  Here, in the tenant building, since the tenant normally pays the amount of energy used, the energy saving effect caused by the capital investment by the owner becomes a merit on the tenant side. In addition, even if the owner tries to collect a separate amount from the tenant to meet the investment cost recovery, the tenant's consent may not be obtained. In this case, the owner cannot directly receive the merit of the energy saving effect, and it is difficult to recover the invested funds. Therefore, the capital investment for the tenant building by the owner is not appropriate. For this reason, there is a problem that it is difficult for the owner to promote the capital investment in the tenant building.

  On the other hand, a tenant who obtains the owner's consent may make a capital investment at his own expense. However, it is not clear whether an energy saving effect that can recover the cost required for capital investment is obtained, and such risky capital investment is likely to be avoided. For this reason, capital investment by tenants is also unlikely to be promoted as in the case of owners.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a fee calculation device, a fee calculation system, and a fee calculation program capable of promoting capital investment for obtaining an energy saving effect. There is.

  The charge calculation device of the first invention is a charge calculation device when energy-saving equipment / service is introduced into equipment with a predetermined energy-saving investment cost, and includes a storage unit, a data reception unit, a calculation unit, And an output unit. The storage unit stores a predetermined energy saving investment cost and a pre-introduction energy cost related to the energy usage of the facility in a predetermined period before the introduction of the energy saving device / service. The data receiving unit receives the post-introduction energy cost related to the energy usage of the facility in a period corresponding to a predetermined period after the introduction of the energy saving device / service. The calculation unit calculates an energy saving cost that is a difference between the energy cost before introduction and the energy cost after introduction, and is a cost that is less than the energy saving cost and that reflects at least a predetermined energy saving investment cost. Is calculated. The output unit outputs the cost calculated by the calculation unit. Examples of the output unit include a connection port for connecting to a display or printer as an external output device via a cable, a network, or the like. In addition, as an energy-saving apparatus here, the equipment etc. which can reduce the energy amount consumed while maintaining the comfort before introduction are mentioned, for example. Moreover, as an energy saving service, for example, a service such as reducing energy loss by monitoring or controlling operation of equipment used before introduction can be given. Examples of the data receiving unit here include a connection port for receiving data via a network, an interface for receiving data stored in a recording medium or the like, or data input from a keyboard.

  In a tenant building or the like, the tenant usually pays the amount of energy used, and the energy saving effect caused by the capital investment by the owner becomes a merit for the tenant. On the other hand, the owner may not be able to obtain the tenant's consent even if he / she tries to collect a separate amount from the tenant to meet the cost recovery required for capital investment. In this case, the owner cannot directly receive the merit of the energy saving effect, and it is difficult to recover the invested funds, so that the capital investment for the tenant building by the owner is not worth the investment. For this reason, it is difficult for owners to promote capital investment in tenant buildings.

  On the other hand, in the fee calculation device according to the first aspect of the invention, the calculation unit calculates a split cost that is a part of the energy saving cost corresponding to the energy saving effect. In addition, a predetermined energy saving investment cost is reflected in this split cost. For this reason, the output unit can output information on the split cost so that a predetermined energy saving investment cost can be covered by the split cost which is a part of the energy saving cost. In addition, when reflecting the predetermined energy-saving investment cost in the split cost, for example, a part of the initial investment included in the predetermined energy-saving investment cost is a part of the split cost, For example, the case of split repayment. According to the split cost grasped in this way, the share of the tenant can be made the total cost of the post-introduction energy cost and the split cost. As for the total cost of post-installation energy costs and split costs borne by the tenant, the owner pays the post-installation energy costs to the energy supplier, and the split costs are the predetermined energy savings that are the price for the energy-saving equipment / service provider. Since it can be an investment cost, a predetermined energy saving investment cost can be covered within the total cost of the tenant. Here, the predetermined energy saving investment cost includes initial investment required for renovation work at the time of introduction of the energy saving device / service, and consideration of the subsequent energy saving service by the energy saving device / service provider.

  As a result, the tenant can pay the cost lower than the pre-introduction energy cost by the total cost of the post-introduction energy cost and the split cost without taking the risk of bearing the prescribed energy-saving investment cost by itself. Benefits are gained. Further, the owner can obtain a merit that the predetermined energy saving investment cost can be covered by a part of the cost borne by the tenant. Thus, by using the information about the fee output by this fee calculating device, it becomes possible to improve the considence of the fee structure of both the tenant and the owner.

