Noteworthy Feedback
""You guys did an awesome job and I was totally impressed with the energy team." - Tim Brown "I want to thank you again for the effort you and your team displayed yesterday at our facility. It is refreshing to see young minds at work and eager to please. They did an outstanding job and were complimented in our 8:00 am production meeting. I have already began the process to complete the Manufacturing Tax Exempt form for Piedmont Natural Gas Company. I am looking forward to your official report from your assessment team. Please send a compliment to your team from me. Thanks again.""

"Quote from client "Please tell your group that their visit was a very successful one. It gave us the information needed to acquire some capital money to help fund the lighting program we have in place now. We are more aware of our compressed air system and have an air conditioning replacement schedule.""

"I just want to express my sincere appreciation to you and your team that worked so diligently in our facility this week. I am really pleased with the progress and the recommendations that were proposed. As you saw, we have many opportunities to enhance our energy conservation efforts and we are indebted to your team for bringing those to the forefront for us. The students were really engaged in the process and their presentations supported such. Again, thank you for your efforts and we look forward to continuing our relationship in the future. Please don’t hesitate to contact us if you ever need assistance."

"“The benefits we felt by working together with Tennessee Tech’s IAC group have been substantial. Dr. Glenn Cunningham and his team of graduate and undergraduate students brought an opportunistic attitude to our energy assessment, worked in a highly professional manner at all times and delivered a thorough analysis of our current condition, how we could improve and the potential cost savings from implementing their recommendations. We strongly encourage any eligible manufacturing site to take advantage of this program.” "

"Dr. Cunningham: I had very high expectations for this event...they were blown away and were exceeded on the upside in all aspects of this exercise. Thank you and your team for the outstanding work you performed on our behalf. We look forward to receiving your formal report and recommendations as soon as it is completed. ... I am forwarding the D.O.E./IAC program information to our two plants in Dayton and Springfield TN, along with a recommendation that they request the Tennessee Tech team for their site visit. Thanks again for your outstanding work and we look forward to your recommendations! Please forward our high praise to the rest of your team."

"On behalf of Bridgestone Warren County, thank you so much for the work the Tennessee Tech Industrial Assessment Center did at our facility to identify ways for us to reduce our energy costs. The team was very professional, and it was terrific to get some new perspectives on our processes, with some great ideas! We were happy to be part of getting the students in your program exposed to Industry applications as part of their education. Please pass our gratitude on to everyone involved in the assessment."

"The energy assessment went very well. Thank you, to all of you, for your time and attention to detail. The team has already been generating some great ideas, for savings opportunities. This was a great hands-on experience, and it was also a networking opportunity, as we offer internships... We are definitely interested in a Cybersecurity assessment! ... Thank you, Michelle, for your helping coordinate both assessments. We are so excited to partner with you!"
