Effects of the shading in the performance of an insulated envelope building in the ZB 2
It is known that the height of the buildings, the distance between the buildings and the width of the streets, have an influence on the solar radiation absorption and buildings shading and it also affects the consumption of the buildings.

It is known that the height of the buildings, the distance between the buildings and the width of the streets, have an influence on the solar radiation absorption and buildings shading and it also affects the consumption of the buildings. Furthermore, this study aims to evaluate the surrounds shading in a very insulated building, located in the Brazilian bioclimatic zone 2. The used method is characterized by computational simulation divided into five steps: definition of the research hypothesis; analysis of the energy efficiency level considering the RTQ-R regulation; surroundings modeling and shading tracking analysis; simulation of the energy performance of the building; simulation of the thermal performance of the building; and result from analysis. Eight different possibilities of the surround configurations were simulated. The model that presented the lower consumption was the building with 6 floors surroundings, with the consumption about 26,44 kWh/m².year and with thermal comfort index about 97,72%. Hence, it was possible to observe the building shading of an insulated building even during the winter period, since that does not influence the roof, it generates a better thermal energy performance of the envelope. Sabe-se que a altura dos edifícios da vizinhança, a relação dos espaçamentos entre as edificações e a largura das vias têm influência na absorção de radiação solar direta, no sombreamento das edificações e no consumo de energia nas edificações. Assim, este estudo tem por objetivo avaliar a influência do sombreamento do entorno em uma edificação unifamiliar com elevado isolamento térmico localizada na ZBB 2. O método utilizado nesse trabalho consiste na simulação computacional de edificação com diferentes configurações de entorno, dividindo-se em 5 etapas: definição da hipótese de pesquisa; simulação do nível de eficiência energética considerando o RTQ-R; modelagem do entorno e análise do rastreamento de sombras; simulação do desempenho energético e do nível de conforto térmico; e análise dos resultados. Foram modeladas oito diferentes possibilidades de sombreamento. A configuração que apresentou o menor consumo energético e maior nível de conforto térmico foi a edificação sombreada pelo entorno de 6 pavimentos, com consumo de climatização de 26,44 kWh/m².ano e índice de conforto térmico de 97,72%. Os resultados indicaram que o elevado nível de isolamento térmico de uma edificação gera um melhor desempenho termoenergético do envelope, mesmo com o sombreamento de paredes no período de inverno.

It is known that the height of the buildings, the distance between the buildings and the width of the streets, have an influence on the solar radiation absorption and buildings shading and it also affects the consumption of the buildings. Furthermore, this study aims to evaluate the surrounds shading in a very insulated building, located in the Brazilian bioclimatic zone 2. The used method is characterized by computational simulation divided into five steps: definition of the research hypothesis; analysis of the energy efficiency level considering the RTQ-R regulation; surroundings modeling and shading tracking analysis; simulation of the energy performance of the building; simulation of the thermal performance of the building; and result from analysis. Eight different possibilities of the surround configurations were simulated.
