During commissioning, which documentation should be created to verify system performance?

• A. Only a basic checklist.
• B. Documented results of airflow, fan operation, damper function, interlocks, and overall performance.
• C. A verbal report.
• D. No documentation is required.

Answer: (B)

When commissioning, you need a verifiable record showing the system actually meets its design and safety requirements. The strongest documentation collects quantified results for all critical functions: measured airflow at representative locations, proper fan operation (speed, power, vibration), damper function (correct opening/closing, response time, fail-safe status), interlocks (proper sequencing and safety checks), and overall performance compared to the design criteria. This creates a traceable, objective record that can be used for future maintenance, code compliance, and performance verification. A basic checklist without measured values doesn’t prove the system is performing as intended. A verbal report lacks objective data, and no documentation provides no lasting record of how the system performed during commissioning.
