The ordinance requires Boston’s large- and medium-sized buildings to report their annual energy and water use to the City. This year’s deadline is Monday, May 15th.


Buildings account for over 70% of greenhouse gas emissions in Boston. The Building Energy Reporting and Disclosure Ordinance (BERDO) is one of the many tools at the City’s disposable to effect change in this critically important sector for the environment and climate.

BERDO requires all residential and commercial buildings 35,000 gross square feet, or 35 residential units, and larger to report their energy and water data to the City. The City then makes this data available to the public through the Analyze Boston open data web portal and our interactive BERDO map. BERDO further requires that all buildings covered by it complete either an energy audit or improve their energy performance by 15% within 5 years.

By complying with BERDO, building owners, tenants, and other stakeholders become more aware of their energy usage and greenhouse gas emissions, as well as opportunities to reduce both. By making this information public these stakeholders are also able to compare the building’s energy performance to its peers, improving market transparency. Because you can’t improve what you do not measure, BERDO gives the City and utilities vastly superior data in designing programs to reduce emissions and help building owners.

In all, BERDO helps Bostonians save money and the City achieve its emissions reduction goals, as laid out in the Climate Action Plan.

The reporting deadline is quickly approaching. Building owners, managers, and occupants of buildings 35,000 gross square feet, or 35 residential units, and larger have until May 15th to enter their data into the ENERGY STAR Portfolio Manager platform and submit it to the City on time.
