Summary of the Invention

Problems to be Solved by the Invention

[0005] Individuals and other clients who are building a wooden house communicate their wishes to the construction company before the design process begins. They refer to the plans presented by the construction company and convey their preferences regarding the exterior design, floor plan, and interior of the house. The construction company designs the wooden house while deciding whether to accept the client's requests based on past cases and experience. As a system to support such design, for example, the wooden house design support system described in Patent Document 1 searches for the general exterior design and interior layout of the house desired by the user based on the desired conditions or from options presented by the server.

[0006] However, construction companies often verify the structural safety of wooden houses after the overall design has been completed, using structural calculations or, more simply, wall quantity calculations. Therefore, even if the exterior of the house is decided at the beginning, the structural safety cannot be confirmed, which may lead to delays in verifying and ensuring safety, or even the need to modify the exterior design.

[0007] This invention has been made in view of the above circumstances, and its purpose is to provide a wooden house design support system, a wooden house design support device, and a wooden house design support method that enable the structural safety required for wooden houses to be ensured by selecting the exterior appearance of the house. [Means for solving the problem]

[0008] A wooden house design support system that solves the above problems is a wooden house design support system that supports the design of a wooden house, comprising: a house exterior setting unit that sets a selected house exterior which is one of a plurality of house exteriors that can be selected as a wooden house; a house floor plan setting unit that sets a set house floor plan based on one of a candidate house floor plans consisting of one or more house floor plans corresponding to the selected house exterior, and the set house floor plan which was made modifiable after selection; and a daylighting plan setting unit that sets a set daylighting plan based on one of a candidate daylighting plans consisting of one or more daylighting plans corresponding to the set house floor plan, and the set daylighting plan which was made modifiable after selection, wherein the selected house exterior includes design information as information necessary for structural calculations used to determine structural safety, and the house floor plan setting unit sets the set house floor plan on the condition that a result indicating structural safety can be obtained from the result of structural calculations based on the design information of the selected house exterior.

[0009] A wooden house design support device that solves the above problems is a wooden house design support device that supports the design of a wooden house, comprising: a house exterior setting unit in which a selected house exterior is set, which is a house exterior selected from among a plurality of house exteriors that can be selected as a wooden house; a house floor plan setting unit in which a set house floor plan is set, which is based on a house floor plan selected from a house floor plan candidate consisting of one or more house floor plans corresponding to the selected house exterior, and the set house floor plan was made modifiable after selection; and a daylighting plan setting unit in which a set daylighting plan is set, which is based on a daylighting plan selected from a daylighting plan candidate consisting of one or more daylighting plans corresponding to the set house floor plan, and the set daylighting plan was made modifiable after selection, wherein the selected house exterior includes design information as information necessary for structural calculations used to determine structural safety, and the house floor plan setting unit sets the set house floor plan on the condition that a result indicating structural safety can be obtained from the result of structural calculations based on the design information of the selected house exterior.

[0010] A wooden house design support method that solves the above problems is a wooden house design support method that supports the design of a wooden house, comprising: a house exterior setting step in which a selected house exterior is set, which is a house exterior selected from among a plurality of house exteriors that can be selected as a wooden house; a house floor plan setting step in which a set house floor plan is set, which is based on a house floor plan selected from a house floor plan candidate consisting of one or more house floor plans corresponding to the selected house exterior, and the set house floor plan was made modifiable after selection; and a daylighting plan setting step in which a set daylighting plan is set, which is based on a daylighting plan selected from a daylighting plan candidate consisting of one or more daylighting plans corresponding to the set house floor plan, and the set daylighting plan was made modifiable after selection, wherein the selected house exterior includes design information as information necessary for structural calculations used to determine structural safety, and in the house floor plan setting step, the set house floor plan is set on the condition that a result indicating structural safety is obtained from the result of structural calculations based on the design information of the selected house exterior.

[0011] With this configuration, structural calculations used to determine structural safety can be performed based on the design information included in the selected exterior of the wooden house, thereby obtaining the results of structural calculations for the wooden house. Furthermore, the setting of the floor plan of the selected house is set on the condition that the safety of the wooden house can be obtained from the results of the structural calculations. In other words, the setting of the floor plan of the selected house has very little impact on the safety of the wooden house. As a result, the structural safety required for a wooden house is ensured by selecting the exterior of the house.

[0012] In this way, the safety of a wooden house is ensured by the design of its exterior, which reduces the impact of the house layout and lighting plan on the building's safety, thus increasing the freedom of choice in house layouts and lighting plans. As a result, it becomes easier for construction companies to design layouts and lighting plans that provide high customer satisfaction.

[0013] A preferred configuration further includes a housing floor plan candidate selection unit that selects one or more housing floor plans as housing floor plan candidates from among a plurality of housing floor plans stored in advance, based on preset parameters, and a daylighting plan candidate selection unit that selects one or more daylighting plans as daylighting plan candidates from among a plurality of daylighting plans stored in advance, based on the selected housing floor plan.

[0014] With this configuration, a candidate house floor plan is selected from a number of pre-stored house floor plans based on pre-set parameters. This makes it possible to select a floor plan that has little impact on the exterior appearance or safety of the house as a candidate house floor plan. A candidate daylighting plan is selected from a number of pre-stored daylighting plans based on the selected house floor plan. This makes it possible to select a daylighting plan that has little impact on the exterior appearance or safety of the house as a candidate daylighting plan.

[0015] In a preferred configuration, the residential floor plan candidate selection unit selects the residential floor plan candidate based on the results of computer learning based on the relationship including the exterior of the selected residential building, the preset parameters, and the set residential floor plan, and the daylighting plan candidate selection unit selects the daylighting plan candidate based on the results of computer learning based on the relationship including the exterior of the selected residential building, the preset parameters, the set residential floor plan, and the set daylighting plan.

[0016] With this configuration, since the candidate house layouts are selected based on the results of computer learning, the candidate house layouts can be presented to the client in a more appropriate manner based on the selected house exterior, pre-set parameters, and the set house layout. Similarly, since the candidate daylighting plans are selected based on the results of computer learning, the candidate daylighting plans can be presented to the client in a more appropriate manner based on the relationship including the selected house exterior, pre-set parameters, the set house layout, and the set daylighting plan.

[0017] A preferred configuration further includes a housing floor plan learning unit that obtains the results of computer learning each time the relationship including the selected housing exterior, the preset parameters, and the set housing floor plan is set, and a daylighting plan learning unit that obtains the results of computer learning each time the relationship including the selected housing exterior, the preset parameters, the set housing floor plan, and the set daylighting plan is set.

[0018] With this configuration, the residential floor plan learning unit learns the relationship between the selected residential exterior, pre-set parameters, and the selected residential floor plan each time it is set, and the learning results are updated. Similarly, the daylighting plan learning unit learns the relationship between the selected residential exterior, pre-set parameters, the selected residential floor plan, and the selected daylighting plan each time it is set, and the learning results are updated.

