Various techniques have been known related to visually implementing a real estate object including a building in a 3D coordinate space of a virtual reality environment based on geographic information, and a detailed description thereof will be omitted. For example, commercial services such as ZIQWORLD, EARTH2, and METAVERSE2 are known.

The indoor space information of a building can be generated by extracting the shape and simple property information of an indoor structure among BIM (Building Information Modeling, 3D Design Information) information for designing a building. Korean Patent Registration 10-1876499 (July 3, 2018), Republic of Korea Patent Registration 10-2125683 (June 17, 2020) filed by the present applicant in relation to a technology for visualizing a three-dimensional virtual building based on BIM information 1) and the like have been known, and a detailed description thereof will be omitted.

The virtual reality server 100 of the present embodiment interworks with the real estate information server 400 that manages information about real estate including buildings, and receives real estate information in real time.

For example, information about real estate includes address information about real estate sales, property structure information (type of building, number of floors, area), price information (sale price and rental amount entered by the seller), published price information, actual transaction price information, etc. includes

For example, as a commercial service providing information on real estate, Naver Real Estate, Jikbang, Cafe, Real Estate Bank, Real Estate 114, and Maekyung Real Estate can be exemplified. These commercial services provide information on real estate for each region based on map information. The real estate information server 400 of this embodiment may be understood as a server providing such a service.

The building information of this embodiment includes information on the size, location, direction, etc. of a building based on geographic information, indoor space information based on BIM information, and information on real estate provided by the real estate information server 400 (related to real estate for sale). address information, property structure information, price information, published price information, actual transaction price information, etc.).

Since the building information of this embodiment includes geographic information and BIM information, visual implementation of each building object in a virtual reality environment is possible, and real estate is assigned to each building object in a virtual reality environment based on the address of each building. Data is managed by matching related information. Therefore, when a specific building object is selected in a virtual reality environment, the user interface provides real estate sale-related information, property structure information, price information, official price information, actual transaction price information, etc. for the building on the screen of the user client 200. The user can check through (UI).

For example, the building of this embodiment may be a commercial building capable of recovering investment through rental income.

Preferably, the virtual reality of this embodiment may be based on digital twin technology in which terrain and features of the real world are implemented in a virtual world in a computer.

The virtual reality server 100 of this embodiment interworks with the user client 200 and the manager client 300 through the network 1 .

The user client 200 is a client of a user who accesses the virtual reality server 100 through a network 1 such as the Internet or an intranet and uses various virtual reality-based services (eg, real estate investment simulation, etc.). The user may be a user registered in the virtual reality server 100 through a normal user member registration process, but is not limited thereto. In the terrain and building environment constituting the virtual reality, the simulation target building can visually implement various virtual building states based on various option inputs by a user's manipulation input or a preset algorithm.

The manager client 300 is a manager client that accesses the virtual reality server 100 through a network 1 such as the Internet or an intranet and executes data management and user registration management to implement a virtual reality environment.

From a functional point of view, the virtual reality server 100 of this embodiment implements virtual reality in a three-dimensional coordinate space based on geographic information and building information and visually provides it on the screen of the user client 200 or the manager client 300 A virtual reality implementation module 102, an investment information processing module 104 for inputting search information and option information for investment simulation based on the real estate investment simulation method of the present embodiment, and executing information search and result providing processing accordingly, An investment simulation implementation module 106 that provides an investment simulation mode based on input and searched information and provides simulation results (virtual building realization, investment amount calculation), member registration and various member management modes, virtual reality such as manager mode It includes an operation module 108 that provides overall management functions of the server 100 .

For example, some of the functional modules may be distributed and implemented in the form of a separate server that works with the virtual reality server 100 over a network.

In addition, the virtual reality server 100 of this embodiment includes a geographic information DB 112 for storing and updating and managing geographic information for realizing virtual reality, and a building information DB for storing and updating and managing building information for realizing virtual reality. (114), an investment simulation information DB 116 for storing and updating information on investment simulation results set based on the real estate investment simulation method of this embodiment, and a user information DB 118 for storing and updating user information. include

For example, the geographic information DB 112 and/or the building information DB 114 provides all or part of information from a separate geographic information providing server (eg, the National Geographic Information Institute server) interworking with the virtual reality server 100 over a network. may receive

Among the building information, the indoor space information may extract the shape of the indoor structure and simple attribute information from BIM (Building Information Modeling, 3D Design Information) information for designing the building, and input and manage them into the building information DB 114.

