BIM-based building physics modelling of ventilated façade systems

Abstract

In this study, a BIM-based building physics modelling of a ventilated façade of a multistorey residential building was made to obtain the thermal performance of the construction. The workflow is performed in an open BIM environment using Archicad to create the model and Comsol Multiphysics for performing the numerical simulations. After creating a suitable workflow and performing the finite element simulations, we determined the thermal impact of the supporting brackets and the dowels securing the thermal insulation, respectively. We also calculated the thermal performance using simplified methods according to standards to evaluate the BIM-based results.