[0019] A preferred configuration is one in which the pre-set parameters include at least one of the following: family composition, site information, layout plan, building regulations information, and desired floor plan.

[0020] With this configuration, at least one of the following parameters—family structure, site information, layout plan, building regulations information, and desired floor plan—is included in the pre-set parameters, allowing for the selection of more appropriate housing floor plan and lighting plan options.

[0021] In a preferred configuration, multiple house exteriors that can be selected as wooden houses are displayed on the display device in a selectable manner, candidate house floor plans are displayed on the display device in a selectable manner, one selected house floor plan is displayed on the display device in a modifiable manner, candidate daylighting plans are displayed on the display device in a selectable manner, and one selected daylighting plan is displayed on the display device in a modifiable manner.

[0022] According to such a configuration, on the display device, a plurality of appearances that can be selected as wooden houses are displayed selectably, floor plan candidates are displayed selectably, the set floor plan is displayed so as to be modifiable, daylighting plan candidates are displayed selectably, and the set daylighting plan is displayed so as to be modifiable.

[0023] As a preferable configuration, the plurality of house appearances that can be selected as the wooden house include the design information necessary for the structural calculation in the information of the wall surface constituting the house appearance.

[0024] According to such a configuration, since the information of the wall surface constituting the house appearance includes the design information necessary for the structural calculation, the safety can be calculated from the selected house appearance.

Effect of the Invention

[0025] According to the present invention, by selecting the appearance of the house, it becomes possible to ensure the safety of the structure required for a wooden house.

[0027] Referring to Figures 1 to 11, one embodiment of a wooden house design support system, a wooden house design support device, and a wooden house design support method will be described. In this embodiment, the wooden house is designed as 3D information using 3D CAD, and BIM data is used as the 3D information. For example, BIM is an abbreviation for Building Information Modeling.

[0028] As shown in Figure 1, the wooden house design support system has, as an example of its processing procedure, a site information setting step (step S90), a house exterior setting step (step S100), a parameter setting step (step S110), a house floor plan candidate selection step (step S120), a house floor plan setting step (step S130), a material specification selection step (step S137), and a structural calculation preliminary step (step S138). The wooden house design support system also includes, as an example of its processing procedure, a daylighting plan candidate selection step (step S140), a daylighting plan setting step (step S150), a structural calculation step (step S157), a drawing creation step (step S170), and a cost estimation step (step S190).

[0029] The site information setting process (step S90) is a process in which various conditions, such as site information for the set wooden house and building regulation information corresponding to the site, are set as parameters. As information required for setting the exterior appearance of the house, site information may include site area and shape, and building regulation information may include thermal insulation performance, snow load, seismic performance, and zoning. Site information may also include the layout plan.

[0030] The house exterior design setting process (step S100) is the process in which the exterior appearance of the wooden house to be built is set by the client or other relevant parties.

[0031] The parameter setting process (step S110) is a process in which various conditions such as the family structure of the residents and their desired floor plan for the wooden house are set as parameters.

[0032] Furthermore, the process of selecting a residential floor plan candidate (step S120) is the process of selecting a floor plan candidate that can correspond to the wooden house selected based on its exterior.

[0033] The house floor plan setting process (step S130) is the process in which a house floor plan is set that can be modified by the client or other party based on the floor plan selected from the candidate floor plans.

[0034] The material specification selection process (step S137) is the process of selecting specifications for exterior elements such as roofs and exterior walls of wooden houses, as well as interior elements such as interior walls and floors, which are related to the load-bearing structure of the building, and interior elements that are not related to the load-bearing structure.

[0035] The structural calculation preliminary step (step S138) is a process in which preliminary structural calculations are made to evaluate the safety of a house based on the set exterior appearance and floor plan of the house.

[0036] The daylighting plan candidate selection process (step S140) is the process of selecting candidate daylighting plans that can correspond to the set house floor plan.

[0037] The daylighting plan setting process (step S150) is the process in which a daylighting plan is set and selected, which can be modified by the client or other party based on the daylighting plan selected from the candidate daylighting plans.

[0038] The structural calculation process (step S157) is a process in which structural calculations are performed to evaluate the safety of the house based on the set exterior appearance, floor plan, and daylighting plan of the house.

[0039] Furthermore, the drawing process (step S170) is the process of creating 3D drawings and images based on the set exterior, floor plan, daylighting plan, and material specifications of the house. In the wooden house design support method, the wooden house is designed using 3D drawing data based on the set exterior, floor plan, daylighting plan, and material specifications of the house. In addition, a 3D image of the wooden house to be built can be obtained from the 3D drawing data, and the accuracy of cost estimation for construction can be improved. As a result, it becomes possible to design and construct wooden houses that satisfy customers.

[0040] The cost estimation process (step S190) is the process of estimating the costs required to construct a wooden house based on the set exterior design, floor plan, lighting plan, and material specifications.

[0041] As shown in Figure 2, the wooden house design support system 10 is connected to a network NW capable of transmitting information. Multiple information processing devices are connected to the network NW in a way that enables information communication. Examples of information processing devices include computers, servers, and tablet terminals. The multiple information processing devices include the design support server 11, client terminals 21 and 31, the client terminal 41, the construction company terminal 51, and the construction company terminal 61.

[0042] For example, the design support server 11 included in the wooden house design support system 10 is equipped with an input unit 12 and an output unit 13.

[0043] The input unit 12 receives input information and communication information, such as information from a keyboard, mouse, touch panel, microphone, and communication information between computers.

[0044] The output unit 13 outputs information such as images and audio, as well as communication information. For example, it outputs images to the screen, audio, and communication information between computers.

[0045] Similar to the input unit 12 of the design support server 11, the input units 22 of the customer terminal 21, 32 of the customer terminal 31, 42 of the client terminal 41, 52 of the construction company terminal 51, and 62 of the construction company terminal 61 receive information through operation or information communication, so a detailed explanation will be omitted.

[0046] The output units 23 of the trading partner terminal 21, 33 of the trading partner terminal 31, 43 of the client terminal 41, 53 of the construction company terminal 51, and 63 of the construction company terminal 61 only need to have at least one of the functions exemplified in the output unit 13 of the design support server 11; a detailed explanation is omitted.

[0047] Each input unit 22, 32, 42, 52, and 62 receives information communication from the output unit 13 of the design support server 11, and information such as images and sounds based on the input communication information may be output from each output unit 23, 33, 43, 53, and 63.

[0048] Alternatively, each input unit 22, 32, 42, 52, and 62 may output the input operation information as communication information from each output unit 23, 33, 43, 53, and 63, and the outputted communication information may be input to the design support server 11 from the input unit 12 of the design support server 11.

