Building Energy Reporting and Disclosure Ordinance

The ordinance requires Boston’s large- and medium-sized buildings to report their annual energy and water use.

Buildings account for about half of greenhouse gas emissions in Boston. The Building Energy Reporting and Disclosure Ordinance (BERDO) makes building owners, tenants, and other stakeholders more aware of their energy usage and greenhouse gas emissions - and opportunities to reduce both. It also requires the City to make this data public. This helps Bostonians save money and the City achieve its emissions reduction goals, as laid out in its Climate Action Plan.

In 2017, BERDO requires the following portfolios to report their annual energy and water usage for January 1, 2016 - December 31, 2016:

  • Nonresidential buildings that are 35,000 square feet or larger.
  • Residential buildings that are 35,000 square feet or larger, or have 35 or more units.
  • Any parcel with multiple buildings that sum to 100,000 square feet or 100 units.

The Ordinance also requires these buildings to complete an energy assessment or an energy action every five years.

Key dates
  • Reporting deadline for owners: May 15
  • Disclosure deadline for the City of Boston: October 1

Learn about BERDO

BERDO helps property owners understand how their buildings energy performance compares to that of similar buildings nationally, and, after public disclosure, to that of other buildings in Boston.

Owners of multiple buildings can compare energy efficiency across their portfolio, and identify the buildings that are most in need of energy improvements. It also provides tenants with better information on energy efficiency when making decisions about renting or leasing space.

The deadline for reporting is May 15. The City discloses all data to the public on October 1.
