A GIS-based model to assess buildings energy consumption and usable solar energy potential in urban areas

The described approach has been applied in two urban cells comparing the obtained results and testing its applicability in two different urban contest: a historical town centre and a new suburban district. The methodology has been proven to be suitable in both different contexts. On one hand, it has stated that new suburban districts are most suitable for solar potential exploitation, especially by means of PV. On the other hand, the obtained outcomes shows that a reduction of non-renewable thermal energy demand would have a greater impact on enhancing the buildings efficiency. The developed model should help local authorities for implementing energy management strategies in their urban areas.
