Boston’s First Networked Geothermal System: A Revolutionary Project at Franklin Field Apartments

Boston is on the brink of a major change in how it deals with renewable energy and living spaces. Dorchester’s Franklin Field Apartments are going to get the city’s first connected geothermal system for heating and cooling, showing a serious move to an eco-friendly tomorrow. Mayor Michelle Wu made this announcement about the project, which is a joint effort by the Boston Housing Authority (BHA) and National Grid.

Overview of the Geothermal System

We’re upgrading from an old gas boiler to cutting-edge geothermal tech. This fancy setup taps into the stable temps of the Earth’s ground through a network of pipes underground. It’ll regulate the temperature inside buildings better, keeping them warm or cool as needed. Plus, geothermal heat pumps are way more effective – they beat out traditional electric heaters by a factor of four. The whole shebang will have special holes drilled for the system, a building to house the pumps, and some pipes running sideways to spread the heat or cool around.

  • Efficiency: Switching to geothermal heat pumps could mean big savings on electricity bills – we’re talking possibly 12% off the going rate.
  • Environmentally Friendly: With this project, we’re on our way to making our buildings and power grid cleaner and greener.
  • Economic Impact: By diving into this venture, we expect to dish out well-paid eco-friendly jobs. It’s also gonna spruce up living spaces for folks in the area.

Impact on Residents and Community

The upgrades will provide 129 apartments in seven buildings with efficient in-unit cooling for the first time. This move eliminates the need for inefficient window air conditioners, previously bought by tenants. Moreover, the BHA will invest in the electrification of heating and domestic hot water equipment within the buildings, encompassing retrofits, electrical upgrades, and replacement of appliances and heating equipment.

  • Improved Quality of Life: The project promises a healthier living environment and addresses issues like drafty windows and poor ventilation.
  • Education and Training: Residents will be trained on using new induction stoves, and the project’s impact on indoor air quality will be studied.
  • Federal Support: The city has received $1 million in federal funding to replace 80 gas stoves with electric ones, enhancing the project’s scope.

Project Timeline and Execution

The design phase is set to begin in early 2024, with construction activity scheduled for 2025. Minimal disruption is expected for residents, with temporary relocation required only for a few days. The BHA will lead resident engagement throughout the year.

  • Collaborative Effort: The project involves a partnership with National Grid, utilizing federal Capital Fund Program resources and state energy efficiency programs.
  • Responsible Execution: The BHA will handle the work within the buildings, including all necessary retrofits and upgrades.

Broader Implications and Future Plans

This project is not just a local initiative but a model for sustainable living that could be replicated across the country. It represents a paradigm shift in how cities can collaborate with utility companies to create green infrastructure.

  • Innovative Approach: The project is one of the first in the country to embrace new clean energy technology in public housing.
  • City’s Green Goals: This initiative is a crucial step towards meeting Boston’s goal for the BHA to be fossil fuel-free by 2030.

Future Outlook for Geothermal Energy in Urban Settings

Turning the Franklin Field Apartments project into a success could show other cities how to do it right. With climate change becoming a big problem, and the need for energy that doesn’t hurt the planet, what Boston is doing shines like a light showing the way forward.

Replication Potential: The way this project works can be used as a model, maybe in different housing projects and city areas too. It could help spread the use of earth energy technology.

Job Creation: And it’s not just about helping the earth. Starting projects like these could also create new jobs in the eco-friendly energy business. People could find work building or taking care of these earth energy setups.

Community Engagement: Another big thing with this project is that it gets people living in the area involved. It makes sure that everyone isn’t just getting something out of it, but also playing a part in making the switch to cleaner ways of getting energy.


Franklin Field Apartments’ new geothermal system is an exciting step forward in making city life greener. It shows the city cares about fresh ideas, taking care of the environment, and making sure people are living well. Mayor Wu pointed out that this isn’t only about better homes – it’s also about building a better future for everyone who comes next.
