Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, organizations in enterprises are scattered in various regions such as branches and factories. Patent Document 1 does not consider accurately grasping the CO2 emissions related to these scattered organizations.

[0006] The present invention has been made in view of the problems of the above prior art, and an object thereof is to provide an electric power amount management system that can simply and accurately manage CO2 emissions in an organizational structure scattered in various places.

Means for Solving the Problems

[0007] In order to solve the above problems, the present invention is an electric power amount management system for managing an electric power amount, The aforementioned power consumption management system comprises a storage unit, an acquisition unit, and a calculation unit. The memory unit stores a hierarchical structure indicating the dependency relationships of multiple locations, and conversion information for converting the amount of electricity for each electricity classification under predetermined conditions into CO2 emissions. The acquisition unit acquires the power classification and the amount of power for each power classification at each location, and stores them in the storage unit in correspondence with the hierarchical structure. The calculation unit calculates the CO2 emissions within a specific dependency range specified by the user in the hierarchical structure, based on the amount of electricity associated with the hierarchical structure and the conversion information.

[0008] Furthermore, the present invention relates to a power management method executed by a power management system for managing power consumption, The aforementioned power consumption management system comprises a storage unit, an acquisition unit, and a calculation unit. The memory unit stores a hierarchical structure indicating the dependency relationships of multiple locations, and conversion information for converting the amount of electricity for each electricity classification under predetermined conditions into CO2 emissions. The acquisition unit acquires the power classification and the amount of power for each power classification at each location, and stores them in the storage unit in correspondence with the hierarchical structure. The calculation unit includes the step of calculating CO2 emissions within a specific dependency range designated by the user in the hierarchical structure, based on the amount of electricity associated with the hierarchical structure and the conversion information.

[0009] Furthermore, the present invention relates to an energy management program for managing energy consumption, The computer functions as a storage unit, an acquisition unit, and a calculation unit. The memory unit stores a hierarchical structure indicating the dependency relationships of multiple locations, and conversion information for converting the amount of electricity for each electricity classification under predetermined conditions into CO2 emissions. The acquisition unit acquires the power classification and the amount of power for each power classification at each location, and stores them in the storage unit in correspondence with the hierarchical structure. The calculation unit calculates the CO2 emissions within a specific dependency range specified by the user in the hierarchical structure, based on the amount of electricity associated with the hierarchical structure and the conversion information.

[0010] This configuration allows for easy and accurate management of CO2 emissions across scattered organizational structures. For example, an organization can manage CO2 emissions by focusing on a specific range (specific dependent range) designated by the user as needed.

[0011] In a preferred embodiment of the present invention, the power classification includes a power plan defined for each power supplier. The calculation unit calculates the CO2 emissions within the specified dependent range based on conversion information that includes the CO2 conversion coefficient for each electricity plan.

[0012] This configuration allows for the accurate calculation of CO2 emissions for each electricity plan within a specific dependency scope. As a result, users such as administrators within an organization can accurately understand the CO2 emissions related to the organization's hierarchical structure.

[0013] In a preferred embodiment of the present invention, the calculation unit calculates the CO2 emissions for a specific power classification within the specified dependency range, based on the power classification specified by the user.

[0014] This configuration makes it possible to calculate CO2 emissions for specific electricity plans or electricity classifications based on predetermined conditions. For example, it is possible to identify locations within multiple branches under the jurisdiction of the head office, or business sites under the jurisdiction of branches, that are contracted under a particular electricity plan, and then calculate their CO2 emissions.

[0015] In a preferred embodiment of the present invention, the calculation unit calculates the CO2 emissions for a specific power type within the specified dependency range, based on the power type specified by the user.

[0016] By adopting such a configuration, it is possible to calculate the CO2 emissions for a specific power type. For example, in a certain branch office and the business sites under the jurisdiction of the branch office, it is possible to selectively calculate the CO2 emissions for the power consumption of three-phase 200V.

[0017] In a preferred form of the present invention, the power consumption management system further includes a display processing unit. Based on the calculation result by the calculation unit, the display processing unit performs display processing on the CO2 emissions of the specific subordinate range and the CO2 emissions for each location constituting the specific subordinate range, and transmits the display processing result.

