The LEAN Multifamily program identifies, scopes, and delivers cost-effective energy efficiency measures for affordable multifamily housing across Massachusetts. These measures include electrification, gas-efficiency, and weatherization. The entire process is managed by the program to ensure high-quality work and energy efficiency equity for disadvantaged communities.

New Ecology acts as an owner’s representative for buildings going through the program, providing the expertise required to manage an energy efficiency design-build project. This ensures that the upgrades will works as intended and deliver the comfort necessary for residents, while maintaining energy efficiency and eliminating the knowledge gap that often exists for affordable housing to access these upgrades.

LEAN is part of Mass Save. The program is jointly administered by the program administrators and the Low-Income Energy Affordability Network (LEAN). To see a full list of Massachusetts Energy Efficiency Program Administrators (PAs) which fund this program, visit leanmultifamily.org.
