Eligible Upgrades

This list of energy efficiency and renewable energy technologies is a reference tool for the types of projects C-PACE is used to finance. All C-PACE improvements must be permanently affixed to the commercial property and part of a retrofit to existing infrastructure, with the exception of district heating and cooling systems. If an upgrade is not included on this list, Connecticut Green Bank will review proposed additions on a case-by-case basis.

Non-energy-saving measures directly related to installation of an energy conservation measure may be determined as eligible and included in the financing as long as the project’s SIR remains greater than 1 and if the measure will benefit the qualifying commercial real property (e.g. a roof to support solar panels or the pipeline infrastructure as necessary to enable a natural gas conversion).
