Resource description

The integration of photovoltaic (PV) systems in buildings shows several advantages comparing to conventional PV power plants. Main objectives of the present study are the quantitative evaluation of the benefits of building-integrated PV systems over their entire life-cycle and the identification of best solutions to maximize their energy efficiency and CO2 mitigation potential. In order to achieve these objectives a simplified Life Cycle Analysis (LCA) has been carried out. Results are reported in terms of several indicators: energy pay-back time, net avoided CO2 emissions, CO2 yield and specific CO2 emissions. The indicators show that the integration of PV systems in buildings clearly increases the environmental benefits of present PV technology. These benefits will further increase with future PV technologies
