[Figure 7] It is a diagram showing an example of the hardware configuration. 【Mode for Carrying Out the Invention】 【0018】 Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the invention according to the claims. Also, not all combinations of features described in the embodiments are essential for the solution means of the invention. 【0019】 In recent years, in order to suppress global warming and realize a low-carbon and decarbonized society, efforts to reduce greenhouse gases such as CO2 are being emphasized not only among countries but also among companies around the world. Renewable energy that does not generate CO2, such as solar power generation, is considered to have "environmental value", and this environmental value is certificated and traded in the market. Therefore, the demand for using renewable energy generated by power generation devices such as solar power generation facilities installed in facilities as environmental value is increasing. 【0020】 Currently, in order to prove environmental value, applications are made to regulatory authorities such as FIT non-fossil certificates and non-FIT non-fossil certificates, the J credit system, and green power certificates for certification. However, a method for calculating in advance the environmental value of renewable energy generated by power generation devices such as solar power generation facilities installed in facilities and distributing it between the building owner and the occupants living in the building is not known. 【0021】 Therefore, in the present embodiment, a system is provided that distributes the environmental value of renewable energy generated by power generation equipment installed in a facility between the building owner and the occupants living in the building. 【0022】 FIG. 1 shows an example of the overall configuration of a system to which an environmental value determination device 100 according to the present embodiment is applied. The system includes a power generation facility 10, a power conditioner 200, a main switchboard 300, a sub-switchboard 62, a load 66, a buyout meter 82, a power selling meter 84, and an environmental value determination device 100. The environmental value determination device 100 acquires and derives environmental values and determines the amounts of environmental values distributed to the owner or operator of the facility 50 and the occupants 60. 【0023】 The power generation facility 10 is a solar power generation facility installed on the rooftop or the like by the owner or operator of the facility 50. The power generation facility 10 may be a power generation facility that uses renewable energy such as wind power or geothermal energy other than sunlight. The facility 50 is a structure or building that can be used by a contracted natural person or legal entity, such as a building, a commercial facility, or an apartment building. The occupants 60 are natural persons or legal entities that have contracted to use the facility 50. 【0024】 The power conditioner 200 converts the DC power generated by the power generation facility 10 into AC power. The power conditioner 200 has a power generation amount measuring device 20. The power generation amount measuring device 20 measures the power generation amount by the power generation facility 10. The power generation amount measuring device 20 may be a smart meter. 【0025】 The main switchboard 300 and a plurality of sub-switchboards 62 are installed in the facility 50. The sub-switchboard 62 may be installed in the living space of each occupant 60. The main switchboard 300 distributes the power from the grid 500 and the power from the power generation facility 10 to each sub-switchboard 62. A load 66 is connected to the sub-switchboard 62. The load 66 is an electrical device that consumes power. The electrical device may be arranged within the living space of the occupant 60. The electrical device includes an air conditioning device, a lighting device, and an electronic device. The sub-switchboard 62 has a power meter 64. The power meter 64 measures the amount of power consumed by the load 66. 【0026】 The purchase meter 82 and the power sales meter 84 are connected to the service drop between the main distribution board 300 and the grid 500. The purchase meter 82 measures the amount of electricity supplied from the grid 500. That is, the purchase meter 82 measures the amount of electricity purchased from the power company. The power sales meter 84 measures the amount of electricity generated by the power generation equipment 10 that is returned to the grid 500. That is, the power sales meter 84 measures the amount of surplus electricity (reverse power flow) generated by the power generation equipment 10 that is sold to the power company. Smart meters may be installed instead of the purchase meter 82 and the power sales meter 84. The purchase meter 82, the power sales meter 84, the power generation meter 20, and the power meter 64 are wirelessly or wired to communicate with the environmental value determination device 100. 【0027】 Figure 2 shows a functional block diagram of the environmental value determination device 100 shown in Figure 1. The environmental value determination device 100 includes an acquisition unit 102, an extraction unit 104, a determination unit 106, a registration unit 108, a reception unit 110, a notification unit 112, and a storage unit 120. If the environmental value determination device 100 is a computer equipped with a processor, the processor may function as the acquisition unit 102, the extraction unit 104, the determination unit 106, the registration unit 108, the reception unit 110, and the notification unit 112. 【0028】 The acquisition unit 102 acquires the amount of electricity generated by the power generation equipment 10. The acquisition unit 102 may acquire the measured value as the amount of electricity generated by the power generation meter 20 installed on the power conditioner 200. The power generation meter 20 may be installed between the power conditioner 200 and the main distribution board 300. The power generation meter 20 may be installed on the main distribution board 300. In this respect, this embodiment is not particularly limited. 