Description

  The present invention relates to an energy saving activity management apparatus, an energy saving activity management method, and a program for evaluating energy saving activities in a consumer.

  2. Description of the Related Art Conventionally, techniques for evaluating carbon dioxide emissions at consumers have been proposed. For example, Patent Document 1 discloses a technique for calculating the amount of carbon dioxide emissions in a home from the amount of energy used in the home (customer) and the reference emissions determined in the home. Japanese Patent Application Laid-Open No. H10-228707 describes that the amount of carbon dioxide emission is recognized by calculating a conversion amount corresponding to the amount of carbon dioxide emission for each household.

JP 2009-289171 A

  However, the technique described in Patent Document 1 only converts the amount of energy used to the amount of carbon dioxide emissions. For example, as in the case where a consumer has a solar power generation device, the energy Reduction of carbon dioxide emissions associated with the creation of In recent years, devices that not only consume energy resources but also create and store energy resources have become widespread in consumers, and a mechanism to evaluate not only consumption of energy resources but also supply has become necessary. ing.

  When equipment that creates and accumulates not only energy resources but also creates and accumulates is provided, equipment that monitors the entry and exit of energy in individual equipment is provided, but this equipment leads to the reduction of carbon dioxide emissions. It is difficult for the user to recognize whether or not. In addition, even if the input / output of energy is monitored for each device, it is difficult for the user to recognize whether or not the user contributes to an energy-saving activity such as carbon dioxide emission.

  The present invention uses a measured amount related to the use of energy resources as an index value of environmental load, and presents a centralized evaluation value for representing a degree of contribution related to reduction of the environmental load of the consumer to the consumer. The purpose is to provide an energy saving activity management device that makes it possible to easily recognize the degree of contribution to the environment, and to provide an energy saving activity management method and program.

  In order to achieve the above object, the energy saving activity management apparatus according to the present invention acquires a measurement amount related to the use of energy resources in a consumer as an index value of environmental load, and the measurement amount acquired by the acquisition unit And a storage unit that stores the information in association with the consumer, and a standard measurement amount statistically obtained from the measurement amounts of a plurality of consumers in a certain period, or the measurement amount in a certain past period of the consumer Based on the monitoring result of the presence / absence monitoring unit, the storage unit stores the reference value storage unit for storing the reference value defined based on the presence / absence, the presence / absence monitoring unit for monitoring the presence / absence of a person in the consumer, A calculation unit that calculates an energy-saving activity point representing a degree of contribution related to reduction of environmental load by comparing the measured amount with the reference value stored in the reference value storage unit; The energy conservation point of each customer and a presenting unit for presenting to a user equipment of the customer.

  In this energy-saving activity management device, the presence / absence monitoring unit has a function of detecting the number of persons existing in the consumer, and the arithmetic unit is detecting the presence of a person in the consumer by the presence / absence monitoring unit. It is preferable to convert the measured amount per person per unit time in the period into energy saving activity points.

  In this energy-saving activity management device, the calculation unit obtains the existence rate that the period in which the presence / absence monitoring unit detects the presence of a person occupies a prescribed period, and when the existence rate is equal to or greater than a prescribed value, Is preferably calculated.

  In the energy saving activity management method according to the present invention, an acquisition unit acquires a measurement amount related to use of energy resources in a consumer as an index value of environmental load, and associates the measurement amount acquired by the acquisition unit with the consumer. Storing in the storage unit, the presence / absence monitoring unit monitors the presence / absence of a person in the consumer, and the arithmetic unit based on the monitoring result of the presence / absence monitoring unit, the measurement amount and the reference stored in the storage unit By comparing with the reference value stored in the value storage unit, energy saving activity points representing the degree of contribution related to the reduction of the environmental load are calculated, and the reference value is statistically calculated from the measured amounts of a plurality of consumers in a certain period. It is defined on the basis of the standard measured quantity obtained or the measured quantity of the consumer over a certain period in the past, and the presentation unit displays the energy saving activity point for each consumer obtained by the calculation unit. Characterized in that it presented to the house of the user device.

