A GIS-BIM Approach for the Evaluation of Retrofit Actions in Urban Planning. A Methodological Proposal

Abstract

In the last years, the increase in urbanization has caused the deterioration of urban environments. Consequently, a series of evaluation frameworks has been developed to monitor the sustainability of urban transformations. Considering the complexity of the urban and territorial scale, professionals need a tool capable of satisfying the planning, design and management needs of urban space. The large amount of data and the possibilities of managing the multiple information contained in a BIM model can, indeed, be integrated usefully and declined at higher scales than the single building one, since they can be extended from the sphere of pure architectural design to the spatial field. In such a wide context, the GIS-BIM approach can represent a real shift of paradigm aimed at managing the complexity of urban processes more effectively. In this paper a methodology focused on the integration of GIS and BIM to design sustainable spatial scenarios of urban transformations will be presented and applied to a case study in south of Italy.
