The successful design of a building is a complex endeavor that requires careful consideration of multiple factors and disciplines, ultimately aiming for a holistic outcome throughout the entire process—from design and delivery to the lifespan of the building. To achieve this outcome, various aspects, such as architectural design, structural integrity, functionality, environmental sustainability, cost efficiency, and occupant comfort, must be balanced and integrated. This paper explores the relationship between acoustic performance, cost implications, and embodied carbon in internal partitions within the context of building design. It emphasises the importance of a holistic approach in considering these factors collectively and highlights the early integration of acoustic considerations, cost-effective materials and techniques, and environmental sustainability. By making informed decisions, stakeholders can optimize building outcomes by creating superior acoustic environments while minimizing costs and environmental impact. This paper aims to provide a guide for professionals, underlining the significance of a comprehensive approach in achieving optimal project results.
