Which term describes measuring and adjusting airflow to meet design criteria?

• A. Testing and balancing
• B. Commissioning
• C. IAQP
• D. DCV

Answer: (A)

The term for measuring and adjusting airflow to meet design criteria is Testing and Balancing. In this process, technicians measure actual airflows at supply diffusers, grilles, and returns, compare them to the design values, and adjust dampers, VAV boxes, and other control devices to bring the system into tolerance. This ensures the space receives the intended ventilation rates and air distribution for comfort and energy performance. Commissioning is broader, covering overall verification of system performance and operations, with Testing and Balancing as a key step. IAQP focuses on strategies to achieve IAQ, not the balancing of airflow, and DCV is a control strategy that modulates airflow based on occupancy or sensors rather than the measurement-and-adjustment activity itself.
