Resumo: | Climate change points to a future scenario of heterogeneous projections of terrestrial warming. In this context, buildings are responsible for a significant portion of the global energy consumption, aimed at maintaining the thermal comfort of the occupants, especially when it cannot be obtained through passive conditioning strategies. The objective of the research was to compare the impact of climate change on comfort, thermal performance and energy consumption of a naturally ventilated multifamily building proposing to adapt the windows and vertical envelope system to the local climate. Manaus, Vitória, Brasília and Porto Alegre were selected to carry out simulations of a Real Model - representative of existing buildings - and an Optimized Model - which incorporates recommendations from NBR 15575 and passive conditioning strategies. The climatic scenarios considered were the present (based on the historical period 1961-1990) and future (2020s, 2050s and 2080s). The results showed that, in future scenarios, there is an increase in the number of hours of thermal discomfort due to heat, both in the Real Model and in the Optimized Model. In general, the Optimized Model minimized thermal discomfort, mainly in the current period and in the 2020 time slices, but it showed, from the 2050s, a reduction in the ability to provide comfort, considering the adoption of passive conditioning strategies. It is ratified that NBR 15575 could include parameters for future climate projections, adapting buildings to the climate and containing anthropic climate changes. |

Nesse contexto, os edifícios são responsáveis por uma parcela significativa do consumo energético global destinado à manutenção do conforto térmico dos ocupantes, especialmente quando não pode ser obtido por meio de estratégias passivas de condicionamento. O objetivo da pesquisa foi comparar o impacto das mudanças climáticas no conforto, no desempenho térmico e no consumo energético de uma edificação multifamiliar naturalmente ventilada à sua proposta de adaptação das esquadrias e dos sistemas de vedação vertical ao contexto climático local. Foram selecionadas Manaus, Vitória, Brasília e Porto Alegre para a realização de simulações de um Modelo Real (MReal) – representativo de edificações existentes – e de um Modelo Otimizado (MOt) – que incorpora recomendações da NBR 15575 e estratégias de condicionamento passivo. Os cenários climáticos considerados foram o período atual (com base na série histórica 1961-1990) e futuros (2020s, 2050s e 2080s). Os resultados demonstraram que, em cenários futuros, há aumento no número de horas de desconforto térmico por calor, tanto no MReal quanto no MOt. Em geral, o MOt minimizou o desconforto térmico por calor, principalmente no período atual e na parcela de tempo de 2020s, mas apresentou, a partir de 2050s, redução na capacidade de proporcionar conforto, considerando a adoção de estratégias passivas de condicionamento. Ratifica-se que a NBR 15575 poderia incluir parâmetros de projeções climáticas futuras para adequação das edificações ao clima e contenção das alterações climáticas antrópicas.Universidade Estadual de Campinas2022-09-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/866583210.20396/parc.v13i00.8665832PARC Pesquisa em Arquitetura e Construção; Vol. 13 (2022): Continous publication; e022025PARC Pesquisa em Arquitetura e Construção; Vol. 13 (2022): Publicação contínua; e022025PARC Pesquisa em Arquitetura e Construção; v. 13 (2022): Publicação contínua; e0220251980-6809reponame:PARC (Campinas)instname:Universidade Estadual de Campinas (UNICAMP)instacron:UNICAMPenghttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/8665832/30049Brazil; ContemporaryBrasil; ContemporâneoCopyright (c) 2022 PARC Pesquisa em Arquitetura e Construçãohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMachado, Jéssica de MelloMalta, Nayara Salera Bussolotti, Victor Moura Ferrão, Ariane Louzada SassoNico-Rodrigues, Edna AparecidaAlvarez, Cristina Engel de 2022-10-07T18:38:31Zoai:ojs.periodicos.sbu.unicamp.br:article/8665832Revistahttp://periodicos.sbu.unicamp.br/ojs/index.php/parcPUBhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/oai||parc@fec.unicamp.br1980-68091980-6809opendoar:2022-10-07T18:38:31PARC (Campinas) - Universidade Estadual de Campinas (UNICAMP)false |
