considering this single point, the metric establishes a restricted
speed range while remaining consistent with its use at the
design point of operation. As shown in Figure 3, the restricted
speed size is the maximum speed at which the fan can be
operated to remain at FEI = 1.0 or greater.
While driving significant energy savings and technological
improvements, the FEI will also teach proper fan selection.
Every detail that helps a consumer make a fan selection decision
will show the value of FEI for that selection. Consumers will
know immediately how their fan selection compares to the
maximum baseline fan electrical input power. They will know
how the energy consumption of one product compares to another,
regardless of product type, category, size or drive method.1

regulatory framework will soon show itself in standards,
codes and regulations.
FEI is a metric that allows many different types of fans to
be compared on equal footing, and it does so by concentrating
on the energy consumed by a fan as it is applied. It can be
used by regulators and purchasers alike to make a price-sensitive
market favor true efficiency, helping consumers see how a fan
can be affordable and efficient at the same time. Additionally,
the FEI can provide manufacturers with concrete assurance
they are creating energy saving products that will appeal to
their customers. It is an all-encompassing, high-level solution
to a complex problem.

CONCLUSION

FEI was selected by the DOE, AMCA and other industry
stakeholders to be the metric around which a federal efficiency standard would be developed, and it can be applied
in rebate programs for commercial and industrial fans. The
long, hard work that has gone into the development of this
sophisticated and effective metric and the supporting
