Theeffectiveness of urban climatology applied to the practice of planning dependson the self-understanding of the city. Internationally, various strategies tomitigate the effect of urban heat island and improve thermal habitability ofoutdoor spaces have been proposed and studied. This work evaluated the effectof vegetation and building density in two different climates, tropical ofaltitude-Campinas Brazil, and warm dry in Mendoza, Argentina to determine theirpotential to reduce urban temperatures. Eight scenarios were simulated by thenumerical model ENVI-Met micro climate with this purpose. The results show thatthe greatest beneficial impact of vegetating occurs in low density scenariosduring the maximum temperatures.Becauseof the particular characteristics of tropical altitud climate, the city moresusceptible to changes in the vegetation is Campinas, which registers maximumdifferences of 4 ºC in its air temperature, while in Mendoza the thermaldifferences reach 1 ºC. Therefore we concluded that densifying increases theurban temperatures during the cooling period in both climates and thiscontributes to the formation of the ICU.