[0018] By adopting such a configuration, it is possible to quickly check on the same screen the CO2 emissions of the specific subordinate range and the CO2 emissions for each location belonging to this range.

[0019] In a preferred form of the present invention, the power consumption management system further includes a display processing unit. The power classification includes power types determined according to the supply conditions of the voltage. Based on the calculation result by the calculation unit, the display processing unit performs display processing on the breakdown of the power types in the CO2 emissions of the specific subordinate range, and transmits the display processing result.

[0020] By adopting such a configuration, the user can easily and accurately check the breakdown of the power types. For example, the user can easily and accurately check the CO2 emissions of single-phase three-wire 200V, single-phase two-wire 100V (lighting), and three-phase three-wire 200V (power), etc. in a certain subordinate range.

[0021] In a preferred form of the present invention, the power consumption management system further includes a display processing unit. Based on the calculation result by the calculation unit, the display processing unit performs display processing on the CO2 emissions at the location of the selected layer in the hierarchical structure, and transmits the display processing result.

[0022] This configuration allows users to compare and view the CO2 emissions of multiple locations (e.g., branch A and branch B) belonging to a specific hierarchical level (e.g., branch hierarchy).

[0023] In a preferred embodiment of the present invention, the power consumption management system further comprises a specific processing unit, The acquisition unit acquires contract information relating to electricity contracts for supplying power to each location, stores it in the storage unit in association with the hierarchical structure, The specific processing unit identifies the number of electricity contracts within the specified dependent scope and the usage status of said electricity contracts based on the contract information.

[0024] This configuration makes it easy to identify the number of electricity contracts and usage patterns at businesses and construction sites where usage can change almost every month. [Effects of the Invention]

[0027] Further details will be provided below with reference to the attached drawings. The drawings show preferred embodiments. However, many different forms are possible and the embodiments are not limited to those described herein.

[0028] For example, in this embodiment, the configuration and operation of the power management system will be described, but similar effects can be achieved by the execution method (steps), device, computer program, etc. The program in this embodiment may be provided as a non-transient recording medium that can be read by a computer, or it may be provided so that it can be downloaded from an external server.

[0030] In this embodiment, "information" can be represented, for example, by the physical value of a signal value representing voltage or current, the high or low value of a signal value as a set of binary bits consisting of 0s or 1s, or by a quantum superposition (so-called qubit), and communication and calculations can be performed on a circuit in a broad sense.

[0031] In a broad sense, a circuit is a circuit realized by appropriately combining circuits, circuits (including processors and memory). That is, it includes CPUs (Central Processing Units), GPUs (Graphics Processing Units), LSIs (Large Scale Integration), ASICs (Application Specific Integrated Circuits), FPGAs (Field-Programmable Gate Arrays), etc.

[0032] <System Configuration> Figure 1 is a block diagram showing the system configuration according to one embodiment of the present invention. As shown in Figure 1, the power consumption management system 1 includes an information processing device 10 and a database DB. The power consumption management system 1 is configured to communicate with a plurality of user terminals 2 (reference numerals 2(a) to 2(c) in Figure 1) and various power DBs 3 (reference numerals 3(a) to 3(c)) via a network NW. For example, in this system, user terminals 2 can also communicate with various power DBs 3 via the information processing device 10.

[0033] The information processing device 10 operates as a server, the user terminal 2 is a terminal used by administrators of companies and organizations to view CO2 emissions, etc., and the power DB 3 (power management organization DB 3(a), demand company power DB (b), electric utility DB (c)) is a database in which the information processing device 10 acquires power consumption data from companies and organizations. In this specification, companies and organizations that use electricity are referred to as demand companies.

[0034] In this embodiment, the network NW is an IP (Internet Protocol) network, but there are no restrictions on the type of communication protocol, nor on the type or size of the network.

[0035] Furthermore, a general-purpose server computer or personal computer can be used as the information processing device 10. It is also possible to implement the functional components described later on multiple computers to configure the power management system 1.

