Is this a ‘protected shaft’ or is it fire sealed at each compartment? You state that at each floor there is a door, not taking fire regulations into account, if a door is fitted the space behind is no longer a duct and as such does not need venting. I have had this confirmed during a Gas Safe site visit,

As Kim has stated you may also need to look at pipe construction and joining method for suitability in escape routes. Consideration into the use of Trac-Pipe or similar, providing no joints, may alleviate the ventilation requirements.
