Re-thinking Re-construction. New design strategies for the reconstruction after natural disasters. A local research experience for a global topic,

The paper presents the ongoing results of a design research carried out at the School of Architecture and Design ”Eduardo Vittoria” of Ascoli Piceno (SAAD) of the University of Camerino. The specific objective of the research is to develop an innovative and replicable design methodology, and to experiment new design strategies devoted to the sustainable, compatible and innovative re-construction after natural disasters in rural areas and lowdensity urban systems. The research is based on a “local-to-global” approach: it refers to Italy as a case study but it aims to achieve general results applicable in different geographical contexts. The specific case study relates to the earthquake that in 2016/2017 affected a significant area of Central Italy and that strongly hit a large part of the so called “Italian village system”, i.e. a peculiar environmental and productive urban system that is still now in real emergency. As in most of the international reconstruction experiences, this reconstruction will certainly require a long process which, still today, is full of unknowns. The massive damage caused by this disastrous event, the constraints imposed by regulations and the need for an adaptation of the building stock to the current housing standards, exclude the possibility of applying design strategies focused on a “where it was/as it was” model. This awareness, which increases the uncertainty about the future of the ”earthquake” communities, requires an innovative approach in relation to apparently incompatible aspects: the preservation of the identity of lost places and the upgrade of building performance often explicitly required by the population and however connected to a new housing demand. In relation to worldwide territories with a high level of disaster risk, this scenario can nowadays be considered a global issue which concerns both cultural and technical aspects. The design methodology pursued is based on a scientific approach to re-construction that focuses on a “systemic” and “design to build” approach that concerns also productive and technological aspects in relation to purposes of low-cost performance, constructive simplicity, cost-effectiveness of the interventions. This approach aims also at the introduction of lightweight building system in contexts of traditional and massive construction, according to an idea of a construction site as an “assembly point” of prefabricated parts, light and modular, with a controlled life-cycle.