[0036] User terminal 2 is a terminal used by electricity-consuming companies (and their management personnel). User terminal 2 can be a smartphone, tablet, personal computer, wearable device, etc. User terminal 2 stores a user-specific electricity usage management application program, which includes functions for users to view electricity usage, CO2 emissions, etc.

[0037] Power DB3 is a database for managing the electricity usage of consumer companies. A tablet device, personal computer, etc., can be used as Power DB3. Power DB3 is configured to store a power usage management application program and to send the consumer companies' electricity usage data to the information processing device 10.

[0038] Furthermore, user terminal 2 and power DB3 can be configured without their respective power management application programs. In this case, user terminal 2 and power DB3 can view and transmit information via a web browser or similar (or through data acquisition from information processing device 10).

[0039] <Hardware Configuration> Figure 2(a) shows an example of the hardware configuration of the information processing device 10. The information processing device 10 comprises a control unit 11, a storage unit 12, and a communication unit 13 as its hardware configuration.

[0040] The control unit 11 includes one or more processors such as a CPU, and controls the entire operation of the information processing device 10 by executing the power management program, OS, and other applications according to the present invention.

[0041] The storage unit 12 is an HDD, SSD, ROM, RAM, etc., and stores the power consumption management program according to the present invention and data used by the control unit 11 when executing processing based on the program. The control unit 11 executes processing based on the power consumption management program stored in the storage unit 12, thereby realizing the functional configuration described later.

[0042] The communication unit 13 performs communication control with the network NW and provides inputs necessary for operating the information processing device 10, as well as outputs related to the operation results.

[0043] Figure 2(b) shows an example of the hardware configuration of terminal 90 (user terminal 2 in Figure 1). Terminal 90 comprises a control unit 91, a storage unit 92, a communication unit 93, an input unit 94, and an output unit 95 as its hardware configuration.

[0044] The control unit 91 of the terminal 90 includes one or more processors such as a CPU and controls the entire operation of the terminal 90. The storage unit 92 of the terminal 90 is an HDD, SSD, ROM, RAM, etc., and stores the power consumption management application program mentioned above, as well as data used by the control unit 91 when it executes processing based on the program.

[0045] The communication unit 93 of terminal 90 controls communication with the network. The input unit 94 of terminal 90 is a touch panel, mouse, keyboard, etc., which inputs user operation requests to the control unit 91. The output unit 95 of terminal 90 is a display, etc., which displays the results of processing by the control unit 91.

[0046] <Functional Configuration> As shown in Figure 2(a), the information processing device 10 comprises, as a functional configuration, an acquisition unit 101, a calculation unit 102, a specific processing unit 103, and a display processing unit 104. These represent the concrete realization of information processing performed by software (stored in the storage unit 12) by hardware (control unit 11, etc.).

[0047] The acquisition unit 101 acquires (receives) various information from user terminals, power DB3, etc. The acquisition unit 101 acquires user information and company information. In this embodiment, the acquisition unit 101 acquires the power classification and the amount of power for each power classification at each location and stores it in the storage unit 12 in association with a hierarchical structure. The acquisition unit 101 also acquires hierarchical structure information and conversion information and stores it in the storage unit 12.

[0048] The calculation unit 102 calculates CO2 emissions. In this embodiment, the calculation unit 102 calculates CO2 emissions within a specific dependent range designated by the user in the hierarchical structure of the demand company (organization), based on the amount of electricity associated with the hierarchical structure and the conversion information. The calculation unit 102 calculates CO2 emissions within a specific dependent range based on the conversion information which includes the CO2 conversion coefficient for each electricity plan determined for each electricity supplier.

[0049] Furthermore, the calculation unit 102 calculates the CO2 emissions for a specific power classification within a specific dependency range, based on the power classification specified by the user. For example, the calculation unit 102 can calculate the CO2 emissions for a specific power plan within a specific dependency range, based on the power plan (such as the AAA plan) specified by the user.

