In my master’s thesis, I analysed the effects of the spread of smoke on evacuation. Smoke spreads differently through a building depending on the location of a fire, and this has an effect on the choice of evacuation route and evacuation exit. I compared the results for evacuation scenarios with the time of the evacuation exercise conducted in the Rectorate of the University of Ljubljana in March 2023. The BIM model of the rectorate was created in Autodesk Revit and imported into Pathfinder and Pyrosim in IFC format. Five evacuation scenarios were created in Pathfinder and analysed in terms of how the type of alarm and smoke affects the speed of evacuation. In Pyrosim, 5 fire scenarios were carried out: visibility on the evacuation routes was analysed in 4 scenarios, whereas 1 scenario was analysed in terms of how long an ordinary wooden door can stop a fire. Based on the obtained results, suggestions were made for improving fire safety in the building of the Rectorate of the University of Ljubljana.
