description |
Flooding problems in urban streets, resulting from the combination of occurrence of heavy rains and excess sealing of urban spaces, have caused severe losses to Brazilian cities. The green roof with your rainwater retention capacity is an interesting alternative to reduce the discharges on urban drainage systems. In this article, we will analyze the rainwater retention potential, from an extensive modular green roof, proposed with precast cementitious with lightweight aggregates of Ethylene Vinyl Acetate (EVA), originated from footwear industry waste. For this, were compared results from monitoring the volumes of rainfall over the proposed green roof and conventional roofing, all installed on prototypes. Additionally, a simulation was performed to estimate the rainwater retention capacity in a hypothetical scenario, in which a small portion of the city's buildings covers were installed green roof proposed. The additional contribution to rainwater retention due to the presence of lightweight aggregates on the modules was confirmed. It has also been demonstrated that the rainwater retention capacity by green roof proposed may vary between 73.3% and 90.5%, as the soil is wet or dry, respectively. The retention volumes estimated in the city's simulation can be up to 4 million liters/day in dry conditions on the green roof. Indicating that this type of coverage is encouraged in buildings; there is the potential to mitigate flooding problems on city roads. |

Os problemas de inundação nas vias urbanas, decorrentes da combinação da ocorrência de fortes chuvas e excesso de impermeabilização dos espaços urbanos, têm causado sérios prejuízos às cidades brasileiras. O telhado verde com sua capacidade de retenção da água de chuva é uma interessante alternativa para reduzir as descargas nos sistemas de drenagem urbana. No presente artigo, procura-se analisar o potencial de retenção dessas águas, a partir de um telhado verde, proposto com pré-moldados cimentícios com agregados leves de Etileno Vinila de Acetato (EVA), originados de resíduos da indústria de calçados. Para isso, foram comparados resultados a partir de monitoramentos dos volumes de chuvas sobre o telhado verde proposto e coberturas convencionais, todos instalados em protótipos. Adicionalmente, foi feita simulação para estimar a capacidade de retenção das águas de chuvas num cenário hipotético, no qual uma pequena parcela das coberturas das edificações da cidade fosse instalada o telhado verde proposto. A contribuição adicional na retenção das águas de chuvas devido à presença dos agregados leves nos módulos foi confirmada. Também foi demonstrada que a capacidade de retenção da água de chuva pelo telhado verde proposto pode variar entre 73,3% e 90,5%, conforme o solo esteja seco ou úmido, respectivamente. Os volumes de retenção estimados na simulação para a cidade podem ser de até 4 milhões de litros/dia na condição de solo seco no telhado verde, o que indica que, caso este tipo de cobertura seja incentivado nas edificações, há potencial para mitigar os problemas de enchentes nas vias da cidade.
