  In order to reduce energy consumed by businesses such as companies and local governments, services by ESCO (Energy Service Company) are being implemented. ESCO is a consumption limit control device (for example, a demand controller) that replaces an existing non-energy-saving device with an energy-saving device or limits the amount of energy consumed by the device per unit time to an upper limit or less at a target facility of an operator. ) To reduce energy consumption at target facilities. In the following, such an ESCO service is referred to as an ESCO service, and an operator (for example, a company or a local public entity) receiving the ESCO service is referred to as a service user.

The ESCO service is described in Patent Documents 1 and 2 below, for example.
According to Patent Document 1, the ESCO installs an energy saving device in a service user's facility, and the service user pays a part of the cost reduced by the energy saving device to the ESCO.
According to Patent Document 2, an energy saving device is installed in a service user's facility, and the energy saving device owned by ESCO and the device owned by the service user are connected to the monitoring control device. This facilitates device management.

  In the ESCO service, the service user does not incur the cost of acquiring the energy saving device, so the initial cost incurred by the service user is zero. As a result, the spread of ESCO services can be expected.

2.1. FIG. 2 is a flowchart showing an output method of energy reduction amount data as a predicted value before replacing a non-energy-saving device with an energy-saving device. FIG. 2 shows a case where an energy reduction amount data output method as a predicted value is performed before replacing the non-energy-saving device 1a with the energy-saving device 1b in a plurality of energy supply systems of the target facility F.

  First, in step S0, a set period is determined. The set period is, for example, one day (24 hours), one week, one month, or one year.

In step S <b> 1, in the target facility F, consumption data before replacement of the energy supply system is measured by the data acquisition device 7 for each energy supply system.
For example, for each energy supply system, the data acquisition device 7 measures the energy consumption and consumption time of the unit time in the energy supply system as consumption data before replacement (note that the energy consumption of unit time and The product of consumption time is energy consumption over a set period). More specifically, in step S1, for each energy supply system, the data acquisition device 7 determines, in the target facility F, the energy consumption per unit time of the energy supply system and the set period (hereinafter simply set in step S0). The time during which the energy supply system consumes energy in the period (hereinafter simply referred to as consumption time) is measured as consumption data before replacement. When the energy consumption amount per unit time of the energy supply system varies, the energy consumption amount per unit time of the energy supply system is an average value over the consumption time (the same applies hereinafter).
Instead, in step S1, for each energy supply system, the data acquisition device 7 integrates the energy consumption amount in a minute time with time over a set period (that is, an integral value) and the above-described consumption time (described later). May be measured as consumption data before replacement in the energy supply system. This integrated value is the energy consumption amount of the energy supply system over the set time.

  In step S2, the storage device 3b of the output device 3 stores consumption data before replacement of the energy supply system measured in step S1 for each energy supply system. In this embodiment, in step S2, consumption data before replacement of each energy supply system measured in step S1 is output via the Internet 9 by the data acquisition device 7 having a function of connecting to the Internet 9. 3 communication device 3a. Thereby, consumption data before replacement of each energy supply system is stored in the storage device 3 b of the output device 3. The consumption amount data of each energy supply system includes the above-described consumption time.

  On the other hand, in step S3, the storage device 3b of the output device 3 replaces the consumption data related to the energy consumption of the energy supply system after replacing the non-energy-saving device 1a with the energy-saving device 1b for each energy supply system. As consumption data. For example, storage of consumption data of the energy supply system may be performed as follows. For each energy supply system, in a state where the non-energy-saving device 1a is temporarily replaced with the energy-saving device 1b, the energy consumption amount per unit time of the energy supply system is measured by the data acquisition device 7 as consumption data after replacement. To do. The exchanged consumption data measured for each energy supply system is transmitted from the data acquisition device 7 to the communication device 3 a of the output device 3 via the Internet 9. Thereby, consumption data (energy consumption per unit time) after replacement of each energy supply system is stored in the storage device 3b of the output device 3.

  In step S4, the calculation device 3c of the output device (server) 3 stores the consumption data before replacement stored in the storage device 3b in step S2 and the storage device 3b in step S3 for each energy supply system. Based on the consumption data after replacement, an energy reduction amount obtained by replacing the non-energy-saving device 1a with the energy-saving device 1b in the energy supply system is calculated as a predicted value.

