What is occupant comfort verification, and how is it conducted?

• A. A survey of occupant satisfaction only, without measurements.
• B. Assessment of thermal comfort and IAQ; uses sensors and occupant feedback; results guide adjustments.
• C. Review of system manufacturer warranties.
• D. Verification of equipment installation dates.

Answer: (B)

Occupant comfort verification means confirming that the building actually delivers the intended comfort and air quality by combining objective measurements with the occupants’ feedback. In practice, this involves monitoring thermal conditions and indoor air quality with sensors (temperature, humidity, air velocity, CO2, VOCs, particulates, etc.) in representative zones and gathering occupant input through surveys or interviews. The collected data and feedback are then used to fine-tune controls, adjust setpoints and ventilation rates, or modify schedules and system operation so comfort goals are met. Options that rely only on surveys without measurements or that focus on warranties or installation dates don’t assess actual comfort performance.
