Ventilation in Self-Built Houses - A Study Through Wind Tunnel Measurements in Campinas, Brazil

Natural ventilation of buildings is a design strategy for the passive cooling of buildings that can be considerably efficient if properly undertaken. In Brazil, as in many other developing countries, spontaneous (self build) housing is often of poor quality. Also, each of these dwellings has a negative impact on the neighbouring ones and on the impact on the urban environment. In the city of Campinas, Brazil, with its hot-humid climate, adequate ventilation is essential for thermal comfort.
