c o d e w at c h Fan Efficiency Regulations: Where Are They Going? By MIChael IvanovICh, Director of Strategic Energy Initiatives, AMCA International The U.S. Department of Energy (DOE) estimates that commercial fans and blowers consume 139,533 million kWh of electricity per year and industrial fans and blowers consume 90,057 million kWh of electricity per year. In total, this amounts to 0.79 quads of energy, which is equivalent to consuming approximately 28.4 million tons of coal per year. To date, DOE has not regulated the energy efficiency of commercial and industrial fans and blowers, nor have model codes and standards for energy or green construction promulgated fan-efficiency requirements. But things are set to change—drastically. Since AMCA published AMCA 205 Energy Efficiency Classification for Fans in 2010, groundwork for establishing fan-efficiency requirements that began in 2007 has increased in momentum and is beginning to appear in published regulatory documents. As shown in Figure 1, beginning with the 2012 International Green Construction Code (IgCC), fan efficiency requirements are expected to appear in the next issue of the model codes and standards as follows: • 2012: International Green Construction Code • 2013: ANSI/ASHR AE/IES 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings • 2014: ANSI/ASHRAE/IES/USGBC 189.1 Design of HighPerformance, Green Buildings Except Low-Rise Residential Buildings • 2014: IAPMO Green Supplement to Uniform Mechanical Code and Uniform Plumbing Code • 2015: International Energy Conservation Code. IgCC As mentioned earlier, the 2012 IgCC fan efficiency requirement is already available to the public. For buildings 25,000 ft2 and less, stand-alone exhaust, supply, and return fans that are larger than 1 hp must have a fan efficiency grade (FEG) of 71 or more, and be selected to operate within 10 percentage points of their peak total efficiency. The 2012 IgCC references AMCA 205-10, the 2010 version of the standard. Figure 1: Timeline of national codes and standards for adding fan-efficiency specifications in national codes and standards. Also, note that the U.S. Dept. of Energy is establishing a fan-efficiency standard for regulatory purposes during the entire timeline.
