Resumo: The aim of this study is to analyze experimentally the thermal behavior of an extensive green roof system compared to a control system. The experiment consisted of two test platforms built to reproduce an extensive green roof system, one of which perennial peanut was grown and the other one was maintained without vegetation. The temperatures of the upper and lower levels of the substrate and also external temperatures below the base of the platforms were monitored by means of thermocouples The climatic variables were recorded by the automatic weather station and the analysis of the thermal behavior was based on the approaches of dynamic climatology. The green roof showed better thermal performance compared to control coverage by having a larger thermal lag between the upper and lower surfaces, the lower temperature range on surfaces and lower maximum temperatures than the maximum air temperature. It was concluded that for a hot, dry day a dense vegetation cover influences the heat exchange process in the substrate layer by blocking the solar radiation, allowing the upper surface does not reach temperatures above the maximum daily air temperature and also that this temperature is registered with higher delay at the bottom surface.

O experimento foi composto por duas plataformas de teste reproduzindo um sistema de cobertura verde extensivo, sendo que uma plataforma recebeu o plantio de grama-amendoim e a outra foi mantida sem cobertura vegetal. Foram monitoradas as temperaturas dos níveis superior e inferior do substrato e as temperaturas externas, abaixo das plataformas, por meio de termopares. Os dados climáticos foram registrados por uma estação meteorológica automática e as análises do comportamento térmico foram realizadas a partir das abordagens da Climatologia Dinâmica. A cobertura verde apresentou melhor desempenho térmico em relação à cobertura controle por ter apresentado maior atraso térmico entre as superfícies superior e inferior, menor amplitude térmica nas superfícies e temperaturas máximas menores do que a temperatura máxima do ar. Concluiu-se que, para um dia quente e seco, a vegetação influencia os processos de troca de calor no perfil do substrato pelo bloqueio da radiação solar incidente, permitindo que a superfície superior não atinja temperaturas acima da temperatura máxima do ar diária e também  que esta temperatura se manifeste com maior atraso na superfície inferior.Universidade Estadual de Campinas2016-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa ExperimentalExperimental researchapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/864793210.20396/parc.v7i4.8647932PARC Pesquisa em Arquitetura e Construção; Vol. 7 No. 4 (2016): An overview of the theme of environmental comfort; 225-236PARC Pesquisa em Arquitetura e Construção; Vol. 7 Núm. 4 (2016): Um panorama sobre a temática do Conforto Ambiental; 225-236PARC Pesquisa em Arquitetura e Construção; v. 7 n. 4 (2016): Um panorama sobre a temática do Conforto Ambiental; 225-2361980-6809reponame:PARC (Campinas)instname:Universidade Estadual de Campinas (UNICAMP)instacron:UNICAMPporhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/8647932/15808Copyright (c) 2018 PARC Pesquisa em Arquitetura e Construçãoinfo:eu-repo/semantics/openAccessPerussi, RafaelVecchia, Francisco Arthur da Silva2017-05-22T10:57:23Zoai:ojs.periodicos.sbu.unicamp.br:article/8647932Revistahttp://periodicos.sbu.unicamp.br/ojs/index.php/parcPUBhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/oai||parc@fec.unicamp.br1980-68091980-6809opendoar:2022-11-08T14:24:37.510189PARC (Campinas) - Universidade Estadual de Campinas (UNICAMP)false
