DECEMBER 2020CIOAPPLICATIONSEUROPE.COM 19ransforming Milan into a smart city is a strategic objective and political priority of the Municipality, which has taken up a variety of projects and experiments to tackle the pressing societal challenges, with the aim to transform the main suburbs of the city in smart areas. The most significant is certainly the five-year EU project "Sharing Cities", a European project involving Milan, London, and Lisbon as lighthouse cities, aimed at testing a smart district pilot. In Milan, the pilot area is Porta Romana/Corvetto/Vettabbia, where technical solutions are tested through the involvement of key stakeholders, to trigger innovation processes instrumental to become a more resilient, socially and environmentally sustainable city.Based on a holistic "people, place, and platform" approach, it implemented a variety of innovative tools and measures in relation to the three dimensions of people (user-centric smart city services co-designed with citizens), place (infrastructure solutions for: low-energy districts, e-mobility, retrofitting of buildings, installation of sustainable energy management systems and smart lampposts) and platform (urban sharing platform based on open data). Such approach allowed to test the "human-centered smart cities" concept, recognising the pivotal role of citizens rather than technology, crucial to enable the behavioral change, necessary to transform cities and maximize the policy effectiveness. The project carried out six main actions in the "Sharing Cities" area regarding Deep Building Retrofit, Shared e-Mobility (with five sub domains: charging points, e-car sharing, e-bike sharing, e-logistics, and smart parking), Smart Lampposts, Sustainable Energy Management Service (SEMS), Urban Sharing Platform (USP) and Digital Social Market (DSM), with the aim of replicating and scaling up to the rest of the city.Deep Building Retrofit 328 flats, 24,000 sqm of private and 4,500 sqm of public residential buildings have been deep retrofitted allowing an average 60 percent reduction in energy consumption and increasing comfort inside dwellings, by means of the stabilization of internal temperature at 24-25 degrees, and humidity level at 30-70 percent. Deep retrofit interventions consisted in renewing the buildings by integrating them with low carbon energy sources (solar PV, water source heat pump) and energy management systems which serve for monitoring and managing the energy consumption. Technical planning based on an inclusive approach envisaging owners' engagement through co-design processes. A series of meetings and workshops were organised with the aim of collecting needs and providing information to the buildings' owners about the project content and the energy efficiency interventions. Such co-design process proved crucial to the implementation of the deep retrofit interventions as it created consensus and CREATING A RESILIENT AND SUSTAINABLE SMART CITYPIERO PELIZZARO, CHIEF RESILIENCE OFFICER - DIRETTORE DELLA DIREZIONE DI PROGETTO "CITTÀ RESILIENTI", COMUNE DI MILANOTFigure 1 Sharing Cities three domains (people-place-platform)Figure 2 Private residential building pre and post retrofitting funded by Sharing Citiescxoinsights
