An information system is an overall process for generating information necessary for decision-making, collecting and observing information. , it can refer to a system that measures, inputs into a computer, stores, manages, analyzes the stored information, and reflects it in decision-making.

Hereinafter, an automatic building design method according to an embodiment of the present invention will be described.

The technology described below relates to a technique for automatically designing buildings.

First, the building of the present invention may be composed of a single building or a complex building.

Detached buildings refer to buildings such as apartment complexes, single-family buildings (single-family buildings), commercial buildings, and residential-commercial complexes. At this time, the single building may be a building with the same design type. The same design type means that the cross section has the same shape.

The complex consists of a number of single buildings. Complex buildings refer to buildings that constitute apartment complexes, commercial complexes, villa complexes, house town complexes, etc.

The technology described below discloses an automatic architectural design method for automatically designing a complex or single building. Building design includes the process of constructing a single or complex building or determining the layout and number of floors of the buildings.

Hereinafter, it will be explained that the building design device designs the building. A building design device is a device that consistently processes input data and performs the calculations necessary for building design according to a specific model or algorithm. For example, a building design device can be implemented in the form of a PC, a server on a network, a smart device, or a chipset with an embedded design program.

Figure 1 is an example of a system 100 for designing a building. In Figure 1, the building design device shows a computer terminal 130 and a server 140 as examples.

The building design device performs the design of the building according to the project site (site) and restrictions entered by user A.

The spatial information database 110 stores information related to land. Various land-related information stored by the spatial information DB 110 can be collectively named spatial information.

Specifically, the spatial information DB 110 can store information such as map data and land studies. Map data includes data that displays various spatial information, such as spatial location, topography, and place names, as symbols or letters at a certain scale according to survey results. Studying includes intellectual study and comprehensive real estate study.

Cadastral studies include land registers, forest registers, shared land registers, site rights registers, cadastral maps, forest maps, and boundary point coordinate registers, as well as registers and drawings that record the land marks surveyed through cadastral surveys, etc. and the owners of the land. Comprehensive real estate studies include information on land markings and owners, building markings and owners, land use and regulations, and real estate prices. Accordingly, the spatial information DB 110 stores the location of the project site for building design, the use of the project site, regulations of the project site, etc.

The spatial information DB 110 may be a component included in a Geographic Information System (GIS). GIS is an information system for efficient use by converting geographic information into computer data.

The computer terminal 130 receives information about the business site where the building will be constructed from user A. Additionally, the computer terminal 130 receives input from user A on constraints for building design. Restrictions may include building-to-land ratio, floor area ratio, building spacing, number of building floors, site boundary complete value, building type, etc.

The computer terminal 130 can obtain a cadastral map, land use, development restrictions, topographical shape, etc. for the project site and adjacent areas selected by user A in connection with the national GIS. The computer terminal 130 performs optimal building design under constraints entered by the user based on the area and shape of the project site. The specific building design process is described later. The computer terminal 130 can provide the design results to the user as graphic objects and text through a certain interface.

Meanwhile, the computer terminal 130 should be interpreted to mean various electronic devices such as mobile phones, desktops, tablet PCs, and laptops.

The server 140 receives information on the business site where the building will be constructed from user A through the user terminal 50. Additionally, the server 140 receives input from the user terminal 50 on limiting conditions for designing the building. The user terminal 50 may be a device such as a computer device, a smartphone, or the like.

The server 140 can obtain a cadastral map, land use, development restrictions, topographical shape, etc. for the project site and adjacent areas selected by user A in connection with the national GIS. The server 140 performs optimal building design under the constraints entered by the user based on the area and shape of the relevant project site.

The specific building design process is described later. The server 140 may deliver the design result to the user terminal 50. The user terminal 50 may output design results through a web-based program or a dedicated application provided by the server 140.

Figure 2 shows the automatic building design process according to an embodiment of the present invention. Figure 3 shows an example of the automatic building design method implemented as a program according to an embodiment of the present invention.

According to an embodiment of the present invention, the building design device can select the project site (S210).

Referring to FIG. 3, the building design device can output a map including at least one parcel. The map was created in conjunction with GIS and can provide constraints corresponding to specific parcels and cadastral maps.

The building design device can output a UI (User Experience) that allows the user to effectively select a project site among at least one parcel. Specifically, the UI includes a search layer (layer for place name or address search), land information layer (architectural layer, land suitability analysis layer, basic map, topography, cadastral map, individual ordinance local district information, environmental information, forest thematic map information, etc. Includes.) may include.

