Description

[Technical Field]

[0001] The present invention relates to an architectural design support device and an architectural design support method that can easily and quickly select and display candidate buildings that can be constructed. [Background technology]

[0002] Conventionally, an architectural design support device that can be used when designing a constructible building is proposed, which displays the target site on which the building will be constructed on a display screen, and can stack and connect a large number of room blocks on this target site to display the constructible building in three dimensions (see Patent Document 1).

[0003] In addition, an architectural design support device has been proposed that displays three-dimensional map information and the target site on which a building is to be constructed superimposed on a display screen, and by inputting desired building conditions such as the building area, number of floors, and floor shape of the building to be constructed, displays a three-dimensional model of the building on the target site, thereby displaying buildings that can be constructed in three dimensions (see Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-209017 [Patent Document 2] Japanese Patent Publication No. 2022-115566 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0005] The architectural design support device described in Patent Document 1 allows even non-architectural design engineers to grasp in three dimensions the buildings that can be constructed on the target site relatively easily and in a short time, but it does not allow the maximum size (volume) of the building to be grasped as a three-dimensional model and is not applicable to design plans.

[0006] On the other hand, the architectural design support device described in Patent Document 2 displays three-dimensional models of buildings that can be constructed on the target site along with three-dimensional map information, and can grasp the maximum size (volume) of the building, but it does not automatically extract candidates for the maximum size (volume) of the building, identify the most suitable building from among them, and apply it to the design plan.

[0007] The present invention has been made in consideration of the above-mentioned conventional problems, and aims to provide an architectural design support device and architectural design support method that can automatically extract a large number of candidates for the maximum size (volume) of a building that can be constructed on a target site in a relatively short time, automatically select from these candidates multiple optimal maximum size (volume) of a building, and can be efficiently applied to building design plans. [Means for solving the problem]

[0008] In order to achieve the above object, the architectural design support device of the present invention comprises an input device, an output device, and a computer main body, The auxiliary storage device (hard disk) of the computer main body stores design support programs, map information data generated by a map information application including three-dimensional models, and building condition data including site conditions such as site area and setback distance, and building conditions such as building volume, floor area, and floor height.

[0009] Here, the design support program is characterized by executing a process for generating a standard-compliant building model, a process for generating a planned building model, a process for evaluating the planned building model, and a process for creating an architectural design support sheet.

[0010] The process of generating the standard-compliant building model is characterized by inputting map information data and building condition data, and obtaining a standard-compliant building model and sky exposure factor measurement point data for each road boundary line.

[0011] The process of generating the planned building model is characterized by determining a cutting plane based on the acquired standard-compliant building model and sky exposure factor measurement point data, automatically cutting, and automatically generating a planned building model that satisfies the sky exposure factor.

[0012] The evaluation process of the planned building model is characterized by calculating and analyzing the exterior image (perspective), volume, floor area, floor height, environmental analysis results, etc. of the planned building model based on the generated planned building model, and displaying and outputting the resulting data.

[0013] In addition, the architectural design support method of the present invention is characterized by inputting map information data and building condition data, acquiring standard-compliant building models and sky exposure factor measurement point data for each road boundary line, determining a cutting surface based on the acquired standard-compliant building models and sky exposure factor measurement point data, automatically cutting, and automatically generating a planned building model that satisfies the sky exposure factor. [Effects of the Invention]

[0014] The architectural design support device of the present invention automatically generates a large number of candidates for the maximum size (volume) of buildings that can be constructed on the target site in a relatively short time, and then automatically selects multiple candidates for the most optimal maximum size (volume) of buildings from these, thereby providing great support in the design and planning of buildings.

[0015] Furthermore, according to the architectural design support device of the present invention, an architectural design support sheet S is created based on various analytical data relating to suitable buildings that can be constructed on the target site. This architectural design support sheet can be displayed on the display 21 and can also be printed and output on paper as appropriate using the printer 22, making it easier to understand visually.

[0017] Hereinafter, preferred embodiments of the architectural design support device of the present invention will be described in detail with reference to the drawings.

[0018] As shown in FIG. 1, the architectural design support device 100 of the present invention comprises an input device 10, an output device 20, and a computer main body 30.

[0019] The input device 10 comprises a keyboard 11, a mouse 12, etc., and the output device 20 comprises a display 21, a printer 22, etc.

[0020] As shown in FIG. 2, the computer main body 30 is made up of a control device 31, an arithmetic unit 32, a main memory 33, an auxiliary memory device (hard disk) 34, and the like. The auxiliary storage device (hard disk) 34 stores map information data 41, building condition data 42, and a design support program 50.

[0021] Here, the map information data 41 is map information data that includes a three-dimensional model and is generated by a map information application such as Google Maps (registered trademark).

