This white paper introduces and describes the fan efficiency ratio (FER), an energy efficiency metric developed by AMCA International. This metric is a ratio of the actual fan efficiency to a baseline fan efficiency, both calculated at a given airflow and pressure point. The FER was designed to encourage responsible application of fans and drive significant and quantifiable energy savings through energy codes, utility rebate programs and federal regulations.