  The program according to the present invention is a program for causing a computer to function as an energy saving activity management device, and the energy saving activity management device acquires a measurement amount related to the use of energy resources in a consumer as an index value of environmental load. An acquisition unit, a storage unit that stores the measurement amount acquired by the acquisition unit in association with the consumer, and a standard measurement amount statistically obtained from the measurement amounts of a plurality of consumers in a certain period, or A reference value storage unit that stores a reference value defined based on the measured amount in a certain period in the past of the consumer, a presence / absence monitoring unit that monitors presence / absence of a person in the consumer, and a presence / absence monitoring unit Based on the monitoring result, the measurement amount stored in the storage unit is compared with the reference value stored in the reference value storage unit, thereby contributing to the reduction of environmental load. A calculator for calculating the energy conservation point representing the degree, characterized in that the energy conservation point of each of the customer to the arithmetic unit is determined and a presentation unit that presents to the user equipment of the customer.

  According to the configuration of the present invention, energy saving activity points are given to consumers as a centralized evaluation value for representing the degree of contribution related to reduction of environmental loads in consumers by using the measured amount related to the use of energy resources as an index value of environmental loads. Therefore, there is an advantage that the degree of contribution to the society related to energy saving can be shown in an easy-to-understand manner to the consumer rather than showing the consumption of energy resources numerically to the consumer.

It is a block diagram which shows embodiment. It is operation | movement explanatory drawing which shows the operation example same as the above.

  In the following, although the case where the consumer is a detached house is shown, the technical concept described in the present embodiment is also applied to the case where the consumer is a dwelling unit of an apartment house or the consumer is a tenant of an office building or a commercial building. Is applicable.

  In the following, for ease of explanation, the case where the “energy resource” is electric power is taken as an example, but the energy resource may be city gas, propane gas such as propane gas, kerosene, gasoline, etc. Good. This type of energy resource has the common feature that a consumer purchases from a supplier and is consumed as energy is used.

  In addition, energy resources, such as city water supplied through waterworks, are rarely used directly for energy use, but they need to be purchased from suppliers, and suppliers need to supply It may contain resources that require energy consumption. This type of energy resource is consumed indirectly by being consumed by consumers.

  In other words, it can be said that there are a case where greenhouse gas typified by carbon dioxide is discharged as energy resources are consumed and a case where greenhouse gas is discharged during the generation process of energy resources. In any case, when consumers use this kind of energy resource, the amount of greenhouse gas (in this case, carbon dioxide) increases as the amount of energy resource used increases. Thus, energy resources that are considered to lead to an increase in greenhouse gases when consumed by consumers are hereinafter referred to as “depletion energy resources”.

  On the other hand, a technology that hardly affects the total amount of greenhouse gases in the process of generating energy resources has been proposed. For example, energy resources generated from natural energy such as sunlight, hydropower and wind power (mainly electric power), energy resources generated from biomass (electric power, alternative fuel for gasoline and kerosene, methane gas, etc.) Looking at it, it is thought to have little effect on the total amount of greenhouse gases. Therefore, when consumers use this type of energy resource, it can be said that greenhouse gas emissions do not increase even if the amount of energy resource used increases. Energy resources that are considered not to increase greenhouse gas even if consumed by consumers in this way are hereinafter referred to as “renewable energy resources”.

  As is clear from the above description, if a consumer uses renewable energy resources, the rate of using depleted energy resources decreases. In other words, if the total amount of energy resources used by consumers does not change, the amount of greenhouse gas emissions decreases as the proportion of consumers using renewable energy resources increases. Renewable energy resources may be included in energy resources purchased from suppliers. For example, when green power is included in the power purchased from the supplier, the depletion energy resource is reduced as compared with the case of purchasing power that does not include green power.

  Activities that consumers perform to reduce the use of depleted energy resources in order to reduce greenhouse gas emissions are referred to below as “energy saving activities”. Energy conservation activities are activities that reduce the use of depleted energy resources and reduce greenhouse gas emissions. Therefore, in general, reducing the use of energy resources by consumers and the use of energy resources. It refers to the efficient use of energy resources without waste. Energy saving activities also include generating and using renewable energy resources at consumers and increasing the percentage of purchasing renewable energy resources from suppliers.

