than 1 bhp. The more stringent FEG71 was selected because the IGCC is a “reach code,” which is adopted by jurisdictions wanting construction speciﬁcations that are stricter than prevailing codes and standards. As with Addendum u to ASHRAE 90.1, the code change proposal included a speciﬁcation that the fan design point of operation must be within 10 percentage points of the maximum total efﬁciency of the fan. The change proposal revised Section 607.2.2.3 within the prescriptive provisions of the code, which apply to buildings up to 25,000 sq ft. This represents a signiﬁcant opportunity for adoption of a fan efﬁciency grade minimum because, according to the 2003 Commercial Building Energy and Characteristics Survey administered by the Energy Information Administration, almost 90% of the U.S. commercial building stock is 25,000 sq ft or smaller. Larger buildings are required to use the performance path of the code to demonstrate whole-building compliance and will not have a fan efﬁciency requirement.

The ﬁnal outcome of the code change proposal remains in ﬂux. Comments to the International Code Council are due by August 12. The ﬁnal outcome and adoption (or rejection) of this Code requirement will be determined at the ﬁnal action hearings in early November 2011. Conclusion Organizations that develop energy codes and standards are fervently to ﬁnd innovative ways to decrease energy consumption in buildings as expeditiously and cost effectively as possible. One way is to increase fan efﬁciency; AMCA Standard 205 is now positioned to assist in setting and meeting fan efﬁciency goals. AMCA’s website, www.amca.org/feg, will provide regular updates on the progress of ASHRAE 90.1 Addendum u, the International Green Construction Code change proposal, and other code/standard actions affecting air-system energy efﬁciency.
