Program Overview

Assembly Bill 802 (Williams, 2015) directed the California Energy Commission to create a statewide building energy use benchmarking and public disclosure program for buildings larger than 50,000 square feet. The Commission's regulations require building owners to report building characteristic information and energy use data to the Commission by June 1 annually, beginning in 2018 for buildings with no residential utility accounts, and in 2019 for buildings with 17 or more residential utility accounts. Building owners will complete their reporting using ENERGY STAR Portfolio Manager, a free online tool provided by the United States Environmental Protection Agency.

Assembly Bill 802 also requires, effective January 1, 2017, that energy utilities provide building-level energy use data to building owners, owners' agents, and operators upon request for buildings with no residential utility accounts and for buildings with five or more utility accounts.

The Energy Commission will publicly disclose some of the reported information beginning in 2019 for buildings with no residential utility accounts, and 2020 for buildings with residential utility accounts.

The Importance of Benchmarking and Public Disclosure

Publicly disclosing the performance of buildings will allow building owners and tenants to make better informed purchasing and leasing decisions, and the general public to better understand the buildings in which they live and work. Portfolio Manager, a nationally recognized program, will allow comparison with similar buildings across the state and the country.

Local Benchmarking and Public Disclosure Ordinances

The cities of San Francisco, Berkeley, and Los Angeles have local benchmarking and public disclosure programs whose requirements exceed those of the state program. Per the state regulations, a local jurisdiction may request that the Energy Commission provide an exemption from the state reporting requirement for buildings located in the local jurisdiction. Owners of buildings in these jurisdictions may report to the local jurisdiction only, and will not be required to report to the Commission.
