Mitigation strategies in densely urbanized contexts: the case study of a historical district in Naples

Abstract The design of our cities, their planning, and management must be increasingly oriented towards sustainability, identifying solutions that can systemically address problems on a city scale, namely urban heat islands, rainwater runoff, storms, acoustic issues. This study begins by evaluating the impact green area pedestrian comfort in historical center Naples, employing an experimental numerical approach. Temperature, relative humidity, CO 2 concentration were measured at three significant points quarter “Chiaia” district (Naples): a) square “Piazza del Martiri” sun, b) same shade, c) shade vegetation, under effect transpiration deep trees. Then, these measures are used for calibration model developed environmental analysis software. approach has been to predict possible mitigation scenarios, increasing vegetation varying density canopy, using non-white cool materials surfaces facades roofs surrounding buildings, adding fountains. These strategies have positive temperatures outdoor comfort, densely urbanized contexts. findings finally identify best solutions, improve reduce heat, without affecting value district.