Among building information, address information on real estate sales, property structure information (building type, number of floors, area), price information (sale price, jeonse price, monthly rent amount entered by the seller), official price information, actual transaction price information, etc. are real estate It may be provided from the information server 400 .

Referring to FIG. 3, from a hardware point of view, the virtual reality server 100 of this embodiment includes a memory 2 for storing one or more commands and a processor 4 for executing the one or more commands stored in the memory 2. It is a computing device on which a computer program stored in a medium is executed to execute a real estate investment simulation method in a virtual reality environment. The virtual reality server 100 of this embodiment may include a data input/output interface 6, a communication interface 8, a data display unit 3, and a data storage unit 5.

4 to 7 are schematic diagrams for explaining a real estate investment simulation method in a virtual reality environment according to an embodiment of the present invention.

In step 1), the virtual reality server 100 searches for a building that matches the basic investment amount condition input from the user client 200 .

The basic investment amount is the basic amount that the user is considering investing in real estate, and is less than or equal to the total investment amount described later.

For example, if the user has a possible holding amount for real estate investment of 2 billion won and intends to remodel the purchased building, the user may input a basic investment amount of about 1.5 billion won. 500 million won, which corresponds to the difference, will be used for future remodeling costs and will be reserved as surplus funds.

For example, if the user has a possible holding amount for real estate investment of 2 billion won and intends to rebuild the purchased building, he or she may input a basic investment amount of about 1.2 billion won. 800 million won, which corresponds to the difference, is reserved as a spare fund considering that it will be used for future reconstruction costs.

For example, if the user has 2 billion won in real estate investment and does not intend to remodel or reconstruct the purchased building, he or she may input 2 billion won as the basic investment amount.

The search may be performed under a single price condition of the input basic investment amount, or may be performed by generating a range value according to a preset condition.

For example, the amount range (1.5 billion-45 million won ~ 15 KRW 100 million + 45 million won) is calculated, and a building whose purchase cost falls within the range of the calculated amount may be searched. In this case, the input basic investment amount is '1.5 billion won', and the basic investment amount condition for search is '1.5 billion - 45 million won - 1.5 billion won + 45 million won'.

In the case of searching under the single price condition of the input basic investment amount, the input basic investment amount is '1.5 billion', and the basic investment amount condition for the search is also '1.5 billion'.

The basic investment amount is assumed based on the building purchase cost for real estate investment. For example, it may be set to include only the current market price of the building, or may be set to an amount including the current market price of the building and taxes and public charges.

In step 1), the searched buildings are visually displayed on the screen of the user client 200 in the virtual reality environment so that the searched buildings can be compared with each other.

For example, the provision of the display may be performed by visually displaying searched buildings and attribute information on the corresponding buildings on the screen of the user client 200 simultaneously or sequentially.

For example, providing a visual display of a building object in a virtual reality environment may be implemented based on a polygon mesh based on geographic information and building information, and since many technologies for this are known, detailed descriptions are given below. omit

In step 2), the virtual reality server 100 receives, from the user client 200, building information about a building selected as an investment review target and option information for investment simulation based on the search result.

For example, as a result of the above search, if three buildings with current market prices in the range of '1.5 billion won - 45 million won ~ 1.5 billion won + 45 million won' are searched, one or more buildings among the three buildings are to be considered for investment review. You can choose.

The virtual reality server 100 provides information about the size, location, direction, etc. of the building based on geographic information, indoor space information based on BIM information, and real estate information provided by the real estate information server 400 for the selected building. It is possible to provide building information including address information, property structure information, price information, publicly announced price information, actual transaction price information, and the like for real estate sales based on . For example, information on the size, location, direction, etc. of a building based on geographic information and indoor space information based on BIM information can be visually displayed and provided as a rendered building object in a 3D virtual reality environment. Information may be displayed and provided in the form of property information of a building through a user interface screen connected to the corresponding building.

The option information may be input through a user interface screen for inputting option information.

The option information is information for selecting one of a first option for investing in the selected building as it is in its original state, a second option for investing by remodeling the selected building, and a third option for investing by reconstructing the selected building.

