1. A method for regulating a stationary climate control system for a vehicle that includes at least one first energy source, the method comprising: determining an actual value of a climate parameter from an interior of the vehicle; generating a difference value from the actual value and a reference value; determining a projected usage time for the vehicle; determining a time interval from a current time and the determined projected usage time; determining a quantity of energy required to set the climate parameter to a desired value based on a length of the time interval and the difference value; and setting the actual value for the climate parameter within the time interval to the desired value based on the required quantity of energy and the quantity of energy available from the first energy source.
