The object of this PhD thesis is the development of methodologies for the modelling and evaluation of technical solutions, guidelines for the design and implementation of new industrial products for the building envelope aimed at volcanic risk mitigation and energy saving. The areas studied are the urban settlements in the Neapolitan volcanoes Vesuvius and Campi Flegrei (Campania Region, Italy). The phenomena analysed within the Neapolitan explosive eruptions because they are considered most destructive are pyroclastic flows and ashfall. In the case of pyroclastic flows, a gas-solid mixture that can flow downstream and reach considerable distances from the point of emission, with speeds that can easily exceed 100km/h ( 30m/s), the damage caused to buildings depends on several factors, including the duration of the phenomenon, the temperature of the flow and the impact pressure. At the same time, ash falls, which are formed by the accretion of clasts falling by gravity from an eruptive column, affect (albeit with different levels of intensity) a large area, the definition of which is closely linked to the direction and intensity of the wind and the type of eruption. Thus, the Emergency Plans, developed by the Civil Protection for both volcanoes, identify the "red zone', as an area potentially affected by both pyroclastic flows and the risk of roofs collapse in a short time due to ashfall. For this zone, the only solution is a preventive evacuation of the population. The research project tries to identify potentially resilient sectors within the red zone, where the structures, whose vulnerable elements such as windows and roofs have been strengthened, can resist the actions foreseen.
