Large-scale evaluation of the suitability of buildings for photovoltaic integration: Case study in Greater Geneva

In the context of a rapid and massive deployment or renewable energy in particular solar photovoltaic, it is necessary to develop methods tools guide this deployment. To end, work proposes multicriteria approach for evaluating suitability building be equipped with photovoltaic (PV) systems (PV suitability). present case, technical (roof complexity), economic (payback period), environmental (CO2 reduction), energetic (self-consumption), as well social (heritage constraint) criteria are considered. These evaluated each Greater Geneva Agglomeration (GGA), cross-border French–Swiss territory nearly 270 000 buildings. A method, ELECTRE TRI, makes possible sort these buildings into three categories, A, B, C, that correspond “very high,” “high,” “moderate” PV suitabilities, respectively. Large differences observed within 210 municipalities GGA since some them have almost no A-ranked whereas others comprise more than 70% It shown that, by prioritizing buildings, 50% annual electricity consumption Canton could produced systems. Finally, method developed here offers decision-aiding tool used at scale achieve transition goals terms