[0022] In addition, the building condition data 42 is building condition data including site conditions such as site area and setback distance, building conditions such as building area, total floor area and floor height, and restriction conditions such as floor area ratio, building coverage ratio, height restrictions, slope restrictions and sky exposure ratio.

[0023] As shown in FIG. 3, the design support program 50 is a program that is composed of a building compatibility analysis program 51, a building scale generation program 52, a form and environment analysis program 53, and a design support sheet creation program 54.

[0024] The architectural design support device 100 performs its functions by loading the map information data 41 and architectural condition data 42 stored in the auxiliary storage device (hard disk) 34 into the main storage device (main memory) 33, or by inputting the data using the input device 10 and starting the design support program 50.

[0025] As shown in Figure 4, the design support processing process by the architectural design support device 100 consists of a process 200 for generating a standard-compliant building model, a process 300 for generating a planned building model, a process 400 for evaluating the planned building model, and a process 500 for creating an architectural design support sheet.

[0026] First, the architectural design support device 100 is turned on, the design support program 50 stored in the auxiliary storage device (hard disk) 34 is read into the main storage device (main memory) 33, and started, and then the architectural compatibility analysis program 51 is started.

[0027] The process 200 of generating a code-compliant building model is performed by running the building compliance analysis program 51 .

[0028] When the map information data 41 and building condition data 42 are read or input, the building compatibility analysis program 51 determines site conditions such as site area and setback distance, building conditions such as building area, total floor area and floor height, and restriction conditions such as floor area ratio, building coverage ratio, height restrictions and slope restrictions, and generates a compatible building model for each road boundary line with a scale (volume) that complies with the building condition data 42. This compatible building model is called the standard compatible building model Ms.

[0029] Furthermore, the building conformance analysis program 51 has a sky factor analysis function, and this sky factor analysis function acquires sky factor measurement point data Dp for the standard conformance building model Ms.

[0030] Then, as shown in FIG. 5, the standard-compliant building model Ms and its sky exposure factor measurement point P are displayed on the display 21 in a plan view and a three-dimensional view, together with the site boundary line and road boundary line.

[0031] The sky factor Rs refers to the solid angle projection factor of the sky, (As-Ab) Sky rate Rs(%)=――――――――×100 As It is calculated by: Here, As is the horizontal projection area of ​​the sky map circle, and Ab is the horizontal projection area of ​​the building.

[0032] The process 300 of generating a proposed building model is carried out by running the building volume generation program 52 .

[0033] First, the standard-compliant building model Ms, sky factor measurement point data Dp, and site boundary line generated in the previous step are imported into the building volume generation program 52. In addition, a planned building model at the start is generated and set from the building scale generation conditions (floor height and number of floors of the building model), and this is set as the initial planned building model Mo.

[0034] Next, the building scale (volume) generation program 52 is run, and the sky exposure factors Rs(Ms) and Rs(Mo) are calculated and checked for the standard-compliant building model Ms and the initial planned building model Mo, as shown in Figure 6.

[0035] Then, the sky factor Rs(Ms) of the standard-compliant building model Ms is compared with the sky factor Rs(Mo) of the initial planned building model Mo at each measurement point P, and if there is a measurement point where the sky factor Rs(Mo) of the initial planned building model Mo exceeds the sky factor Rs(Ms) of the standard-compliant building model Ms, the measurement point Pa with the largest difference in sky factor Rs is extracted.

[0036] Next, as shown in Figures 8 and 9, in order to cut the initial planned building model Mo, the elevation angle E relative to the top end and the azimuth angle A relative to the left and right ends are extracted and set using the measurement point Pa as the reference, and are set as the initial elevation angle abutment plane Vo[Eo] and the initial azimuth angle abutment plane Ho[Ao], respectively. Furthermore, for the initial elevation angle contact surface Vo[Eo] and the initial azimuth angle contact surface Ho[Ao], predetermined rotation angles (angle increments) are set to ΔE and ΔA, and the surfaces rotated by those angles are defined as the elevation angle cut surface V1[E1:Eo+ΔE] and the azimuth angle cut surface H1[A1:Ao+ΔA].

[0037] Then, the planned building model obtained by cutting the initial planned building model Mo at the elevation cut plane V1 [E1:Eo+ΔE] and the azimuth cut plane H1 [A1:Ao+ΔA] is defined as the primary planned building model M1.

[0038] The sky factor Rs(M1) is calculated again for the primary planned building model M1 and compared with the sky factor Rs(Ms) of the standard-compliant building model Ms at each measurement point P. If there is a measurement point where the sky factor Rs(M1) of the primary planned building model M1 exceeds the sky factor Rs(Ms) of the standard-compliant building model Ms, the measurement point Pa with the largest difference in sky factor Rs is extracted.

[0039] Then, the primary planned building model M1 is cut at the elevation cut plane V2 [E2:E1+ΔE] and the azimuth cut plane H2 [A2:A1+ΔA], and the planned building model after cutting is defined as the secondary planned building model M2.

