California AB802 – Building Benchmarking Program

About AB802

Starting in 2018, the California Energy Commission (CEC) requires benchmarking of large commercial and multifamily buildings, due annually on June 1st. The intent of AB802 is to improve the energy efficiency of large buildings statewide by allowing building owners to make informed decisions based on their buildings performance. Buildings not in compliance may be subject to non-compliance fees.

What is Benchmarking?

Benchmarking compares the energy use of a building to other buildings of similar size and use type. The result of benchmarking is an ENERGY STAR score for 0 to 100. Benchmarking is useful for determining the baseine efficiency of a  building and tracking energy efficiency initiatives.

Who is Required to Benchmark?

All commercial buildings greater than 50,000 square feet and residential buildings greater than 50,000 square feet and 17 or more utility accounts are required to comply with the annual benchmark.