In this way, the fee structure obtained from the fee calculation device enables the owner and the tenant to make a contract with a high degree of convincing via the energy-saving device / service provider. / It becomes possible to promote the introduction of services.
The fee calculation device of the second invention is the fee calculation device of the first invention, and the storage unit stores a guaranteed energy cost that is lower than the energy cost before introduction by a predetermined guaranteed cost. When the post-introduction energy cost exceeds the guaranteed energy cost, the calculation unit calculates a warranty target cost that is a difference between the post-introduction energy cost and the guaranteed energy cost.

  Here, the guaranteed cost is calculated when the post-introduction energy cost exceeds the guaranteed energy cost stored in the storage unit and the guaranteed energy saving effect cannot be obtained. For this reason, even if energy-saving devices / services have been introduced, even if the prescribed energy-saving effect cannot be obtained, the energy-saving devices / service providers should be guaranteed the amount of money that is calculated for the warranty costs. Can do. Accordingly, it is possible to reduce the risk borne by the person related to the introduction of the energy saving device / service and to further promote the introduction of the energy saving device / service.

The charge calculation device of the third invention is the charge calculation device of the first invention or the second invention, and the calculation unit calculates the post-introduction cost obtained by summing the post-introduction energy cost and the split cost.
Here, the fee calculation device calculates the post-introduction cost obtained by summing the post-introduction energy cost and the split cost. As a result, the post-installation cost that the tenant should pay can be directly grasped by the output from the output unit.

  A fee calculation device according to a fourth aspect of the present invention is the fee calculation device according to any one of the first to third aspects, wherein the storage unit saves energy for each user when there are a plurality of users of energy-saving devices / services. Stores individual specification data related to the specification of the device / service.

<Outline of the invention>
The present invention provides a fee calculation device capable of promoting capital investment for obtaining an energy saving effect.
When the tenant building owner makes a capital investment to an energy-saving company in order to obtain an energy-saving effect, the fee calculation device of the present invention is provided for each of the energy saving company (for example, ESCO company), owner, and tenant. It is possible to obtain specific information about the fee payment system that ensures convincing. By following this fee payment system, energy-saving companies can collect funds required for capital investment (energy-saving investment costs for the introduction of energy-saving equipment, energy-saving services, etc.) out of the cost-effective costs caused by capital investment, There is an advantage that the introduction can be expected to be promoted. In addition, owners do not have to follow the investment burden and risks themselves, and energy-saving equipment / services can be introduced into tenant buildings, which can increase the value of the property and the ability to attract customers. . Furthermore, for tenants, there is an advantage that the energy fee paid before the introduction of the energy saving service is reduced after the introduction.

That is, according to the charge calculation device of the present invention, in the charge payment system between the energy saving business operator, the tenant building owner, and the tenant, information on a fair and highly convincing contract payment system can be obtained. / The introduction of services can be promoted.
<Embodiment of the present invention>
Next, the energy saving service providing system of the present invention will be described by taking as an example energy saving related to an electricity bill for each predetermined period.

<Outline of energy-saving service provision system>
An outline of an energy saving service providing system in which an embodiment of the present invention is adopted is shown in FIG.
As shown in FIG. 1, the energy-saving service provision system includes a service provision system and a payment system for electricity charges and energy-saving service charges among ESCO operators, tenant building owners, tenants, and power companies. It is a system that is established based on contractual relationships. Here, the payment system of the electricity charge and the energy saving service charge is determined by a value obtained by calculation and output by the charge calculation device 50 of the ESCO company described later.

