Sampling of building surfaces towards an early assessment of BIPV potential in urban contexts

Marilyne Andersen, Giuseppe Peronato

Although the integration of PV systems in the building envelope (BIPV) is an important factor for the acceptability of such installations, current urban-scale solar potential metrics only partially consider this aspect. As part of the definition of BIPV-su ...
