Resumo

Para evitar os perigos de superdimensionamento, custos iniciais e de manutenção elevados, e carregamento desnecessário sobre o telhado de suporte, o objetivo principal deste estudo foi determinar a diferença significativa na capacidade de redução da temperatura interna entre diversos modelos de telhados verdes de diferentes espessuras, dentro da categoria de telhados verdes extensivos. Utilizando uma camada de substrato contextualizada com uma diferença de profundidade de 25mm entre as alternativas de telhados verdes, observou-se o grau de isolamento térmico para o interior em seis modelos de telhados verdes extensivos com espessuras de 50mm, 75mm, 100mm, 125mm e 150mm. O objetivo foi elucidar o nível de diferenças significativas na eficiência térmica entre os modelos. O software de simulação EnergyPlus 8.3.0 foi utilizado para conduzir uma análise de desempenho térmico nos modelos amostrados. Os perfis de temperatura de todos os casos foram coletados e submetidos a uma análise estatística utilizando o SPSS V 21.0, com realização de um teste ANOVA seguido de um teste Post hoc para determinar onde residem as diferenças entre os grupos de telhados verdes. Os resultados revelaram que não existe uma diferença substancial no desempenho térmico entre alternativas onde a diferença de profundidade é em torno de 25mm. Foi identificado que o limiar para qualquer mudança significativa no isolamento térmico é marcado por uma diferença de 50mm entre as alternativas. Esta pesquisa foi conduzida para facilitar o processo inicial de seleção, projeto, detalhamento e especificação de telhados verdes para arquitetos, engenheiros e outros stakeholders.