Here, the electric power company supplies electric power to the tenant building based on a contract with the owner, and receives payment of an electricity fee corresponding to the amount of use from the owner.
The ESCO company provides energy-saving services such as installing energy-saving equipment and providing energy-saving operation management services to tenant buildings based on contracts with the owners of tenant buildings. Get paid for expenses. Examples of energy saving targets include energy saving devices / services related to electricity, gas, heat, water, and the like. The investment in energy-saving services here will continue to be provided by ESCO companies such as initial investment accompanying energy-saving renovation work and introduction of energy-saving equipment, and operation management of facilities based on specialized knowledge on energy-saving after introduction. Includes investment in services. For example, there are energy savings related to air conditioning equipment such as total heat exchangers, air conditioning control optimization, outdoor air cooling control, task ambient air conditioning control, CO ² control, and ventilation control. Other energy-saving methods include energy-saving by cogeneration, energy-saving for lighting equipment such as dimming control and introduction of high-efficiency lighting equipment, energy-saving for heat-source equipment by introducing waste heat recovery and ice heat storage systems, For example, energy saving for the transportation equipment by using an inverter or introducing a VAV low-pressure loss filter. In addition, the ESCO company receives the compensation received for the provision of energy-saving services from the costs raised by the energy-saving effect. You may not be able to receive compensation. In this case, the ESCO company will abandon the receipt of the consideration, and in order to guarantee the effect of providing the energy saving service, the ESCO company will compensate for the excess of the electricity bill before the introduction of the energy saving service.

The owner rents the tenant building based on a contract with the tenant. Moreover, the electricity bill paid to the electric power company and the ESCO cost paid to the ESCO company are collected from each tenant.
The tenant receives supply of electric power from the electric power company, receives an energy saving service from the ESCO company, and pays a price to each owner. Here, when there are a plurality of tenants in the tenant building, the consideration to be paid to each tenant is paid.

<Outline of fee structure in energy saving service provision system>
Here, the details of the electricity bill, ESCO cost, etc. are shown in FIG.
In FIG. 2, (a) shows the baseline (normalized cost) of the electricity charge before the introduction of the energy saving service providing system. (B) shows the electricity charges in the introduction contract period, which is the period from the introduction of the energy saving service providing system to the completion of the recovery of the initial investment. (C) shows an electricity bill in the re-contract period after the initial investment is collected. (D) shows an electric charge etc. in the case where the guaranteed energy saving effect is not obtained in the introduction contract period and the compensation cost by the ESCO company is generated.

  Here, the breakdown of charges during the introduction contract period shown in FIG. Electricity charges are lower than baseline electricity charges due to the benefits obtained by providing energy-saving systems. The difference between the baseline electricity charge and the electricity charge when receiving the energy saving system is the energy saving cost obtained as an energy saving effect. Of this energy saving cost, “ESCO dividend” and “necessary cost” are allocated as compensation for the energy saving service of the ESCO company. Among these, “necessary expenses” are composed of “contract fee” and “initial investment” during the introduction contract period. This “initial investment” is a predetermined amount that is repaid by dividing the expenses required for the introduction of the energy-saving service into a plurality of predetermined intervals. The “ESCO dividend” is allocated to the ESCO company as an amount of 20% with respect to the remainder obtained by subtracting the necessary cost from the energy saving cost. As a result, the difference between the sum of “electricity charges”, “contract charges”, and “initial investment” after the introduction and the baseline before the introduction of the system is the low amount of electricity charges for tenants due to the introduction of energy-saving services. It becomes the merit of the conversion.

The ESCO cost consisting of “initial investment”, “contract fee” and “ESCO dividend” here is charged according to a prorated ratio determined in advance for each tenant, and ESCO charge is calculated. The apportionment ratio here is determined according to the occupied floor area ratio in the tenant building, the equipment air conditioning functional power ratio, and the like.
Next, the breakdown of charges during the re-contract period shown in (c) will be described. Here, it is a fee payment system after paying back the entire amount of the “initial investment” by continuing to repay the cost corresponding to the “initial investment” to the ESCO company as part of the ESCO cost for each predetermined period. Here, the energy saving cost is the energy saving effect as the difference between the baseline electricity charge and the electricity charge when the energy saving service is provided, and is the same as the introduction contract period described above. However, since there is no repayment of “initial investment” during the re-contract period, the energy saving effect of the tenant is determined by subtracting the “contract fee” from the energy saving cost and subtracting 20% of the remaining amount as “ESCO dividend”. It can be lower than the burden of the introduction contract period.

  Finally, the breakdown of charges when the ESCO company's compensation costs shown in (d) occur will be described. Here, it is a special fee system when the tenant cannot obtain the energy saving effect guaranteed by the ESCO company that provides the energy saving service. Here, for example, when the energy saving effect guaranteed by the ESCO company is not obtained as a saving guarantee, the ESCO cost cannot be covered from the energy saving effect cost. In this case, the ESCO company will compensate for the cost that cannot be covered by the energy saving effect. In addition, even when the electricity bill has increased more than before the introduction of the energy saving service, the ESCO company compensates the ESCO cost and the excess electricity bill for the cost exceeding the baseline electricity bill.

