Optimize Energy Performance

Receive a fully-funded study performed by a ComEd-approved Service Provider. Services valued at up to $100,000 are provided to identify no- and low-cost operational improvements to your energy-using systems. You may also qualify for an incentive based on the energy savings achieved at your facility.

An RCx project may help facility owners, managers and operators:

  • Improve and maintain occupant comfort and productivity.
  • Increase property value.
  • Reduce maintenance needs and extend equipment life.
  • Gain deeper understanding of building systems and controls.
  • Improve energy performance and energy benchmarking scores.

To receive the study, participants must commit to spending $5,000 to $25,000 on no- and low-cost energy-saving improvements. The commitment level depends on your project size.
