[0012] Embodiment 1. FIG. 1 is a configuration diagram of an energy management system according to Embodiment 1.

[0013] As shown in FIG. 1, the energy management system includes a plurality of facility energy management devices 15 and a regional energy management device 16.

[0014] The plurality of facility energy management devices 15 are respectively provided corresponding to a plurality of facilities within the jurisdiction area 21. The plurality of facility energy management devices 15 manage the supply of energy to one or more jurisdiction bases within the corresponding facilities. Here, the energy is electric energy, thermal energy, etc. The regional energy management device 16 manages the supply of energy to a plurality of facilities within the jurisdiction area 21. Also, managing the supply of energy to the jurisdiction base means managing the supply of energy to each facility provided at the jurisdiction base, that is, managing the consumption of energy by each facility provided at the jurisdiction base.

[0015] In FIG. 1, four facilities A, B, C, and D are provided within the jurisdiction area 21. The four facility energy management devices 15 are respectively provided corresponding to the four facilities A, B, C, and D.

[0016] Each facility has one or more jurisdiction bases. A facility is a unit that collectively controls the supply of energy for one or more jurisdiction bases. For example, Facility A has three jurisdiction bases A1, A2, and A3. For example, Facility B has a plurality of jurisdiction bases including jurisdiction bases B1 and B2. For example, Facility C has a plurality of jurisdiction bases including jurisdiction base C1. For example, Facility D has a plurality of jurisdiction bases including jurisdiction base D1.

[0017] Each jurisdiction base has a space of a certain size. The jurisdiction base is a unit that independently controls the supply of energy to the facilities provided corresponding to the space. For example, the jurisdiction base is a room, an area, a floor, a building, etc. Each jurisdiction base includes, as demand-side facilities, one or more facilities that consume energy. For example, the facilities that consume energy are lighting facilities, ventilation facilities, air conditioning facilities, general facilities, etc. For example, general facilities are facilities that perform determined operations such as elevators and passenger conveyors. These demand-side facilities operate using either or both of electrical energy and thermal energy.

[0018] Each jurisdiction base includes a measurement facility 13 and a measurement sensor 14.

[0019] The measurement facility 13 measures the energy usage status in each demand-side facility. The measurement sensor 14 measures, as information regarding the jurisdiction base, temperature, humidity, size, number of occupants, congestion level, dust amount, CO2 concentration, CO concentration, etc. in the jurisdiction base. Based on the information regarding the jurisdiction base, the staying environment of people in the jurisdiction base is grasped.

[0020] In FIG. 1, the jurisdiction base A1 includes a lighting facility 9, an air conditioning facility 11, a measurement facility 13, and a measurement sensor 14.

[0021] For example, when a constraint occurs in the supply of energy to the jurisdiction area within the jurisdiction area 21 due to a disaster or the like, each facility energy management device 15 transmits information regarding the jurisdiction base to the regional energy management device 16.

[0022] The regional energy management device 16 receives information regarding each jurisdiction base from a plurality of facility energy management devices 15. The regional energy management device 16 determines the priority for each of the plurality of received jurisdiction bases based on the information regarding the plurality of jurisdiction bases. The regional energy management device 16 transmits the determination result of the priority for each jurisdiction base to the facility energy management device 15 that manages the supply of energy to the jurisdiction base.

[0023] Each facility energy management device 15 controls the supply of energy to the jurisdiction base based on the priority determination result received from the regional energy management device 16.

[0024] The facility energy management device 15 includes a transmission / reception unit 15a, a monitoring / control unit 15b, a data collection / accumulation unit 15c, a demand prediction unit 15d, and a data analysis / processing unit 15e.

[0025] The transmission / reception unit 15a has a function of transmitting and receiving information to and from external devices such as the regional energy management device 16.

