Initiative for Electrification in New Affordable Multifamily Housing

The Initiative for Electrification in New Affordable Multifamily Housing is funded through the Inflation Reduction Act (IRA) and offers rebates for qualifying efficient HVAC heat pump systems in new construction of multifamily buildings that will serve low-income households. This initiative is being launched under a Funding Opportunity Notice (FON or “opportunity”) administered by Efficiency Maine’s Commercial and Industrial Prescriptive Initiatives (CIPI). Interested participants can find more information about this program and instructions on how to apply in the FON document posted below under Program Documents.

Eligible Participants:

Owners of multifamily buildings that are planned to be built within which at least 50% of the dwelling units will be reserved for low-income households, designated as:

  • Public Housing (housing owned and operated by Public Housing Authorities),
  • Privately owned multifamily buildings receiving project-based assistance (Section 8, Section 202, Section 811),
  • Privately-owned multifamily buildings that house residents receiving tenant-based assistance, OR
  • Section 42 Low Income Housing Tax Credit (LIHTC)

Eligible Buildings:

  • Single multifamily buildings with 18 or more dwelling units
  • Campuses of multifamily buildings with 18 or more total dwelling units, where each individual building has at least six (6) dwelling units

Eligible Equipment:

  • Mini-split heat pumps
  • Variable refrigerant flow (VRF) systems
  • Heat pump rooftop units (RTUs)
  • Single package heat pumps (with through-the-wall outdoor air ducting)

    Steps to Participate in the Initiative

    1. Review the Funding Opportunity Notice. 
    2. Submit Application A: Intent to Enroll via the form below. (This includes basic contact/building info and anticipated equipment types.) 
    3. Develop a project scope and select a qualifying installer. Then the participant (or their installer) submits Application B: Project Design and Installation to Efficiency Maine. (This application includes specific information on HVAC system design, equipment, and configuration, along with other required eligibility documentation.) 
    4. Efficiency Maine reviews Application B and, if compliant, issues an Incentive Agreement (i.e., contract). Participant signs the Incentive Agreement to secure a rebate reservation.
    5. After project is installed and commissioned, participant (or their installer) submits all required post-completion documentation to Efficiency Maine. 
    6. Efficiency Maine reviews all post-completion documentation and performs an on-site inspection. 
    7. Efficiency Maine issues project rebate.
