In energy conservation, it is important for users on the consumer side to take energy conservation actions to reduce power consumption over a long period of time. In order for users to continuously take energy-saving behavior, it is a problem that the user keeps motivation without getting tired of energy-saving measures.
The present invention has been made in view of the above-described circumstances, and has an object to provide an energy saving support system and an energy saving support program that can maintain an eagerness for energy saving measures and continuously take energy saving actions. To do.

In order to achieve the above object, the present invention provides a measuring means for measuring the power consumption of a consumer having a plurality of load devices, and receives the measured value of the power usage from the measuring means via a telecommunication line. A server computer provided with communication means for performing communication, and a customer terminal connected to the server computer via the electric communication line so as to be communicable and outputting information received from the server computer, and the server computer is the energy saving action plan that defines the handling of the load device for obtaining energy savings, and the action plan storage means for storing for each of the load device, based on the power consumption over a predetermined period, the customer The horizontal axis of the load duration curve represents the peak range including the peak power usage, the power It is divided into a base range in which the usage amount is maintained constant, and a normal range between the peak range and the base range, and the total amount of power usage in each range occupies the total amount of power usage in the predetermined period Based on the ratio, the excessive power usage range is identified from the range, and each load device that is pre-classified as a device that contributes to the total amount of power usage in the range is used. It is regularly identified that the device is expected to reduce the amount, selects the energy saving action plan associated with each load device from the action plan storage means, and transmits it to the consumer side terminal via the communication means An energy saving support system characterized by comprising an action plan providing means for performing automatically.

According to the present invention, the measurement of the power usage amount of the consumer and the transmission of the energy saving action plan according to the measurement result to the consumer side terminal are periodically executed. As a result, energy conservation action plans are reviewed regularly according to the power usage status of consumers, and users are always provided with fresh energy conservation action plans that match the power usage status. Without being bored, and can continue to take energy-saving actions.
Furthermore, according to this invention, the energy-saving action plan which prescribed | regulated the handling of the load apparatus with which reduction of power consumption is anticipated among the load apparatuses with which a consumer is equipped is transmitted to a consumer side terminal as an energy-saving action plan.
As a result, the user can easily know which load equipment should be handled in order to save energy, without making it difficult to take energy saving action, Can be motivated to perform.

  Further, the present invention provides the energy saving support system, wherein the server computer inquires of the customer terminal whether or not the action prescribed in the energy saving action plan has been performed, obtains a user's answer, and the result of the answer Based on evaluation of the implementation status of the energy saving action plan, and the implementation status evaluation means for periodically transmitting the result of the evaluation to the consumer side terminal via the telecommunication line, To do.

  ADVANTAGE OF THE INVENTION According to this invention, the implementation state confirmation of an energy-saving action plan and the evaluation of an implementation condition are regularly performed with respect to a user, and the fall of the user's motivation with respect to an energy-saving action can be prevented.

  In the energy saving support system according to the present invention, the server computer includes a proposed action plan storage unit that stores an energy saving action plan that has been transmitted to the customer side terminal, and the action plan providing unit includes the energy saving action unit. When the plan is transmitted to the customer side terminal, it is transmitted except for the transmitted energy saving action plan.

  According to the present invention, it is possible to prevent the energy saving action plan already proposed to the user from being proposed again, and to propose only a new action plan.

  According to the present invention, in the energy saving support system, the server computer evaluates an energy saving effect in the customer based on a change in the measured value of the power consumption, and the result of the evaluation is used as the customer side terminal. And an energy saving effect evaluating means for periodically performing transmission through the telecommunication line.

  According to the present invention, since the evaluation of the energy saving effect at the consumer and the transmission of the result of the evaluation are periodically performed, it is possible to prevent the user's willingness to save energy.

Further, the present invention is the above energy saving support system, wherein the energy saving effect evaluation means of the server computer is based on the measured value of the power consumption received from each of the measuring means of the consumers to be evaluated for the energy saving effect , evaluate the energy savings due to the entire customer, and transmits via the telecommunications line to said customer-side terminal of each consumer.

The energy saving measures are performed independently for each customer, but since the amount of individual energy savings is relatively small, there is a possibility that the user's willingness to save energy may decrease.
According to the present invention, since the energy saving effect of the entire consumer is an evaluation target, the amount of energy saving becomes relatively large, and the evaluation result is provided to the user of each consumer. Thereby, it becomes possible for the user of each consumer to recognize the evaluation with respect to the energy amount reduced as a whole consumer as a social contribution, and the motivation for an energy saving action is heightened.

The present invention, in the energy saving support system, wherein the server computer, the load device which the customer is provided, before Symbol the peak range first device contributes to the total power consumption of the load duration curve, said base range Provided with consumer-owned equipment storage means for classifying and storing each of the second equipment that contributes to the total amount of power consumption and the third equipment that contributes to the total amount of power usage in the normal range , and provides the action plan The means reads out the load device classified into the range in which the power usage amount is specified as being excessive from the consumer-owned device storage unit, and identifies the load device in which the power usage amount is expected to be reduced. To do.

  According to the present invention, a load device having a relatively excessive amount of power usage among load devices included in the consumer is identified based on a measured value of the total power usage of the consumer. For this reason, since it is not necessary to measure the electric power consumption of each load apparatus separately, the number of meters required for the electric power consumption measurement can be suppressed, and the installation property can be improved and the cost can be reduced.

  Further, the present invention provides the energy saving support system, wherein the customer-owned device storage means classifies the load device of which the use time is specified among the load devices included in the consumer as the seasonal home appliance, and the seasonal home appliance. The load devices that do not correspond are classified and stored as the first to third devices, and the action plan providing means identifies the seasonal home appliances used by the consumer based on the use time of each seasonal home appliance, An energy saving action plan associated with a seasonal home appliance is selected from the action plan storage means and transmitted to the consumer side terminal via the communication means.

According to the present invention, a load device whose use time is specified is classified as a seasonal home appliance, and a load device that does not correspond to a seasonal home appliance is classified as a first to a third device. Distinguished. Seasonal home appliances can reliably determine whether or not they are used by consumers based on the time of use, so they can more reliably identify only the load devices used by consumers and provide energy conservation action plans for those load devices. be able to.
In addition, it is desirable to periodically provide an energy saving action plan for a seasonal home appliance during a period in which the seasonal home appliance is used. Thereby, since the energy saving action plan is periodically provided for seasonal home appliances that use a relatively large amount of power, the energy saving effect is enhanced.

Furthermore, seasonal household appliances include air-conditioning equipment such as air conditioners that consume a large amount of power during operation and consume standby power. In other words, during the period when air conditioning equipment is used, the curve shape of the load duration curve varies greatly depending on the power usage of the air conditioning equipment, affecting the overall peak power, base power, and normal power consumption. Therefore, it is difficult to determine the excessive power consumption of the first to third devices from the shape of the load duration curve, and it becomes difficult to provide an appropriate energy saving action plan.
On the other hand, in the present invention, such an air conditioner is preferentially distinguished as a seasonal home appliance, and the presence or absence of use of the seasonal home appliance is determined depending on the time of use. Energy conservation action plan can be provided. Moreover, it is estimated that the load duration curve obtained after provision of the energy saving action plan is a result of using the air-conditioning apparatus based on the energy saving action plan. That is, from the curve shape of the load duration curve, it is possible to determine an excessive amount of power usage of the first to third devices without considering the influence of seasonal home appliances, and appropriate energy saving for the load device of the consumer Proposed action plan.

