The Air Movement and Control Association (AMCA) welcomed 90 individuals to San Antonio for the inaugural Air System Engineering and Technology (ASET) Conference-US (ASET-US).
Held at the Hyatt Regency San Antonio Riverwalk hotel, March 6-7, the conference featured David Sellers, P.E., senior engineer at Facility Dynamics Engineering, who shared lessons commissioning taught him about mentoring and building design.
The technical program was divided into two tracks — air-systems design and air products and technologies — with attendees free to attend sessions across tracks.
In the air-systems design track:
• Stephen Wiggins, P.E., associate partner, Newcomb & Boyd, discussed ways to cost-effectively reduce static pressure, system leakage, and energy waste in existing air systems.
• Dan Int-Hout, chief engineer, Krueger, explained how to design overhead air-distribution systems that meet the requirements of ANSI/ASHRAE Standard 55, Thermal Environmental Conditions for Human Occupancy; ANSI/ASHRAE Standard 62.1, Ventilation for Acceptable Indoor Air Quality; and ANSI/ASHRAE/IES 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings.
• Jeff Boldt, P.E., LEED AP, HBDP, principal and director of innovation and quality, IMEG Corp., shared ways to attain and document compliance with fan energy requirements in ANSI/ASHRAE/IES 90.1 and the International Energy Conservation Code.
• Steven T. Taylor, P.E., principal, Taylor Engineering, provided expert tips for the design of variable-air-volume ducted air systems.
• Ron Wroblewski, P.E., president, Productive Energy Solutions, provided guidance on assessing fan performance in the field and troubleshooting fans.
• Michael Ivanovich, senior director of industry relations, and Josh Parent, associate director - technical advisor, AMCA International, discussed the AMCA Certified Ratings Program and how to properly specify AMCA-certified products in construction documents.
In the air products and technologies track:
• Mike Wolf, P.E., director, regulatory business development, Greenheck, discussed sizing and selection of axial and centrifugal fans and explained the new Fan Energy Index (FEI) metric.
• Bill Koffel, P.E., FSPE, president, Koffel Associates, discussed the impact of compartmentalization requirements on fire- and smoke-damper design and testing.
• Jim Smardo, director of louvers and architectural systems, Ruskin, discussed sizing, selection, and specification of rain- and hurricane-resistant louvers.
• Trinity Persful, vice president of marketing, Twin City Fan & Blower, discussed advances in motor, variable-speed-drive, and belt technologies and the newly published ANSI/AMCA Standard 208, Calculation of the Fan Energy Index.
• John Sofra, U.S. markets manager - airflow, industrial, environmental, Kinetics Noise Control, discussed noise and vibration attenuation in commercial air systems.
• Mark Bublitz, vice president of engineering, and David Maletich, director of marketing, New York Blower, provided tips on minimizing system effect.
ASET-US attendees had the opportunity to earn up to seven professional-development hours.
"ASET-US provided an excellent venue for our staff to be exposed not only to air-system and fan fundamentals, but the greater expanse of air-system design," said Bublitz, who co-chaired the event with Ivanovich. "Working for a fan manufacturer, we rarely have an opportunity to become exposed to air-system design 'beyond the fan.' ASET-US assembled interesting speakers who are deeply knowledgeable about a variety of air-system components and abreast of current events, such as energy-efficiency regulation. David Sellers' plenary talk was superbly crafted and delivered. We learned much and really enjoyed learning. The experience exceeded our expectations and delivered more than the typical 'technical conference.'”