[0049] As shown in Figure 3, the design support server 11 comprises an input unit 12, an output unit 13, and an information processing device 14. The information processing device 14 is the part of the design support server 11 that performs information processing functions, and for example, it has a central processing unit, volatile memory, non-volatile memory, and an input / output interface. The input / output interface is connected to the input unit 12, the output unit 13, and the storage unit 200, etc., in a way that enables information communication.

[0050] The design support server 11 includes a house exterior setting unit 100, a structural calculation unit 101, a parameter setting unit 110, a house floor plan candidate selection unit 120, a house floor plan setting unit 130, a daylighting plan candidate selection unit 140, a daylighting plan setting unit 150, a material specification selection unit 160, a house floor plan learning unit 310, and a daylighting plan learning unit 320. The house exterior setting unit 100, the structural calculation unit 101, the parameter setting unit 110, the house floor plan candidate selection unit 120, the house floor plan setting unit 130, the daylighting plan candidate selection unit 140, the daylighting plan setting unit 150, the material specification selection unit 160, the house floor plan learning unit 310, and the daylighting plan learning unit 320 may be functions realized by program processing in the information processing device 14.

[0051] The design support server 11 has a storage unit 200 consisting of internal storage, external storage, or a combination thereof. The storage unit 200 can be accessed, added to, and deleted by the information processing device 14.

[0052] The memory unit 200 stores residential exterior data 210 including design information, parameters 220, residential floor plan data 230, daylighting plan data 240, material specification data 250, 3D design data 260, and training data 290.

[0053] The input unit 12 is the part where the design support server 11 inputs various types of information. More specifically, the input unit 12 receives information from a user interface where information is input based on human operation, or from an interface where information is input via communication, etc. The input unit 12 may also include at least one input device such as a keyboard, mouse, touch panel, microphone, or various sensors.

[0054] In this embodiment, the input unit 12 includes an input device that allows for selection and modification instructions corresponding to the house exterior setting unit 100, structural calculation unit 101, parameter setting unit 110, house floor plan candidate selection unit 120, house floor plan setting unit 130, daylighting plan candidate selection unit 140, daylighting plan setting unit 150, and material specification selection unit 160.

[0055] The input device, corresponding to the house exterior setting unit 100, allows the user to select at least one house exterior from a selection of selectable wooden house exteriors. The input device, corresponding to the house floor plan candidate selection unit 120, allows the user to select at least one house floor plan from a selection of available house floor plan candidates. The input device, corresponding to the house floor plan setting unit 130, may be configured to allow the user to modify a house floor plan that is displayed in a modifiable state. The input device, corresponding to the daylighting plan candidate selection unit 140, may be configured to allow the user to select a daylighting plan candidate that is displayed in a selectable state. The input device, corresponding to the daylighting plan setting unit 150, may be configured to allow the user to modify a daylighting plan that is displayed in a modifiable state.

[0056] The output unit 13 is the part of the design support server 11 that outputs various types of information. More specifically, the output unit 13 outputs information from a user interface that outputs human-recognizable information such as images and sounds, or from an interface that outputs information via communication. The output unit 13 may also include at least one output device, such as a monitor that outputs images or a speaker that outputs sound.

[0057] In this embodiment, the output unit 13 includes a display device that displays information from the house exterior setting unit 100, structural calculation unit 101, parameter setting unit 110, house floor plan candidate selection unit 120, house floor plan setting unit 130, daylighting plan candidate selection unit 140, daylighting plan setting unit 150, and material specification selection unit 160 as images as needed.

[0058] The display device may, in correspondence with the house exterior setting unit 100, display multiple house exteriors that can be selected as wooden houses. In this case, the multiple house exteriors that can be selected as wooden houses include design information necessary for structural calculations in the information of the wall surfaces that constitute the house exterior. The display device may also, in correspondence with the house floor plan candidate selection unit 120, display house floor plan candidates. The display device may also, in correspondence with the house floor plan setting unit 130, display the selected house floor plan in a modifiable manner. The display device may also, in correspondence with the daylighting plan candidate selection unit 140, display daylighting plan candidates. The display device may also, in correspondence with the daylighting plan setting unit 150, display one selected daylighting plan in a modifiable manner.

[0059] The residential exterior setting unit 100 is configured with one residential exterior selected from among a plurality of residential exteriors that can be selected as wooden houses. The single residential exterior configured by selection is also called the selected residential exterior. For example, the residential exterior setting unit 100 is configured by selection with one residential exterior from among a plurality of residential exteriors that can be selected as wooden houses and are displayed as selectable on the display device (residential exterior setting process).

[0060] The residential exterior setting unit 100 may also display multiple selectable residential exteriors on the display device.

[0061] Furthermore, in this embodiment, each of the exterior features of a house, such as the exterior of the selected house, includes design information necessary for structural calculations used to determine the structural safety.

[0062] The structural calculation unit 101 performs structural calculations to evaluate the safety of a wooden house based on the exterior housing data 210, which includes design information about the exterior of the selected house. The structural calculation unit 101 can perform a preliminary structural calculation. In the preliminary structural calculation, the calculation is performed based on the information contained in the exterior housing of the selected house and the building load determined by the material specifications. In addition, the structural calculation unit 101 performs structural calculations that include the load of partitions, the weight of the building, and the location of load-bearing walls as conditions. Results indicating structural safety can be obtained from the structural calculation results based on the design information by the structural calculation unit 101. The structural calculation unit 101 may also perform wall quantity calculations along with structural calculations.

[0063] The parameter setting unit 110 can set information necessary for the construction of a wooden house in the parameter 220. Information that can be set in the pre-configured parameter 220 includes, for example, site information and corresponding building regulations, various conditions such as the layout plan, as well as family composition, site information, and desired floor plan. Note that parameter 220 is a section where multiple parameters are stored.

[0064] The residential floor plan candidate selection unit 120 selects one or more residential floor plans from among a plurality of pre-stored residential floor plans based on pre-set parameters as residential floor plan candidates. More specifically, the residential floor plan candidate selection unit 120 selects residential floor plan candidates based on the relationship between the exterior of the selected house, pre-set parameters, and the plurality of pre-stored residential floor plans. Alternatively, the residential floor plan candidate selection unit 120 may select residential floor plan candidates based on conditions for selecting residential floor plan candidates obtained by reflecting the results of computer learning in the relationship including the exterior of the selected house, pre-set parameters, and the selected residential floor plan. In other words, it may predict and select residential floor plan candidates by applying an algorithm generated using machine learning.

[0065] The residential floor plan setting unit 130 sets a designated residential floor plan based on one of the residential floor plan candidates consisting of one or more residential floor plans corresponding to the selected residential exterior, and the designated residential floor plan is one that can be modified after selection. The residential floor plan setting unit 130 may also set the designated residential floor plan on the condition that the structural safety is obtained from the results of structural calculations based on the design information of the selected residential exterior.

