[0003] [Patent Document 1] JP 2016-31585 A Summary of the Invention [Problem to be solved by the invention]

[0004] When evaluating the energy saving performance of a house, it is necessary to calculate the amount of greenhouse gas emissions from the house. Until now, it has not been easy to calculate the amount of energy consumption by energy type, which is necessary to calculate the amount of greenhouse gas emissions. The technology disclosed herein has been made in consideration of the above-mentioned problems, and one of the purposes is to support the calculation of the amount of energy consumption by energy type in a house. [Means for solving the problem]

[0005] In order to solve the above problems, a monitoring method of one embodiment of the present disclosure obtains data on the results of primary energy consumption calculations for a baseline home that has not yet undergone an energy conservation project, calculates greenhouse gas emissions from the baseline home based on the data on the results of primary energy consumption calculations and an emission coefficient for each energy type, and if a mixture of energy types is expected to be used for heating in the baseline home, identifies a relatively small emission coefficient from among multiple emission coefficients corresponding to the multiple energy types, calculates energy consumption for each energy type by treating the single energy type corresponding to the relatively small emission coefficient as the energy type used for heating, and calculates greenhouse gas emissions from the baseline home.

When a mixture of energy types is assumed to be used for heating in the baseline home, the calculation unit identifies a relatively small emission coefficient among multiple emission coefficients corresponding to the multiple energy types, calculates energy consumption for each energy type by considering the single energy type corresponding to the relatively small emission coefficient as the energy type used for heating, and calculates greenhouse gas emissions in the baseline home.

[0010] The subject of the device or method in this disclosure includes a computer. The computer executes a program to realize the function of the subject of the device or method in this disclosure. The computer includes a processor that operates according to a program as a main hardware configuration. The type of processor is not important as long as it can realize the function by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). Although it is called an IC or an LSI here, the name changes depending on the degree of integration, and it may be called a system LSI, a VLSI (Very Large Scale Integration), or an ULSI (Ultra Large Scale Integration). A Field Programmable Gate Array (FPGA), which is programmed after the LSI is manufactured, or a reconfigurable logic device that can reconfigure the connection relationship inside the LSI or set up the circuit partition inside the LSI, can also be used for the same purpose. Multiple electronic circuits may be integrated into one chip or provided on multiple chips. The multiple chips may be integrated in one device, or may be provided in multiple devices. The program may be recorded in a non-transitory recording medium such as a computer-readable Read Only Memory (ROM), an optical disk, or a hard disk drive, or may be recorded in a temporary storage medium such as a computer-readable Random Access Memory (RAM). The program may be stored in the recording medium in advance, or may be supplied to the recording medium or storage medium via a wide area communication network including the Internet.

[0011] The technical concept of the embodiment will be outlined below. The J-Credit Scheme has been established, in which the government certifies the amount of greenhouse gas (CO2, etc., hereinafter referred to as "GHG" (Greenhouse Gas)) emission reductions achieved through the introduction of energy-saving equipment and the use of renewable energy, and the amount of GHG absorption achieved through appropriate forest management, as credits. As described in "Methodology No. EN-S-039: New Construction of Energy-Saving Housing or Renovation to Energy-Saving Housing," the procedure for generating J-Credits requires showing how much GHG emissions have been reduced by housing after an energy-saving project has been implemented (hereinafter referred to as "housing after project implementation").

[0012] The post-project house can also be called an energy-saving house, and is, for example, a house that has been installed with devices and equipment that realizes energy conservation. On the other hand, the house that is being compared with the post-project house in terms of GHG emissions and is a baseline house where the energy conservation project has not been implemented, is hereafter also referred to as the "baseline house." The baseline house is, for example, a house that has not been installed with devices and equipment that realizes energy conservation.

[0013] In the embodiment, the energy types used to derive the GHG emissions of a house include electricity, gas, and kerosene. Gas may be city gas or LPG (Liquefied Petroleum Gas). Therefore, more specific energy types include electricity, city gas, LPG, and kerosene. For a house after the project is implemented, the energy type actually used (hereinafter referred to as "energy type") is used. For a baseline house, an assumed energy type (hereinafter referred to as "assumed energy type") is used. In the following, the baseline house and the house after the project are collectively referred to as "monitored house".

