Which of the following is a commissioning requirement to fulfill LEED EA Prereq 1?

• A. Must review the OPR and DID
• B. Must create and execute the Cx Plan
• C. Must complete and submit a Cx final report
• D. Must verify installation and performance of systems to be commissioned

Answer: (B)

Fundamental commissioning hinges on having a formal, written plan that defines how the energy systems will be commissioned and how their performance will be verified. The essential step is to create and execute the Cx Plan, because this plan lays out the scope, owner project requirements, basis of design, sequences of operation, required tests, acceptance criteria, responsibilities, and the schedule for verification. It provides the structured approach that ensures the commissioning process is actually carried out and traceable from design through construction and into occupancy.

While other elements like reviewing owner requirements, documenting final reports, or performing installation verifications are important parts of the overall process, they are activities carried out within the framework of the Cx Plan. Without drafting and following this plan, there’s no formal mechanism to verify that systems meet the intended performance and energy targets, which is what LEED EA Prerequisite 1 requires.