<Fee structure according to fixed rate apportionment>
FIG. 3 shows an example in the case where various charges are determined by a fixed rate apportionment in the energy saving service providing system. Here, the case where the investment cost as the price of the energy saving service provided by the ESCO company is paid for every predetermined period will be described. As described above, in addition to the electricity charge, a part of the apportionment cost calculated according to the apportionment of a predetermined fixed percentage of the ESCO cost required in the tenant building is added to the tenant burden cost for each predetermined period. Here, when the ESCO cost required in the tenant building is allocated to each tenant, a certain proportion ratio determined in advance for each tenant is followed. In the example illustrated in FIG. 3, a case where three tenants, tenant A, tenant B, and tenant C participate, is taken as an example. Here, 50% is set for the tenant A, 30% for the tenant B, and 20% for the tenant C as the above-mentioned fixed proportions. Each tenant pays the owner by adding this apportioned amount to the electricity bill of each tenant, which has been reduced due to the energy saving effect. The owner pays the total electric bill of each tenant to the power company, and pays the ESCO cost to the ESCO company.

  Here, the following contract is made when the ESCO company introduces the energy saving service. In other words, as the above-mentioned baseline cost, the actual cost of electricity used in the past in the tenant building is used, and in the example shown in FIG. 3, the past result is set as 10 million yen. In this example, the ESCO company guarantees that 2 million yen will be saved by providing an energy-saving service to the tenant building (saving guarantee). As a result, a saving target of 8 million yen is set by subtracting 2 million yen of the saving guarantee from the past achievement of 10 million yen. And, as part of the 2 million yen saving guarantee guaranteed by the provision of energy-saving services, the ESCO cost of 1.2 million yen (the amount of renovation costs by the ESCO company, the provision of operation management services, and the consideration for the contract fee) Etc.) is set.

In the following, referring to FIG. 3, the examples of standard assumption cases, examples of achieving effective energy savings, and examples where energy saving targets have not yet been achieved are described according to the energy saving effect (actual results) after introduction of the energy saving service. To do.
As an example of the standard assumption case, a case will be described in which the past result of 10 million yen can be saved to 8 million yen. According to this, out of 2 million yen obtained as an energy saving effect, 1.2 million yen will be charged as ESCO expenses, and the remaining 800,000 yen will be a saving effect. This ESCO billing of 1,200,000 yen is allocated to tenant A, tenant B, and tenant C according to the above-mentioned fixed rate apportionment. Here, among ESCO expenses of 1,200,000 yen, 600,000 yen is allocated to tenant A, 360,000 yen is allocated to tenant B, and 240,000 yen is allocated to tenant C.

  Next, as an example of achieving effective energy saving, a case will be described in which a past record of 10 million yen can be reduced to a record of 7.5 million yen. According to this, the saving target of 8 million yen has been further reduced by 500,000 yen, and the energy saving effect is 2.5 million yen. Here, since the energy saving effect exceeds the saving guarantee, the ESCO cost does not change at 1.2 million yen, the saving effect increases to 1.3 million yen, and the effects of more energy saving services can be obtained.

  As an example where the energy saving target has not been achieved, a case where only 8.5 million yen has been saved compared to 10 million yen in the past will be described. According to this, the energy saving effect remains at 1.5 million yen without reaching 500,000 yen for the saving target of 8 million yen. Here, since the energy saving effect for the saving guarantee is not obtained, 500,000 yen that does not satisfy the saving guarantee out of 1,200,000 yen of the ESCO cost is compensated by the ESCO company. For this reason, the ESCO billing is 700,000 yen, and it is guaranteed that a saving effect of 800,000 yen will be secured. Here, 700,000 yen of this ESCO billing becomes the apportionable amount for each tenant, 350,000 yen for tenant A, 210,000 yen for tenant B, and 140,000 yen for tenant C, respectively. It will be.

The calculation / calculation of each charge described above is executed by the charge calculation device 50 of the ESCO company described below.
(Price calculation device)
The charge calculation device 50 calculates various charges by inputting values such as expenses by an ESCO company that has received information on electricity charges for each predetermined period from a tenant or owner.

