What is a performance-based code?

A performance-based code establishes requirements for the outcome or performance of a system without prescribing specific methods or materials to achieve that outcome. This type of code allows for greater flexibility and innovation in design and construction, as it encourages engineers, architects, and designers to find solutions that satisfy the established performance criteria, rather than mandating a one-size-fits-all approach.

This approach is particularly useful in complex projects where traditional prescriptive codes may not adequately address unique conditions or advancements in technology. By focusing on the end results—such as ensuring life safety, property protection, and environmental sustainability—performance-based codes can accommodate a wider variety of solutions, fostering creativity and potentially improving safety outcomes.

In contrast, codes that specify exact methods and materials are prescriptive in nature and may not allow for the same level of innovation. Limits to fire prevention or applicability only to residential buildings do not align with the broad scope and intent of performance-based codes.
