"I wanted to take the opportunity to provide you direct comment regarding the University of Missouri – Midwest Industrial Assessment Center (MIAC) and the professionalism, exemplary assessment work and collaborative teamwork results conducted by Sanjeev Khanna, PhD and his staff at the Gateway Aluminum plant. I and the Packaging Matters and Gateway Aluminum management staff were very impressed with the knowledge, identified energy efficiency opportunities and recommended path forward provided by Dr. Khanna and staff. It was clearly evident why the MIAC is recognized as a top entity in the US Department of Energy – Industrial Assessment Center structure. We look forward to working with the MIAC on the next steps in implementing the assessment recommendations."

"Overall, the IAC Team from UMOC was very useful to us. In addition to the line items identified, having the IAC report gave us a platform to discuss our sustainability projects. As a result, we are now have a vendor coming to cost out upgrading our HVAC system. Our team has also become more aware of energy savings opportunities. For example, one recommendation was to look at the set point of the compressed air system. We learned that we need to put more focus on fixing air leaks (using a program we have in place) thus enabling us to lower the overall set point."

"IAC and the DOE have been critical to help ensure the continued success of local manufacturing by ensuring continued improvement for facilities and utility consumption. Avail Switchgear Systems is proud to have them as partners and aims to continue that partnership to provide a more sustainable business for our local community. The impact of the assessment and involvement from IAC and DOE at our facility is sending ripples of communication for other improvement initiatives and suggestions that help spark further advancement. In terms of the IAC Students, we heavily enjoyed the personnel present at the facility would highly welcome any expressed interest in any positions or potential internships in the future."

"Thank you for you and your students’ work on this report. We have a few new leadership roles at White River that are keen on reducing energy consumption at the plant and supporting creative solutions. Even if we did not complete the entire recommendation list this year, we will definitely reference the report in years to come."

"Thank you for bringing the students and performing the study. The ideas your team presented helped us to take a deeper dive on what we do for large scale projects. The return on investment was very helpful when determining what projects we would look at doing first."

"Thank you, Sanjeev. Like the report with the equations listed."

"This report has been very comprehensive and an interesting read on my part as one of the suggestions was hydropower that I have not heard about at a Wastewater Treatment Facility. I am very impressed with the report."

"I want to thank you and your team for the time you spent on this. You have been very helpful in identifying issues for us to work on. The projects we have going on currently all have energy savings in mind and we have seen a reduced load in our electrical."

"Dear Dr. Khanna, Your recommendations were greatly appreciated. 1. While not all are completed, most them have at least been initiated. 2. Reasons we haven’t accomplished more on your recommendations: a. We’ve grown our sales an average of 15% each of the last few years and have a plan for 35% growth in 2022. So we have a lot of priorities right now. b. We’ve navigated a pandemic that has had tremendous impact on nearly every aspect of our business. Market shifts, supply chain disruptions, rapidly changing costs…to name a few. Once again, thank you for your help and advice. Regards, Carl"

"I would like to take a moment and express my gratitude to you and your students for completing the energy audit at our manufacturing facility. Your team was polite, professional, knowledgeable, curious, safety-conscious, and resourceful in determining areas of improvement. I appreciate the feedback we received on your very detailed report. We will use it as a guide as we move forward in our efforts to reduce energy waste. I would highly recommend your group to other facilities looking to improve their processes. Your team identified issues we've had for years but have never taken a step back and realized on our own. Thank you again for the audit, detailed report, and recommendations for our facility. Job well done!"

"We felt that that the audit was very thorough when exploring energy savings for the facility. Many of the ideas had never been considered previously in our efforts to increase efficiency."

"Hi Dr. Sanjeev, Thank you for the work you and your team performed for Melton Machine & Control Company (MMCC). The assessment report for our facility was very comprehensive and outlined very specific and practical ways to save energy. Our personnel that worked with you and your team learned a lot from the process and the assessment report. Subsequent from your visit, MMCC made the decision to build a new facility and relocate. This was a large undertaking and was recently completed this year. Many the recommendations in the assessment were incorporated into the design of the new building. Some of the recommendations implemented include: a) Using a venturi nozzle instead of a compressed air nozzle in our paint booth operation, b) using occupancy sensors in all areas of the building, c) installation of a high efficiency variable air volume (VAV) HVAC system, d) incorporating the ability to redirect outside air for compressor air intake, e) the use of cog belts on motors vs. smooth v-belts, and f) increasing the A/C temperature setpoint in the manufacturing area above 72 degrees Fahrenheit. In addition, we have also been able to incorporate some of your recommendations at our 851 Vossbrink facility as well. Specifically the installation of occupancy sensors in low use areas and the replacement of smooth v-belts with cog belts. We are currently considering replacing our older HVAC units with newer models. Thanks again for performing the audit of our facility and developing the assessment report."

