AB 1103 – Energy Benchmarking & Disclosure Services


As of 2015, the California State Legislature repealed Assembly Bill 1103 (AB 1103).

As a result, a new energy disclosure law known as AB 802 was created and is set to go in effect in January 2017. For further information about this new legislation, please visit our AB 802 page.

Please note that for 2016, there will be no energy disclosure law.

Partner Energy is an expert on California’s Assembly Bill (AB) 1103 energy benchmarking and disclosure law and has benchmarked hundreds of buildings through the ENERGY STAR Portfolio Manager®.  We can provide varying levels of assistance to make compliance with AB 1103 as manageable as possible.  The following three services describe different levels of compliance support that are available for commercial building owners: ranging from hands off review assistance to fully guided support throughout the AB 1103 disclosure process.


AB 1103 Reviewed Energy Use Disclosure Report

This report provides the lowest level of assistance and relies on the building owner collecting all property data including physical data, operating characteristics, and utility bills. A client who is already managing their energy usage in the ENERGY STAR Portfolio Manager System can generate an energy efficiency rating for the building through the system and have it professionally reviewed for completeness by Partner Energy staff..

Partner Energy will provide the building owner with an AB 1103 compliance report that includes a signature page (documentation of acknowledgement of receipt by the buyer, lessee or lender, and any other required AB 1103 documentation) and a summary of all building data and supporting documents. For approximately $349, the Reviewed Energy Use Disclosure Report is an extremely cost-effective way to ensure compliance under AB 1103. Technical assistance is provided to clients via email as required.

AB 1103 Audited Energy Use Disclosure Report

Partner Energy offers an Audited Energy Use Disclosure Report option for building owners that want to spend less time collecting and inputting data into the ENERGY STAR Portfolio Manager System. Partner Energy engineers will assist in the data collection process by providing clients with collection forms to record the property’s physical data, operating characteristics and utility bills.  After collection, Partner staff will review the collected data to ensure it is accurate, complete and verifiable, and enter the data into the Energy Star Portfolio Manager. The certified signature page and final report provided by Partner will ensure full compliance, and provide documentation required to apply for the ENERGY STAR label.  For $549, building owners can engage Partner Energy for this report and strike a good balance between minimizing building owner out of pocket costs and saving time that otherwise would have been spent on compliance with the law.

AB 1103 Professionally Prepared Energy Use Disclosure Report

Partner Energy’s most comprehensive product for AB 1103 compliance, the Professionally Prepared Energy Disclosure Report, takes all work out of the client’s hands. During this full-service report, an engineer will conduct a site visit, collecting data about the building’s physical elements, operating characteristics and utility meters.  The data is reviewed to ensure it is complete and verifiable, entered into ENERGY STAR Portfolio Manager, and checked for accuracy again.

The client can receive technical support as required via phone or email. A signature page acknowledging receipt by the buyer, lessee or lender is included in the final report containing all building data and supporting documents required by AB 1103. This comprehensive report ensures full certainty and a convenient way to attain or maintain compliance under the new AB 1103 laws. Please call to obtain pricing for this service.
