IAQ is the subcategory to what division?

Explanation:
Indoor Air Quality (IAQ) deals with how clean and comfortable the air is inside a building, which is directly influenced by how the HVAC system is delivering and balancing air. The Testing, Adjusting, and Balancing (TAB) process is all about measuring airflow, pressures, and air distribution, then making the necessary adjustments so the system meets design requirements and operates as intended. Because IAQ hinges on proper ventilation rates, filtration effectiveness, and controlled air movement, it falls under TAB, rather than the broader HVAC category or other divisions like QA or Safety.
