Mark Hydeman, PE, Principal from Taylor Engineering will present key results from the NBI PIER research on built-up VAV systems for which he was the Principal Investigator.  These include the potential for supply pressure reset for energy savings and to prevent operation in surge; a new way of modeling fan performance; and an optimized approach for selecting and controlling VAV boxes.  The project produced a design guide on air-side VAV systems that is available from the CEC website at http://www.energy.ca.gov/reports/2003-11-17_500-03-082_A-11.PDF a new model for the evaluation of fan system design and controls and a series of recommended changes for ARI Standard 880.
