Building information modeling (BIM) have had a growing impact on the construction industry in recent years. The use of digital building models for planning is already a reality in specialized areas such as MEP (mechanical, electrical, and plumbing systems). This is not yet the case in the domain of building acoustics. Thus the analysis of building acoustics still involves manual extraction and processing of building information, which is an error prone task.BIM methods which are integrated into everyday working life must be based on an open data format to guarantee the independence of planners from fixed software manufacturers. It is also important to enhance the understanding of digital building models to understand the requirements, limitations, and possibilities of the methodology.This paper explains how a digital building model can be used for the planning of building acoustics. It proposes a framework for establishing a seamless workflow between digital building models and acoustic analysis defining the requirements for open data formats to enable valuable data extraction. Furthermore, it will demonstrate how prediction data can be stored in the building model creating an acoustical data model. The chosen approach is based on an open BIM methodology relying on industry-wide data standards.
