Abstract: The invention relates to a method for operating an elevator installed in connection with a building, particularly a high rise elevator, in which method the expected rope sway is monitored using building acceleration data obtained by means of a sensor to calculate a building sway, and whereby based on the building sway and the position of an elevator car a rope sway is estimated, which rope sway is compared with a threshold value to determine the amount of rope sway and to deduct operation measures for the elevator based on the amount of the rope sway, characterized by the succession of following steps



determining elevator car position
determining change of rope sway based on the car position and the building acceleration data
if it is concluded that rope sway is not increasing, then
calculating the number of rope sway cycles n(zca,) within a building sway period Tbuilding and
calculating a new (decreasing) rope sway amplitude x based on said number of rope sway cycles n(zca,) and a damping factor I.
