As coberturas e fachadas mediterrânicas, vivas e produtivas promovem o bem estar e a qualidade de vida das populações e contribuem decisivamente para o aumento da resiliência das cidades. Por esta razão é essencial não apenas o conhecimento das soluções existentes que melhor se adaptam ao nosso clima, como ainda o desenvolvimento das competências técnicas essenciais para a boa implementação daquelas soluções. O enfoque deste Workshop está na demonstração da integração da dimensão verde nas cidades e das oportunidades de intervenção conducentes à melhoria do desempenho energético dos edifícios, à redução do “efeito ilha de calor”, à boa gestão das águas pluviais, à reciclagem de águas cinzentas, à melhoria da qualidade do ar, ao aumento da biodiversidade e à segurança alimentar das populações urbanas, sempre assentando nas melhores e mais adequadas tecnologias disponíveis.
