Il controllo ambientale negli interventi di riqualificazione degli spazi urbani del Centro Storico di Napoli: monitoraggio, simulazione e verifica con l’utilizzo di strumenti IT

The current scenario of technological experimentation, puts the project of urban space at the center of a reflection on the environmental design, following the guidelines defined within the climate & energy package of Horizon 2020. Parameters and strategies regeneration of the built environment, providing highest levels of urban quality. Strategies of adaptation and mitigation through technical solutions and design actions that can make the urban space resilient to the worsening of weather caused by global warming. Urban spaces adapted to user’s needs, improving the outdoor comfort to regain places for living together. The experience of research done with the "Project for the redevelopment for the Great Project UNESCO for the Historic Centre of Naples” provided the ideal field of experimentation for the definition of a workflow to determining design and technical solutions for urban redevelopment, verifying the compliance to the objectives of adaptation to climate change with IT tools. Software and tools, allows to control and tests micro-climatic and environmental conditions in the built environment. To get closer simulations to real conditions, it has been tried to perform a sort of instrument calibration of IT tools, with the insertion of the data collected as a result of instrumental monitoring (air temperature, surface temperature, relative humidity , ventilation, etc.), to obtain a real correspondence between the real built environment and the simulated one. It was also defined a database containing the properties and characteristics of materials and technology packages (thermal conductance, albedo, surface emissivity, etc.) of the horizontal surfaces of the open spaces of the historic center of Naples. Using data on increasing temperatures of scenarios of Climate Change (IPCC), the year allowed us to define ad hoc design solutions for the historic center of Naples, helped define ad-hoc design solutions to improve urban comfort in the historic center of Naples in present and future. The obtained results of values for specific parameters of thermal comfort, such as the MRT (Mean Radiant Temperature) and the PMV (Predicted Mean Vote) allowed to verify the real benefit of chosen design solutions for the reduction of perceived temperature, fostering the fruition of urban spaces to provide opportunities to socialize and get together.
