Resumo: | In office buildings, daylight is an important natural resource, as it is profusely available during occupied hours. However, its use can increase energy consumption for air conditioning. Therefore, combining this resource with side lighting systems and promoting its integration with electric lighting is essential to obtain an energy balance. This paper aims to analyze daylight performance and the energy consumption for lighting and air conditioning considering four types of glazing, four orientations, from window-to-wall ratios varying between 40% to 100% for bare and shaded window models in an office room located in a subtropical city in southern Brazil. The methodology was based on Useful Daylight Illuminance levels of 500 to 2,500 lx, Daylight Autonomy levels of 500 lx, and total energy consumption through simulation in DesignBuilder software. The results showed that L13 glazing is not recommended for bare and shaded windows, regardless of window orientation. M76 presented the best performance for energy consumption for West shaded windows. For the West, shading is necessary irrespective of the glazing type (except L13, whose best performance is for bare windows) from WWR 50%. M76 and M52 had the lowest total energy consumption. The findings of this study add to an understanding of the energy savings and lighting performance of different types of glazing, combined with window apertures, and solar orientations for a subtropical climate. Furthermore, the study shows that the choice of glazing depends not only on the presence of shading but also on the orientation and WWR, without a linear behavior. |

Todavia, seu uso pode aumentar o consumo de energia para ar-condicionado, portanto deve-se usar juntamente com sistemas de iluminação lateral para obter um balanço energético. O objetivo deste trabalho é analisar o desempenho de luz natural e o consumo de energia para iluminação e ar-condicionado considerando quatro tipos de vidros, quatro orientações, áreas de janela entre 40% e 100% para modelos expostos e sombreados em uma sala de escritório localizada no clima subtropical do sul do Brasil. A metodologia foi baseada nos níveis de Iluminação Útil da Luz do Dia de 500 a 2.500 lx, Autonomia da Luz do Dia de 500 lx e consumo de energia através de simulação computacional no DesignBuilder. Os resultados mostraram que o vidro L13 não é recomendado para janelas expostas e sombreadas independentemente da orientação da janela. O M76 apresentou melhor desempenho para consumo de energia em janelas sombreadas a oeste. Para oeste, o sombreamento é necessário independentemente do tipo de vidro (exceto L13 cujo melhor desempenho é para janela exposta) a partir de WWR 50%. M76 e M52 apresentaram menor consumo de energia. Os resultados obtidos contribuem para a compreensão da economia de energia e desempenho de luz natural, com diferentes vidros, aberturas de janelas e orientações solares no clima subtropical. Ainda, o estudo mostra que a escolha do vidro depende não apenas da presença de sombreamento, mas também da orientação e WWR, sem comportamento linear.Universidade Estadual de Campinas2024-01-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/867067610.20396/parc.v15i00.8670676PARC Pesquisa em Arquitetura e Construção; Vol. 15 (2024): Continuous publication; e024003PARC Pesquisa em Arquitetura e Construção; Vol. 15 (2024): Publicação contínua; e024003PARC Pesquisa em Arquitetura e Construção; v. 15 (2024): Publicação contínua; e0240031980-6809reponame:PARC (Campinas)instname:Universidade Estadual de Campinas (UNICAMP)instacron:UNICAMPenghttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/8670676/33416Brasil; ContemporâneoBrasil; ContemporâneoCopyright (c) 2024 PARC Pesquisa em Arquitetura e Construçãohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessGabriel, ElaiseGrigoletti, Giane de CamposMeller, GabrielaZambonato, Bruna2024-07-03T18:43:59Zoai:ojs.periodicos.sbu.unicamp.br:article/8670676Revistahttp://periodicos.sbu.unicamp.br/ojs/index.php/parcPUBhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/oai||parc@fec.unicamp.br1980-68091980-6809opendoar:2024-07-03T18:43:59PARC (Campinas) - Universidade Estadual de Campinas (UNICAMP)false |
