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 excessive rope sway and to deduct operation measures for the elevator in order to counteract a determined excessive rope sway. According to the invention a succession of following steps is performed: determining a movement profile for the elevator car by means of an elevator controller predicting the elevator car position based on the movement profile calculating the estimated rope sway based on the predicted car position and the building acceleration data.