  For example, in step S1, for each energy supply system, the data acquisition device 7 calculates the energy consumption and consumption time per unit time (the product of both becomes the energy consumption over the set period), the consumption before replacement. When measured as data, in step S4, for each energy supply system, the product of the unit time energy consumption stored in step S2 and the consumption time stored in step S2 is stored in step S3. The difference between the stored energy consumption amount per unit time of the energy supply system and the consumption time stored in step S2 is calculated as an energy reduction amount. Similarly, in step S1, when the data acquisition device 7 measures the energy consumption amount and consumption time per unit time as consumption data before replacement for each energy supply system, in step S4, the energy supply system Every time, the difference between the energy consumption per unit time of the energy supply system stored in step S2 and the energy consumption per unit time of the energy supply system stored in step S3 and the consumption time stored in step S2 The product may be calculated as an energy reduction amount.

  On the other hand, when the above-described integral value is measured in step S1, the energy consumption amount (the above-mentioned integral value) of the energy supply system over the set time stored in step S2 for each energy supply system in step S4. The difference between the product of the unit time energy consumption stored in step S3 and the consumption time stored in step S2 is calculated as the energy reduction amount.

  In step S4, the energy reduction amount of each energy supply system calculated as described above is stored in the storage device 3b.

In step S5, when the communication device 3a of the output device (server) 3 receives a data request for the energy reduction amount from the client terminal 5 via the Internet 9, each energy stored in the storage device 3b of the output device 3 is received. A web page including data on the energy reduction amount (predicted value) of the supply system is transmitted (that is, output) to the client terminal 5 via the Internet 9. Thereby, the energy reduction amount of each energy supply system is displayed on the display 5a of the client terminal 5. Thus, since the energy reduction amount is indicated on the displayed web page, a person can see the energy reduction amount and know the predicted value of the energy reduction amount.
In the web page described above, the energy reduction amount data of each energy supply system is displayed with the energy supply system and the energy reduction amount associated with each other.

  Regarding step S5, a data request from the client terminal 5 to the communication device 3a of the output device 3 may be made by an appropriate method. For example, a person causes the web browser of the client terminal 5 to make a data request to the communication device 3a of the output device 3 using the input means (mouse, keyboard, touch panel, etc.) of the client terminal 5.

  As described above, when the communication device 3 a of the output device 3 receives a data request from the client terminal 5 via the Internet 9, a web page including energy reduction amount data as a predicted value by communication with the client terminal 5. Is transmitted to the client terminal 5. As a result, the web page is displayed on the display 5 a of the client terminal 5. Therefore, the service use examiner can easily grasp the predicted value of the energy reduction amount obtained by the ESCO service for each energy supply system simply by looking at the website on the display 5a of the client terminal 5, and the energy reduction amount can be reduced. Guaranteed. This makes it easier for a service utilization examiner to quickly decide to receive the ESCO service.

2.2. FIG. 3 is a flowchart showing a method of outputting energy reduction amount data after replacing a non-energy-saving device with an energy-saving device. FIG. 3 shows a case where the energy reduction amount data output method is performed after the non-energy-saving device 1a is replaced with the energy-saving device 1b in the plurality of energy supply systems of the target facility F. 3 may be performed for the same target facility F as in FIG. 2 after the energy reduction amount data output method of FIG. 2 is performed.

  First, in step S10, a set period is determined. The set period is, for example, one day (24 hours), one week, one month, or one year.

In step S11, in the target facility F, for each energy supply system, consumption data after replacement of the energy supply system in which the non-energy-saving device 1a is replaced with the energy-saving device 1b is measured by the data acquisition device 7.
For example, for each energy supply system, the data acquisition device 7 measures the energy consumption and consumption time per unit time as the consumption data after replacement (note that the product of the energy consumption and consumption time per unit time). Becomes energy consumption over a set period). More specifically, in step S11, for each energy supply system, the data acquisition device 7 determines, in the target facility F, the energy consumption per unit time of the energy supply system and the set period (hereinafter simply set in step S10). The time during which the energy supply system has consumed energy (hereinafter also simply referred to as consumption time) in the period) is measured as consumption data after replacement.
Instead, in step S11, for each energy supply system, the data acquisition device 7 integrates the energy consumption amount in a minute time with time over a set period (that is, the integral value) and the above-described consumption time (described later). May be measured as consumption data after replacement in the energy supply system. This integrated value is the energy consumption amount of the energy supply system over the set time.