In step 3), the virtual reality server 100 provides an investment simulation mode based on the input building information and option information, and calculates the total investment amount based on the investment simulation result of the investment simulation mode.

The investment simulation mode includes a remodeling simulation mode and a reconstruction simulation mode.

The remodeling simulation mode is provided when the second option is selected, and an additional investment amount (additional cost for remodeling) is calculated based on remodeling simulation information input in the remodeling simulation mode. This will be described later in detail.

The reconstruction simulation mode is provided when the third option is selected, and an additional investment amount (additional cost for reconstruction) is calculated based on reconstruction simulation information input in the reconstruction simulation mode. This will be described later in detail.

In the case of selecting the first option, since no additional amount is required other than the basic investment amount, the investment simulation mode is not provided and step 2) ends. Since the buildings searched in step 1) are visually displayed so that they can be compared with each other, the user can make an investment decision based on this.

In step 4), the virtual reality server 100 additionally searches for a building that matches the calculated total investment amount condition.

Additional search for a building that matches the calculated total investment amount condition is the result of remodeling or reconstruction simulation by spending an additional investment amount on the building searched under the condition of the basic investment amount, and the sum of the basic investment amount and the additional investment amount. This is to compare which building has more investment merit by comparing other buildings (other buildings that have not been remodeled or reconstructed) searched for according to the investment amount condition in a virtual reality environment.

For example, the user sets the basic investment amount of 1.5 billion won as a search condition and the additional investment for remodeling as 500 million won for a building simulated for remodeling, and a building searched for with a total investment of 2 billion won as a search condition (remodeling or Other buildings that have not been reconstructed) can be compared to compare which building has more investment merit.

The search in step 4) may be performed under a single price condition of the calculated total investment amount, or may be performed by generating a range value according to a preset condition.

For example, based on the calculated total investment amount (e.g., 2 billion won), the amount reduction rate (-2%) is reflected according to the pre-set conditions to calculate the amount range (2 billion won - 40 million won to 2 billion won), and purchase the building A building whose cost falls within the range of the calculated amount may be additionally searched for. In this case, the calculated total investment amount is '2 billion won', and the total investment amount condition for search is '2 billion won - 40 million won - 2 billion won'.

In the case of searching under the single price condition of the calculated total investment amount, the calculated total investment amount is '2 billion won', and the total investment amount condition for search is also '2 billion won'.

Since the total investment amount can be viewed as the maximum amount available to the user, the amount increase rate is not applied.

In step 5), the virtual reality server 100 visually displays on the screen of the user client 200 in a virtual reality environment so that the selected building reflected the investment simulation result and the additionally searched building can be compared.

Through this configuration, in the real estate investment simulation method of the present embodiment, the user who is considering real estate investment searches for a building that matches the investment amount in consideration of the amount he or she can invest in a virtual reality environment implemented identically to real estate information, You can compare and review the feasibility of investment through simulations according to various options of investment in the searched original building, investment in remodeling, or investment in reconstruction.

Typically, remodeling or reconstruction can increase the return on investment because it increases the value of the building or land. However, since remodeling or reconstruction requires additional cost and time, and difficulties in architectural design/construction management, it is difficult to easily determine whether or not to proceed. In view of this, the real estate investment simulation method of this embodiment is based on the same total investment amount, based on various options of original building investment, remodeling investment, and reconstruction investment. It is possible to compare simulations of virtual reality environments to help with this decision. is configured to give

In the case of mutual comparison of buildings, information on the size, location, direction, etc. of buildings based on geographic information, indoor space information based on BIM information, and real estate sales based on real estate information provided by the real estate information server 400 Building information including address information, property structure information, price information, official price information, actual transaction price information, and the like can be compared as a whole.

In addition, when comparing buildings with each other, information on the size, location, direction, etc. of buildings based on geographic information and indoor space information based on BIM information are used to visually implement each building object in a virtual reality environment. provides

In addition, information on real estate for each building object matched and managed based on the address of each building is provided. Information on real estate includes information related to real estate sales for each building, property structure information, price information, published price information, actual transaction price information, etc., and provides a user interface (UI) provided on the screen of the user client 200. provided to the user through

Meanwhile, in more detail, when the second option is input in step 2), step 3) may be executed as follows.

In step 31), the virtual reality server 100 provides the user client 200 with a remodeling simulation mode for the selected building. The remodeling simulation mode is provided in the form of a user interface (UI) capable of inputting remodeling simulation information.

