Performance-based optimal design
Historically, prescriptive building regulations have been an important component in design for fire safety in buildings. It is acknowledged that prescriptive design has resulted in the achievement of safety levels which the community appears to accept. Accordingly, it is appropriate to require that in the development of alternative designs for building fire safety and protection existing levels of protection should be maintained. However, that design approach does not generally result in the most cost-effective design solutions, nor in designs that maintain a consistent level of safety.
