It is highly recommended that you apply for a course at least 6-8 weeks before the start date to guarantee there will be space available. After that date you may be placed on a waitlist. Courses with low enrollment may be cancelled up to 4 weeks before start date if sufficient enrollments are not met. If you are able to access the online application form, then registration for that particular course is still open.
The purpose of this class is to address the issues of sustainability and to expand the engineering perspective of this problem. First, we review the concept of sustainability from several points of view including economics, ecology, and business. This discussion addresses the shortcomings of several approaches including “eco-efficiency” and the “triple bottom line." We then develop a resource accounting perspective in some detail with the emphasis in four areas:
- Energy resources analysis, energy and exergy flows, balances, efficiencies, primary energy use, energy return on investment, net energy analysis, and renewable energy – all from a thermodynamic perspective.
- Material resources analysis, including not only the materials used in the delivery of products and services, but also the effects on major material cycles such as carbon, water, and nitrogen. This approach will be expanded to aggregate both fuels and non-fuel materials by using an exergy analysis approach.
- Life cycle assessment (LCA) of products and services, including variations on the method such as input-output models, hybrid models, consequential LCA and exergy methods that can incorporate ecosystem services.
- Design for sustainability accounting for the role of ecosystem services in supporting industrial activities, and an assessment of alternative sustainability solution approaches.
The class uses our book Thermodynamics and the Destruction of Resources (Cambridge University Press, 2011) and builds on these topics from a solid basis. Examples will be taken from diverse areas but with special attention to current and emerging chemical and manufacturing processes and product analysis. Participants are encouraged to bring sample cases for discussion and class will include time for hands-on LCA demonstrations.
Note: This course was previously titled "Energy, Sustainability, and Lifecycle Assessment."
Takeaways from this course include:
- Identifying alternative interpretations of sustainability, including economic, ecological, business, and resource accounting.
- Reviewing thermodynamic principles as an example of a rigorous approach to resource accounting.
- Analyzing energy transformation and materials transformation processes using various resource accounting approaches.
- Exploring life cycle assessment (LCA), including advanced LCA methods. Applying these methods to new situations and analyze products and services.

This class is intended for professionals from manufacturing, design, energy, and sustainability, as well as for academics (faculty, researchers, and graduate students).
Laptops with the ability to run openLCA are required.

Timothy Gutowski received his Ph.D. in mechanical engineering from the Massachusetts Institute of Technology in 1981. Currently he is a professor of mechanical engineering at MIT and a member of the Laboratory for Manufacturing and Productivity (LMP). He was the director of LMP from 1994 to 2004, and the associate department head for mechanical engineering from 2001 to 2005. From 1999 to 2001, he was the chairman of the National Science Foundation and Department of Energy panel on Environmentally Benign Manufacturing. He has over 150 technical publications and seven patents and patent applications. He is the editor of the book Advanced Composites Manufacturing, published by John Wiley in 1997.
Professor Gutowski’s research over the past 15 years has focused on the environmental issues associated with manufacturing including processes, products, and systems. His work on manufacturing processes is extensive, including the analysis (energy and materials) of such processes as machining; grinding, casting, forming and injection molding, advanced machining processes such as abrasive waterjet and electrical discharge machining, semiconductor and MEMS processes, nano-materials manufacturing processes, and other new technologies. In addition, he has worked extensively on recycling processes, systems, and product design for recycling, as well as on product remanufacturing and energy savings. His work also includes the energy payback analysis for new energy systems during growth, and LCA applied to personal life styles called “Environmental Life Style Analysis.”
Bhavik Bakshi received his Ph.D. in chemical engineering from the Massachusetts Institute of Technology with a minor in technology and environmental policy. Currently, he is a professor of chemical and biomolecular engineering, and civil environmental and geodetic engineering at The Ohio State University (OSU). He is also the research director of the Center for Resilience at OSU and a visiting professor at IIT, Bombay. From 2010 to 2012, he was the vice chancellor of TERI University in New Delhi, India. He has published more than 100 articles in areas such as process systems engineering, sustainability, science, and engineering.
Professor Bakshi’s research is developing systematic and scientifically rigorous methods for improving the sustainability and efficiency of engineering activities. This includes new methods for analyzing the life cycle of existing and emerging technologies and for the design of sustainable chemical processes and supply chains. A major focus of his research is on understanding and including the role of ecosystem services in industrial activities. This has resulted in the approach of ecologically-based LCA, which is available at http://resilience.osu.edu/ecolca. He continues to develop new analytic and design methods based on considering synergies and trade-offs between technological and ecological systems. Application of this techno-ecological synergy approach to biofuel life cycles and design of sustainable habitats demonstrates the challenges and opportunities of engineering within ecological constraints as a path toward sustainability.
Dusan Sekulic received his D.Sc. in mechanical engineering from the University of Belgrade, Yugoslavia, in 1982. Currently, he is a professor of mechanical engineering at the University of Kentucky, Lexington. He is a fellow of ASME and is a professor at the Harbin Institute of Technology, Harbin, PR China. He is the author of over 150 refereed research publications, more than a dozen book chapters, and the author of the book Fundamentals of Heat Exchanger Design (jointly with R.K. Shah), published by John Wiley & Sons, USA, in English, and China Machine Press, Beijing, in Chinese. He is the editor of the book Advances in Brazing: Science, Technology and Applications, Woodhead, Cambridge, UK, and editor of the Handbook of Heat Exchanger Design, Begell House, NY, USA.
Professor Sekulic’s research has been on thermodynamics aspects of energy and non-energy producing systems. His work on thermal design of heat exchangers used in these systems is extensive. His focus over the past 10 years has been on materials processing in various manufacturing processes, in particular experimental and theoretical work in the domain of molten metal wetting and spreading for materials processing related to soldering and brazing. His interest involves studies of energy and material flows in large non-energy producing systems, such as in manufacturing, with emphasis on transformational technology selection.
