Study of the evacuation of people in case of fire
Assessing and predicting pedestrian movement in case of fire: EOLIOS' expertise
Buildings must allow people to move freely at all times and to evacuate quickly in case of an emergency. Using simulation to optimize people flow can lead to environmental improvements and more effective fire safety design in large, busy locations , from shopping malls and train stations to airports and sports stadiums.
EOLIOS has extensive experience in computer modeling of evacuations and uses this skill to assess the theoretical movement of pedestrians in the event of a fire .
By providing a 3D output , we demonstrate how the built environment functions when a large number of people are present and offer real-time visualizations . By visualizing the geometry’s behavior, we can predict potential problems and develop design solutions to avoid them .
Simulation of the evacuation of people
EOLIOS' expertise for efficient evacuations in complex spaces
EOLIOS’ modeling system can take into account the most complex geometries , including spiral staircases and escalators. . Visit Slopes can vary from vertical ladders to gently inclined ramps. . Visit Escalators and moving walkways can also be configured.
For the most complex studies, elevators are modeled taking into account evacuation parameters. . Each elevator has a priority list of floors to be serviced . Users proceed to the nearest elevator or to a waiting area in case of an emergency evacuation. Elevators may be grouped in columns of several elevators to respond to calls from different floors and have a maximum capacity .
Individual agents for realistic simulation: Personalized profiles and behaviors
In the simulation, each agent acts individually . Each agent can have a specific profile (size, speed, preference for not taking stairs, priority, etc.) as well as specific behavior (waiting areas, affected exits, checkpoints, etc.). Each agent makes dynamic decisions influenced by its environment. Agents can react to the opening or closing of doors as well as to the formation of queues during evacuation.
The models can also accommodate people with reduced mobility , requiring assistance to move around, such as people in wheelchairs or in beds for hospitals and nursing homes.
The simulation results are presented as highly realistic videos , viewable from all angles. They can also be visualized as density maps , exit time curves , and flow rate tracking at gates , among other things.
Buildings designed to meet fire safety standards: Customized solutions
Evaluate the implications of the design on evacuation:
We distribute value by testing different building configurations in the context of a fire scenario. We Let’s combine the smoke extraction simulation analyses with the evacuation to ensure that the systems are correctly sized.
We evaluate alternative options by examining the implications of removing a staircase from a building or the effects of a fire scenario on escape routes in remote locations.
Computer modeling allows for a much more ergonomic design. in the early stages of a project, even though all buildings require safe and efficient evacuation. Some of the benefits include:
- Design – efficient layout with regard to areas such as passageways, stairs, escalators, elevators and assembly areas
- Reduce congestion and queues in key areas such as entrances and barrier systems
- Optimize – the positioning of points of sale and advertising displays in relation to foot traffic, purpose of travel, and population profile
- Facilitation – successful operational planning of access, safety and security with respect to normal and emergency circumstances
Objective of the evacuation study within the framework of fire safety
An effective combination of smoke control engineering and evacuation studies
Currently, there are no plans to offer an alternative to the standard solutions regarding the location, number, and width of evacuation routes. However, while respecting minimum regulatory requirements for evacuation, it is desirable to be able to combine evacuation studies with smoke control engineering .
To ensure the safety of people, it is necessary to assess the effectiveness of the smoke extraction system by comparing the time required to reach untenability criteria such as visibility through smoke and temperature, and the evacuation time .
The use of an evacuation analysis , which is sometimes already required for certain smoke control engineering studies, improves safety and constitutes an additional supporting document when carrying out a smoke control engineering study.
Modeling the evolution of fumes in an enclosed space
We provide the necessary justification to the inspection authorities
Justification of the design with regard to normative requirements:
Thanks to simulations of evacuation patterns combined with smoke extraction simulations, we can determine at an early stage whether smoke control systems and various natural ventilation openings are compliant. We analyze smoke pockets in trapped areas and make structural and technical suggestions to keep escape routes smoke-free. Using videos, we can illustrate the propagation of smoke gases and thus agree on the necessary measures in consultation with all those involved in the design.
We organize discussions with the inspection authorities, so as to justify the design in terms of an interpretation of the standard. Our many years of experience in major projects are particularly advantageous in this context.