[0050] The specific processing unit 103 identifies information related to power supply. In this embodiment, the specific processing unit 103 identifies the number of electricity contracts (and / or the number of power lines such as circuit breakers) within the specified dependent scope, and the usage status of said electricity contracts, based on contract information relating to electricity contracts for supplying power to each location.

[0051] The display processing unit 104 processes the display screen of the user terminal 2, etc. In this embodiment, the display processing unit 104 processes the CO2 emissions for a specific dependent range and the CO2 emissions for each location constituting the specific dependent range, based on the calculation results by the calculation unit 102, and transmits the display processing results.

[0052] Furthermore, the display processing unit 104 displays the breakdown of electricity types in CO2 emissions within a specific dependent range based on the calculation results from the calculation unit 102, and transmits the display processing results. The display processing unit 104 can also display the CO2 emissions at a selected hierarchical level in the hierarchical structure based on the calculation results from the calculation unit 102, and transmits the display processing results.

[0053] <database DB> The database DB in Figure 1 stores user information such as management personnel of demand companies, company information such as demand companies, hierarchical structure information showing the dependency relationships of multiple locations, conversion information for converting electricity consumption into CO2 emissions, electricity consumption information regarding the amount of electricity used by each demand company, and various other information necessary for electricity consumption management. Some or all of this information may be stored in the storage unit 12, or some of this information may be stored in another database, etc.

[0054] The following explanation of the power consumption management system 1 and the processing performed by each functional component will be given with reference to Figures 3 to 9.

[0055] <Overview of the Power Consumption Management System> The power consumption management system 1 according to this embodiment is a system for easily and accurately managing CO2 emissions based on the amount of electricity used in various locations for a demand company with an organizational structure that has bases scattered in various locations.

[0056] In other words, in the power consumption management system 1 according to this embodiment, within an organizational structure where various bases are scattered in different locations, it is possible to freely set a specific range (a specific location or subordinate range) according to the user's wishes, and furthermore, it is possible to manage CO2 emissions for each type of electricity as determined by the power plan and voltage supply conditions of each electric utility (power supply company) as needed. The processing flow in the power consumption management system 1 according to this embodiment will be described in detail below.

[0057] <Register various types of information> Figure 3 shows a flowchart of the processing procedure in the power consumption management system 1 according to one embodiment of the present invention. In S201, users, such as personnel belonging to a consumer company that uses electricity, register their user information in advance. In addition, the user (or the person in charge of the power consumption management system 1) also registers company information related to the consumer company to which the user belongs in advance. The acquisition unit 101 of the information processing device 10 acquires various information used for power consumption management and registers it in the storage unit 12.

[0058] In this embodiment, users include not only the management personnel of the requesting company, but also, for example, site managers of the general contractor and subcontractors at the construction site, as well as workers of subcontractors (people involved in the construction work). The personnel (management personnel) of the requesting company may belong to the head office, or to a branch office or business site.

[0059] As shown in Figure 4(a), user information is managed by a user ID, including information such as the user's name, contact information, company ID (described later), job title such as department head or section chief, assigned duties such as administrator or site supervisor, affiliation such as head office or branch office, and registration date. Similarly, as shown in Figure 4(b), company information is managed by a company ID, including information such as company name, company contact information, company address, and type such as prime contractor or subcontractor. In this embodiment, CO2 emissions can be viewed based on user information, company information, etc. For example, the scope of viewing CO2 emissions can be restricted based on attributes such as the user's job title or assigned duties.

[0060] In this embodiment, the power consumption management system 1 registers, in addition to user information and company information, information regarding the hierarchical structure showing the subordinate relationships of multiple locations within the company (hierarchical structure information), and conversion information for converting the amount of electricity for each power classification according to predetermined conditions into CO2 emissions.

[0061] Figure 5 shows a schematic diagram of the hierarchical structure used in the power consumption management system according to one embodiment of the present invention. As shown in the figure, the hierarchical structure information indicates the subordinate relationships at each location (base), such as Branch A and Branch B being linked to the head office, Business site 1 and Business site 2 being linked to Branch A, and Business site 3 and Business site 4 being linked to Branch B.

