Environment Modelling and Building Physics

Fire modelling

Fire modelling includes following different types of analysis and studies:
  • Emergency ventilation: assessment and optimisation of the emergency ventilation systems.

  • Safe egress path: assessment of the defined evacuation paths.

  • Safe egress time: approximation of the availabe safe time for evacuation.


Fire and smoke modelling could be performed for following building types:
  • Semi-enclosed spaces: railway and road tunnels, bus and train stations, stadia, amphitheatres and covered pedestrian walk-throughs, shopping centres and others.

  • Enclosed spaces: enclosed bus and train stations, stadia, meeting halls, shopping centres, atrium spaces, universities, schools, offices, houses, apartment buildings and others.
