What is performance-based design, and when is it used?

• A. Defines outcomes and performance criteria rather than prescriptive methods; used when prescriptive code solutions are impractical or in specialized projects.
• B. Is a method for selecting contractors.
• C. Applies only to interior design aesthetics.
• D. Replaces all safety codes.

Answer: (A)

Performance-based design focuses on outcomes and performance criteria for a building or system rather than dictating exact construction methods. It’s used when prescriptive code solutions are impractical or insufficient—such as complex or innovative projects where standard rules can’t address site conditions, unusual loads, or specific performance goals. In practice, designers set targets for safety, resilience, energy, and other performance areas, and demonstrate through analysis, modeling, and testing that the design meets those targets and aligns with the code’s intent. This approach offers flexibility and optimization while still requiring compliance with safety objectives and approval from the authority having jurisdiction. It’s not about selecting contractors, nor limited to interior design aesthetics, and it does not replace safety codes; it provides an alternative path to meet code requirements.
