ARLINGTON HEIGHTS, Ill. — Air Movement and Control Association (AMCA) International Inc. welcomed Tim Mathson to its staff in the role of principal engineer.

Mathson, the primary developer of AMCA’s new fan-efficiency metric, fan energy index (FEI), joins AMCA after more than 30 years with a major fan manufacturer and AMCA member. His experience includes both engineering and test-laboratory management. He has been very active with AMCA, serving as chair of the Fan Committee, the U.S. Technical Advisory Group to International Organization for Standardization (ISO) Technical Committee 117, Fans, and, formerly, the committees for ANSI/AMCA Standard 210/ASHRAE Standard 51, Laboratory Methods of Testing Fans for Certified Aerodynamic Performance Rating, and ANSI/AMCA Standard 208, Calculation of the Fan Energy Index. Additionally, he is an active member of ASHRAE Technical Committee 5.1, Fans, and has presented several ASHRAE seminars.

“We’re really pleased to have Tim join AMCA’s engineering team,” AMCA Executive Director Mark Stevens said. “He’s a great fit for AMCA, and our members will feel a positive impact nearly immediately. Tim will be primarily supporting the lab, but we’ll be tapping him for ISO and ASHRAE representation, advocacy, and training.”
