This episode delves into the financial aspects of fire safety in building design, highlighting the balance between cost and effectiveness. My guests - prof. Thomas Gernay and Chenzi Ma from Johns Hopkins University share insights from their NIST-sponsored research project on cost-benefit analysis and loss estimation for structural fire safety. In the discussion, we explore the differences between prescriptive and performance-based approaches, discussing insights from a comprehensive analysis of over 130 structures and how to better allocate resources for passive fire protection measures.

In this episode, we cover:
• Understanding fire safety costs in construction
• Insights on prescriptive vs. performance-based design
• The importance of maintenance and lifecycle cost assessments
• Analyzing fragility functions for predicting fire damage
• Cost dynamics across different building occupancy types
• Future developments for implementing this analytical framework in practice
