HYPERION will perform extensive tests in four demo sites, in Greece (Rhodes), Spain (Granada), Norway (Tønsberg) and Italy (Venice). The historic areas will be modelled at building level through reduced-order models based on archetype structures of each area. A number of selected structures (CH value) will be modelled and monitored in detail. The demonstration shall prove the suitability of the HYPERION platform for multiple hazard assessment and optimized operational and strategic decisions for management and maintenance of the historic areas, considering as well other hazards relevant for other sections of the city.
