The Commissioning Process (Cx) is a quality-focused process for enhancing project delivery. Cx begins at project inception and continues for the life of the facility.
ASHRAE Standard 202 describes the overall minimum Cx necessary to provide a uniform, integrated, and consistent approach for delivering projects and to provide information for operating facilities that meet the Owner’s Project Requirements. This standard also describes the general requirements for a training program for continued successful system and assembly performance.

The revised 2024 edition includes:
Revised Title, Purpose, and Scope to clarify the standard applies to new buildings and new systems within existing buildings
Requirements for what the Cx Provider must provide for Owner review and acceptance when initiating Cx
Clarity to Construction Phase activity requirements
Ongoing Cx requirements related to new construction
Clarification of Preliminary Cx Report vs. Final Cx Report
