The Urban Sectorization of Lúcio Costa's Modernism and the Emergency of Heat Islands in the Capital of Brazil

The aim of the article is to present a new approach for understanding the urban design effects on heat island phenomena, studying the case of the city of Brasilia. Satellite images and comparing simulations from two distinct areas of the capital are used as basis of the hypothesis that the urban planning of the city favoured its emergency of heat islands. The satellite image is adopted to provide a greater scale of the current scenario, gathering different sectors of the modernist city. At the same time, the simulations offer a closer view of the working and habiting sectors, demonstrating practically in which way the space configuration and materiality of those corroborate to change the urban climate.
