Evaluation of Microclimate Benefits Due to Cool Pavements and Green Infrastructures on Urban Heat Islands

Ongoing climate change is manifesting in the expansion of urban heat island (UHI) effect. This paper evaluates microclimate benefits cool pavements and green infrastructures a historical square Rome, Italy. The ENVI-Met software enabled us to conduct microclimatic analysis examined July 2021, through comparison thermal performances current asphalt sampietrini pavement (AS) with three alternatives. proposed options are existing layout include: light concrete slabs furniture consisting 5 m high trees (LC+G1), perimeter hedge (LC+G2), 15 (LC+G3). effects road as passive countermeasures UHI effect investigated terms air temperature (AT), mean radiant (MRT), predicted vote (PMV). results show that worst option, while integrated vegetation greatly beneficial human comfort. Compared layout, LC+G3 best scenario, because it implies an AT reduction higher than 3 °C, MRT equal 50%, maximum PMV value 2.2.
