  This paper examines different evacuation strategies for systems where several
rooms evacuate trough the same means of egress, using microscopic pedestrian
simulation.As a case study, a medium-rise office building is considered. It was
found that the standard strategy, whereby the simultaneous evacuation of all
levels is performed, can be improved by a sequential evacuation, beginning with
the lowest floor and continuing successively with each one of the upper floors
after a certain delay. The importance of the present research is that it
provides the basis for the design and implementation of new evacuation
strategies and alarm systems that could significantly improve the evacuation of
multiple rooms trough a common means of escape.
