Further, when the numerical value of the reference value is increased / decreased in this way, it is not preferable to increase / decrease the numerical value indefinitely. Therefore, the reference value changing program 7e is configured to advise the recommended upper limit value of the reference value. Yes.
As shown in FIG. 14, the recommended upper limit value is divided into three types of “maximum power”, “intermediate power”, and “minimum power”. Or one can be selected.
The “maximum power” is set based on the maximum value among the daily maximum values of power consumption for the past seven days, for example.

The “intermediate power” is set based on an intermediate value between “maximum power” and “minimum power”.

In addition, as described above, the reference value may be set based on a standard energy consumption amount for each of a plurality of branch circuits in a household having substantially the same scale. At this time, the reference value is determined based on the standard value data 8d. Further, since the standard value data 8d is classified by a plurality of areas, the standard value is determined based on the standard value data 8d of the area where the building is built.

A procedure for performing energy saving advice by the energy saving advice device 1 will be described.
FIG. 5 is a flowchart showing a flow of processing of energy saving advice by the energy saving advice device 1 according to the present invention.

First, the power measuring means 37 (FIG. 2) mounted on the distribution board 20, the pulse counter 38a (FIG. 3) provided between the energy saving advice device 1 and the gas meter 38, the energy saving advice device 1 and the flow rate. The energy consumption is measured for each branch circuit 21 to 36 by a pulse counter 39a (FIG. 4) provided between the sensors 39, and the data is stored as past data to the data storage unit 8 of the storage means 6. Accumulate (step S1).
Measurement of energy consumption and data accumulation for each branch circuit 21 to 36 are always performed.

  Subsequently, the comparison / determination means compares the energy consumption for each of the plurality of branch circuits 21 to 36 with the reference value of the energy consumption set for each of the plurality of branch circuits 21 to 36 (step S2). ).

Subsequently, the comparison determination unit determines whether or not the energy consumption of the plurality of branch circuits 21 to 36 compared with the reference value in step S2 is larger than the reference value (step S3). .
Here, for the branch circuit for which the energy consumption is determined to be larger than the reference value, the process proceeds to the next step S4, where it is determined that the energy consumption is substantially the same as the reference value and less than the reference value. For the branch circuit, the energy saving advice is not performed, and the process ends.

  In step S4, on the advice mode selection screen as shown in FIG. 11, “consumption reduction mode”, “consumption increase suppression mode”, “cost reduction mode”, “cost reduction mode by use time zone”, “general advice” The resident selects an arbitrary advice mode from a plurality of advice modes of “mode”.

Subsequently, as shown in FIG. 13, an energy saving advice display screen corresponding to the advice mode selected in step S4 is displayed, and optimum energy saving advice is given to the resident (step S5). For example, the energy saving advice in the “consumption reduction mode” is the order of the branch circuits having the energy consumption from the branch circuit having the largest energy consumption among the branch circuits 21 to 36 that are determined to consume the energy more than the reference value. The advice for reducing the consumption is displayed on the display monitor 3.
The above flow is the basic flow of energy saving advice processing. However, since the selection of the advice mode in step S4 can be omitted as described above, there may be a direct transition from step S3 to step S5.

  According to the present embodiment, the energy consumption of each of the plurality of branch circuits 21 to 36 is compared with the reference value, and the branch circuits 21 to 36 that consume more energy than the reference value are determined. Comparison judging means, and advice means for giving energy saving advice in the order of the branch circuit with the largest energy consumption to the branch circuit among the branch circuits 21 to 36 judged as consuming energy excessively than the reference value; Therefore, it is possible to easily identify which branch circuit should be preferentially subjected to the energy-saving action. Thereby, the resident can easily and effectively save the energy only by performing the energy saving action according to the energy saving advice advised by the advice means. In addition, since only branch circuits that are determined to consume more energy than the reference value are subject to energy saving, even if the energy saving action is carried out according to the energy saving advice, the comfort of the resident's life is impaired. This can be surely prevented.

  In addition, the energy consumed in the branch circuits 21 to 36 includes power used for devices connected to the branch circuits 21 to 36 and gas and water used in conjunction with the power.

  Further, the advice means is set not to give energy-saving advice to the branch circuits 21 to 36 whose energy consumption is determined to be substantially the same as the reference value and below the reference value. On the other hand, only branch circuits that consume excessive energy can be recognized as energy saving targets. As a result, energy can be saved more easily and effectively, and it is possible to more reliably prevent the resident's life comfort from being impaired.

  In addition, since the reference value is an average value of past energy consumption for each of the branch circuits 21 to 36, it is possible to set a reference value suitable for the life of the resident. This can more reliably prevent the resident's life comfort from being impaired.

Further, when the reference value is set based on the energy consumption of each of a plurality of standard branch circuits in a household of approximately the same scale, the degree of energy consumption of the plurality of branch circuits 21 to 36 is set as a standard. Can be determined by checking the value. As a result, the standard energy consumption for each of the branch circuits 21 to 36 can be known, and the residents can be encouraged to deepen their awareness of energy saving.
The standard energy consumption for each of the plurality of branch circuits is determined for each area where the building is constructed. As a result, it is possible to set a reference value suitable for the living environment of the area where the building is built, so that the occupant's life comfort is impaired while encouraging residents to deepen their energy conservation awareness. This can be prevented more reliably.

  Moreover, since the reference value changing means for changing the numerical value of the reference value is provided, the numerical value of the reference value can be arbitrarily changed by the resident so that the reference value is suitable for the resident's life. This can more reliably prevent the resident's life comfort from being impaired.

  Further, the advice means is set to advise the recommended upper limit value of the reference value when the reference value changing means changes the numerical value of the reference value. Therefore, it is possible to call attention so as not to become too high, and it is possible to surely prevent a reduction in energy saving effect.

  Moreover, since the display means for displaying at least the current energy consumption of the plurality of branch circuits 21 to 36 and the reference value of the energy consumption for each of the branch circuits 21 to 36 is provided, the plurality of branch circuits 21. The current energy consumption of .about.36 and the reference value for each of the branch circuits 21 to 36 can be reliably recognized and easily compared.

  In addition, the display means is set to display a warning when the comparison / determination means determines the branch circuits 21 to 36 that consume more energy than the reference value. Since the displayed information can be recognized with certainty, energy saving action can be implemented promptly.
