Which items are typical acceptance criteria for HVAC performance verification?

• A. Design setpoints, allowable temperature/humidity ranges, air changes per hour, CO2 levels, and energy usage thresholds.
• B. Contractor vacation schedule, parking allocation, and lunch breaks.
• C. Weather data for past year.
• D. Roof material specifications.

Answer: (A)

Acceptance criteria for HVAC performance verification are the measurable operating parameters used to confirm the system performs as it was designed. The best choice reflects the key items that link system operation to design intent: design setpoints specify the target conditions the system should achieve; allowable temperature and humidity ranges outline the tolerance within which comfort and IAQ must be maintained; air changes per hour establish the minimum ventilation and mixing to dilute contaminants; CO2 levels serve as a practical indicator of whether ventilation is sufficient; and energy usage thresholds ensure the system meets efficiency expectations while delivering required cooling or heating. Together, these criteria provide objective checks during verification to show the system can operate under real conditions as intended. The other options include elements that are not related to HVAC performance verification, such as administrative schedules, irrelevant weather data, or roof material specs.