  According to the present invention, in the energy saving support system, the server computer includes an advertisement information storage unit that stores advertisement information of a product serving as a substitute for the load device, and the action plan providing unit reduces power consumption. The advertisement information corresponding to the expected load device is read from the advertisement information storage means and transmitted to the consumer side terminal via the telecommunication line.

  ADVANTAGE OF THE INVENTION According to this invention, the advertisement information which urges | urges replacement of the load apparatus with respect to the load apparatus with which reduction of electric power consumption is anticipated, ie, the load apparatus of energy saving action object, is provided to a user. As a result, replacement with a new product with less power consumption is promoted, and the energy saving effect is enhanced.

In order to achieve the above object, the present invention receives the measurement value of the power usage amount from a measuring unit that measures the power usage amount of a consumer having a plurality of load devices, via the telecommunication line, and An action plan storage that stores, for each load device, an energy saving action plan that prescribes the handling of the load device for obtaining an energy saving effect on a server computer provided with communication means for transmitting information to a consumer side terminal of the customer Means for obtaining a load duration curve of the power usage amount at the consumer based on the power usage amount over a predetermined period, the horizontal axis of the load duration curve being a peak range including the peak power usage amount, power It is divided into a base range in which the usage amount is maintained constant, and a normal range between the peak range and the base range, and the total amount of power usage in each range is the predetermined period. Each of the load devices that are pre-classified as devices that contribute to the total amount of power usage in the range, specifying a range where the power usage is excessive from the range based on the proportion of the total amount of power usage Is selected as a device that is expected to reduce the amount of power used in the range, and an energy saving action plan associated with each load device is selected from the action plan storage unit, and the communication unit is connected to the consumer side terminal. An energy-saving support program is provided, which functions as an action plan providing unit that periodically performs transmission via the network.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram schematically illustrating a configuration of an energy saving support system 1 according to the present embodiment. The energy saving support system 1 supports energy saving measures by providing action plans linked to energy saving to a large number of consumers 2 who use electric power.
As shown in FIG. 1, the energy saving support system 1 enables a power measurement system (measuring means) 4 installed in each consumer 2 and the power measurement system 4 to communicate via an electric communication line 6. A communication device 7, an energy saving support server computer (hereinafter abbreviated as “support server”) 8 to which the power measurement system 4 is communicably connected, and information received from the support server 8 provided in the consumer 2 A customer-side terminal 9 for output is provided.
The consumer 2 corresponds to, for example, a general household or business office, and a large number of electrical appliances such as a refrigerator, a television, a washing machine, and an air conditioner are provided as the load device 10. Electric power is supplied to these load devices 10 from a distribution board 12 installed in the consumer 2.

The power measurement system 4 measures the amount of power used by the customer 2 and includes an overall measuring instrument 14 and a receiver 16.
The overall measuring instrument 14 is wirelessly connected between the receiver 16 and a current detector that detects current flowing from the distribution board 12 to each outlet (not shown) and detects power used by the entire consumer. A wireless communication device that communicates, and wirelessly transmits the detection value of the current detector to the receiver 16 using the wireless communication device.
The power measurement system 4 further includes an individual measuring instrument 20. The individual measuring device 20 is distinguished from the load device 10 provided in the consumer 2 by a device such as a refrigerator (hereinafter referred to as a constantly operated device, which is normally operated in a normal usage mode, with reference numeral 10A). ), And the amount of power consumed by the constantly operating device 10A is detected. The individual measuring device 20 is a wireless communication device that wirelessly communicates between the receiver 16 and a current detector that detects a current flowing through the constantly operating device 10A and detects the amount of power used in the constantly operating device 10A. The detected value of the current detector is wirelessly transmitted to the receiver 16 using a wireless communication device.
As a result, the amount of power used by the constantly operating device 10 </ b> A is detected separately from the total amount of power used by the entire consumer 2.
The receiver 16 receives the detection values from the total measuring instrument 14 and the individual measuring instrument 20 and outputs them to the communication device 7 for transmission to the support server 8.
For communication between the receiver 16, the overall measuring instrument 14, and the individual measuring instrument 20, a comparatively short-range wireless communication standard such as Bluetooth (registered trademark) or a wireless LAN is preferably used.

In addition to the refrigerator, the above-described always-on device 10A includes, for example, a communication device such as a router device or an integrated device (so-called hub), a computer installed in the customer 2, and the like. The individual measuring device 20 may not be provided in all of these always-on devices 10A, but may be provided only in devices that use a relatively large amount of power, such as a refrigerator or a computer.
The determination as to whether or not the amount of power used by the always-on device 10A is large is determined based on the ratio of the amount of power used by the always-on device 10A to the amount of regular power (described below, for example, exceeding 10%) The That is, when the energy saving effect is expected by separately defining the handling method of the constantly operating device 10A from the other load devices 10, the individual measuring device 20 is provided in the always operating device 10A.

The communication device 7 communicates bidirectionally between the support servers 8 via an electric communication line 6 such as the Internet. Specifically, the communication device 7 acquires the power usage amount from the receiver 16 at predetermined measurement intervals (for example, 1 minute or 30 seconds), and transmits the power usage amount information to the support server 8. The power usage information includes a customer ID for uniquely identifying the customer 2, a measurement time (including date), the total power usage of the customer 2, and a constantly operating device provided in the customer 2. An individual power consumption of 10A is included.
The communication device 7 receives various information from the support server 8 and outputs the information to the customer side terminal 9.

The customer side terminal 9 outputs the information transmitted from the support server 8 to present it to the user on the customer 2 side, accepts information input from the user, and communicates the input information to the support server 8. Transmit using device 7. Specifically, for example, a video phone or the like including a display unit 22 that displays various information and an operation input unit 24 that receives a user's operation input is preferably used as the customer side terminal 9.
In addition, data transmission / reception between the customer side terminal 9 and the support server 8 is configured so that the support server 8 has an HTTP server function and can provide a WEB service. This is done by the customer side terminal 9 accessing the site. Of course, data transmission / reception between the customer terminal 9 and the support server 8 may be performed using a communication protocol other than HTTP (for example, SMTP or the like).

FIG. 2 is a block diagram showing a functional configuration of the support server 8.
As shown in the figure, the support server 8 includes a communication unit 30, a database unit 32, an action plan providing unit 34, an implementation status evaluation unit 36, and an energy saving effect evaluation unit 38. .
The support server 8 is configured using a general computer system that includes a CPU as a control means, a ROM, a RAM, a hard disk drive as a program storage means, and the like (all not shown). The energy saving support program is installed in the hard disk drive by causing the computer system to read the energy saving support program according to the present invention recorded on a recording medium such as a CD-ROM. And various functions shown in Drawing 2 are realized because a computer program runs the energy saving support program concerned. Further, as described above, the support server 8 has an HTTP server function and is configured to be able to provide a WEB service to the customer side terminal 9.

