Decarbonization Pathways Pilot

The Challenge: Develop Scalable Pathways for Home Decarbonization

Every home is different. Individual homes' clean energy potentials are vastly different, too. Homeowners need customized recommendations for comprehensive energy efficiency and home decarbonization projects. To serve a significant number of homes, program administrators and other practitioners need scalable protocols for assessing homes and developing the decarbonization plans.

About the Decarbonization Pathways Pilot

Through the Decarbonization Pathways Pilot, MassCEC is developing and testing an innovative protocol for comprehensive home decarbonization assessments for single-family and low-rise residential buildings (up to three stories). MassCEC plans to perform the newly developed assessment protocol on a diverse cohort of about 75 homes throughout the Commonwealth whose owners are interested in decarbonizing. In addition to the decarbonization assessment, participants will receive a decarbonization plan, technical assistance, and financial incentives to implement some or all of the recommended decarbonization measures.​

Program Goals

The goals of the Decarbonization Pathways pilot program are to:

  • ​Create and test a model for comprehensive consumer engagement and home decarbonization that could be scaled by Mass Save® or another entity — in service of achieving the state’s decarbonization targets
  • ​Develop consumer-facing resources and showcases to support homeowners and landlords who are ready to take action now and decarbonize their buildings​

The home decarbonization assessment will evaluate several areas — energy efficiency, electrical upgrades, heating and cooling, hot water, cooking & other appliances, and personal transportation — with the goal of eventually eliminating the use of fossil fuels from the home, in addition to promoting efficiency.​

Project Team

Technical Consultant

MassCEC is working with Abode Energy Management to conduct the following tasks:

  • Develop protocols for a decarbonization assessment that build on the framework and successes of the Mass Save® Home Energy Assessment 
  • Create a framework for the recommendations that will come out of the assessment 
  • Produce a structure for customizable individual decarbonization plans based on the assessment's recommendations and the homeowner's goals
  • Provide technical expertise for participants looking to implement decarbonization recommendations

Review Committee

MassCEC has assembled a committee of external experts to review and provide input on the decarbonization assessment protocols, recommendations, and customizable planning tool.

Committee members:

  • Alissa Whiteman, MA Department of Energy Resources
  • Amar Shah, Rocky Mountain Institute
  • Andrew Posner, Capital Good Fund
  • Bob Eckel, Eversource
  • Brendan Delaney, Action Inc.
  • Brian Beote, Action Inc.
  • Briana Kane, Cape Light Compact
  • Frank Nitti, National Grid
  • Greg Phipps, Reading Municipal Light Department
  • John Balfe, Northeast Energy Efficiency Partnership ​
  • Leah Berger, National Grid
  • Nikhil Nadkarni, City of Cambridge

Program Timeline

Who's Eligible to Apply?​

Eligible applicants are residential building owners  of the following building types:

  •    Single-family home
  •    Multi-family building with four (4) or fewer units*
    • Single owner or multiple owners
    • All units in the building must participate

The Pilot is not intended for the following:

  •    Condos
  •    Commercial buildings
  •    New construction or homes built within the last ten (10) years

The home must also meet the following criteria:

  • Must be located in a utility territory that contributes to the Massachusetts Renewable Energy Trust. This includes the Massachusetts service territory of National Grid, Eversource, Until, and municipal light plants that have elected to pay into the Renewable Energy Trust (please see for more information).
  • Must be an occupied residence year-round. For example, summer homes that are unoccupied in the winter are not eligible for the Pilot.

During the Pilot, Applicants should plan to, at a minimum:

  •  Complete all Mass Save® weatherization recommendations.
  •  Install cold-climate heat pumps (Applicants who are replacing their heating or cooling     system and/or plan to install a  whole home heat pump system are preferred).

Can I apply to the pilot if I’ve already installed heat pumps or completed Mass Save® weatherization measures? 

Even if you have already installed heat pumps or completed Mass Save weatherization measures, you are still eligible for the pilot. However, for the first cohort, we are particularly interested in working with participants who are actively going through the process of installing heat pumps. As a result, due to the competitive selection process, there may be a lower chance that you will be selected if you have already installed heat pumps. 

Can I apply to the pilot if I am a condo owner? 

Individual condos units in a larger building or complex are not eligible to participate. At least for the first cohort of the pilot, we want to be able to make comprehensive recommendations for the entire building envelope (i.e., roof/attic, walls/windows/doors, and basement). If all owners of a condoized small multi-family (i.e., four or fewer units) want to jointly apply for the pilot, we would consider that application. 


Can I apply to the pilot if my electricity provider isn’t Eversource or National Grid? 

MassCEC’s Renewable Energy Trust funding comes from electric rate payers, which means that eligibility for this pilot is based on a household's electric utility. Electric customers from National Grid, Eversource, Unitil, Ashburnham Municipal Light Plant, Holden Light Department, Holyoke Gas & Electric Department, Ipswich Electric Department, Russell Light Department, and Templeton Municipal Light Plant pay into MassCEC’s Renewable Energy Trust. Unfortunately, if you are not a customer of one of those utilities you are not eligible to participate in this pilot. For more information, visit this webpage. 

Can I apply to the pilot if I own a triple decker building? 

If you own a triple decker building, please apply instead to the Triple Decker Retrofit Pilot. The affordable housing track is currently accepting applications, with a review deadline of September 2, 2022. The market-rate track will open to applicants later in 2022.
