[0016] The following describes an energy consumption performance calculation support system 1 according to a first embodiment of the present invention. The energy consumption performance calculation support system 1 supports calculation of a predicted value of the energy consumption performance of a building.

[0017] In this embodiment, the building for which calculation support for energy consumption performance is provided is assumed to be a non-residential building. Examples of uses of the building include an office or a store (retail store). The building is in the design stage before specifications for equipment and thermal insulation performance are determined. Hereinafter, the building for which calculation support for energy consumption performance is provided may be referred to as the "building to be designed."

[0018] In this embodiment, the energy consumption performance calculation support system 1 uses the Building Energy Efficiency Index (BEI) as an index of energy saving performance for which calculation is supported. The BEI is calculated by dividing the energy consumption (primary energy consumption) of a target building by a standard energy consumption (standard primary energy consumption). The smaller the BEI value, the higher the energy saving performance of the building.

[0019] Methods for predicting the BEI include the "standard input method," which calculates the BEI value using information on all rooms to be evaluated (such as the use and area of ​​each room), and the "model building method," which calculates the BEI value by reflecting the specifications of the equipment and facilities that will actually be installed in a model building that assumes the shape and room use for each building use.The standard input method calculates the BEI value based on the actual information for each room, allowing for a more precise evaluation than the model building method.

[0020] When calculating the BEI value using the standard input method, it is possible to carry out calculations (such as simulations) using a calculation program (such as an "Energy Consumption Performance Calculation Program (Non-Residential Version)") for calculating energy consumption performance in accordance with, for example, the "Act on Improvement of Energy Consumption Performance of Buildings (Building Energy Conservation Act)." The calculation program calculates a predicted BEI value based on information about each room in the building (such as information about the purpose, area, and facilities of each room in the building).

[0021] In the method using the calculation program, calculations are performed based on information entered into multiple fields on an input sheet. The tables shown in Figures 2 to 5 show examples of multiple sheets (basic information input sheet, etc.) included in the input sheet. Note that the above tables show only a portion of the input sheet.

[0022] The "Basic Information Input Sheet" shown in Figure 3 is used to input basic information about a building. The items on the basic information input sheet include "construction site," "area classification," "number of floors," and "total floor area." Information about the location where the building will be constructed (location information at the city / town / village level) is input in "construction site." Information about the area classification (energy saving standard area classification, annual solar radiation area classification) that includes the "construction site" is input in "area classification." Information about the number of floors of the building is input in "number of floors." Information about the total floor area of ​​the building is input in "total floor area."

If the envelope is an exterior wall, information indicating the direction (north, east, west, or south) is input into "Orientation." If the envelope is a floor, "shade" is input into "Orientation." If the envelope is a roof, "horizontal" is input into "Orientation." "Exterior Wall Name" is used to input information indicating the name of the exterior wall.

Information indicating the presence or absence of a high-efficiency motor, inverter, and airflow control is entered in "High-Efficiency Motor," "Inverter," and "Airflow Control."

[0026] The "Lighting Input Sheet" is used to input information about lighting. The fields on the "Lighting Input Sheet" include "Room Name," "Area," "Rated Power Consumption," "Number of Units," "Occupancy Detection Control," "Brightness Detection Control," "Time Schedule Control," and "Initial Illuminance Correction Control." The "Room Name" and "Area" fields are used to input information indicating the name and area of ​​the room where the lighting will be installed. The "Rated Power Consumption" and "Number of Units" fields are used to input information indicating the rated power consumption and number of lighting devices. The "Occupancy Detection Control" field is used to input information indicating whether or not occupancy detection control (lighting control using a motion sensor, etc.) is enabled. The "Brightness Detection Control" field is used to input information indicating whether or not brightness detection control (lighting control using a brightness sensor, etc.) is enabled. The "Time Schedule Control" field is used to input information indicating whether or not time schedule control (lighting control based on a preset time) is enabled. The "Initial Illuminance Correction Control" field is used to input information indicating whether or not initial illuminance correction control (control to correct the illuminance (initial illuminance) of newly installed lighting devices) is enabled.

[0027] The "Hot Water Supply Input Sheet" shown in Figure 5 is used to input information related to hot water supply. The items on the "Hot Water Supply Input Sheet" include "Room Name" and "Water-Saving Device." Information indicating the name of the room in which the hot water supply device is installed is input in "Room Name."

