Building Energy Benchmarking: Are We There Yet?

LAOfficeBuildingIn a classic case of “the devil’s in the details,” Assembly Bill 1103 (“AB 1103”), which mandated the disclosure of energy-usage data of commercial buildings in certain transactions, has yet to be implemented nearly four years after it was first enacted. The legislation set a deadline of January 1, 2010 for building owners selling, leasing or financing an entire non-residential building to deliver energy consumption information utilizing the U.S. Environmental Protection Agency’s Energy Star Portfolio Manager program (EPA Portfolio Manager). (A more comprehensive description of AB 1103 is provided here.) The 2010 deadline was extended indefinitely in 2009 by Assembly Bill 531 to allow the California Energy Commission (CEC) to complete the rule-making process for the adoption of implementing regulations.

So the unanswered question is: When will AB 1103 finally take effect? The answer, for the moment, is that implementation is at least nearly a year away. The earliest possible kick-off date is July 1st of next year. In order to make this schedule, the revised draft regulations issued for public comment in August (Revised Draft Regulations) would need to complete the public comment process followed by adoption of the final regulations by the CEC by late spring 2012.


A CEC staff workshop to solicit comments on the Revised Draft Regulations has been set for September 12, 2011 in Sacramento. If adopted as proposed, implementation would roll out in stages beginning on July 1, 2012. At that time, the AB 1103 disclosure requirements would take effect for non-residential buildings of 50,000 square feet or more or those solely occupied by the owner. The second phase would cover buildings of 10,000 to 50,000 square feet as of January 1, 2013, while remaining buildings would be required to comply as of July 1, 2013. Buildings under 5,000 square feet not solely owner-occupied would be exempt.

The Revised Draft Regulations released in August incorporate changes to the May 2010 version to reflect the first round of public input and the recommendations of a working group formed in 2009 to provide advice to CEC staff. The provisions call for building owners to disclose information in the form of a Disclosure Summary Sheet, Statement of Energy Performance, Data Checklist and a Facility Summary to prospective buyers, lessees or lenders of an entire building. The information is to be provided as soon as practicable before execution of a sales contract, a lease or a loan application. At least thirty days before a required disclosure, the building owner must open an account at the EPA Portfolio Manager website and request that all utility companies serving the building release energy-use data for the most recent twelve months to the owner’s EPA Portfolio Manager account.

After all utility companies have uploaded the building’s energy use data, the CEC’s AB 1103 compliance website will generate the Disclosure Summary Sheet, allowing the building owner to complete the Compliance Verification Report and to download the building’s Statement of Energy Performance, Data Checklist and Facility Summary from the EPA Portfolio Manager data. To address those cases where information is not timely available through this process through no fault of the owner, an approximation based on the best information available to the owner may be used, provided that the approximation is clearly identified in the disclosure materials.

The public comment period on the Revised Draft Regulations is scheduled to close on September 16, 2011. Thereafter, the CEC will begin formal rule-making proceedings. Should you wish to provide comments, the public notice of the staff workshop on the CEC’s website is available here.