Explaining each part of the support server 8, the communication part 30 performs bidirectional data communication with the communication device 7 installed in each customer 2 via the telecommunication line 6.
The database unit 32 stores various types of information, and includes a customer information database 40, an action plan database 44, a suggested action plan database 45, an evaluation result database 46, and an advertisement information database 47. .
The customer information database 40 stores customer information 42 that is information for managing each customer 2.

FIG. 3 is a diagram schematically illustrating an example of the contents of the customer information 42.
As shown in the figure, the customer information 42 includes ID 42A, family / home attribute information 42B, behavior information 42C, and home appliance information 42D as identification information of the customer 2.
The family / family attribute information 42B includes information such as the family structure (number of employees in the office, etc.) such as the number of family members, and the structure and size of the building. Based on the family structure and the structure of the building, the approximate power demand at the customer 2 can be estimated. Moreover, it becomes possible to calculate by normalizing the electric power consumption, such as the electric power consumption per person or the electric power consumption per unit area. It is possible to compare the power consumption.

  The behavior information 42 </ b> C is information for knowing a time zone in which a lot of electric power is used or not used in the day depending on the user's daily behavior. The behavior information 42C includes, for example, a bedtime and a wake-up time for specifying a user activity / inactivity time period, a breakfast end time for specifying a meal time period, a lunch end time and a dinner end time, an air conditioner, and the like. The start and end times of cooling and the start and end times of heating for specifying the use time of seasonal home appliances are included.

The home appliance information 42D manages the load device information of the load device 10 included in the consumer 2. This load device information includes the device name of the load device 10 and the continuous curve contribution classification.
As the device name, for example, general article names of the load device 10 such as “air conditioner”, “electric carpet”, “electric kotatsu”, “refrigerator”, “vacuum cleaner”, etc. are used. In addition to the device name, for example, the manufacturer name, product model number, and product manufacturing date may be managed.
The sustained curve contribution classification indicates a classification classified in terms of the influence of the power usage amount by the load device 10 on a load duration curve described later obtained from the total power usage amount of the customer 2. Although details of this classification will be described later, in the present embodiment, the load device 10 is classified into one of “first device”, “second device”, “third device”, and “seasonal home appliance”. The
Only the “seasonal home appliance” has a different viewpoint from other “first device” to “third device”, and the load device 10 is generally used in the summer, winter, or summer. In the case of seasonal household appliances that are limited to periods other than the winter season (hereinafter referred to as “intermediate period”), the category is defined as the “seasonal household appliance” regardless of the influence of the load device 10 on the load duration curve. The
Examples of the load device 10 classified as “seasonal home appliance” include an air conditioner, an electric carpet, an electric kotatsu, a dehumidifier, and a humidifier.
Of the load devices 10, devices that are not classified as “seasonal home appliances” are classified into “first device”, “second device”, and “third device”.

The action plan database 44 stores a number of energy saving action plans to be proposed to the user of the customer 2 for each load device 10.
In a broad sense, energy saving behavior means the overall user behavior that leads to an energy saving effect. In the present embodiment, among such user actions, in particular, the usage of the load device 10 that leads to an energy saving effect is defined as an energy saving action. A specific example of the energy saving action will be described with reference to FIG.

FIG. 4 is a diagram schematically showing the action plan database 44.
As shown in the figure, one record of the action plan database 44 includes an action plan number, a device name, a plan provision time, an energy saving action plan, and an advice sentence that uniquely identify the energy saving action plan. Yes.
The device name is the device name of the load device 10 that is the target of the energy saving action specified in the energy saving action plan.
The plan provision time specifies the time when the energy saving action plan can be provided to the user.
More specifically, among the load devices 10, there are seasonal appliances such as heating devices and cooling devices whose use time is limited to summer, winter, or intermediate periods excluding summer and winter. It is desirable that such an energy saving action plan for seasonal home appliances is provided only at the time of use. Thus, the plan provision time is designated as a time when the energy saving action plan can be provided to the user depending on whether or not the load device 10 is a seasonal home appliance. In addition, when the load device 10 is not a seasonal home appliance, “year-round” to provide the user with the energy saving action plan regardless of the time is designated as the plan provision time.

As described above, the energy saving action plan is a proposal sentence that defines how to use the load device 10 that is linked to the energy saving effect, and the advice sentence is message data instructing specific action contents of the energy saving action plan.
More specifically, depending on the living environment of the user on the consumer 2 side, there may be a case where the energy saving action plan cannot be executed, for example, because the proposed load device 10 must be constantly operated. That is, rather than specifically suggesting all energy conservation action plans to the user at once, grasp the energy conservation action plans that can be executed by the user and provide specific action details only for the executable energy conservation action plans. Providing proposals in two stages, such as proposing, is easier for the user to use. In addition, energy saving efforts can be continued because the measures that can be implemented by the user are limited.
Therefore, in the present embodiment, when the energy saving support is performed, the user 2 of the customer 2 is first presented with the energy saving action plan, and the advice sentence is presented only for the user who answered that it can be executed. Is done.

A specific example of the energy saving action plan and the advice sentence will be described in the case where the load device 10 is a refrigerator. As energy saving measures for the refrigerator, “do not pack too much goods in the cabinet”, “do not open and close the door unnecessarily”, Examples include “shortening the door opening time” and “inserting hot items after cooling”.
Therefore, the energy saving action plan corresponding to the refrigerator includes the above-mentioned statements indicating the contents of the energy saving measures, that is, “Let's organize the refrigerator without stuffing too much”, “Let open and close only when putting in and out things”, “Door "Let's keep the time to open the window short", "Let hot items cool before putting them in the refrigerator."
In addition, as an advice sentence corresponding to the refrigerator, let's organize the sentence indicating the specific action content when executing each energy saving action plan, that is, “aiming about 50 to 80%. "Does it contain past food, food stored at room temperature?" Or "Do not open or close it except when it is not in use."

Returning to FIG. 2, the proposed action plan database 45 is for managing the energy saving action plan that has been proposed to the user of the customer 2, and the ID of the customer 2 and the proposed energy saving action plan. The action plan number and the implementation status indicating whether or not the user has executed each energy saving action plan are stored in association with each other.
The evaluation result database 46 stores, for each customer 2, the energy saving action plan that has been executed by the user on the customer 2 side and the reduction amount of the power consumption when compared with before the energy saving measures are taken. . By managing the energy saving action plan that has been executed by the user, it is possible to prevent the energy saving action plan that has already been executed from being proposed to the same user.

  The advertisement information database 47 stores advertisement information that is an advertisement for a replacement product of the load device 10 in association with each load device 10. The advertisement information further includes information indicating the degree of energy saving such as annual power consumption (electricity cost) and “achieving 40% energy saving compared to the old product”. By providing such information to the user, the user can grasp how much energy-saving effect can be expected by replacing the load device 10, and the motivation for replacement is increased.