【0029】 The derivation unit 104 derives a first environmental value based on the amount of power generated. The first environmental value may be a value equivalent to an environmental value certificate that certifies the environmental value held by renewable energy. Examples of environmental value certificates that certify the environmental value held by renewable energy include J-Credits, green power certificates, or non-fossil fuel certificates. 【0030】 J-Credits are a system in which the government certifies the amount of greenhouse gas emissions reduced or absorbed through initiatives such as energy-saving equipment, the introduction of renewable energy, and forest management, as "credits." Green electricity certificates are certificates that certify the environmental value of electricity generated from renewable energy sources, and are issued by certificate issuing companies with the approval of a third-party approval body. Examples of overseas credits include GO (Guarantee of Origin) in Europe, REC (Renewable Energy Certificate) in North America, and I-REC (International Renewable Energy Certificate) in other regions. 【0031】 Non-fossil fuel certificates are certificates that extract and certify the non-fossil value of electricity generated from non-fossil fuel sources that do not use fossil fuels such as oil or coal, and are traded on the non-fossil fuel value trading market. Non-fossil fuel certificates include non-FIT non-fossil fuel certificates and FIT non-fossil fuel certificates. 【0032】 If all the electricity generated by the power generation equipment 10 is consumed by the facility 50, that is, if all the electricity generated by the power generation equipment 10 is consumed internally, the derivation unit 104 may derive, for example, the amount of J-Credit certification granted to the amount of renewable energy electricity as the first environmental value. The derivation unit 104 may derive the amount of CO2 emissions (t-CO2) obtained by multiplying the amount of renewable energy electricity (thousand kWh) by a predetermined coefficient (t-CO2 / thousand kWh) as the first environmental value. The predetermined coefficient may be determined according to the CO2 emission coefficient of the power company contracted by the owner of the facility 50. Alternatively, the derivation unit 104 may derive the first environmental value corresponding to the electricity generated by the power generation equipment 10 according to a learning model that has been trained using, for example, past J-Credit application data, which includes combinations of introduction conditions for power generation equipment that generates electricity using renewable energy (region, solar panel installation area, etc.) and the environmental value granted for those introduction conditions, as training data. Furthermore, the derivation unit 104 may derive the first environmental value as the environmental value obtained based on the application proposal, which includes the measurement means and implementation plan submitted in accordance with the methodology of each certification system. This environmental value may be obtained before or after the installation of the power generation equipment 10. 【0033】 If all the electricity generated by the power generation equipment 10 is being fed back, the derivation unit 104 may derive an environmental value equivalent to a non-fossil fuel certificate as the first environmental value. The derivation unit 104 may derive the CO2 emissions (t-CO2) obtained by multiplying the amount of renewable energy electricity (thousand kWh) by a predetermined coefficient equivalent to a non-fossil fuel certificate (t-CO2 / thousand kWh) as the first environmental value. 【0034】 The determination unit 106 determines the amount of environmental value to be distributed from the first environmental value to each of the multiple target persons, which are the owner or operator of the facility 50 and the residents 60 who occupy the facility 50, in a ratio predetermined for each of the multiple target persons. The predetermined ratio may be proportional to the amount of electricity consumed by each of the multiple target persons. The registration unit 108 registers the amount of environmental value distributed to each of the multiple target persons in the storage unit 120, associating it with each of the multiple target persons. 【0035】 The reception unit 110 receives the desired amount of environmental value from each of the multiple subjects. The registration unit 108 registers the desired amount of environmental value from each of the multiple subjects received by the reception unit 110 in the storage unit 120, associating it with each of the multiple subjects. If there is a subject among the multiple subjects whose allocated amount of environmental value determined by the determination unit 106 is less than their desired amount of environmental value, the notification unit 112 notifies that subject with a message indicating that their allocated amount of environmental value is less than their desired amount. For example, the notification unit 112 may notify the subject by sending an email message to them. Alternatively, if the subject has installed the environmental value allocation application according to this embodiment on a mobile device such as a smartphone, the notification unit 112 may notify the subject by sending a notification message within the application. 【0036】 Furthermore, the acquisition unit 102 also acquires a first consumption amount, which is consumed by multiple individuals, and a second consumption amount, which is consumed by the reverse power flow of the power generation equipment 10, from the total amount of power generated. Here, the first consumption amount is the sum of the amounts consumed by each of the multiple individuals from the amount of power generated by the power generation equipment 10, i.e., the sum of the amounts consumed by each individual for their own consumption. The second consumption amount is the amount consumed by the reverse power flow. The acquisition unit 102 may, for example, acquire the amount of electricity sold measured by the electricity sales meter 84 as the second consumption amount. The acquisition unit 102 may, for example, acquire the difference in consumption amount obtained by subtracting the second consumption amount from the amount of power generated as the first consumption amount. 