I have a high rise health care project where the architect is planning on using an enclosed elevator lobby as an area of refuge.  Fully sprinkled building as required and the egress stairway entrance is in the elevator lobby.

 

Question I have is should the elevator hoistway be pressurized?  Cannot find anything in the IBC or NFPA that specifically requires an enclosed elevator to be pressurized but I would think there is a concern about stack effect driving smoke from a lower floor up the hoistway into the elevator lobby.
