Generative design of terraced concert hall – a case study of Taipei music and library centre

The terraced concert hall offers a wide range of design options. Yet the knowledge barrier within a design team makes it difficult to effectively deliver a design that satisfies both the needs of creativity and acoustics. The study aims to explore the integration of generative parametric design collaboration workflow into the design of terraced concert halls and apply the cumulative results of the pilot study to the Taipei Music and Library Centre design competition. We propose an enhanced collaborating model between architects and acoustic consultants, integrating geometric design with acoustic verification in concert hall design. This cooperating model embraces and integrates three key steps: defining basic parameters and reference geometries, efficiently generating and composing geometric elements, and conducting geometric and acoustic statistical assessments. This design strategy enables integration of diverse viewpoints, covering both the acoustics within the hall and the space integration with the surroundings. The outcome is a terraced concert hall with an acoustic performance comparable to traditional shoebox-shaped halls.