As shown in FIG. 4, the fee calculation device 50 includes a CPU 51, a RAM 52, a ROM 53, a fee calculation program memory 54, a database memory 55, an input I / F unit 56, an output I / F unit 57, and a communication I / F unit 58. It has.
The ROM 53 stores predetermined processing data relating to processing common to each tenant in the energy saving service providing system.

Each value is temporarily stored in the RAM 52 when the fee calculation program 54P called by the CPU 51 is activated.
The database memory 55 stores data related to specifications for each tenant regarding the energy saving service. Further, as described above, the database memory 55 stores the distribution ratio data determined for each tenant. As the distribution ratio data, for example, a value determined in advance based on the occupied floor area ratio in the tenant building, the installed air conditioning functional force ratio, or the like is stored.

The input I / F unit 56 is an interface for receiving data input from the keyboard 61 and the mouse 62 and data stored in the recording medium 63. Here, for example, electricity rate data by an electric power company, apportionment ratio data for each tenant determined by a contract, and the like are accepted.
The output I / F unit 57 is an interface for connecting the display 71 and the printer 72 in order to output the various calculated expenses described above. In addition, the fee calculation device 50 can store various expenses in the recording medium 73 via the output I / F unit 57.

The communication I / F unit 58 receives data on various charges, apportionment ratio data determined by a contract, etc. from an external computer (not shown) via the network 80, or is calculated for an external computer. It is a network connection port for sending cost data etc.
The CPU 51 reads the data of the charge calculation program 54P stored in the charge calculation program memory 54, decodes the instructions in the program, and performs various processes according to the contents of the instructions. Further, the CPU 51 calls proportional distribution data, tenant-specific specification data, etc. stored in the database memory 55 as calculation control, and performs four arithmetic operations, logical operations, etc. as instructed by the fee calculation program 54P. . Further, the CPU 51 reads out data stored in the ROM 53 and the database memory 55 as data input / output control, temporarily stores data in the RAM 52 with respect to calculation results, and updates the recorded contents of the database memory 55. To do. In addition, an instruction to output the calculation result obtained by the calculation to an output device such as the display 71 or the printer 72 is given via the output I / F unit 56.

Specifically, in this CPU 51, the cost of energy saving effect described above, ESCO billing, saving effect, ESCO billing apportioned for each tenant, and the tenant burden obtained by adding up the electric bill and apportioned ESCO billing for each tenant Calculate the cost.
In this way, the ESCO company grasps the output cost of energy saving effect, ESCO billing, saving effect, ESCO billing and tenant burden cost apportioned for each tenant, Inform the charges and execute the payment system specifically. The fee calculation device 50 transmits each fee data calculated in this way to a communication terminal (not shown) owned by the owner or a communication terminal (not shown) owned by each tenant via the network 80. To send the fee information to the owner or each tenant.

<Characteristics of energy saving service providing system of this embodiment>
(1)
Generally, in a tenant building or the like, the amount of energy used is usually borne by the tenant, and the energy saving effect caused by the capital investment by the owner becomes a merit for the tenant. On the other hand, the owner may not be able to obtain the tenant's consent even if he / she tries to collect a separate amount from the tenant to meet the cost recovery required for capital investment. In this case, the owner cannot directly receive the merit of the energy saving effect, and it is difficult to recover the invested funds. It is difficult to promote capital investment.

  On the other hand, by using the charge calculation device 50 in the energy saving system providing service as in the present embodiment, the cost of energy saving effect, ESCO billing, saving effect, prorated ESCO billing for each tenant and tenant burden cost are calculated. Can do. As a result, the owner can pay an electricity fee to the electric power company and pay an ESCO cost to the ESCO company from the tenant burden cost collected from the tenant.

  As a result, the tenant can obtain the merit of paying the tenant burden cost that is lower than the baseline electricity charge without taking the risk of bearing the energy saving investment cost. In addition, the owner can cover the energy saving investment cost by part of the tenant burden cost, and there is an advantage that it is not necessary to prepare funds for initial investment. As described above, by adopting a fee structure according to the fee information output by the fee calculation device 50, it becomes possible to improve the satisfaction of the tenant and the owner. In this way, the fee structure obtained from the fee calculation device 50 allows the owner and tenant to make a mutually convinced contract through the ESCO company. It becomes possible to promote. The promotion of the introduction of energy-saving services is also an advantage for the ESCO company.

