Renew Boston Trust

The City of Boston is leading by example with energy efficiency and resiliency in the City of Boston’s buildings.

"We have a unique opportunity to update our municipal buildings and exterior lighting in a way that preserves Boston’s character and aligns with our broader environmental goals. I am excited to work on ensuring our city is saving energy and the associated costs while bringing us closer to our net zero goals." — Mayor Michelle Wu


Renew Boston Trust (RBT) began in 2017. It is a City program that conducts energy audits and invests in conservation upgrades for municipal buildings. In 2022, Renew Boston Trust extended its scope to include an energy audit of all exterior City-owned lighting. This program is an important tool for the City as it leads by example in reaching carbon neutrality and becoming a Green New Deal city.

Renew Boston Trust was developed in phases. Each phase includes a unique set of municipal buildings. At the end of RBT's Phase 3 and the exterior lighting scope, all City departments that own and operate buildings will have received energy efficiency upgrades.

The initiative is overseen by departments in three of the City’s cabinets:

  1. the Environment Department
  2. the Public Facilities Department, which handles major construction projects for the City, and
  3. the Budget Office, which handles the City’s budget and spending.

Program Updates

JULY 2023

The City will know the energy savings from Phase 1 projects (from July 2022 - June 2023) by October of 2023. In Phase 2, the Renew Boston Trust team is installing equipment at two community centers and a police station. All construction in Phase 2 should be complete by November 2023.

Phase 3 includes several parts. The first part is 70% complete. Renew Boston Trust is replacing over 14,000 lights in City Hall. This project is over 60% complete and ahead of schedule. The second part of Phase 3 started earlier this year. Heating and cooling equipment installations have begun at the Tynan and Murphy schools. Other projects at the Tynan, Murphy, Condon, and Ohrenberger schools will begin later this year.

The exterior lighting audit is complete. The City and the project team are reviewing the results and identifying projects to reduce energy use and emissions.
