AMCA International Introduces ANSI/AMCA Standard 208-18, ‘Calculation of the Fan Energy Index’
The standard defines the calculation method for fan energy index (FEI), an energy-efficiency metric for fans inclusive of motors and drives
ARLINGTON HEIGHTS, Ill. — Air Movement and Control Association (AMCA) Intl. Inc. announced the publication of ANSI/AMCA Standard 208-18, “Calculation of the Fan Energy Index.” American National Standards Institute (ANSI)/AMCA Standard 208 defines the calculation method for fan energy index (FEI), an energy-efficiency metric for fans inclusive of motors and drives. This metric provides a standardized and consistent basis for comparing fan energy performance across fan types and sizes at a given fan duty point.
FEI has several uses. Fan specifiers can use it to understand and communicate fan-efficiency design intent, while legislative and regulatory bodies can use it to define energy-efficiency requirements of fans. The standard has been written to support the fan industry's entrance into energy and construction codes and standards and to support utility rebate programs.