  Speaking of energy resources only for electric power, energy saving activities are mainly to reduce the amount of electric power used for a predetermined period (such as one month or one year). Therefore, it is conceivable that the energy saving activities include shortening the usage time of the electrical load, reducing the instantaneous power used by the electrical load, and using an electrical load having a small rated power for the function. Here, reducing the instantaneous power used by the electric load includes raising the preset temperature of the air conditioner during cooling, raising the preset temperature of the refrigerator, and the like. In other words, an electric load with a small rated power for the function is an electric load with high power use efficiency, and if it is a target item of the energy saving label, the description content of the energy saving label may be selected as a guide.

  When a consumer is equipped with a power generation device such as a solar power generation device, use of the generated power without waste is also included in the energy saving activities. Utilizing the generated power without waste means performing a reverse flow of surplus power, storing surplus power in a power storage device, and using the power later without discarding the surplus power.

  As described above, when the power generated by the power generation device is used without waste, the amount of power used is hereinafter referred to as “supply amount”. In other words, the supply amount corresponds to the amount of power generated by the power generation device, assuming that the power generated by the power generation device is used without waste. On the other hand, when the power generated by the depleted energy resource is purchased, the amount of power used is referred to as “consumption” below. The consumption amount, when simply formulated, is equivalent to the amount of electric power purchased from the supply company (electricity company).

  Since the consumption amount and the supply amount are amounts that are measured with respect to the use of energy resources by consumers, hereinafter, the consumption amount and the supply amount are collectively referred to as a measurement amount unless there is a need for distinction. For a consumer who does not have a power generation device or a power storage device, the measured amount is only a consumption amount. For a consumer who has a power generation device or a power storage device, the measurement amount includes a consumption amount and a supply amount. Of the measured amount, the consumption amount is an index value of the amount of depleted energy resources consumed, and the supply amount is an index value of the amount using renewable energy resources. In other words, the measured amount can be used as an index value of the environmental load at the consumer. Hereinafter, the case where the measured amount includes the consumption amount and the supply amount will be described as an example.

  Here, the reverse power flow of surplus power can be said to be an energy saving activity because it increases the ratio of renewable energy resources (green power) in other consumers. Further, storing the surplus power in the power storage device and using it later can be said to be an energy saving activity because the amount of power as a depletion energy resource purchased from the supplier is reduced. Furthermore, if it is necessary to limit the amount of power flowing into the power system of the commercial power source due to reverse power flow in order to maintain the power quality of the power system of the commercial power source, surplus power can be reduced by using a power storage device. Since the possibility of disposal is reduced, power storage in the power storage device becomes an energy saving activity.

  The present embodiment provides a technique for quantitatively measuring the energy saving activity as described above, and further, the energy measurement activity quantitatively measured is converted into a carbon dioxide gas that is a target of trading in the greenhouse gas. Provide a configuration that converts to carbon emissions.

  In the configuration example illustrated in FIG. 1, an electric load 21 that consumes electric power, a power generation device 22 that generates power using natural energy, such as a solar power generation device, and an electric load 21 among electric power generated by the power generation device 22. And a power storage device 23 that stores surplus power that has not been consumed. The electrical load 21, the power generation device 22, and the power storage device 23 are connected via a distribution board 20, and the distribution board 20 is connected to a power system 31 of a commercial power source. The electric power stored in the power storage device 23 is supplied to the electric load 21 as necessary.

  The power generation device 22 is not limited to a solar power generation device, and may be a wind power generation device, a power generation device using a fuel cell, a power generation device using a micro gas turbine, or the like. A power generator using a fuel cell or a micro gas turbine is often configured not only to supply power but also to supply heat, and constitutes a so-called cogeneration system. Therefore, the consumption of energy resources is reduced as compared with the case where the power generator and the water heater are provided separately.

  In the following description, it is assumed that surplus power generated in the power generation device 22 is stored in the power storage device 23 and is not discarded. However, a configuration in which surplus power is reversely flowed into the power system 31 of the commercial power supply, or a configuration in which a part of surplus power is discarded when reverse power flow or storage of surplus power cannot be performed may be employed. The condition for supplying the electric power stored in the power storage device 23 to the electric load 21 is that the electric power required by the electric load 21 cannot be satisfied by the output power of the power generation device 22. Supplied. Furthermore, when the power from the power storage device 23 cannot satisfy the shortage, the power is supplied from the power system 31 of the commercial power source.

