"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."
