Alternatively, when the energy usage amounts are arranged in ascending order, the energy usage amount of the rank corresponding to the rank number of, for example, 5% from the smallest is used as the reference usage amount. Here, the rank number of 5% from the smallest means the rank number corresponding to 5% of the total number of customers when the customers included in the attributes are arranged in the order of small usage. For example, if the number of customers included in the attribute is 200, the tenth smallest usage amount is set as the reference amount. The set standard usage is

The amount of energy used may be measured by a measuring instrument. For example, as shown in FIG.
When the measuring device 26 that measures the energy usage amount and transmits the measured energy usage amount and the attribute to the management server 10 is installed in the customer's house, the energy usage amount and the attribute measured by the measuring device 26 are used as the management server. Sent to 10. Generally, the energy usage amount accumulated in one month is transmitted.

The energy consumption may be measured by a meter reader. For example, as shown in FIG. 2B, the meter reader or the like inputs the energy consumption, and the energy consumption and the attribute input. When using the mobile terminal 28 for transmitting to the management server 10, the energy usage amount and the attribute input to the mobile terminal 28 are transmitted to the management server 10.
Generally, the energy usage amount accumulated in one month is transmitted.

It can also be stored in the hard disk 13 of 0. Customers can be classified according to attributes.

Measuring instrument 26 shown in FIGS. 2 (a) and 2 (b)
And the energy usage of each attribute is sent from the mobile terminal 28 to the management server 10, and the management server 10 receives the energy usage of each attribute. Specifically, the communication device 15 receives the energy usage amount and the attribute sent from the measuring instrument 26 or the mobile terminal 28, and stores the energy usage amount and attribute in the hard disk 13.

Measuring instrument 26 shown in FIG. 2 (a) or (b)
Alternatively, when the energy usage amount is sent to the management server 10 by the mobile terminal 28, it is not necessary to input the energy usage amount used for the diagnosis, and for example, the CPU 11 uses the energy corresponding to the identification number included in the accepted attribute. It is possible to read the used amount from the hard disk 13 for diagnosis. When the energy usage amount is not stored in the management server 10, the energy usage amount is input and transmitted from the input unit 32 of the customer terminal 30.

Next, the evaluation of the energy consumption reduction degree using the energy consumption reduction evaluation system according to the present invention will be described.

FIG. 3 shows an example of a procedure for setting a reference usage amount (hereinafter referred to as a reference amount). The input unit 32 of the customer terminal 30,
The portable terminal 28 or the measuring device 26 is used to input or measure the energy usage (hereinafter referred to as usage) (S1).
0). The control unit 40 of the customer terminal 30, the mobile terminal 28, or the measuring instrument 26 transmits the input or measured usage amount and the attributes stored in advance to the management server 10 (S1).
2). The attributes are the storage unit 36 of the customer terminal 30, the mobile terminal 2
8 or in the memory (not shown) of the measuring instrument 26 in advance.

The communication means 15 of the management server 10 receives the used amount and attributes transmitted (S14). The received usage amount is stored in the hard disk 13 by the CPU 11 (S16). The attribute includes, for example, an identification number for each customer, and the usage amount is stored for each customer. The usage amount sent from a large number of customers not shown in FIG. 1 and FIGS.
3 is stored.

The CPU 11 sets a reference amount (reference usage amount) for each attribute (S18). For example, it is possible to classify the usage amount according to the attribute, obtain the minimum usage amount for each attribute, and set the minimum usage amount as the reference amount. As will be described later, the reference amount can be used as a target value for reducing the energy usage amount. In this case, the minimum amount actually consumed is the target value.

Alternatively, the usage amount close to the minimum value can be set as the reference amount. For example, it is possible to set the usage amount of the rank number of 5% from the smallest as the reference amount. The minimum usage may be a unique value, such as when you were out of the office on a trip, etc., so select a usage of 5% rank from the smallest value Can be excluded.

The set reference amount (reference usage amount) is the CPU
11 is stored in the hard disk 13 (S2
0). The reference amount can be set on a monthly basis, for example, in accordance with the measurement of the used amount. The reference amount is stored in the hard disk 13 on a monthly basis like the usage amount.

The reference amount can be a target value for reducing the used amount. An example of the display procedure of the target value is shown in FIG. The input unit 32 of the customer terminal 30 is operated to send a transmission request for the attributes and target values stored in advance in the storage unit 36 to the management server 10 (S42).

The management server 10 receives the transmission request of the attribute and the target value by the communication means 15 (S44).
The CPU 11 detects the reception of the target value transmission request, reads the reference amount (reference usage amount) corresponding to the received attribute from the hard disk 13 (S46), and transmits it from the communication means 15 (S48).

