Desenvolvimento de ferramenta BIM para avaliação prescritiva de eficiência energética integrada ao processo de projeto

Abstract

The quest for energy efficiency in buildings is largely in the architectural design, especially in the early stages of development, which being guided by bioclimatic principles, can minimize the use of artificial lighting or artificial air conditioning. The BIM allows theendesigner to carry out the most diverse types of simulation, and to design a parameterized model, which allows the fast visualization of the volumetry, the solar incidence, the application of materials, finishes, and the performance evaluation. With the quick execution of different types of simulation is possible to get better results in the performance of the building. The overall objective of the research is to develop a project support tool that allows the designer to work with the energy efficiency issue, making analyzes and simulations during the development of the architectural proposal in the initial phases of the project process. The specific objectives are: to incorporate the analysis and simulation of energy efficiency in the architectural design through the resources of the modeling information in the construction; to research methods and tools of analysis and simulation with the intention of mapping the state of the art in the theme; to provide feedback on desired performance for decision making during the design process; create mechanisms to assist in the design process, allowing to evaluate aspects of the energy performance of the various building solutions proposed. The methodology is based on Design Science Research, which bases and operationalizes the conduct of research when the goal to be achieved is an artifact. From the establishment of the problem, it is started the Systematic Review of Literature (SLR) in order to study and know the situations in the area. The following is an analysis and suggestions of possible solutions based on the established theoretical basis. The criteria and energy efficiency parameters that are used in the design and development of the IDEEA tool are defined, and a programming language study is required for this type of situation. The validation of the tool was performed through applications, simulations, and experiments, comparing the results obtained with the traditional method. After the results, it was necessary a reflection and learning from the tool production process, when the necessary adjustments are made and a new validation. Applying the tool to a group of volunteers in an extension course provided a more accurate perception of use during the design process. The IDEEA tool incorporates the energy performance in the design process, from the initial stages, giving support to the decision making, and in this way, the results found allow us to believe that the general objective of the research has been contemplated.
