Integrating generative parametric design workflow in the terraced concert hall design process

Abstract

Compared to shoe box halls, terraced concert halls are popular due to their proximity to the stage and expressive design. However, its complex geometry requires delicate adjustments during the design process to effectively deliver a design that satisfies both the needs of acoustics and creativity. The study aims to explore the integration of generative parametric design workflow into the design of terraced concert halls and apply the workflow to an actual competition project. This workflow consists of three steps: defining basic parameters and reference geometries, generating and composing geometric elements with synchronized acoustic and geometric verification, and conducting performance evaluation of the results. The workflow enables integration of diverse viewpoints for the competition project, covering both the acoustics of the concert hall and the spatial integration with the surroundings. The outcome is a multi-layered, terraced concert hall with acoustic performance comparable to a traditional shoebox hall, and a metaphorical image of the topography of the city in which the concert hall is located.
