AMCA Revises AMCA 205, Energy Efficiency Classification for Fans

The newest version of AMCA 205, Energy Efficiency Classification for Fans (AMCA 205-10, Rev. 2012), is now available at the AMCA bookstore for no cost. Changes made to the standard do not impact calculation of Fan Efficiency Grades as published in earlier versions of AMCA 205-10. Translations of the new version into other languages are not yet available.

The following changes were made and approved by AMCA committees in 2011 and by the Board of Directors at the Winter 2012 board meeting:

1. Replaced permissive language (can, may) with mandatory language where it was omitted.
2. Removed references to Fan Motor Efficiency Grades (FMEG) because they are not compatible with Fan Efficiency Grades (FEG) and, therefore, do not belong in one standard.
3. Removed references to static efficiency, making total efficiency the only allowed method for calculating Fan Efficiency Grades, avoiding confusion and mistakes.
4. Increased the fan-selection point to 15 percentage points from peak total efficiency (from 10 percentage points).
5. Changed the power exclusion from 125 W to 750 W (1/6 hp to 1 hp) to align requirements for fans with high-efficiency motors.
6. Added an impeller exclusion for fans under 125 mm (5 in.), as it was previously omitted.
7. Removed the exemption for circulating fans because the determination of the fan total pressure and fan total efficiency were added into the revised AMCA Standard 230.
8. Added a lower limit for FEG50, as it was previously omitted.
9. Tables A.1a and A.1b were removed because they were leading to incorrect results if used for determination of Fan Efficiency Grades by interpolation.
10. Removed Annex B – Calculation of Annual Energy Consumption.

AMCA Extending Certified Ratings Program to Include Fan-Motor Efficiency Grades

AMCA is extending its Certified Ratings Program (CRP) to cover Fan Motor Efficiency Grades (FMEGs) in accordance with ISO Standard 12759 - Fans: Efficiency Classification for Fans. FMEGs are defined in ISO 12759 as the "efficiency grade for a driven fan," which includes motors and drives. Fan efficiency grades (FEGs), which are defined in AMCA 205, apply only to the aerodynamic properties of the fan.

FMEGs are the basis of the European legislation on fan efficiency (EC 327-2011, as published in the Official Journal of the European Union), which takes effect in January 2013.

The FMEG certification program is expected to launch in 2012. For more information, contact Joe Brooks at jbrooks@amca.org.

AMCA Begins Work on Application Guide for AMCA 205

The AMCA Board of Directors approved an internal proposal to develop an application guide for AMCA 205, which is tentatively titled as AMCA Publication 206, "Application Guide for Fan Efficiency Grades." The publication, which is scheduled for completion in Fall 2012, will provide background information and application guidance on FEGs and fan-selection for improved energy efficiency.

The goals for publishing the guide are to assist various audiences in the understanding of FEGs and FMEGs as found in AMCA 205 and ISO 12759, and to accelerate AMCA 205 adoption into national and state codes/standards. The audience of the application guide includes sales/marketing/engineering staff of AMCA members; consulting engineers; construction contractors; commissioning providers; and code/standards bodies, and code officials.

The committee roster is currently being formed. If you are an AMCA member within the Air Movement Division and would like to participate, please contact Tim Orris at torris@amca.org.

AMCA Launches Energy Strategy Workshops

AMCA's first Energy Strategy Workshop was held for 39 professions in executive, sales, and marketing roles for 25 member firms on January 25-26, 2012 in Chicago following the 2012 AHR Expo. The highly interactive training sessions gave attendees strategic information and skills for navigating energy regulations, participating in energy efficiency programs, and developing internal and external marketing/communications around energy efficiency.

The distinguished panel of speakers and instructors were:

• Tom Catania, Vice President of Government Affairs (retired), Whirlpool
• Eugene Smithart, PE, Director of Systems and Solutions, Trane
• Wade Smith, Executive Director, AMCA International
• Vickie Lovell, President, InterCode Inc., and
• Michael Ivanovich, Director of Strategic Energy Initiatives, AMCA International

A second workshop has been scheduled for May 7, 8 in Chicago following the AMCA Mid-Year Meeting. If you are an AMCA member and interested in attending, please send an email message to Michael Ivanovich at mivanovich@amca.org.
