Infraestruturas verdes no contexto urbano: a aplicabilidade do teto verde e jardim de chuva na cidade de São Luís-MA

Abstract

The use of green infrastructure in urban areas it has been a way to mitigate the environmental problems caused by urbanization in cities. These sustainable technologies have been applied for some time in several European countries and in some Brazilian cities, as way to help solve urban problems like heat island, absence of original vegetation, decrease in permeability rate that contributes to the occurrence of floods and other problems observed in density urbanized areas without planning. The city of São Luís naturally has a high thermal sensation throughout the year, however, with increased investment in real estate and the lack of investor concern to maintain and improve the environmental quality of the inhabitants, the sensation of heat has increased and the city has been experiencing more unpleasant microclimates, due the high concentration of buildings inversely proportional to the presence of green areas in the urban space of the city. The proposal to use green infrastructures in São Luís, specifically the green roof and rain garden, aims to soften the set of environmental comfort problems, thermal and drainage systems observed in the city. Through of bibliographic research and the understanding of the operation and applicability of these structures, it was possible to find the best way to implant these structures in the study city, through the necessary adaptation required by the structural, environmental and geographical conditions presented.
