The Low-Income Multifamily Energy (LIME) Loan supports energy improvement projects for low- and moderate-income properties. Connecticut Green Bank has partnered with Capital for Change (C4C) to provide unsecured multifamily energy financing for owners seeking to improve the energy performance, economics, and health and safety of their properties. Loans are repaid from energy cost savings for terms up to 20 years.


The program is open to multifamily properties that are partnerships, trusts, LLCs, sole proprietors, public housing authorities, non-profits, condo/co-op associations, etc. Must be 5 units or more, and at least 60% of units must be designated affordable to households at no greater than 80% of Area Median Income (AMI)

Preferred consideration is given to “high impact” properties such as:

  • HUD-financed properties, including housing authorities
  • CHFA-financed and FHA-insured developments
  • Properties in low- or moderate-income geographies
  • Transit-oriented development complexes

Program Description

The LIME loan can be used for:

  • Energy efficiency and renewable energy improvements as provided in a lender-approved scope of work
  • Up to 25% of loan proceeds may be used for non-energy efficiency improvements (structural, health/safety, etc.), provided there are sufficient savings to carry the costs
