Ferramentas de avaliação de ciclo de vida integradas a plataformas BIM: estudo de caso de edificação unifamiliar

Abstract

In the search for environmental management methods that can mitigate the significant impact of building construction, Life Cycle Assessment (LCA) is found. The integration of LCA software to Building Information Modelling (BIM) has been showing promising results regarding the possibilities of building sustainability enhancement, mainly in the early stages. This project aimed to evaluate the potentialities and limitations of LCA tools integrated to BIM platforms, through a comparison of the results of an LCA elaborated using the traditional method and LCA software results. Findings indicated advantages in the execution of LCAs through BIM-integrated software, regarding time consumed and complexity of the process. Limitations found, however, showed that the impact categories’ results are not representative, given the restrictions related to scope, database and methodology customization. New developments are necessary to allow the adaptation of methods to different situations, reducing the specificity of the data and calculations used.
