The growing concerns of global society on the consequences of climate changes and how to address them are shaping the way of living. In the construction industry, one of the greatest contributors to the total environmental impacts, this issue is particularly relevant.
In this sense, the potential of Building Information Modelling (BIM) on sustainable construction is being increasingly acknowledged by society and in business-to-business relationships. BIM stores and analyses the project’s information, being a unique tool with potential to perform several types of analysis, e.g. environmental sustainability analysis.
In this study, the authors validate an existing tool for a semi-automatic BIM-LCA (Life Cycle Assessment): Tally (Revit’s plugin). In order to perform this validation, the authors use a simplified building assembly consisting of external walls with environmental information (LCA based on site-specific data and Environmental Product Declarations - EPD) and compare these results with Tally’s. By doing so, the authors answers the questions: i) do existing BIM-LCA tools offer an accurate environmental assessment of the projects?; ii) If not, how should that problem be addressed?
In the end, this study contributes to the valuation of existing environmental sustainability tools integrated with BIM and estimates/judges/shows how suitable they are to answer the needs of the construction industry.
