Large Building Energy Reporting

The Commonwealth's policy requiring disclosure of energy information for large buildings

An Act Driving Clean Energy and Offshore Wind (The Acts of 2022 ch.179, § 41) created M.G.L ch. 25A §20 to require disclosure of energy use data for buildings over 20,000 square feet starting in 2025.

The law requires electric, gas, and steam utilities to report usage data on behalf of covered buildings. It requires owners or agents of covered buildings to report usage of additional energy sources such as oil, propane, wood, and on-site renewable energy generation. 

NEW! Large Building Energy Reporting (LBER) Regulation

On December 23, 2024, the Joint Committee on Telecommunications, Utilities and Energy (TUE) issued its report on the regulations and took no formal position on the substance of the regulations. On December 30, 2024, DOER filed its final regulations with TUE, which are identical to those filed with the Committee in November. The Department will file the final regulations with the Secretary of State not earlier than 30 days after December 30, 2024.

In addition, DOER provides the following resources for stakeholders:

• TUE Committee filing cover letter

• Final regulations

• A redlined version of the draft regulation showing what changes DOER made based on public comments

• All written public comments received 

• A summary of the comments and DOER’s responses

Additional LBER Policy Development

In the final regulation draft, DOER commits to continuing the public conversation about LBER implementation through public comment periods on the following Guidelines:

• Distribution Company, Steam Distribution Company, and Municipal Utility Reporting 
• Building Owner Reporting 
• Additional Owner Disclosure 
• Exempt Building Uses 
• Methodology for Calculating Greenhouse Gas Emissions

Details about the opportunity to weigh in on these topics will be posted on this page in the coming months. 

LBER Implementation

DOER will post the final covered buildings list notifying parties of which buildings’ energy must be reported by March 30, 2025. The first reports of energy usage will be due on June 30, 2025, and DOER will publish the first disclosure reports on October 31, 2025.

To ensure the covered buildings list is accurate, DOER will publish a draft list in January 2025, notify owners of record that they are included on the list, and give building owners and agents time to refine the list and update their contact information. 

To be notified of LBER policy developments, please sign up for DOER’s BER mailing list. If you have questions in the meantime, please email [e-mail].