The action plan providing unit 34 identifies the load device 10 that is expected to reduce the power usage based on the measurement result of the measurement value of the power usage of the customer 2 over a predetermined period, and associates the load device 10 with the load device 10. The selected energy saving action plan is selected from the action plan database 44 and periodically transmitted to the customer side terminal 9 via the communication unit 30.
More specifically, the action plan providing unit 34 includes a power usage amount totaling unit 50, a load duration curve calculating unit 52, a power consumption type determining unit 54, and an energy saving action plan selecting unit 56.

The power usage amount totaling unit 50 acquires power usage amount information from the customer 2 at regular intervals (for example, 1 minute or 30 seconds) via the communication unit 30, and the total power usage amount of the customer 2 and The individual power consumption of the constantly operating device 10 </ b> A included in the consumer 2 is accumulated. The power usage totaling unit 50 counts the total power usage for each predetermined period, and registers the current total power usage reduction rate in the evaluation result database 46 from the previous time.
Furthermore, the power usage totaling unit 50 totals the total power usage in an arbitrary totaling period such as every 30 minutes, and generates data for publishing the totaling result as, for example, a WEB page. When a user on the customer 2 side browses the totaled result published, he / she accesses and browses the web page of the totaled result from the customer side terminal 9.

FIG. 5 is a diagram illustrating a display example of the power usage amount totaling screen 58.
The power usage amount totaling screen 58 is displayed on the display unit 22 when the customer side terminal 9 accesses the WEB page of the totaling result. On this power usage totaling screen 58, the last update date 58A, the total power usage 58B measured immediately before, and the integrated value of power usage over a predetermined totaling period (for example, 30 minutes) are plotted. And a power usage graph 58 </ b> C that displays a change in power usage in a graph.
The user can grasp the power usage amount and its fluctuation in real time at an arbitrary timing by browsing the power usage amount totaling screen 58.

Returning to FIG. 2, the load duration curve calculation unit 52 uses the total power usage over a predetermined period (for example, 6 days or 27 days) based on the total power usage accumulated in the power usage totaling unit 50. The load duration curve is calculated from the amount and the individual power consumption.
FIG. 6 is a diagram schematically illustrating an example of a load duration curve.
The load duration curve is obtained by rearranging the total power usage per minute in a predetermined period in descending order of value.
In this embodiment, for each of the total power usage and the individual power usage, an average value between the measurement values at the same time (the same measurement value on each day) between different dates is calculated, and the average The load duration curve is calculated using the value. Thereby, for example, even when the lifestyle of the user on the customer 2 side changes for each day of the week or only on a predetermined day, a load duration curve for the average lifestyle of the user is obtained.

In this load duration curve, the area (integrated value) indicates the total amount of power consumption during a predetermined period. The peak range 53A, which is a range in which the power consumption is relatively large, indicates that among the load devices 10 provided in the consumer 2, a device having a relatively large maximum power such as a dryer or a microwave oven has been used by the user. The accumulated usage time of the load device 10 is indicated by the length of the range 53A.
The base range 53C, which is a range in which the amount of power used is relatively small and is maintained substantially constant, depends on the constantly operating device 10A among the load devices 10 included in the consumer 2 and devices that consume standby power. Power usage is shown.
Further, in a range (hereinafter referred to as “normal range”) 53B excluding the peak range 53A and the base range 53C, the use of power by the load device 10 such as a television or lighting having a relatively small maximum power is shown. .

The peak range 53A is, for example, an average power consumption of a device whose power consumption during use is extremely larger than that of a normal electrical appliance such as a television among the load devices 10, and exceeds the threshold value. Can be determined as a range.
Further, the duration of the base range 53C may be a range in which the power consumption is maintained substantially constant, or an inactivity time (sleep) determined from the bedtime and the wake-up time defined in the behavior information 42C of the customer information 42 Time).

The power consumption type determination unit 54 shown in FIG. 2 determines the power consumption type of the customer 2 based on the load duration curve.
As described above, the total amount of power in the peak range 53A (hereinafter referred to as “peak power amount”) is due to the use of the load device 10 with relatively large power consumption, and the peak power amount becomes excessive. In such a case, the use of the load device 10 cannot be prohibited, and the peak power amount can be reduced by shortening the use time of the load device 10.
The total amount of power in the base range 53C (hereinafter referred to as “base power amount”) is based on the amount of power used by the constantly operating device 10A and the standby power of the load device 10. In other words, when the base power amount is excessive, the usage is devised so that the power consumption of the always-operating device 10A can be provided, or the main power source of the load device 10 requiring standby power is frequently used. The base power amount can be reduced by cutting off (unplugging the power plug from the outlet) or the like so as not to consume standby power.
Further, the total amount of power in the normal range 53B (hereinafter referred to as “normal power amount”) is due to the use of a normal load device 10 that does not consume as much power as it belongs to the peak range. When the amount is excessive, it is possible to reduce the amount of common power by changing the usage so as to reduce the power consumption of the load device 10.

Based on the load duration curve, the power consumption type determination unit 54 identifies an excessive amount from among the peak power amount, the base power amount, and the normal power amount, and determines the power consumption type of the customer 2 as the peak power amount. It is classified into one of “peak power amount excessively large” with an excessive amount, “base electric energy excessively large” with an excessive base electric energy, and “ordinary electric energy excessively large” with an excessive ordinary electric energy.
Whether or not each power amount is excessive is determined by a ratio of the total amount of power used. In this embodiment,
If the total amount of peak power / power consumption> 20%, the peak power amount is excessive. If the total amount of base power / power consumption is> 15%, the base power amount is excessive. If the total amount is greater than 70%, it is determined that the normal power consumption is excessive.
In addition, the ratio used for this determination is an example to the last, and can be changed in the range which can determine a power consumption type.

The energy saving action plan selection unit 56 identifies the load device 10 to be subjected to the energy saving action based on the power consumption type of the customer 2, reads out the energy saving action plan corresponding to the load device 10 from the action plan database 44, Transmit to the home terminal 9.
More specifically, in this embodiment, the load device 10 includes a first device that affects the peak power amount, a second device that affects the base power amount, a third device that affects the normal power amount, a season, It is classified as one of home appliances.

The first device is a load device 10 with relatively large power consumption, such as a dryer, a microwave oven, an oven toaster, or the like. The second device is an always-on device 10A such as a refrigerator or a load device 10 that consumes standby power such as a television or a facsimile. The third device is a device that consumes electric power only during use, such as a lighting or a ventilation fan, and the power consumption is not as great as that of the first device. In addition, as described above, seasonal home appliances are devices that have a certain period of use within a year, such as air conditioners, electric kotatsu, electric heaters, and the like, electric fans, dehumidifiers, humidifiers, and the like. .
In the home appliance information 42D of the customer information 42, as shown in FIG. 3 above, the load device 10 includes the “first device” to the “third device” with respect to the load device 10 included in the customer 2. A continuous curve contribution classification indicating whether it belongs to “seasonal home appliances” is attached.

