During HVAC functional performance testing, what is the responsibility of the CxA?

• A. Directing, witnessing, and documenting the tests
• B. Performing the tests personally
• C. Authorizing vendor invoices
• D. Setting the project budget

Answer: (A)

Directing, witnessing, and documenting the tests during HVAC functional performance testing is the CxA’s responsibility. The CxA leads the testing activities, ensures test procedures follow the commissioning plan and project requirements, and coordinates with contractors and engineers. By witnessing, the CxA provides independent verification that tests are performed correctly and that the results reflect the system’s design intent and the specified performance criteria. By documenting, the CxA captures test data, observations, deviations, and corrective actions, creating a traceable record for the commissioning report and future operations. This oversight helps confirm the systems meet the owner’s requirements before handover and occupancy. This role is not to perform tests personally, nor to approve vendor invoices or set the project budget.
