Loans Improving Multifamily Efficiency (LIME)


LIME financing can help your multifamily property make energy improvements (including going solar) a reality. Connecticut Green Bank has partnered with Capital For Change (C4C) to provide multifamily energy financing for owners seeking to improve the energy performance, economics, and health and safety of their properties. Loans are generally able to be repaid based on new cash flow created from the estimated energy, operations, and maintenance cost savings for the project.

Program benefits

  • Save money on energy and operating costs
  • Increase the value of your property by upgrading to efficient, high-performance equipment
  • Improve occupancy rates by reducing tenant utility costs
  • Improve tenant comfort and safety

Any market-rate or affordable multifamily property with 5 or more units is eligible for this financing. This includes partnerships, trusts, LLCs, sole proprietors, public housing authorities, non-profits, and condo/co-op associations, as as well as project sponsors who would, in turn, make a loan to an LLC or Partnership.

  • Energy efficiency and renewable energy improvements. 
  • Up to 25% of loan proceeds may be used for non-energy efficiency improvements (structural, health/safety, etc.), provided there are sufficient savings.
  • All fees and soft costs may be rolled into the loan. This includes items such as verification of proper installation, legal fees, and life of loan performance monitoring for each unit.
