Emergy Accounting Summer School

International School on Emergy Accounting, Venice Italy, 17-21 June 2013

The International School on Emergy Accounting is organized by the Department of Molecular Sciences and Nanosystems together with the Department of Economics of Ca’ Foscari University, and in collaboration with Parthenope University of Naples. Aimed at building unifying perspectives for effective analysis of complex systems through the concept of Emergy, it is open to PhD and postdoctoral students. In particular, it will focus on the potential of emergy accounting in problems related to sustainability, offering a unique opportunity to merge scientific and economic aspects within research.

Directors:

  • Francesco Gonella, Dept of Molecular Sciences and Nanosystems, Ca’ Foscari University, Italy
  • Sergio Ulgiati, Dept of Environmental Sciences, Parthenope University, Naples, Italy

Main lecturers:

  • Mark T. Brown, Dept of Environmental Engineering Sciences, University of Florida, Gainesville, USA
  • Sergio Ulgiati, Dept of Environmental Sciences, Parthenope University, Naples, Italy

Course Outline

Five day workshop stressing emergy concepts, theory, and principles. Each day is composed of 4 sessions, two in the morning and two in the afternoon. One or two sessions each day is devoted to a case study that includes “hands-on” computation of emergy or simulation of models to reinforce lecture material and extend understanding of systems concepts.
