Combined Stair and Lift Lobby Pressurization Shaft.
Combined Stair and Lift Lobby Pressurization Shaft.
(OP)
I would like to ask, if it is possible to combine in one shaft the Lift Lobby and Stair Pressurization? The Two areas are adjacent to each other and a shaft is in the mid of it. I would like to used the shaft (masonry shaft) as the conveyor of the pressurized air that will serve both areas. Any code violations?
Thanks for your help in advance.

Most codes require stair pressurization, not elevator shaft pressurization.
The stair should be enclosed with fire rated construction and pressurized depending in the levels served.

I believe that the air flow rate to pressurize both stair and elevator lobby with the same system would be too high. There is the possibility of many doors open that difficults pressurization.
I would go with stair pressurization and elevator lobby fire rated enclosure.
