Renew Boston Trust Phase III

Phase 3 is the most ambitious phase of Renew Boston Trust yet. Schools will receive a majority of the current Phase 3 budget of $112.5 million. City Hall will receive a comprehensive lighting upgrade that will save over one million kilowatt-hours (kWh) per year.

This phase is broken up into four parts given the size and complexity of the scope of work. As of December 2022, the City has contracted for the full scope of work in the first two parts. The scope for the first part includes lighting, water conservation, building envelope, and pipe insulation upgrades in the following buildings:

  • nine schools
  • one police station, and
  • one property management facility (City Hall).

The scope for the second part is focused on four schools and will include substantial mechanical equipment replacements, building management system upgrades, and some additional lighting work.

This first part of Phase 3 will cost $19.8 million. It will deliver $720,177 in energy and water savings per year. The second part of Phase 3 will cost $32.7 million and will deliver $218,641 in energy and water savings per year. Future parts of Phase 3 — to be decided by late-2023 — will include:

  • the installation of additional building controls
  • new heating and cooling equipment for five other schools in Phase 3, and
  • a selection of new rooftop solar arrays.
