Resumo: | The continuous living wall is a type of vertical garden built with different layers, which allows the cultivation of a wide variety of species and protects the façade from direct sunlight. From this, this experimental study aimed to identify and quantify the influence of a continuous living wall on the variations of the internal and external surface temperatures (Ist and Est) of an East façade, in the winter period, in the Cfa climate. The garden had the differential of being built with Tetrapak® recycled boards to differentiate it from the other technologies already studied and to test a material used in environmental compensation projects. The surface temperatures of the living wall, the protected and the control plot were monitored and compared to analyze the intensity of the shading mechanism. The results demonstrate that, in the early morning, the living wall prevented heat loss from the façade and, from direct sunlight, kept the protected plot's surface temperatures lower than the control plot. This difference reached up to 9.4 °C at Est (morning period) and 2.8 °C at Ist (afternoon period), as well as a maximum thermal delay of 06h30min between Est peaks. These findings show the positive influence of the living wall in winter, considering the characteristics of the Cfa climate (cold in the morning and hot during the day), expand knowledge about the thermal influence of the continuous living wall in the building and reinforce the use of living walls beyond aesthetics. |

A partir disso, este estudo experimental objetivou identificar e quantificar a influência de uma parede viva contínua nas variações das temperaturas superficiais interna e externa (Tsi e Tse) de uma fachada Leste, em período de inverno, em clima Cfa. O jardim teve o diferencial de ser construído com placas de reciclado Tetrapak® tanto para diferenciá-lo das demais tecnologias já estudadas, quanto para testar um material utilizado em projetos de compensação ambiental. As temperaturas superficiais da parede viva, da parcela protegida e da parcela controle foram monitoradas e comparadas para análise da intensidade do mecanismo de sombreamento. Os resultados demonstram que no início da manhã a parede viva impediu a perda de calor pela fachada e, a partir da incidência solar direta, ela manteve as temperaturas superficiais da parcela protegida menores em relação à controle. Essa diferença atingiu até 9,4 °C na Tse (período da manhã) e 2,8 °C na Tsi (período da tarde), assim como, um atraso térmico máximo de 06h30min entre os picos de Tse. Esses achados evidenciam a influência positiva da parede viva no inverno, considerando as características do clima Cfa (frio de manhã e quente durante o dia); ampliam o conhecimento sobre a influência térmica da parede viva contínua na edificação e reforçam o uso das paredes vivas para além da estética.Universidade Estadual de Campinas2023-06-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/867084110.20396/parc.v14i00.8670841PARC Pesquisa em Arquitetura e Construção; Vol. 14 (2023): Continuous publication; e023013PARC Pesquisa em Arquitetura e Construção; Vol. 14 (2023): Publicação contínua; e023013PARC Pesquisa em Arquitetura e Construção; v. 14 (2023): Publicação contínua; e0230131980-6809reponame:PARC (Campinas)instname:Universidade Estadual de Campinas (UNICAMP)instacron:UNICAMPenghttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/8670841/32053Brazil; ContemporaryBrasil; ContemporâneoCopyright (c) 2023 PARC Pesquisa em Arquitetura e Construçãohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCruciol-Barbosa, MuriloFontes, Maria Solange Gurgel de CastroAzambuja, Maximiliano dos Anjos2023-12-29T21:22:07Zoai:ojs.periodicos.sbu.unicamp.br:article/8670841Revistahttp://periodicos.sbu.unicamp.br/ojs/index.php/parcPUBhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/oai||parc@fec.unicamp.br1980-68091980-6809opendoar:2023-12-29T21:22:07PARC (Campinas) - Universidade Estadual de Campinas (UNICAMP)false |