In step 32), the virtual reality server 100 receives remodeling simulation information for the selected building from the user client 200 in the remodeling simulation mode.

The remodeling simulation information includes building interior remodeling information and building exterior remodeling information.

For example, the building interior remodeling information is input to simulate the type of interior materials, the price of the interior materials, and the like for constructing the interior environment of the building. Interior materials may include conventional interior materials such as ceiling materials, wallpaper, flooring materials, doors, lighting fixtures, and the like.

For example, the building exterior remodeling information is input to simulate the type of exterior materials, the price of the exterior materials, and the like for configuring the exterior environment of the building. Materials for configuring the exterior environment may include general exterior materials such as building exterior panels, exterior wall glass, exterior access doors, exterior lighting fixtures, and exterior painting.

In step 33), the virtual reality server 100 provides the user client 200 with a simulation result in which the selected building is remodeled in a virtual reality environment based on the inputted remodeling simulation information.

For example, the remodeling simulation result is inputted in a state in which a building object is visually implemented in a virtual reality environment using information on the size, location, direction, etc. of a building based on geographic information and indoor space information based on BIM information. It may be executed in a way of visually simulating and realizing a state in which the interior materials and exterior materials included in the remodeling simulation information are virtually arranged or installed based on preset simulation rules.

The simulation rule is used to determine the required quantity and arrangement of interior and exterior materials according to building structural conditions, such as n flooring materials per 1 m2 of floor area and n lighting fixtures per 1 m2 of floor area. It can be understood as a rule for Simulation rules may be set by the manager client 300 .

Also, the visual implementation form of the building may be determined based on the simulation rules.

In step 34), the virtual reality server 100 calculates an additional investment amount based on the remodeling simulation information.

For example, the additional investment amount is calculated by adding the cost required for interior remodeling of the building and the cost required for exterior remodeling of the building.

The cost required for building interior remodeling is calculated based on the type of interior materials, the price of interior materials, and the quantity or area of interior materials required for the simulation implementation.

The cost required for building exterior remodeling is calculated based on the type of exterior materials, the price of exterior materials, and the quantity or area of exterior materials required for the simulation implementation.

The price of interior materials may be entered into the virtual reality server 100 and managed in the form of a price per quantity (eg, lighting fixtures, doors) or a price per area (eg, ceiling materials, wallpaper, and flooring materials). As a modified example, the price per area may be calculated according to a rule set in advance in consideration of the size and area of a building even in the case of a door and a lighting fixture. Table 1 below illustrates these prices.

ceiling material
(per ㎡) wallpaper
(per ㎡) flooring
(per ㎡) lighting fixtures
(per dog) door
(per dog) Class A 30000 ... ... ... ... Class B 25000 ... ... ... ... Class C 20000 ... ... ... ...

The price of exterior materials is entered into the virtual reality server 100 and managed in the form of a price per quantity (eg, exterior doors and external lighting fixtures) and a price per area (eg, building exterior panels, glass for exterior walls, and exterior painting). can As a modified example, the price per area may be calculated according to a rule set in advance in consideration of the size and area of the building even in the case of an exterior entrance door and an exterior lighting device. Table 2 below illustrates these prices.

building exterior panels
(per ㎡) glass for exterior walls
(per ㎡) exterior painting
(per ㎡) exterior lighting fixtures
(per dog) exterior access door
(per dog) Class A 30000 ... ... ... ... Class B 25000 ... ... ... ... Class C 20000 ... ... ... ...

In step 35), the virtual reality server 100 calculates the total investment amount by summing the additional investment amount and the basic investment amount.

For example, if the basic investment amount is 1.5 billion won and the additional investment amount is 500 million won, the total investment amount is calculated as 2 billion won.

More specifically, the input of the remodeling simulation information in step 32) may be executed as follows.

In step 321, the virtual reality server 100 visually displays the selected building on the screen of the user client 200 in a virtual reality environment based on BIM (Building Information Modeling) information of the selected building.

In step 322, the virtual reality server 100 provides the user client 200 with a remodeling option menu for exterior elements or interior elements constituting the selected building.

The remodeling option menu includes a plurality of options for remodeling exterior elements or interior elements, and cost information for each option is included.

