the 2014 IAPMO Green Supplement. Proposals are in the
works for ANSI/ASHRAE/IES/USGBC Standard 189.1 and
California Title 24.
Development of the U.S. Dept. of Energy’s fan efficiency
standard is just beginning; the Framework Document was
published in the Federal Register on Feb. 1, 2013, which
presents DOE’s perspective of the fan market and the options it is considering for regulating commercial and industrial fans.12 AMCA International is working with ACEEE,
the Appliance Standards Awareness Project, and other organizations to jointly develop a proposal to DOE for the efficiency requirement and testing standards. Based on bestavailable information, a DOE requirement could be in place
with enforcement between 2018 and 2020. To follow developments in fan efficiency codes, standards, and regulations,
visit www.amca.org/feg.

Conclusion
The insertion of a fan efficiency requirement into
ASHRAE Standard 90.1-2013 is significant because it will
have HVAC designers, contractors, commissioning providers, code officials, and facility owners/operators thinking
explicitly about fan efficiency grades and sizing/selection

practice on a large scale. This scale is expected to grow
as fan efficiency requirements make their way into the
IECC, and ASHRAE Standard 189.1. The work done by
ASHRAE’s committees and subcommittees, and those of
AMCA International, has helped set the stage for a DOE
fan efficiency regulation.
