"Energy castles" equalized to strategic structures for disaster recovery in emergency
Rural and marginal areas with a low density of buildings and facilities have generally an easily vulnerable service continuity. The earthquake of central Italy in the beginning of 20017 has claimed the need to construct structures equalized to strategic (SES) in emergency, such as schools, churches, hotels and residential sites. These buildings have to play the role of fortified structures and haven for the local community in vulnerable areas, similarly to the historical castles in Europe or the historical forts in USA.
