AIMS AND CONTENT

LEARNING OUTCOMES

The aim of the course is provide the students the engineering knowledge on renewable energies as a whole and to the technologies and engineering methods to exploit the solar (thermal, photovoltaics) and low enthalpy geothermal resources in the high efficiency building contest. The goals of this course are to provide the students the capabilities related to modelling and design criteria definition, energy production estimation analysis, national and international standard knowledge and application, basic economic and financial investment analysis.

TEACHING METHODS

The course is based on theoretical lectures, solution of case problems and computer aided design of solar systems.
