Abstract: Recent statistical reports highlight an accelerating phenomenon of radical urbanization, and the forecasts estimate that within the next ten years, about 70% of the world’s population will be located in urban areas, compared with 54% currently living there. This phenomenon will result in an increase in the constructed volume, with foreseeable adverse effects on the climate, the environment, and residents’ health. The resulting growth of the emissions and the use of energy resources, combined with changes in the soil condition and absorption characteristics, leads to a focus on issues related to the sustainable development of cities. The effects of anthropogenic activity influence the materials’ surface and air temperatures, contributing to the phenomenon of the increase of the average atmospheric temperatures near the earth’s surface, with the consequent generation of the phenomenon of the urban heat islands (UHIs). This paper aims to examine, in a neighborhood context, the effects of mitigation strategies implemented through the application of cool materials on urban surfaces. Through simulations carried out in a case study, with the support of software such as ENVI-met and tools for Grasshopper such as Ladybug, and with the observation of data related to the evolution of the surface temperatures, the air temperatures, and other microclimatic parameters, the outcomes obtained with the use of cool pavements were analyzed. Finally, the comparison between the two scenarios, the current and the projected, allowed the evaluation of the overall efficiency of the proposed interventions.
