Abstract: The impact of reflective and permeable pavements on the urban microclimate is investigated in this study by means of a fully-integrated urban microclimate model, which couples the transport of heat and moisture in the air and the building materials as well as the solar and thermal radiative exchange between urban surfaces and the sky. The proposed approach yields detailed analysis of the impact of di↵erent types of pavement materials on the absorption and storage of heat and moisture in urban environments. The case study of an isolated street canyon shows limited evaporative cooling potential and decreased thermal comfort conditions for conventional impervious pavements and dark-colored surfaces compared to porous pavements and high reflective materials.