Through the above layers, the building design device can provide users with various functions such as selecting a cadastral map, business site and drawing, opening site and project files, opening analysis tab, split screen, road view reference, distance/elevation cross-section/visibility analysis, etc. .

Hereinafter, a method of selecting a building as a project site will be described based on FIG. 4 above.

Figure 4 is an example of a process in which a user selects a business destination through a user terminal.

Referring to FIG. 4, the user can select a business site from among at least one parcel included in the map displayed on the screen. At this time, the user's method of selecting a business site may include at least one of address search, paper selection, file selection, and drawing selection.

Specifically, the building design device receives information on the business site where the building will be constructed from the user terminal. For example, the selected business site selection information may be received through at least one of the following methods: searching the user's address, selecting joint paper, selecting a file, or selecting a drawing.

At this time, the user terminal may be a terminal for accessing the server (50 in FIG. 1) or a terminal 130 corresponding to a building design device. As described above, a user can select a business destination by accessing a web browser through a user terminal or running a dedicated application. Users may be required to register and log in to the service before receiving the service.

Figure 4 is an example of an interface and menu that can be used in the process of selecting a business site.

The user terminal can select or receive a business destination in one of three ways. (1) When an address is entered into the interface window, the user terminal can output the corresponding cadastral map and select the parcel selected by the user (clicking the mouse, touching the screen, etc.) as the business site.

Additionally, the user terminal may select multiple parcels as business targets. For example, the user terminal can select a specific key (SHIFT) or a menu (joint writing mode) and then select the parcels to receive input of a plurality of parcels as a business target.

(2) The user terminal can receive input from the user as a business destination with a specific shape. The user terminal can receive input of a site having a certain plan shape through a device such as a mouse. The user terminal can receive a business site of a certain shape on specific parcel(s) of the cadastral map.

(3) The user terminal may receive cadastral map information through a file in a storage device without receiving spatial information from the server. The user terminal can open the selected CAD (DXF) file through the file open menu and then select the original coordinate system to input the business site. Alternatively, the user terminal can open a shared or existing designed project file, view and edit it, and then perform the design process.

Meanwhile, it is also possible for the user's business destination selection information to be obtained through a combination of the disclosed methods.

When a project site is selected through the above process, the building design device can output information on the selected project site.

For example, (1) if the user selects land corresponding to the address of '667-1, Inchang-dong, Guri-si, Gyeonggi-do' through address search, the building design device will search for the lot number, land designation 'Land', and area '28,107 square meters'. ', usage status 'apartment', use area 'type 3 general residential', road 'Jungro angle' shape 'indefinite', land price 'flat', publicly announced land price '2,587,000 won', etc. can be printed out. Through this, users will be able to see at a glance the information that already exists in the business destination they have chosen.

The building design device according to an embodiment of the present invention can receive building design information of the selected project site after selecting the project site (S220).

At this time, the building design information is the limiting conditions to be considered in the architectural design for the selected project site after the selection of the project site is completed (limiting conditions include building-to-land ratio, floor area ratio, building spacing, number of building floors, site boundary complete value, building type, etc.) and business site information may be included. Project site information may include the area of the project site, shape of the project site, slope information of the project site, land use, market price, publicly announced land price, and construction-related restrictions (limitation on number of floors, green belt, etc.) from spatial information DB or GIS. there is.

Meanwhile, some of the plurality of information included in the building design information can be input from the user, and some information may automatically determine the building-to-land ratio or floor area ratio of the selected project site based on land use, etc. for the selected project site. .

For example, referring to S220 in Figure 2, the building design information is for a land area of 254m ² , the use zoning classification is 'Type 2 general residential area', the maximum building-to-land ratio is '60%', the maximum floor area ratio is '250%', and the maximum The number of building floors can be set to '5th floor', the building structure to 'piloti structure', and the solar radiation limit to 'check the adjacent road due north'.

The building design device can perform automatic construction of the building to be constructed at the project site based on the building design information of the project site (S230 to S250). This will be described in detail below.

Figure 5 is an example of a flow chart for the process 500 of designing a building.

The building design device obtains the construction project site and restrictions from the user (S510).

The building design device can receive an address from the user through an input interface menu or input a project site by selecting a specific parcel(s) from a map displayed on the screen.

Additionally, the building design device can receive input from the user through the input interface menu of constraints to be considered in architectural design.

The building design device extracts project site information for the selected project site (S520). The building design device can obtain the area of the project site, shape of the project site, slope information of the project site, land use, market price, publicly announced land price, and construction-related restrictions (limitation on number of floors, green belt, etc.) from spatial information DB or GIS. there is.

