Performance-based design is an approach to architectural and engineering design that focuses on achieving specific performance objectives, such as energy efficiency, sustainability, safety, and comfort. This methodology involves using advanced analytical tools and simulations to assess how a building will perform in various scenarios, allowing designers to optimize the building's performance based on data-driven insights. Performance-based design can help create buildings that are more efficient, sustainable, and resilient to various external factors, ultimately leading to better outcomes for both the building occupants and the environment.