  The distribution board 20 includes a power consumption measuring unit 201 that measures the amount of power per unit time consumed by the electrical load 21 and a generated power measuring unit 202 that measures the amount of power per unit time generated by the power generation device 22. In addition, the distribution board 20 includes a charge / discharge power measuring unit 203 that measures the power stored in the power storage device 23 and the power discharged from the power storage device 23. The power consumption measuring unit 201, the generated power measuring unit 202, and the charge / discharge power measuring unit 203 are not necessarily provided in the distribution board 20, and may be provided separately from the distribution board 20. In addition, in order to measure the power purchased from the power system 31 of the commercial power source and the power that performs the reverse power flow to the power system 31 of the commercial power source, the power source side of the main breaker (not shown) provided in the distribution board 20 , A trading power measuring unit 204 is provided.

  A consumer device 40 that communicates with the energy saving activity management apparatus 10 including a computer server through a public network 41 such as the Internet is installed at the consumer. That is, the user device 40 collects measurement values from the power consumption measurement unit 201, the generated power measurement unit 202, the charge / discharge power measurement unit 203, and the trading power measurement unit 204, and the collected measurement values are stored in the energy saving activity management apparatus 10. It has a function to transmit. The measured values measured by the power consumption measuring unit 201, the generated power measuring unit 202, the charge / discharge power measuring unit 203, and the trading power measuring unit 204 are constant time intervals (for example, 30 seconds, 1 for the user device 40). Min., 5 minutes, etc.) regularly. The user device 40 stores the measurement values collected over a relatively long period of time (for example, 30 minutes, one day, one week, one month, etc.) together with the measurement date and time, and the collected measurement values and date and time for each customer. Are transmitted to the energy saving activity management apparatus 10 together with the customer ID set to "."

  As described above, the user device 40 has a function of collecting measurement values from the power consumption measurement unit 201, the generated power measurement unit 202, the charge / discharge power measurement unit 203, and the trading power measurement unit 204. In addition, the user device 40 has a function of storing measurement values, a function of transmitting measurement values to the energy saving activity management device 10, and a function of presenting information transmitted from the energy saving activity management device 10. Information transmitted from the energy saving activity management device 10 is basically displayed on a display device (not shown) provided in the user device 40. Therefore, the user device 40 needs to include a display device including a liquid crystal display.

  The user device 40 may also be used as a personal computer, a home appliance with a communication function, a mobile terminal, etc., in addition to a dedicated control device used for energy management in a consumer. In order to use these devices as the user equipment 40, it is necessary to have an interface device for acquiring measurement values and to be able to execute a dedicated program.

  In the user device 40, the function of communicating with the energy saving activity management device 10 and the function of displaying by the display device may be provided separately in different containers. For example, in the case where a home server for managing residential equipment using communication technology is provided, the home server communicates with the energy-saving activity management device 10 and the energy-saving activity management device is displayed on the display device of the terminal device that can communicate with the home server. Information from 10 may be displayed.

  The energy saving activity management apparatus 10 acquires the measured value for a certain period from the user device 40 together with the customer ID for each individual customer. Therefore, the energy saving activity management apparatus 10 includes an acquisition unit 11 that acquires measurement values for a certain period of energy resources (electric power) measured by a consumer. The energy saving activity management apparatus 10 is realized by executing a program for realizing the functions described below using a computer as a main hardware component.

  The power consumption is the amount of power purchased from the power system 31 of the commercial power supply, and includes the consumption of depletion energy resources, and is obtained from the measured value of the trading power measuring unit 204. When the supplier (electric power company) discloses the ratio of green power, the ratio of the amount of power purchased from the power system 31 of the commercial power source is allocated to the supply amount of renewable energy resources. An operation is performed. This calculation is performed in the calculation unit 13 described later.

  The amount of power supplied uses the amount of power generated by the power generation device 22, the amount of power used by the electrical load 21, the amount of power stored in the power storage device 23, and the amount of power purchased and sold with the power system 31 of the commercial power source. Sought by.

