Program Application GoalEfficiency Maine is pleased to offer the Multifamily Efficiency Program, an initiative targeting comprehensive energy efficiency in Maine’s small to medium multifamily buildings.

Fast Facts about the Multifamily Efficiency Program

  • All multifamily buildings with between 5 and 20 apartment units per building are eligible to participate
  • The Program is available to all income levels including affordable housing units and market rate units.
  • The Program is not restricted by fuel type. Buildings that use various fuel types – including but not limited to: electricity, natural gas, oil and propane — may participate.
  • Some examples of common improvement measures include:
    • Insulation and air sealing
    • High efficiency boilers and furnaces
    • Boiler controls
    • High efficiency water heaters, lighting and air conditioners
    • ENERGY STAR Appliances (refrigerators, washers, etc.)
    • Low-flow shower heads
    • Programmable thermostats
    • Pipe insulation

How Building Owners Could Benefit — A Sample Project

A 12-unit building is projected to reduce energy use by 20%
through the implementation of the following measures:
  ✔   Attic insulation and air sealing
  ✔   High-efficiency boiler replacement with indirect hot water heaters
  ✔   In-unit and common area lighting replacement
  ✔   Installation of low-flow fixtures in bathrooms and kitchens
  ✔   Installation of programmable thermostats
The benefits of these measures include potential incentives of up to $19,200 for the building owner, plus long-term energy savings and reductions in energy bills for years to come!

Multifamily Efficiency Program Case Studies
Windham: 20-unit housing complex gains energy savings.
Bangor: Seven-unit apartment building is more energy efficient and more comfortable.


Background: In response to a US Department of Energy, State Energy Program Special Project competitive solicitation, and in conjunction with the Governor’s Office of Energy Independence and Security, Efficiency Maine Trust (Efficiency Maine) submitted a proposal titled “Strengthening Retrofit Markets for Comprehensive Savings in Multifamily Buildings”. Subsequently, Efficiency Maine Trust was awarded funding under DOE’s SEP Special Project funds.