For example, a plurality of options for remodeling exterior elements are configured to select at least a type of exterior material, and the quantity/area of exterior materials may be input. These options may be configured in the form of an option menu so that the user selects and inputs them.

For example, the plurality of options for remodeling interior elements are configured to select at least the type of interior materials, and the quantity/area of interior materials may be input.

In step 323, the virtual reality server 100 receives building interior remodeling information or building exterior remodeling information from the user client 200 based on the remodeling option menu.

Building interior remodeling information is information for selecting an option for remodeling interior elements, is input based on the option menu, includes information on selecting at least the type of interior materials, and includes information on the quantity/area of interior materials. may also include

The building exterior remodeling information is information for selecting an option for remodeling exterior elements, is input based on the option menu, includes at least information about selecting the type of exterior material, and includes information on the quantity/area of the exterior material. may be

Based on the building interior remodeling information or the building exterior remodeling information, a remodeling simulation result may be calculated as follows.

For example, the quantity or area of interior materials may be input by a user through an option menu, or may be automatically calculated based on BIM (Building Information Modeling) information of a selected building. For example, the required amount of flooring material and wallpaper may be automatically calculated based on the type of interior materials input through the option menu and the floor area, wall area, and number of floors of the building. In addition, the number of lighting fixtures may be automatically calculated based on the type of interior materials input through the option menu and the floor area of the building. Also, the number of doors may be automatically calculated based on the type of interior materials input through the option menu and the number of rooms in the building.

For example, the quantity or area of exterior materials may be input by the user through an option menu, or may be automatically calculated based on BIM (Building Information Modeling) information of a selected building. For example, the required amount of the building exterior panel, the exterior wall glass, and the exterior painting may be automatically calculated based on the type of exterior material input through the option menu, the area of the floor, the area of the exterior wall, and the number of floors of the building. In addition, the number of external lighting fixtures may be automatically calculated based on the type of exterior material input through the option menu and the floor area of the building. In addition, the number of exterior doors may be automatically calculated based on the type of exterior material input through the option menu and the structure of the building.

When the third option is input in step 2), step 3) may be executed as follows.

In step 31'), the virtual reality server 100 provides the user client 200 with a reconstruction simulation mode for the selected building. The reconstruction simulation mode is provided in the form of a user interface (UI) through which reconstruction simulation information can be input.

In step 32'), the virtual reality server 100 receives reconstruction simulation information for the selected building from the user client 200 in the reconstruction simulation mode.

The reconstruction simulation information includes reconstructed building structure information, reconstructed building interior information, and reconstructed building exterior information.

The structure information of the reconstructed building is input to simulate a building structure type, number of floors, building construction cost, etc. for constructing a building structure environment of a virtual reconstructed building. The building structure type may include a normal building structure type capable of generating rental income, such as a commercial building, an officetel, and a mixed-use building.

The interior information of the reconstructed building and the exterior information of the reconstructed building may be configured in the same or similar form as the above-described building interior remodeling information and building exterior remodeling information, and duplicate descriptions are omitted.

In step 33'), the virtual reality server 100 provides the user client 200 with a simulation result in which the selected building is reconstructed in a virtual reality environment based on the input reconstruction simulation information.

For example, a reconstruction simulation result is provided based on information about a land area to be reconstructed and input reconstruction simulation information. For example, by arranging architectural structural elements (eg, columns, walls, floors, doors, etc.) based on preset building simulation rules, a virtual reconstructed building object (including exterior and interior) is visually implemented in a virtual reality environment. . In addition, a state in which interior and exterior materials included in the reconstruction simulation information are virtually arranged or installed based on preset interior and exterior simulation rules is visually simulated and implemented.

Building simulation rules are used to determine, for example, the shape of the building structure, the number of rooms, the location and number of stairs/elevators, the location/number of doors, etc. based on the size and shape of the land area, the type of building structure and the number of floors. It can be understood as a rule for

For example, if the building structure type is a commercial building, the number of floors of the building is 10, and the land area to be reconstructed has a square shape and an area of 1000 m2, based on the building simulation rules pre-managed by the virtual reality server 100 The layout of architectural structural elements (eg, columns, walls, floors, doors, etc.) is determined, and accordingly, the shape of the architectural structure, the number of rooms, the location and number of stairs/elevators, and the location of doors to realize a virtual reconstructed building. / The number, etc. is determined. These building simulation rules may be managed in the virtual reality server 100 based on, for example, an analysis result derived with the largest number of case values for each condition by statistically analyzing actual building data. As another example, the arrangement of building structural elements may be determined using an artificial neural network trained by using a building structure type, number of floors, land area shape, area, actual structure of a building, etc. as learning values. Building simulation rules may be set by the manager client 300 .

