The built landscape modifies the micro-climatic parameters of a site. One of the major impacts is the increase of the air temperature, which gives rise to the phenomenon of urban heat island (UHI). The UHI increases the demand for electricity and decreases the livability of the interior and exterior spaces. This paper aims to identify urban forms that help to mitigate the effect of the UHI in Mendoza; analyzing and comparing the thermal behavior of 10 representative urban canyons during the summer. The results show that the open-forested group of cases keeps cooler compared to the compact-without forestation, ΔT°mean=2.5°C. But to propose the open-forested scheme for urban growth in arid cities, it is necessary to perform a discussion that consider other aspects of urban planning, including the energetic and environmentally standpoint, to ensure sustainable urban development.