[0066] The daylighting plan candidate selection unit 140 selects one or more daylighting plans from a plurality of pre-stored daylighting plans based on the floor plan of the designated house as daylighting plan candidates. The daylighting plan candidate selection unit 140 selects daylighting plan candidates based on the relationship including the exterior of the designated house, pre-set parameters, the floor plan of the designated house, and the designated daylighting plan. The daylighting plan candidate selection unit 140 may also select daylighting plan candidates based on conditions for selecting daylighting plan candidates obtained by reflecting the results of computer learning in the relationship including the exterior of the designated house, pre-set parameters, the floor plan of the designated house, and the designated daylighting plan. In other words, it may apply an algorithm generated using machine learning to predict and select daylighting plan candidates.

[0067] The daylighting plan setting unit 150 sets a daylighting plan based on a daylighting plan selected from one or more daylighting plan candidates corresponding to the floor plan of the house to be set, which was made modifiable after selection.

[0068] The material specification selection unit 160 selects materials based on the 3D data, which is the design information. The materials selected by the material specification selection unit 160 may include those related to the building's load, such as exteriors like roofs and exterior walls, interiors like interior walls and floors, as well as floors, walls, and equipment. In other words, materials and specifications may be selected for structural parts of a wooden house, or for non-structural parts of a wooden house.

[0069] The data stored in the memory unit 200 will now be described.

[0070] The residential exterior data 210 is associated with one or more residential exterior data sets that can be selected as wooden houses, and various data corresponding to wooden houses determined from the residential exterior. As mentioned above, the residential exterior data 210 uses BIM data as 3D information, but 3D information may also be referenced from 3D design data 260, etc. The residential exterior data 210 may also directly contain 3D information. Furthermore, the data associated with the residential exterior data 210 pertains to wooden houses for which a predetermined seismic resistance rating, for example, seismic resistance rating 3, has been secured as a result of structural calculations to evaluate the safety of the house in advance. Furthermore, the data associated with the residential exterior data 210 may be data for which structural calculations can be performed, and may also have a selectable seismic resistance rating.

[0071] Figure 4 shows an example of how the residential exterior data 210 is presented in the residential exterior selection table T40. For example, the residential exterior data 210 includes the following data items for each product, as shown in the residential exterior selection table T40: product name C41, concept C42, product building (design) C43, UA value C44, area C45, estimated area in tsubo C46, ​​preference C47, cost C48, and selling price C49. The residential exterior selection table T40 is a list of the concepts C42, product building (design) C43, UA value C44, area C45, estimated area in tsubo C46, ​​preference C47, cost C48, and selling price C49 that correspond to each product name C41 included in the residential exterior data 210.

[0072] Product names C41 used to distinguish products include Type A 211, Type B 212, Type C 213, Type D 214, Type E 215, and Type F 216. For example, the correspondence between data items and content for Type A 211 is as follows: Concept C42 is "Freedom", Product Building (Design) C43 is illustrated, UA value C44 is "a1", Area C45 is "a2", Estimated Square Footage C46 is "a3", Taste C47 is "a4", Cost C48 is "a5", and Selling Price C49 is "a6".

[0073] Since Type B 212 to Type F 216 have the same data items as Type A 211, they will be explained in the same order as Type A 211.

[0074] In other words, in type B 212, the content in the order of the data items is "Simple", "Illustration", "b1", "b2", "b3", "b4", "b5", and "b6". Similarly, in type C 213, the content in the order of the data items is "Narrow", "Illustration", "c1", "c2", "c3", "c4", "c5", and "c6".

[0075] Similarly, in type D 214, the content in the order of the data items is "Durability", illustrated, "d1", "d2", "d3", "d4", "d5", "d6". Similarly, in type E 215, the content in the order of the data items is "Courtyard", illustrated, "e1", "e2", "e3", "e4", "e5", "e6". Similarly, in type F 216, the content in the order of the data items is "Insulation", illustrated, "f1", "f2", "f3", "f4", "f5", "f6".

[0076] Taking Type A 211 as an example, in the data items, "a1" is "0.55", "a2" is "70.50 square meters~", "a3" is "39.75 square meters~", "a4" is "People with strong hobbies and preferences", "a5" is "8.3 million yen~", and "a6" is "11.1 million yen~".

[0077] Furthermore, taking the data item preference C47 as an example, "b4" for type B 212 means "cost-oriented," "c4" for type C 213 means "urban-oriented," "d4" for type D 214 means "durability-oriented," "e4" for type E 215 means "privacy-oriented," and "f4" for type F 216 means "performance-oriented."

[0078] Furthermore, the residential exterior data 210 includes data (design information) that can be used to assess the safety of the house, as well as data corresponding to column and wall layout plans, cross-sectional drawings, and various other layout plans.

[0079] Figure 5 shows an example of a column and wall layout plan 21A for the first floor of a two-story wooden house, which has Y0 to Y8 directions in the Y direction and X0 to X8 directions in the X direction. The column and wall layout plan 21A is a drawing that shows the arrangement of columns and walls of a wooden house in a plan view, and is drawn based on the design information included in the house exterior data 210.

[0080] The column and wall layout plan 21A includes symbols that identify the building material of each column, and the identified building material contains information that enables structural calculations for wooden houses. This information includes, for example, specification data necessary for structural calculations for building materials with a proven track record of use. Building materials with a proven track record of use may have their data stored and accumulated as materials to be reused. In other words, design information used for structural calculations can be obtained from the house exterior data 210.

[0081] Furthermore, the residential exterior data 210 includes design information for the wall sections, which are building materials placed in the column spacing C51-C58 in the Y direction and R51-R58 in the X direction. This wall section design information also includes design information that enables structural calculations for wooden houses.

[0082] Furthermore, based on the design information included in the residential exterior data 210, the necessary drawings for a two-story wooden house can be created. Examples of necessary drawings include the second-floor column and wall layout plan, section view (X direction), section view (Y direction), floor plan (first floor), floor plan (second floor), floor plan (roof), foundation plan, simplified frame plan (Y0 direction), simplified frame plan (Y8 direction), simplified frame plan (X0 direction), simplified frame plan (X2 direction), and simplified frame plan (X8 direction).

[0083] Incidentally, the wooden house shown by the residential exterior data 210 of this embodiment ensures the structural safety required for a wooden house. More specifically, the residential exterior data 210 includes specification data for the columns and exterior walls located along Y0, Y8, X0, and X8, and for the columns located at the intersection of X4 and Y4. Based on this included specification data, the structural safety required for a wooden house can be calculated.

[0084] Referring to Figure 3, parameter 220 includes various conditions for the wooden house to be built.