Meanwhile, the building design device may automatically determine the building-to-land ratio or floor area ratio of the selected project site based on the land use of the selected project site.

The building design device can automatically design the building based on the selected project site and limiting conditions (S530). The building design algorithm is described later.

Afterwards, the building design device can receive a design edit command for the designed building from the user. Design editing means moving the location of one or more buildings, changing the number of floors, etc. If the design is edited (YES in S540), the building design device updates the design of the building (S550).

If the design has not been edited (NO in S540), the building design device automatically verifies the designed building (S560). If the design has been edited, the updated building is verified (S560). Here, verification may include verification of sunlight access, verification of view rights, verification of human-building spacing, etc.

If verification is successful (YES in S570), the building design process ends. If verification is not successful (NO in S570), the building design device updates the design of the currently designed building (S550). Afterwards, the building design device repeats the process of verifying the updated building again. At this time, the building design device can automatically update the design by adjusting the location or number of floors of the building. Alternatively, in some cases, the building design device may update the building design by receiving information for building update from the user. Below, the specific process of designing the S530 building will be described.

Hereinafter, a building design algorithm according to an embodiment of the present invention will be described. According to an embodiment of the present invention, a building design device can automatically design a single building or a complex building.

First, the design method for a stand-alone building will be explained.

Figure 6 shows a flowchart for explaining the automatic architectural design method for a single-family building according to an embodiment of the present invention.

Referring to FIG. 6, the building design device according to an embodiment of the present invention can set the maximum rectangle that can be constructed at the project site as the building outline (S610).

Specifically, the shape of the land for the project site is not standardized, and the area can be expressed as a parcel composed of complex polygons. Therefore, the main architectural outline of a complex project site can be derived using the maximum rectangle contained within a polygon.

For example, referring to Figure 7, it can be seen that there is an architectural area 710, which is the maximum constructionable area of the project site, and that the architectural area is made up of complex polygons. The building design device can obtain the maximum rectangle (720) that can be implemented in the architectural area (710) as the 'main architectural outline' of the single-building building.

Of course, the area of the rectangle formed by the main building outline may be formed within a range that does not exceed the area according to the building-to-land ratio of the project site.

Meanwhile, in order to find the maximum rectangle according to an embodiment of the present invention, numerous batch learning can be performed, and the greater the amount of batch learning, the more precise the maximum rectangle 720 forming the main building outline can be.

At this time, the construction area 710 may mean an actual buildable site that reflects regulations necessary for construction, such as building limit lines, building lines, wall designation lines, and wall limit lines, in the project site.

Figure 6 will be described again.

The processor according to an embodiment of the present invention can obtain the final building outline by combining it with a new rectangle in the known area (rectangle union & merge) (S620).

For example, referring to FIG. 8, there is an architectural area 820 of the project site 810, and the architectural area may be composed of a complex combination of polygons. The building design device derives the ‘main architectural outline (dotted line, 830)’, which is the maximum rectangle that can be implemented in the architectural area 810, and the ‘main architectural outline (dotted line)’, which is the maximum rectangle that can be implemented in the architectural area 820. , 830)', the empty parcel space (840, 850, etc.) can be derived.

The building design device derives the maximum rectangle for each of the empty lot spaces (840,850) and obtains the 'final building outline (930 in Figure 9)' through a union operation with the existing main building outline (830). You can.

That is, the processor according to an embodiment of the present invention can generate the final building outline by combining the main building outline initially generated in the building area 820 and the outline of the building that combines the rectangles of each empty lot space created thereafter.

S620 according to an embodiment of the present invention is within a range that does not exceed the building-to-land ratio condition, which means the ratio of the building area to the site area of the parcel area corresponding to the project site, or the area, size, and width and height of the empty parcel space. Since any one of these is performed repeatedly within a range that does not deviate from predetermined boundaries, the final building outline can be updated each time the algorithm is repeated.

The final architectural outline derived at this time can become the new main architectural outline when repeated.

In addition, in order to derive the final architectural outline, numerous batch learning can be performed to find the maximum rectangle according to the embodiment of the present invention, and the greater the amount of batch learning, the more precise the maximum rectangle forming the final architectural outline can be. .

Meanwhile, depending on the embodiment, if the building-to-land ratio condition, which means the ratio of the building area to the land area of the lot area corresponding to the project site, is exceeded, or the area or width, height, etc. of the empty lot space exceeds the predetermined boundary, , the iterative process can be terminated.

