not only for its innovative architecture but also for its functionalism which
means presenting innovative solutions to the most common problems faced
by the design of metro stations in Egypt : egenormous consumption of
energy for lighting and ventilation using the solar cells roof sand exploiting
the resulting energy from the friction between the wagon and rails, rushing
air in front of the wagon when it entered the side- walk moving the fans
fixed down the sidewalk to generate power for the station. As for
ventilation , distributing air to the interior courtyards allow moving airas a