The energy saving action plan selection unit 56 identifies a category from “first device” to “third device” based on the determination result of the power consumption type of the customer 2 and loads the load device 10 associated with the category. The home appliance information 42D of the customer information 42 is selected.
Thereby, according to the power consumption type of the consumer 2, the load apparatus 10 which should take an energy saving action is specified appropriately. Then, the energy saving action plan selection unit 56 selects an energy saving action plan associated with the identified load device 10 from the action plan database 44.

  Furthermore, the energy-saving action plan selection unit 56, when there is a seasonal home appliance currently used in the load device 10 included in the consumer 2, the energy-saving action associated with the load device 10 that is the seasonal home appliance. A plan is also selected from the action plan database 44. As a result, an energy saving action plan is provided for seasonal home appliances that are likely to be used by the consumer 2, so an energy saving action plan that matches the power usage situation of the customer 2 is provided, and a high energy saving effect is provided. Be expected.

Seasonal home appliances also include air conditioners such as air conditioners that consume a large amount of power during operation and consume standby power. In other words, during the period when air conditioning equipment is used, the curve shape of the load duration curve varies greatly depending on the power usage of the air conditioning equipment, affecting the overall peak power, base power, and normal power consumption. Therefore, it is difficult to determine the excessive power consumption of the first to third devices from the shape of the load duration curve, and it becomes difficult to provide an appropriate energy saving action plan.
On the other hand, according to the present embodiment, since such air conditioning devices are preferentially distinguished as seasonal home appliances, the presence or absence of use of the seasonal home appliances is determined according to the time of use. It is possible to provide an appropriate energy conservation action plan. Moreover, it is estimated that the load duration curve obtained after provision of the energy saving action plan is a result of using the air-conditioning apparatus based on the energy saving action plan. That is, from the curve shape of the load duration curve, it is possible to determine an excessive amount of power usage of the first to third devices without considering the influence of seasonal home appliances, and appropriate energy saving for the load device of the consumer An action plan will be provided to the user.

Here, as described above, the base power amount is based on the amount of power used by the constantly operating device 10A and the standby power of the load device 10, so the load duration curve is the amount of power used by the constantly operating device 10A. It is calculated using a value obtained by subtracting the individual power consumption from the total power consumption.
As a result, when the power consumption type is excessively large in the base power amount, it is possible to estimate that the standby power is large, and by providing an energy saving action plan that reduces the standby power, the actual situation of the power consumption of the customer 2 Therefore, a more suitable energy conservation action plan is selected.
Of course, when the individual power consumption of the always-on device 10A is large, the energy conservation action adapted to the actual situation of the power consumption of the customer 2 is provided by providing an energy conservation action plan that reduces the individual power consumption. Can provide a draft.
Note that which of the load devices 10 is the constantly operating device 10A is, for example, a flag corresponding to the constantly operating device 10A for each load device 10 in the home appliance information 42D ("(always)" in FIG. 4). (Indicated by

The energy-saving action plan selection unit 56 transmits the energy-saving action plan selected based on the power consumption type and the energy-saving action plan selected based on the information on the seasonal home appliances to the customer side terminal 9, and the user on the customer 2 side Provide energy conservation action plans. Further, the energy saving action plan selection unit 56 registers the energy saving action plan provided to the user in the proposed action plan database 45.
The support server 8 generates the WEB page data of the energy saving action plan providing screen 60 for displaying the energy saving action plan, and the support server 8 responds to the access request to the WEB page from the customer side terminal 9. It is provided to the user on the customer 2 side by transmitting the WEB page.

FIG. 7 is a diagram illustrating an example of the energy saving action plan providing screen 60 displayed on the customer side terminal 9.
The energy saving action plan providing screen 60 displays a device to be subjected to the energy saving action and an energy saving action plan for the device, and further, an execution for the user to answer whether or not each energy saving action plan can be executed. A permission / rejection reply column 60A and a transmission button 60B for sending a reply result to the execution possibility / rejection reply column 60A to the support server 8 are provided.
When the energy saving action plan selection unit 56 of the support server 8 receives the reply result indicating whether or not execution is possible, only the energy saving action plan that has been answered as executable can be used to give the above advice sentence that instructs more specific action content to the action plan database. 44 (FIG. 4), and is transmitted to the customer side terminal 9 so that it can be browsed as a WEB page.

Next, the implementation status evaluation unit 36 shown in FIG. 2 asks the user on the customer 2 side whether or not the energy saving action plan (advice text) provided by the support server 8 has been executed, and obtains an answer to the question. WEB page data for status confirmation is generated and can be obtained and browsed from the customer side terminal 9.
FIG. 8 is a diagram illustrating an example of the implementation status confirmation screen 62 displayed on the customer side terminal 9.
In this implementation status confirmation screen 62, a list 62A of energy conservation action plans (advice text) already transmitted to the customer side terminal 9 and implementation status confirmation for checking whether or not each energy conservation activity plan has been executed. A field 62B and a transmission button 62C for transmitting the response result to the implementation status confirmation field 62B to the support server 8 are provided.
When the implementation status evaluation unit 36 of the support server 8 receives the response result of the implementation status, it registers the energy conservation action plan already executed by the user on the customer 2 side in the evaluation result database 46 and also proposes the proposed energy conservation action plan. On the other hand, the user's approach to energy saving measures is evaluated according to the ratio of the energy saving action plan executed by the user and / or the degree of decrease in the total power consumption when compared with before the predetermined period. The evaluation result can be viewed from the customer side terminal 9 on the WEB page or the like.

  The energy saving effect evaluation unit 38 shown in FIG. 2 evaluates the reduction of power consumption before and after energy saving measures for each customer 2 and calculates the sum of the reductions in power usage of all the customers 2. The information is published on the WEB page so as to be accessible from each customer side terminal 9.

Next, the operation of this embodiment will be described.
FIG. 9 is a flowchart showing the operation of the support server 8.
As shown in this figure, the main processing of the support server 8 is roughly divided into three parts: a preliminary information registration part, a preliminary power usage status confirmation / action plan proposal part, and an implementation status confirmation part.
The prior information registration part is a processing stage in which information on the customer 2 is input and the use of the support service is started. In order to propose an energy conservation action plan that matches the power usage status of the customer 2, the prior power usage status confirmation / action plan proposal part confirms the power usage status of the customer 2 in advance by measuring the power usage, and This is the stage for proposing energy conservation action plans based on the measurement results. The implementation status confirmation part is a stage in which the implementation status of the proposed energy saving action plan is evaluated based on the measurement results and interviews (questions and answers) to the user on the customer 2 side, and the implementation status is advised.

Hereinafter, each part will be described in more detail.
In the advance information registration part, the support server 8 performs a registration process of information on the customer 2 in order to provide an energy saving support service to the customer 2 (step S1).
Specifically, when the user on the customer 2 side wants to use the support service, a request for starting use of the support service is transmitted from the customer side terminal 9 of the customer 2 to the support server 8. When the support server 8 receives a use start request from the customer side terminal 9, the support server 8 transmits a request for input of customer information 42 (FIG. 3) to the customer side terminal 9 in order to acquire information on the customer 2. Then, the user on the customer 2 side inputs an answer to the requested customer information 42 and transmits it to the support server 8 from the customer side terminal 9. When the support server 8 receives an answer input for the customer information 42, the support server 8 checks whether there is invalid content (missing information) in the answer input content, and then registers it in the customer information database 40.
Thereby, the advance information registration part is completed.