[0026] The monitoring / control unit 15b has a function of acquiring control / environment information of the demand-side equipment. The monitoring / control unit 15b has a function of controlling the supply of energy to the jurisdiction base (i.e., the consumption of energy at the jurisdiction base) based on the priority determination result received from the regional energy management device 16. Specifically, the monitoring / control unit 15b controls the consumption of energy by the demand-side equipment by controlling the movement of each demand-side equipment provided at the jurisdiction base. The monitoring / control unit 15b corresponds to the control unit in the present disclosure.

[0027] The data collection / accumulation unit 15c has a function of collecting and accumulating information on the use of energy in each demand-side equipment measured by the measurement equipment 13 and information such as the temperature, humidity, area, number of occupants, and congestion level of each jurisdiction base measured by the measurement sensor 14. The information on the temperature, humidity, area, number of occupants, congestion level, etc. of each collected jurisdiction base is transmitted to the regional energy management device 16 by the transmission / reception unit 15a as information regarding the jurisdiction base.

[0028] The demand prediction unit 15d has a function of predicting the demand of each facility based on the information on the use of energy in each demand-side equipment accumulated in the data collection / accumulation unit 15c. The demand prediction unit 15d has a function of calculating the predicted value as the amount of energy required for the jurisdiction base. The information on the calculated required amount of energy is transmitted to the regional energy management device 16 by the transmission / reception unit 15a.

[0029] The data analysis / processing unit 15e has a function of analyzing the control pattern of each facility based on various information stored in the data collection / accumulation unit 15c and the demand corrected by the demand prediction unit 15d.

[0030] The regional energy management device 16 includes a transmission / reception unit 16a, a monitoring / control unit 16b, a data collection / accumulation unit 16c, a power generation prediction unit 16d, a supply available amount determination unit 16e, a priority determination unit 16f, a change power amount calculation unit 16g, a power quality prediction unit 16h, and a control availability determination unit 16i.

[0031] The transmission / reception unit 16a has a function of transmitting and receiving information. For example, the transmission / reception unit 16a has a function of receiving information regarding each jurisdiction base from a plurality of facility energy management devices 15 as demand-side information.

[0032] The monitoring / control unit 16b has a function of acquiring control / environment information of energy supply-side facilities as supply-side information. The monitoring / control unit 16b has a function of controlling energy supply-side facilities. For example, the energy supply-side facilities include a power receiving facility 1, a heavy oil tank 2, a gas pipe 3, an emergency power generation facility 4, a cogeneration system 5, an electric vehicle 6, a storage battery 7, a renewable energy generation facility 8, etc. The monitoring / control unit 16b has a function of controlling the supply of energy from each energy supply-side facility to each facility A, B, C, D within the jurisdiction area 21 by controlling the energy supply-side facilities.

[0033] Here, the power receiving facility 1 receives the supply of power (electrical energy) from the power grid. The heavy oil tank 2 stores heavy oil as fuel. The gas pipe 3 receives the supply of gas. The emergency power generation facility 4 generates electricity using the fuel in the heavy oil tank 2. The cogeneration system 5 generates electricity using the fuel in the heavy oil tank 2 and the gas from the gas pipe 3.

[0034] The electric vehicle 6 and the storage battery 7 perform charging and discharging as energy supply side facilities. The renewable energy generation facility 8 generates renewable energy. For example, the renewable energy generation facility 8 is a solar power generation facility, a wind power generation facility, or the like.

[0035] The data collection and storage unit 16c has a function of collecting and storing various information from the monitoring and control unit 16b and the like. The data collection and storage unit 16c may collect information related to the weather, such as weather and temperature, from an external database in which weather information is recorded.

[0036] The power generation prediction unit 16d has a function of predicting the power generation amount in the jurisdiction area.

[0037] The available supply amount determination unit 16e has a function of determining the amount of energy that can be supplied within the jurisdiction area 21 based on the power generation amount predicted by the power generation prediction unit 16d.

[0038] The priority determination unit 16f has a function of determining the priority for each jurisdiction base point based on the information related to a plurality of jurisdiction base points received from a plurality of facility energy management devices 15 by the transmission and reception unit 16a. The information related to the jurisdiction base point is, as described above, the temperature, humidity, area, number of occupants, congestion level, dust amount, CO2 concentration, CO concentration, etc. of the jurisdiction base point. The priority determination unit 16f determines the priority for each jurisdiction base point based on at least one of these pieces of information.

