Adtranz designed an innovative energy management system for the new IC-2000 coaches for Swiss SBB. One of the targets was a smoothened operation of air-conditioning, i.e. keeping the air-conditioning system from over-reacting to short-term variations in outside climatic conditions. For example: When the train enters a tunnel, external temperature sensors recognize the steep temperature change as transitory and the control keeps the air-conditioning system from turning on the heating.

The same system foresees excess ventilation in the case of overheating due to sunshine through windows.
