Subject fundamentals
The purpose of this course is to provide the main concepts concerning the efficient use and production of energy in the industrial sector. In the first part of the course the actual energy-sector regulations are discussed and the incentives for energy savings and for the renewable energy production are presented.
In the second part, the theme of industrial energy audits is discussed, showing how to discover energy loss areas, how to improve production processes upgrading or replacing equipment and also showing how to determine the cost, return on investment and payback period for different kinds of projects.
Finally industrial applications of cogeneration and trigeneration are studied and assessed in comparison with more traditional systems of electrical end thermal energy production.
Expected learning outcomes
The course provides the students with the ability to carry out analysis of the stream of different energies which are transformed inside any industrial process. Moreover he will learn how to perform technical and economical evaluations of cogeneration plants, energysaving investments and feasibility studies and financing.
Prerequisites / Assumed knowledge
Preliminary knowledge acquired in the courses of Hydraulic, Thermal Machines Fundamentals, Thermodynamics and Thermo-kinetics.

Assessment and grading criteria
The exam consists of a written test on practical problems and theory. The test duration is approximately 2 hours: usually three questions about theory issues have to be discussed in one hour by the student, than one hour is devoted to solve one problem. Each theory question/problem worth 25% of the final mark.
