Resumo: | The use of daylight in buildings is an important design strategy since it minimizes energy consumption with electric lighting and provides greater visual quality for its users. However, this strategy can result in excessive thermal gains and glare, causing thermal discomfort in work environments. In order to seek a combination between visual quality and good thermal, energy and daylight performance, this study analyzes the influence of the type of shading device and type of glazing, applied to a commercial building with a glazed facade, located in regions of tropical climate. The building without the use of shading device is also included in the analysis, as a reference. Computer simulations are performed with Daysim and EnergyPlus softwares considering the building’s west facade. When considering the type of glazing parameter, the models that present the best behavior are those with common glazing. When results between the types of shading devices are compared, it can be seen that models with vertical shading devices have much higher values of solar radiation rate than models with horizontal shading devices, bringing benefits of higher levels of daylight to the environment. The results, considering the number of hours in comfort conditions, indicate that the horizontal shading device model with laminated glazing in green color is the most suitable, since it has the lowest energy consumption and more hours of comfort. It is noteworthy, as contribution of the present work, more suitable models of shading devices are obtained for designing shading devices, applied to glazed facades in tropical climate regions. |

Porém, essa estratégia pode resultar em ganhos térmicos excessivos e ofuscamento, causando desconforto térmico em ambientes de trabalho. No intuito de buscar uma combinação entre qualidade visual e bom desempenho termoenergético e lumínico, analisa-se nesse estudo a influência do tipo de brise soleil e tipo de vidro, aplicados a uma edificação comercial com fachada envidraçada, localizada em regiões de clima tropical. Inclui-se na análise a edificação sem o uso do brise soleil, como referência. São realizadas simulações computacionais com os programas Daysim e EnergyPlus considerando-se a fachada oeste da edificação. Ao considerar o parâmetro tipo de vidro, os modelos que apresentam melhor comportamento são aqueles com vidro comum. Comparando-se os resultados entre os tipos de brises percebe-se que os modelos com brise vertical possuem valores mais elevados de taxa de radiação solar do que os modelos com brise horizontal, trazendo benefícios de maior luz natural ao ambiente. Os resultados, considerando-se as horas de conforto do usuário, indicam que o modelo de brise horizontal com vidro laminado na cor verde apresenta-se como o mais adequado, visto que possui o menor consumo de energia e mais horas de conforto. Ressalta-se, como contribuição do presente trabalho, a obtenção de modelos de brises mais adequados para projetos de brises aplicados em fachadas envidraçadas em regiões de clima tropical.Universidade Estadual de Campinas2023-01-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/866753810.20396/parc.v14i00.8667538PARC Pesquisa em Arquitetura e Construção; Vol. 14 (2023): Continuous publication; e023001PARC Pesquisa em Arquitetura e Construção; Vol. 14 (2023): Publicação contínua; e023001PARC Pesquisa em Arquitetura e Construção; v. 14 (2023): Publicação contínua; e0230011980-6809reponame:PARC (Campinas)instname:Universidade Estadual de Campinas (UNICAMP)instacron:UNICAMPporhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/8667538/30926Região de clima tropical; ContemporaryRegião de clima tropical; ContemporâneoCopyright (c) 2023 PARC Pesquisa em Arquitetura e Construçãohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDias, Luma de SouzaSouza, Henor Artur deGomes, Adriano PintoCaetano, Lucas FonsecaCamargos, Bruno Henrique Lourenço Tribess, Arlindo2023-12-29T21:22:10Zoai:ojs.periodicos.sbu.unicamp.br:article/8667538Revistahttp://periodicos.sbu.unicamp.br/ojs/index.php/parcPUBhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/oai||parc@fec.unicamp.br1980-68091980-6809opendoar:2023-12-29T21:22:10PARC (Campinas) - Universidade Estadual de Campinas (UNICAMP)false |
