“…Moreover, the results achieved are in line with the findings of similar studies performed with relation to different urban contexts and building types. The CP emerged as the most effective retrofitting strategy at the urban level, in mitigating the external air temperature, as proved also by other studies in this field [50][51][52][53]. Its efficiency is undoubtedly connected also to the wider area covered but its adoption can also result in some side effects.…”

The European goals to reduce CO2 emissions by up to 40% by 2030 and reach carbon neutrality by2050 cannot ignore the building sector, that accounts for 27% of global greenhouse gas emissions. In the context of the sustainable development goals, it is a key point to consider the reduction of the heat island effect in the urban environment. Considering this background and the proven absence of the clear promotion of urban mitigation measures, the research aims at investigating the influence on several micro-climate parameters of different retrofitting strategies at the building level (green façades) and the cooling strategies at the urban scale (e.g., cool pavements, trees). As a case study, the application of these measures in an industrial district located in Italy is evaluated. ENVI-met software was adopted to perform the outdoor environmental simulations, in order to assess the effectiveness of the mitigation strategies proposed, considering both the whole district and a portion, focusing on urban canyons. Cool pavements proved to be the most promising strategy to both reduce the air temperature and increase the relative humidity. Slighter effects on environmental conditions can be achieved by planting trees and installing green walls that, by contrast, significantly affect the mean radiant temperature and buildings’ surface temperatures, respectively.
