This report documents the results of a study conducted to quantify potential energy savings provided by different flow-modulation methods and fan-control strategies. Results showed that variable-air-volume(VAV) systems have substantial amounts of energy in buildings with large internal loads and considered to be core-dominated. Trends noted were shifting of fractional flows downward for warmer climates and envelope-dominated buildings. Thus, the greatest savings for VAV systems occur in envelope-dominated buildings in cooler climates. The economics decision to install frequency converters or inlet vanes should be based on individual building and climate characteristics. However, noise levels and maintenance factors should also be considered.