Next, the prior power usage status confirmation / action plan proposal part will be described.
In this part, first, the action plan providing unit 34 of the support server 8 starts to receive the measurement value of the power usage amount of the customer 2 and continues to accumulate the measurement value (step S2), and 6 days have passed. After that (step S3: Yes), a power consumption pattern indicating the power usage status of the customer 2 is determined based on the accumulated measurement value of power usage (step S4).

FIG. 10 is a flowchart of the power consumption type determination process.
For determining this power consumption pattern, as described above, the load duration curve is used, and the power usage status of the consumer 2 is any one of the peak power amount excessively large, the base power excessively large and the normal power excessively large. It is classified into the power consumption pattern.
That is, as shown in the figure, the action plan providing unit 34 of the support server 8 uses the total power consumption to calculate the load duration curve excluding the amount of the always-on device 10A whose power usage is individually measured. A new total power amount is calculated by subtracting the individual power consumption from the amount (step S20). Next, the action plan providing unit 34 calculates a load duration curve after averaging the new total electric energy over 6 days (step S21). As described above, the averaging is performed by averaging the measured values at the same time on each day as described above.
Next, the action plan providing unit 34 calculates the power ratio of the peak power amount, the base power amount, and the normal power amount with respect to each new total power usage based on the load duration curve (step S22), and a certain period of time has elapsed. The result is stored in the evaluation result database 46 for later comparison (step S23). And the action plan provision part 34 specifies the electric energy which is excessive based on each electric power ratio, and the electric power consumption type of the consumer 2 is "peak electric energy excessively large", "base electric energy excessively large" ”Or“ excessive amount of common power ”is determined (step S24).

As a result of the determination, if the corresponding power consumption type does not exist (step S25: Yes), the action plan providing unit 34 determines the power consumption type as an excessive amount of regular power consumption (step S26).
As a result of the determination, when there are a plurality of corresponding power consumption types (step S27: Yes), the action plan providing unit 34 determines that the normal power amount is excessive, the peak power amount is excessive, and the base power amount is excessive. The power consumption type is determined in the order of priority (step S28).
If neither of the steps S25 and S27 corresponds and the power consumption type is uniquely determined (both steps S25 and S27 are both No), the action plan providing unit 34 determines the power consumption type as it is ( Step S29).

  In this way, the power consumption type of the consumer 2 is determined. As described above, the measurement value of the power consumption for about one week is averaged and used for this determination. The period of one week is generally a basic unit of human life (a period in which the lifestyles of weekdays and holidays are cycled), so that a power consumption pattern that matches the user's lifestyle can be obtained. Because it can be considered that the fluctuations in the equipment used due to daily activities and seasons in Japan, it is easy to compare changes in power consumption before and after proposing an energy saving action plan.

  Returning to FIG. 9, the action plan providing unit 34 selects an energy saving action plan to be provided to the user on the customer 2 side based on the determination result and timing of the power consumption type of the customer 2, and the above energy saving action It transmits to the consumer side terminal 9 using the plan provision screen 60 (FIG. 7), and the process which calculates | requires the reply of whether each energy saving action plan is executable from the said customer side terminal 9 is performed (step S5).

FIG. 11 is a flowchart of the action plan selection process.
As shown in the figure, when selecting an energy saving action plan, the action plan providing unit 34 first refers to the customer information 42 in the customer information database 40 and sets the “seasonal home appliance” to the load device 10 included in the customer 2. Is included (step S40). When “seasonal home appliances” are included (step S40: Yes), the action plan providing unit 34 sequentially obtains energy saving action plans corresponding to the “seasonal home appliances” from the action plan database 44 (step S41), and has already been proposed. With reference to the action plan database 45, the already proposed one is deleted (step S42). Then, when there are two or more energy saving action plans for “seasonal home appliances”, the action plan providing unit 34 narrows down to two plans according to a predetermined rule such as the order in which the power consumption of the devices is large (step S43), These plans are registered in the proposed action plan database 45 (step S44). The proposed energy saving action plan registered for the seasonal home appliance is reset every year so that the energy saving action plan is proposed in the next term.
As a result, during the period of use of the seasonal home appliance, a new energy saving action plan is provided to the seasonal home appliance about every four weeks. Therefore, since a new energy saving action plan for seasonal home appliances with relatively large power consumption is provided regularly and constantly, a high energy saving effect can be expected.

Next, the action plan providing unit 34 sequentially acquires the energy saving action plans of the respective load devices 10 corresponding to the power consumption types from the action plan database 44 (step S45), and has already referred to the proposed action plan database 45. The proposed one is deleted (step S46). As a result of these processes, if all have been proposed and no energy saving action plan remains (step S47: Yes), the action plan providing unit 34 changes to another power consumption type (step S48), and this consumption The process returns to step S45 to select an energy saving action plan for the power type. The priority order of the change in the power consumption type is, for example, in the order of excessively large common power amount, excessively large peak power amount, and excessively large base power amount.
When all the energy saving action plans have been proposed for all the power consumption types (step S49: Yes), the action plan providing unit 34 has been proposed by the customer 2 registered in the proposed action plan database 45. After the energy saving action plan is reset (step S50), the processing procedure is returned to step S45, and the energy saving action plan is selected for the power consumption type determined in the power consumption type determination process.
At this time, the action plan providing unit 34 increases or decreases the number of energy saving action plans for the power consumption type, and the sum of the number of energy saving action plans for the seasonal home appliance and the number of energy saving action plans for the power consumption type becomes “4”. (Step S51). Regarding the increase / decrease in the number of energy conservation action plans with respect to the power consumption type, for example, narrow down in order of power consumption, or change the power consumption type to another type to increase the number of energy conservation action plans Used.

  Next, the action plan providing unit 34 registers the energy saving action plan selected for the power consumption type in the proposed action plan database 45 (step S52), and sets the energy saving action plan for each of the seasonal home appliance and the power consumption type. The WEB page data of the energy saving action plan providing screen 60 to be presented to the user is generated (step S53), and the user on the customer 2 side can view it from the customer side terminal 9.

In such an action plan selection process, when the consumer 2 includes a seasonal home appliance, an energy saving measure plan for the seasonal home appliance is always proposed, and thus a proposal that matches the user's power usage situation is possible.
In addition, since the number of proposals for energy saving measures is limited to “4”, the user can execute all the energy saving measures without difficulty and without frustration. Note that the number of proposals for energy saving measures is not limited to “4”, but may be any number that the user can reasonably handle.

Here, as described above, the support server 8 obtains an answer as to whether or not the user can execute the proposed energy saving action plan, and only for the energy saving action plan that is answered as executable. The advice sentence instructing specific action contents is read from the action plan database 44 and transmitted to the customer side terminal 9 as a WEB page so that it can be browsed.
The support server 8 can execute all the proposed energy-saving action plans if no response is obtained from the user after a certain period (for example, 1 day) has passed since the energy-saving action plan was provided to the user. And send an advice sentence about each.
With the above processing, the preliminary power usage status confirmation / action plan proposal part shown in FIG. 9 is completed.