【0037】 The derivation unit 104 further derives a second environmental value based on the first consumption and a third environmental value based on the second consumption. The second and third environmental values, like the first environmental value, are values equivalent to environmental value certificates that certify the environmental value possessed by renewable energy. 【0038】 The second environmental value is the environmental value equivalent to the amount of electricity consumed by self-consumption of renewable energy. The second environmental value is the value of the amount of renewable energy electricity consumed self-consumption that can be certified as environmental value, and may be, for example, J-Credits, green electricity certificates, or a value equivalent to overseas credits. 【0039】 The derivation unit 104 may derive a second environmental value by multiplying the first consumption by a coefficient (t-CO2 / thousand kWh) equivalent to J-Credits, green power certificates, or overseas credits. The derivation unit 104 may, for example, derive a second environmental value corresponding to the electricity generated by the power generation facility 10 according to a learning model that has been trained using combinations of introduction conditions for power generation facilities that generate electricity using renewable energy (region, solar panel installation area, etc.) and the environmental value or coefficient assigned to those introduction conditions as training data from past J-Credit application data. 【0040】 The third environmental value is the environmental value corresponding to the amount of electricity generated by the power generation facility 10 that uses renewable energy, excluding the amount used for self-consumption, i.e., the amount of electricity that is reverse-flowed. The third environmental value is the value of the amount of renewable energy electricity other than that used for self-consumption that can be certified as environmental value, and may be a value equivalent to non-fossil fuel certificates such as non-FIT non-fossil fuel certificates or FIT non-fossil fuel certificates. The third environmental value may also include the environmental value corresponding to the amount of electricity other than that used for self-consumption that is not reverse-flowed and is used for other purposes. For example, the third environmental value may include a value equivalent to J-credits, green power certificates, or overseas credits obtained in relation to the storage and extraction of hydrogen produced by electrolyzing water using electricity other than that used for self-consumption, and power generation using fuel cells, etc. 【0041】 The derivation unit 104 may derive the third environmental value by multiplying the second consumption amount by a coefficient (t-CO2 / thousand kWh) equivalent to that of non-fossil fuel certificates, such as non-FIT non-fossil fuel certificates and FIT non-fossil fuel certificates. Alternatively, the derivation unit 104 may derive the third environmental value as the environmental value obtained by other means of certifying the environmental value of the reverse power flow of electricity generated by the power generation facility 10. 【0042】 Furthermore, the determination unit 106 determines the amount of environmental value to be distributed to each of the multiple subjects based on the first environmental value, using a ratio predetermined for each of the multiple subjects. The determination unit 106 may determine the amount of environmental value to be distributed to each of the multiple subjects so that the first environmental value, which is the sum of the second and third environmental values, is distributed to each of the multiple subjects using a ratio predetermined for each of the multiple subjects. 【0043】 In this embodiment, the determination unit 106 has been described as determining the amount of environmental value to be distributed to each of the multiple target persons from the first environmental value, based on a ratio predetermined for each target person. In contrast, the determination unit 106 may determine the amount of environmental value to be distributed to each of the multiple target persons by allocating a certain amount of the first environmental value entirely to the owner of the facility 50, and distributing the remaining first environmental value to each of the residents in a ratio predetermined for each resident. 【0044】 The pre-assigned ratio may be proportional to the floor area of each resident. Alternatively, the pre-assigned ratio may be proportional to the amount of electricity consumed by each resident during a predetermined time period in the daytime when solar power generation can be performed efficiently. 【0045】 Figure 3 is a flowchart showing an example of the procedure for determining the amount of environmental value to be allocated according to this embodiment. 【0046】 The acquisition unit 102 acquires the amount of electricity generated by the power generation equipment 10, i.e., the amount of electricity generated (S100). The acquisition unit 102 acquires the amount of electricity consumed by tenants W1 and the amount of electricity consumed by non-tenants W2 from the electricity of the power generation equipment 10 (S102). Tenants refer to the multiple occupants 60 mentioned above. The amount of electricity consumed by tenants W1 corresponds to the first consumption, i.e., the amount consumed by the tenants themselves. The amount of electricity consumed by non-tenants W2 corresponds to the second consumption, i.e., the amount of electricity flowed in the reverse direction. 【0047】 The derivation unit 104 derives a second environmental value based on the consumption amount W1 and a third environmental value based on the consumption amount W2 (S104). The derivation unit 104 derives a first environmental value of the power generation equipment 10 based on the second and third environmental values (S106). The derivation unit 104 may derive a first environmental value by adding the second and third environmental values together. 