The effectiveness of urban climatology applied to the practice of planning depends on the self-understanding of the city. Internationally, various strategies to mitigate the effect of urban heat island and improve thermal habitability of outdoor spaces have been proposed and studied. This work evaluated the effect of vegetation and building density in two different climates, tropical of altitude-Campinas Brazil, and warm dry in Mendoza, Argentina to determine their potential to reduce urban temperatures. Eight scenarios were simulated by the numerical model ENVI-Met micro climate with this purpose. The results show that the greatest beneficial impact of vegetating occurs in low density scenarios during the maximum temperatures. Because of the particular characteristics of tropical altitud climate, the city more susceptible to changes in the vegetation is Campinas, which registers maximum differences of 4 ºC in its air temperature, while in Mendoza the thermal differences reach 1 ºC. Therefore we concluded that densifying increases the urban temperatures during the cooling period in both climates and this contributes to the formation of the ICU.
