Em busca de edifícios cada vez mais eficientes energeticamente, foram sendo desenvolvidas ferramentas que pudessem auxiliar nesse processo. De forma a ultrapassar a barreira dos cálculos tradicionais, a simulação computacional é uma das ferramentas que permite a análise energética com resultados mais precisos, através de uma avaliação mais complexa. Dessa maneira, engenheiros e arquitetos utilizam a simulação energética para otimizar o desempenho de energia dos edifícios, proporcionando também melhor
conforto térmico. Por trás da simulação, existem algumas metodologias que são a base de cálculo motor desse processo. Existe a metodologia BIM (Building Information Modeling), que agrega todas as propriedades do edifício, tornando-o mais perto da realidade possível, e para a especialidade da análise energética, o BEM (Building Energy Modeling) pode trabalhar paralelamente ao BIM. Como meio de
facilitar esse processo, algumas plataformas foram criadas com ferramentas projetadas especificamente para dar suporte ao BIM e BEM, como é o caso do Revit, DesignBuilder e EnergyPlus. No presente trabalho, foi desenvolvido um estudo de caso que envolve realizar a simulação energética de um edifício unifamiliar, através de programas baseados nas metodologias BIM e BEM a fim de verificar de que forma o BIM agrega a essa otimização energética e como o BEM agrega nesse processo do BIM. Além disso, também foi avaliado o fluxo de dados e informações entre os dois, já que eles trabalham paralelamente, ou seja, verificar a interoperabilidade entre ambos. Para isso, foram criados três projetos: o primeiro projeto em Revit,
o segundo em DesignBuilder, e por fim, a partir de um arquivo gbXML exportado do Revit, e importado ao DesignBuilder. Durante esse processo foram perceptíveis inúmeras diferenças entre programas, desde a modelagem e configurações energéticas, bem como o cálculo da resistência térmica total dos elementos construtivos e o cálculo das zonas térmicas, que são feitos de forma diferente entre os programas.
In the pursuit of increasingly energy-efficient buildings, tools have been developed to assist in this process. To overcome the limitations of traditional calculations, computational simulation is one of the tools that allows for more precise energy analysis through a more complex evaluation. Thus, engineers and architects use energy simulation to optimize the energy performance of buildings, also providing better thermal comfort. Behind the simulation, there are several methodologies that form the calculation engine of this process. There is the BIM (Building Information Modeling) methodology, which integrates all the properties of the building, making it as close to reality as possible, and for the specialty of energy analysis, BEM (Building Energy Modeling) can work in parallel with BIM. To facilitate this process, some platforms have been created with tools specifically designed to support BIM and BEM, such as Revit, DesignBuilder, and EnergyPlus. In this study, a case study was conducted involving the energy simulation of a single-family building using programs based on BIM and BEM methodologies to verify how BIM contributes to energy optimization and how BEM contributes to the BIM process. Additionally, the data and information flow between the two was evaluated, as they work in parallel, in other words, to verify the interoperability between them. For this purpose, three projects were created: the first project in Revit, the second in DesignBuilder, and finally, using a gbXML file exported from Revit and imported into DesignBuilder. Throughout this process, numerous differences between the programs were noticeable, from modeling and energy configurations to the calculation of the total thermal resistance of the construction elements and the calculation of thermal zones, which are done differently between the programs.