[0029] The "Elevator Input Sheet" is where information about the elevator is entered. The "Elevator Input Sheet" includes "Room Name," "Equipment Name," "Speed," and "Speed ​​Control Method." Information indicating the location where the elevator is installed is entered in "Room Name." Information indicating the elevator name, speed, and speed control method is entered in "Equipment Name," "Speed," and "Speed ​​Control Method."

[0030] The "Solar Power Generation System Input Sheet" is used to input information about the solar power generation system. The "Solar Power Generation System Input Sheet" includes fields such as "Solar Power Generation System Name," "Panel Azimuth Angle," "Panel Tilt Angle," and "System Capacity." Information indicating the name of the solar power generation system is input in "Solar Power Generation System Name." Information indicating the azimuth angle and tilt angle of the solar panels is input in "Panel Azimuth Angle" and "Panel Tilt Angle." Information indicating the system capacity of the solar power generation system is input in "System Capacity."

[0031] The above is a description of each item on the input sheet. Note that the above description is an example, and the items included in the input sheet are not limited to those described above.

[0032] The calculation results from the above calculation program are output as an evaluation sheet as shown in Figure 6. The evaluation sheet contains the predicted value (determination result) of the BEI based on the contents of the input sheet and the energy consumption performance for each specification of the facility equipment. Although not shown in the illustration, the evaluation sheet also contains information on each item on the input sheet (see Figures 3 to 5). Note that the above explanation is an example, and the items included in the evaluation sheet are not limited to those mentioned above.

[0033] As described above, a target value (target value) is set for the energy consumption performance of a building indicated by the BEI. In this embodiment, the target value for the energy consumption performance of a building is the standard value for ZEB (Net Zero Energy Building). Here, "ZEB" refers to a building whose annual primary energy consumption is zero or negative.

[0034] Here, it is expected that the work of performing calculations using the calculation program of the standard input method and obtaining calculation results that reach the target value will be a heavy burden. Specifically, performing calculations using the calculation program of the standard input method requires entering information for many items (e.g., 180 or more) into an input sheet. If the calculation results using the calculation program do not reach the target value, the input contents of any of the many items (e.g., items such as insulation performance or equipment specifications) must be appropriately changed and the calculation must be performed again. In this case, the user will have to repeatedly change the input contents and perform the calculation until the calculation result reaches the target value, without knowing which items need to be changed in order for the calculation result of energy consumption performance to reach the target value. As a result, the work burden required to obtain calculation results that reach the target value is heavy.

[0035] The energy consumption performance calculation support system 1 shown in FIG. 1 can output ZEB specification information 4 as support for calculating the energy consumption performance (predicted BEI value) of a building to be designed using a calculation program based on the standard input method (see FIGS. 2 and 9). Here, the ZEB specification information 4 is information indicating specifications for equipment and insulation performance (ZEB specifications) that can achieve the target ZEB standard. The contents of the ZEB specification information 4 will be described later. The energy consumption performance calculation support system 1 includes a control device 10 and an external server 20.

[0036] The control device 10 is capable of processing various types of information. A general personal computer, a server, or the like can be used as the control device 10. The control device 10 is managed, for example, by a business operator that designs buildings. The control device 10 includes a memory unit 11, a control unit 12, a communication unit 13, an input unit 14, and a display unit 15.

[0037] The storage unit 11 stores various programs and various acquired information, and is configured with a HDD, RAM, ROM, etc.

[0038] The control unit 12 executes the programs stored in the storage unit 11. The control unit 12 is configured by a CPU.

[0039] The communication unit 13 is capable of communicating with external devices. The communication unit 13 can exchange information with external devices via various communication means such as the Internet. Communication using the communication unit 13 enables access to a database of an external server 20, which will be described later.

[0040] The input unit 14 is used to input various types of information and is composed of a keyboard, a mouse, and the like.

[0041] The display unit 15 displays various types of information and is configured by, for example, a liquid crystal display.

[0042] The external server 20 is a control means different from the control device 10, and is a control device capable of storing and calculating various types of information. The external server 20 is mainly composed of an arithmetic processing unit such as a CPU, storage devices such as RAM and ROM, and input / output devices. The external server 20 is capable of communicating with the control device 10.