[0014] The GHG emission reduction of the house after the project is implemented can be calculated as the difference between the GHG emission of the baseline house and the GHG emission of the house after the project is implemented. The GHG emission of the baseline house and the GHG emission of the house after the project is implemented are calculated using the following formula. Baseline residential GHG emissions = Baseline home electricity consumption x electricity emission factor + City gas consumption in baseline housing × City gas emission factor + LPG consumption in the baseline residence × LPG emission factor + Amount of kerosene used in the baseline home × Emission factor for kerosene GHG emissions from housing after project implementation = Amount of electricity used in the home after the project is implemented × Electricity emission factor + City gas consumption in the home after project implementation × City gas emission factor + Amount of LPG used in the home after project implementation × LPG emission factor + Amount of kerosene used in the home after the project is implemented × Emission factor of kerosene

[0015] The emission factors for electricity, gas, and kerosene are coefficients that convert the respective amounts of energy into GHG emissions. The unit of energy is, for example, megajoules (hereinafter also referred to as "MJ"). The unit of GHG emissions is, for example, t-CO2 or t-CO2e. The emission factors for electricity, gas, and kerosene are given values ​​that may fluctuate over time. Below, the emission factors for city gas and LPG are collectively referred to as "emission factors according to gas type."

[0016] Figure 1 shows the monitoring method for determining GHG emissions. The amounts of electricity, gas, and kerosene used by the baseline house can be calculated from the results of calculating the primary energy consumption of the house as a first method. Alternatively, the figures for electricity, gas, and kerosene in the standard secondary energy consumption listed in the BELS (Building-Housing Energy-efficiency Labeling System) assessment report can be used as a second method.

[0017] As a first method, the amount of electricity, gas, and kerosene used by the home after the project is implemented can be calculated using data from the Home Energy Management System (HEMS) or meter reading slips, i.e., actual measured values. Alternatively, as a second method, the figures for electricity, gas, and kerosene in the design secondary energy consumption listed in the BELS assessment report can be used. The amount of kerosene used by the home after the project is implemented can also be calculated from the results of the primary energy consumption calculation, in which case the amount of kerosene used by the home after the project is implemented will be equal to the amount of kerosene used by the baseline home.

[0018] In the monitoring and calculation device 10 of the embodiment, actual measurements are adopted as a method for monitoring the amount of electricity, gas, and kerosene used in the house after the project is implemented. The adoption of actual measurements as a monitoring method has the following advantages, for example: (1) The amount of GHG emission reduction is linked to the actual energy consumption, so that it reflects the efforts of the residents to conserve energy. (2) It is easy to get the residents to understand and realize the amount of GHG emission reduction. (3) A costly BELS assessment report is not required. As a variant, the values ​​of electricity, gas, and kerosene of the design secondary energy consumption listed in the BELS assessment report may be used as a method for monitoring the amount of electricity, gas, and kerosene used in the house after the project is implemented.

[0019] The primary energy consumption calculation results are the results of calculations based on the Energy Conservation Law for Buildings, which is performed when designing many houses, and are the results of calculations performed by a housing company (or an external architect, etc.) using a web program. This web program may be a well-known "program that complies with the energy conservation standards for housing" (https: / / house.lowenergy.jp / ). To obtain correct calculation results for the primary energy consumption of a certain house, it is necessary to correctly input the specifications, exterior performance, and equipment specifications of the house into the web program.

[0020] Figures 2(A) and 2(B) show examples of primary energy consumption calculation results. The above web program accepts inputs of the house's specifications, exterior performance, equipment specifications, and construction site information (e.g., area classification and solar radiation classification), and outputs standard values ​​and design values ​​for heating equipment, cooling equipment, ventilation equipment, hot water equipment, lighting equipment, and other equipment. The standard value (e.g., the standard primary value in Figure 2(A)) is a value that indicates the minimum level of energy consumption that a house must meet, as stipulated by the Energy Conservation Act for Buildings. The design value (e.g., the design primary value in Figure 2(A)) is a value that indicates the anticipated energy consumption of the house.

[0021] The web program has a PDF output function and an XML output function. A two-dimensional code is added to the PDF file of the primary energy consumption calculation result, and some information on the primary energy consumption calculation result can be obtained by reading the two-dimensional code. As another method, text may be copied from the PDF file of the primary energy consumption calculation result, a paper on which the primary energy consumption calculation result is printed may be scanned and converted into text using OCR (Optical character recognition), or the operator may input the primary energy consumption calculation result. The information that can be obtained may include the area classification in which the house is located, the value of the calculation result, etc.

