Over the past 20 years, due to the results of numerous studies in the field of fire protection in buildings, the regulations in this area have changed significantly. In existing buildings, especially those built at the beginning of the last century, it is very difficult to meet current regulatory requirements, so there is a question of safety of existing buildings in relation to newly built. In this work, considering street building of the AGG faculty, the applied active and passive fire protection measures are analyzed and compared with those that would be needed to meet the current regulatory requirements. Furthermore, by modeling the evacuation time, the time of total evacuation of all building users (maximum 2328) to a safe area outside the building, in conditions without and with adequate fire alarm, was analyzed. A total of 6 evacuation scenarios were analyzed, given the different locations of fires in the building. In addition to the number of the users of the building, the geometry the geometry of the evacuation routes was considered, but also the behavior of users in emergency situations. The obtained results show that the evacuation time can be doubled in scenarios where there is no adequate fire alarm.