  The power consumption and supply amount will be described in more detail. The amount of power measured by the consumer is generally the amount of power Qc consumed by the electrical load 21, the amount of power Qb purchased from the power system 31, the amount of power Qs stored in the power storage device 23, and the amount of power Qr subjected to reverse power flow. This is the amount of power Qg generated by the power generation device 22 and includes a loss. Of these, the generated power amount Qg, the reverse power flow amount Qr, and the stored power amount Qs are the power amounts corresponding to the renewable energy resources, so the magnitudes of the power amounts Qg, Qr, and Qs are: It can be said that it represents the degree of reduction of environmental load. In addition, since the purchased power amount Qb and the consumed power amount Qc reflect the degree of consumption of the depleted energy resource, the magnitudes of the power amounts Qc and Qb are reduced from appropriately set reference values. By calculating the minutes, the degree of reduction of environmental load is expressed.

  An operation example is given. Now, assuming that the generated power amount Qg is larger than the consumed power amount Qc and all of the surplus power (= Qg−Qc) is stored in the power storage device 23, the stored power amount Qs is Qs = Qg−. Qc. In this case, the electric load 21 is operated without consuming exhaustive energy resources. In the future, the consumption of depletion energy resources will be reduced by the amount of power Qs stored in the power storage device 23. In other words, the sum of the power amount Qc consumed by the electrical load 21 and the power amount Qs stored in the power storage device 23 corresponds to the power supply amount. Only when a part of the surplus power is stored in the power storage device 23 and the remainder of the surplus power is discarded, the power amount Qc consumed by the electric load 21 and the power amount Qs stored in the power storage device 23 are the amount of power supplied. It corresponds to.

  After all, when there is no surplus power, the power consumption corresponds to the consumption of exhaustive energy resources, and when surplus power is generated, the amount of power supply is reduced by suppressing the consumption of exhaustive energy resources. It can be said that it corresponds to.

  By the way, the energy-saving activity management apparatus 10 is provided with the memory | storage part 12 which memorize | stores the measured value which the acquisition part 11 acquired, and the memory | storage part 12 matched the customer ID for every consumer, the measured value, and the measured date. Remember. Furthermore, the energy-saving activity management device 10 uses the measured value stored in the storage unit 12 as the measured amount of power consumption and supply in a predetermined period (for example, one month, one year, etc.) for each consumer. The calculating part 13 to calculate is provided. Electricity consumption and supply are measured quantities related to the use of energy resources by consumers, and these measured quantities serve as index values for environmental loads. Therefore, the calculation unit 13 converts the measured amount of power into an evaluation value that indicates the degree of contribution related to reduction of the environmental load. That is, it is determined that the consumption of the depletion energy resource has been reduced, and it has been converted to an appropriate evaluation value for evaluating the contribution. Hereinafter, this evaluation value is referred to as “energy saving activity point”. The energy saving activity point is calculated by converting the measured amount of electric power measured by the consumer at an appropriate conversion rate for each type of consumption and supply. For example, for power amounts Qg, Qr, and Qs, type points are assigned to the amounts, and for power amounts Qc and Qb, type points are assigned to differences from the reference value, and the total value thereof. May be calculated as the current energy saving activity point.

  As described above, the consumption of the depleted energy resource increases the emission amount of carbon dioxide, so that the power measurement amount can be converted into the emission amount of carbon dioxide. In addition, it can be said that energy saving activity points are given when contributing to the reduction of carbon dioxide emissions. In other words, if the conversion rate for converting the measured amount of electric power into energy saving activity points is appropriate, the amount of carbon dioxide emission reduction is represented by the energy saving activity points. In general, the degree of contribution to reducing carbon dioxide emissions is evaluated by a relative value to a reference value, as is known in emissions trading. That is, in order to calculate the energy saving activity point in the calculation unit 13, a reference value storage unit 15 for storing a reference value for the measured amount of electric power is provided.

  The reference value stored in the reference value storage unit 15 employs one of the following two types. That is, as the first reference value, a standard measurement value of electric power in a certain period (for example, one month or one year) obtained from the family structure, building size, facility size, or the like is used. This reference value is a designated value set using information statistically obtained from a plurality of consumers. As the second reference value, it is possible to use the actual value of the measured amount of power in a certain period in the past in the consumer. This reference value is obtained from the measured amount stored in the storage unit 12. That is, the calculation unit 13 obtains, for each customer stored in the storage unit 12, a measured amount of power (usually an integrated amount) in a past fixed period as an actual value, and the obtained actual value is used as a reference value. It is stored in the reference value storage unit 15.