For example, if the area or width and height of the empty parcel space is less than a preset value, the repetition process can be stopped.

Figure 6 will be described again.

Referring to FIG. 6, the building design device can derive the final architectural outline of the bottom floor through S620 and then derive the final architectural outline for each floor based on the building design information (S630).

Specifically, building design information may include limiting conditions to be considered in architectural design, examples of which include at least one of use area information, building-to-land ratio information, floor area ratio information, building floor information, solar radiation restriction information, building structure information, and building type information. Can contain one piece of information.

First, in an embodiment of the present invention, solar radiation that has a significant impact on the final building outline for each floor will be described. In accordance with the Building Act, solar radiation restrictions apply to the regulation of setting aside a certain distance from the adjacent property line in each due north direction when constructing a building in an exclusive residential area or a general residential area. Parts with a height of 9 m or less are 1.5 m or more from the property boundary line, and 9 m or more from the property boundary line. The excess part refers to the regulation of raising more than 1/2 of the height of each relevant part. In general, since the standard is “3m in height per floor,” the sunlight restriction is not applied up to the 3rd floor.

The building design device can set the final building outline of the floor up to a predetermined value (for example, 3 floors or 9 m or less) based on the final building outline derived from S620.

In addition, if the information included in the building design information corresponds to a general residential area or an exclusive residential area and the number of floors of the building exceeds a predetermined value (for example, 3 floors or 9m), the building design device Based on the restriction information, the final building outline can be changed so that it is more than 1/2 of the height of each part of the building in question from the adjacent site boundary line, and the changed final building outline can be set as the final building outline for the corresponding number of floors.

For example, referring to FIG. 9, the final building outline 930 derived in S620 may exist on the construction site 920 included in the project site 910.

The building design device sets the final building outline of the predetermined number of floors to be the same as '930' based on the final building outline (930), and for floors exceeding the predetermined floor, the height of each part of the building in question is from the adjacent site boundary line. The final building outline can be changed so that it is spaced apart by more than one-half of , and the changed final building outline 940 can be set as the final building outline of the corresponding floor.

The above process can be repeated within the range that does not exceed the floor area ratio of the building or satisfies the minimum building area, and by repeating the above process, the final building outline (930 to 960) for each floor is derived based on the building design information. can do.

Figure 6 will be described again.

After deriving the final building outline for each floor, the building design device can derive the building form by refining the final building exterior (S640).

Figure 10 shows a simulation process for deriving the shape of a building through trimming the exterior of the final building according to an embodiment of the present invention.

Referring to (a) of FIG. 10, the first building 1010 corresponds to an example of deriving the final building outline for each floor generated according to building design information.

Specifically, the building design device can generate a building made up of simple squares as an intermediate product (1010) by merging the existing maximum rectangle and the rectangles for each empty parcel space.

More specifically, the final building outline is created by combining the initially generated main building outline and the outline of the building that combines each rectangle of the empty lot space created thereafter, and the final building outline is three-dimensionalized for each floor to create the first building (1010). can be created.

The first building 1010 may refer to a building before finishing the exterior of the final building.

Referring to (b) of FIG. 10, the second building 1020 is a diagram shown to explain the process before the final building 930 of FIG. 10 (c) is obtained.

According to an embodiment of the present invention, optimization of the adjacent distance and angle with the vertex of the first building 1010 and trimming of the building may be performed based on the outer angle and inner angle (convex/concave).

Specifically, we will explain how to refine the exterior of a building. Comparing (a) and (b) of Figures 10, the exterior of the building on a specific floor is created by combining the outlines of the building by combining each rectangle, and the exterior of the building on the specific floor has a plurality of vertices. exists.

According to an embodiment of the present invention, the processor refines the exterior of the building according to the distance between adjacent vertices among the plurality of vertices present on the exterior of the building of the specific floor, the angle between the plurality of vertices, and the degree of outer and inner angles (convex/concave). It can be done.

For example, as shown in '1011' and '1021', when the distance between adjacent vertices (vertices) is less than a predetermined value, or when the angle between a plurality of vertices is less than a predetermined value, or the outer angle formed by a plurality of vertices Based on the degree of convexity/concaveness of the building exterior according to the relationship between and interior angles, a plurality of vertices can be deleted within the error range of the building area of the specific floor and a single flat building exterior can be created.

At this time, 'within the error range of the building area on a specific floor' may be the same as the building area on a specific floor, or may be a value with an error equal to a predetermined boundary.

