The growing demand for sustainable, energy-efficient buildings underscores the need for integrated modelling and simulation tools that support informed decision-making during early design stages. Among these, simulation of building physics performance, particularly acoustic analysis, has emerged as a critical focus area. Addressing multi-domain perspectives poses challenges, primarily due to interoperability issues and the varied data management approaches across specialized tools. This paper presents a workflow for integrating acoustic performance calculations within a BIM (Building Information Modeling) model. It details the development of an acoustic assessment tool in Grasshopper, utilising Rhino.Inside Revit, for preliminary evaluations of facade acoustic insulation. The tool supports the selection of transparent and opaque elements while accounting for potential conflicts with other performance criteria, such as thermal and lighting properties. Developed as part of the iclimabuilt project, this workflow aims to advance decision-making through seamless interoperability, enhancing efficiency, sustainability, and architectural performance outcomes.