[0022] The BELS assessment report is a type of third-party assessment. It includes the standard secondary energy consumption and the design secondary energy consumption. By using the BELS assessment report, it is possible to calculate the GHG emissions of the baseline house even without the calculation results of the primary energy consumption. Also, by using the design secondary energy consumption, it is possible to calculate the GHG emissions of the house after the project is implemented without actual measurement.

[0023] In the following explanation, the amount of electricity, gas, and kerosene used by a home will be collectively referred to as "energy usage." In relation to Figure 1, if actual measurements are used to monitor the amount of energy used by a home after the project is implemented, it is thought that the method of monitoring the amount of energy used by the baseline home will be a method of calculating the amount from the results of primary energy consumption calculations, without using the BELS assessment report. However, until now, when multiple energy types are mixed and the composition ratio of specific equipment is unknown, it has been difficult to apportion the amount of energy used by the baseline home to the amount of energy used by each energy type (specifically, standard primary energy consumption). This issue will be explained in detail next.

[0024] Figure 3 shows the energy types assumed in the calculation of standard primary energy consumption. Continuous operation in a room is an operation in which a room is heated or cooled continuously for 24 hours regardless of whether the occupant is present or not. Intermittent operation in a room is an operation in which a room is heated or cooled only when the occupant is present. For heating homes in regions 5, 6, and 7, the energy type assumed to be used in continuous operation in a room is gas, while the energy type assumed to be used in intermittent operation in a room is electricity. In the example of Figure 2(B), the panel radiator, which is the heating equipment for the main room, corresponds to continuous operation, and the room air conditioner, which is the heating equipment for the other rooms, corresponds to intermittent operation. Therefore, in the homes for which the calculation sheets of Figures 2(A) and 2(B) were created, electricity and gas are mixed as the energy types for the heating equipment.

[0025] Figure 4 is a diagram showing the principle of the method for calculating the amount of energy for each energy type related to residential heating in regions 5, 6, and 7 when the heating system is not for the entire building. In cases where continuous operation in occupied rooms and intermittent operation in occupied rooms are mixed, the standard primary energy consumption of the heating equipment is, in principle, decomposed into the standard primary energy consumption of electricity and the standard primary energy consumption of gas. However, in practice, it has been difficult to appropriately decompose the standard primary energy consumption of the heating equipment into the standard primary energy consumption of electricity and the standard primary energy consumption of gas.

[0026] FIG. 5 is a diagram for explaining the characteristics of the monitoring and calculation device of the embodiment. As shown in FIG. 5, when the heating method of the main room of the house is different from the heating method of the other rooms, the monitoring and calculation device of the embodiment selects an energy type corresponding to a relatively small emission coefficient among the emission coefficient of electricity with the unit per MJ and the emission coefficient according to the gas type. The difference in the heating method of the main room of the house and the heating method of the other rooms includes the heating method of the main room of the house being an intermittent operation and the heating method of the other rooms being a continuous operation, or conversely, the heating method of the main room of the house being a continuous operation and the heating method of the other rooms being an intermittent operation. A relatively small emission coefficient can be said to be an emission coefficient that results in a smaller conversion value of GHG emissions, and can also be said to be an emission coefficient that conservatively calculates the GHG emission reduction amount by calculating the GHG emissions of the baseline house to be smaller. The monitoring and calculation device of the embodiment can identify the standard primary energy consumption value of a heating equipment listed in the primary energy consumption calculation result as either electricity or gas without decomposing the standard primary energy consumption value of the heating equipment into electricity and gas.

[0027] An embodiment of a monitoring and calculation device that embodies the above technical concept will now be described in detail. Fig. 6 is a block diagram showing the functional blocks of the monitoring and calculation device 10 of the embodiment. Each block shown in the block diagram of the present disclosure can be realized in hardware terms by elements and mechanical devices such as a computer's CPU and memory, and in software terms by a computer program, etc., but here, the functional blocks realized by their cooperation are depicted. Those skilled in the art will understand that these functional blocks can be realized in various forms by combining hardware and software.

[0028] The monitoring and calculation device 10 is an information processing device that supports visualization of the GHG emission reduction amount in a house after the project is implemented. The monitoring and calculation device 10 includes a processing unit 12, a memory unit 14, and a communication unit 16. The processing unit 12 executes information processing related to calculation of the GHG emission reduction amount in a house after the project is implemented. The processing unit 12 may be realized by a processor (such as a CPU) of the monitoring and calculation device 10. The memory unit 14 stores data referenced or updated by the processing unit 12. The communication unit 16 communicates with an external device according to a predetermined communication protocol. The processing unit 12 transmits and receives data to and from the external device via the communication unit 16.

