Commercial and Industrial Fan Efficiency


Length: 4 modules

Instructor: Wade Smith

Subjects: Renewable HVAC: HVAC Design


Fans account for 18% of electricity consumed in commercial and industrial buildings. That is why the U.S. Department of Energy (DOE) is introducing its regulation of fan efficiency, with a new metric called the Fan Energy Index. Take this training to master fan basics, understand the new proposed DOE regulation, and learn how to use the DOE metric to drive air moving system efficiency up. You will also learn emerging utility rebate programs that will be coming, along with fan performance monitoring tools.

This course assumes that participants have a basic understanding of commercial and industrial fans and wish to learn more about how to improve fan system efficiency, respond to DOE regulation, and consider emerging technology.
