Full Description
This document defines the fan energy index (FEI), an energy efficiency metric forfans first developed by AMCA International. This metric is further defined in the U.S.Department of Energy (DOE) Term Sheet, a document approved by the DOE thatresulted from public negotiations on what a DOE-fan-efficiency regulation wouldcontain. The FEI is a ratio of the actual fan efficiency to a baseline fan efficiency,both calculated at a given airflow and pressure point. Since these efficiencies areeach calculated at the same airflow and pressure, FEI is also defined as the ratio ofthe baseline electrical power to the actual electrical power of a fan.The FEI was designed to encourage responsible application of fans and drivesignificant and quantifiable energy savings through energy codes, utility rebateprograms and federal regulations. This is accomplished by establishing theminimum fan efficiency or maximum fan input power at design airflow and pressure.
