Commissioning (Cx) is a systematic process for ensuring building systems (mechanical, electrical, plumbing, envelope, etc.) function and perform as intended. It includes verification of equipment installation and observation of modes of operation. This process can be applied to new buildings and major renovations (Cx) or existing buildings (Retro-Cx). Software data analytics can also be set up to continuously monitor operations and flag potential issues (Monitor Based or Ongoing Cx).