[0085] Figure 6 shows an example of parameter 220. For example, parameter 220 includes site information 221, building regulations information 222, site plan information 223, resident family composition 225, desired house layout 226, life plan information 227, and daily living flow 228 as conditions related to the design of a wooden house.

[0086] Referring to Figure 3, the house floor plan data 230 includes data for one or more house floor plans corresponding to wooden houses. Specifically, the house floor plan data 230 includes candidate house floor plans consisting of one or more house floor plans corresponding to the house exterior data 210 (house exterior). In other words, the house floor plan data 230 includes one or more house floor plans that can be proposed for one product name C41 shown in the house exterior selection table T40 (see Figure 4).

[0087] Furthermore, the housing floor plans included in the housing floor plan data 230 include at least one of the extraction conditions used to propose a desirable housing floor plan, such as the family composition of the residents 225, the desired housing floor plan 226, life plan information 227, and daily living flow 228.

[0088] Furthermore, the housing floor plan data 230 may be updated by adding, as appropriate, designated housing floor plans that have been modified or changed based on one housing floor plan selected from the housing floor plan candidates.

[0089] Furthermore, in this embodiment, the residential floor plan data 230 may be updated with the results learned by the residential floor plan learning unit 310 based on the set residential floor plan.

[0090] Referring to Figure 3, the daylighting plan data 240 includes data for one or more daylighting plans corresponding to the floor plan of a wooden house. Specifically, the daylighting plan data 240 includes candidate daylighting plans consisting of one or more daylighting plans corresponding to the floor plan of the house being set. In other words, the daylighting plan data 240 includes one or more daylighting plans that can be proposed for one product name C41 shown in the house exterior selection table T40 (see Figure 4). The daylighting plans included in the daylighting plan data 240 include the legally required minimum window size, which is the lower limit of the window size required for a living room.

[0091] Furthermore, the daylighting plan data 240 includes at least one of the extraction conditions used to propose a favorable daylighting plan, such as the family composition of the residents 225, the desired house layout 226, life plan information 227, and daily life flow 228.

[0092] Furthermore, the daylighting plan data 240 may be updated by appropriately adding a set daylighting plan that has been modified or changed based on one daylighting plan selected from the daylighting plan candidates. In addition, in this embodiment, the daylighting plan data 240 may be updated with the results learned by the daylighting plan learning unit 320 based on the set daylighting plan.

[0093] Material specification data 250 includes data corresponding to specifications for building loads, such as exteriors like roofs and exterior walls of wooden houses, and interiors like interior walls and floors, as well as specifications for interiors that are not related to building loads. It may also include visual information corresponding to interiors to support the creation of 3D images. Material specification data 250 includes, for example, data for roofing materials, floors, walls, and equipment. For example, roofing material data includes specifications for tile type, dimensions, and weight. Floor data includes dimensions, weight, and specifications for floorboards. Wall data includes wall materials for interior and exterior use, their dimensions, weight, and specifications, as well as dimensions and specifications for wallpaper. Equipment data includes dimensions, weight, specifications, accessories, and installation conditions for equipment. Material specification data 250 may also include data related to building loads necessary for structural calculations, and visual data necessary for appearance.

[0094] The 3D design data 260 is design data for 3D CAD corresponding to a wooden house. The 3D design data 260 is data for a wooden house designed in 3D CAD using accumulated BIM data. In this embodiment, the 3D design data 260 may also be referenced from the house exterior data 210. Furthermore, the 3D design data 260 may be referenced from the parameters 220, house floor plan data 230, daylighting plan data 240, and material specification data 250 as needed.

[0095] BIM data is a collection of objects corresponding to elements such as building materials. Therefore, BIM data contains design information necessary for structural calculations used to determine the structural safety of wooden houses. Specifically, BIM data may include information on building material parts, such as dimensions like width, depth, height, and weight, as well as specifications such as materials and performance, assembly processes, and assembly man-hours. In other words, a wooden house designed with BIM data contains a lot of data in addition to drawing information, and can also reference a lot of other data.

[0096] Furthermore, because BIM data has a structural shape, it can be reproduced as a 3D image. Additionally, BIM data may include the appearance (surface) of building materials, and the exterior and interior can be reproduced as 3D images. BIM data may also include equipment and fixtures, including part numbers, manufacturers, and prices.

[0097] Thus, BIM data includes information such as the materials and specifications of building materials and equipment, making it possible to perform maintenance and management.

[0098] The training data 290 is used to train the residential floor plans included in the residential floor plan data 230 and the daylighting plans included in the daylighting plan data 240. The training data 290 includes the residential floor plans set in the residential floor plan setting unit 130 and the daylighting plans set in the daylighting plan setting unit 150.

[0099] The training data 290 retains the assigned house floor plans until training corresponding to at least the house floor plan data 230 is completed, and the trained data may be deleted according to predetermined conditions. Similarly, the training data 290 retains the assigned daylighting plans until training corresponding to at least the daylighting plan data 240 is completed, and the trained data may be deleted according to predetermined conditions.

[0100] More specifically, the floor plans of the selected houses in the training data 290 may be computer-learned by the house floor plan learning unit 310 each time a relationship is established that includes the exterior of the selected house, pre-set parameters, and the floor plans of the selected houses, and the house floor plans based on the results of the computer learning may be included in the house floor plan data 230.

[0101] Furthermore, the daylighting plan among the learning data 290 may be subjected to computer learning of the daylighting plan by the daylighting plan learning unit 320 each time a relationship is established that includes the exterior of the selected house, pre-set parameters, the floor plan of the house, and the daylighting plan, and the daylighting plan based on the results of the computer learning may be included in the daylighting plan data 240.

[0102] Next, an example of the processing procedure in the wooden house design support method executed by the wooden house design support system 10 will be explained based on a flowchart.

[0103] Figure 1 shows a flowchart illustrating the outline of the wooden house design support method. In the wooden house design support system 10, the wooden house design support method is performed based on various information processing in the design support server 11.

[0104] First, the design support server 11 receives site information from the input unit 12, etc. (site information setting process: step S90). The design support server 11 sets various conditions of site information and building regulation information in parameter 220. For example, the parameter items may be set by displaying the parameter items on the display device as shown in parameter 220 in Figure 6. If the land on which to build the wooden house has not been decided, information on the desired site may be entered.

[0105] Prior to the house exterior setting process (step S100 in Figure 1), the design support server 11 enables the selection of a house exterior via the input unit 12 by displaying multiple selectable house exteriors for wooden houses on the display device of the output unit 13. The multiple selectable house exteriors for wooden houses are house exteriors that comply with laws and regulations related to the set site information. For example, the house exterior selection table T40 shown in Figure 4 is displayed on the display device.

