What role does the Commissioning Provider have during the creation of the Owner ' s...

Under LEED v5 EAp3: Fundamental Commissioning, the Commissioning Provider (CxP) must become involved during predesign or as early as possible and assist in the development of the Owner ' s Project Requirements . The OPR remains fundamentally the owner ' s document because it defines the owner ' s performance goals, functional requirements, and expectations for building systems. The CxP helps clarify these requirements, reviews and updates the OPR through design and construction, and later checks the Basis of Design against the OPR. The CxP does not independently author or publish the document and does not simply supervise the design team while others prepare it. The commissioning process requires active collaboration with the owner to establish a clear benchmark against which design, installation, and system performance can subsequently be verified.
