[0002] BACKGROUND ART Conventionally, systems for evaluating the performance of buildings have been known. Patent Document 1 discloses a building performance evaluation system that calculates the thermal insulation performance of a building based on the structure of the building.

[0003] JP 2024-15808 A

[0004] Conventional building performance evaluation systems are used to evaluate the performance of a building after its structure has been determined. Therefore, even with the conventional building performance evaluation systems, it is not possible to determine what components of a building should be used to achieve the desired performance.

[0005] The present invention has been made in consideration of these points, and aims to make it possible to determine the types of components that make up a building in consideration of the performance of the building.

[0006] An information processing device of a first aspect of the present invention includes a reception unit that receives a selection of a wall type to be used from a plurality of candidate wall types, which are types of walls that can be installed in a building; a performance identification unit that identifies the performance of the building based on the wall type selected by the reception unit; and an output unit that outputs performance information indicating the performance of the building identified by the performance identification unit.

[0007] The wall types may include a painted wall having a reinforcing coating layer and an unpainted wall not having the reinforcing coating layer. The wall types may include a plurality of types that differ in at least one of the type of paint forming the reinforcing coating layer, the coating area, and the coating thickness.

[0012] The reception unit may receive the thickness of the reinforcing coating layer formed on the wall as the wall type, and the performance identification unit may determine, based on the thickness of the reinforcing coating layer received by the reception unit, whether to treat the wall as a non-structural wall and identify the performance of the building, or to treat the wall as a structural wall and identify the performance of the building.

[0015] The performance identification unit may identify the amount of carbon dioxide reduction based on the difference between the amount of carbon dioxide emitted by the building when a reference wall is used and the amount of carbon dioxide emitted by the building when a wall of the wall type selected by the reception unit is used, and may identify the cost taking carbon credits into account by subtracting an amount corresponding to the carbon credits corresponding to the identified amount of carbon dioxide reduction from the cost of the building identified based on the cost of the wall of the wall type selected by the reception unit.

[0016] The information processing device may further have a memory unit that stores wall information indicating the wall type and the materials contained in the wall, and emission information indicating the relationship between the materials and the amount of carbon dioxide emission, and the performance identification unit may identify the amount of each of the multiple materials used in the building based on the materials contained in the wall type selected by the reception unit and the number of walls of each of the multiple wall types used in the building, and identify the amount of carbon dioxide emitted by the multiple materials as the performance based on the emission information.

[0017] The information processing device may further have a memory unit that stores the wall type in association with the fire resistance performance of individual walls of that wall type, and the performance identification unit may identify the fire resistance performance of the building based on the wall type selected by the reception unit, the number of walls of each of the one or more wall types used in the building, and the fire resistance performance of individual walls corresponding to the wall type.

[0019] An information processing device of a second aspect of the present invention includes a reception unit that receives specification of performance conditions required for a building, a performance identification unit that identifies the performance of the building for each combination of wall types that can be used as multiple walls used in the building, and an output unit that outputs information indicating the wall types for which the performance of the building identified by the performance identification unit satisfies the performance conditions specified by the reception unit.

[0023] According to the present invention, it is possible to determine the types of components that make up a building in consideration of the performance of the building.

FIG. 3 is a diagram showing an example of wall performance data. FIG. 4 is a diagram showing an example of an exterior view and floor plan of a building displayed on an information terminal 2. FIG. 5 is an example of a schematic diagram of a plurality of walls with different coating patterns. FIG. 6 is a diagram showing an example of performance information output by an output unit 133. FIG. 7 is a diagram showing the processing flow in the information processing device 1.

[0025] First Embodiment [Outline of Performance Analysis System S] Fig. 1 is a diagram for explaining an outline of the performance analysis system S. The performance analysis system S is a system that enables a user U to understand how the performance of a building changes by changing the types of components (e.g., wall materials) that make up the building so that the building has the performance desired by the user U. The user U is, for example, a person in charge of a contractor in charge of building or renovating the building. The user U may also be, for example, the owner of the building or a prospective occupant of the building.

[0026] The performance analysis system S includes an information processing device 1 and an information terminal 2. The information processing device 1 is a computer for providing information indicating the performance of a building to a user U in response to operations of the user U using the information terminal 2. The information processing device 1 is, for example, a cloud server that can be accessed by the information terminal 2 used by the user U via a wireless communication line W and a network N, but the form of the information processing device 1 is arbitrary.

[0027] The information terminal 2 is a computer used by the user U, and may be, for example, a tablet or a smartphone, but the information terminal 2 may take any form. The information terminal 2 is configured to be able to communicate with the information processing device 1 via, for example, a wireless communication line W and a network N.