[0040] Below, the sky factor Rs(Mn) is calculated for the nth-order planned building model Mn, and compared with the sky factor Rs(Ms) of the standard-compliant building model Ms at each measurement point P. If there is a measurement point where the sky factor Rs(Mn) of the nth-order planned building model Mn exceeds the sky factor Rs(Ms) of the standard-compliant building model Ms, the measurement point Pa with the largest difference in sky factor Rs is extracted, and the nth-order planned building model Mn is cut at the elevation angle cut plane Vn and the azimuth angle cut plane Hn. This operation is automatically repeated.

[0041] On the other hand, if there are no more measurement points whose sky exposure factor Rs(Mn) of the nth-order planned building model Mn exceeds the sky exposure factor Rs(Ms) of the standard-compliant building model Ms, then the nth-order planned building model Mn is extracted.

[0042] Then, as shown in Figure 4, multiple nth-order planned building models Mn are automatically generated and output, in which there are no more measurement points that exceed the sky exposure factor Rs(Ms) of the standard-compliant building model Ms.Since these nth-order planned building models Mn comply with the relaxed conditions based on the sky exposure factor Rs and can become the final planned building model, these nth-order planned building models Mn are specifically referred to as extracted planned building models Mp.

[0043] The proposed building model evaluation process 400 is performed by running the form and environment analysis program 53 .

[0044] First, the extracted planning building model Mp generated in the previous step, the surrounding building model, the environmental analysis data, the cost and energy calculation data, etc. are imported into the form and environmental analysis program 53.

[0045] Next, by running the form and environment analysis program 53, as shown in Figure 10, form analysis results such as the building volume, building area, total floor area, floor height, and floor area of ​​each floor, as well as environmental analysis results such as annual solar radiation, view value, and shadow analysis results are calculated and analyzed for the extracted planned building model Mp.

[0046] As shown in Figures 4 and 11, for each extracted planning building model Mp, the exterior image (perspective) of the extracted planning building model Mp, morphological analysis results such as volume, building area, total floor area, floor height, and area of ​​each floor plan, and environmental analysis results such as annual solar radiation, view value, and shadow analysis results are displayed and output by adding color to the exterior image (perspective).

[0047] Furthermore, the form and environment analysis program 53 has a construction cost and energy consumption estimation function, which can estimate and display the construction cost and energy consumption of the extracted planned building model Mp.

[0048] The architectural design support sheet creation process 500 is executed by running the design support sheet creation program 54.

[0049] When the design support sheet creation program 54 is run, the morphological analysis result data and environmental analysis result data analyzed and extracted by the previous process 400 are read in, and an architectural design support sheet S is created as shown in Figure 12 and displayed on the display 21.

[0050] As shown in FIG. 12, the architectural design support sheet S is divided into an architectural summary section S1, an architectural plan section S2, and an environmental assessment section S3.

[0051] The building summary section S1 displays a three-dimensional exterior image (perspective) of the extracted plan building model Mp and evaluation indicators relating to the floor area, outdoor space, view, environmental friendliness, and cost of the extracted plan building model Mp in the form of a radar chart.

[0052] The building plan section S2 displays a three-dimensional hierarchical image (perspective) of the extracted building plan model Mp and its floor plan, and lists the volume, total floor area, floor height, and area of ​​public spaces of the extracted building plan model Mp. In addition, the plan view of each floor of the extracted planning building model Mp is displayed, and the floor area of ​​each floor is also recorded.

[0053] In the environmental assessment column S3, the annual amount of solar radiation for each floor is displayed by applying transitional colors to the three-dimensional exterior image (perspective) of the extracted planned building model Mp. In addition, the view from each floor is displayed by adding transitional colors to the three-dimensional exterior image (perspective) of the extracted planned building model Mp. Furthermore, the shadow analysis plan of the extracted planning building model Mp displays the shadow analysis results and also lists the value of the building.

[0054] This architectural design support sheet S can be printed and output on paper as appropriate by the printer 22, and can also be stored in the auxiliary storage device (hard disk) 34 as architectural design support data.

[0055] As described above, the architectural design support device 100 of the present invention automatically extracts a large number of candidates for the maximum size (volume) of buildings that can be constructed on the target site in a relatively short time, and automatically selects from these candidates multiple optimal maximum size (volume) of buildings, thereby providing great support in the design and planning of buildings.

[0056] Furthermore, according to the architectural design support device 100 of the present invention, an architectural design support sheet S is created based on various analytical data relating to buildings that can be constructed on the target site, and this architectural design support sheet can be displayed on the display 21 and can also be printed and output on paper as appropriate using the printer 22, making it easier to understand visually.

[0057] As described above, the architectural design support device of the present invention has been specifically described, but it goes without saying that various embodiments are conceivable without departing from the gist of the present invention. [Explanation of symbols]
