Egress Modelling
Egress modelling uses computer simulation software to analyze occupant movement and evacuation behaviour within a building during an emergency.
It offers a performance-based alternative to prescriptive egress calculations for complex building layouts.
Why It’s Needed
This service is typically used for large or complex buildings such as stadiums, transit stations, high-rises, and assembly occupancies, where prescriptive egress requirements are difficult to apply directly or a more precise evacuation analysis is needed to support an alternative solution.
Our Approach
We develop occupant evacuation models using specialized simulation software, incorporating building geometry, occupant characteristics, and fire/smoke conditions where relevant, to assess evacuation time and identify potential bottlenecks.
Scope of Work
- Development of a building-specific egress model
- Occupant characteristic and load assumptions
- Evacuation simulation runs
- Identification of egress constraints and design recommendations
- Reporting of results and conclusions
Applicable Codes, Standards, and References
- OBC, MBC. NBC
Benefit
Provides a detailed, defensible basis for egress design in complex buildings, supporting alternative solutions and AHJ approval.