[0039] For example, when the difference between the temperature of a certain jurisdiction base and a preset comfortable temperature value is greater than the difference between the temperature of another jurisdiction base and the preset comfortable temperature value, the priority determination unit 16f determines that the priority of that jurisdiction base is higher than that of the other jurisdiction bases. For example, when the difference between the humidity of a certain jurisdiction base and a preset comfortable humidity value is greater than the difference between the temperature of another jurisdiction base and the preset comfortable humidity value, the priority determination unit 16f determines that the priority of that jurisdiction base is higher than that of the other jurisdiction bases. For example, when the area of a certain jurisdiction base is larger than the area of another jurisdiction base, the priority determination unit 16f determines that the priority of that jurisdiction base is higher than that of the other jurisdiction bases. For example, when the number of people staying at a certain jurisdiction base is larger than the number of people staying at another jurisdiction base, the priority determination unit 16f determines that the priority of that jurisdiction base is higher than that of the other jurisdiction bases.

[0040] For example, the priority determination unit 16f determines the priority of each jurisdiction base based on information regarding two or more types of jurisdiction bases. For example, the priority determination unit 16f calculates a discomfort index based on the temperature and humidity of the jurisdiction base, and determines that the higher the discomfort index of the jurisdiction base, the higher the priority. For example, the priority determination unit 16f calculates a stay density based on the number of people staying and the area of the jurisdiction base, and determines that the higher the stay density of the jurisdiction base, the higher the priority.

[0041] For example, when the priority determination unit 16f determines the priority based on two or more pieces of information with different units, it converts the data of each piece of information into a score value for standardization, and determines the priority using the converted score value. For example, the priority determination unit 16f determines the priority of each jurisdiction base on the information such as the temperature, humidity, area, and number of staying people of a plurality of jurisdiction bases. In this case, for the temperature of the jurisdiction base, the priority determination unit 16f calculates the deviation value of the temperature of the jurisdiction base after converting the deviation value from the preset comfortable temperature into a score value from 1 to 10. For the humidity of the jurisdiction base, the priority determination unit 16f calculates the deviation value of the humidity of the jurisdiction base after converting the deviation value from the preset comfortable humidity into a score value from 1 to 10. The priority determination unit 16f calculates the congestion degree of the jurisdiction base based on the information of the area and the number of staying people of the jurisdiction base, and calculates the deviation value of the congestion degree of the jurisdiction base after converting the congestion degree into a score value from 1 to 10. For each jurisdiction base, the priority determination unit 16f calculates the total value of the deviation value of the temperature, the deviation value of the humidity, and the deviation value of the occupancy density. The priority determination unit 16f determines that the higher the total value of the deviation value of the temperature, the deviation value of the humidity, and the deviation value of the occupancy density, the higher the priority.

[0042] The variable power amount calculation unit 16g has a function of determining an allowable power amount. The allowable power amount is a power amount that does not exceed the supply capacity capable of maintaining power quality. The power quality is indicated by the degree to which the frequency, voltage, etc. can be stably maintained at preset values.

[0043] The power quality prediction unit 16h has a function of predicting the power quality under preset conditions.

[0044] The control permission determination unit 16i has a function of determining the amount of energy to be permitted for supply to the corresponding jurisdiction base point based on the determination result of the priority for each jurisdiction base point, the information on the amount of energy required for that jurisdiction base point received from the facility energy management device 15, and the information on the amount of energy that can be supplied within that jurisdiction area 21. For example, the control permission determination unit 16i distributes the amount of energy to be permitted for supply to each jurisdiction base point so that, within the range where the total amount of energy permitted for supply to each jurisdiction base point within the jurisdiction area 21 does not exceed the amount of energy that can be supplied as determined by the supply availability determination unit 16e, the higher the priority of the jurisdiction base point, the closer the amount of energy supplied to that jurisdiction base point is to the amount of energy required for that jurisdiction base point. The information on the determined amount of energy to be permitted is transmitted to the corresponding facility energy management device 15.

