Understanding Fan Efficiency Grades

Incorporated into the 2013 release of ASHRAE Standard 90.1, are new fan efficiency Grades (FEG) as defined in AMCA 205. However, selecting a fan with the highest FEG doesn't always result in the "best" fan selection. This Greenheck FEG paper will help to explain the new AMCA 205 metric, along with Greenheck's recommendations for selecting the "best" fan for the job.
