What’s the weirdest job you’ve ever had?

On my second deployment, I once had to hook up a 20’ container for a sling load mission. I basically had to sit on top of this container while a CH-47 Chinook hovered about 5’ above the container and then hook the slings to the helicopter without becoming the middle part of a metal sandwich.

Emil De Jong

Team Lead & QAD, Southern Energy Management

Years in the building performance industry: 3

Bio: My interest in this industry started when I decided to Study Architecture at Wentworth Institute of Technology in Boston. However, after a year and a half I realized I wanted to be more involved in how buildings use and save energy. I didnt know where to start with this so I took another gap year and while working I discovered the Appropriate Technology and Building Science programs offered by Appalachian State University in Boone NC. I was immediately confident that this was for me and applied, attended, graduated and now have the pleasure of working at Southern Energy Management as the Charlotte division team lead QAD. I love helping builders and trades make smart and practical building science decisions and best of all I love showing them the fruits of those decisions in the form of low HERS® scores or energy efficient program compliance.

Where is the best place you’ve traveled to and why?

Backpacking around the Andes mountains of Bolivia, Peru, and Ecuador are some of my fondest memories.
