[0022] First Embodiment [Overview of Performance Analysis System S] FIG. 1 is a diagram for explaining an overview of a 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 will change by changing the types of components (e.g., wall materials) that make up the building so that the building will have 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.

[0023] 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.

[0024] 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.

[0025] 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, to the information terminal 2, information indicating the performance of the building for each wall type selected by a 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 satisfies the desired performance.

[0026] An overview of the performance analysis system S will be described below with reference to Fig. 1. When a user U operates the 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.

[0027] 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.

[0028] The structural data is, for example, text data indicating the structure of a building, but may also 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 also 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.

[0029] 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 reinforced coated masonry nonstructural wall, a reinforced coated masonry structural wall, a reinforced uncoated masonry nonstructural wall, an uncoated masonry structural wall, a concrete structural wall, a precast concrete nonstructural wall, wood panels, wooden materials, lumber, glass, metal plates, etc.

[0030] The type of reinforced-coated wall may include a plurality of types that differ in at least one of the type of paint that forms the reinforced-coating layer, the coating area, and the coating thickness. The type of wall may include a plurality of types that differ in the combination of the type of paint that forms the reinforced-coating layer, the coating area, and the coating thickness.

[0031] 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 reinforced coating layer, the type of paint may be represented by the product name. Furthermore, when the performance of paint is standardized according to the reinforced coating layer that the paint can form, the type of paint may be represented by the standard of the paint to be used.

[0032] 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 is 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 building structure information into the information terminal 2, the information terminal 2 transmits the building structure information to the information processing device 1.

[0033] The information terminal 2 transmits building position information indicating the current position determined based on radio waves received from a GPS (Global Positioning System) satellite, for example, to the information processing device 1. The information terminal 2 may accept input of building position information indicating the area or location where a building is built, and transmit the input building position information to the information processing device 1. The building position 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 position information indicating the area name selected by the user U.

[0034] 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 a different type of wall, and notifies the information terminal 2 of performance information indicating the performance of the buildings, associating the performance information with the multiple buildings. The user U can determine the structure of the building, such as the type of wall, by referring to the performance information displayed on the information terminal 2.

[0035] [Configuration of information processing device 1] 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.

[0036] 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.

[0037] The storage unit 12 has storage media such as a ROM (Read Only Memory), a RAM (Random Access Memory), and an SSD (Solid State Drive). 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.

[0038] FIG. 3 is a diagram showing an example of wall performance data. The wall performance data shown in FIG. 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 FIG. 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.

[0039] While Figure 3 shows the rank of individual performance, the wall performance data may also include values ​​for each performance. Values ​​indicating seismic performance are, for example, wall coefficient or wall standard strength (kN / m). Carbon dioxide emissions are the total amount of carbon dioxide emitted by one or more components that make up a wall per unit area (e.g., 1 square meter). Sound insulation performance is a value (dB) measured using a measurement method specified in Japanese Industrial Standard JIS A1416, for example. Fire resistance performance is a value measured using a specified fire resistance test method. Cost is the total cost of the components that make up the wall and the cost of manufacturing the wall. Note that 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 that make up each wall.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] FIG. 4 is a diagram showing examples of an exterior view and a floor plan of a building displayed on the information terminal 2. FIG. 4(a) is an exterior view of a building viewed from a first direction, FIG. 4(b) is an exterior view of a building viewed from a second direction, and FIG. 4(c) is a floor plan. When the 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.

[0045] 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 the paint to be applied to the wall, and may receive a selection of one or more wall types that differ in the application area of ​​the paint 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.

[0046] FIG. 5 shows examples of schematic diagrams of multiple walls with different coating patterns. In the coating pattern shown in FIG. 5(a), the entire wall is coated with one type of paint in a uniform thickness. In the coating pattern shown in FIG. 5(b), 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.

[0047] The reception unit 131 may receive a selection of wall types for each of multiple buildings whose performance the user U is considering. 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 multiple buildings selected by the user U from the three or more buildings.

[0048] The performance identification unit 132 identifies the performance of the building based on the wall types selected by the reception unit 131. The performance identification unit 132 may identify the performance of the building based on a combination of the types of multiple walls. When the reception unit 131 receives the selection of multiple buildings, the performance identification unit 132 may identify the performance of each of the multiple buildings.

[0049] Specifically, the performance identification unit 132 analyzes the earthquake resistance performance of the building based on the building structural information and building position information for each of the multiple wall types selected by the user U. The information processing device 1 simulates the direction and magnitude of the force 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).

[0050] 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.

[0051] By using walls coated with fiber-reinforced paint in a building, a seismic damping effect that suppresses the vibration of the building is generated, improving the earthquake resistance of the building. The earthquake resistance of a building can also be improved by applying paint at different thicknesses to 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.

[0052] 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 condition 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 condition of the ground.

[0053] For example, the performance specifying unit 132 analyzes the earthquake 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 earthquake 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.

[0054] 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.

