Microgrid and building retrofit for NZEB target recognition: from convent to historical residence

Great part of the Italian buildings have historical value and it make difficult to reach high energy performances, due to the limitations introduced by the legislation to preserve their cultural impact. Therefore, in the present paper is analyzed a possible retrofit scenario for the envelope of an historical edifice and the creation of a microgrid in order to optimize the electrical energy produced by PV panels with the goal of reaching the Nearly Zero Energy Building target, despite of the boundaries limiting the possible interventions.