[0106] Incidentally, each of the multiple house exteriors that can be selected as wooden houses by the design support server 11 has undergone structural calculations to evaluate the safety of the house. Therefore, when the design support server 11 makes a selection, a house exterior that corresponds to the site information and ensures the safety of the house for that site is selected, and the system can proceed to the next step. On the other hand, house exteriors that do not correspond to the site information or that do not ensure the safety of the house for that site are not selected, and the system cannot proceed to the next step. In the event of slight numerical deficiencies or partial non-conformities, the system may proceed to the next step after processing necessary to ensure safety, such as notification, re-selection of the house exterior, or approval from an architect. Furthermore, when setting the house exterior, the system may perform an estimate of the structural calculations, and if the estimate is appropriate, the system can proceed to the next step; if it is inappropriate, the system cannot proceed to the next step.

[0107] In the design support server 11, the exterior of the wooden house selected as the building target by the client, etc., is set (house exterior setting process: step S100 in Figure 1). For example, by operating the house exterior selection table T40 (see Figure 4) displayed on the display device via the input unit 12, the selected house exterior is selected and set as one of the house exteriors selected from the product name C41.

[0108] Furthermore, in the design support server 11, various conditions such as the family structure and requests of the residents corresponding to the selected exterior of the house are set in parameter 220 (parameter setting process: step S110 in Figure 1). In the parameter setting process, various conditions such as the family structure and requests of the residents are input and set as parameter items from the input unit 12, etc. For example, the parameter items may be set by displaying the parameter items on the display device as shown for parameter 220 in Figure 6.

[0109] Referring to Figure 1, the design support server 11 selects a candidate house floor plan corresponding to the selected house exterior set in the house exterior setting step (house floor plan candidate selection step: step S120 in Figure 1).

[0110] Referring to Figure 7, a flowchart showing an example of the housing floor plan candidate selection process (step S120 in Figure 1) includes the layout planning process (step S121 in Figure 7), the housing floor plan condition calculation process (step S122 in Figure 7), the exterior appearance determination process for the selected housing (step S123 in Figure 7), and the housing floor plan candidate extraction process (step S124 in Figure 7).

[0111] In the site planning process (step S121 in Figure 7), site plan information 223 is obtained as a site plan that determines where on the site the building will be placed, based on the exterior appearance of the selected house and the site information 221 and building regulation information 222. The site plan determines the length, width, and orientation of the building. In addition, in the site planning process, the site plan information 223 that was previously determined may be updated to an appropriate site plan information 223 by referring to it.

[0112] In the process of calculating the conditions for a residential floor plan (step S122 in Figure 7), the "conditions for extracting a suitable residential floor plan" are calculated based on the site plan information 223, the resident's family structure 225, desired residential floor plan 226, life plan information 227, and daily life flow 228.

[0113] In the process of determining the exterior appearance of the selected house (step S123 in Figure 7), the floor plan corresponding to the exterior appearance of the selected house is determined from the house floor plan data 230.

[0114] In the process of extracting candidate house floor plans (step S124 in Figure 7), house floor plans that meet or are close to the "conditions for extracting a suitable house floor plan" are extracted from among the house floor plans corresponding to the exterior of the selected house.

[0115] Referring to Figure 1, the design support server 11 sets the selected house floor plan from the candidate house floor plans as the selected house floor plan (house floor plan setting process: step S130 in Figure 1). Note that the selected house floor plan can be modified by the client after it has been selected from the candidate house floor plans, so it may be the same as the selected house floor plan or it may have been modified.

[0116] Referring to Figure 8, a flowchart showing an example of the house floor plan setting process includes a house floor plan candidate output process (step S131 in Figure 8), a house floor plan selection process (step S132 in Figure 8), a house floor plan adjustment process (step S133 in Figure 8), and a house floor plan determination process (step S134 in Figure 8).

[0117] In the process of outputting candidate house floor plans (step S131 in Figure 8), the candidate house floor plans that can be selected by the homeowner are displayed on the display device.

[0118] In the house floor plan selection process (step S132 in Figure 8), one candidate is selected and set by the homeowner or other party from the house floor plan candidates displayed on the display device.

[0119] In the house floor plan modification process (step S133 in Figure 8), the selected and set house floor plan is displayed in a way that allows the homeowner to modify it, and the homeowner can also modify the house floor plan through the operating device.

[0120] In the process of determining the house layout (step S134 in Figure 8), the house layout that could be modified by the client, etc., through the operating device is determined as the selected house layout. Once the layout is determined, the amount of natural light required for each room is also determined.

[0121] Referring to Figure 1, the design support server 11 selects the specifications for materials for a wooden house (material specification selection process: step S137 in Figure 1). For example, the design support server 11 enables material selection through the input unit 12 by displaying the materials included in the material specification data 250 on the display device of the output unit 13. The display device may display, for example, text information, charts, or photographs. The materials include exterior materials such as roofs and exterior walls, and interior materials such as interior walls and floors, which are related to the load on the building, and the conditions related to the load on the building are met in the material specification selection process.

[0122] Furthermore, the design support server 11 performs preliminary structural calculations to evaluate the safety of the house based on the configured exterior and floor plan (preliminary structural calculation process: step S138 in Figure 1).

[0123] In the preliminary structural calculation process (step S138 in Figure 1), the design support server 11 estimates the structural calculations to evaluate the safety of the selected house based on the house exterior data 210 and the selected house floor plan, assuming that the conditions for the floor plan and elevation plan are met. In the preliminary structural calculation process, if the structural calculation results show that the safety of the house is ensured, the system can proceed to the next step. On the other hand, if the safety of the house is not ensured in the preliminary structural calculation process, the system cannot automatically proceed to the next step. Instead, it is notified, and necessary processes to ensure safety are carried out, such as re-selecting the house exterior or obtaining permission from an architect. Here, safety is considered ensured if, for example, the seismic resistance level is 3 or higher, and not ensured otherwise. The numerical level of safety may be changed.

[0124] The design support server 11 selects candidate daylighting plans that correspond to the selected residential floor plan set in the residential floor plan setting process (daylighting plan candidate selection process: step S140 in Figure 1). In the daylighting plan candidate selection process, daylighting plan candidates are selected so as to be able to present the minimum legally required window size in the living rooms.

[0125] Referring to Figure 9, a flowchart showing an example of the daylighting plan candidate selection process (step S140 in Figure 1) includes the daylighting plan condition calculation process (step S141 in Figure 9) and the daylighting plan extraction process (step S142 in Figure 9).

[0126] In the process of calculating the conditions for the daylighting plan (step S141 in Figure 9), the "conditions for extracting a suitable daylighting plan" are calculated based on the selected housing floor plan, the resident's family composition 225, desired housing floor plan 226, life plan information 227, and daily life flow 228.

[0127] In the daylighting plan extraction process (step S142 in Figure 9), daylighting plans that meet or closely match the "conditions for extracting a suitable daylighting plan" are extracted from among the daylighting plans corresponding to the selected house layout.