[0028] When the basic structure of a building, including its floor plan, is decided, the type of wall is a factor that greatly affects performance. Therefore, the information processing device 1 is configured to present, on the information terminal 2, information indicating the performance of the building for each wall type selected by the user U using the information terminal 2. By checking the performance of each wall type displayed on the information terminal 2, the user U can select a wall type so that the building meets the desired performance.

[0029] An overview of the performance analysis system S will be described below with reference to Fig. 1. When a user U operates an information terminal 2 to start application software for providing information indicating the performance of a building, the information terminal 2 starts an operation for accepting input of information required for the information processing device 1 to calculate the performance of the building.

[0030] First, the information terminal 2 displays a screen for inputting information about the structure of the building (hereinafter referred to as "building structure information"). The building structure information is information indicating the structure of the building that is necessary for the information processing device 1 to analyze the performance of the building, and includes structural data indicating the structure of the building, such as the structural type, the exterior appearance of the building, the layout, the materials of the main structures, the types of walls, the types of floorboards, the types of roofing materials, the positions of openings, etc.

[0031] The structural data may be, for example, text data indicating the structure of a building, or may be image data generated by the user U by photographing the building with a camera, or design data of the building. The structural data may be data indicating the three-dimensional shape of the building created by the user U using a tool such as a LiDAR scanner or a ToF (Time of Flight) sensor. The image data or design data includes, for example, data indicating the appearance of one or more wall surfaces of the building.

[0032] The structural type may be, for example, a rigid frame structure, a braced structure, or a wall structure. The wall type may be, for example, a nonstructural masonry wall with a reinforcement coating, a structural masonry wall with a reinforcement coating, a nonstructural masonry wall without a reinforcement coating, a structural masonry wall without a reinforcement coating, a concrete structural wall, a precast concrete nonstructural wall, a wood panel, a wooden material, a lumber material, glass, a metal plate, etc. Note that a reinforcement coating is a coating that improves the strength or bearing capacity of the coated object (e.g., a wall), and a reinforcement coating layer is a layer formed on the object (e.g., a wall) for the reinforcement coating.

[0033] The types of reinforcing-coated walls may include multiple types that differ in at least one of the type of paint that forms the reinforcing coating layer, the application area, and the application thickness.The types of walls may include multiple types that differ in the combination of the type of paint that forms the reinforcing coating layer, the application area, and the application thickness.

[0034] The type of paint may be represented, for example, by the percentage of fiber contained in the paint. In this case, the type of paint may be, for example, a 4% product, an 8% product, etc. Furthermore, when a specific paint is diluted before use, the type of paint may be represented by the details of the dilution (the type of thinner used for dilution, the dilution ratio (the ratio of the amount of the specific paint before dilution to the amount of thinner), etc.). When a specific paint product is known as a paint capable of forming a reinforcing coating layer, the type of paint may be represented by the product name. Furthermore, when the performance of a paint is represented by a standard according to the reinforcing coating layer that the paint can form, the type of paint may be represented by the standard to which the paint to be used corresponds.

[0035] The coating range may be expressed, for example, by the area to which paint is applied relative to the surface area of ​​the wall, or by the shape and position of the region on the wall to which paint is applied. The coating thickness may be expressed, for example, as a multiple of the minimum controllable thickness (e.g., 0.25 mm). The coating thickness may also be expressed by the number of times the paint is applied. When the user U inputs the building structure information into the information terminal 2, the information terminal 2 transmits the building structure information to the information processing device 1.

[0036] The information terminal 2 transmits building location information indicating the current location determined based on radio waves received from, for example, a GPS (Global Positioning System) satellite to the information processing device 1. The information terminal 2 may accept input of building location information indicating the area or location where a building is built, and transmit the input building location information to the information processing device 1. The building location information may be the latitude and longitude of the building, or the name of the area where the building is built. The information terminal 2 may display candidate area names for the building, and create building location information indicating the area name selected by the user U.

[0037] The information processing device 1 analyzes various performance characteristics of a building based on the building structure information. The performance characteristics include, for example, earthquake resistance, carbon dioxide emissions, fire resistance, sound insulation, energy efficiency, or cost. The information processing device 1 analyzes the performance characteristics of multiple buildings, each with different wall types, and notifies the information terminal 2 of performance information indicating the performance of the buildings, associating the multiple buildings with each other. The user U can determine the structure of the building, such as the wall type, by referring to the performance information displayed on the information terminal 2.

[0038] 2 is a diagram showing the configuration of the information processing device 1. The information processing device 1 has a communication unit 11, a storage unit 12, and a control unit 13. The control unit 13 has a reception unit 131, a performance identification unit 132, and an output unit 133.

[0039] The communication unit 11 is a communication interface for the information processing device 1 to transmit and receive data to and from the information terminal 2. The communication unit 11 inputs the building structure information and building position information received from the information terminal 2 to the reception unit 131. The communication unit 11 transmits the performance information input from the output unit 133 to the information terminal 2.