  In step S12, the storage device 3b of the output device 3 stores the consumption data after replacement of the energy supply system measured in step S11 for each energy supply system. In this embodiment, in step S12, the consumption data after replacement of each energy supply system measured in step S11 is output via the Internet 9 by the data acquisition device 7 having a function of connecting to the Internet 9. 3 communication device 3a. Thereby, consumption data after replacement of each energy supply system is stored in the storage device 3 b of the output device 3. The consumption amount data of each energy supply system includes the above-described consumption time.

  On the other hand, in step S13, by the storage device 3b of the output device 3, the energy consumption per unit time of the energy supply system before replacing the non-energy-saving device 1a with the energy-saving device 1b is determined by an appropriate method for each energy supply system. And stored as consumption data before replacement. For example, this step 13 may be step S2 described above. That is, the energy consumption per unit time of each energy supply system stored in step S2 described above may be consumption data stored in step S13.

  In step S14, the consumption data after replacement stored in the storage device 3b in step S12 and the storage device 3b in step S13 are stored for each energy supply system by the arithmetic device 3c of the output device (server) 3. Based on the consumption data before replacement, an energy reduction amount obtained by replacing the non-energy-saving device 1a with the energy-saving device 1b in the energy supply system is calculated.

  For example, in step S11, for each energy supply system, the data acquisition device 7 calculates the energy consumption amount and the consumption time per unit time (the product of both becomes the energy consumption amount over the set period) and the consumption amount before replacement. When measured as data, in step S14, for each energy supply system, the product of the unit time energy consumption stored in step S12 and the consumption time stored in step S12 is stored in step S13. The difference between the stored energy consumption amount per unit time of the energy supply system and the consumption time stored in step S12 is calculated as an energy reduction amount. Similarly, in step S11, when the data acquisition device 7 measures the energy consumption amount and consumption time per unit time as consumption data before replacement for each energy supply system, in step S14, the energy supply system Every time, the difference between the unit time energy consumption of the energy supply system stored in step S12 and the unit time energy consumption of the energy supply system stored in step S13, and the consumption time stored in step S12. The product may be calculated as an energy reduction amount.

  On the other hand, when the above-described integral value is measured in step S11, in step S14, for each energy supply system, the energy consumption amount (the above-mentioned integral value) of the energy supply system over the set time stored in step S12. The difference between the product of the unit time energy consumption stored in step S13 and the consumption time stored in step S12 is calculated as the energy reduction amount.

  In step S14, the energy reduction amount of each energy supply system calculated as described above is stored in the storage device 3b.

In step S15, when the communication device 3a of the output device 3 (server) receives a data request for energy reduction from the client terminal 5 via the Internet 9, each energy stored in the storage device 3b of the output device 3 is received. A web page including data on the energy reduction amount of the supply system is transmitted (that is, output) to the client terminal 5 via the Internet 9. Thereby, the energy reduction amount of each energy supply system is displayed on the display 5a of the client terminal 5. Thus, since the energy reduction amount is shown on the displayed web page, a person can see this to know the energy reduction amount.
In the web page described above, the energy reduction amount data of each energy supply system is displayed with the energy supply system and the energy reduction amount associated with each other.

  Regarding step S15, the data request from the client terminal 5 to the communication device 3a of the output device 3 may be made in the same manner as in step S5 described above.

  As described above, when the communication device 3 a of the output device 3 receives a request from the client terminal 5 via the Internet 9, the communication device 3 a communicates with the client terminal 5 to display a web page including energy reduction amount data on the client terminal 5. Send to. As a result, the web page is displayed on the display 5 a of the client terminal 5. Therefore, the service user can easily grasp the energy reduction amount obtained by the ESCO service for each energy supply system simply by looking at the website on the display 5a of the client terminal 5.