[0043] The external server 20 stores a plurality of building evaluation sheets calculated in the past using a calculation program. The external server 20 also includes a database in which registered information 3, which is data based on the evaluation sheets calculated in the past and is data necessary for outputting the ZEB specification information 4, is registered. The registered information 3 will be described in detail later.

[0044] 2, the energy consumption performance calculation support system 1 can output ZEB specification information 4 based on input information 2 input by a user and registered information 3 registered in a database. The input information 2, registered information 3, and ZEB specification information 4 will be explained below.

[0045] The input information 2 is information about the building to be designed that is input by the user to the control device 10. The input information 2 is input, for example, by the input unit 14. The input information 2 includes first design information 2a and first energy consumption information 2b.

[0046] The first design information 2a is information about the basic design details of the building to be designed. The first design information 2a includes information about the "construction site," "number of floors," and "total floor area" of the building. Note that the "construction site," "number of floors," and "total floor area" of the first design information 2a are generally similar to the "construction site," "number of floors," and "total floor area" of the "basic information input sheet" shown in Figure 3, so explanations will be omitted.

[0047] The first energy consumption information 2b is information relating to the target energy consumption of the building to be designed. The first energy consumption information 2b includes a "BEI value" and a "primary energy consumption per unit area." The "BEI value" is a target value of the energy consumption indicator (BEI) that is a target of the building to be designed. In this embodiment, a value that can achieve the ZEB standard is set as the "BEI value." The "primary energy consumption per unit area" is a value of the primary energy consumption per unit area of ​​the building to be designed, which is set based on the "BEI value."

[0048] The registered information 3 is information registered in the database of the external server 20. The registered information 3 is created based on an evaluation sheet of a building (hereinafter referred to as a "designed building") whose energy consumption performance has been calculated in the past using a calculation program. The registered information 3 includes second design information 3a, second energy consumption information 3b, and calculation information 3c.

[0049] The second design information 3a is information about the basic design details of a building that has already been designed. Similar to the first design information 2a, the second design information 3a includes information about the "construction site," "number of floors," and "total floor area" of the building that has already been designed. The second design information 3a uses information from the input sheet included in the evaluation sheet for the building that has already been designed (see FIG. 3).

[0050] The second energy consumption information 3b is information relating to the target energy consumption of a designed building. The second energy consumption information 3b includes the "BEI value" and the "primary energy consumption per unit area." The "BEI value" is the energy consumption indicator (BEI) value calculated for the designed building. The "primary energy consumption per unit area" is the value of the primary energy consumption per unit area of ​​the designed building that is set based on the "BEI value." The second energy consumption information 3b uses information from the evaluation sheet for the designed building.

[0051] The calculation information 3c is information that has a large impact on the energy consumption index (BEI) from among the information included in the evaluation sheet of the designed building, converted into information that can be used to output the ZEB specification information 4. Here, "conversion" refers to information processing in which predetermined processing is performed on the information in the evaluation sheet to generate the calculation information 3c, and the specific content of the information processing is set for each specification as described below. The information processing for generating the calculation information 3c can be executed by an external server 20. As shown in FIG. 2, the calculation information 3c includes "insulation specification," "heat-shielding specification," "air-conditioning specification," "ventilation specification," "lighting specification," "hot water supply specification," "elevator specification," and "photovoltaic power generation specification." The content of the information processing for each specification will be explained below with reference to FIG. 7.

[0052] "Insulation specifications" are information indicating the insulation specifications for the exterior envelope (exterior walls, floors, and roofs) and are converted from information on evaluation sheets for pre-designed buildings (such as the "Exterior Envelope Specifications Input Sheet" shown in Figure 4). "Insulation specifications" include "exterior wall heat transfer coefficient." The "exterior wall heat transfer coefficient" is obtained by extracting the heat transfer coefficient value of the largest exterior envelope area among the items (exterior wall items) for which the "orientation" is not set to "horizontal" or "shade" in the "Exterior Envelope Specifications Input Sheet" shown in Figure 4. The heat transfer coefficient value can also be obtained using information other than the "Exterior Envelope Specifications Input Sheet" from the evaluation sheet. Instead of or in addition to the "exterior wall heat transfer coefficient," the heat transfer coefficient values ​​of the floor, roof, and windows can also be extracted as "insulation specifications."