[0128] Referring to Figure 1, the design support server 11 sets the daylighting plan selected from the daylighting plan candidates as the set daylighting plan (daylighting plan setting process: step S150 in Figure 1). Note that the set daylighting plan can be modified by the client after it has been selected from the daylighting plan candidates, so it may be the same as the selected daylighting plan, or it may have been modified to the extent that it does not fall below the legally required minimum. It may also be possible to prevent settings that fall below the legally required minimum, or to notify the client of such a setting.

[0129] Referring to Figure 10, a flowchart showing an example of the daylighting plan setting process includes a daylighting plan candidate output process (step S151 in Figure 10), a daylighting plan selection process (step S152 in Figure 10), a daylighting plan adjustment process (step S153 in Figure 10), and a daylighting plan determination process (step S154 in Figure 10).

[0130] In the daylighting plan candidate output process (step S151 in Figure 10), the daylighting plans that the client can select are displayed on the display device.

[0131] In the daylighting plan selection process (step S152 in Figure 10), one candidate is selected and set by the client or other party from the daylighting plan candidates displayed on the display device.

[0132] In the daylighting plan modification process (step S153 in Figure 10), the selected daylighting plan is displayed in a way that allows the client to modify it, and the client can modify the daylighting plan through the operating device. Specifically, windows can be added to non-residential rooms that are not legally required, or windows in residential rooms can be enlarged. Initially, the minimum window size required for a room is presented, so the window size can be enlarged or reduced within a range that does not fall below the initially presented window size.

[0133] In the daylighting plan determination process (step S154 in Figure 10), the daylighting plan that could be modified by the client, etc., through the operating device is determined as the set daylighting plan.

[0134] Furthermore, once the daylighting plan has been set, the design support server 11 performs structural calculations to evaluate the safety of the selected house's exterior (structural calculation process: step S157 in Figure 1). Here, structural calculations can be performed for the wooden house to be constructed based on the set floor plan, material specifications, and set daylighting plan. In addition, highly accurate structural calculations can be performed for the house because at least the loads of the partitions are determined based on the set floor plan, at least the weight of the building is determined by the material specifications, and at least the location of the load-bearing walls is determined based on the set daylighting plan.

[0135] Furthermore, the design support server 11 creates drawings based on 3D data derived from the selected exterior of the house, the set floor plan of the house, the set daylighting plan, and the selected material specifications (drawing process: step S170 in Figure 1). For example, in the drawing process, 3D drawings for design and construction may be created, or 3D images for checking the finished product may be created. The 3D drawings and 3D images may be images displayed on a computer screen, or AR images and VR images provided using AR or VR video equipment.

[0136] Furthermore, the design support server 11 calculates the cost required to construct a wooden house based on the selected exterior of the house, the specified floor plan of the house, the specified daylighting plan, and the material specifications (calculation process: step S190 in Figure 1).

[0137] Then, based on the selected exterior design, the specified floor plan, the specified lighting plan, and the material specifications, a wooden house is designed using 3D CAD and BIM data, and construction is carried out based on that design.

[0138] (Learning process)

[0139] Incidentally, as shown in Figure 3, the wooden house design support system 10 may have a learning process for learning. In this case, the design support server 11 performs machine learning (computer learning) as the learning process. In the learning process, the design support server 11 learns about house floor plans using the house floor plan learning unit 310, and learns about daylighting plans using the daylighting plan learning unit 320.

[0140] Generally, machine learning is a technology that gives computers functions such as learning ability, where the computer autonomously generates the conditions necessary for judgment, such as data identification, from pre-acquired training data. In this embodiment, machine learning is performed to enable the selection of more appropriate candidates by reflecting data modified by the homeowner, etc., in the selection of home floor plan candidates by the home floor plan candidate selection unit 120 and the selection of daylighting plan candidates by the daylighting plan candidate selection unit 140. Furthermore, machine learning may be used to update the data for home floor plan candidates and daylighting plan candidates to more appropriate data by reflecting data modified by the homeowner, etc.

[0141] The residential floor plan learning unit 310 performs computer learning on the residential floor plan each time a residential floor plan to be set is configured. The residential floor plan learning unit 310 may also computer learn the relationship between the selected residential exterior, pre-set parameters, and the configured residential floor plan, which are used by the residential floor plan candidate selection unit 120 when selecting a residential floor plan candidate, and the results of this learning may be made available to the residential floor plan candidate selection unit 120.

[0142] The daylighting plan learning unit 320 performs computer learning on the daylighting plan each time a daylighting plan to be set is configured. The daylighting plan learning unit 320 may also learn the relationships between the exterior of the selected house, which is used as a condition when the daylighting plan candidate selection unit 140 selects a daylighting plan candidate, pre-set parameters, the floor plan of the house to be configured, and the daylighting plan to be configured, and the learning results may be made available to the daylighting plan candidate selection unit 140.

[0143] Next, an example of the processing procedure in the learning process performed by the wooden house design support system 10 will be explained based on a flowchart. The design support server 11 learns the conditions for selecting the house layout and the conditions for selecting the daylighting plan.

[0144] Referring to Figure 11, the design support server 11 includes, as an example of the learning process flowchart, the acquisition of the exterior of the selected house (step S301), the acquisition of the setting parameters (step S302), the acquisition of the floor plan of the set house (step S303), and the acquisition of the daylighting plan (step S304). The design support server 11 also includes, as an example of the learning process flowchart, the house floor plan learning process (step S310) and the daylighting plan learning process (step S320).

[0145] In the acquisition of the selected house exterior (step S301), the selected house exterior set in the house exterior setting unit 100 is acquired from memory or house exterior data 210 and stored in the learning data 290.

[0146] In the setting parameter acquisition (step S302), each parameter item when the specified house floor plan is set is acquired from parameter 220 and stored in the learning data 290.

[0147] In acquiring the designated house floor plan (step S303), the designated house floor plan set in the house floor plan setting unit 130 is acquired from memory or house floor plan data 230 and stored in the learning data 290.

[0148] In acquiring the configured daylighting plan (step S304), the configured daylighting plan set in the daylighting plan setting unit 150 is acquired from memory or daylighting plan data 240 and stored as learning data 290.

[0149] In the residential floor plan learning process (step S310), the conditions used by the residential floor plan candidate selection unit 120 when selecting a residential floor plan candidate are learned by the computer based on the relationship between the exterior of the selected house, pre-set parameters, and the set residential floor plan, and the learned results are stored in the storage unit 200 so that they can be used by the residential floor plan candidate selection unit 120. Alternatively, the system may learn that the set residential floor plan stored in the learning data 290 has been modified for the residential floor plan selected from the residential floor plan candidates, and update one or more residential floor plans that will become residential floor plan candidates and store them in the residential floor plan data 230.