[0029] The storage unit 14 includes a submitted information storage unit 20, a coefficient storage unit 22, a standard primary energy consumption by energy type storage unit 24, an actual measurement value storage unit 26, an emission amount storage unit 28, and an emission reduction amount storage unit 30. The submitted information storage unit 20 stores various information submitted by users. For example, the submitted information storage unit 20 stores information described in the primary energy consumption calculation results obtained for the monitored house, as exemplified in FIG. 2. The submitted information storage unit 20 further stores information described in the BELS assessment report, and information on membership notices, change notices, and withdrawal notices submitted by users.

[0030] The coefficient storage unit 22 stores various coefficients input or acquired by the coefficient input unit 50 described below. For example, the coefficient storage unit 22 stores the emission coefficient value for electricity, the emission coefficient value according to the gas type, and the emission coefficient value for kerosene.

[0031] The standard primary energy consumption for each energy type storage unit 24 stores information indicating the type of energy expected to be used for each combination of the area classification and the equipment type shown in Fig. 3. The standard primary energy consumption for each energy type storage unit 24 further stores the standard primary energy consumption for each energy type expected in the baseline house, calculated based on the primary energy consumption calculation result.

[0032] The actual measurement value storage unit 26 stores data on the amount of energy consumption measured for the house after the project is implemented (actual measurement data, so to speak). For example, the actual measurement value storage unit 26 stores values ​​of the amount of electricity used, the amount of electricity purchased, the amount of gas used, and the amount of kerosene used that are actually measured for the house after the project is implemented.

[0033] Emissions amount storage unit 28 stores data on GHG emissions for the baseline residence calculated by a baseline residence emissions calculation unit 42 described below. Emissions amount storage unit 28 also stores data on GHG emissions for the post-project residence calculated by a post-project emission calculation unit 46 described below. Emissions reduction amount storage unit 30 stores data on GHG emission reductions for the post-project residence calculated by an emission reduction amount calculation unit 48 described below.

[0034] The processing unit 12 includes a submission information input unit 40, a baseline residential emission calculation unit 42, an actual measurement input unit 44, a post-project emission calculation unit 46, an emission reduction calculation unit 48, and a coefficient input unit 50. The functions of these multiple functional blocks may be implemented in a computer program (hereinafter also referred to as a "monitoring program"). The monitoring program may be stored in a recording medium, or may be installed in the storage of the monitoring and calculation device 10 via the recording medium. The processor of the monitoring and calculation device 10 may fulfill the functions of the above multiple functional blocks by reading the monitoring program into a main memory and executing it.

[0035] The submitted information input unit 40 acquires various information (hereinafter also referred to as "submitted information") submitted by users. The users include, for example, members of the project, housing companies, and employees of housing companies. In other words, the users include those who perform emission reduction activities, and also include housing companies and their employees as agents for document submission, etc. The submitted information input unit 40 may accept information submitted by those who wish to obtain membership. The submitted information input unit 40 may accept submitted information transmitted from a user's terminal, or may acquire information input to the monitoring and calculation device 10 by an operator of the monitoring and calculation device 10, etc., based on the submitted information from the user. The submitted information input unit 40 accepts input of information included in various notifications such as membership notifications, such as primary energy consumption calculation results, and information described in documents such as BELS assessment reports. The submitted information input unit 40 may acquire information necessary for calculating the GHG emission reduction amount of the monitored home from information described in the primary energy consumption calculation results of the monitored home. The information obtained from the information described in the primary energy consumption calculation result includes the area classification, the heating method of the heating equipment, the type of heating equipment, the standard primary energy consumption of the heating equipment, etc. The submitted information input unit 40 may also obtain information necessary for calculating the GHG emission reduction amount of the monitored home from the information described in the BELS assessment report of the monitored home. The information obtained from the information described in the BELS assessment report includes the standard secondary energy consumption, etc.

[0036] The baseline housing emission calculation unit 42 calculates the GHG emissions for the baseline housing based on the data of the primary energy consumption calculation results for the baseline housing or the data of the BELS assessment report obtained by the submission information input unit 40 and the emission coefficients for each energy type stored in the coefficient memory unit 22.

