Abstract

A method for controlling an elevator group including at least a first elevator and a second elevator, wherein a counterweight balance of the first elevator differs from a counterweight balance of the second elevator, the method including: controlling the elevator group; determining threshold loads for the first and second elevator separately for up and down direction, a threshold load being dependent of the counterweight balance of the corresponding elevator, wherein the threshold load being a load for which consumed energy per up-down run is approximately zero; and controlling, when allocating an elevator in response to a destination call, route determination for the first and second elevator involves minimizing a load difference from the threshold loads.