[0045] Here, the case where the control permission determination unit 16i determines the amount of energy to be permitted for supply to each jurisdiction base point has been described, but the control permission determination unit 16i may also determine the control content to be permitted for the facilities that consume the energy of each jurisdiction base point. Specifically, the control permission determination unit 16i may have a function of determining the control content to be permitted for the facilities that consume the energy of that jurisdiction base point based on the determination result of the priority for each jurisdiction base point, the information on the amount of energy required for that jurisdiction base point received from the facility energy management device 15, and the information on the amount of energy that can be supplied within that jurisdiction area 21 as determined by the supply availability determination unit 16e.

[0046] For example, the control permission determination unit 16i may determine the control content to be permitted for the facilities that consume the energy of each jurisdiction base point so that, within the range where the total amount of energy permitted for supply to each jurisdiction base point within the jurisdiction area 21 does not exceed the amount of energy that can be supplied as determined by the supply availability determination unit 16e, the higher the priority of the jurisdiction base point, the closer the amount of energy consumed by that jurisdiction base point is to the amount of energy required for that jurisdiction base point.

[0047] In this case, the control feasibility determination unit 16i may determine the control content and control feasibility based on the priority calculated by the priority determination unit 16f and the predicted value of the change in power consumption after control so as not to exceed the threshold value.

[0048] For example, for a room with a high priority, the control feasibility determination unit 16i may calculate the power that needs to be increased after determining to improve the facility control. For example, for a room with a low priority, the control feasibility determination unit 16i may calculate the power that can be suppressed after determining to suppress the facility control. The control feasibility determination unit 16i may calculate the total power required by adding the power that needs to be increased, the power that can be suppressed, and the current power. The control feasibility determination unit 16i may determine the overall control feasibility so that the total power required is within the range of the power that can be provided.

[0049] In this way, the plurality of facility energy management devices 15 and the regional energy management device 16 supply power to a plurality of jurisdiction bases in the jurisdiction area 21 in a balanced manner by using the functions of their respective parts.

[0050] Next, the priority table will be described with reference to FIG. 2. FIG. 2 is a diagram showing the priority table of the energy management system in the first embodiment.

[0051] As shown in FIG. 2, in the priority table, information such as "jurisdiction area", "number of occupants", "occupancy density", "temperature", "facility-specific priority", "overall priority", "predicted change in power after control", and "target power change value" is associated.

[0052] The "jurisdiction area" is divided into a plurality of blocks. For example, the plurality of blocks are "Block 1", "Block 2", etc.

[0053] Each block is divided into a plurality of facilities. For example, the plurality of facilities in "Block 1" are "Facility A", "Facility B", etc. For example, the plurality of facilities in "Block 2" are "Facility C", "Facility D", etc.

[0054] Each facility is divided into a plurality of jurisdiction bases. For example, the multiple jurisdiction bases of "Facility A" are "Jurisdiction Base A1", "Jurisdiction Base A2", and "Jurisdiction Base A3". For example, the multiple jurisdiction bases of "Facility B" are "Jurisdiction Base B1", "Jurisdiction Base B2", and "Jurisdiction Base B3". For example, the multiple jurisdiction bases of "Facility C" are "Jurisdiction Base C1", "Jurisdiction Base C2", and "Jurisdiction Base C3". For example, the multiple jurisdiction bases of "Facility D" are "Jurisdiction Base D1", "Jurisdiction Base D2", and "Jurisdiction Base D3".

