Retrocommissioning (RCx)

Retrocommissioning (RCx) is one of many programs driving the University of Illinois’ success in energy conservation. RCx optimizes a building’s heating, ventilation, and cooling systems and controls to maximize energy savings while maintaining occupant comfort. 

Since August of 2007, RCx teams have updated and upgraded systems in 80+ campus buildings, reducing energy consumption by an average of 27% and avoiding $84M in utility costs for over 10 million gross square feet of facilities. RCx will continue to pay dividends in energy savings and efficiency gains as deferred maintenance is taking a toll on campus buildings, wasting energy and consuming financial resources.
