VAV - Variable Air Volume
Energy-Efficient Air Distribution
System Overview
Variable Air Volume (VAV) systems vary the volume of conditioned air supplied to different zones based on demand, rather than varying the temperature. This results in significant energy savings compared to constant volume systems. VAV systems are standard in modern commercial buildings for their efficiency and zone control.
