PV Integration in Minor Historical Centers: Proposal of Guide-criteria in Post-earthquake Reconstruction Planning

One of the main challenges in next years will be the retrofit of existing built heritage. Even the most ancient settlements, to avoid the absolute neglect, will have to consider a "contemporary" and environmentally aware vision of refurbishment. In Italian territories hit by earthquake, this challenge is already today a potential for their life return: BIPV, or in general PV implementation, is one of the possible ways to be faced for ensuring a renewable contribution in the perspective of "Nearly-Zero Energy Settlements". The presented study, after synthesizing some main key-strategies for PV introduction at landscape, urban and building scale, focuses on the definition of reference requirements and practical findings useful in the proposal of guide-criteria for urban re-planning of minor historical centers. The outcomes could also be used in the ongoing reconstruction process, for defining innovative and sustainable strategies for PV implementation in minor (nearly-zero energy) historical centers.
