Outdoor climate has conducted man to build along the time a habitat climatic responsive.

The intent is to guarantee for new projects the socio-cultural image that people, coming from countryside to live in city outskirts, are accostumed. Also, to provide material improvements and functional adequation for a quality and healthiness. Natural ventilation is the main bioclimatic strategy during summer for thermal comfort, which influences the house characteristics. This is proven by calculation, and simulation with the CFX-ANSYS software. Thus, the analysis performed shows the real possibity to reconcile bioclimatism with the symbolic-cultural value represented by this vernacular architecture form. It is hopped that this study can be considered as a methodological contributition for new sustainable projects （materials, technics and services） of low-incoming houses in this Latin American region.展开更多
