PROBLEM TO BE SOLVED: To provide an energy management system for visualizing and presenting power consumption inside a house and providing information useful for executing an effective energy saving action.SOLUTION: A home server includes: a measurement data acquisition part for acquiring measurement data of a main sensor for measuring the power consumption inside a house; an event notice data acquisition part for acquiring event notice data indicating the occurrence time of an event in which the operation state of a power consuming device is changed and contents of the event; a storage part for storing the measurement data and the event notice data; and a data transmission part for reading the measurement data and the vent notice data from the storage part and transmitting them to an information terminal 30. The information terminal 30 simultaneously displays both of a load variation graph indicating temporal change of measurement results of the main sensor and event information indicating the contents of the event on the basis of the data from the data transmission part, while associating the event information with a part corresponding to the occurrence time of the event on the load variation graph. |
