An elevator system ( 20 ) includes at least one vertical shaft ( 32 ) extending between at least two levels ( 24, 36 ) of a building ( 22 ). One of the levels ( 24 ) includes at least one passageway ( 28 ) between an interior of the building and the outside environment. At least one second shaft ( 40 ) extends between the other building level ( 36 ) and at least one other level within the building. The interior of the second shaft ( 40 ) is isolated from airflow on the building level ( 24 ) that includes the passageway ( 28 ) to the outside environment. Disclosed examples include enclosures ( 52 ) for isolating the first shaft ( 32 ) from airflow on at least one of the levels to which the first shaft provides access.