Next, the implementation status confirmation part will be described.
As described above, the implementation status confirmation part is the stage where the implementation status of the proposed energy conservation action plan is evaluated based on the measurement results and interviews (questions and answers) to users on the customer 2 side, and the implementation status is advised. Such an evaluation is performed every other week.
Specifically, as shown in FIG. 9, the support server 8 continues to accumulate and receive the measured value of the power consumption of the customer 2 after the proposal of the energy saving action plan (step S6), 6 Every time the day elapses (step S7: Yes), an implementation status confirmation process is performed (step S8).

FIG. 12 is a flowchart of the implementation status confirmation process.
The implementation status evaluation unit 36 of the support server 8 first generates WEB page data for confirming the actual status for obtaining an answer as to whether or not the energy saving action plan has been executed, and can be obtained and viewed from the customer side terminal 9. To do. Thereafter, the implementation status evaluation unit 36 makes an implementation status confirmation request to the customer side terminal 9 by transmitting a message requesting an answer to the customer side terminal 9 (step S60).
Next, when there is no response input to the implementation status confirmation WEB page (implementation status confirmation screen 62: see FIG. 8) (step S61: No), the implementation status evaluation unit 36 determines the response deadline ( For example, input is waited until one day has passed (step S62: No).

When there is an answer input (step S61: Yes), the implementation status evaluation unit 36 determines the implementation status based on the answer input (step S63). In such a determination, it is determined whether the implementation status corresponds to the implementation of all the proposed energy saving action plans, the implementation of the implementation, or the absence of implementation. And the implementation condition evaluation part 36 selects the energy-saving encouragement advice sentence registered in the action plan database 44 etc. as a fixed sentence beforehand according to a determination result, and a user browses to the consumer side terminal 9 as a WEB page. Send as possible.
If there is no input even after the reply deadline has passed (step S62: Yes), the implementation status evaluation unit 36 determines that no implementation has been performed (step S64).

FIG. 13 is a diagram illustrating a sentence example of the energy saving encouragement advice sentence.
This energy saving encouragement advice sentence is a sentence that evaluates the user's approach to the proposed energy saving action plan. That is, the more energy conservation action plans that are implemented, the more content is used to praise the user. In addition, the energy saving encouragement advice text includes a content that encourages continuation of efforts for energy saving measures.
Such energy saving encouragement advice statements are provided to users every week, which encourages users to save energy and improves continuity.
In addition, since the implementation status is asked by the user every week, it is possible to prevent interruption of efforts due to the user's tiredness and to establish energy saving behavior.

  Next, returning to FIG. 9, after confirming the implementation status, the support server 8 checks the implementation status every 6 days until four weeks have passed since the proposal of the energy saving action plan (step S9: No). . In addition, when 4 weeks have elapsed (step S9: Yes), the support server 8 evaluates the effect of energy saving measures in addition to the confirmation of the implementation status (step S10).

FIG. 14 is a flowchart of an implementation status confirmation / evaluation process.
The energy saving effect evaluation unit 38 of the support server 8 first calculates the load duration curves of the total power usage amount and the individual power usage amount for the latest 27 days (about January) by the load duration curve calculation unit 52. That is, the load duration curve calculation unit 52 calculates the new total power amount by subtracting the individual power consumption amount from the total power consumption amount (step S70), averages the new total power amount over 27 days, and then continues the load duration. A curve is calculated (step S71). Next, the load duration curve calculation unit 52 calculates the power ratio of the peak power amount, the base power amount, and the normal power amount with respect to each new total power usage based on the load duration curve (step S72).

Next, the energy saving effect evaluation unit 38 calculates a power consumption reduction rate (step S73). Specifically, the energy saving effect evaluation unit 38 compares the respective areas of the load duration curve obtained from the measured value before the energy saving measure is taken (before the energy saving action plan is proposed) and the current load duration curve. The power consumption reduction rate is calculated for each of the total power consumption and the individual power consumption.
Here, the amount of power reduced by implementing energy-saving measures is usually smaller than the total power consumption, and the power consumption depends on the lifestyle changes of the user on the consumer 2 side and the presence or absence of events. Since it is easy to be influenced, even if the energy saving action plan is executed, it may be assumed that all of the actions do not lead to a reduction in power consumption. In this case, if the effect of the user's efforts for energy saving measures is evaluated only by the reduction rate of the power consumption, the evaluation becomes worse and the user's motivation may be lost.
Therefore, in this embodiment, the implementation status of the energy saving action plan is included in the evaluation target, and the effect of the user's efforts for energy saving measures is evaluated.
The procedure for confirming the implementation status of this energy saving action plan is substantially the same as the processing shown in FIG. 12, and the same processing steps are denoted by the same reference numerals and description thereof is omitted.

Next, the energy saving effect evaluation unit 38 performs energy saving determination for evaluating the effect of the user's efforts for energy saving measures based on the reduction rate of the power consumption and the implementation status (step S74). In such a determination, for example, 1) When all energy conservation action plans are implemented and power consumption is reduced, 2) When all energy conservation action plans are implemented, but power consumption is not reduced 3) There is an unimplemented energy conservation action plan, but the power consumption is reduced. 4) When no energy conservation action plan is implemented, it is determined which corresponds.
And the energy saving effect evaluation part 38 selects the energy saving encouragement advice sentence mentioned above according to the determination result, and transmits to the consumer side terminal 9 so that a user can browse as a WEB page.
In the energy saving encouragement advice sentence at this time, as shown in the fixed sentence 4 in FIG. 13, for example, the more energy saving action plans are implemented and the more the power consumption is reduced, the more the user is praised. Sentences with content to be used In addition, the energy saving encouragement advice text includes the content that encourages the user to continue the efforts for energy saving measures, as in the case of checking the implementation status described above.

  Furthermore, the energy saving effect evaluation unit 38 adds the reduction amount of the power consumption for each customer 2 and calculates the reduction amount of the power consumption by all the consumers 2. Can be viewed. As a result, each user can recognize that even if the reduction amount of power consumption at each individual customer 2 is small, a large reduction in power consumption is obtained as a whole, and each user 2 has a willingness to save energy. You can continue.

Further, along with the evaluation result by the energy saving effect evaluation unit 38, the action plan providing unit 34 reads out the advertisement information associated with the load device 10 which is the target of the energy saving action plan from the advertisement information database 47, and this advertisement. The user can browse the information from the customer side terminal 9 together with the evaluation result.
Thereby, for example, for a user who uses the old load device 10, it is possible to obtain information on a product with a higher energy saving effect.

Returning to FIG. 9 again, when the implementation status confirmation / evaluation for the fourth week is completed, the support server 8 determines the power consumption type of the customer 2 based on the load duration curve calculated in the process of this evaluation, and performs the determination. In order to propose an energy saving action based on the result, the processing procedure is returned to step S4.
Thereby, since the power consumption type of the consumer 2 is reviewed every four weeks, it is possible to continue to propose an appropriate energy saving action plan following the power usage situation of the user changing by taking the energy saving action plan.

