Abstract
This thesis investigates possible problems due to pressurization of high staircases. The main problem arising when high enclosures are not pressurized in sections in the event of fire is that an imbalance of the pressure profile in the building occurs. Pressure difference between the stairwell and adjacent rooms becomes large enough that the doors to the stairwell may be difficult to open and close. This poses problems to stairwells which both aim to be good fire compartment as well as being a safe escape route. The thesis investigates ventilation technologies and methods used today to solve the problem. Large focus is placed on theories and previous research projects carried out. Some of the solutions are also examined in the computer... (More)
