Retro Commissioning (RCx Lite) is designed for facilities that have 20,000 to 100,000 sq ft of air-conditioned space and 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.

Incentives through this option can cover up to 100 percent of the survey cost for tune-up projects that have a simple payback period of up to one year. 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 percent as a result of RCx Lite. Retro-commissioning survey work must be performed by an Ameren Illinois Energy Efficiency Program Retro-Commissioning Service Provider (RSP). System adjustments may be performed by an RSP, an in-house resource or a contractor of your choice.