[0040] The storage unit 12 has storage media such as a read-only memory (ROM), a random access memory (RAM), and a solid-state drive (SSD). The storage unit 12 stores programs executed by the control unit 13. The storage unit 12 also stores various data used by the control unit 13 to analyze the performance of the building. For example, the storage unit 12 stores wall performance data indicating the individual performance corresponding to each type of wall.

[0041] Figure 3 is a diagram showing an example of wall performance data. The wall performance data shown in Figure 3 associates wall type with the seismic performance of the wall alone, the carbon dioxide emissions of the wall alone, the sound insulation performance of the wall alone, the fire resistance performance of the wall alone, and the cost of the wall alone. The numbers shown in Figure 3 correspond to the rank of the wall's individual performance, with rank 3 indicating the best performance. Specifically, rank 3 indicates the highest seismic performance, the lowest carbon dioxide emissions, the highest sound insulation performance, the highest fire resistance performance, and the lowest cost.

[0042] While Figure 3 shows the rank of individual performance, the wall performance data may also include values ​​for each performance. The value indicating seismic performance is, for example, the wall coefficient or wall standard strength (kN / m). Carbon dioxide emissions are the total amount of carbon dioxide emitted by one or more components constituting a wall per unit area (e.g., 1 square meter). Sound insulation performance is, for example, a value (dB) measured using a measurement method specified in Japanese Industrial Standards JIS A1416. Fire resistance performance is a value measured using a specified fire resistance test method. Cost is the total cost of the components constituting the wall and the manufacturing cost of the wall. Wall type may be indicated by a combination of the wall structure and the wall area. In this case, carbon dioxide emissions are the total amount of carbon dioxide emitted by one or more components constituting each wall.

[0043] The storage unit 12 may store wall information indicating the wall type and the material contained in the wall, and emission information indicating the relationship between the material and the carbon dioxide emission amount. In this case, the performance identification unit 132 can calculate the carbon dioxide emission amount of the wall for each wall type based on the wall information and the emission information.

[0044] The control unit 13 includes, for example, a CPU (Central Processing Unit). The control unit 13 executes the programs stored in the storage unit 12, thereby functioning as a reception unit 131, a performance specification unit 132, and an output unit 133.

[0045] The reception unit 131 receives various types of information via the communication unit 11. For example, the reception unit 131 receives building structure information set by the user U on the information terminal 2. As an example, the reception unit 131 receives a selection of a wall type to be used from a plurality of candidate wall types, which are types of walls that can be installed in a building. As shown in FIG. 3 , the plurality of candidates include a painted wall having a reinforcing coating layer and an unpainted wall having no reinforcing coating layer. The reception unit 131 may display a plurality of wall types such as those shown in FIG. 3 on the information terminal 2 and allow the user U to select a wall type. The reception unit 131 receives information indicating the wall type selected by the user U from the information terminal 2.

[0046] The reception unit 131 may receive a selection of a wall type associated with each of a plurality of walls provided in the building. The reception unit 131 may receive a selection of a wall type associated with the position of the wall. To achieve this, the reception unit 131 may display at least one of an exterior view or a floor plan of the building on the information terminal 2 based on information indicating the exterior view and floor plan of the building included in the building structure information, and receive a selection of a wall type corresponding to a portion selected by the user U from a plurality of portions on the exterior view or floor plan.

[0047] 4A and 4B are diagrams showing examples of an exterior view and a floor plan of a building displayed on the information terminal 2. FIG. 4A is an exterior view of a building viewed from a first direction, FIG. 4B is an exterior view of a building viewed from a second direction, and FIG. 4C is a floor plan. When a user U selects a part in the exterior view or floor plan, the reception unit 131 displays multiple wall type candidates on the information terminal 2. When the user U selects a wall type candidate that the user U wants to use from the multiple wall type candidates, the reception unit 131 stores the wall type selected by the user U in the storage unit 12 in association with the part selected by the user U. The reception unit 131 receives the selection of wall types from the user U for all walls included in the exterior view or floor plan.

[0048] The receiving unit 131 may display, on the information terminal 2, schematic diagrams of walls corresponding to a plurality of application patterns that differ in the type, application area, and application thickness of paint to be applied to the wall, and may receive a selection of one or more wall types with different paint application patterns from the user U. The receiving unit 131 may receive a selection of an application pattern for each of a plurality of walls included in the building.

