ojs-article-34082008-04-14T16:19:20Z Methodology for specifying and evaluating the thermal performance for single family houses, applied in Londrina-PR Uma metodologia para especificar e avaliar o desempenho térmico de edificações residenciais unifamiliares, aplicada a Londrina-PR Barbosa, Miriam Jerônimo Lamberts, Roberto Desempenho térmico; Conforto térmico; Avaliação de desempenho térmico de edificações This article presents the development of a methodology to specify and evaluate the thermal performance for one-floor single family houses. The structure for devising the methodology was: establishing the thermal comfort limits to be used, adjusting an hourly thermal simulation tool with field data from different building systems, and establishing the annual number of hours of discomfort to be accepted based on a reference building system. The methodology was applied in Londrina, PR, where a field work was carried out in different building typologies. The data was used to adjust the hourly thermal simulation tool and to confirm a thermal comfort limit. The number of hours of indoor temperature outside the comfort limits was defined as the number of annual hours of discomfort. Using the Thermal Reference Year (TRY) developed for Londrina, simulations were performed for several building system alternatives. A limit for the number of annual hours of discomfort was established based on the economics reality and on the reference building system. The evaluation by performance can be made by using an annual hourly simulation tool to quantify the hours of discomfort of a given building and comparing it to the established limit. Este trabalho consiste no desenvolvimento de uma metodologia para especificar e avaliar o desempenho térmico em edificações térreas residenciais unifamiliares. A estrutura para montagem da metodologia constou do estabelecimento de limites de conforto térmico para a população local, o ajustamento de uma ferramenta de simulação térmica horária anual frente a diferentes sistemas construtivos, e o estabelecimento do limite de horas anuais de desconforto, com base em um sistema construtivo referencial. No trabalho de campo, realizado em Londrina PR, mediu-se no verão e inverno as temperaturas internas, as características construtivas e sensações dos usuários em unidades habitacionais de sistemas construtivos diferentes. Os resultados foram usados para estabelecer os limites de conforto e ajustar a ferramenta de simulação. Com o ano climático de referência local, simulou-se várias alternativas construtivas, estabelecendo-se as horas anuais de desconforto para cada alternativa. O limite de horas anuais de desconforto aceitável foi escolhido frente à realidade econômica e ao sistema construtivo referencial. No método desenvolvido é possível fazer-se a avaliação por prescrição com base nas características térmicas do sistema construtivo referencial e por desempenho, simulando-se qualquer sistema construtivo, quantificando-se as horas anuais de desconforto e comparando-as com o limite aceitável estabelecido.

This article presents the development of a methodology to specify and evaluate the thermal performance for one-floor single family houses. The structure for devising the methodology was: establishing the thermal comfort limits to be used, adjusting an hourly thermal simulation tool with field data from different building systems, and establishing the annual number of hours of discomfort to
be accepted based on a reference building system. The methodology was applied in Londrina, PR, where a field work was carried out in different building typologies. The data was used to adjust the hourly thermal simulation tool and to confirm a thermal comfort limit. The number of hours of indoor temperature outside the comfort limits was defined as the number of annual hours of
discomfort. Using the Thermal Reference Year (TRY) developed for Londrina, simulations were performed for several building system alternatives. A limit for the number of annual hours of discomfort was established based on the economics reality and on the reference building system. The evaluation by performance can be made by using an annual hourly simulation tool to quantify the
hours of discomfort of a given building and comparing it to the established limit. |
