What are the six main items regarding retrocommissioning during the planning phase?

Explanation:
In this planning phase the focus is on establishing who leads the RCx effort, what will be included, and how the work will be approached. The process starts with the owner selecting the CxA, so there is a clear point of responsibility and authority to drive the activities. Next comes developing the Cx scope, which defines exactly which systems, spaces, and performance goals will be addressed and sets boundaries for the retrofit and verification work. Then the CxA reviews existing documentation to understand the original design intent, equipment lists, control schemes, and any past commissioning or operation notes. After that, on-site surveys of the existing conditions are conducted to capture what is actually installed and how it’s functioning, including any discrepancies between drawings and reality. With a solid grasp of both documentation and field conditions, the CxA reviews the system operations and control sequences to confirm how the building should operate, identify misalignments, and determine what needs verification or adjustment. Finally, all of this is synthesized into preparing the Cx plan, which formalizes the approach, scope, schedule, roles, deliverables, and acceptance criteria for the retrocommissioning effort.
