The study was developed with the aid of experimental simulations in a wind tunnel, taking into account the urban morphology and its relations to open spaces. A diagnosis was produced through the exam of the wind effects in relation to the volume of built and non-built spaces. The effects were classified as positive or negative, in relation to the tropical climate. At first, both blocks studied, one in Ipanema and one in Copacabana, were selected according to common characteristics, which establish a relation between the two regions, such as the distance to the beach and the presence of a public square. The results confirmed our expectations showing Ipanema as a more ventilated area.展开更多
