Clima urbano, Adensamento urbano, Ventilação natural, Sombreamento, Conforto térmico externoResumo
O adensamento urbano oriundo do processo de verticalização provoca alterações no comportamento térmico que, a depender da localidade, podem beneficiar ou prejudicar a qualidade microclimática urbana local. Este artigo parte de uma pesquisa de Iniciação Científica e objetivou realizar revisão narrativa da literatura recente acerca da influência da verticalização no microclima urbano em cidades tropicais. A revisão foi realizada a partir da busca nas plataformas Scopus e Web of Science, da qual foram selecionados e analisados 37 artigos em língua inglesa. Os artigos analisados mostraram que o Fator de Céu Visível (FCV) e a relação H/W dos cânions urbanos estão fortemente relacionados à formação das Ilhas de Calor e ao conforto térmico no ambiente urbano. Em cidades tropicais, onde o ganho térmico deve ser evitado, a verticalização traz benefícios quanto ao aumento da velocidade do ar no nível do pedestre e o aumento das áreas sombreadas, podendo, ainda, ser aliada ao incremento de vegetação, áreas permeáveis e corpos d’água auxiliando na regulação do microclima em cidades tropicais. Espera-se que a compilação obtida nesta revisão possa fomentar novas pesquisas e discussões sobre a temática de modo a subsidiar políticas públicas, com vistas à melhoria dos aspectos bioclimáticos no ambiente urbano.