(2)
In the energy saving service providing system provided by the ESCO company, the energy saving effect is guaranteed. From this point, the owner and tenant can receive the energy saving service with peace of mind, and the introduction of the energy saving service is further promoted.
<Modification>
(A)
In the energy saving service providing system of the above-described embodiment, the owner receives the tenant burden cost that is the sum of the electricity charge and the apportioned ESCO cost for each tenant.

On the other hand, management expenses and the like due to the brokerage of the ESCO company may be collected in the form of adding to the tenant burden expenses as the owner's share. In this case as well, it is set so as not to exceed the electricity charges in the baseline of each tenant so as to ensure convincing between the owner and each tenant.
(B)
In the energy-saving service providing system of the above-described embodiment, a fee system that is calculated according to a predetermined apportionment ratio is adopted for each tenant regardless of the nature of the energy-saving service to be introduced.

  Here, among the types of energy saving services provided by the ESCO company, not all tenants can receive the same service. In other words, even energy saving services that some tenants do not wish to introduce may be introduced to the entire tenant building. In this case, depending on the type of energy saving service, the energy saving effect can be fully enjoyed. There may be a tenant that cannot be introduced (tenant that does not want to introduce) and a tenant that can fully enjoy the energy saving effect (tenant that wants to introduce). In addition, energy saving services (for example, centrally managed air-conditioning equipment, energy-saving elevators, etc.) that each tenant is forced to participate in the entire building without being able to select whether or not to introduce energy-saving services, There are energy-saving services (for example, individual remote control, etc.) that allow tenants to select desired or undesired options. In this case, there is a possibility that equality and persuasion between tenants may not be obtained.

  On the other hand, the energy-saving services provided by ESCO companies are divided into services that all tenants want to introduce and services that have tenants that do not want to be introduced. Accordingly, the tenant burden cost may be calculated by a different calculation method for each tenant to ensure equality and convincing among tenants. Specifically, for tenants who do not wish for optional services and only want joint services, in the calculation of the tenant burden cost, it is calculated excluding the optional services, and costs between both tenants who want both You may make it distinguish. In this case, the guarantee content may be different between the tenant who desires only the joint service and the tenant who desires the optional service. As the distinction of the guarantee contents, for example, for the tenant who wants only the joint service, it may be possible to raise the guarantee amount setting or raise the upper limit of the compensation amount.

For example, in the fee calculation device 50, such processing is performed by inputting information about a request for each tenant from the input I / F unit 56 and storing the information in the database memory 55. This data can be reflected in the calculation process.
In addition, as for the apportioning ratio for each tenant determined in advance and the ratio of monthly / yearly usage, different ratios may be used for each service type for various service costs constituting the ESCO cost. For example, as described above, a distribution system may be used in which the distribution ratio for each tenant in the joint service and the distribution ratio for each tenant in the arbitrary service are different. Furthermore, it is possible to apportion proportionately for each type of service, or proportionately for proportion of usage, so that the proportion for each tenant can be determined separately according to the type of service. .

<Other embodiments>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.
(A)
In the energy saving service providing system of the above embodiment, the case where the ESCO cost is apportioned at a fixed rate for each tenant has been described as an example.

However, the present invention is not limited to this. For example, as shown in FIG. 5, the ESCO cost may be apportioned according to the actual amount of energy used for each tenant.
In the example of proportional distribution shown in FIG. 5, the initial setting contract is the same as the above-described example.
Here, the example of the standard assumption case shows a case similar to the above-described example as a result, and the same result as in the case of the proportional distribution is obtained.

  Next, in the example of achieving effective energy saving, a case will be described in which the past result of 10 million yen can be reduced to 7.5 million yen as the total of the tenant results. According to this, the saving target of 8 million yen has been further reduced by 500,000 yen, and the energy saving effect is 2.5 million yen. Here, the energy saving effect exceeds the savings guarantee, but unlike the fixed rate apportionment above, the ESCO cost of 1,200,000 yen is apportioned according to the performance of each tenant A, tenant B, and tenant C, and the burden on each tenant You will be charged for the cost.

In the example where the energy saving target has not been achieved, the energy saving effect of the savings guarantee is not obtained as in the case of the above-mentioned fixed rate apportionment. To be compensated. And the 700,000 yen ESCO billing that subtracted the compensation amount will be apportioned according to the performance of each tenant.
Thus, by apportioning according to the results, it becomes possible to improve energy saving awareness for each tenant.

