Potential of Natural Ventilation in Mexico According to Its Hours of Hygrothermal Comfort

Abstract

This work shows, through monthly maps, the potential of natural ventilation in order to cool down buildings in the different climatic regions of Mexico. By using the method of energy evaluation of buildings in Brazil applied to Mexico, a monthly electric-power saving factor is calculated to use natural ventilation for the forty-three biggest cities of the country according to their hours of hygrothermal comfort. Then, with the Geographical Information System Map Maker, monthly maps were created from the potentials of saving for the Mexican territory. Then, energetic, economic and environmental benefits were estimated for year 2006, in comparison to the realistic energy consumption in the same year.
