Aspects of the present invention provide an approach for controlling energy generation by an airflow originating from a moving elevator cabin. Wing pressure pads are positioned outside the elevator cabin extending to walls of the elevator shaft for preventing an airflow in the elevator shaft from above the elevator cabin to an area in the shaft below the elevator cabin. The elevator shaft is pressure-tight, and the elevator shaft has, at one end of the elevator shaft, an air conduit in which a first power generator stage having a propeller-driven electrical power generator is positioned. The method further intercepts a floor selection for the cabin and disables the power generators if a floor difference from a current position of the elevator cabin to a target position of the elevator cabin is below a predefined threshold value.
