Passive cooling through natural ventilation has a great potential for single-family homes and temperate continents such as the city of Mendoza, located in the central west of the Argentine Republic. This strategy seeks to end the risks of overheating and reduces the energy consumption of mechanical conditioning equipment. This study aims to evaluate the influence on energy consumption, in two ventilation scenarios (day and night) for two constructive resolutions (light and mass). For this, a computational model of a single-family house, modeled and adjusted in the Energy Plus v8.6 program was used. For the ventilation model, “Airflow Network” (AIRNET algorithm) validated by Gu (2007) y Crawley et al. (2001) was used. The results indicate that, in the construction as well as in life, with night ventilation the energy consumptions are lower in 50% than they ventilate during the day. The natural ventilation in bioclimatic buildings is an indispensable strategy for the cooling of the same. In this situation lies the importance of having a simulation tool to test different scenarios of use and control of the same.
