in the United States, a summary of where the
federal and California fan regulations currently stand,
and a forecast of impending changes. Its focus is CIFB;
circulating fans are addressed in the article on Page 12.
Fan-Regulation History: Energy Codes
Around 2008, ASHRAE Technical Committee (TC) 5.1,
Fans, and the mechanical subcommittee of ASHRAE
Standing Standard Project Committee (SSPC) 90.1 were
looking to establish minimum-energy-performance standards
(MEPS) for fans. They decided on percent effi ciency

n developments called " the most signifi cant events
... in the history of the industry, " 1 the U.S. Department
of Energy (DOE) published a test procedure2 and
the California Energy Commission (CEC) approved an
effi ciency regulation3 for commercial and industrial fans
and blowers (CIFB), both of which took effect in 2023,
with, as of this writing, a compliance deadline of Oct.
30, 2023, for the former and Nov. 16, 2023, for the latter.
The road to regulation has been long-12 years-and
winding, with changing metrics, standards, energy-code
provisions, manufacturer software, and more. The good
news is this period of regulatory development is nearing
an end; the bad news is there are several more years of
" hysteresis " before the regulations are stable.

Three main categories of fans are regulated.
As defi ned by the U.S. Department of Energy,
they are:
■
Large-diameter ceiling fan-a ceiling fan with
a blade span larger than 7 ft (2.1 m).
■
Circulating fan that is not a ceiling fan-an
air-circulating fan head or other type of circulating
fan that is not a ceiling fan that has
an electrical input power of 125 W or more.
■
Commercial or industrial fan or blower: A
rotary-bladed machine used to convert electrical
or mechanical power to air power, with
an energy output limited to 25 kJ/kg of air.
It consists of an impeller, a shaft, bearings
and/or a driver supporting the impeller, and a
structure or housing. It may include a transmission,
a driver, and/or a motor controller.
