Large Building Energy Reporting Results

Explore annual energy use and emissions data for large buildings in Massachusetts.

Massachusetts requires utilities and building owners to report annual energy use for buildings that are 20,000 square feet or larger.  The Large Building Energy Reporting (LBER) program makes this data available to the public.  The reports and interactive map below show reported energy use and estimated greenhouse gas emissions.

LBER Results Map and Database

The map below shows reported energy use and estimated greenhouse gas emissions for large buildings in Massachusetts.  To find reporting results for certain buildings, take the following steps:

1. Select the reporting year you want to view. 
2. Search for a building address or UBID or browse buildings by city 
3. Use the filters to explore the results. 

Changing the reporting year will reset the filters.

A Note About 2025 BERDO Data

Boston’s BERDO Review Board extended the 2026 reporting deadline for buildings covered by its Building Emissions Reduction and Disclosure Ordinance (BERDO) from May 15 to August 15.  DOER has not yet received all 2025 energy use data for these buildings.  As a result, some BERDO buildings have missing or incomplete data on the map.  DOER will update the results as more data becomes available.
