Understanding the Energy Efficiency Codes Before Selecting an Inline Fan.

Energy efficiency and sustainability are no longer buzzwords in construction and manufacturing. They are now included in a wide array of codes enveloping all aspects of these businesses. If you plan on installing an inline fan, understanding the energy efficiency codes is now a priority.


Since 2010, the AMCA has published AMCA 205, Energy Efficiency Classification for Fans. Arguably, the most influential of the codes governing this sector, it has significantly affected this industry. The system is based not on the horsepower of a fan’s motor but on independent variables. It grants fans a FEG – Fan Efficiency Grade providing a standard for classifying fans in a range from minimal to optimal energy efficiency.


ASHRAE 90.1 is the standard for the minimum energy codes in buildings in the United States and globally for both design and construction. Since 2013, it has included a specific section referring to the energy efficiency of fans, including inline fans. It defines it according to the FEG in AMCA 205, Energy Efficiency Classification for Fans, of 67 or higher. The inclusion has impacted the decision of other associations in determining their standard and codes among other groups.


IgCC also has instituted a requirement for fan efficiency. It uses the FEG rating, setting the minimum rating at 71. However, it only applies to specific types of fans in structures smaller than 25,000 sq ft.
