“Fan Efficiency Grades” by Jay Eldridge

This presentation provides an update on the Fan Efficiency Grades (FEGs) that are included in ASHRAE 90.1-2013, mainly what are they, and how will they affect an engineer’s fan selection.  The presentation will also include pointers on optimizing fans selections for low energy use and complying with 90.1.

 About the Speaker:
Jay Eldridge is the Applied Air Systems Development Manager for Daikin Applied. He has 25 years experience in the application and design of applied HVAC systems. His current responsibilities include optimizing and working with applied air sytems, but he has an extensive background in chiller and heat pump systems.

Jay is an ASHRAE member and served as the chair of the District Energy (TC 6.2) technical committee and is a member of the Large Building Air-Conditioning Systems (TC 9.01)  committee. He is also a corresponding member of the Fans technical committee (TC 5.1). Jay has a degress in Mechanical Engineering from Iowa State University.


“System Pressure Calculations for Proper Fan Sizing and TAB Report Correlation”  by Jerry Williams

This presentation will build on the topic of maximizing fan efficiency by considering both the fan and the system it is integrated into. The presentation will include a review of the total pressure calculations needed to establish the required fan performance, selecting the correct fan from a fan industry grounded in fan static pressure ratings, a review of the role of system effect factors in fan system sizing and design, and finally how a testing and balancing report should acknowledge and describe fan system effects encountered.