The processor according to the embodiment of the present invention may repeatedly perform the above process for each floor to obtain the final building form 1030 on which the exterior of the building has been trimmed.

Through the above process, the building design device can create a stand-alone building and perform design compilation and verification for the generated building.

Below, the editing and verification process when a stand-alone building is created is explained.

The building design device can edit the designed building and verify the designed building (S540 to S570).

First, the verification process for stand-alone buildings will be explained.

This corresponds to S240 in Figure 2 and may correspond to verification of site area, human space spacing (in case of complex design model), 2.5/3D shadow, bird's eye view, etc.

Specifically, the building design device can proceed with architectural design by applying solar radiation line restrictions and building-to-land ratio/floor area ratio to ensure that the designed building is within the scope of regulations of related organizations.

In general, the restriction of diagonal lines for sunlight may refer to regulations set by the Building Act to set a certain distance or more from the adjacent property line in each due north direction when constructing a building in an exclusive or general residential area. The part under 9m in height must be set aside by 1.5m from the property boundary line, and the part over 9m in height must be set aside by more than 1/2 of the height of the part. (Reflected based on conditions such as the width of the road due north and whether or not it is adjacent).

The building design device can use the building verification model to perform the following solar access verification and building-to-land ratio and floor area ratio verification.

- Check whether the land designation of the adjacent parcel due north is "road" (land characteristics include the width of the adjacent road, but it is only used as ledger information for the adjacent road)

- Negative buffering is applied by applying the building-to-land ratio, matching the southern building line, and recalculating the solar radiation line compared to the distance of the setback line.

- Apply building-to-land ratio and maximum number of floors based on land characteristics information or use area of the target site.

- When applying the building-to-land ratio and solar irradiation on the 4th floor or higher, areas under 7 pyeong are excluded. (When applying the building-to-land ratio, it is applied to match the southern building line)

- Application of piloti structure and roof/wall materials.

- Shadow (based on solar radiation regulations, not the sun's position at a specific date and time)

- Optional functions such as compass, automatic rotation, number of building floors, and wall/roof material selection are provided.

Meanwhile, according to an embodiment of the present invention, a user may request editing of a building design that reflects the user's preference for the final building created according to the building design information. The building design device may receive a final building design edit request generated from the user and regenerate (update) the building based on the received building design edit information (S540, S550).

Specifically, the building design device can provide a customized architectural design according to change information in building design information based on user input for a building designed based on a single-building building design model.

For example, users can change the building shape included in the building design information according to their preference and design a customized building according to the plate type or optimal shape.

<How to design complex buildings>

Figure 11 is an example of the automatic design process (S530) of a complex building.

The building design device performs directional analysis on the selected project site (S1110). The building design device can check the direction of the project site and adjust it so that the project site is south-facing and horizontal, assuming the building is placed.

This is to arrange the building design device so that the lighting direction of the building to be placed is basically towards the south. Furthermore, the building design device can determine the direction in which as many buildings as possible can be placed depending on the plan shape of the project site. Details about directional analysis will be described later.

The building design device initially arranges as many buildings as possible in the target business site according to a certain packing algorithm (S1120).

The building design device places virtual building objects on a virtual site or area corresponding to the target business site. The building design device can adjust the arrangement again according to the building design type (S1130).

Afterwards, the building design device can adjust the location and/or number of floors of the building according to the type of site boundary buffer zone, site area verification, building spacing, and building-to-land ratio/floor area ratio (S1140). The detailed building arrangement process will be described later.

The building design device can receive commands from the user, such as changing the design type, additionally arranging buildings of a different design type, adjusting the location of a specific building, adjusting the number of floors of a specific building, etc.

In this case, the building design device can readjust the arrangement position again based on the updated information among the design type of the changed building, the additionally placed building, the location of the changed building, and the number of floors of the changed building (S1150).

The building design device can adjust the building location and/or number of floors according to the type of site boundary buffer zone, site area verification, building spacing, and building-to-land ratio/floor area ratio.

The business site direction analysis (S1110) will be further explained. A building design device can determine the direction of a project site in several ways. Here, directionality refers to the standard direction in which buildings are placed at the project site.

(1) Since south-facing buildings are traditionally preferred in Korea, the building design device can determine the geographical direction at the project site and ensure that the buildings are basically arranged to face south.

(2) Furthermore, the building design device can determine the direction in which the most buildings can be placed based on the plan shape of the project site.