[0062] In this specification, the term "location" may be used in a broad sense to refer to multiple bases such as the head office, branches, and business sites. Business sites include factories, offices, stores, and construction sites handled by prime contractors. Furthermore, in the hierarchical structure of a client company, locations may also include non-business sites (and unlinked locations) that are not directly linked to the head office or branches. For example, this may include specific construction sites that are not linked to the head office or branches.

[0063] As shown in Figure 4(c), the hierarchical structure information is managed by a hierarchical structure ID, which includes the company ID, location name (hierarchical relationship), and other information necessary to represent the hierarchical structure within the client company. For example, the hierarchical structure information can also be constructed using the construction management system at the construction site. More specifically, the hierarchical structure information can be constructed using the hierarchical structure of the client company included in the construction management system. In this embodiment, this hierarchical structure information can be used to calculate the CO2 emissions of multiple locations (specific dependent range) that have a dependency relationship within a specific range selected by the user.

[0064] As shown in Figure 6(a), the conversion information is managed by a conversion ID and includes information such as the electricity provider (and retail electricity provider) that shares electricity with consumer companies such as XX Electric Power (XX Electric Power Co., Ltd.) and XX Power Co., Ltd., multiple electricity plans (contract plans) determined by each electricity provider, the CO2 conversion coefficient for each electricity plan, and the menu notation of public organizations such as the Ministry of the Environment that each electricity provider has submitted to public organizations. In this embodiment, by using this conversion information and the hierarchical structure information described above, a simple and accurate calculation of CO2 emissions is achieved.

[0065] Figure 7 shows a schematic diagram of the conversion information managed by the electricity management system according to one embodiment of the present invention. Each retail electricity provider is obligated to notify which of the plans set by the public body corresponds to their electricity plan (contract plan). As shown in the schematic diagram in Figure 7, for example, it is possible to associate the electricity plans provided by each retail electricity provider to each consumer company with the plans notified to the public body and determine the CO2 conversion coefficient according to these relationships. Of course, it is also possible to obtain electricity plans from general electricity providers regardless of the schematic diagram in Figure 7.

[0066] <Acquisition of power data> In S202 of Figure 3, the acquisition unit 101 of the information processing device 10 acquires the amount of electricity used by the customer company from the power DB3 and stores it in the storage unit 12 in association with the hierarchical structure of the customer company. The power DB3 stores the power classification (power plan and power type) and the amount of electricity for each power classification at each location of the customer company as power quantity information in the storage unit 12.

[0067] As shown in Figure 6(b), the electricity consumption information is managed by an electricity consumption ID, which includes information such as the company ID, hierarchical structure ID, electricity plan for each power company, electricity type such as low-voltage lighting (single-phase 100-200V, etc.), low-voltage power (three-phase 200V, etc.), high voltage, extra-high voltage, electricity consumption (kWh) and the period during which the electricity consumption was measured (not shown), the number of contracts (and / or the number of power lines) in the electricity contract to supply power to each location, and the usage status of the number of contracts. In this embodiment, the electricity contracts are the contracts for each plan at each retail electricity provider (contracts for each electricity meter or smart meter). In this specification, the number of contracts and the usage status of electricity contracts may also be referred to collectively as contract information.

[0068] In this embodiment, the acquisition unit 101 can acquire the power consumption (and power classification such as power plan and power type) of the target demand company from the power management organization DB 3(a) managed by a power management organization such as the Power Data Management Association, or directly acquire the power consumption from the demand company DB managed by the demand company. As shown in FIG. 1, the acquisition unit 101 can also acquire the power consumption of the target demand company from the electric utility company DB 3(c) managed by an electric utility company such as an electric power company.

[0069] <Calculation of CO2 emissions> In S203, the calculation unit 102 of the information processing apparatus 10 receives a specific subordinate range from the user terminal 2. The specific subordinate range here means that, for example, when the user (user terminal 2) designates (selects) the subordinate range of branch A in FIG. 5, the three bases (three locations) of branch A, workplace 1 subordinate to branch A, and workplace 2 also subordinate to branch A become the specific subordinate range. The calculation unit 102 can calculate the CO2 emissions in the designated specific subordinate range.

