Energy efficiency, sustainability of interventions and efficient management of the conservation process are three increasingly important features of the restoration and regeneration of urban historic fabrics. Several studies identify in the Heritage-BIM the most suitable instrument for the integration and management of knowledge produced during the conservation process, with ongoing experiments that, from the field of representation and geometric survey, have gone in the direction of a multidisciplinary approach. Numerical simulations are one of the most powerful tools for improving energy efficiency of the built heritage, not only for the understanding of complex phenomena and the analysis of the energy and environmental consequences of conservation interventions (also in terms of deterioration), but also because they allow innovative applications in the field of non-destructive analysis and in the reconstruction of the original passive behaviour of historic structures. An HBIM model already contains much of the information required for numerical analysis of historical structures, and interoperability can save time by reducing errors in manual steps but at the moment the process of integration between the two software environments is still complex and in an embryonic phase that requires a multidisciplinary approach and the involvement of numerous experts from different scientific fields. The article describes the methodology of integration between multidisciplinary analyses, HBIM modelling and simulation analysis adopted within the METRICS research project, where it was possible to test the limits and potentials of the currently available approaches, exploiting the digital medium of computational design to bridge the gap between BIM and simulation environments.

This paper presents a case study of the La Salata geoarchaeological site (National Park of Gargano, southern Italy), where the cultural value of the necropolis is in addition to that geological, linked to the presence of one of the most beautiful Mediterranean exhibitions of Eocene bioclastic limestone facies at Nummulites and the presence of karst landforms. The site is an excellent example of integration of environmental and cultural values that favor an increase of cultural tourism for the benefit of communities and local businesses. However, the site should be subject to protection through initiatives to consolidate the fronts of slopes subject to rockfalls and often affected by the cavity collapses. In this sense, the most attention has been offered by the private rather than public sectors, including in these last the national, regional and local Authorities.

Testing and performance evaluation of piezoelectric devices for energy harvesting from vibrations are tasks of great relevance for the development of these devices. Thus, the definition of a test methodology that satisfies these goals is a preliminary requirement of this research activity. Because of the electro-mechanical nature of these devices, the preparation of the experimental set-up involves a multidisciplinary approach which includes mechanical and electrical measurements. Therefore, in this technical report, the development of an experimental methodology for testing these systems is proposed with reference to a specific set-up so as to clarify some aspects, including the choice of suitable instrumentation for the purpose.