  Further, the calculation unit 13 uses the measured amount of power stored in the storage unit 12 to calculate a measurement amount in a period that can be compared with the period for which the actual value is obtained, and stores the measurement amount in the reference value storage unit 15. Find the difference from the reference value. Since the standard value corresponds to the consumption of depleted energy resources, this difference corresponds to the amount of carbon dioxide emission reduction in the carbon dioxide emission trading. Therefore, if this difference is converted into an energy saving activity point, it becomes possible to estimate the amount of reduction of carbon dioxide emissions by the customer using the energy saving activity point. In conversion to energy saving activity points, it is preferable to determine the conversion rate in consideration of power loss for the measured amount of power.

  The energy saving activity points calculated by the calculation unit 13 are transmitted from the presentation unit 14 to the user device 40 through the public network 41 to the user specified by the customer ID and displayed on the display device of the user device 40. The Therefore, the consumer can check his / her energy saving activity point by the user device 40. The calculation unit 13 calculates energy saving activity points in a predetermined period. For example, the calculation unit 13 calculates energy saving activity points in units of one month, and accumulates energy saving activity points in units of one month over one year. To calculate the energy saving activity points for one year. The energy saving activity points calculated for each unit period are stored in the storage unit 12 and presented to the user device 40 as necessary. In addition, the energy-saving activity management apparatus 10 is provided with the communication interface part 17 for communication with the user apparatus 40 provided in the consumer.

  By performing the above-described processing, consumers are motivated to practice energy saving activities by presenting energy saving activity points every month. In addition, when energy saving activity points for one year are accumulated, it becomes possible to manage the emission reduction amount of carbon dioxide on a yearly basis. For example, quantitatively showing the amount of emission reduction relative to the previous year's performance mitigates the effects of monthly fluctuations, and raises awareness of social contribution by grasping the annual amount of emission reduction.

  In short, energy conservation activities are visualized by presenting energy conservation activity points to consumers. In addition, since the degree of contribution to the reduction of the environmental load is shown to the consumer by the energy saving activity point instead of the value of the measured amount of electric power, it becomes easy for the consumer to grasp the degree of social contribution. In addition, consumption and supply are not shown separately, but power consumption and supply are centralized in energy-saving activity points, so consumers can understand the degree of social contribution at a glance. Is possible.

  In addition, if the energy saving activity points given to consumers can be used for part of the funds for purchasing energy saving equipment or lease expenses for energy saving equipment, it is possible to raise awareness of consumers about energy saving activities. Motivation to increase. On the other hand, for the operator of the energy saving activity management apparatus 10, there is an advantage that the sales opportunities for the energy saving equipment increase.

  The reference value storage unit 15 provided in the energy saving activity management apparatus 10 stores not only the reference value used when converting into the above-mentioned energy saving activity points, but also the carbon dioxide emission reference value. As the emission standard value, the specified value or the actual value is used similarly to the standard value.

  For example, when setting the emission standard value for carbon dioxide emissions in one year, the average annual value for one consumer is obtained from the past emissions of multiple consumers, and this average value May be used as the specified value. It is desirable to classify the population for obtaining emission standard values, which are designated values, according to consumer attributes (region, building size, family structure, etc.). Moreover, when calculating | requiring the emission reference value which is a track record value, what is necessary is just to use the emission amount of the last year for every consumer as an emission reference value. Since the emission standard value, which is an actual value, is obtained for each customer, classification based on the attribute of the customer is unnecessary.

  Here, the calculation unit 13 uses the carbon dioxide emission amount obtained for each consumer to calculate the amount of carbon dioxide emission reduction for consumers within a predetermined management range such as a regional unit or a building unit of an apartment house. It is desirable to have a function for calculating the total. The calculating part 13 calculates the sum total of the carbon dioxide emission reduction amount about the consumer in the management range in one of the following procedures.

  When calculating the emission reduction amount for each consumer, regardless of whether the emission standard value is the specified value or the actual value, the sum of the emission reduction amounts becomes the carbon dioxide emission reduction amount in the management range. In other words, the emission reduction amount for each consumer is obtained as the difference between the carbon dioxide emission amount for each consumer and the emission standard value (= emission standard value-emission amount for each consumer). The sum of the differences obtained by subtracting the emission amount for each house is the emission reduction amount in the management range. If the emission amount for each consumer is Qi (i = 1, 2,...) And the emission reference value is B, the emission reduction amount in the management range is obtained as Σ (B−Qi). Here, as the emission reference value B, either a designated value (fixed value) that does not change for each consumer or an actual value that changes for each consumer may be used.

