What is Retrocommissioning?

Retrocommissioning (RCx) is a systematic process for investigating an existing building’s operations to identify operational improvements, achieve energy savings, and improve occupant comfort. The process focuses on the operation of mechanical equipment, lighting, and related controls and is intended to optimize how equipment operates as an integrated system. RCx projects can produce savings of 5-20% of total building energy costs, with a simple payback from energy savings alone averaging less than 2 years.

Common issues found and addressed through RCx include:
  • Simultaneous heating and cooling
  • Lighting and HVAC running when not required
  • Controls needing to be retuned
  • Critical control sensors out of calibration
  • Automated lighting controls not operating as expected

RCx benefits you by:
  • Identifying and fixing O&M problems
  • Reducing energy and maintenance costs
  • Increasing net operating income
  • Training operating staff to increase skill levels
  • Improving building documentation
