.
