Commercial and industrial fans and blowers are used in a wide variety of applications such as commercial building HVAC systems, commercial kitchen exhaust systems, industrial processes, and agricultural ventilation.
There are currently no minimum efficiency standards for commercial and industrial fans. In 2015, a DOE-convened stakeholder working group reached consensus on a number of items related to potential test procedures and standards for commercial and industrial fans. However, DOE has not yet published a proposed rule for either test procedures or standards. In 2017, the California Energy Commission (CEC) opened a new docket to begin considering standards for fans.
The efficiency of a fan varies widely across its operating range (i.e. airflow and pressure points), and a fan with a very efficient design can perform very inefficiently if not properly applied. Therefore, improved fan selection represents a huge opportunity for energy savings. Additional opportunities for energy savings include improved aerodynamic design and more-efficient transmission, motors, and motor controllers.