Since the interior/exterior simulation rules may be configured in the same or similar form as the simulation rules of the above-described remodeling simulation process, duplicate descriptions are omitted.

In step 34'), the virtual reality server 100 calculates an additional investment amount based on the reconstruction simulation information.

For example, the additional investment amount is calculated by adding up the cost required for constructing the building structure, the cost required for the interior of the building, and the cost required for the exterior.

The cost required for constructing a building structure is determined based on the size and shape of the land area, the type and number of building structures and the building simulation rules, the number of rooms, the location and number of stairs/elevators, and the location/number of doors. It is calculated using information about the number and standard construction cost information managed by the virtual reality server 100 .

The cost required for building interior and exterior may be calculated in the same or similar form to the cost required for interior and exterior remodeling of the building in the above-described remodeling simulation process, so duplicate descriptions are omitted.

Standard construction cost is a construction cost index that integrates fluctuations in material and labor costs according to the weight of the standard construction cost by setting the cost composition of the standard construction cost according to the main use and structure of the building. used for In the present embodiment, the standard construction cost of the government notification may be used, or the standard construction cost set by itself in a similar form may be input and used by applying it.

In particular, since the reconstruction simulation is a method of demolishing an existing building and constructing a new building, it is desirable to add the demolition cost of the existing building together when calculating the standard construction cost.

In step 35'), the virtual reality server 100 calculates the total investment amount by summing the additional investment amount and the basic investment amount.

For example, if the basic investment amount is 1.2 billion won and the additional investment amount is 800 million won, the total investment amount is calculated as 2 billion won.

More specifically, the input of the reconstruction simulation information in step 32') may be executed as follows.

In step 321', the virtual reality server 100 visually displays the land area from which the selected building is virtually removed on the screen of the user client 200 based on the geographic information.

In step 322', the virtual reality server 100 provides a building structure option menu to the user client 200 based on the size and shape conditions of the land area.

The building structure option menu includes a plurality of options for setting the building structure type and the number of floors of the building, and cost information for each option is included.

The required cost information for each option may be provided by calculating an estimated cost based on the building structure type and the number of floors of the building based on standard construction cost information.

In step 323', the virtual reality server 100 receives reconstructed building structure information including building structure type information and building number information from the user client 200 based on the building structure option menu.

In step 324', the virtual reality server 100 provides a reconstruction option menu for exterior elements and interior elements constituting the reconstructed building to the user client 200 based on the structure information of the reconstructed building.

The reconstruction option menu each includes a plurality of options for installing exterior elements or interior elements, and cost information for each option is included.

Since the reconstruction option menu may be configured in the same or similar form to the above-described remodeling option menu, duplicate descriptions will be omitted.

Preferably, when the reconstruction option menu is provided, a virtual reconstructed building may be visually displayed in a virtual reality environment based on the structure information of the reconstructed building and provided to the user client 200 .

In step 325', the virtual reality server 100 receives interior information of the reconstructed building and exterior information of the reconstructed building from the user client 200 based on the reconstruction option menu.

Since the interior information of the reconstructed building and the exterior information of the reconstructed building may be input in the same or similar form to the above-described building interior remodeling information or building exterior remodeling information, a duplicate description is omitted.

Meanwhile, as a modified example, in step 1), the virtual reality server 100 may be configured to receive input of the upper limit amount of investment together with the basic investment amount from the user client 200 .

In this case, in step 3), when the total investment amount calculated based on the investment simulation result exceeds the upper limit of the investment, the investment simulation mode is executed again and provided.

The upper limit of investment may be understood as an amount of money the user can hold for real estate investment or an amount input and set by the user in consideration of this.

As described above, the basic investment amount is an amount considering only the amount required for the purchase of the building without reflecting the cost of remodeling or reconstruction.

If the user wants to earn rental income as it is in the original building purchased without considering remodeling or reconstruction, additional investment other than the basic investment may not be required.

