"Commissioning is a systematic and documented process of ensuring that specific building systems perform interactively according to the design intent and the owner's operational needs."
Ideally, the commissioning process will begin in the design phase, with a review of the design intent and constructability/maintainability issues. The process then continues through the construction and acceptance phases, with submittal review and documented verification of proper systems installation and functional performance. Typically, commissioning then concludes with O&M manual review and verification of operator training, and may include additional support through the warranty period.
