Potential of Natural Ventilation in a Tropical Climate

Sustainable architecture design for tropical climates requires the use of natural ventilation besideseveral strategies, as appropriated materials, site location, faade orientation, solar shading, etc. Theindoor thermal comfort and thermal performance of the building depends on the bioclimatic zonewhere is located. The new Brazilian Norm ABNT NBR 15220-3 has established bioclimatic zones and guidelines for low-income houses. Due to the lack or scarcity of meteorology wind data, certainregions as Amazon and Northeast coast were inserted in a same zone.