However, if the user considers remodeling or reconstruction, the remodeling cost or reconstruction cost is added to the basic investment amount, and if the sum of the basic investment amount and the additional investment amount exceeds the user's possible holding amount for real estate investment, the user's Simulation results may be unrelated to actual investment.

Considering this, in this embodiment, the investment upper limit is input together with the basic investment amount, and when the total investment amount calculated based on the investment simulation result exceeds the investment upper limit, the investment simulation mode is provided again, Controls so that the sum of the basic investment amount and the additional investment amount does not exceed the amount that the user can hold for real estate investment.

As another modified example, in step 1), the virtual reality server 100 may be configured to receive a condition for infringement of the right to sunlight together with the basic investment amount from the user client 200 .

In this case, in step 2), if the virtual reality server 100 determines that the building selected for investment review corresponds to the conditions for violating the right to sunlight as a result of simulation of the right to sunlight in a virtual reality environment in a three-dimensional coordinate space, investment review Ask to reselect another building as the target.

Depending on the user's personal inclination or investment conditions, there are cases in which the right to sunlight of the invested building should not be infringed. For example, when a user who uses a building corresponds to an industry in which normal work is difficult under conditions of infringement of the right to sunlight, or when there is concern about property damage of the building due to infringement of the right to sunlight.

In view of this, in the present embodiment, through the reselection request process, other buildings that do not fall under the conditions for violating the right to sunlight can be newly reviewed.

For example, the shadow 20' of the nearby building 10' generated according to the irradiation direction of the virtual sunlight SL in the three-dimensional coordinate space is the subject of investment review. Excess time (eg, 6 hours) in which the size of the invasion area DA' invading the floor area 12 of the selected building 10 exceeds a predetermined ratio (eg, 30%) of the size of the floor area 12. If it is more than a predetermined time (eg, 4 hours) during the day, it is determined that the above-mentioned right infringement condition is met. This case is illustrated in FIG. 5 . The rate condition and the time condition can be changed and set by the user client 200 or the manager client 300 .

For example, the building 10 in virtual reality may be a 3D object implemented based on a polygon mesh based on geographic information and building information. A vertex is a single point with a location in the 3D space, an edge is a straight line connecting vertices and vertices, and a polygon is a face composed of three or more vertices. A collection of these to form a 3D object is called a polygon mesh. A polygon mesh can be seen as defining an object in a three-dimensional space.

The shadow 20 may be configured to be displayed only on the ground (floor) of virtual reality. In this case, the shadow 20 may be implemented as a 3D object based on a polygon mesh, or a 2D flat object. It can also be implemented in the form of

To this end, the shadow 20 is formed in real time or according to a predetermined cycle based on the position of the virtual sun S in virtual reality, the geographical position (latitude, longitude) of the building 10, date, time, etc. direction may change.

The virtual reality server 100, within the three-dimensional coordinate space implemented in virtual reality, arranges the shadow 20 whose length is adjusted on the floor surface in the direction opposite to the irradiation direction of the virtual sunlight SL and gives it a color. to indicate

4 illustrates variously displayed shadows 20 according to the irradiation direction of the virtual sunlight SL.

As another example, when the shadows 20' and 20'' of two or more neighboring buildings 10' and 10'' respectively invade the floor area 12 of the building 10 selected for investment review, each The overtime (eg, 3 hours, 5 hours) is calculated for each nearby building, and the cumulative sum of the calculated overtime (eg, 8 hours) for each nearby building exceeds a predetermined time (eg, 6 hours) of the day. In this case, it is determined that the conditions for infringement of the right to sunshine are met. This case is illustrated in FIG. 6 . This configuration is preferable when there are many high-rise buildings in the vicinity of the building 10 selected for investment review.

As another example, whether or not the conditions for violating the right to sunlight are determined based on a reference date (eg, summer solstice, winter solstice) and a reference time (eg, noon) input from the user client 200, in a 3D coordinate space. The shadow 20' of the nearby building 10' generated according to the irradiation direction of the sunlight SL of the invasion area DA'- When the ratio of the size of 1) to the size of the floor area 12 is equal to or greater than a predetermined ratio (eg, 60%), it is determined that the condition for violating the right to sunlight is met. This case is illustrated in FIG. 7 . This configuration is preferable when the building 10 selected for investment review should not be infringed on the right to sunlight on a specific date or time of the year.
