Fan Energy Index Resources

New fan-efficiency metrics developed by AMCA International—fan energy index (FEI) and fan electrical power (FEP)—can be used to right-size fans and reduce power consumption in commercial and industrial air systems. This Web page provides direct links to resources on applying FEI and FEP.

    • ASHRAE 90.1: ASHRAE 90.1: An addendum to ASHRAE Standard 90.1-2016 (Addendum ao), the model energy standard for commercial facilities, was developed to replace Fan Efficiency Grade language with FEI language. The addendum has completed public review and is awaiting final ASHRAE Standards Committee balloting as final approval toward the 2019 edition of the Standard. ASHRAE 90.1-2019 will be available at the ASHRAE Bookstore here in 2019.

    • International Energy Conservation Code (IECC): Based on ASHRAE 90.1 Addendum ao, a proposal to replace FEG language with FEI language, will be submitted by ASHRAE or AMCA International to the International Code Council for the next edition of the IECC.

     

    California Title 20 is part of the Appliance Efficiency Regulation and California Code of Regulations. It is administered by the California Energy Commission (CEC). The CEC initiated a Title 20 rulemaking for commercial and industrial fans and blowers in 2017. The public docket has all documents published by the CEC relating to the regulation, and all comments, proposals, and supplemental materials posted by stakeholders.

    • U.S. Department of Energy
      In 2011, the U.S. Department of Energy began a rulemaking process with the intent to develop test/labeling and energy-efficiency standards for commercial and industrial fans, an initiative that was put on hold in 2017. Useful materials from the initiative are the Appliance Standards and Rulemaking Federal Advisory Committee Term Sheet, which documents consensus-voted recommendations toward development of regulations, and the third Notice of Data Availability, a provisional analysis of economic impacts and energy savings that could result from promulgating a regulatory energy-conservation standard for commercial and industrial fans and blowers.