  Preferably, the energy reduction amount data output method further includes steps S16 to S18 as shown in FIG.

  In step S16, the arithmetic device 3c of the output device 3 is based on part or all of the energy reduction amounts (total values) of the plurality of energy supply systems calculated in step S14 and the designated cost calculation criteria. An amount corresponding to the part or all of the energy reduction amount is calculated. The cost calculation standard is stored in advance in the storage device 3b. The cost calculation standard may be an energy unit price, for example. In this case, the arithmetic unit 3c multiplies the energy unit price by part or all of the energy reduction amounts of the plurality of energy supply systems calculated in step S14, thereby calculating the amount corresponding to the part or all of the energy reduction amount. Is calculated. The calculated amount is stored in the storage device 3b.

  In step S17, the account management device (for example, the communication device 3a) provided in the output device 3 sets the amount calculated by the arithmetic device 3c and stored in the storage device 3b via the Internet 9 or another network. Then, a process of transferring from the first financial institution account to another set (second) financial institution account is performed. Thereby, a part or all of the amount saved by the ESCO service is automatically stored in the second financial institution account.

  When step S17 is completed, the process returns to step S11. That is, when the above-described setting period has elapsed since the previous step S11, steps S11 to S14, S16, and S17 are performed again. In this way, steps S11 to S14, S16, and S17 are repeated. As a result, the sum of the amounts calculated in the multiple times of step S16 is stored in the storage device 3b as the accumulated amount. In the stage where step S16 is performed only once, the accumulated amount is equal to the amount calculated in step S16.

  In step S18, when the communication device 3a of the output device 3 receives a data request for the accumulated amount from an appropriate terminal (for example, the client terminal 5 described above) via the Internet 9, the storage device 3b of the output device 3 A web page including the accumulated amount data stored in is transmitted to the terminal via the Internet 9. Thereby, the accumulated amount is displayed on the display of the terminal (for example, the display 5a of the client terminal 5 described above). Thus, since the accumulated amount is shown on the displayed web page, the person can see the accumulated amount by seeing this.

  In Step S15 after repeating Steps S11 to S14, S16, and S17, a web page including data on energy reduction amounts of the respective energy supply systems for all of the plurality of setting periods respectively corresponding to the plurality of Steps S11. The communication device 3a may transmit to the client terminal 5, or the communication device 3a may transmit a web page including data on the energy reduction amount of each energy supply system regarding a part of the setting periods. You may transmit to the client terminal 5. In the latter case, the data request including information specifying a part of the setting period is made from the client terminal 5 to the communication device 3a in step S15.

For example, Step S1, Step S2, Step S3, Step S11, Step S12, and Step S13 may be performed for one energy supply system in the target facility F. In this case, the following is performed.

  In step S4, consumption data before replacement stored in the storage device 3b in step S2 by the arithmetic device 3c of the output device (server) 3 and consumption data after replacement stored in the storage device 3b in step S3.

8). Modification Example 6
In the above description, the non-energy-saving device 1a provided in the energy supply system is replaced with the energy-saving device 1b. However, the present invention is not limited to this.
That is, the target facility F is provided with an energy supply system, and the energy supply system is provided with an energy consuming device that is the non-energy-saving device 1a or another device, and the energy supply system includes the energy consuming device. In addition, when power or combustion gas (city gas, propane gas, etc.) is supplied as an energy medium and the energy consuming device consumes the energy medium, a consumption limit control device (for example, demand demand) is supplied to the energy supply system. Data on the amount of energy reduction when performing construction for providing a controller) may be output as a predicted value.

