Ceiling fans are popular for providing air mixing, destratification, and cooling effects in residential, commercial, industrial, and agricultural settings.
The U.S. Department of Energy defines large-diameter ceiling fans (LDCF) as having a blade span greater than 7 feet (2.1 meters). It's important to note that not all LDCF are high-velocity, low-speed (HVLS) fans.
DOE Actions
December 27, 2020: The Federal Omnibus Bill contained the Ceiling Fan Improvement Act from Energy Act 2020 Section 1008 changing the cfm/W regulatory metric for LDCF to Ceiling Fan Energy Index (CFEI).
May 5, 2021: A “Technical Erratum Notification” was issued by AMCA International for ANSI/AMCA Standard 230-23 with errata: Laboratory Methods of Testing Air-Circulating Fans for Rating and Certification, which is referenced in the DOE test procedure for LDCF. The erratum corrects the electrical input power measurement to standard air density.
May 7, 2021: The DOE conducts an early assessment review for the amended Energy Conservation Program: Energy Conservation Standards for Consumer Products; Early Assessment Review; Ceiling Fans. They are seeking data and input from industry stakeholders to evaluate the need to amend the standards, based on energy savings, feasibility, and economic justification.
May 27, 2021: DOE published the CFEI codification of the Ceiling Fan Improvement Act in Federal Register, thereby integrating CFEI Codification Federal Register Rules and Regulations and removing cfm/W for LDCF.
June 3, 2021: DOE extends the CFEI Codification Federal Register Rules and Regulations RFI deadline to June 28, 2021, following requests from AMCA International and the American Lighting Association, and with a letter of support from the Appliance Standards Awareness Project and the Northwest Energy Efficiency Alliance.

Certified Ratings Program
The AMCA Certified Ratings Program (CRP) was instituted to provide assurance that manufacturers’ product ratings are accurate and enable comparisons of like products across manufacturers. The AMCA CRP currently covers more than 4,000 product lines worldwide.
AMCA tests per ANSI/AMCA Standard 230-23 with errata | Laboratory Methods of Testing Air Circulating Fans for Rating and Certification and certifies LDCF ratings per AMCA Publication 211-22 (Rev. 01-23):Product Rating Manual for Fan Air Performance .
