In the article the real fires with façade systems have been examined, the causes of fire and the location of ignition sources have been considered. This analysis showed that fires occur during the mounting of façade systems. In this regard, a fire scenario in the reconstructing building has been considered, and a graphical report has been presented. The graphical report shows that in the event of fire in the office building with façade systems and smoke clear stairway marked as N1, a smoke free zone is blocked by the hazardous fire factors earlier than occupants are able to evacuate through it. So probability of safe and in time evacuation should be taken as equal to 0 in calculations, and therefore the value of fire risk exceeds the value that is specified in the existing fire safety standards.
