The decentralized solar deployment will play a crucial role in the energy transition, especially in urban areas where high electricity consumption density is found. By implementing local generation systems, such as photovoltaic panels in buildings’ roofs, energy communities (EC) arise as an innovative and cooperative strategy to share these decentralized energy resources. This work develops a modeling framework to assess the potential of EC creation, by combining Urban Buildings Energy Modelling (UBEM) capabilities and building’s rooftops potential for solar generation. Hence, three EC case studies, with multiple building typologies, have been simulated and analyzed for three energy sharing scenarios: individual self-consumption outside an EC and collective self-consumption without and with a central battery storage, both inside an EC. The case study results demonstrate that self-sufficiency in buildings increases when going from individual self-consumption to collective self-consumption, having the best results when combining diverse demand profiles. Self-sufficiencies achieved at a community level range from 16% to 34%. Moreover, results show that when considering battery storage systems, self-sufficiency increases 16 percentual points, however decreasing the economic viability. By considering UBEM outputs the developed model allowed a valuable assessment of EC performance, constituting a valuable step in enhancing its implementation.