(B)
Further, for example, as shown in FIG. 6, the ESCO cost may be apportioned according to the energy saving effect for each tenant. The past results for each tenant here are input by the input I / F unit 56 and the like, and are stored in the database memory 55 so that they can be referred to in the execution of the fee calculation program 54P.

In the example of proportional distribution shown in FIG. 6, the initial setting contract is the same as the above-described example.
Here, the example of the standard assumption case shows a case similar to the above-described example as a result, and the same result as in the case of the proportional distribution is obtained.
Next, in an example of achieving effective energy saving, a case where the past result of 10 million yen can be reduced to 7.5 million yen and the energy saving effect is 2.5 million yen will be described. Here, out of the 2.5 million yen of this energy saving effect, the energy saving effect by tenant A is 1.3 million yen (5 million yen-3.7 million yen), and the energy saving effect by tenant B is 700,000 yen (3 million yen- 2.3 million yen), and the energy saving effect by tenant C is 500,000 yen (2 million yen-1.5 million yen). As a result, the ESCO cost of 1,200,000 yen will be apportioned according to the ratio of the energy saving effect for each tenant.

  In the example where the energy saving target has not been achieved, the energy saving effect of the savings guarantee is not obtained as in the case of the above-mentioned fixed rate apportionment. To be compensated. Then, the ESCO charge of 700,000 yen obtained by subtracting the compensation amount is apportioned according to the ratio of the energy saving effect for each tenant, as in the above example of achieving effective energy saving.

In this way, by allocating according to the energy saving effect compared with the past results, the tenant with more energy consumption can improve the energy saving awareness.
(C)
In addition, for example, as shown in FIG. 7, an individual contract may be made by concluding a contract with an ESCO company for each tenant and setting a saving cost, an ESCO cost apportionment, etc. for each tenant. .

Here, the example of the standard assumption case shows a case similar to the above-described example as the results of each tenant, and the same result as that obtained by the proportional distribution is obtained.
Next, in the example of achieving effective energy saving, for example, for Tenant A, an energy saving effect of 1.3 million yen, which is higher than the energy saving guarantee of 1 million yen, is obtained, which is 300,000 compared to the case of the standard assumption case. The saving effect is added by the yen. In addition, here, the energy saving effect reflects only the energy saving effect of each tenant, regardless of the effect of the entire tenant building.

In an example where the energy saving target is not achieved, if the energy saving effect is less than the savings guarantee, the ESCO fee is calculated by subtracting that amount from the ESCO cost. Here, the deducted cost is a guarantee cost of the ESCO company.
For example, there may be a case where Tenant A has effectively achieved energy savings and Tenant B has not achieved the target energy savings. Will be charged.

In this way, each tenant individually makes a contract with the ESCO company, thereby making it possible to make a highly flexible contract that reflects various circumstances for each tenant that is not influenced by other tenants.
(D)
In the energy saving service providing system of the above embodiment, the ESCO company adopts the absolute value of the energy usage as a criterion for determining whether or not the energy saving effect corresponding to the saving guarantee is obtained.

  However, the present invention is not limited to this, and for example, it may be determined whether or not the saving is guaranteed based on a time average obtained by dividing the total energy usage by the total usage time. Alternatively, the total use time may be used as a reference. Furthermore, a value obtained by a predetermined function represented by a time average and a total use time may be used as a reference. Rather than adopting these criteria, it is possible to avoid an unauthorized increase in energy usage due to the energy saving guarantee provided by the ESCO company.

(E)
In the energy saving service providing system of the above-described embodiment, the fee calculation device 50 is owned by the ESCO company, and receives information such as an electricity bill for each predetermined period from the tenant or owner, and calculates each expense.
However, the present invention is not limited to this. For example, the fee calculation device 50 may be owned by the owner or each tenant. In this case, each tenant grasps the billing cost of the electricity bill for each predetermined period from the power company, and each tenant inputs this information into the charge calculation device 50, or the information on the electricity bill from each tenant. Each cost may be calculated by the owner receiving the notification.

  The charge calculation device 50 may receive the information on the electricity charge from the electric power company via the network 80, and automatically perform the above-described calculation using the reception of this information as a trigger.

  According to the present invention, capital investment for obtaining an energy saving effect can be promoted, so that it is particularly useful when a predetermined cost is required by introducing an energy saving device / service to the facility.
