Which design approach emphasizes performance criteria over prescriptive details to handle unusual or complex buildings?

• A. Prescriptive design
• B. Performance-based design
• C. Aesthetic-driven design
• D. Economy-first design

Answer: (B)

This item tests understanding of design approaches by whether safety outcomes drive the solution rather than following fixed rules. The described method centers on meeting defined performance criteria and lets you decide how to achieve them, which is the essence of performance-based design. It’s especially useful for unusual or complex buildings where a prescriptive checklist may be impractical or insufficient, because you can tailor fire protection strategies to the building’s geometry, occupancy, materials, and risk and demonstrate compliance through analysis, modeling, or scenario testing. In this approach, outcomes such as safe egress within a required time, structural integrity during a fire, effective compartmentation, and reliable detection and suppression are what matter, not whether every detail matches a prescriptive detail. By contrast, prescriptive design sticks to specific rules, aesthetic-driven design focuses on appearance, and economy-first design prioritizes cost over safety outcomes.
