Staircase Pressurization

In tall buildings, a fire exit staircase is recommended to be maintained at a recommended pressure range. Adequate positive pressure should be maintained such that smoke should not enter the staircase and at the same time, pressure should not be large enough to prevent the occupant from opening the door. CFD tools help to accurately predict the pressure variation in the staircase and It helps to optimize the Staircase design for the location of the pressure sensor, pressurization grill, pressure relief damper size
