Large Building Energy Reporting

Large Building Energy Reporting (LBER) Law: 

Massachusetts' Large Building Energy Reporting (LBER) is a state law, from An Act Driving Clean Energy and Offshore Wind (The Acts of 2022 ch.179, § 41), that created M.G.L ch. 25A §20 to require disclosure of Energy Usage data for Buildings greater than or equal to 20,000 square feet (Covered Buildings) starting in 2025.

The law requires electric, gas, and steam utilities to report Energy Usage data on behalf of Covered Buildings. It requires Building Owners or agents of Covered Buildings to report usage of additional energy sources such as oil, propane, wood, and on-site renewable energy generation.

The LBER law provides transparency to building stakeholders like tenants and municipalities about building energy usage. Through tracking building energy consumption, property owners can identify energy-saving opportunities that can reduce costs, emissions, and improve comfort.