[0049] 5A and 5B are examples of schematic diagrams of multiple walls with different coating patterns. In the coating pattern shown in FIG. 5A, the entire wall is coated with one type of paint at a uniform thickness. In the coating pattern shown in FIG. 5B, the coating thickness differs in each of the regions R1, R2, and R3. Furthermore, the type of paint used in regions R1 and R2 is different from the type used in region R3. The schematic diagram shown in FIG. 5 may further include information indicating the cost of the paint used. Displaying such a schematic diagram on the information terminal 2 makes it easier for the user U to select the type of wall whose performance he or she wishes to compare.

[0050] The reception unit 131 may receive a selection of wall types for each of a plurality of buildings whose performance is to be considered by the user U. To achieve this, the reception unit 131 may cause the information terminal 2 to display at least one of exterior drawings or floor plans of three or more buildings that differ from each other in at least one of appearance, structure, and floor plan, and receive a selection of wall types corresponding to the plurality of buildings selected by the user U from the three or more buildings.

[0051] The performance identifying unit 132 identifies the performance of the building based on the wall types selected by the receiving unit 131. The performance identifying unit 132 may identify the performance of the building based on a combination of the types of multiple walls. When the receiving unit 131 receives the selection of multiple buildings, the performance identifying unit 132 may identify the performance of each of the multiple buildings.

[0052] Specifically, the performance identification unit 132 analyzes the earthquake resistance performance of the building based on the building structural information and building location information for each of the multiple wall types selected by the user U. The information processing device 1 simulates the direction and magnitude of forces acting on the building for each intensity of an earthquake that occurs in the area where the building is built, using an analysis method such as a continuum analysis method like the finite element method (FEM) or a discontinuum analysis method like the discrete element method (DEM) or the applied element method (AEM).

[0053] The performance identification unit 132 may analyze the seismic performance of the building assuming that all walls are of the same type, or may analyze the seismic performance of the building based on the type selected for each wall by the user U. The performance identification unit 132 may also analyze the seismic performance of the building based further on the shape and area of ​​each wall indicated by the building structural information. The information processing device 1 calculates an index indicating the seismic performance of the building using, for example, data indicating the strength of each wall calculated in advance for each wall shape, area, and type.

[0054] By using walls coated with fiber-reinforced paint in a building, a seismic damping effect that suppresses vibration of the building is produced, improving the earthquake resistance of the building. The earthquake resistance of a building can also be improved by applying paint at different thicknesses in different areas of the building, causing the areas to vibrate at different phases. The information processing device 1 analyzes the earthquake resistance of each wall type by simulating the behavior of multiple buildings with different wall types when an earthquake occurs in the area where the buildings are built.

[0055] As an example, the performance identification unit 132 uses a numerical analysis method such as the finite element method, the distinct element method, or the applied element method to analyze the impact on the building for each intensity of earthquakes expected to occur in the area where the building is built. The performance identification unit 132 selects whether to use a continuum analysis method or a discontinuum analysis method based on, for example, the expected intensity of the earthquake and the magnitude of damage estimated to occur to the building due to an earthquake of that intensity, and analyzes the impact on the building using the selected analysis method. The performance identification unit 132 identifies the state of the ground in the area where the building is built by referring to the ground information storage unit 121, and analyzes the impact on the building taking into account the identified state of the ground.

[0056] For example, the performance specifying unit 132 analyzes the seismic resistance of a building using a continuum analysis method when it is expected that the structure will suffer little damage from an earthquake, and analyzes the seismic resistance of a building using a discontinuum analysis method when it is expected that the structure will suffer significant damage from a specified earthquake. Specifically, when an earthquake with a seismic intensity of less than 3 occurs, the performance specifying unit 132 assumes that the building will suffer relatively little damage and analyzes the building as a continuum using the finite element method. On the other hand, when an earthquake with a seismic intensity of 6 or higher occurs, the performance specifying unit 132 assumes that the building will suffer relatively significant damage, resulting in cracks or destruction, and analyzes the building as a discontinuum using the distinct element method. When an earthquake with a seismic intensity of 3 or higher but less than 6 occurs, the performance specifying unit 132 performs analysis using, for example, both the finite element method and the distinct element method.

[0057] In other words, when the earthquake to be analyzed is low in intensity, it is desirable to perform an analysis that focuses on avoiding cracks and damage to structural members, and therefore the finite element method, which is suitable for such analytical calculations, is preferred.On the other hand, when the earthquake to be analyzed is high in intensity, it is desirable to perform an analysis that focuses on damage to structural members or the collapse of building walls, and therefore the distinct element method, which is suitable for such analytical calculations, is preferred.

