Air curtains approved as alternative to vestibules
The 2015 version of the International Energy Conservation Code will approve air curtains as an alternative to vestibules.
Air Movement and Control Association International Inc. (AMCA International) announced that the 2015 version of the International Energy Conservation Code (IECC) will contain a provision enabling air curtains to be considered as an alternative to vestibules. For compliance, air curtains have to be tested in accordance with ANSI/AMCA Standard 220, and be installed in accordance with manufacturer's instructions. The IECC is published by the International Code Council.
Air curtains are devices installed above exterior door thresholds that blow a film (curtain) of air downward when the door is opened, trapping conditioned air inside the building.
"The IECC provision complements a similar provision adopted by the 2012 International Green Construction Code. Taken together, air curtains can help meet baseline energy codes and green construction codes," said Brian Jones, Engineering Manager, Powered Aire, Inc., Greenville Penn., and chair of the AMCA Air Curtain Engineering Committee.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
