The invention relates to a method for adjusting temperatures of a built structure provided with a thermal adjustment system configured to adjust the built structure to a predetermined living temperature. Said method includes implementing, via a data processing module, the steps of: (a) detecting absence of a user, (b) sending, to said system, a limiting instruction whereby said system interrupts adjustment to the living temperature; (c) estimating a return travel time of the user on the basis of geolocation data; (d) determining a return temperature on the basis of a comfort temperature, different from the living temperature, and on the basis of the return travel time, the return temperature allowing said system to reach the comfort temperature during the return travel time; and (e) sending, to said system, a return instruction whereby said system adjusts to the return temperature.