[0055] "Number of staying people" is information indicating the number of people staying at each jurisdiction base. "Congestion level" is information indicating the density of people staying at each jurisdiction base. "Temperature" is information indicating the temperature of each jurisdiction base. "Facility-specific priority" is information indicating the priority of each jurisdiction base within each facility. "Overall priority" is information indicating the priority of each jurisdiction base within the jurisdiction area. "Predicted power change after control" is information indicating the power change after assuming that the air conditioning equipment 11 of each jurisdiction base is controlled based on the "overall priority". "Target power change value" is information indicating the change value of the target power of each facility after assuming that the air conditioning equipment 11 of each jurisdiction base is controlled based on the "overall priority".

[0056] In FIG. 2, the priority of the "overall priority" is set so that a priority order is assigned to a plurality of jurisdiction bases based on the "staying density" and "temperature" of each jurisdiction base.

[0057] Note that "remaining power of supply equipment" is information indicating the remaining power of the energy supply-side equipment. "Additional control" is information indicating the total of the "predicted power change after control" of each jurisdiction base. As shown in FIG. 2, when the "remaining power of supply equipment" is "+30 kW" and the "additional control" is "+19 kW", the "remaining power of supply equipment" is greater than the "additional control". In this case, the regional energy management device 16 determines that control based on the "overall priority" is possible.

[0058] Next, the outline of the operation of the regional energy management device 16 will be described with reference to FIG. 3. FIG. 3 is a flowchart for explaining the outline of the operation of the regional energy management device of the energy management system in Embodiment 1.

[0059] In step S1, the regional energy management device 16 determines whether there is supply-side information.

[0060] If there is no supply-side information in step S1, the regional energy management device 16 performs the operation of step S2. In step S2, the regional energy management device 16 acquires supply-side information. Then, the regional energy management device 16 performs the operation of step S1.

[0061] If there is supply-side information in step S1, the regional energy management device 16 performs the operation of step S3. In step S3, the regional energy management device 16 determines whether there is demand-side information.

[0062] If there is no demand-side information in step S3, the regional energy management device 16 performs the operation of step S4. In step S4, the regional energy management device 16 acquires demand-side information. Then, the regional energy management device 16 performs the operation of step S3.

[0063] If there is demand-side information in step S3, the regional energy management device 16 performs the operation of step S5. In step S5, the regional energy management device 16 makes an optimal control determination for the jurisdiction area 21. For example, the regional energy management device 16 makes a determination on control to improve comfort by improving the discomfort level indicated by the discomfort index or the like within the allowable power range. Then, the regional energy management device 16 performs the operation of step S6. In step S6, the regional energy management device 16 calculates the target value of the demand power of each facility based on the control content and the amount of change in power associated with the control.

[0064] After that, the regional energy management device 16 performs the operation of step S7. In step S7, the regional energy management device 16 determines whether a completion notice of the change in the target value of the demand power of each facility has been received.

[0065] If the regional energy management device 16 has not received the completion notice of the change in the target demand power of each facility in step S7, the regional energy management device 16 performs the operation of step S7. If the regional energy management device 16 has received the completion notice of the change in the target demand power of each facility in step S7, the regional energy management device 16 performs the operation of step S8.

[0066] The regional energy management device 16 performs the operation of step S8. In step S8, the regional energy management device 16 controls the energy supply side equipment based on the change result of the target demand power of each facility. Then, the regional energy management device 16 ends the operation.

[0067] Next, with reference to FIG. 4, the outline of the operation when the regional energy management device 16 acquires the supply side information will be described. FIG. 4 is a flowchart for explaining the outline of the operation when the regional energy management device of the energy management system in Embodiment 1 acquires the supply side information.

[0068] In step S11, the regional energy management device 16 acquires the power grid status information from the power receiving facility 1.

[0069] After that, the regional energy management device 16 performs the operation of step S12.

[0078] In step S31, the facility energy management device 15 acquires environmental information from the measurement sensor 14. After that, the facility energy management device 15 performs step S32. In step S32, the facility energy management device 15 acquires, as power consumption information, information on the usage status of energy in each demand-side facility from the measurement equipment 13. After that, the facility energy management device 15 performs step S33. In step S33, the facility energy management device 15 acquires control and environmental information from each demand-side facility.