The building design device can determine the direction of the project site based on the minimum boundary rectangle (MBR) for the project site. MBR can be determined by an algorithm such as Axis Aligned Bounding Box (AABB) or Oriented Minimum Bounding Box (OMBB). In some cases, the building design device may determine the MBR using AABB and then determine the optimal area again using OMBB.

(3) Of course, the building design device can also arrange the building based on the direction input by the user.

Figure 12 is an example of the process of determining the direction of the project site.

Figure 12 is an example of determining the MBR of a project site with OMBB. The building design device can determine the square with the smallest area as the MBR by rotating at a certain angle (0 to 360 degrees) based on the center of gravity of the project site.

Figure 13 is an example of building arrangement according to the decision on the direction of the project site.

Figure 13(A) is an example of arranging a building while confirming the north, south, east, west, and west directions of the project site and ensuring that the main skylight of the building is oriented toward the south. Figure 13(B) is an example of determining the MBR (rectangular dotted box) of the project site and arranging the buildings in a direction parallel to the long side of the rectangle. As shown in Figure 13(B), if buildings are placed based on the direction of the MBR of the project site, there is a high possibility that more buildings will be placed at the project site.

The initial building arrangement process (S1120) is further explained. The building design device performs the initial layout of the building based on the minimum boundary area (MBR). Here, MBR refers to a single building.

Figure 14 is an example of setting the minimum boundary area for automatic placement of buildings. Figure 14 shows the shape of MBR according to design type. Figure 14 shows examples of design types such as plate type (straight type), L type, Y type, and T type. Of course, the plan shape of the building may be different from that of Figure 14.

Depending on the building design type, the building design device sets a bounding box based on the plane of the building based on the diagonal ratio to the direction of the skylight. Afterwards, when the building design device determines the building spacing based on the number of floors (height) of the building, it determines the MBR including the building spacing. Artificial spacing refers to the distance from adjacent buildings based on the direction of the skylight. In other words, the building design device sets the MBR for one building, including the distance between adjacent buildings according to the design type.

Figure 15 is an example of the packing-based initial building arrangement process.

Figure 15 shows a plate-shaped building as an example. The MBR of the building in question is indicated by a dotted box. The business site can have various shapes. In Figure 15, the project site is indicated by a thick solid line.

The building design device is arranged to pack as many MBRs as possible at the target project site. The packing algorithm boils down to the problem of filling boxes in a certain space, and various methodologies exist. For example, there are packing algorithms such as Shelf and Maxtrects. The building design device can fill in as many MBRs as possible, expressed as boxes, on the project site by using a specific algorithm among various algorithms. Figure 15(A) is an example of packing as many MBRs as possible at the project site. Afterwards, the building design device moves each row and column in which the MBRs are arranged in a certain direction and adjusts the placement of as many MBRs as possible. At this time, the building design device can place as many buildings as possible on the project site by controlling the actual buildings to be located on the project site, rather than the square corresponding to the MBR.

Figure 15(B) shows the position of specific rows and columns in Figure 15(A), adjusted so that as many buildings as possible are placed on the project site. Buildings indicated by diagonal lines in Figure 15(B) were additionally placed at the project site.

In the case of buildings such as apartments, multiple households can generally be placed on the same floor of one building. Accordingly, a building may have a plan shape with only some units depending on the design type. For example, a plate-shaped building can be constructed as a building with half the size in the longitudinal direction (a 1/2 building). If such construction is possible, the building design device can arrange the building so that there is as little remaining area as possible by placing 1/2 the building in the remaining area when packing the initial MBR.

The relocation process (S1130) based on the design type is further explained. Once MBR placement according to the packing algorithm is completed, the building design device places only the building model according to the design type, not the MBR, to the project site. Considering several conditions, the building design device adjusts the location and/or number of floors of the building.

The building design device can move the entire complex of buildings so that the buildings are as close as possible to the southern building limit line (buffer zone tangent) at the project site based on the actual shape of the building.

First, the building design device can basically adjust the design of the complex based on the building-to-land ratio and floor area ratio.

If the currently placed buildings do not satisfy the allowable building-to-land ratio, the building design device can delete some of the currently placed buildings according to the allowable building-to-land ratio. When deleting a specific building to satisfy the building-to-land ratio conditions, the building design device can delete buildings starting from those closest to the northern building line. Additionally, the building design device may first delete buildings with a small area or buildings with a low number of stories (for example, 5 stories or less). If the building-to-land ratio condition is not satisfied even after deleting the building(s) close to the northern building line, the building design device can be adjusted to satisfy the building-to-land ratio by deleting buildings close to the east, west, or south building lines.

