What does commissioning mean?

Commissioning (Cx) is, in general, a quality assurance process for buildings. It involves achieving, verifying, and documenting the performance of each system to meet the building's operational needs according to the owner's functional criteria.

In the practice, one can differentiate 4 types of commissioning:

  • Initial Commissioning (I-Cx) is applied to new buildings
  • Retro-Commissioning (Retro-Cx) is first-time commissioning for an existing building
  • Re-Commissioning (Re-Cx) is a commissioning process implemented after I-Cx or Retro-Cx
  • On-Going Commissioning (On-Going Cx) is a commissioning process conducted continually for the purposes of maintaining, improving and optimizing the performance of building systems after I-Cx or Retro-Cx.