[0053] "Heat shielding specifications" is information indicating the heat shielding specifications of windows, and is converted from information on evaluation sheets for designed buildings (such as the "Outer Skin Specifications Input Sheet" shown in Figure 4). "Heat shielding specifications" includes "window solar heat gain coefficient." "Window solar heat gain coefficient" is obtained by extracting the value of the solar heat gain coefficient of the window installed in the exterior wall with the largest outer skin area for each item on the "Outer Skin Specifications Input Sheet" shown in Figure 4. The value of the solar heat gain coefficient can also be a value obtained using information from the evaluation sheet other than the "Outer Skin Specifications Input Sheet."

[0054] "Air conditioning specifications" is information indicating specifications related to air conditioning, and is converted from information on the evaluation sheet for a designed building ("heat source input sheet" shown in Figure 4). "Air conditioning specifications" includes "heat source COP." "Heat source COP" is obtained by extracting the value obtained by dividing the rated heat source capacity ("rated cooling capacity" or "rated heating capacity") by the rated energy consumption ("rated energy consumption (cold)" or "rated energy consumption (heat)") for the air conditioning zone with the largest room area for each item on the "heat source input sheet" shown in Figure 4.

[0055] "Ventilation specifications" is information indicating specifications related to ventilation, and is a conversion of information from the evaluation sheet for a designed building ("Intake and Exhaust Fan Input Sheet" shown in Figure 4). "Ventilation specifications" includes "air flow control." "Air flow control" can be obtained by extracting information on whether or not air flow control is performed for the ventilation equipment in rooms with a large room area ratio for each item on the "Intake and Exhaust Fan Input Sheet" shown in Figure 4. Note that instead of or in addition to "air flow control," it is also possible to extract information on whether or not other controls are performed for the ventilation equipment as "ventilation specifications."

[0056] "Lighting specifications" is information indicating specifications related to lighting, and is a converted version of the information on the evaluation sheet for a designed building ("Lighting Input Sheet" shown in Figure 4). "Lighting specifications" includes "brightness detection control." "Brightness detection control" can be obtained by extracting information on the presence or absence of brightness detection control for lighting in rooms with a large indoor area ratio from each item on the "Lighting Input Sheet" shown in Figure 4. Note that it is also possible to extract information on the presence or absence of other lighting controls as "lighting specifications" instead of, or in addition to, "brightness detection control."

[0057] "Hot water specifications" is information indicating specifications related to hot water supply, and is converted from information on the evaluation sheets for a designed building (the "Hot Water Input Sheet" and "Hot Water Equipment Sheet" shown in Figure 5). "Hot water specifications" includes "heat source efficiency." "Heat source efficiency" is obtained by extracting the value of the heat source efficiency of the hot water equipment in rooms with a large room area ratio for each item on the "Hot Water Equipment Sheet" shown in Figure 5. Note that instead of or in addition to "heat source efficiency," it is also possible to extract information on "water-saving appliances" and "pipe insulation specifications" as "hot water specifications."

[0058] "Elevator specifications" is information indicating the specifications of elevators, and is converted from information on the evaluation sheet for a designed building ("Elevator Input Sheet" shown in Figure 5). "Elevator specifications" includes "speed control method." "Speed ​​control method" is obtained by extracting the most frequently occurring value for each item on the "Elevator Input Sheet" shown in Figure 5. Note that it is also possible to extract "speed" information as "elevator specifications" instead of, or in addition to, "speed control method."

[0059] "Photovoltaic power generation specifications" is information indicating specifications related to photovoltaic power generation, and is obtained by converting information from the evaluation sheet for a designed building ("Photovoltaic Power Generation System Input Sheet" shown in Figure 5). "Photovoltaic power generation specifications" includes "panel azimuth angle." "Panel azimuth angle" is obtained by extracting the most frequently occurring value from each item in the "Photovoltaic Power Generation System Input Sheet" shown in Figure 5. Note that it is also possible to extract information on "panel tilt angle" or "system capacity" as "photovoltaic power generation specifications" instead of, or in addition to, "panel azimuth angle."

[0060] The external server 20 registers, in a database, registration information 3 that combines the second design information 3a, the second energy consumption information 3b, and the calculation information 3c. The database registers registration information 3 for a plurality of buildings.

[0061] 8, the following describes the flow of processing when the energy consumption performance calculation support system 1 outputs the ZEB specification information 4. The control device 10 or the external server 20 of the energy consumption performance calculation support system 1 executes a database process (step S10), an input information acquisition process (step S20), a search process (step S30), and an output process (step S40).