[0058] The performance specifying unit 132 may also be capable of applying at least two or more analysis methods (including, but not limited to, the discrete element method and the finite element method). In this case, the performance specifying unit 132 may apply an analysis method suitable for each analysis, from the perspective of accuracy of the calculation results, calculation speed, or both, when performing an analysis focusing on avoiding crack occurrence and damage to structural members, and when performing an analysis focusing on damage to structural members or the collapse of walls or buildings. In this way, by the performance specifying unit 132 changing the analysis method depending on the intensity of the earthquake to be analyzed, it is possible to improve the accuracy of the analysis results, calculation speed, or both within each earthquake intensity range. The performance specifying unit 132 may further improve the accuracy of the analysis results by combining the discrete element method and the finite element method.

[0059] However, if the information terminal 2 presents to the user U as a candidate wall type that is unlikely to satisfy the seismic performance that the user U considers necessary, the user U may end up performing a needless selection task. Therefore, the performance identification unit 132 may identify the seismic performance of each of the multiple candidates before the reception unit 131 receives the selection of the wall type. In this case, the reception unit 131 receives the selection of the wall type from one or more candidates whose seismic performance identified by the performance identification unit 132 is equal to or higher than the standard level, thereby preventing the user U from performing a needless selection task.

[0060] The performance specifying unit 132 may specify the amount of carbon dioxide emitted by the building as performance based on the wall type selected by the receiving unit 131, the number of walls of one or more wall types used in the building, and the area of ​​each wall. By referring to the wall performance data, the performance specifying unit 132 calculates the carbon dioxide emissions of the entire building by adding the results of multiplying the carbon dioxide emissions per unit area of ​​each of the multiple wall types used in the building by the number of walls of the wall type corresponding to the carbon dioxide emissions and the area of ​​each wall.

[0061] As described above, the performance identifying unit 132 may calculate the carbon dioxide emissions of a wall based on the wall information and the emission amount information. Specifically, the performance identifying unit 132 first refers to the wall information stored in the storage unit 12 to identify the amount of each of the multiple materials used in the building based on the materials included in the wall type selected by the receiving unit 131 and the number of walls of each of the multiple wall types used in the building. Next, the performance identifying unit 132 identifies the amount of carbon dioxide emitted by the multiple materials as the performance of the building based on the emission amount information.

[0062] The performance specification unit 132 may specify the fire resistance of the building based on the wall type selected by the specification unit 131, the number of walls of each of the one or more wall types used in the building, and the fire resistance of individual walls corresponding to the wall types. The greater the number of walls of a type with a higher individual fire resistance, the higher the fire resistance of the building.

[0063] The performance specifying unit 132 may specify the soundproofing performance of the multiple spaces within the building and the space outside the building based on the wall types of each of the multiple walls within the building selected by the receiving unit 131 and the soundproofing performance of individual walls corresponding to the wall types of one or more walls adjacent to at least one of the multiple spaces within the building and the space outside the building. For example, when a sound of a predetermined magnitude is generated at a first position specified by a user U within the building or outside the building, the performance specifying unit 132 calculates the magnitude of the sound heard at a second position specified by the user U within the building or outside the building across one or more walls of the building, thereby specifying the soundproofing performance in association with a combination of the first position and the second position. The performance specifying unit 132 may specify the soundproofing performance of a building or a specific room or group of rooms within a building (e.g., a unit within a building in an apartment building), and may specify how these are evaluated by comparing them with a pre-stored standard for soundproofing performance.

[0064] The performance specifying unit 132 may specify the carbon dioxide reduction amount based on the difference between the amount of carbon dioxide emitted by a building when a reference wall is used and the amount of carbon dioxide emitted by a building using walls of the wall type selected by the receiving unit 131. The performance specifying unit 132 may specify the cost taking carbon credits into consideration by subtracting an amount corresponding to the carbon credits corresponding to the specified carbon dioxide reduction amount from the cost of the building specified based on the cost of the walls of the wall type selected by the receiving unit 131.

[0065] Specifically, the performance specifying unit 132 specifies the cost of a building by adding up the unit cost of each of the multiple walls used in the building, the cost of paint used to paint the building, etc. When the carbon dioxide emissions of the building are reduced compared to a building constructed using a reference wall, the performance specifying unit 132 may specify the cost taking carbon credits into account by referring to data that associates the amount of carbon dioxide reduction with the amount of carbon credits, and subtracting the amount of carbon credits corresponding to the amount of carbon dioxide reduction from the specified cost.

[0066] The output unit 133 outputs performance information indicating the performance of the building identified by the performance identifying unit 132. The output unit 133 transmits the performance information indicating the multiple performances to the information terminal 2, for example, in association with the exterior appearance or layout of the building.

[0067] When the performance identification unit 132 identifies the cost of a building taking carbon credits into consideration, the output unit 133 may output the cost of the building as performance information, as well as the cost reduction amount due to carbon credits. As an example, if a wall constructed of blocks filled with cement and containing rebar is used as a reference wall, the carbon dioxide emissions of the building can be reduced by reducing the amount of cement and rebar used and using a wall coated with paint that forms a reinforcing coating layer. In such a case, the output unit 133 outputs the cost reduction amount due to carbon credits along with information indicating the difference from the reference wall. By outputting such information, the output unit 133 makes it easier for the user U to understand the effect of changing the type of wall.

