While many modern buildings do not fit well with the requirements of prescriptive codes, performance-based design using Fire Modeling promotes a better understanding of how a building would perform in the event of a fire.
Through the process of performance-based design, typically, our FPEs defines the project scope, identify goals, define objectives, develop performance-based criteria, develop the scenarios and design fires, develop trial design(s) and at last evaluate the trial design.
These steps are done using computational fluid dynamics (CFD) and evacuation modeling techniques. CFD is simply a mathematical method used to predict the fire behavior and the correspondent fire protection feature, while the evacuation modeling is performed to determine the required safe egress time (RSET) in complex buildings and then comparing it with the available safe egress time (ASET) which is the output of the smoke CFD analysis for different fire scenarios.
