“Crowd Control” inside Building Information Modeling (BIM) for Building Evacuation and Hazard Simulation by SIEMENS

 

Benefits from research activities:

The “Crowd Control” application for pedestrian stream simulation leads to:

  • safe building model in early design phase;
  • validation of evacuation concepts for various hazards;
  • discovery of bottle-necks and critical situation;
  • optimized evacuation routes for various building conditions;
  • dynamic routing execution with sophisticated algorithms calibrated to real data.

Evacuation modeling

In cases a hazard appears people move instinctively away from danger. In this situations effective emergency evacuation of building occupants or pedestrians in the surrounding is a cornerstone to minimize serious harm to human life.
Pedestrian stream simulations nowadays considers measures to evaluate and mitigate risks in critical situations. Buildings can be composed with  focus on occupant safety, making use of virtual pedestrian stream simulation. With assistance of a simulation tool,  professional operators can run through multiple “what-if” scenarios  with results to gain experience for situations that are impossible in real to gather empirical data.

Hazard Simulation

In this project, we evaluate how down-time after disasters in urban and building infrastructures can be minimized through increased resilience or means of fast recovery. We propose different simulation models, as part of a virtual building management system (vBMS), which allows the simulation and therefore the analysis of different disaster impacts (by category: fire, flooding, explosion). These hazard simulations are significantly relevant for the design, construction and operation of larger building complexes embedded into an urban infrastructure. They provide a basis for recommendations on how to improve resilience sensor-based building management systems. This new type of virtual vBMS will be used for an experimental performance analysis of multifunctional sensing elements regarding relevant loading scenarios. The results of coupling hazard and person stream simulations shown in the video below are valid for a variety of buildings, not only to the specific showcase scenario developed by the ELASSTIC consortium.