[0068] FIG. 6 is a diagram illustrating an example of performance information output by the output unit 133. The performance information illustrated in FIG. 6 shows cost, earthquake resistance, carbon dioxide emissions, fire resistance, sound insulation, energy efficiency, and environmental impact in association with multiple buildings (Building A, Building B) that use different types of walls. The output unit 133 may output a radar chart including evaluation values ​​of multiple performances, as shown in the "Overall Comparison" section of FIG. 6. By outputting such performance information by the output unit 133, the user U can determine the wall type while comparing performances that are most important to him or her.

[0069] [Processing Flow in Information Processing Device 1] Fig. 7 is a diagram showing the processing flow in the information processing device 1. The flowchart shown in Fig. 7 starts when the user U starts application software for selecting a wall type on the information terminal 2.

[0070] First, the receiving unit 131 acquires data indicating the conditions of the building to be compared in performance from the information terminal 2 (S1). The conditions of the building include, for example, the construction site of the building, the type of structure of the building, and the layout.

[0071] Next, the performance identification unit 132 determines whether structural model data that matches the building conditions acquired in S1 is stored in the storage unit 12 (S2). If structural model data is stored (YES in S2), the reception unit 131 acquires the structural model data from the storage unit 12 (S3). If structural model data is not stored (NO in S2), the reception unit 131 displays a screen for inputting a structural model on the information terminal 2 and receives input of a structural model from the user U (S4).

[0072] Next, the receiving unit 131 receives a selection of ground characteristics at the location of the building from the information terminal 2 (S5). Ground characteristics are characteristics that affect the susceptibility to shaking when an earthquake occurs, such as the hardness of the ground and the use of the land before development (for example, whether it was a rice paddy or a forest). The receiving unit 131 may display candidate ground characteristics on the information terminal 2 and receive the candidate ground characteristics selected by the user U.

[0073] Next, the reception unit 131 receives a selection of a wall type from the information terminal 2 (S6). The reception unit 131 may receive a selection of each of a plurality of wall types. The reception unit 131 may display candidate wall types on the information terminal 2 and receive the candidate wall type selected by the user U.

[0074] The receiving unit 131 also receives a selection of the type of component other than the wall from the information terminal 2 (S7). The component other than the wall may be, for example, a ceiling material, a floor material, a roof material, or a component of an opening. The receiving unit 131 may display candidate types for each of these components on the information terminal 2 and receive the candidate type selected by the user U.

[0075] The performance identifying unit 132 identifies the performance of the building by analyzing the performance of the building based on the combination of the selected wall types (S8). The output unit 133 outputs information indicating the performance identified by the performance identifying unit 132 (S9).

[0076] [First Modification] In the above description, the information processing device 1 analyzes the performance of a building according to the type of wall selected by the user U on the information terminal 2. However, the information terminal 2 may have the functions of the information processing device 1, and the processor of the information terminal 2 may execute a program to analyze the performance of a building according to the type of wall selected by the user U and display the performance information on the display. By operating the information terminal 2 in this manner, it becomes possible for the user U to select a type of wall using the information terminal 2 even when the state of the network N is poor.

[0077] [Second Modification] The control unit 13 of the information processing device 1 may further include a structural design unit that changes the structural model data of the building based on the performance identified by the performance identification unit 132. For example, if the performance identified by the performance identification unit 132 does not satisfy a condition previously set by the user U, the structural design unit may change the structural model data of the building so that the performance satisfies the condition. To improve the performance that does not satisfy the condition, the structural design unit changes the configuration of the parts that affect the performance in the structural model data in which performance was previously identified, and then the control unit 13 executes the processes from S5 to S9 of the flowchart shown in FIG. 7 after updating the structural model data. The control unit 13 repeats this process until the performance identified by the performance identification unit 132 satisfies the condition, thereby generating structural model data that satisfies the condition.

[0078] The output unit 133 may output the plurality of structural model data thus generated in association with the performance, thereby enabling the user U to select structural model data that satisfies the performance that the user U considers necessary and that the user U considers to be the best.

[0079] [Third Modification] In the above description, earthquake resistance, carbon dioxide emissions, fire resistance, sound insulation, energy efficiency, and cost have been exemplified as building performance, but wind resistance or thermal insulation (heat transmission coefficient) may also be included as building performance. The performance identification unit 132 may identify the wind resistance of a building based on the wind resistance of a single wall corresponding to the wall type of one or more walls that are in contact with the space outside the building. For example, the performance identification unit 132 identifies the wind resistance of the wall with the lowest wind resistance among multiple walls as the wind resistance of the building.

