BIM-Based Energy Analysis and Sustainability Assessment—Application to Portuguese Buildings

Buildings are responsible for several negative impacts on the environment, most of them related to nonrenewable energy consumption, increasing concern regarding buildings efficiency. In this context, computer software has been used estimate needs built and Building Information Modelling (BIM) methodology can be simplify process. This study aims validate a BIM-based framework streamline analysis Portuguese buildings, based method national regulation thermal performance residential buildings. Currently, designers need spend considerable time assessing all building characteristics performing mandatory calculations analysis. It is also intended link results simulation with Sustainability Assessment method—SBToolPT-H. The purpose demonstrate how it possible benefit from approach simultaneously improve sustainability during design stage. To do so, different case studies were modelled in Autodesk Revit exported BIM tool perform validated against official assessment successfully assess SBToolPT-H efficiency category. research outcomes provide teams reliable develop projects while enhancing sustainability. increases knowledge about integration providing new insights complete integration.
