Evacuation Modelling

All the fire and life safety codes (local and international) provide the methodology to size the egress element for the building based on the data derived from research. This method of sizing the egress system is simple to use for buildings but does not resemble the practical emergency evacuation. We undertake complex egress analysis to predict the crowd/ higher density areas during evacuation, to assess the best use of the egress components and to estimate the evacuation time to a place of safety. Our analysis can be used to substantiate whether the provided exit capacity is sufficient or extended travel distance or reduces the size of the egress components (e.g., staircase width).

We also utilize evacuation modelling to determine the available safe egress time (ASET) for a building’s occupants during emergencies. Our specialized expertise lies in accurately calculating ASET through advanced evacuation modelling techniques. ASET represents the window of time during which occupants can evacuate to a safe location before conditions become hazardous, making it a pivotal factor in designing effective evacuation strategies coupled with the result of fire and smoke modelling.

Our ASET calculation process involves a meticulous analysis of various factors that influence evacuation dynamics. We consider fire growth patterns, smoke development, occupant movement, exit capacities, even potential obstacles within the building layout and human behaviour during emergencies. By integrating this information into our advanced simulation software, we generate precise estimates of the time available for safe evacuation. This analysis is essential for developing performance-based fire engineering designs for buildings.
