Conserving the beauty and the identity value of small historical centers of the zones in condition of marginality, together with guaranteeing their good-quality livelihood is one of the main challenges of urban planning nowadays. New instruments that incorporate computing and communication technology can contribute to address the inefficiencies of predictive top-down traditional urban planning tools. The Protocol “Historical Small Smart City” is an innovative tool based on a bonus certification system to stimulate the small municipalities to submit regional funding integrated projects. It prescribes the “modulation of the protection” to achieve the goal of conserving the built minor heritage and also allowing certain degrees of energy retrofit.

This tool can calculate different scenarios simulating possible developments linked to different decisions. GIS Data Analysis is the core basis of this system, set through a Geo Big Data and Local Data portal that allows calculating different indicators to orient political decision-making.
