A Revit-Based Plugin for Acoustic Performance Integration in Sus-tainable Interior Architecture

Abstract

Indoor acoustic performance is increasingly recognized as a key component of sustainable interior design, influencing occupant’s comfort, perception, and productivity. Effective acoustic analysis requires the inte-gration of geometric data, such as spatial layout, with non-geometric data, including material sound absorption properties. While early-stage analysis is essential to avoid costly retrofits, current practices rely heavily on standalone tools like ODEON Room Acoustics Software, which often limit integration with the broader design workflow. Building Information Modelling (BIM) provides a holistic platform where acoustics can be em-bedded alongside architectural, structural, and sustainability considerations. This study addresses the gap between acoustic and sustainable interior design by developing a custom Revit plugin using the Autodesk Revit API in C#. The plugin calculates reverberation time (RT60) through Sabine’s and Eyring’s formulas, extracting geometric and material data from Revit and an external material database. Results are reintegrated into the BIM model as new attributes, enabling visualization within Revit, export as .csv files, and frequen-cy-based data highlighting. Findings show that embedding acoustic analysis within BIM enhances efficiency, supports informed material selection, and enables performance-based decision-making in sustainable interior design. By integrating sound quality with sustainability goals, this approach contributes to healthier, more comfortable, and environmentally responsible interior environments.
