Table of Contents Hide Table of contents× Show More Table of contents You skipped the table of contents section. DOER’s Affordable Housing Decarbonization Grant Program was created in 2023. The large-scale grant program funds deep energy retrofits and decarbonization projects in the affordable housing sector that benefit low- and moderate-income residents.

The objectives of the program are to improve public health, preserve housing affordability for residents, provide local workforce opportunities, and accelerate Massachusetts’ clean energy transition. The decarbonization of Massachusetts’ existing buildings is a critical component of the Commonwealth’s strategy to achieve net-zero emissions by 2050.

Projects will improve energy efficiency, install solar panels, make improvements like roof repairs and electrical updates, and electrify buildings through ground and air source heat pumps and other electrical appliances for low- or moderate-income housing. Applicants seeking more than $1 million must commit to providing opportunities for the local workforce.

The program will provide significant investments in the building sector, and leverage programs like Mass Save® to help affordable housing developments lower emissions and energy use. Health benefits for residents of retrofitted buildings will include indoor air quality improvements and local air pollution reduction.

Program benefits include higher performing buildings that offer residents better indoor air quality and comfort, lower ongoing energy costs for residents and affordable housing providers, the opportunity for affordable housing providers to upgrade their housing stock, and healthier air in the communities were housing is located. ## First and Second Grant Rounds The first round of grants under this program was announced in November 2023.

The grants will be used to fund deep energy retrofits and energy efficiency upgrades, building system electrification, and onsite renewable energy generation in ten affordable housing developments in communities across Massachusetts. The second round of grants was announced in July 2024.

The grants will help affordable housing properties in five communities lower energy demand and decarbonize through deep energy retrofits, energy efficiency upgrades and building electrification. Projects awarded funding in the first two rounds follow. Project descriptions can be found in the announcements.
