Commercial property assessed clean energy (CPACE) financing is an innovative tool that provides low-cost, long-term financing for energy efficiency, renewable energy, water conservation, and resiliency projects in commercial buildings. Cook County commercial property owners can obtain up to 100% upfront financing from private capital providers for qualified upgrades such as HVAC, lighting and solar photovoltaic systems, and many more, in both existing buildings and new construction projects. By doing these efficiency improvement, annual utility savings are generally greater than the annual C-PACE financing payments, generating positive cash flow from day one.