  On the other hand, rather than calculating emission reductions for individual consumers, the emissions for each customer are summed in the management area, and the sum of the emissions for each consumer in the management area and the emission set for this total. The difference from the reference value may be used as the emission reduction amount in the management range. That is, the sum total of the emission amount for each consumer in the management range is obtained, and a value obtained by multiplying the emission reference value for each consumer by the number of cases is used as the emission reference value for the sum of the emission amounts. Now, assuming that the number of customers within the management range is n, and the emission amount for each customer is Qi (i = 1, 2,..., N), and the emission standard value for one customer is B. The emission reduction amount in the management range is obtained as n × B−ΣQi. In this case, a specified value that does not change for each consumer is used as the emission reference value B.

  In addition, when calculating the total amount of carbon dioxide emissions, the total amount of carbon dioxide emissions calculated for each customer is added up within the management range, and the total amount of measurement is added up within the management range. You may convert into.

  In the above example, the emission amount is obtained from the measured amount of electric power measured by the consumer, and the emission reduction amount is obtained using the obtained emission amount. On the other hand, one unit of energy saving activity points can be regarded as corresponding to one unit of emission reduction. Therefore, it is also possible to obtain the energy saving activity points obtained for each consumer for the customers in the management range, treat the energy saving activity points in the same manner as the emission amount, and convert it into the emission reduction amount of carbon dioxide. Here, the energy saving activity point may be used to present to the consumer, and the emission reduction amount of carbon dioxide may be directly calculated from the measured amount of electric power.

  By the way, the amount of carbon dioxide emission reduction for each consumer is small, and for example, it is not an amount that a company purchases carbon dioxide emission rights in the market. However, as described above, there is a possibility that the sum of the emission reduction amounts obtained using the measured amount obtained from the customers within the management range becomes an amount that can be traded in the market. Therefore, the energy saving activity management apparatus 10 collects the carbon dioxide emission reduction amount from the consumer and obtains the sum, so that the operator of the energy saving activity management apparatus 10 performs the energy saving activity by the consumer with the carbon dioxide emission right. It becomes possible to make money by trading.

  In other words, the consideration obtained for the reduction of carbon dioxide emissions from the market will be returned to customers as dividends, and energy saving activity points will be used as funds for purchasing funds and leasing for energy saving equipment. Is possible. The calculated carbon dioxide emission reduction amount can be sold in the emission trading market by receiving certification from the certification body.

  By the way, when the customer is away, the electric load 21 is not used, so that the amount of power consumed is reduced without purchasing power from the power system 31, while large surplus power is generated. Will increase. In such a case, it is possible to evaluate it as an energy-saving activity if only the consumer is seen, but it is also conceivable that the consumer consumes energy in other places. Therefore, it is desirable to evaluate the presence / absence of a person in the consumer and not to regard the increase / decrease in the measured amount of electric power as an energy saving activity in the absence.

  In order to enable this processing, the energy saving activity management device 10 preferably includes a presence / absence monitoring unit 16. The presence / absence monitoring unit 16 determines the presence / absence of a person in the consumer by analyzing the change pattern of the power used in the electrical load 21 in a predetermined period (one day, one week, etc.) from the measurement value acquired by the acquisition unit 11. To do.

  For example, it is possible to determine that a person has operated the electrical load 21 by acquiring a change pattern of the power consumed by the electrical load 21. In this case, when a change in electric power that exceeds a specified value due to the on / off of the electric load 21 is detected, and on (power increase) and off (power decrease) are detected as a pair, between the on and off It is possible to determine that he / she was at home during this period. Alternatively, when the difference between the maximum value and the minimum value of power in one day is equal to or greater than a prescribed threshold value, it can be determined that the user is at home on that day. In the latter case, the home time zone cannot be determined.

