AWEF / Critical DOE Information

April, 2rd, 2019


The Annual Walk-In Energy Factor (AWEF) is a regulatory efficiency metric created by the Department of Energy (DOE) that measures electrical energy input versus the cooling capacity of the system.

The DOE recently proposed and implemented a set of standards to regulate energy consumption in the United States. The law mandates every product that consumes energy should follow a set standard defined by DOE. All commercial refrigeration equipment manufacturers should comply with the Annual Walk-In Energy Factor (AWEF) rating defined by the DOE. Fundamentally, the ruling will reduce energy consumption and increase efficiency of commercial refrigeration equipment.
