Method for optimizing energy use in vehicles comprising an air-circulation and -recirculation system, the method comprising the steps of measuring a carbon dioxide level of vehicle cabin air, a relative humidity level of cabin air and at least one temperature of at least one window, providing the measured carbon dioxide level, the relative humidity level and the temperature to a processing unit, providing a desired cabin temperature and an indexed optimal carbon dioxide level to the processing unit, calculating deviation of the measured cabin air carbon dioxide level from the indexed optimal carbon dioxide level, calculating optimal cabin air relative humidity level based on the desired cabin temperature, and, based on the calculation, determining the optimal rate at which to provide outside air to the cabin to achieve the calculated optimal cabin air relative humidity level and the indexed optimal carbon dioxide level, determining the recirculation rate required to provide outside air to the cabin at the determined optimal rate and providing instructions to an air-circulation and -recirculation control unit to provide air to the cabin of the vehicle at the optimal rate.
