This study aims to evaluate the relationship between the urban surfaces’ solar reflectance effect on the air temperature. Twelve parametric scenarios with different solar reflectance levels on the façades, pavements, and roofs were simulated through a validated ENVI-met model in Balneário Camboriú, Brazil. The results show that high solar reflectance surfaces provide an air temperature reduction. In denser areas, the solar reflectance of the facades exerts more significant temperature variation. The roofing and paving surfaces are more relevant in urban spaces with a higher sky view factor.