[0079] After that, the facility energy management device 15 performs step S34. In step S34, the facility energy management device 15 predicts and corrects the power demand of each demand-side facility.

[0080] After that, the facility energy management device 15 performs step S35. In step S35, the facility energy management device 15 considers the environmental improvement control pattern. Here, environmental improvement broadly includes improvement of comfort by improving the thermal environment evaluation indices PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied), improvement of the air environment by ventilation and air-conditioning control based on the reference values of air environment measurement, etc. After that, the facility energy management device 15 performs step S36.

[0081] If environmental improvement control is necessary in step S36, the facility energy management device 15 performs step S37. In step S37, the facility energy management device 15 selects the environmental improvement control pattern.

[0082] If environmental improvement control is not necessary in step S36, the facility energy management device 15 performs step S38. In step S38, the facility energy management device 15 does not change the control pattern.

[0083] After step S37 or after step S38, the facility energy management device 15 performs step S39. In step S39, the facility energy management device 15 considers a suppression control pattern.

[0085] Next, with reference to FIG. 7, an outline of the operation when the facility energy management device 15 notifies that the power demand target value has been changed will be described. FIG. 7 is a flowchart for explaining an outline of the operation when the facility energy management device of the energy management system in the first embodiment notifies that the power demand target value has been changed.

[0086] In step S51, the facility energy management device 15 receives a control availability notification for each jurisdiction base. Thereafter, the facility energy management device 15 performs step S52. In step S52, the facility energy management device 15 determines whether a change in the target value of the demand power is requested.

[0087] If a change in the target value of the demand power is requested in step S52, the facility energy management device 15 performs step S53. In step S53, the facility energy management device 15 changes the target value of the demand power.

[0088] If the change of the target value of the demand power is not requested in step S52 or after step S53, the facility energy management device 15 performs the operation of step S54. In step S54, the facility energy management device 15 determines whether it is possible to control each demand-side facility.

[0089] If there is a demand-side facility determined to be controllable in step S54, the facility energy management device 15 performs the operation of step S55. In step S55, the facility energy management device 15 implements the control of the demand-side facility.

[0090] If there is no demand-side facility determined to be controllable in step S54 or after step S55, the facility energy management device 15 performs the operation of step S56. In step S56, the facility energy management device 15 completes the change of the target value of the power demand control. After that, the facility energy management device 15 performs the operation of step S57. In step S57, the facility energy management device 15 notifies the regional energy management device 16 that the target value of the power demand has been changed. After that, the facility energy management device 15 ends the operation.

[0091] According to the first embodiment described above, the regional energy management device 16 receives information about each jurisdiction base from a plurality of facility energy management devices 15. The regional energy management device 16 determines the priority for each of the plurality of received jurisdiction bases based on the received information. The regional energy management device 16 transmits the determination result of the priority for each jurisdiction base to the facility energy management device 15 that manages the energy supply to the jurisdiction base. Each facility energy management device 15 controls the energy supply to the jurisdiction base based on the determination result of the priority received from the regional energy management device 16. Therefore, even when the power supply amount in the jurisdiction area 21 is restricted during a disaster or the like, it is possible to supply power to a plurality of jurisdiction bases in the jurisdiction area 21 in a balanced manner.

[0092] In addition, the regional energy management device 16 determines the amount of energy to be permitted for supply to the jurisdiction base on the basis of the priority determination result for each jurisdiction base, the information on the amount of energy required for that jurisdiction base received from the facility energy management device 15, and the information on the amount of energy that can be supplied within that jurisdiction area 21. For this reason, it is possible to appropriately supply power to each demand-side facility at each jurisdiction base.

[0093] In addition, the regional energy management device 16 determines the control content to be permitted for the facilities that consume the energy of that jurisdiction base on the basis of the priority determination result for each jurisdiction base, the information on the amount of energy required for that jurisdiction base received from the facility energy management device 15, and the information on the amount of energy that can be supplied within that jurisdiction area 21 determined by the supplyable amount determination unit 16e. For this reason, it is possible to appropriately supply power to each demand-side facility at each jurisdiction base.