"Good Morning Sanjeev, Appreciate you and your team’s hard work on this. Look forward to implementing some of the items you presented. Thanks Logan "

"Thank you , this is great work."

"Jan. 7, 2020: Working with Sanjeev and his students was nothing short of professional and educating. From the first interaction with the students you could tell that there was real interest in the work that they were doing. The areas that they indicated improvements and the estimated cost savings made it really easy to justify the costs of the upgrades. I would highly recommend this group to any company or cooperation looking to modernize and become more efficient with the energy they consume. March 29, 2019: I have printed and briefly went through the review. This is a great amount of work and am excited to thoroughly read through this and look at how we can save money on electrical consumption as well as water. I will provide some feedback/comments after I go through it completely. Thank you very much again for the diligent work you and the students have put into this I greatly appreciate it. Best Regards, Joshua B. Youngblood Asst. Water Quality Superintendent-Wastewater"

"Sanjeev, We here at SAI would like to say “Thank You” to you and your students for the outstanding job they did evaluating our facility. They came in and got right to work, detailing out every aspect of our energy and utility usage. The final report that was generated was very detailed and gave us some great ideas to reduce costs and emissions in our facility. This type of practical hands on experience is a great learning tool for the students and it also gives us another set of eyes looking at the processes and generating new ideas. We have already started the process of implementing some of these cost saving ideas into our facility. We appreciate all your time and effort the students put forward on this project. "

"Thank you Sanjeev! I have been going through the report. It is very comprehensive! The audit team from University of Missouri Columbia did a fantastic job of learning our operation and identifying some key projects for our facility to become more sustainable. The knowledge they bring is invaluable. Although some of the projects identified have not been completed to date, they are still being investigated for costs versus budget available to implement. I really enjoyed working with them and would recommend their services to anyone interested in sustainability and reducing your carbon footprint."

"Sanjeev, This audit is very well done. Not only does it provide Dean Foods with sustainability projects and the savings calculations use for project justification, it also provided your students with real world hands-on experience. I support the O’Fallon plant from a corporate engineering function, so when Randy presented your idea to perform the audit I thought it was a great fit with our sustainability objectives. Dean Foods, like many organizations today, is being asked to dig deeper for sustainability and cost savings projects, so this audit will allow us to fill the pipeline. Randy and I will get together to look over the projects and discuss possible timelines for completion. Thanks again for teams work. "

"Thank you and your professional students for the collaborative time auditing and understanding our facility which provided excellent assessment recommendations in which to reduce operating cost and the subsequent CO2 emissions. I would be interested in a follow up that shows expected annual savings from what we have done or expect to complete by year end."

"This is a very comprehensive energy report. Very well stated through careful engineering calculations. I am glad to see that all data used were true and within range. Savings calculated are realistic and initial cost were low. Bottom line is, I like your approach of evaluating what we have and figuring out how to manage the equipment to yield higher throughput in relation to operating cost before any expensive upgrade implementations. (by Khanna: this comment relates to the battery cooling AR #9, I had suggested that they should first conduct an experiment on a small table that mimics their larger scale production) I truly appreciate the effort and hard work of you and your team. I assure you that most of these, if not all, recommendations will be implemented in our facility and perhaps to all JCI plant across NA. Moving forward, my team will develop an action plan to start implementing these recommendations. I will definitely call you if we have some questions. Thanks for the help. Please extent my appreciation to your team. "

"Received July 1, 2019: Sanjeev, Attached is a summary of our electric usage over the last two and a half years. We implemented several recommendations from the energy audit during June of 2018. As you can see, the savings have been material. Thank you for your help with our energy issues. We would like to continue to work with you on these type of programs in the future. Peter Hofherr --------------------------------------------------------------------- Sanjeev, We are very appreciative of your work with the students on the audit. I thought the team did a great job! We are actively putting together the financing packages for several of the recommendations. Many of the projects are part of our overall sustainability initiative on campus. We would love to continue the relationship as we are always trying to figure out how to do what we do better and more efficiency. If you see opportunities in the future to work with together, will you reach out? Regards, "

"Working with Sanjeev’s team was a delight. They were knowledgeable, professional and asked great questions to understand our process completely before generating a report with suggestions. The report highlighted some improvement areas that we had not thought of yet which was fantastic. Thank you very much for your time to help us continuously improve our energy reduction plans."

