Noteworthy Feedback

"On behalf of the Timken Corporation’s Mascot, Tennessee operations team, we greatly appreciate the service provided by the Tennessee Tech Center for Manufacturing Research and the entire team that participated in the Energy Assessment. I have performed a cursory review of the report and will be excited to share with the leadership team. Going forward, we will use the assessment as our guide to help drive down costs associated with energy waste streams and practices. I welcome the thought of a return visit by the IAC in the future to perform another assessment not only to monitor how we are doing, but to provide a platform for other students to further their education while gaining valuable hands-on experience. Please reach out to any of us when that opportunity arises. Respectfully, Dick Moisan"

"I wanted to send a quick note as appreciation for the excellent assessment that TTU performed under your leadership. The level of professionalism and willingness that your group demonstrated during the past few months was outstanding. Our company is pleased with the results of the assessment and for the recommendations to improve our energy consumption. It will help our site to achieve targeted cost savings and energy conservation KPI’s. This assessment will be used as a reference to implement similar studies in our sister sites within North America region. Please extend my recognition to the students that participated, they were very professional and supportive."

"This communication is to express our appreciation for making us aware of the assessment help available from the US Department of Energy through your group at the University of Memphis. The free services you provided yielded some great recommendations. Some of these we’ve already working on, some we can enact now, and others we will continue to look at to take advantage. The information provided in the study presented was very informative and was supported well with the data collected and analyzed by your team. While we understand there are thing we must improve to reduce energy cost, it was exciting to hear we are currently in the “Gold Standard” area regarding the air loss/leak portion of the study. Again, we appreciate the time and effort it took for your team to collect, compile and present such a thorough study that will be a benefit to us in our efforts to reduce energy usage."

"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!"

"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."

"â€œThe benefits we felt by working together with Tennessee Techâ€™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.â€ "

"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.""
