The American Society of Agricultural and Biological Engineers has revised an existing standard on selecting energy efficient ventilation fans for agricultural use.

Information in the newly published document, ASAE EP566.1, Guidelines for Selection of Energy Efficient Agricultural Ventilation Fans, will help lower agricultural production costs by increasing energy efficiency of agricultural ventilation fans.  

The University of Illinois Bioenvironmental and Structural Systems Laboratory and other sources provided the data used to improve the effectiveness of this standard.

Copies of the document can be ordered by contacting ASABE headquarters directly by e-mailing: A free electronic copy of the standard also is available to ASABE members and those with site-license privileges to ASABE.

ASABE is recognized worldwide as a standards developing organization for food, agricultural, and biological systems, with more than 225 standards currently in publication. Conformance to ASABE standards is voluntary, except where required by state, provincial, or other governmental requirements, and the documents are developed by consensus in accordance with procedures approved by the American National Standards Institute. For information on this or any other ASABE standard, contact Scott Cedarquist at ASABE, (269) 429-0300, e-mail