[0070] Also, when the user designates the subordinate range of the head office in FIG. 5, all locations of the head office, branch A subordinate to the head office, branch B, and workplaces 1 to 4 subordinate to branch A and branch B become the specific subordinate range. In this case, the CO2 emissions of all bases in the demand company are calculated.

[0071] In S204, the calculation unit 102 calculates the CO2 emissions of the specific subordinate range designated from the user terminal 2. Specifically, based on the power consumption associated with the hierarchical structure and the conversion information, the CO2 emissions of the specific subordinate range designated by the user in the hierarchical structure are calculated.

[0072] For example, when the user designates the subordinate range of branch A in the schematic image diagram of FIG. 5, the power consumption (kWh) of hierarchical structure IDs 20011 (head office), 20012 (branch A), 20014 (workplace 1), and 20015 (workplace 2) in the hierarchical structure information of FIG. 4(c) is extracted from the power consumption information of FIG. 6(b), and the CO2 emissions are calculated based on the total power consumption obtained by adding these up.

[0073] In this example, as can be seen from the electricity consumption information in Figure 4(c), the head office is under the jurisdiction of XX Electric Power, branch A is under the jurisdiction of △△ Electric Power, and business sites 1 and 2 are under the jurisdiction of ×× Power Co., Ltd. In other words, each location is under the jurisdiction of a different electricity provider, and furthermore, each electricity provider offers multiple different contract plans. In this case, since the CO2 emissions actually differ for each contract plan, it is not possible to obtain an accurate result by using a location-based CO2 conversion factor to calculate CO2 emissions.

[0074] Therefore, in this embodiment, CO2 emissions are calculated using more detailed conversion information (CO2 conversion coefficients) based on each contract of each power company according to market standards. In this embodiment, by further utilizing detailed CO2 conversion coefficients based on each contract of each power company for a specific dependent area selected by the user from among locations scattered throughout the country, it is possible to calculate CO2 emissions simply and accurately.

[0075] Furthermore, in this embodiment, in addition to calculating detailed CO2 emissions within a specific dependent range, it is possible to calculate CO2 emissions within a range that meets the user's requirements by appropriately combining and utilizing hierarchical structure information, conversion information, and electricity consumption information.

[0076] For example, the calculation unit 102 (or acquisition unit 101) can receive a specification of a specific power plan from the user and selectively calculate the CO2 emissions of a specific power plan within a specific dependency range based on the power plan specified by the user. In other words, the user can freely set the dependency range in the hierarchical structure of the demand company and the power plans used within that dependency range, and selectively calculate the CO2 emissions desired by the user based on these set conditions.

[0077] Furthermore, in this embodiment, the calculation unit 102 (or acquisition unit 101) can selectively calculate the CO2 emissions of a specific power type within a specific dependency range, based on the power type specified by the user (low-voltage lighting, low-voltage power, high voltage, extra-high voltage, etc.). In other words, the user can freely set the dependency range in the hierarchical structure of the demand company and the power type, such as three-phase 200V, used within that dependency range, and selectively calculate the CO2 emissions desired by the user based on these set conditions.

[0078] <Specific processing of electricity contracts> In S205, the specific processing unit 103 processes the number of electricity contracts and their usage status. Specifically, the acquisition unit 101 acquires contract information related to electricity contracts for supplying power to each location and stores it in the storage unit 12 in association with a hierarchical structure (electricity amount information). Then, based on the contract information, the specific processing unit 103 processes the number of electricity contracts in the specified dependent scope and the usage status of said electricity contracts.

[0079] For example, in construction sites involving large-scale projects, a single location (construction site) is divided into multiple areas for management (according to the construction period or by type of electricity), and electricity meters are installed and electricity contracts are made for each of these areas.

