In this article the geothermal potential is quantitatively explored to be used as a passive system of building cooling in an urban arid environment, taking as a study case the San Juan Metropolitan Area. The climate database for the summer season is used as input. It was obtained at the University Malvinas Islands (CUIM) of the National University of San Juan, place where the Institute of Studies in Environmental Architecture "Arq. Alberto Papparelli"(INEAA), records temperature of the soil at different depths, and environmental meteorological parameters. The results are related with the identification of gradients and optimal depths to be used as geothermal resources for passive cooling system in order to provide hygrothermal comfort in arid urban zones during summer. In average a maximum of 8.7 degrees C difference between the temperature of the air and the ground to a 3m depth. The length of the underground tubes required results from 64m to a velocity of 3 m/sec, which falls down to 27m for an air speed of 2m/s.
