AMCA 206-15 - Fan Efficiency Grade Application Guide

The fan efficiency grade (FEG) is an energy metric that describes the quality of energy transformation of a fan. The FEG metric is designed for establishing minimum fan energy efficiency requirements by regulatory bodies, code agencies and advocacy groups. The metric offers a simple means to identify the level of energy transformation in ducted air systems. This document provides an overview of issues associated with fan energy consumption and offers guidance for using the FEG in codes, standards and regulations as a means to increase the use of energy efficient fans.
