February 2017 ASHRAE Meeting Notice  

Subject: Upcoming Department of Energy Fan Efficiency Regulations

Date: Tuesday, February 21st, 2017 

Speaker: Trinity Persful, Twin Cities Fan Companies, Ltd. 

Speaker Biography:

Trinity Persful was a member of the DOE rulemaking negotiations for the fan industry. He also is
the chairman of the Air Movement and Controls (AMCA) System Efficiency Task Force. Trinity
Persful serves as the Marketing Director and Energy Initiatives Director at Twin City Fan
Companies Ltd.


Fans consume 18% of the electricity purchased by industrial and commercial buildings. Yet, fan
efficiency has escaped the attention of most who endeavor to design efficiency into the air
systems they specify. That is about to change. The U.S. Department of Energy (DOE) will
publish their proposed rule this year covering fans from 1 to 200 horsepower. This presentation
will cover the key points to the new regulations and introduce a new fan efficiency metric called
the “Fan Efficiency Index” (FEI). The proposed DOE standard will establish a maximum power
input that will vary by a formula tied to the design point flow and pressure.
