The concept of staircase pressuriation is to make positive pressure in staircase.
This is safety standard this is adopted in all high rose duildings ( NFPA standard)
This is used during fire in the building for people to evacuate through staircase to prevent fire / smoke entering staircase case area & to maintain positive pressure
