A method for using an elevator system in a building having several vertically spaced floors (F1, F2, Fi, Fii), said elevator system comprising one or more vertically traveling elevator cars (C1,C2) serving one or more of said floors (F 1, F 2, Fi, Fii), said floors comprising at least - a first floor (F 1), - a second floor (F 2), and - a plurality of intermediate floors (Fi, Fii) positioned vertically between the first and second floor (F1, F2), the elevator system being configured to have several modes, including at least a normal operating mode and an evacuation operating mode, in which normal operating mode a car of the elevator system is used to serve a first set of floors, and in which evacuation operating mode said elevator car is used to serve a second set of floors different from said first set of floors; the method comprising evacuating passengers from the first floor (F 1) to the second floor (F 2), the evacuating comprising changing the mode of the elevator system from the normal operating mode to the evacuation operating mode; and determining the second set of floors to include the first floor (F 1) and an intermediate stop floor (Fi) from amongst the plurality of intermediate floors (Fi, Fii) or a subset thereof; characterized in that the method comprises transporting a load of passengers from the first floor (F 1) with said elevator car without intermediate stops to said intermediate stop floor (Fi) by moving an elevator car to the first floor; and thereafter receiving a load of passengers from the first floor into the elevator car; and thereafter moving the elevator car without intermediate stops to said intermediate stop floor (Fi); and thereafter unloading the load of passengers received from the first floor to the intermediate stop floor (Fi); and repeating one or more times said transporting a load of passengers from the first floor (F 1); and after one or more of said transporting, transporting passengers from said intermediate stop floor (Fi) with an elevator car (C1,C2) to the second floor. - a first floor (F 1), - a second floor (F 2), and - a plurality of intermediate floors (Fi, Fii) positioned vertically between the first and second floor (F1, F2), the elevator system being configured to have several modes, including at least a normal operating mode and an evacuation operating mode, in which normal operating mode a car of the elevator system is used to serve a first set of floors, and in which evacuation operating mode said elevator car is used to serve a second set of floors different from said first set of floors; the method comprising evacuating passengers from the first floor (F 1) to the second floor (F 2), the evacuating comprising changing the mode of the elevator system from the normal operating mode to the evacuation operating mode; and determining the second set of floors to include the first floor (F 1) and an intermediate stop floor (Fi) from amongst the plurality of intermediate floors (Fi, Fii) or a subset thereof; characterized in that the method comprises transporting a load of passengers from the first floor (F 1) with said elevator car without intermediate stops to said intermediate stop floor (Fi) by moving an elevator car to the first floor; and thereafter receiving a load of passengers from the first floor into the elevator car; and thereafter moving the elevator car without intermediate stops to said intermediate stop floor (Fi); and thereafter unloading the load of passengers received from the first floor to the intermediate stop floor (Fi); and repeating one or more times said transporting a load of passengers from the first floor (F 1); and after one or more of said transporting, transporting passengers from said intermediate stop floor (Fi) with an elevator car (C1,C2) to the second floor.