[0037] The baseline home emission calculation unit 42 calculates the GHG emissions of the baseline home. The baseline home emission calculation unit 42 identifies the region in which the baseline home indicated by the primary energy consumption calculation result is located, the type of heating equipment installed in the baseline home, and the type of energy assumed to be used for heating in the baseline home. For example, the baseline home emission calculation unit 42 may identify the type of energy assumed to be used for heating in the baseline home based on information indicating the type of energy assumed to be used, stored in the standard primary energy consumption storage unit 24 for each energy type, as exemplified in FIG. 3.

[0038] When multiple energy types are assumed to be used for heating in the baseline home, the baseline home emission calculation unit 42 specifies one type. In the embodiment, the baseline home emission calculation unit 42 calculates the GHG emissions in the baseline home by considering an energy type that corresponds to a relatively small emission coefficient after aligning the units among the multiple energy types assumed to be used for heating as the energy type used for heating.

[0039] Specifically, when a first energy type (e.g., gas) is assumed as the energy type used by a first heating equipment installed in the baseline home, and a second energy type (e.g., electricity) is assumed as the energy type used by a second heating equipment installed in the baseline home, the baseline home emission calculation unit 42 unifies the units of the emission coefficients of the first energy type and the second energy type, and unifies them into an energy type with a relatively small emission coefficient. The baseline home emission calculation unit 42 identifies the energy type corresponding to the relatively small emission coefficient between the first energy type and the second energy type as the energy type used for heating.

[0040] For example, assume that electricity is specified as the type of energy used for heating. In this case, the baseline home emission calculation unit 42 may calculate the amount of electricity used in the baseline home by specifying the primary energy consumption of the heating equipment as the amount of electricity used for heating and adding it to the amount of electricity used for other equipment such as a hot water supply equipment. The baseline home emission calculation unit 42 may calculate the product of the amount of electricity used in the baseline home and the emission coefficient of electricity as the amount of GHG emissions based on the amount of electricity used in the baseline home. The baseline home emission calculation unit 42 may calculate the sum of the amount of GHG emissions based on the amount of electricity used, the amount of GHG emissions related to the amount of city gas used, the amount of GHG emissions related to the amount of LPG used, and the amount of GHG emissions based on the amount of kerosene used as the amount of GHG emissions of the baseline home, as shown in the above formula.

[0041] The actual measurement value input unit 44 acquires data on energy consumption actually measured in the monitored home (e.g., the baseline home and the home after the project is implemented) from an external device (such as a HEMS). The actual measurement value input unit 44 also acquires data on energy consumption actually measured in the monitored home that is written on a meter reading slip. The actual measurement value input unit 44 stores the data on energy consumption measured in the monitored home in the actual measurement value storage unit 26. The energy consumption data here can also be called the actual measurement value of energy consumption. As a modified example, the actual measurement value input unit 44 may acquire the actual measurement value of energy consumption measured in the monitored home that is input to the monitoring and calculation device 10 by the operator based on HEMS data submitted by the user, meter reading slips, etc.

[0042] The post-project implementation emission calculation unit 46 calculates the GHG emission amount in the house after the project is implemented based on the energy consumption measured for the house after the project is implemented and stored in the actual measurement value storage unit 26, and the emission coefficient for each energy type stored in the coefficient storage unit 22. As a modified example, the post-project implementation emission calculation unit 46 may calculate the GHG emission amount in the house after the project is implemented based on the information described in the BELS assessment report stored in the submission information input unit 40, and the emission coefficient for each energy type stored in the coefficient storage unit 22.

[0043] The emission reduction calculation unit 48 calculates the GHG emission reduction amount in the post-project home by determining the difference between the GHG emission amount in the baseline home and the GHG emission amount in the post-project home.

[0044] The coefficient input unit 50 acquires various coefficients for calculating GHG emissions from an external device, or accepts input of the various coefficients from outside, including an operator, etc. The coefficient input unit 50 stores the accepted various coefficients in the coefficient storage unit 22. The various coefficients include emission coefficients for each energy type and coefficients for unit conversion.

[0045] The operation of the monitoring and calculation device 10 configured as above will now be described. 7 is a flowchart showing the operation of the monitoring and calculation device 10. The coefficient input unit 50 of the monitoring and calculation device 10 stores various coefficients for calculating GHG emissions input from outside in the coefficient storage unit 22 (S10). The submitted information input unit 40 of the monitoring and calculation device 10 acquires submitted information such as various reports input from outside, and stores the submitted information in the submitted information storage unit 20 (S12).

[0046] For example, a device of a housing company that builds or sells a monitored house (baseline house, post-project house) may register data (e.g., a PDF file) of primary energy consumption calculation results created for the monitored house using a web program in the monitoring and calculation device 10. The submitted information input unit 40 of the monitoring and calculation device 10 may obtain the registered primary energy consumption calculation results from an external device and store them in the submitted information storage unit 20.