[0062] The database creation process (step S10) is a process of registering the registration information 3 based on the evaluation sheet for the already designed building in a database of the external server 20. In the database creation process, as described above, the external server 20 registers the registration information 3, which is a combination of the second design information 3a, the second energy consumption information 3b, and the calculation information 3c, in the database. At this time, the external server 20 performs information processing to convert the information in the evaluation sheet and generate the calculation information 3c as described above (see FIG. 7).

[0063] The input information acquisition process (step S20) is a process for acquiring input information 2. In the input information acquisition process, the control device 10 acquires the input information 2 that the user inputs using the input unit 14 (see FIG. 2). The input using the input unit 14 inputs the minimum amount of information about the building to be designed into the control device 10. In this embodiment, all of the information in the input information 2 (first design information 2a and first energy consumption information 2b) is input to the control device 10. Note that, as will be described later, even if the first design information 2a of the input information 2 is insufficient, it is possible to output the ZEB specification information 4.

[0064] The search process (step S30) is a process for searching, based on the input information 2, a plurality of pieces of registered information 3 registered in the database for registered information 3 corresponding to the input information 2 (see FIG. 2). The search process is executed by the control device 10. Specifically, the control device 10 searches, from the plurality of pieces of registered information 3, for registered information 3 having second design information 3a and second energy consumption information 3b that correspond to (are similar to) the first design information 2a and first energy consumption information 2b included in the input information 2.

[0065] In the search process, the control device 10 extracts, from the registered information 3 in the database, registered information 3 having information (second design information 3a and second energy consumption information 3b) that roughly matches a plurality of pieces of information (five items of information in this embodiment) included in the input information 2 (first design information 2a and first energy consumption information 2b), as registered information 3 of buildings similar to the building to be designed (similar buildings). As a method for determining the similarity of the above buildings, for example, a method can be used in which plots of multiple buildings extracted based on the above five items of information (input information 2) are displayed on coordinate axes, an approximation line is drawn, and similar buildings are determined using the approximation line (for example, by extracting buildings near the approximation line). Note that the method for determining similar buildings is not limited to the above example, and various determination methods can be used, such as a method using a learning model generated by machine learning.

[0066] The output process (step S40) is a process of outputting the calculation information 3c of the registration information 3 of similar buildings found in the search process as ZEB specification information 4. FIG. 9 shows an example of the output result of the output process. As shown in FIG. 9, the ZEB specification information 4 of the output result includes information on the specifications of equipment and insulation performance that can achieve ZEB, such as "insulation specification," "heat shielding specification," "air conditioning specification," "ventilation specification," "lighting specification," "hot water supply specification," "elevator specification," and "photovoltaic power generation specification." The output result shown in FIG. 9 also includes design information (first design information 2a) of the building to be designed, such as the construction site, number of floors, and total floor area, and the target value of the BEI (first energy consumption information 2b) of the building to be designed. Note that the ZEB specification information 4 output in the output process is not limited to the example shown in FIG. 9. The ZEB specification information 4 can be changed as appropriate depending on the information included in the calculation information 3c.

[0067] The above describes the processing executed by the energy consumption performance calculation support system 1. With the energy consumption performance calculation support system 1, a user can ascertain the specifications of the equipment and insulation performance (ZEB specification information 4) that will enable the building to meet the ZEB standards, simply by inputting input information 2, which is basic information about the building to be designed. By determining the specifications of the equipment and insulation performance based on the ZEB specification information 4, the burden of inputting information into each item on the input sheet of the calculation program can be reduced when calculating the energy performance of the building to be designed.

[0068] The processes executed by the energy consumption performance calculation support system 1 are not limited to the above-described aspects, and the content of each process can be changed as appropriate. For example, in the above example, in the search process (step S30), if five items of information included in the input information 2 (first design information 2a, first energy consumption information 2b) roughly match five items of information included in the registered information 3 in the database, it is determined that the pieces of information correspond, but the present invention is not limited to the above-described example. For example, even if some of the five items of information do not match (roughly match), it is also possible to determine that the pieces of information correspond.

