While commissioning is particularly effective in new construction, it can also be very valuable in taking a thorough second look at existing facilities. Retro-commissioning is a process similar to the commissioning of a new facility. The purpose of retro-commissioning is to identify improvements in existing facilities to optimize systems performance and return critical systems back to reliable operation.

Retro-commissioning symptoms:
  • High maintenance costs
  • Failure of backup or redundant power systems
  • Failure of backup or redundant HVAC systems
  • Unreliable Building Management System (BMS) controls
  • BMS overrides are necessary to make systems function
  • False Alarms (BMS or Fire Protection)
  • Poor indoor air quality
  • Poor occupant comfort
  • Reduced work productivity
