Analysis of the early-design timber models for sound insulation analysis

Timber construction is characterized with its high circularity and sustainability. However, such construction requires a careful evaluation of sound insulation between the different building zones. Currently, acoustic analysis is performed after the design is already detailed, which requires a substantial amount of time and effort to improve the design. Additionally, thus far, performing sound insulation analysis involves manual extraction and processing of building information, which is an error prone task. Hence, this paper proposes a framework for establishing a seamless workflow between building models and acoustic analysis tools across the design phases. In more detail, the junctions between the different elements are extracted and analysed to identify the corresponding acoustic junction types, with the help of topological reasoning and logical rules. The proposed approach was evaluated via a prototypical implementation, where the different possible junction types were extracted successfully.