【0048】 The decision unit 106 determines the amount of the first environmental value to be distributed to each of the multiple subjects (S108). The decision unit 106 may determine the amount of the first environmental value to be distributed to each of the multiple subjects based on a ratio that has been pre-assigned to each of the multiple subjects. The pre-assigned ratio may be proportional to the amount of electricity consumed by each of the multiple subjects' power generation facilities 10. 【0049】 The registration unit 108 registers the amount of the first environmental value allocated to each of the multiple subjects in the storage unit 120, in association with each of the subjects (S110). 【0050】 Through the above process, the environmental value of renewable energy generated by the power generation equipment 10 installed in facility 50 can be distributed between the building owner and the residents of the building. 【0051】 Figure 4 is a flowchart illustrating an example of a procedure that may be performed in addition to the flow shown in Figure 3, for notifying the relevant individuals that the amount of environmental value allocated is less than the desired amount of environmental value. 【0052】 The reception unit 110 receives the desired amount of environmental value from each participant. The notification unit 112 determines whether there are any participants whose allocated amount of environmental value is less than the requested amount received. For example, the notification unit 112 makes this determination by comparing the allocated amount of the first environmental value registered in association with each participant in S110 of Figure 3 with the requested amount received in S200. 【0053】 If there are recipients whose allocation of environmental value is less than their desired amount, the notification unit 112 will notify those recipients that their allocation of environmental value is less than their desired amount. This allows recipients who receive the notification to take other measures to compensate for the shortfall in environmental value. 【0054】 In the above embodiment, an example was described in which the power generation equipment 10 is installed in a facility owned by the owner or operated by the operator. However, the environmental value determination device 100 can also be applied in the form of a so-called off-site PPA, in which the power generation equipment 10 is installed on land or a building contracted by the contractor. For example, if the owner of a building installs solar panels on land in a remote location far from the building, the environmental value determination device 100 may determine the amount of environmental value to be distributed to the owner and the tenants of the building in order to distribute the environmental value of the electricity generated by the solar panels between the owner and the tenants of the building. 【0055】 Figure 5 shows an example of the overall configuration of a system to which an environmental value determination device 100 according to another embodiment is applied. The system shown in Figure 5 differs from the system shown in Figure 1 in that it includes a power generation equipment management device 400 and the power generation equipment 10 is installed outside the facility 50. 【0056】 The power generation equipment management device 400 manages the power generation equipment 10. The power generation equipment management device 400 may acquire the amount of electricity generated by the power generation equipment 10 via a smart meter installed in the power generation equipment 10. The power generation equipment management device 400 provides the amount of electricity generated by the power generation equipment 10 to the environmental value determination device 100. The power generation equipment 10 is installed on land or in a building contracted by the contractor and generates electricity using renewable energy. The power generation equipment 10 may be a solar power generation facility that generates electricity using solar panels. 【0057】 The acquisition unit 102 acquires the amount of electricity generated by the power generation equipment 10 from the power generation equipment management device 400. The acquisition unit 102 may also acquire the amount of electricity generated by the power generation equipment 10 directly from a smart meter installed on the power generation equipment 10. The derivation unit 104 derives the first environmental value based on the amount of electricity generated. The derivation unit 104 may derive the first environmental value by multiplying the amount of electricity generated by a coefficient (t-CO2 / thousand kWh) equivalent to that of non-fossil fuel certificates such as non-FIT non-fossil fuel certificates and FIT non-fossil fuel certificates. 【0058】 The determination unit 106 determines, from the first environmental value, the amount of environmental value to be distributed to each of the multiple target persons, who are the contractor and the tenants who occupy the facilities owned or operated by the contractor, in proportion to a ratio predetermined for each of the multiple target persons. The registration unit 108 registers the amount of environmental value to be distributed to each of the multiple target persons in the storage unit 120, associating it with each of the multiple target persons. The predetermined ratio may be proportional to the amount of electricity consumed by each of the multiple target persons' power generation facilities 10. The predetermined ratio may be proportional to the floor area of the tenants. The predetermined ratio may be proportional to the amount of electricity consumed by each tenant during a predetermined time period in the daytime when solar power generation can be performed efficiently. 【0059】 Figure 6 is a flowchart showing an example of a procedure for determining the distribution amount of environmental value according to another embodiment. 