Abstract

In some of the coastal capitals of the Brazilian northeast states, the building verticalization of seaside areas represents a potential barrier to the air flow through the built environment, towards the inner city areas. In São Luís, capital of the state of Maranhão (MA), the verticalization process has begun along Litorânea Avenue, which is a 5,3km long street located in Calhaus Beach district. In this context, the objective of this research work is to investigate the relationship between this imminent verticalization and the natural ventilation. In order to fulfill such objective, there were created five different fictional scenarios of verticalization among the sites placed in Litorânea Avenue, which were gathered according to the height, distances between buildings and buildings typology. These scenarios were simulated in Ansys CFX Software and compared with the areas current situation. Along six blocks of the avenue, 24 points were distributed and monitored, observing the influence of each proposed scenario in the wind velocity and direction patterns, also considering the pressure in the pedestrian level. As a conclusion to this study, the pointed scenarios of verticalization have proved to result in significant influence in the wind pattern, distinguished from each other. Contributing to the urban planning of the city of São Luís, this research anticipates the impact of new buildings in the air flow of already occupied seaside areas. (AU)