As described above, according to the present embodiment, the measurement of the power consumption amount of the consumer 2 and the transmission of the energy saving action plan according to the measurement result to the consumer side terminal 9 are, for example, at intervals of 4 weeks or the like. At regular intervals.
As a result, energy conservation action plans are regularly reviewed according to the power usage status of consumers, and users are always provided with energy conservation action plans that match the power usage status. This makes it possible to continuously take energy conservation actions without feeling bored.

Moreover, according to this embodiment, the energy-saving action plan which prescribed | regulated the handling of the load apparatus 10 with which reduction of electric power consumption is anticipated among the load apparatuses 10 with which the consumer 2 is equipped as an energy-saving action plan to the consumer side terminal 9 Sent.
Thus, the user can easily know which load device 10 should be handled in order to save energy, and does not make it difficult to take energy saving action. Can be easily executed.

  Further, according to the present embodiment, since the implementation status confirmation of the energy conservation action plan and the evaluation on the implementation status are periodically performed (for example, every other week) for the user, the user's motivation for the energy conservation behavior is prevented from being lowered. be able to.

  Further, according to the present embodiment, when the support server 8 transmits the energy saving action plan to the customer side terminal 9, since it transmits the energy saving action plan that has already been transmitted, the energy saving action plan that has already been proposed to the user. Is prevented from being proposed again, and only new action plans can be proposed.

Moreover, according to this embodiment, since the evaluation of the energy saving effect in the customer 2 and the transmission of the result of the evaluation are performed periodically (for example, every four weeks), the user's willingness to save energy is prevented from decreasing. be able to.
At this time, since the support server 8 calculates the reduction amount of the power consumption by all the consumers 2 and enables the user to view from each consumer side terminal 9, the power consumption by each consumer 2 Even if the amount of reduction is small, each user can recognize that a large reduction in power consumption is obtained as a whole, and can continue to be eager to save energy.

Further, according to the present embodiment, the support server 8 obtains a load duration curve of the power usage amount, and the power usage amount is excessive based on the peak power amount, the base power amount, and the normal power amount in the load duration curve. The load device 10 is specified.
As a result, among the load devices 10 included in the consumer 2, the load device 10 having a relatively excessive power consumption is identified from the measured value of the overall power consumption of the consumer 2. For this reason, since it is not necessary to measure the electric power consumption of each load apparatus 10 separately, the number of the instruments required for an electric power consumption measurement can be restrained, installation property improvement and cost reduction can be aimed at.

  Moreover, according to this embodiment, since the load apparatus 10 with which the use time was prescribed | regulated is classified into a seasonal household appliance and the load apparatus 10 which does not correspond to a seasonal household appliance is classified into the 1st-3rd apparatus, a seasonal household appliance is another It is preferentially distinguished from the load device 10. Since the seasonal home appliance can reliably determine whether or not the consumer 2 is used based on the time of use, the load appliance 10 used by the consumer 2 can be more reliably identified and energy-saving behavior for the load appliance 10 can be determined. Proposal can be provided.

Furthermore, seasonal household appliances include air-conditioning equipment such as air conditioners that consume a large amount of power during operation and consume standby power. In other words, during the period when air conditioning equipment is used, the curve shape of the load duration curve varies greatly depending on the power usage of the air conditioning equipment, affecting the overall peak power, base power, and normal power consumption. Therefore, it is difficult to determine the excessive power consumption of the first to third devices from the shape of the load duration curve, and it becomes difficult to provide an appropriate energy saving action plan.
On the other hand, according to the present embodiment, such air conditioning devices are preferentially distinguished as seasonal home appliances, and the presence or absence of use of the seasonal home appliances is determined according to the time of use. Appropriate energy saving action plan can be provided. Moreover, it is estimated that the load duration curve obtained after provision of the energy saving action plan is a result of using the air-conditioning apparatus based on the energy saving action plan. That is, from the curve shape of the load duration curve, it is possible to determine an excess of the power usage of the first to third devices without considering the influence of seasonal home appliances. Energy conservation action plan can be provided.

  In addition, according to the present embodiment, the advertisement information that prompts the user to replace the load device 10 as the target of the energy saving action plan is provided to the user. As a result, replacement with a new product with less power consumption is promoted, and the energy saving effect is enhanced. For users who are using old products, useful information can be obtained about products that are candidates for replacement.

  In addition, embodiment mentioned above shows the one aspect | mode of this invention to the last, and a deformation | transformation and application are arbitrarily possible within the scope of the present invention.

  For example, in the above-described embodiment, the configuration is such that the load device 10 having an excessive power usage amount is specified by measuring the total power usage amount of the consumer 2 and calculating the load duration curve. However, the present invention is not limited to this, and each load device 10 is provided with an individual measuring device 20 that individually measures the power used, and the support server 8 loads the load based on the power usage measured by each individual measuring device 20. A configuration may be adopted in which it is determined whether or not the power usage amount is excessive for each device 10, and an energy saving action plan is selected for the load device 10 determined to be excessive. Whether or not the power usage amount is excessive can be determined by, for example, setting a threshold value for the power usage amount in advance for each load device 10 and comparing it with the threshold value.

Further, in the above-described embodiment, the load duration curve is calculated using all the measured values of the power consumption accumulated over a predetermined period such as 6 days or 27 days.
However, the load duration curve may be calculated by selecting only the measured values on the day that can be regarded as the same living behavior among the data within the predetermined period.

In detail, since the trend of power consumption is likely to be affected by fluctuations in the behavior of the customer 2, the measured value of the power consumption used to evaluate the implementation status of energy conservation measures is performing the same behavior. It is desirable to select (filter) and evaluate possible days.
Therefore, in order to filter the days that are considered to be performing the same action, the amount of power consumption for each time zone (midnight, morning, morning, afternoon, evening, night) is calculated, and the standard day The power consumption of each time is compared with the power consumption of each time zone.
If the value of the power consumption amount in each time zone is within 20% (for example, only an example) with respect to the reference power consumption amount, the behavior is the same and is adopted in the analysis data.
The power consumption used as a reference here is the power usage status data of the customer 2 measured in advance at the start of the service, and thereafter the average value of the measurement results of the power usage measured during the four weeks. Are sequentially updated as reference data.
Thereby, for example, even when an event that greatly changes the life style such as travel or business trip and has a great influence on the trend of power consumption occurs, the influence can be kept to a minimum.

For example, it is good also as a structure which can receive the comparison (user ranking) of the electric power consumption of the consumers 2 by the consumer side terminal 9. FIG.
In this ranking, since the use start date of the support service differs depending on the user, it is desirable that the power consumption to be compared is the same month or the same year. In addition, the ranking includes overall power consumption ranking, regional power consumption ranking, power consumption ranking by number of family members, power consumption ranking by detached homes and apartments, power consumption ranking by total floor area, whether or not all electrification Another power consumption ranking can be used.
In the ranking display, the power consumption is displayed as a graph with an icon such as an animal, so that children can be interested in energy saving measures.