[0055] The performance specifying unit 132 may also be configured to apply at least two or more analysis methods (including, but not limited to, the discrete element method and the finite element method) so that it can apply an analysis method appropriate 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 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.

[0056] 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.

[0057] The performance identification unit 132 may identify the amount of carbon dioxide emitted by the building as performance based on the wall type selected by the reception 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 identification 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.

[0058] 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.

[0059] The performance identification unit 132 may identify the fire resistance of the building based on the wall type selected by the reception 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 type. The greater the number of walls of a type with a higher individual fire resistance, the higher the fire resistance of the building.

[0060] The performance identification unit 132 may identify the soundproofing performance of multiple spaces within the building and the space outside the building based on the wall types of each of multiple walls within the building, the selection of which is accepted by the accepting 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 volume occurs at a first position designated by a user U within the building or outside the building, the performance identification unit 132 calculates the volume of the sound heard at a second position designated by the user U within the building or outside the building, separated by one or more walls of the building, thereby identifying the soundproofing performance in association with a combination of the first position and the second position. The performance identification unit 132 may also identify 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 identify how these are evaluated by comparing them with a pre-stored standard for soundproofing performance.

[0061] The performance specifying unit 132 may specify the amount of carbon dioxide reduction 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 amount of carbon dioxide reduction from the cost of the building specified based on the cost of the walls of the wall type selected by the receiving unit 131.

[0062] 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 the 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.

[0063] 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.

[0064] 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 reinforced 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.

[0065] FIG. 6 is a diagram showing an example of performance information output by the output unit 133. The performance information shown 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 "Overall Comparison" in FIG. 6. By outputting such performance information by the output unit 133, the user U can determine the type of wall while comparing performances that are most important to him or her.

[0066] [Processing flow in information processing device 1] 7 is a diagram showing the flow of processing in the information processing device 1. The flowchart shown in FIG. 7 starts when the user U starts up application software on the information terminal 2 for selecting the type of wall.

[0067] First, the reception 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.

[0068] 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 the structural model from the user U (S4).

[0069] 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.

[0070] 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 cause the information terminal 2 to display candidate wall types, and receive the candidate wall type selected by the user U.

[0071] Furthermore, the reception unit 131 receives a selection of the type of component other than the wall from the information terminal 2 (S7). The component other than the wall is, for example, a ceiling material, a floor material, a roof material, or a component of an opening. The reception 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.

[0072] The performance identification 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 identification unit 132 (S9).

[0073] [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.

[0074] [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.

[0075] 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.

[0076] [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 building performance may also include wind resistance or thermal insulation (coefficient of overall heat transmission). 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.

[0077] The performance specifying unit 132 may also specify the thermal insulation performance of a 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 space outside the building. For example, the performance specifying unit 132 may specify the average value of the thermal insulation performance of 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.

[0078] [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 way, the user U can determine the wall type after understanding the difference in performance of the building depending on the wall type used in the building. As a result, for example, it is easy to compare whether it is better to apply a reinforcing coating to a low-cost wall or to use a high-cost wall.

[0079] Furthermore, the receiving unit 131 can receive a selection of the 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.

[0080] 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, but the second embodiment differs from the first embodiment in that the information processing device 1 outputs information regarding the type of wall that will enable the building to meet the performance desired by the user U.

[0081] The information processing device 1 according to the second embodiment is configured as follows: The reception unit 131 receives designation of performance conditions required for a building from the information terminal 2. 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.

[0082] The performance identification unit 132 identifies 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 identification unit 132 identifies the performance of the building for each combination of wall types for the multiple walls using the same procedure as in the first embodiment.

[0083] 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 corresponding 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.

[0084] 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.

[0085] 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 the wall type has on performance.

[0086] <Other embodiments> In another embodiment, the information processing device 1 may receive the basic structure of a building (floor plan and / or exterior, etc.) 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.

[0087] 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, and may be performance conditions that place particular emphasis on cost, performance conditions that place particular emphasis on earthquake resistance, performance conditions that place moderate importance on both cost and earthquake resistance, etc. 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.

[0088] In order for the information processing device 1 to execute the above processing, the receiving unit 131 receives information regarding the basic structure of the building via the communication unit 11. The performance specifying unit 132 specifies the number and size of various components, such as multiple walls, to be provided in the building based on the basic structure of the building. The performance specifying unit 132 specifies the performance of the building for each combination of different types (e.g., wall types) of the multiple specified components.

[0089] The output unit 133 outputs, as a performance condition that the building can satisfy, a performance that satisfies a predetermined standard from among the multiple performances corresponding to the multiple combinations identified by the performance identification 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.

[0090] Furthermore, in the above description, an example has been given in which the data on costs is stored in the storage unit 12, but the data on costs may also be stored in an external device. The information processing device 1 may periodically acquire data on costs stored in the external device and store the acquired data in the storage unit 12. Furthermore, the information processing device 1 may receive data on costs from a supplier of walls, paint, or the like, and calculate the cost of the building based on the received data.

[0091] 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 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. [Explanation of symbols]
