Building codes specify means of egress mainly in terms of requirements concerning the arrangement of means of egress, egress capacities and maximum travel distances, derived on an empirical basis. Alternative solutions are increasingly substantiated by egress simulations and resulting evacuation times. Indicative values for the appraisal of calculated times are available, however, they refer to flow times only and no systematic evaluation of evacuation times for means of egress complying with code requirements has yet been performed.
Within this project evacuation times are calculated for examples complying with German building code requirements. The intention was to investigate, whether current code specifications render reasonable results when they are translated into the time domain and whether specified evacuation times may be used as superior criteria for a performance based design of means of egress.