[0080] The performance specifying unit 132 may also specify the thermal insulation performance of the building based on the overall heat transmission coefficient of a single wall corresponding to the wall type of one or more walls that are in contact with the outside space of the building. For example, the performance specifying unit 132 may specify the average value of the thermal insulation performance of the multiple walls as the thermal insulation performance of the building. The performance specifying unit 132 may also specify the minimum thermal insulation performance of the multiple walls as the thermal insulation performance of the building.

[0081] [Fourth Modification] In the above description, the wall types have been assumed to be "non-structural walls with a reinforcing coating layer," "structural walls with a reinforcing coating layer," "non-structural walls without a reinforcing coating layer," and "structural walls without a reinforcing coating layer," as shown in FIG. 3 . However, the wall type may not indicate whether it is a non-structural wall or a structural wall, and the wall type may be represented as "walls with a reinforcing coating layer" and "walls without a reinforcing coating layer." In this case, the performance specifying unit 132 may specify the performance of the building by treating "walls without a reinforcing coating layer" as non-structural walls and "walls with a reinforcing coating layer" as structural walls. The performance specifying unit 132 may specify the performance of the building by taking into account beams and columns, without considering components other than the beams and columns.

[0082] To make it easier for the user U to select whether or not to apply paint to form a reinforcing coating layer, the receiving unit 131 may receive a setting for whether or not to apply paint to form a reinforcing coating layer to each wall or to all walls. In this case, the performance specifying unit 132 may specify the performance of the building by treating walls set to not be painted with paint to form a reinforcing coating layer as non-structural walls and walls set to be painted with paint to form a reinforcing coating layer as structural walls. This allows the user U to easily compare the performance of the building when painted to form a reinforcing coating layer and the performance of the building when not painted to form a reinforcing coating layer.

[0083] Furthermore, the receiving unit 131 may receive a setting for whether a wall is automatically treated as a structural wall when paint that forms a reinforcing coating layer is applied. When the receiving unit 131 receives a setting for not automatically treating a wall as a structural wall when paint that forms a reinforcing coating layer is applied, the receiving unit 131 may receive a setting for whether the wall is a structural wall or a non-structural wall. By receiving such a setting, a wall that will not become a structural wall even when paint that forms a reinforcing coating layer is applied is not automatically treated as a structural wall, and the user U can set it as a non-structural wall, thereby improving the accuracy of performance identification by the performance identifying unit 132.

[0084] The receiving unit 131 may accept a setting that does not take into account the presence or absence of a reinforcing coating layer when determining whether a wall is a structural wall or a non-structural wall. In this case, a wall that is a non-structural wall when it does not have a reinforcing coating layer is considered to be a non-structural wall even if it has a reinforcing coating layer, and a wall that is a structural wall when it does not have a reinforcing coating layer is considered to be a structural wall even if it has a reinforcing coating layer.

[0085] Depending on the structure of a wall, the thickness of the reinforcing coating layer may determine whether the wall is a non-structural wall or a structural wall. Therefore, the receiving unit 131 may receive a setting for the thickness of the reinforcing coating layer (i.e., the applied thickness of the paint), and the performance specifying unit 132 may determine whether to treat the wall as a non-structural wall or a structural wall based on the thickness of the reinforcing coating layer received by the receiving unit 131.

[0086] If it is determined that the wall should be treated as a non-structural wall, the performance specifying unit 132 may specify what thickness of the reinforcing coating layer will make it a structural wall, for example, based on the structure and material of the wall set via the receiving unit 131. The performance specifying unit 132 outputs the specified thickness via the output unit 133, thereby enabling the user U to grasp the coating thickness of the paint required to make the wall a structural wall. The performance specifying unit 132 may specify a combination of the type, application range, and application thickness of the paint required to form a reinforcing coating layer that can turn the non-structural wall into a structural wall, and output one or more of the specified combinations via the output unit 133.

[0087] [Effects of Information Processing Device 1] As described above, the information processing device 1 includes a reception unit 131 that receives a selection of a wall type to be used from a plurality of candidate wall types that are types of walls that can be installed in a building, a performance identification unit 132 that identifies the performance of the building based on the wall type selected by the reception unit 131, and an output unit 133 that outputs performance information indicating the performance of the building identified by the performance identification unit 132. With the information processing device 1 configured in this manner, the user U can determine the wall type after understanding the difference in building performance depending on the wall type used in the building. As a result, for example, it is possible to easily compare whether it is better to apply a reinforcing coating to a low-cost wall or to use a high-cost wall.

