What activity best supports occupant comfort during Cx?

• A. Turn off HVAC to avoid complaints
• B. Collect occupant feedback and adjust controls accordingly.
• C. Assume occupants are always silent
• D. Replace all HVAC equipment before feedback

Answer: (B)

Gathering occupant feedback and using it to tune the controls is essential for ensuring comfort during the commissioning process. Comfort is subjective and varies from person to person, so directly asking occupants about their experience with temperature, draft, and overall environment provides real insight that sensors and calculations alone can’t capture. When feedback is collected, the team can adjust thermostat setpoints, vibration and fan speeds, zoning, schedules, and control strategies to better match the intended comfort criteria. This creates a practical, iterative loop where design expectations are validated against actual occupant experience, and issues like uneven temperature distribution or overactive equipment can be identified and corrected before turnover.

Turning off HVAC to avoid complaints defeats the purpose of Cx and removes the opportunity to verify whether the system can meet comfort goals. Assuming occupants are always silent ignores real conditions and leaves problems unaddressed. Replacing all HVAC equipment before gathering feedback is wasteful and may not address the actual comfort issues if the controls and balancing are misaligned.
