Retro Commissioning (RCx) Lite is designed for facilities that may not have the time or financial resources to survey an entire facility. RCx Lite focuses on specific areas of the facility and identifies no- and low-cost energy efficiency improvements that can help reduce usage.

Retro Commissioning (RCx) Lite incentives can defray up to 100% of the survey cost for tune-up projects that have a simple payback period of up to one year. No-cost and low-cost measures that may qualify for RCx Lite incentives include:

• Adjustment of lighting and HVAC operating schedules
• Adjustment of HVAC set points
• Redeployment of inoperable HVAC dampers and controls

A typical facility in Ameren Illinois service territory can expect to achieve an energy savings of up to 30% as a result of the retro commissioning process! Retro Commissioning Surveys will be performed by a pre-approved Retro Commissioning Service Provider (RSP) with proven experience and expertise in large facility systems. Customers may implement their projects using in-house resources, a contractor of their choice, or the RSP. The Retro Commissioning Survey may also identify capital improvement projects (1-10 year payback) that might qualify for additional incentives through Ameren Illinois' Energy Efficiency Program. Projects must be submitted for pre-approval; based on the size and the scope of the survey, we’ll let you know when your project can begin.
