Role of VAV in Commercial Buildings: How It Works and Why It Matters
The role of VAV in commercial buildings has become central to modern HVAC design, especially where energy efficiency, occupant comfort, and zoning flexibility are critical. Variable Air Volume (VAV) systems are widely used in offices, hospitals, schools, airports, and high-rise buildings because they deliver conditioned air based on actual demand not constant airflow. For HVAC engineers, facility