  When the presence / absence monitoring unit 16 monitors the home of the customer and the home period can be clearly determined, the calculation unit 13 of the energy saving activity management apparatus 10 determines the home determination result by the presence / absence monitoring unit 16. It is desirable to reflect this in the calculation of energy saving activity points. That is, the calculation unit 13 calculates the energy saving activity points according to whether the presence / absence monitoring unit 16 detects the presence of a person. For example, using the average value of the measured amount of power per unit time (for example, 1 hour) in the home period as the home period, where the person is present, this average value is used as a reference value (specified value or actual value) It is possible to calculate energy saving activity points compared to. Alternatively, if the number of people at home can also be determined, the average value of the measured power per unit time at home is further divided by the number of people at home and compared to the reference value, converted into energy saving activity points. May be. In this case, energy saving activity points per person in the unit time of the home period are required.

  In addition, when the human sensor is arrange | positioned in a consumer, you may acquire the detection result of the presence or absence of a person by the human sensor in the acquisition part 11. FIG. In this configuration, the presence / absence monitoring unit 16 can determine whether the user is at home based on the output of the human sensor. It is also possible to recognize the time zone at home and the place where a person is present at home. Alternatively, it is possible to recognize the number of people at home.

  Furthermore, the calculation unit 13 may obtain the presence rate of the period in which the presence monitoring unit 16 detects the presence of a person in the specified period by using the home determination result by the presence monitoring unit 16. In the case where the presence rate is used, when the presence rate is equal to or higher than the specified value, the energy saving activity points in the specified period may be calculated. For example, assuming that a prescribed period is one day, the existence rate of the day is obtained by obtaining the time of staying at home in one day, and the energy saving activity points may be calculated for the day when the existence rate is equal to or more than a prescribed value. Alternatively, the specified period may be one year, and the number of days in which the home is detected in one year may be the one-year existence rate. Further, the energy saving activity point may be given when the day in which the daily presence rate is equal to or greater than a specified value is equal to or greater than a specified number of days (for example, 300 days) in one year. These numerical values can be changed as appropriate. For example, the number of days at home for a period of one week or one month can be used as the presence rate.

  The operation example of the energy-saving activity management apparatus 10 including the judgment of being at home is collectively shown in FIG. In the operation example shown in FIG. 2, the presence rate is taken into consideration, the measurement unit 11 acquires the measurement value measured by the consumer (S11), and the acquired measurement value is stored in the storage unit 12 (S12). . Here, when it is time to evaluate the energy saving activity point (S13), the presence / absence monitoring unit 16 evaluates the presence / absence of a person in the consumer (S14). The time point at which the energy saving activity point is evaluated is determined, for example, as a unit period of one day, one week, one month, one year, or the like.

  In the home evaluation in step S14, the presence rate in the unit period is evaluated, and if the presence rate is equal to or higher than the specified value (S14: OK), the calculation unit 13 calculates the energy saving activity points. That is, the arithmetic unit 13 compares the power consumption amount with the reference value and converts it into an energy saving activity point (S15), and compares the power supply amount with the reference value and converts it into an energy saving activity point (S16). ). The energy saving activity points obtained by the calculation unit 13 are accumulated (S17). Thereafter, the energy saving activity points calculated this time and the accumulated energy saving activity points are notified to the user device 40 through the presentation unit 14 (S18). In the home evaluation in step S14, if the existence rate in the unit period is less than the specified value (S14: NG), the energy saving activity point is not calculated. In addition, you may convert into the energy-saving activity point as a measured quantity, without distinguishing the consumption and supply amount in step S15, S16.

  As described above, the measured amount of energy resources measured by the consumer is converted into energy saving activity points, and the energy saving activity points are presented to the consumers. Therefore, consumer activities for a low-carbon society, such as the amount of power consumed by the electrical load 21, the amount of power generated by the power generation device 22, and the amount of power stored in the power storage device 23, are centralized as energy saving activity points. Will be shown. Therefore, for consumers, energy conservation activities are presented in an easy-to-understand manner with a single evaluation value called energy conservation activity points, making it easier to understand the effects of energy conservation activities and consequently reducing consumption of depleted energy resources. Motivation for energy saving activities is easier to obtain.

  In the operation example described above, both a consumption amount and a supply amount are used assuming a consumer including the power generation device 22 and the power storage device 23, but the consumer does not include the power generation device 22 or the power storage device 23. Can be converted into energy-saving activity points using only consumption.