[0088] Furthermore, the receiving unit 131 can receive a selection of a wall type for each of multiple walls in the building. Then, the performance specifying unit 132 can analyze the performance of the building for each combination of wall types. As a result, the user U can select the optimal type for each of the multiple walls in the building while taking into consideration the balance between cost and performance.

[0089] <Second embodiment> In the first embodiment, the information processing device 1 outputs performance information corresponding to the type of wall selected by the user U. However, the second embodiment differs from the first embodiment in that the information processing device 1 outputs information regarding the type of wall that allows the building to satisfy the performance desired by the user U.

[0090] The information processing device 1 according to the second embodiment is configured as follows: The reception unit 131 receives, from the information terminal 2, specification of performance conditions required for a building. The performance conditions are, for example, tolerance levels set for each of the building performance elements, such as cost, earthquake resistance, carbon dioxide emissions, fire resistance, and sound insulation. The tolerance levels may be expressed by values ​​or may be expressed qualitatively.

[0091] The performance specification unit 132 specifies the performance of the building for each combination of wall types that can be used for multiple walls that can be used in the building. The wall types that can be used for each of the multiple walls may be stored in advance in the storage unit 12, or may be set by the user U via the reception unit 131. The performance specification unit 132 specifies the performance of the building for each combination of wall types for the multiple walls using the same procedure as in the first embodiment.

[0092] The output unit 133 outputs information indicating wall types for which the building performance identified by the performance identification unit 132 satisfies the performance conditions accepted by the acceptance unit 131. The output unit 133 outputs, for example, a combination of wall types that corresponds to the highest performance among combinations of wall types that satisfy all of the conditions of the allowable levels specified by the user U. The output unit 133 may output information indicating multiple combinations of wall types in descending order of performance.

[0093] When the receiving unit 131 receives from the user U a designation of the priorities of multiple elements included in the performance conditions, the output unit 133 may output information indicating a combination of wall types in which the element with the highest priority is at or above an acceptable level. When the receiving unit 131 receives designation of one or more elements that the user U desires to be at or above an acceptable level, the output unit 133 may output information indicating a combination of wall types in which one or more elements designated by the user U are at or above an acceptable level.

[0094] In this way, the information processing device 1 outputs information indicating the wall type that satisfies the performance of the building desired by the user U, so that the user U does not need to select a candidate wall type, making it easier for the user U to construct a building with the performance desired even if the user U does not have knowledge about the effect that wall type has on performance.

[0095] <Other Embodiments> In other embodiments, the information processing device 1 may receive the basic structure of a building (such as the floor plan and / or the exterior) and output one or more performance conditions that the building can satisfy, or one or more wall types that are types of walls that can be installed in the building that satisfy the performance conditions. By configuring the information processing device 1 in this way, when only the basic structure of the building has been determined, the user U can recognize examples of typical performance conditions and / or wall types of the building.

[0096] More specifically, for example, the information processing device 1 outputs examples of multiple performance conditions that should be applied to the building and wall types that should be adopted for the building to achieve these performance conditions. The multiple performance conditions may include, for example, multiple perspectives that can be adopted for the building, such as performance conditions that place particular emphasis on cost, performance conditions that place particular emphasis on earthquake resistance, and performance conditions that place both cost and earthquake resistance at a moderate level. The information processing device 1 may output one or more wall types that will achieve these performance conditions simultaneously with or after outputting the performance conditions.

[0097] In order for the information processing device 1 to execute the above processing, the reception unit 131 receives information regarding the basic structure of the building via the communication unit 11. The performance identification unit 132 identifies the number and sizes of various components, such as multiple walls, to be provided in the building based on the basic structure of the building. The performance identification unit 132 identifies the performance of the building for each combination of different types (e.g., wall types) of the multiple identified components.

[0098] The output unit 133 outputs, as a performance condition that can be satisfied by the building, a performance that satisfies a predetermined standard from among the multiple performances corresponding to the multiple combinations identified by the performance identifying unit 132. For example, the output unit 133 outputs, as a performance condition, a performance that is higher than a level set for the user U from among the multiple performances corresponding to the multiple combinations. The output unit 133 may output a combination of wall types that satisfies the performance condition in association with the performance condition.

[0099] Furthermore, in the above description, an example has been given in which the storage unit 12 stores data related to costs, but the data related to costs may also be stored in an external device. The information processing device 1 may periodically acquire data related to costs stored in an external device and store the acquired data in the storage unit 12. Furthermore, the information processing device 1 may receive data related to costs from a supplier of walls, paint, or the like, and calculate the cost of a building based on the received data.

[0100] The present invention has been described above using embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, all or part of the device can be configured by functionally or physically distributing or integrating in any unit. Furthermore, new embodiments resulting from any combination of multiple embodiments are also included in the embodiments of the present invention. The effects of the new embodiments resulting from the combination also have the effects of the original embodiments.