[0069] Specifically, in the search process, if the registration information 3 of the database does not contain information that matches the "construction site" information contained in the first design information 2a, the control device 10 converts the "construction site" information contained in the first design information 2a into information on the "area division" that includes the "construction site," and can determine that second design information 3a having information on the "construction site" included in the above-mentioned "area division" corresponds to the first design information 2a. According to the above configuration, even if the database does not contain enough information on the "construction site" contained in the first design information 2a, the search can be supplemented by second design information 3a that includes information on other "construction sites" that share the same area division as the above-mentioned "construction site."

[0070] Furthermore, in the search process, the control device 10 can search for registered information 3 even when the database does not contain registered information 3 having second design information 3a corresponding to the first design information 2a, for example, when the input information 2 is short of first design information 2a or when the database is short of second design information 3a. Specifically, in the search process, the control device 10 can search for registered information 3 having second energy consumption information 3b whose "primary energy consumption per unit area" is equivalent to the "primary energy consumption per unit area" contained in the first energy consumption information 2b, among the multiple pieces of registered information 3 registered in the database. For example, when the ratio of the difference between the "primary energy consumption per unit area" of each piece of energy consumption information to the "primary energy consumption per unit area" of the first energy consumption information 2b is within a predetermined range (for example, approximately ±5%), the control device 10 can determine that the "primary energy consumption per unit area" of each piece of energy consumption information is equivalent. According to the above configuration, even if the first design information 2a of the input information 2 and the second design information 3a of the registered information 3 do not correspond to each other, the search can be complemented by searching for registered information 3 whose "primary energy consumption per unit area" is equivalent to the "primary energy consumption per unit area" in the input information 2.

[0071] As described above, the energy consumption performance calculation support system 1 according to one embodiment of the present invention: an information input unit (control device 10) to which input information including first design information 2a, which is information on the design details of a first building to be designed, and first energy consumption information 2b, which is information on the target energy consumption of the first building, is input (step S20); an information conversion unit (external server 20) that converts specification information (evaluation sheet) that is information on specifications of equipment and thermal insulation performance of a second building that has already been designed and is different from the first building into calculation information 3c that can be used to support calculation of the energy consumption performance of the first building (step S10); an information registration unit (external server 20) that registers (step S10) a plurality of pieces of registration information 3, each of which combines second design information 3a, which is information about the design content of the second building, second energy consumption information 3b, which is information about the energy consumption performance of the second building, and the calculation information 3c; a search unit (control device 10) that searches for registered information 3 having the second design information 3a and the second energy consumption information 3b corresponding to the first design information 2a and the first energy consumption information 2b from among the plurality of registered information 3 registered in the information registration unit (step S30); an output unit (control device 10) that outputs the calculation information 3c of the registered information 3 searched by the search unit (step S40); It is equipped with the following.

[0072] This configuration reduces the burden of calculating the energy consumption performance of a building. In other words, it is possible to determine the specifications of equipment and insulation performance that will enable the building to achieve its energy consumption target (ZEB standard) for the building being designed. This reduces the burden of determining the specifications of equipment and insulation performance for calculating energy consumption performance.

[0073] In addition, the first design information 2a and the second design information 3a include: The information includes at least one of the following: construction site, number of floors, and total floor area.

[0074] With this configuration, by inputting basic design information for a building, it is possible to grasp the specifications of the equipment and thermal insulation performance that can achieve the energy consumption target.

[0075] In addition, the first design information 2a and the second design information 3a include: At a minimum, information on the construction site is included.

[0076] With this configuration, even if the information on the construction site included in the first design information 2a is insufficient in the information registration section, the search can be supplemented with information on other construction sites that share the same area classification as the above construction site.

[0077] In addition, the first energy consumption information 2b and the second energy consumption information 3b include: The information is contained in the amount of primary energy consumption per unit area, The search unit (control device 10) If the registration information 3 having the second design information 3a corresponding to the first design information 2a is not registered in the information registration unit (external server 20), Among the multiple pieces of registered information 3 registered in the information registration unit (external server 20), a search is made for registered information 3 that has the second energy consumption information 3b whose primary energy consumption per unit area is equivalent to the primary energy consumption per unit area included in the first energy consumption information 2b.

[0078] With this configuration, even if registered information 3 having second design information 3a corresponding to first design information 2a is not registered in the information registration section, the search can be complemented by searching for registered information 3 having a primary energy consumption per unit area equivalent to the primary energy consumption per unit area in input information 2.
