Retro-Commissioning (RCx) Study

For Iowa customers only

A Retro-Commissioning (RCx) Study identifies ways to optimize your facility’s direct digital controls (DDC) or process controls. Most solutions will be no- to low-cost operational and maintenance adjustments that may result in significant energy and cost savings.

Consider a Retro-Commissioning (RCx) Study if your building meets the following requirements:

  • Minimum of 20,000 square feet
  • DDC system or process controls that are two to 10 years old and do not need any capital repairs
  • No major system renovation plans for the area under consideration
The study provides:
  • Information on reprogramming the building’s DDC or process controls
  • A design and control sequence with detailed instructions for reprogramming the controls
  • Real-time verification to assure all controls are working properly
  • Building management training to maximize the new system parameters
  • Twelve-month comparison of pre- and post-RCx Study energy- and cost-savings
Alliant Energy will reimburse 50% of the RCx Study cost upon completion of the study. Alliant Energy will reimburse the remaining 50% of the study cost after the RCx Study recommendations with a payback of two years or less have been completed and verified.

How do I qualify?

A RCx Study must be conducted in a building that Alliant Energy supplies the primary heating or cooling energy.
