Educational objectives
The main aim of this teaching is to provide students with the basis for the individuation and determination of the optima energy solutions, also from an environmental and economic point of view, for a case study. The main acquired knowledge will be:
- Basic knowledge of energy and environmental planning
- Knowledge about the world and national status of energy reserves and consumptions
- Fundamentals of environmental issues related to the use of different energy sources
- Knowledge of the main solutions for energy saving and the improvement of energy efficiency in industrial applications
- Basic knowledge on energy markets
The main competence (i.e. ability to apply the acquired knowledge) will be:
- Identification of the optima energy solutions for an applicative case, taking into account the technical, economic and environmental aspects
- Identification of appropriate energy saving solutions for industrial applications and evaluation of technical/economic convenience by energy audit
- definition of a local energy planning
Prerequisites
In order to be able to understand and apply the majority of the techniques described within the Course, you must have you must have the prerequisite knowledge of the exams of Applied Physics and Machinery, with particular reference to the technical and energy topics described in these courses.
Teaching methods
The course is organized as follows:
- Lectures on all subjects of the course;
- Classroom exercises for the depth of some topics described in the course about energy plants.

Frequency: recommended
Location: Department of Engineering, via G. Duranti, 67 , 06125 Perugia
Calendar of didactic activities: See the website of the Department of Engineering www.ing.unipg.it
Learning verification modality
The exam consists of an oral test. The oral test consists of an interview of about 30 minutes long about the theoretical contents as indicated in the program. The exam also consists of an optional group or individual in-depth work on a program topic (a feasibility study on an energy plant), whose positive outcome is evaluated as an increase of 2-3 points in the final grade. The examination, as a whole, allows to verify the ability of knowledge and understanding achieved by the student, the ability to apply the acquired skills and to display, the ability to deepen the described topics and to learn and develop solutions for independent judgment.