The transmitted reference amount is received by the communication unit 38 of the customer terminal 30 (S50). The received reference amount is sent to the output unit 34 and displayed by the control unit 40 (S
52). The customer works on energy saving by using the reference amount displayed on the output unit 34 of the customer terminal 30 as a target value.

Next, FIG. 5 shows an example of the procedure for evaluating the degree of reduction of the usage amount. In this description, a case where the usage amount is not stored in the management server 10 will be described as an example. The evaluation applicant operates the input unit 32 of the customer terminal 30 to input the usage amount (S60). After inputting the usage amount, the control unit 40 transmits the usage amount and the attributes stored in the storage unit 36 to the management server 10 (S62).

The used amount and attributes transmitted are the management server 1
It is received by the communication means 15 of 0 (S64). CPU11
Thus, the received usage amount and attribute are stored in the RAM 14, and the reference amount (reference usage amount) corresponding to the received attribute is read from the hard disk 13 to the RAM 14 (S6).
6). The CPU 11 makes an evaluation based on the received usage amount and the read reference amount (S68). In the evaluation,
The reduction amount of the received usage amount from the previous year is compared with the difference between the usage amount of the previous year and the read reference amount.

FIG. 6 shows an example of comparison between the reduction amount and the difference.
In FIG. 6, M1 and M2 are the same month of the previous year and this year, E1 is the amount used in the previous year, E2 is the amount used this year, and E3 is the reference amount set based on the amount used in the previous year. Is. Further, A (= E1-E2) is the reduction amount of the used amount from the previous year, and C = (E1-E3) is the difference between the used amount of the previous year and the reference amount.

The CPU 11 obtains A, C, and A / C, and makes an evaluation based on the obtained ratio. The larger the ratio, the higher the rating. For example, the ratio is a negative number (when the usage amount increases)
0 to 0.20, 0.21 to 0.40, 0.41
.About.0.60, 0.61 to 0.80, 0.81 to 1 ..
The evaluation can be performed in seven stages of 00 and 1.01 or more. The evaluation result is transmitted from the management server 10 to the customer terminal 30 (S70).

The transmitted evaluation result is received by the communication unit 38 of the customer terminal 30 (S72), sent to the output unit 34 by the control unit 40, and the evaluation result is displayed (S74). By being evaluated for energy saving efforts, customers can increase their motivation for energy saving efforts in the future. For example, ranking can be performed according to the calculated ratio. Since the ratio is calculated based on the reference amount according to the attribute, the ranking can be performed for each attribute or for all attributes.

In the above-mentioned embodiment, the reference amount is set to the used amount of the rank number of 5% from the smallest, but the reference amount is 5%.
It is not limited to%, but can be set to, for example, 10%. Alternatively, the average value of the usage amount of customers classified into the same attribute can be set as the reference amount.

For example, the average value of the used amount is set as the first reference amount, the used amount of the rank number of 5% from the smallest is set as the second reference amount, and the used amount of the evaluation object is set to be lower than the first reference amount. When it is larger, the first reference amount can be set to the target value, and when it is smaller than the first reference amount, the second reference amount can be set to the target value. If the usage amount greatly exceeds the average value, the difference with the reference amount that is close to the minimum (ranking 5% from the smallest) is large, making it an unrealistic target, and willingness to work on energy saving May disappear. However, when the reference amount close to the average value is set, it becomes a realistic target, and the motivation for energy saving can be increased.

Further, in FIG. 6, the start of the period (M
The ratio (A / C) was calculated using the reference amount E3 of 1),
As shown in FIG. 7, the ratio (A / D) can be calculated using the reference amount E4 at the end of the period (M2). The reference amount fluctuates year by year even in the same month, and in FIG. 7, the current reference amount can be used for evaluation.

It is also possible to transmit the amount of electricity used from the measuring device 26 and the amount of water and gas used from the customer terminal 30, for example. In this case, electricity, gas, and water can be evaluated separately, or electricity, gas, and water can be collectively evaluated.

Further, in FIG. 1, the reception of the usage amount and the attribute, the setting of the reference amount, and the evaluation of the reduction degree are performed by one device (management server 10). The reception and the setting of the reference amount may be performed by another device, and the reference amount according to the attribute may be acquired from the other device.
Alternatively, the customer terminal 30 can evaluate the reduction by receiving the reference amount according to the attribute from the management server 10.
In this case, only the attributes are sent from the customer terminal 30 to the management server 10.