If the currently placed complex does not satisfy the allowable floor area ratio, the building design device can reduce the number of floors of some of the buildings among the plurality of buildings to satisfy the allowable floor area ratio. At this time, the building design device can start from the highest floor of a specific building and reduce the floors one by one. If there is a building lower than the standard height (e.g., 5th floor), the building design device may delete the building itself.

Afterwards, the building design device can adjust the arrangement of individual buildings to ensure sunlight (H/2) in the north direction and view lines (H/2) from east/west/south skylights. Here, H means the height of the building. This is to reflect the sunlight and view rights of individual buildings.

Figure 16 is an example of adjusting the location after placing a building of the corresponding design type.

Figure 16 is an example of adjusting the arrangement position of a plate-shaped building to reflect the northern solar irradiance and the east, west, and south light lines.

The building design device can optimize the location of the building by further performing processes such as site area verification, building spacing verification, and sunlight shading verification.

Figure 17 is an example of the land area verification process.

The building design device can verify the solar rays from the north and the view lines from skylights facing east, west, and south. The survey line on the north side of the building has a large aspect to secure sunlight. Meanwhile, the east-west/south-facing view lines of the building are important for privacy protection. Figure 17(A) is an example of a case where the distance between buildings is 1H and there is sufficient green space or public facilities around the construction line. Looking at Figure 17(A), this is a case where green space or public facilities are located around the complex building, so that the northern sunlight line or the view line toward the skylight is secured. Figure 17(B) shows a case where the distance between buildings is 1H and there are no roads, green spaces, or public facilities around the construction line. Looking at Figure 17(B), although the northern solar radiation line (H/2) was secured, the view line (1/2H) of the skylight of the building located to the south was not secured.

In this case, the building design device can display specific buildings that exceed the constraints in a different color. Furthermore, the building design device can adjust the arrangement position of the building or other buildings so that the skylight view line of the building is secured. In some cases, the building design device may adjust the arrangement angle of the building in question so that the skylight view line of the building is secured. Additionally, the building design device may adjust the number of floors of the building to ensure a skylight view line of the building.

Figure 18 is an example of the human motion gap verification process.

Figure 18(A) shows a case where there is no problem with the gap between the building skylight and the adjacent building. Figure 18(B) shows a case where there is a problem with the spacing between buildings. The building design device can display buildings with building spacings that are closer than specified in a different color. Furthermore, the building design device can adjust the arrangement position of the building or other buildings to ensure the space between the buildings. In some cases, the building design device may adjust the arrangement angle of the building in question to ensure the space between the buildings in question. Additionally, the building design device may adjust the number of floors of the building to ensure space between buildings.

Figure 19 is an example of the solar shading verification process.

The building design device can perform sunlight analysis for each building in the complex that is placed. Sunlight shading verification verifies whether the building in question has a certain amount of sunlight. The building design device can evaluate whether sunlight is secured in the building based on specific standards for sunlight. For example, a building design device can evaluate whether continuous sunlight is secured for more than 2 hours during the winter solstice, the shortest day of the year, for a specific building. For this purpose, the building design device can use information such as solar elevation angle, solar path, solar position (elevation/azimuth), sunrise azimuth, and sunset azimuth at the time of the winter solstice at the relevant project site. Building design devices can check solar access over time through simulation programs. Furthermore, if there are structures such as other terrain or buildings around the project site, the building design device can verify the right to sunlight of a specific building within the project site by considering the structure.

The building design device can adjust the placement position of the building or other buildings to satisfy the sunlight conditions of the building. In some cases, the building design device may adjust the placement angle of the building to satisfy the sunlight conditions of the building. In addition, the building design device may adjust the number of floors of the building to satisfy the sunlight conditions of the building.

Figure 20 is an example of adjusting the location after placing a complex type building.

Buildings of different design types can be placed in one complex. The building design device can receive additional building layout input from the user. Figure 20(A) is an example of a complex arrangement of different types of buildings. In this case, when the layout of the complex type building is completed, the building design device can perform the above-described site area verification, building spacing verification, and sunlight access verification based on the plan shape of the currently placed building. Meanwhile, the building design device can combine 1/2 plate-shaped buildings into one plate-shaped building and convert the plate-shaped building into a shape such as L-type or T-type.

In the process of creating a complex building according to an embodiment of the present invention, the building design device can edit the designed building and verify the designed building (S540 to S570).

