Which process is aimed at ensuring HVAC systems operate according to design specifications and supports energy efficiency and indoor air quality?

• A. A systematic process aimed at ensuring that the HVAC systems within a building are operating according to their design specifications.
• B. Testing, Adjusting, and Balancing (TAB)
• C. Thermal Air Balance
• D. Technical Air Balance

Answer: (B)

Testing, Adjusting, and Balancing is the formal process used to verify that HVAC systems meet their design specifications while promoting energy efficiency and healthy indoor air quality. In practice, technicians measure actual airflow, pressures, and temperatures, compare them to the design values, and then adjust equipment—such as dampers, fan speeds, and valves—to bring the system into balance. This ensures each space receives the intended amount of ventilation and conditioned air, which reduces energy waste from over- or under-delivery and helps maintain proper indoor air quality by delivering the right outdoor air rates and preventing unwanted air mixing. While some descriptions express the goal in general terms, TAB names the specific, standardized procedure used to achieve these outcomes; the other terms aren’t recognized names for this process.