[0094] In addition, the regional energy management device 16 may determine the priority of the jurisdiction base on the basis of at least one piece of information among the temperature, humidity, area, and number of occupants of the jurisdiction base. In this case, the priority of each jurisdiction base can be appropriately set.

[0095] In addition, the regional energy management device 16 may determine the priority for the jurisdiction base on the basis of a first evaluation value obtained by evaluating the comfort level of each of the plurality of jurisdiction bases and a second evaluation value obtained by evaluating the degree of influence on the people staying at each of the plurality of jurisdiction bases. For example, the discomfort index may be adopted as the comfort level of each of the plurality of jurisdiction bases, and the first evaluation value may be calculated. For example, the degree of influence on the people staying at each of the plurality of jurisdiction bases may be calculated by adopting the number of occupants and the degree of congestion of the facility and the jurisdiction base, and the second evaluation value may be calculated. In this case, the priority of each jurisdiction base can be appropriately set.

[0096] In addition, when constraints occur in the supply of energy to multiple facilities, the regional energy management device 16 may select a jurisdiction base recommended as a stay destination from among multiple jurisdiction bases based on the comfort level at the multiple jurisdiction bases, the number of occupants, information on the amount of electrical energy required for environmental improvement, and the impact of the supply of the amount of electrical energy required for environmental improvement on power quality. Thereafter, the regional energy management device 16 may transmit information indicating the selected jurisdiction base to the multiple facility energy management devices. At this time, the multiple facility energy management devices 15 may notify the occupants of the facility of information including the information indicating the selected jurisdiction base. For example, the multiple facility energy management devices 15 may notify the information such as "the jurisdiction base of facility ** is relatively comfortable / the jurisdiction base of facility *** is not recommended" by display or voice output. In this case, it is possible to suppress the concentration of disaster victims at some bases during a disaster.

[0097] In addition, priority may be set for multiple blocks. For example, the priority of blocks with shelters and medical facilities may be increased, and then the overall priority of the region may be set.

[0098] In addition, in the priority table, the overall priority of the jurisdiction area 21 may be set in consideration of the brightness of the lighting equipment 9, the presence or absence of an elevator, the presence or absence of a passenger conveyor, etc.

[0099] In addition, in order to ensure fairness, the overall priority of the jurisdiction area 21 may be set in consideration of the presence or absence of the previous improvement control of each demand-side facility.

[0100] In addition, for the air conditioning equipment 11, the overall priority of the jurisdiction area 21 may be set in consideration of the amount of electric power required to change the temperature by 1 degree.

[0101] Next, an example of the facility energy management device 15 will be described with reference to FIG. 8. FIG. 8 is a hardware configuration diagram of the facility energy management device in Embodiment 1.

[0103] When the processing circuit includes at least one processor 100a and at least one memory 100b, each function of the facility energy management device 15 is realized by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. At least one of the software and the firmware is stored in at least one memory 100b. The at least one processor 100a reads and executes the program stored in the at least one memory 100b to realize each function of the facility energy management device 15. The at least one processor 100a is also referred to as a central processing unit, a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. For example, the at least one memory 100b is a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, or a DVD.

[0104] When the processing circuit includes at least one dedicated hardware 200, the processing circuit is realized by, for example, a single circuit, a composite circuit, a programmed processor, a parallel-programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the facility energy management device 15 is realized by the processing circuit respectively. For example, each function of the facility energy management device 15 is realized by the processing circuit collectively.

[0105] Regarding each function of the facility energy management device 15, part of it may be realized by dedicated hardware 200, and the other part may be realized by software or firmware. For example, regarding the function of the monitoring and control unit 15b, it may be realized by a processing circuit as dedicated hardware 200, and regarding functions other than the function of the monitoring and control unit 15b, at least one processor 100a may read and execute a program stored in at least one memory 100b to realize it.

[0106] In this way, the processing circuit realizes each function of the facility energy management device with hardware 200, software, firmware, or a combination thereof.
