Uso do BIM para certificação procel-edifica para prédios de comércio, serviço e públicos: estudo de caso do prédio da reitoria da UFSCar

Abstract

As the construction sector is responsible for more than one-third of global energy consumption, the implementation of energy-efficient buildings becomes essential. To this end, performance assessment methods have been developed, such as the Procel Edifica Label for Commercial, Service, and Public Buildings, which aims to reduce the environmental impact of constructions through the efficient management of natural resources. This study aims to verify the feasibility of directly extracting the parameters required by the Procel Edifica method from BIM software, using as a case study the Administration building of the Federal University of São Carlos, which has already been certified. Through Autodesk® Revit software, it was found that, out of the 17 required parameters, 6 are natively available in the program, 5 can be obtained through schedules, 2 must be created manually, 3 require external calculations, and 1 cannot be determined. Furthermore, the extracted results were compared with previously established values for the building, revealing that the parameters fully extractable show a good level of accuracy. However, the parameters related to the percentage of facade opening area and the average APP areas, which require supplementation by external calculations, exhibited significant discrepancies, necessitating further investigation into their proper determination. It is concluded, therefore, that the use of BIM tools can significantly aid in gathering parameters for energy labeling, although software limitations and the need for specific adaptations in the model and families prevent the full automation of the process. Nevertheless, the adoption of the BIM methodology proves to be a viable alternative to optimize data collection and support the energy assessment of public buildings.
