The aim of this work is to carry out a sustainability study in five campuses of the Universitat Politècnica de Catalunya BarcelonaTech (UPC) around Catalunya, i.e. Campus North and South Campuses in Barcelona city, Campus Baix Llobregat, Campus Manresa and Campus Vilanova i la Geltrú. The amount of consumed energy included in the study for each campus corresponds to monitoring data of previous periods. The study analyses the expected energy production, as well as the self-consumption that can be achieved by using photovoltaic (PV) systems of 25, 50 and 100 kWp and c-Si, Poly or CdTe Technology in order to reduce the environmental impact in each campus. An economic analysis of all the proposed facilities was conducted to examine their financial feasibility.
