Contribuições da vegetação nos microclimas urbanos de uma Superquadra do Plano Piloto de Brasília

Abstract

This project intends to identify the contribution of the vegetation on urban microclimates. The "Superquadra 108 Sul" of Brasilia's "Plano Pilo-to" was taken to illustrate this project's main goal due to its pleasant environment, which clearly represents the original concept of "superquadra" created by Lucia Costa. Three significant areas of vegetation distribution were analyzed within the surrounding vicinity, each with increasingly green area percentages, considering horizontal surfaces, and vegetation in order to analyze its effects on superficial temperature of materials_ The analysis was completed on two significant periods of Brasilia's climate, the dry season (May through September) and the rainy season (October through March), by means of field mea-surements and computational simulation on the ENVI-met tridimensional model which simulates urban microclimates. The research showed that the vegetation had major impact on urban micro-climates regarding the attenuation of superficial temperature diminishing it, in some materials, from 52.84° C to 28.74° C. It could also be con-cluded that lawn alone, does not result in signifi-cant improvement on urban environment com-fort during the dry season.
