TELHADO VERDE: ALTERNATIVA SUSTENTÁVEL PARA A DRENAGEM DO ESCOAMENTO SUPERFICIAL

Sustainable urban drainage is a technique that aims to maintain natural landscapes and reduce impermeable areas, such as when the green roof is implanted. Green roof is an alternative to consider for large urban centers, consisting of the vegetation cover of a building, either on slab or conventional roof. In this work we investigated aspects and factors that may affect the quality of the green roof surface runoff storage, as well as its environmental and economic contribution. Thus, external characteristics such as weather and seasons, and internal characteristics related to the physical structure of the roof were analyzed. Public policies that encourage the implementation of this type of coverage were also investigated. The green roof contributes to urban drainage management, assisting in the capture of rainwater and can improve air and water quality and reduce runoff overload.
