Program Summary
The Columbia Water & Light (CWL) Home Performance with ENERGY STAR program allows Columbia residents to finance energy efficiency improvements to homes with affordable, low-interest loans with terms up to 10 years. If a CWL customer has a good credit history and owns an eligible home, loans can be used to install insulation, heating and cooling systems, solar water heating and solar space heating systems, and other eligible efficiency technologies.
The program involves several steps. First, a CLW certified contractor conducts a Home Performance with ENERGY STAR assessment, which provides information to the homeowner on cost-effective ways to improve the home's energy efficiency. The homeowner then completes and submits a loan application. Improvements may be started once the loan is approved. Once projects are completed, CWL staff will conduct a post-inspection.
