HVAC designers choosing variable air volume (VAV) systems have several options for modulating the flow. Some of the more popular methods for centrifugal fans are discharge dampers, inlet vanes, and motor speed control. This paper describes a study in which these different methods of fan modulation are compared for two prototypical buildings in five locations in the United States. The tool used to compare the methods is the Building Loads Analysis and System Thermodynamics (BLAST) program. In addition, factors affecting the results are also examined. In particular, a detailed examination of the annual building load distribution is made.
