Abstract: An elevator system (20) is provided including a hoistway (22) and an elevator car (24) movable within the hoistway (22) between a plurality of landings (26). The elevator car (24) includes at least one air scoop (70) configured to fluidly couple an interior of the elevator car (24) to the hoistway (22) such that a controlled fluid flow may pass there between. The hoistway (22) may or may not include a ventilation opening (50) configured to couple the hoistway (22) to an air source disposed outside of the hoistway (22).

Abstract: An elevator system 20 is provided including a hoistway 33 that does not include a ventilation opening 50 configured to fluidly couple to the hoistway to an air source disposed outside of the hoistway. An elevator car 24 is movable within the hoistway between a plurality of landings 27. A plurality of landing doors 26 is arranged at each of the plurality of landings. The landing doors are movable between an open position and a closed position. The plurality of landing doors is configured to allow a defined amount of fluid flow there through when in a closed position.

Abstract: An exemplary method is useful for controlling movement of an elevator car in an elevator system that includes a machine that selectively moves the elevator car and a machine brake that selectively resists movement of the elevator car. The method includes determining whether the elevator car is near a landing and determining whether a door of the elevator car is open. A desired operation includes desired movement of the elevator car while the elevator car is near the landing and the door is open. A determination is made whether the elevator car moves other than according to the desired movement. The machine brake is applied for stopping movement of the elevator car responsive to elevator car movement other than the desired movement while the elevator car is near the landing and the door is open.
