Thermal impact of a redeveloped area on localized urban microclimate: A case study in Rome

The new redeveloped configuration of the area induces an increase in average air temperature up to 3.5 °C in the central part of the day and a worsening of the maximum UTCI index up to 2.7 °C. This is caused by the increase of the number of obstacle to the natural ventilation, the replacement of soil and spontaneous vegetation with low albedo materials. The application of cool materials and vegetation determines a temperature decrease up to 2 °C, while the maximum UTCI reduction is moderate, about 1 °C.
