A method for separately detecting amounts of utility consumption by respective devices, the method comprising: generating first flow rate data by checking a flow rate of first-type water supplied through a first supply pipe; generating electric power amount data by checking electric power suppliec through an electric power lead-in wire; and via analysis of the first flow rate data and the electric power amount data, identifying a time interval in which a use pattern for the first-type water by a first device and a use pattern for the electric power by the first device are concurrently detected (S 604, S 606), and extracting, in the time interval, an amount of consumption of the first-type water and an amount of consumption of the electric power by the first device, wherein when the electric power use pattern by the first device is detected in the electric power amount data, but the water use pattern for the first-type water by the first device is not detected in the first flow rate data, it is determined that the first device is not operated in said time interval, and it is analyzed whether another device has consumed electric power in said time interval, wherein the method further comprises separately detecting (S 600) a base load, which represents constant consumption of electric power in a first range, in the electric power amount data, said method being characterized by: separately detecting a periodic load, which represents periodic consumption of electric power in a second range, in the electric power amount data from which the base load has been removed, wherein the extracting of the amount of consumption of the first-type water and the amount of consumption of the electric power by the first device comprises extracting the amount of consumption of the first-type water and the amount of consumption of the electric power via analysis of the electric power amount data from which the base load and the periodic load have been removed (S 602). generating first flow rate data by checking a flow rate of first-type water supplied through a first supply pipe; generating electric power amount data by checking electric power suppliec through an electric power lead-in wire; and via analysis of the first flow rate data and the electric power amount data, identifying a time interval in which a use pattern for the first-type water by a first device and a use pattern for the electric power by the first device are concurrently detected (S 604, S 606), and extracting, in the time interval, an amount of consumption of the first-type water and an amount of consumption of the electric power by the first device, wherein when the electric power use pattern by the first device is detected in the electric power amount data, but the water use pattern for the first-type water by the first device is not detected in the first flow rate data, it is determined that the first device is not operated in said time interval, and it is analyzed whether another device has consumed electric power in said time interval, wherein the method further comprises separately detecting (S 600) a base load, which represents constant consumption of electric power in a first range, in the electric power amount data, said method being characterized by: separately detecting a periodic load, which represents periodic consumption of electric power in a second range, in the electric power amount data from which the base load has been removed, wherein the extracting of the amount of consumption of the first-type water and the amount of consumption of the electric power by the first device comprises extracting the amount of consumption of the first-type water and the amount of consumption of the electric power via analysis of the electric power amount data from which the base load and the periodic load have been removed (S 602). separately detecting a periodic load, which represents periodic consumption of electric power in a second range, in the electric power amount data from which the base load has been removed, wherein the extracting of the amount of consumption of the first-type water and the amount of consumption of the electric power by the first device comprises extracting the amount of consumption of the first-type water and the amount of consumption of the electric power via analysis of the electric power amount data from which the base load and the periodic load have been removed (S 602).
