The data in the second and third rows has an ON / OFF difference in the operation state of the microwave oven, and the operation states of other devices are all the same.

(S602)
The power consumption estimation unit 114 calculates the power consumption value of the electric device 201 from the difference between the instantaneous power consumption values in the data extracted in step S601.
For example, in the example of FIG. 5, it can be estimated that the power consumption value of the air conditioner is 400 W from the difference between the instantaneous power values of the first and second pairs. Similarly, it can be estimated that the power consumption value of the microwave oven is 300 W from the difference between the instantaneous power values of the second and third pairs.

The target data acquisition unit 115 extracts data related to the operating status of the electrical device system 200 that is the target of energy saving support from the usage status storage unit 113.
In this step, for example, a method may be used in which the electric device system 200 that is the target of energy saving support is identified from the user ID obtained in the authentication process in step S702 and the operating status of the electric device 201 in the current month is extracted. it can.

(S704)
The comparison data acquisition unit 116 extracts operation status data to be compared with the operation status data of the electrical device system 200 that is the target of energy saving support from the usage status storage unit 113. If the extraction condition is not particularly specified, all operation status data may be extracted.

(S705)
The aggregation unit 117 aggregates the data extracted by the target data acquisition unit 115 and the data extracted by the comparison data acquisition unit 116, and creates response data to be transmitted to the user. FIG. 8 described later shows an example of response data.

(S706)
The communication unit 112 transmits the response data created by the totaling unit 117 as an HTTP response to the HTTP client that has accessed the energy saving support apparatus 100 in step S701.

  FIG. 8 is a diagram illustrating an example of response data. Here, an example is shown in which the operation status for each electrical device 201 is tabulated in a suitable period and represented by a bar graph. The bar graph on the left represents the average value of the electric device system 200 that is the target of energy saving support, and the bar graph on the right represents the average value of the electric device system 200 selected as the comparison target.

The vertical axis of the aggregated data may be the operating time of the electric device 201, or a value (power consumption) obtained by multiplying the estimated power consumption value of each electric device 201 calculated by the power consumption estimating unit 114 by the operating time. There may be.
The operating time of the electrical device 201 can be calculated based on the operating status of each electrical device 201 collected from the electrical device system 200. For example, a value obtained by multiplying the number of times the operating status is stored as ON in the usage status storage unit 113 by the time interval for storing data (1 hour in the example of FIG. 5) may be estimated as the operating time.

As described above, in the first embodiment, the power consumption estimation unit 114 calculates the power consumption of each electric appliance 201 operating in the electric appliance system 200 based on the operating status of the electric appliance 201 transmitted by the electric appliance system 200. presume.
