Dalkin McQuay meets DOE's rooftop unit challenge

Dalkin McQuay, competing with four other manufacturers, was the first to complete the DOE's challenge, which is designed to help save energy by as much as 50% in buildings.


The Dept. of Energy has announced Daikin McQuay's Rebel rooftop unit system is the first to meet DOE's Rooftop Unit (RTU) Challenge. Five manufacturers—Daikin McQuay, Carrier, Lennox, 7AC Technologies, and Rheem—are participating in this challenge to commercialize highly efficient commercial air conditioners that satisfy a DOE-issued specification for energy savings and performance. When built to meet the specification, these units are expected to reduce energy use by as much as 50%, relative to units built to current standards. Nationwide, if all 10- to 20-ton RTUs met the specification, businesses would save more than $1 billion each year in energy costs. The five companies have until April 1, 2013, to submit a product for independent evaluation according to the specification.

The Energy Department is evaluating potential demonstration sites for high-performing products that meet the RTU Challenge and is also developing analytical tools that enable businesses to more accurately estimate the energy and cost savings of using high-performance RTUs in their facilities. The specification for the RTU Challenge, aimed at spurring the market introduction of cost-effective, high-performance commercial RTU air conditioners, was developed by DOE technical experts and informed by industry partners.

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.
