Traditional Solution
The problem of over pressurization has been traditionally addressed by the installation of a mechanical pressure relief (barometric) damper in the stairwell wall. This approach limits maximum pressure but is wasteful of fan energy, difficult to maintain and effected by wind pressure on the building.