"The report looks great! Very detailed and payback calculations make it easy for our team to prioritize. We are planning to discuss it tomorrow in our weekly management meeting and come up with an action plan to start getting some of the improvements underway. I will let you know how things progress. It has been a real pleasure working with you and your team. "

"The audit process is valuable to help understand the highest areas of benefit and to allow us to get a outside perspective on the projects we should focus on. We have been able to start projects earlier by having the energy savings to justify the projects. "

"In relation to our audit, we also recommended to the company for a MoIAC student internship to follow up with the implementation of the recommendations. As a result, Austin Laramie, a MoIAC student and at the time also enrolled in Bin Wu’s “Industrial Energy Efficiency and Management (MU IMSE 4580)” class, was employed during the summer by the company: According to the company: “ (the MoIAC student) helped to go through the details of every recommendation on the list. This worked great!” From the student (Sep 25, 2017): "Dr. Wu, The IAC program I was involved in was fantastic experience in a very important area of Industrial Engineering. Learning how to directly identify improvement areas in energy efficiency in a factory was great knowledge that can be used generally wherever my degree takes me in industry. Any time I walk into a new manufacturing facility I can immediately recognize energy that is being wasted or can be more efficiently utilized in the plant. Helping organize reports on the recommendations were also great practical application to showing upper-level management how the energy-savings investment is worth while based on a simple payback period from predicted utility bill savings. Your classes helped me grasp a deeper connection with how all of the units in energy efficiency come together to make calculations a breeze. Before taking your class I was clueless on the difference between a kilowatt and a lumen but now I could present these to a class of my own from all the practical experience and practice. Lastly, I can't thank you enough for helping me connect with Hunter Engineering Company which gave me a paid summer internship experience focusing directly on the subjects we talked about in class and did in IAC. From the start of the summer, I had no problems talking to my boss about lighting, air-conditioning, pneumatic, or other systems that was costing the company thousands of dollars in utility bills per year. I had the chance to represent multiple options for energy-saving improvements to their facility and exactly how much they were projected to save from each opportunity. Overall, the IAC program, your classes, and my internship with Hunter Engineering have all dramatically helped my professional industrial engineering skills to make me a better asset for companies in the future. I cannot thank you enough for your patience and believing in all my potential. Hope to see you soon, Austin Laramie Industrial & Manufacturing Systems Engineering University of Missouri - Columbia""

""Your visit and report provided us with motivation and budget information to help us get these done. Thanks you very much for the work you've done.""

""Such a wonderful opportunity - you can use me as a reference anytime!" "Dr. Wu, Thank you for the follow up to the audit you and the students performed last year. I found the observations very insightful and relevant to our manufacturing operation. It was extremely helpful to learn how to quantify the savings. It is easy to overlook and avoid making the investments until you place a value on what it costs you in energy costs. Though we are unable to implement some of the items we've taken the first steps with trading out the light fixtures throughout the facility as suggested by your audit team. Best regards, Drew Dubray General Manger Koken Manufacturing""

""Thank you very much for this report. ... I am quite impressed with the comprehensiveness of your study and recommended actions. I will be sure we get our team involved with evaluating this report and taking actions to improve our energy usage performance. ... Thanks again" (March 9, 2016). "The work you carried out was so relevant and useful, that it has inspired me to initiate a internship program here at our company." (April 6, 2017)."

"Positronics Industries, Inc, has greatly benefited from the relationship that has developed with the IAC. The energy audit and assessment in which the IAC performed at our three Missouri facilities is part of our continuous improvement process of reducing and maximizing the energy used at these facilities. The audits have made us look at the feasibility of installing LED lighting, energy efficiency motors, and evaluating HVAC systems just to mention a few areas. The resulting cost savings can then be invested into the company. Having a relationship with the IAC provides Positronics Industries an additional partner in the journey down the path of sustainability and environmental stewardship. Another benefit is the information and techniques from the energy audits performed can be used to assess our other global divisions. This is a win-win situation. "

""Hi Dr. Wu, Thank you for putting this together. We appreciate the time you and your team spent on this. We will review and get back to you with any questions and I will see if I can involve any other sites. Thanks again," Also feedback from one of the MoIAC student team member (Jeff Hoiday): "... I first want to thank you for introducing me into the world of energy efficiency and sustainable energy. The opportunity that you (IAC) provided was one that would change my outlook on the ever bearing question of what I want to do when I graduate. You opened the door for me to finally answer that question.""

""Thank you so very much - this is an eye opener in many areas and I'm sure we will be able to use many of the recommendations going forward. We appreciate your willingness to do this for our company." Also, the following was sent by a IAC student (on 10/6/2015) team member who was involved in this and the other audits: "I just submitted my application for the IAC certificate request form, and I can not thank you enough for all that you have done for our IAC family the past few years. .. (the) energy efficiency class and being a part of the IAC team have truly been the most rewarding experiences of my college career. As I prepare to graduate in December, I look forward to taking everything ... about energy efficiency and apply it to the real world and be able to make a real impact wherever I end up. Being part of your team has been an amazing experience and more valuable than I can put into words. Thank you again for getting me involved with such a great opportunity. Nick Cain""
