ELISIR project: eco-seismic building regeneration 4.0

Gexcel will provide its own technologies in 3D mapping, fast 3D digitalization, and BIM model update within the ELISIR project. These technologies are essential to drastically reduce costs and times of surveying activities and to assess in real-time the as-built conditions of a building.

ELISIR stands for Energy, Life Styled & Seismic Innovation for Regenerated Buildings and it aims at exploiting the potential of digitization in order to create a very personalized product-service to be offered on the market of the existing building heritage focused on seismic improvement and energy efficiency in a "smart living" way, developing a real "Built in Italy". The research project has been launched last November with a research call funded by the Lombardy Region and will end in May 2019.

Gexcel participates in the project, along with other important partners, using the HERON technology for the rapid survey of buildings, for the as-built data acquisition in the form of a point cloud, and will further develop the product adding the possibility of collecting camera data. Schneider will contribute by developing appropriate sensors for energy analysis, a platform for collecting, storing and processing data and validating them. Valsir will undertake the development of hydraulic connections leveraged by sensors, to monitor all the water consumption of the various users. H&D will craft appropriate financial products to provide "the business model and a brand capable of spreading and introducing innovation in the supply chain" with possible "consequences on foreign markets that will be investigated together with the partners involved". Delta Phoenix will fine-tune the energy seismic plaster. The development of smart windows will be taken care by Italserramenti, which will experiment products with a high degree of automation and intelligence, able to adapt to users' needs and independently manage environmental comfort.

The concept of the project was born at the DICATAM headquarters in the University of Brescia, on the initiative of Angelo Ciribini, one of the leading experts in Building Information Modeling (BIM) and digitization in construction. The second university involved is the Milan Polytechnic, with the Abc department - Architecture, Engineering and the built environment, and in particular with the operating units "Building envelope engineering group" and "Sustainable building process management group". Find more...

SUCCESS CASE — CONSERVATION, RECOVERY AND RESTORATION OF HISTORICAL BUILDINGS

The ancient complex "Convent and Prison of S. Domenico buildings" San Gimignano, Siena (Italy)

PDF versione italiana


PROJECT DESCRIPTION

KEYWORDS: Classification Mapping | JRC 3D Reconstructor | 3D Laser Scanner | Heritage | Architectural

Assignment carried out in 2016 and 2017 for the underground part, commissioned by the Public Authority of San Gimignano (Siena) to the "RTP Borromini" group, a multidisciplinary professional team composed of specialists in architecture, engineering, restoration, and archaeology. The STUDIO ASSOCIATO PERIGEO was involved in the topographic and laser scanners survey. The complicated geometries detected with the 3D laser scanner, together with the accurate topographic survey, were then used for all the subsequent phases of detail analysis and output of a unique georeferenced system. Thanks to the data processing software JRC 3D Reconstructor, it was possible to collect and share 3D outputs from laser scanner scans and an in-depth evaluation of underground constructions of historical and anthropological interest.
