Resumo: The incidence of solar radiation on buildings is considered one of the main factors responsible for their thermal load. Its impact will depend, among other factors, on the solar absorptance of the building's external surfaces. This paper analyzes the thermal comfort of users of a single-family ground floor house, using the ASHRAE 55/2013 methodology, in the context of three different bioclimatic zones: Curitiba (ZB1), Maringá (ZB3), and Belém (ZB8). The method comprises the following steps: selection of the typology and representative cities; selection of the absorptance values; simulations using EnergyPlus software; and analysis of the results. The results showed that the absorptance of the envelope had a significant influence on the users' thermal comfort and on the increase of the internal thermal load. Roof tiles and paints, with higher absorbance values, were responsible for an increase of up to 24.74% and 17.55% in the total number of annual hours of heat discomfort. In winter, roof tiles and paints with higher absorptance values influenced the decrease of up to 17.07% and 13.7% in the total annual hours of discomfort caused by cold. Using lower and higher absorptance is recommended for warmer and colder bioclimatic zones. Concerning regions where both heat and cold discomfort are significant, a careful choice of absorptance is recommended, considering factors such as different building systems' use of natural ventilation and shading devices, among other solutions to improve users' thermal comfort.

Este trabalho analisa o conforto térmico dos usuários de uma habitação unifamiliar térrea, pela metodologia da ASHRAE 55/2013, no contexto de três cidades classificadas em diferentes zonas bioclimáticas: Curitiba (ZB1), Maringá (ZB3) e Belém (ZB8). O método é composto das seguintes etapas: 1. Seleção da tipologia e cidades representativas; 2. Seleção dos valores de absortância; 3. Simulações através do software EnergyPlus e 4. Análise dos resultados. Os resultados demonstraram que a absortância das envoltórias apresentou influência significativa no conforto térmico dos usuários e no aumento da carga térmica interna. As telhas e as tintas, com valores de absortância mais elevados, foram responsáveis, respectivamente, pelo acréscimo de até 24,74% e 17,55% no total de horas anuais em desconforto por calor. No inverno, telhas e tintas com maior absortância apresentaram influência no decréscimo de até 17,07% e 13,7% no total de horas anuais em desconforto por frio. Conforme esperado, é recomendada a utilização de absortâncias mais baixas e altas para zonas bioclimáticas mais quentes e mais frias, respectivamente. Em relação a regiões em que tanto o desconforto por calor quanto por frio é significativo, recomenda-se a escolha criteriosa da absortância, considerando fatores como diferentes sistemas construtivos, uso de ventilação natural e de dispositivos de sombreamento, entre outras soluções, visando a melhoria do conforto térmico dos usuários.Universidade Estadual de Campinas2023-01-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionTextoinfo:eu-repo/semantics/otherapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/866820210.20396/parc.v14i00.8668202PARC Pesquisa em Arquitetura e Construção; Vol. 14 (2023): Continuous publication; e023003PARC Pesquisa em Arquitetura e Construção; Vol. 14 (2023): Publicação contínua; e023003PARC Pesquisa em Arquitetura e Construção; v. 14 (2023): Publicação contínua; e0230031980-6809reponame:PARC (Campinas)instname:Universidade Estadual de Campinas (UNICAMP)instacron:UNICAMPporhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/article/view/8668202/30953Brazil; ContemporaryBrasil; ContemporâneoCopyright (c) 2023 PARC Pesquisa em Arquitetura e Construçãohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCândido, Carolina Dieguez Dornelles, Kelen Almeida Lukiantchuki, Marieli Azoia2023-12-29T21:22:09Zoai:ojs.periodicos.sbu.unicamp.br:article/8668202Revistahttp://periodicos.sbu.unicamp.br/ojs/index.php/parcPUBhttps://periodicos.sbu.unicamp.br/ojs/index.php/parc/oai||parc@fec.unicamp.br1980-68091980-6809opendoar:2023-12-29T21:22:09PARC (Campinas) - Universidade Estadual de Campinas (UNICAMP)false