[0047] The submitted information input unit 40 of the monitoring and calculation device 10 may acquire data on the calculation result of primary energy consumption for the baseline home from the data on the calculation result of primary energy consumption for the monitored home stored in the submitted information storage unit 20. The data on the calculation result of primary energy consumption for the baseline home includes the area classification and primary energy consumption (reference primary value) shown in Fig. 2(A). It also includes the heating method and equipment specifications shown in Fig. 2(B).

[0048] The baseline residential emission calculation unit 42 of the monitoring and calculation device 10 identifies the assumed energy type used by each facility indicated by the calculation result of primary energy consumption for the baseline residential house based on the information indicating the energy type assumed in the calculation of the standard primary energy consumption stored in the standard primary energy consumption storage unit 24 for each energy type (S14). For example, each of the cooling facility, ventilation facility, hot water supply facility, and lighting facility is assigned one assumed energy type based on the area classification. In addition, the heating facilities in area classifications 1, 2, 3, and 4 are assigned one assumed energy type based on whether they are operated continuously throughout the entire building or only in occupied rooms.

[0049] On the other hand, for heating equipment in regional categories 5, 6, and 7, the baseline residential emission calculation unit 42 identifies the assumed energy type of the heating equipment according to the logic shown in Fig. 5. Specifically, if the heating equipment in the main room and the heating equipment in the other rooms are both associated with intermittent operation, the baseline residential emission calculation unit 42 selects electricity as the assumed energy type of the heating equipment. On the other hand, if the heating equipment in the main room and the heating equipment in the other rooms are both associated with continuous operation, the baseline residential emission calculation unit 42 selects gas as the assumed energy type of the heating equipment.

[0050] If the heating equipment in the main room is associated with intermittent operation and the heating equipment in the other rooms is associated with continuous operation, or if the heating equipment in the main room is associated with continuous operation and the heating equipment in the other rooms is associated with intermittent operation, baseline residential emission calculation unit 42 converts the electricity emission coefficient to per MJ, compares the converted electricity emission coefficient with the emission coefficient corresponding to the gas type, and selects the energy type corresponding to the relatively smaller emission coefficient as the assumed energy type for the heating equipment.

[0051] The baseline home emission calculation unit 42 calculates the energy consumption for each energy type in the baseline home based on the energy consumption of each piece of equipment (corresponding to a specific energy type) related to the baseline home acquired in S12 and the assumed energy type of each piece of equipment identified in S14. The baseline home emission calculation unit 42 calculates the GHG emission amount for each energy type by multiplying the energy consumption for each energy type by the emission coefficient for each energy type, and calculates the GHG emission amount for the entire baseline home by summing up the GHG emission amounts for each energy type (S16). The baseline home emission calculation unit 42 stores the GHG emission amount for the entire baseline home in the emission memory unit 28.

[0052] The actual measurement value input unit 44 of the monitoring and calculation device 10 acquires data of the energy consumption amount actually measured in the house after the project is implemented (so to speak, actual measurement value) from an external device (S18). The actual measurement value input unit 44 stores the acquired energy consumption amount data in the actual measurement value storage unit 26. The external device here may be a HEMS device (e.g., a HEMS controller) or a device of an electric power company or a gas company that manages meter reading slip data. In addition, the actual measurement value input unit 44 may accept data of the energy consumption amount actually measured in the house after the project is implemented that is actively provided from the external device side, and store the data in the actual measurement value storage unit 26. In addition, as described above, the actual measurement value input unit 44 may acquire the actual measurement value input by the operator to the monitoring and calculation device 10 based on the HEMS data, meter reading slip, etc. submitted by the user.

[0053] The data of the energy consumption actually measured in the house after the project is implemented includes the actual measured values ​​of the amount of electricity used, the amount of electricity purchased, the amount of gas used, and the amount of kerosene used. The emission calculation unit 46 after the project is implemented of the monitoring and calculation device 10 calculates the GHG emission amount for electricity by multiplying the amount of electricity purchased by the emission factor for electricity. Also, the emission calculation unit 46 calculates the GHG emission amount for gas by multiplying the actual measured value of the amount of gas used by the emission factor according to the type of gas. Also, the emission calculation unit 46 calculates the GHG emission amount for kerosene by multiplying the actual measured value of the amount of kerosene used by the emission factor for kerosene.
