Energy efficiency

Tell me your story on how you designed an energy-efficient building engineering system.


According to a recent survey we concluded of engineers like yourself, energy efficiency ranks at the top of challenges you face in engineering design. That’s not surprising—building owners want to squeeze every dollar out of their mechanical or electrical system, so they’re turning to engineers like you.

Here’s the million dollar question: What’s the best way to design energy-efficient building engineering systems? Sure, there are lots of products out there that offer savings in power usage, or more efficient water usage, or efficient lighting design, or better IAQ. But how do you design an entire energy-efficient building, and replicate that in various types of buildings?

I’d like to hear the stories or case studies of how you created the most energy-efficient design for a new building, or how you retrofitted an existing building to be efficient. Send them to me at

Please don’t include information about the specific products you used, or that you achieved a certain U.S. Green Building Council LEED status. I want to hear how you overcame a challenge, what you’re proud of, and cutting-edge system design.

Tell me about your insights into the building occupants’ energy consumption. Let me know what tools or tricks you used to keep track of the building’s energy efficiency. And finally, if you have your crystal ball handy, let me know where you think this trend is going.

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.