[0080] In this case, even if electricity meters are contracted and operational in a specific area for a predetermined period, it is possible that electricity supply has been stopped in a particular area because construction has already been completed at the present time. Also, one contract may be in one area, while multiple contracts may be in another area (or a different period). In other words, in this embodiment, in addition to being able to grasp the amount of electricity (CO2 emissions) on a per-business-site or per-construction-site basis, users can also grasp more detailed information such as the number of electricity contracts and usage status.

[0081] <Display Processing> In S206, the display processing unit 104 processes and displays various information within the specified dependent range. Figure 8 shows an example of the display processing result in the user terminal 2 according to one embodiment of the present invention. Based on the calculation result by the calculation unit 102, the display processing unit 104 processes and displays the CO2 emissions within the specified dependent range as instructed by the user, and transmits the display processing result to the user terminal 2.

[0082] As shown in Figure 8, the display screen W10 of the user terminal 2 displays a search area W20 showing the CO2 emission status search screen and a results area W30 showing the search results screen. The search area W20 displays organizational classifications such as head office, branch office, and business site, organizational name, display method of search results such as monthly or daily display, power plan for selecting the power company and the plan available from that power company, power type for selecting low voltage or high voltage, and aggregation period for selecting a specific period. The display processing unit 104 processes and displays information on CO2 emissions desired by the user based on calculation results calculated using hierarchical structure information, conversion information, and power consumption information, in response to various selection inputs from the user terminal 2.

[0083] In the search area W20, under Organization Category, users can select locations such as headquarters or branches according to their preferences. Under Organization Name, users can select a portion of the locations selected under Organization Category (for example, if the Organization Category is branches, then Branch A). For example, selecting headquarters will display CO2 emissions related to headquarters, and selecting branches will display CO2 emissions related to branches. Additionally, by selecting an Organization Name (by scrolling or typing), it is possible to select and display a portion of multiple business locations. For example, CO2 emissions can be displayed for non-business locations or unassociated locations that are not directly subordinate to headquarters, such as Site F.

[0084] Furthermore, as shown in Figure 9, when branch A is selected in the organizational classification from the user terminal 2, and a dependency relationship is selected, the display processing unit 104 processes and displays the total CO2 emissions of all locations (specific dependency range) dependent on branch A, as well as the CO2 emissions of each of those locations, in the results area W30.

[0085] In this embodiment, as shown in Figure 8 (and Figure 9), a power plan can be selected in the search area W20. A power plan is, for example, the power plan of each electric utility company shown in the conversion information in Figure 6(a). Based on the calculation results by the calculation unit 102, the display processing unit 104 can display the breakdown of power plans in the CO2 emissions within a specific dependent range and transmit the display processing results to the user terminal 2. The display processing unit 104 can also selectively display the power plan selected by the user in the CO2 emissions within a specific dependent range.

[0086] In this embodiment, the power type can be selected in the search area W20. Power types include low voltage, high voltage, extra-high voltage, etc. For example, when selecting the power type, detailed classifications such as single-phase 100V or 200V (lighting) or three-phase 200V (power) can be selected under low voltage (illustrations omitted).

[0087] The display processing unit 104 can display the breakdown of CO2 emissions by power type within a specific dependent range based on the calculation results from the calculation unit 102, and transmit the display processing results. The display processing unit 104 can also selectively display the power type selected by the user within the CO2 emissions of a specific dependent range. The user can easily and accurately check the CO2 emissions and their breakdown for each power type, such as single-phase 200V (lighting), three-phase 200V (power), high voltage, and extra-high voltage, within a certain dependent range.

[0088] In this embodiment, the organizational hierarchical structure and power classifications such as power plans and power types can be freely configured, allowing users to view and manage accurate CO2 emissions in various ways.

[0089] As described above, the power consumption management system 1 according to the present invention makes it possible to easily and accurately manage CO2 emissions in the organizational structure of demand companies scattered throughout various locations by performing predetermined processing using a hierarchical structure that shows the dependency relationships of multiple locations, as well as characteristic conversion information and power classification.

[0090] Furthermore, although this embodiment describes the power consumption management of a demand company with an organizational structure in which bases and construction sites are scattered in various locations, the same effects as the present invention can be obtained when the power consumption management system 1 is used in fields other than construction sites.
