  The simulation of evacuation of pedestrians from skyscraper is a situation
where the symmetry analysis method and equations of fluid dynamics finds to be
very useful. When applied, they strongly reduce the number of free parameters
used in simulations and in such a way speed up the calculations and make them
easier to manage by the programmer and what is even more important, they can
give a fresh insight into a problem of evacuation and help with incorporation
of "Ambient Intelligent Devices" into future real buildings. We have analyzed
various, simplified, cases of evacuation from skyscraper by employing improved
"Social Force Model". For each of them we obtained the average force acting on
the pedestrian as a function of the evacuation time. The results clearly show
that both methods mentioned above, can be successfully implemented in the
simulation process and return with satisfactory conclusions.
