ANÁLISE DA VENTILAÇÃO E DA TEMPERATURA SUPERFICIAL DA SUPERQUADRA 500 DO SUDOESTE - BRASÍLIA DF

Abstract

In the southwest neighborhood of Brasilia's Plano Piloto, in a region previously covered by native vegetation and with no occupation forecast in the city's initial planning, construction work began on a new superquadra at the end of 2019, turning what was previously permeable soil into an impermeable surface. The research analyzed the impact that the implementation of this new development will have on the ventilation and temperature of the neighborhood's surroundings. Remote sensing was used - freeware Qgis v. 2.18, to identify the surface temperature of the region before construction of the project, and computer simulation - software Envi-met v.4.4.3, to identify the surface temperature, wind speed and direction after construction of the project. The simulated scenario reveals the significant increase of more than 10°C in the surface temperature of the superquad due to the implantation of the buildings in several directions, the suppression of native vegetation, the roughness of the surfaces and the increase of albedo, which will significantly alter the direction and speed of urban ventilation. The parameters analyzed indicate the new superquadra as a potential urban heat island (uhi) area for the existing neighborhood, which already presents lower sustainability standards when compared to those designed by Lucio Costa1.