  The consumption limit control device prevents the amount of energy medium consumed by the energy consuming device per unit time from exceeding the upper limit value L1, or the amount of energy medium flowing through the energy supply system per unit time exceeds the upper limit value L2. Control the energy consuming equipment so that there is no. In the former case, the consumption restriction control device monitors the amount that the energy consuming device consumes the energy medium per unit time, and when the amount approaches the upper limit value L1 (that is, the amount is smaller than the upper limit value L1). When reaching a value that is smaller by the set value), the energy consuming device is controlled so as to reduce the amount of energy medium consumed by the energy consuming device per unit time. In the latter case, the consumption restriction control device monitors the amount of the energy medium flowing through the energy supply system per unit time, and when the amount approaches the upper limit value L2 (that is, the amount is set to be smaller than the upper limit value L2). When the value is reduced by a small value, the energy consuming device is controlled so as to reduce the amount of energy consuming device provided in the energy medium that consumes the energy medium per unit time.

  When one energy consuming device is provided in one energy supply system, the amount of energy medium flowing through the energy supply system per unit time is the amount that the energy consuming device consumes the energy medium per unit time. It is. On the other hand, in the case where a plurality of energy consuming devices are provided in one energy supply system, the amount of energy medium flowing through the energy supply system per unit time is such that the plurality of energy consuming devices use the energy medium per unit time. This is the total amount consumed.

  In addition, when a plurality of energy consuming devices are provided in one energy supply system, the consumption restriction control device controls at least one of the plurality of energy consuming devices after the construction. That is, in one energy supply system, one consumption restriction control device may control a part or all of a plurality of energy consuming devices, and each of the plurality of consumption restriction control devices has a plurality of energy consumption. The consumer device may be controlled.

  Further, in the case where a plurality of energy consuming devices are provided in one energy supply system and the above-described upper limit value L1 is used, one consumption limit control device is provided in a plurality of energy supply systems. By controlling part or all of the energy consuming equipment, the amount of energy medium consumed per unit time by the energy consuming equipment for each energy consuming equipment may not exceed the upper limit L1. The total amount of energy medium consumed per unit time from the part or all of the energy medium may not exceed the upper limit L1, and one consumption restriction control device may be one of a plurality of energy consuming devices. By controlling one, the amount of the energy medium consumed per unit time by the one energy consuming device may not exceed the upper limit value L1.

In the present modification 6, unlike the above, the following processing is performed instead of steps S1 to S4.
The data acquisition device 7 at each time when the amount of energy medium consumed by the energy consuming device per unit time exceeds the upper limit value L1 in the set period before the construction (that is, the period set in step S0). By measuring the excess amount (C1-L1) that the amount C1 has exceeded from the upper limit value L1, and performing a construction to install a consumption restriction control device in the energy supply system based on the measured excess amount at each time point Obtain the amount of energy reduction that can be obtained. For example, the data acquisition device 7 determines that the amount C1 is the upper limit over the time T during which the amount of energy medium consumed by the energy consuming device per unit time exceeds the upper limit during the set period before the construction. The energy reduction amount is obtained by time-integrating the excess amount (C1-L1) exceeding the value L1.
Alternatively, the data acquisition device 7 determines that the energy acquisition unit 7 at each time when the amount of the energy medium flowing through the energy supply system per unit time exceeds the upper limit value L2 in the set period before the construction (that is, the period set in step S1). The excess amount (C2-L2) that the amount C2 exceeds from the upper limit value L2 is measured, and the energy reduction amount obtained by performing the construction is obtained based on the measured excess amount at each time point. For example, in the data acquisition device 7, the amount C2 exceeds the upper limit value L2 over the time T during which the amount of energy medium flowing through the energy supply system per unit time exceeds the upper limit value in the set period before the construction. The energy reduction amount is obtained by time integration of the excess amount (C2-L2).

  When the target facility F is provided with a plurality of energy supply systems, the energy reduction amount by the construction is obtained for each energy supply system as described above.

  The energy reduction amount thus obtained is stored in the storage device 3b, and then step S5 is performed. In the sixth modification, the arithmetic device 3c is omitted.

  The points not described in the sixth modification are the same as described above. That is, the above-described contents are all applied in the sixth modification except for the contents of the above-described item 2.2 (after replacing the non-energy-saving device with the energy-saving device). In this case, however, the above-mentioned content is replaced with “energy-consuming device” for “non-energy-saving device” and “energy-saving device”, and the content “replace non-energy-saving device with energy-saving device” is “consumed in the energy supply system”. It should be read as “providing a quantity limiting control device”.