[0150] In other words, in the housing floor plan learning process (step S310), each time a housing floor plan is set, the relationship between the set housing floor plan, the selected housing exterior, and the pre-set parameters is learned by the housing floor plan learning unit 310. This allows customer preferences to be reflected based on the track record of housing floor plans used in wooden houses, and improves customer satisfaction in the selection of housing floor plan candidates by the housing floor plan candidate selection unit 120.

[0151] In the daylighting plan learning process (step S320), the daylighting plan candidate selection unit 140 learns the conditions it uses when selecting a daylighting plan candidate based on the relationship between the exterior of the selected house, pre-set parameters, the floor plan of the house to be set, and the set daylighting plan, and stores the learned results in the storage unit 200 so that the daylighting plan candidate selection unit 140 can use them. Alternatively, the system may learn that the set daylighting plan stored in the learning data 290 has been modified for the daylighting plan selected from the daylighting plan candidates, and update one or more daylighting plans that will become daylighting plan candidates and store them in the daylighting plan data 240.

[0152] In other words, in the daylighting plan learning process (step S320), each time a daylighting plan is set, the relationship between the selected house exterior, pre-set parameters, the house layout, and the set daylighting plan is learned by the daylighting plan learning unit 320. This allows the system to reflect customer preferences based on the track record of daylighting plans used in wooden houses, thereby improving customer satisfaction in the selection of daylighting plan candidates by the daylighting plan candidate selection unit 140.

[0153] As described above, the wooden house design support system, wooden house design support device, and wooden house design support method according to this embodiment provide the following effects.

[0154] (1) By performing structural calculations used to determine structural safety based on the design information included in the exterior of the selected house, it becomes possible to obtain the results of structural calculations for wooden houses. The setting of the floor plan of the selected house is then set on the condition that the safety of the wooden house can be obtained from the results of the structural calculations. In other words, the setting of the floor plan of the selected house has very little impact on the safety of the wooden house. This makes it possible to ensure the structural safety required for wooden houses by selecting the exterior of the house.

[0155] In this way, the safety of a wooden house is ensured by the design of its exterior, which reduces the impact of the house layout and lighting plan on the building's safety, thus increasing the freedom of choice in house layouts and lighting plans. As a result, it becomes easier for construction companies to design layouts and lighting plans that provide high customer satisfaction.

[0156] (2) Candidate house floor plans are selected from among several pre-stored house floor plans based on pre-set parameters. This makes it possible to select floor plans that have little impact on the exterior appearance and safety of the house as candidate house floor plans. Candidate daylighting plans are selected from among several pre-stored daylighting plans based on the selected house floor plan. This makes it possible to select daylighting plans that have little impact on the exterior appearance and safety of the house as candidate daylighting plans.

[0157] (3) Since the candidate house floor plans are selected based on the results of computer learning, the candidate house floor plans can be presented to the client as more appropriate based on the selected house exterior, pre-set parameters, and the set house floor plan. Since the candidate daylighting plan is selected based on the results of computer learning, the candidate daylighting plan can be presented to the client as more appropriate based on the relationship including the selected house exterior, pre-set parameters, the set house floor plan, and the set daylighting plan.

[0158] (4) The residential floor plan learning unit 310 learns the relationship between the selected residential exterior, pre-set parameters, and the set residential floor plan each time it is set, and updates the learning results. The daylighting plan learning unit 320 learns the relationship between the selected residential exterior, pre-set parameters, the set residential floor plan, and the set daylighting plan each time it is set, and updates the learning results.

[0159] (5) Since at least one of the following is included in the pre-set parameters: family structure, site information, layout plan, building regulations information, and desired floor plan, the selection of housing floor plan candidates and daylighting plan candidates will be more appropriate.

[0160] (6) The display device of the output unit 13 displays multiple exteriors that can be selected as wooden houses, selectable house floor plan candidates, a set house floor plan that can be modified, selectable daylighting plan candidates, and a set daylighting plan that can be modified.

[0161] (7) Since the information on the wall surfaces that make up the exterior of the house includes the design information necessary for structural calculations, it becomes possible to calculate safety from the selected exterior of the house.

[0162] (Other embodiments)

[0163] The above embodiment can also be implemented in the following manner.

[0164] One or more housing exterior design candidates may be displayed on at least one of the following terminals via information communication with the design support server 11: the output unit 23 of the trading partner terminal 21, the output unit 33 of the trading partner terminal 31, the output unit 43 of the client terminal 41, the output unit 53 of the construction company terminal 51, and the output unit 63 of the construction company terminal 61.

[0165] Through information communication with the design support server 11, at least one of the following may be selected from the list of house exterior candidates: input unit 22 of the trading partner terminal 21, input unit 32 of the trading partner terminal 31, input unit 42 of the client terminal 41, input unit 52 of the construction company terminal 51, and input unit 62 of the construction company terminal 61.

[0166] The housing floor plan candidate selection unit 120 does not necessarily need to immediately reflect the results of computer learning in the conditions for selecting housing floor plan candidates. In this case, an appropriate housing floor plan candidate can be selected within the range of existing settings.

[0167] Furthermore, if the results of computer learning are reflected in the housing floor plan data 230, the housing floor plan candidate selection unit 120 can select housing floor plan candidates in a manner that reflects the results of computer learning.

[0168] The daylighting plan candidate selection unit 140 does not necessarily need to immediately reflect the results of computer learning in the conditions for selecting a daylighting plan candidate. In this case, an appropriate daylighting plan candidate can be selected within the range of existing settings.

[0169] Furthermore, if the daylighting plan data 240 reflects the results of computer learning, the daylighting plan candidate selection unit 140 can select a daylighting plan candidate that reflects the results of computer learning.

[0170] Even in computers that cannot perform computer learning, the results learned by other computers can be reflected in the residential floor plan candidate selection unit 120, the daylighting plan candidate selection unit 140, the residential floor plan data 230, and the daylighting plan data 240. This makes it possible to select residential floor plan candidates and daylighting plan candidates based on the results learned by the computer.

[0171] The example given shows the structural calculation process (step S101 in Figure 1) following the exterior design setting process (step S100 in Figure 1), but the process is not limited to this, and the structural calculation process may be omitted. In other words, if the selected exterior design is selected in the exterior design setting process and results indicating the safety of the house based on structural calculations are obtained, the structural calculation process may be omitted. Even in this case, the floor plan setting unit 130 will set the floor plan of the selected house, provided that results indicating structural safety are obtained from the structural calculation results based on the design information of the selected exterior design.

[0172] The wooden house design support system 10 and the design support server 11 may have some of their functions performed on other computers via a network NW.

[0173] The wooden house design support system 10 may also include terminals connected via a network NW. [Explanation of symbols]
