Telhado verde: alternativa sustentável na arquitetura

Abstract

Brazil is definitely a urban country. Over 2/3 of its total population live in an urban environment (IBGE, 2001). associating the urban growing with the soil usage, we can see the great disorder and legislative insubordination in which this process is inserted: the famous ¨Brazilian way¨ that shows its dominium within soil usage. The negligent usage of the soil has been limiting the green areas natural functions and the soil itself, not letting them absorb solar radiation, take the pluvial water to the phreatic zone nor bring natural thermal comfort, which leads to negative environmental impacts. Fearing a future collapse, several ecological actions are being adopted by the current society. Within the Architecture and Urbanism field studies have revealed the preservation importance, and mostly, ways to recover the natural environment characteristics of large urban areas without forgetting the incontrollable urbanization process. The technique known as Green Rooftop, existent for a long time, has become a great tool on environment recovery of the contemporary world. European and Asian countries are highlighted due to the fact they have already linked to their legislation the implementation of Green Rooftops. It´s an easy and fast way besides of being applicable anywhere for the flexibility of its elements allows it to adapt itself to the local aspects, to revert the environmental impacts and its social repercussion where not only the user becomes privileged by the means of returning to a life within the green, but also for the rescue of sustainability´s natural conditions for all citizens, inhabitants of a urb.