The above process can be performed in the same way as the editing and verification process for a single building, and it is also possible to repeat the processes of FIGS. 17 to 20.

Figure 21 is an example of a screen on which the design and arrangement of a single building has been completed.

In Figure 21, the left menu displays design conditions for project site and stand-alone building design. The bottom of the left menu can display information about the final designed single-family building (building-to-land ratio, floor area ratio, total floor area, number of buildings, number of households, etc.). The right side of the architectural information in Figure 21 displays the plan shape of the designed project site. The right side of the plan of Figure 21 displays a stand-alone building designed with three-dimensional graphics.

Referring to FIG. 21, a building 2110 based on the land shape, the user can change the building shape included in the building design information according to preference, and the building design device selects a plate type 2120 or an optimal shape (2120) based on the changed building shape. 2130) can be created.

Furthermore, the building design device can display complex buildings designed together with surrounding buildings or structures in three-dimensional graphics.

Figure 22 is an example of a screen where the building design and layout has been completed.

In Figure 22, the left menu displays design conditions for designing the project site and complex buildings. The bottom of the left menu can display information about the final designed complex (building-to-land ratio, floor area ratio, total floor area, number of buildings, number of households, etc.). The upper right corner of Figure 22 displays the plan shape of the designed project site. The lower right corner of Figure 22 displays a complex of buildings designed with three-dimensional graphics. Furthermore, the building design device can display complex buildings designed together with surrounding buildings or structures in three-dimensional graphics.

According to an embodiment of the present invention, the building design device may store information about the building created in FIG. 21 or FIG. 22 in the memory. At this time, the extension of the saved file may include '.build', and when the user requests storage, the building design device can create a '.build' file. The generated file can be provided to the user.

Users can process and transmit files provided from building design devices, and the transmitted files can be loaded on platforms provided by other building design devices through the 'Open File' menu at the top of Figure 3.

Through this, users of the building design device will be able to easily review the planning design and share content for the project site.

Meanwhile, according to an embodiment of the present invention, the building design device can determine the type of design model (single/complex) of the building to be built on the selected lot based on the area of the selected project site.

As described above, the design method for a single building or a complex building was explained.

Meanwhile, when automatically designing a building (S530), the building design device can decide whether to design a single building or a complex building based on the area of the project site. This will be explained in Figure 23.

Referring to FIG. 23, the building design device can perform stand-alone (villas/building, etc.) building design (S2311) when the project site area is less than a predetermined first value (e.g., 2,000 m2) (S2310). ).

In addition, in the process of setting the design information for the building at the project site, the building design device sets the building design model of the building design department 130 to 'complex ( apartments/villas/building complexes, etc.) can be designed.

Alternatively, if the area of the project site falls within a certain boundary (for example, 500 ~ 4,000㎡), the building design model can be set to be interchangeable between 'single building design mode' and 'single building design mode' according to the user's preference. You can.

Specifically, when the building design device sets the building design model of the project site to 'single building (villa/building, etc.) design mode', and receives user input corresponding to the apartment type option among the user's 'building type' options, The building design model of the project site can be changed to ‘complex design mode’ (S2321).

Similarly, when the building design model of the project site is set to 'complex design mode' and a user input corresponding to the optimal land shape option among the user's 'building type' options is received, the building design device models the building design of the project site. can be changed to ‘single building design mode’ (S2331).

In other words, the building design device can determine the building design model constructed on the relevant lot based on the area of the selected project site, and the building design model can be determined by building design information (user input) if the area of the project site is within a certain boundary. You can change the type of building to be built based on multiple options (including multiple options).

On the other hand, if an appropriate complex building is not created in the complex design mode based on the area, shape, slope information, land use, market price, and restrictive conditions of the project site, the building design device determines that no building has been created and operates alone. It is also possible to change to design mode (S2340).

When the architectural design model is determined through the above process, the building design device can perform a building design corresponding to the building type selected at the project site (S530).

Below, we briefly describe the balance of payments analysis to analyze real estate-related business feasibility.

Referring to FIG. 2, the building design device according to an embodiment of the present invention can provide simple financial analysis results for surrounding market prices and real estate business information using the created virtual building (S231).

Balance analysis may mean analyzing at least one of the expected land purchase price, expected construction cost, and expected sale price based on construction cost/sale price, average land purchase price, average construction cost, and average sale price.

Through this, we will be able to provide an automatic architectural design system that applies big data and artificial intelligence solutions as an initial decision-making support system for housing construction projects with one-stop automated design from location analysis to business feasibility analysis.
