Abstract: In efforts to understand ecological systems and
environmental impact, techniques can be used which combine thermodynamics
with environmental and ecological disciplines. Most such assessments
consider thermodynamics in terms of energy, but it is believed by many that
ecological and environmental factors are better understood using the
thermodynamic quantity exergy. One rationale for this statement is that
exergy, but not energy, is often a measure of the potential for ecological
and environmental impact.
Here, a summary is presented of existing analysis techniques which
integrate exergy and ecological and environmental factors, including exergy-based
ecological indicators, exergy-based life cycle analysis and environomics.
The goals of most such analysis techniques include improving our
understanding of the impact on ecological systems and the environment of
processes and the determination of appropriate ecological and environmental
improvement measures. Several examples are considered, including the
application of exergy to water-based ecosystems for understanding,
predicting and improving their health. Thermodynamic, ecological and
environmental data are examined, and show that correlations exist between
exergy and environmental and ecological parameters. The existence of such
correlations likely implies that exergy factors into environmental
improvement and ecological stewardship.
Brief biography of the speaker:
Dr. Marc A. Rosen is a Professor of Mechanical Engineering at the University
of Ontario Institute of Technology in Oshawa, Canada, where he served as
founding Dean of the Faculty of Engineering and Applied Science from 2002 to
2008. Dr. Rosen became President of the Engineering Institute of Canada in
2008. He was President of the Canadian Society for Mechanical Engineering
from 2002 to 2004, and is a registered Professional Engineer in Ontario.
With over 60 research grants and contracts and 500 technical publications,
Dr. Rosen is an active teacher and researcher in thermodynamics, energy
technology (including cogeneration, district energy, thermal storage and
renewable energy), and the environmental impact of energy and industrial
systems. Much of his research has been carried out for industry.
Dr. Rosen has worked for such organizations as Imatra Power Company in
Finland, Argonne National Laboratory near Chicago, and the Institute for
Hydrogen Systems near Toronto. He was also a professor in the Department of
Mechanical, Aerospace and Industrial Engineering at Ryerson University in
Toronto, Canada for 16 years. While there, Dr. Rosen served as department
Chair and Director of the School of Aerospace Engineering.
Dr. Rosen has received numerous awards and honours, including an Award of
Excellence in Research and Technology Development from the Ontario Ministry
of Environment and Energy, the Engineering Institute of Canada’s Smith Medal
for achievement in the development of Canada, and the Canadian Society for
Mechanical Engineering’s Angus Medal for outstanding contributions to the
management and practice of mechanical engineering. He is a Fellow of the
Engineering Institute of Canada, the Canadian Academy of Engineering, the
Canadian Society for Mechanical Engineering, the American Society of
Mechanical Engineers and the International Energy Foundation.
