C-PACE Financing
Flexible, sustainable, cost-effective capital

About C-PACE
Commercial Property Assessed Clean Energy is an innovative financing mechanism designed to fund energy efficiency, renewable energy, and resilience projects for commercial properties. C-PACE provides building owners with the capital necessary to fund energy-related deferred maintenance upgrades, support new construction costs, make properties more resilient, and provide access to renewable energy.
With its long repayment terms and property tax-based model, C-PACE minimizes upfront costs while maximizing environmental and financial returns.

- Access to affordable, long-term financing.

Benefits:
- Boosts property value.
- Reduces operating costs.
- Transferable to new owners upon property sale.

- Typically off-balance sheet.
- No impact on owner’s debt capacity.
Where C-PACE Works
Programs are available in many states across the U.S., tailored to local regulations.
