The Commissioning (Cx) Plan is a foundational document that outlines the scope and activities of the commissioning process. At a minimum, the plan should include an overview of the Cx program, which details the objectives and goals, the roles and responsibilities of the project team members involved in the commissioning process, and the sequence and timing of process activities. This ensures that all stakeholders understand the commissioning process and are aligned with its implementation.

The requirements for the contents of a Commissioning Plan are detailed in the Energy and Atmosphere Credit for Existing Building Commissioning under the LEED for Building Operations and Maintenance (O+M) reference guide. It is also highlighted in the LEED AP O+M training materials that a comprehensive Cx Plan is integral to documenting the systematic process of ensuring building systems perform interactively and efficiently.