【0060】 The acquisition unit 102 acquires the amount of electricity generated by the power generation equipment 10 from the power generation equipment management device 400 (S300). The derivation unit 104 derives the first environmental value by multiplying the amount of electricity generated by a predetermined coefficient (S302). The determination unit 106 determines from the first environmental value the amount of environmental value to be distributed to each of the multiple target persons, who are the contractor and the occupants of the facilities owned or operated by the contractor, at a ratio predetermined for each of the multiple target persons (S304). The registration unit 108 registers the amount of environmental value to be distributed to each of the multiple target persons in the storage unit 120, associating it with each of the multiple target persons (S306). 【0061】 As described above, according to the environmental value determination device 100 of another embodiment, in the form of an off-site PPA, for example, the environmental value of electricity generated by solar panels installed on another person's land in a remote location away from the building can be distributed between the building owner and the tenants occupying the building. 【0062】 Figure 7 shows an example of a computer 1200 in which multiple aspects of the present invention may be embodied in whole or in part. A program installed on the computer 1200 can cause the computer 1200 to function as an operation associated with an apparatus according to an embodiment of the present invention, or as one or more "parts" of said apparatus. Alternatively, the program can cause the computer 1200 to execute said operation or said one or more "parts". The program can cause the computer 1200 to execute a process or a stage of said process according to an embodiment of the present invention. Such a program may be executed by the CPU 1212 to cause the computer 1200 to execute a particular operation associated with some or all of the blocks in the flowcharts and block diagrams described herein. 【0063】 The computer 1200 according to this embodiment includes a CPU 1212 and RAM 1214, which are interconnected by a host controller 1210. The computer 1200 also includes a communication interface 1222 and input / output units, which are connected to the host controller 1210 via an input / output controller 1220. The computer 1200 also includes a ROM 1230. The CPU 1212 operates according to programs stored in the ROM 1230 and RAM 1214, thereby controlling each unit. 【0064】 The communication interface 1222 communicates with other electronic devices via a network. A hard disk drive may store programs and data used by the CPU 1212 in the computer 1200. The ROM 1230 stores boot programs and / or programs that depend on the computer 1200's hardware, such as a boot program executed by the computer 1200 upon activation. Programs are provided via computer-readable recording media such as a CR-ROM, USB memory, or IC card, or via a network. Programs are installed in RAM 1214, which is also an example of a computer-readable recording media, or in ROM 1230, and executed by the CPU 1212. The information processing described within these programs is read by the computer 1200, resulting in coordination between the programs and the various types of hardware resources described above. An apparatus or method may be configured to implement information operations or processing in accordance with the use of the computer 1200. 【0065】 For example, when communication is performed between a computer 1200 and an external device, the CPU 1212 may execute a communication program loaded into RAM 1214 and, based on the processing described in the communication program, instruct the communication interface 1222 to perform communication processing. Under the control of the CPU 1212, the communication interface 1222 reads the transmission data stored in the transmission buffer area provided in RAM 1214 or a recording medium such as a USB memory, sends the read transmission data to the network, or writes the received data received from the network to a receive buffer area or the like provided on the recording medium. 【0066】 Furthermore, the CPU 1212 may read all or necessary parts of a file or database stored on an external storage medium such as a USB memory stick into the RAM 1214, and perform various types of processing on the data in the RAM 1214. The CPU 1212 may then write the processed data back to the external storage medium. 【0067】 Various types of information, such as various types of programs, data, tables, and databases, may be stored on the recording medium and subjected to information processing. The CPU 1212 may perform various types of processing on the data read from RAM 1214, including various types of operations, information processing, conditional judgments, conditional branching, unconditional branching, information retrieval / replacement, etc., as described throughout this disclosure and specified by the program instruction sequence, and write the results back to RAM 1214. The CPU 1212 may also retrieve information in files, databases, etc., within the recording medium. For example, if multiple entries are stored in the recording medium, each having an attribute value of a first attribute associated with an attribute value of a second attribute, the CPU 1212 may search among the multiple entries for an entry that matches the condition for which the attribute value of the first attribute is specified, read the attribute value of the second attribute stored in that entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition. 【0068】 The program or software module described above may be stored on or near computer 1200 on a computer-readable storage medium. Alternatively, a recording medium such as a hard disk or RAM provided within a server system connected to a dedicated communication network or the Internet can be used as a computer-readable storage medium, thereby providing the program to computer 1200 via the network. 【0069】 Computer-readable media may include any tangible device capable of storing instructions that can be executed by a suitable device.
