[0001] The present invention relates to a method and a program for renovating a house.

Background Art

[0002] When the family composition changes due to marriage, childbirth, cohabitation, separation or bereavement, etc., it is desirable that each of the residents of the house can live comfortably and pleasantly. Patent Document 1 discloses a technique for improving the heat insulation performance of an existing outer wall of a building by installing a heat insulating material corresponding to the heat insulation performance of the existing outer wall of the building on the existing outer wall. Improving the heat insulation performance of the existing outer wall makes the residents comfortable through temperature control of the space inside the building. However, if heat insulating materials are installed on the entire existing outer wall of the building, the renovation cost will increase. If heat insulating materials are installed on the existing outer wall in contact with a room with reduced usage frequency, that renovation will be wasted.

[0042] <2. Renovation Floor Plan Presentation System> The resident of House 1 desires renovations to House 1 and consults with a renovation company regarding the renovations. At this time, the renovation company's representative presents the client with proposed floor plans after the renovations and explains the estimated renovation costs and renovation plans using the renovation floor plan presentation system shown in Figure 2. The renovation floor plan presentation system is operated by the renovation company.

[0043] The renovation floor plan presentation system includes a terminal device 200 and an information processing device 220.

[0044] The terminal device 200 is a computer-based device such as a smartphone, tablet computer, or laptop computer. The terminal device 200 includes a CPU, GPU, memory, storage, input devices, display devices, imaging devices, and communication devices. Various programs constituting the OS (Operating System) are installed on the terminal device 200. The OS may be a general-purpose OS such as Windows®, Android®, iOS®, macOS®, Linux®, or Unix®. Application programs executable on the OS are installed on the terminal device 200. The terminal device 200 is used by a vendor's representative or consultant.

[0045] Terminal device 200 is connected to the internet 210. Terminal device 200 accesses the information processing device 220 via the internet and logs into an account using the login information of the vendor's representative or consultant. Terminal device 200 communicates with the information processing device 220 via the internet 210. This communication function of terminal device 200 is implemented by an application program running on terminal device 200. The application program is configured with the login information of the account assigned to the vendor's representative or consultant.

[0046] The information processing device 220 is a server or host machine configured with computers. The information processing device 220 may consist of a single computer system, or it may consist of multiple computer systems capable of distributed or parallel processing. The information processing device 220 may also be a cloud computing system. Executable programs for the information processing device 220 are installed on the information processing device 220.

[0047] The operation and usage methods of the terminal device 200 and the information processing device 220 will be explained. When the person in charge or the person seeking advice has the terminal device 200 run the application program, the terminal device 200 starts the application program. The terminal device 200 displays a GUI (Graphical User Interface) screen provided by the application program. When the person in charge or the person seeking advice operates the terminal device 200 and commands it to input the current floor plan on the GUI screen, the terminal device 200 starts the imaging device. The person in charge or the person seeking advice takes a picture of the floor plan of house 1 using the terminal device 200. The terminal device 200 takes a picture of the floor plan of house 1 and acquires an image of the floor plan. If the floor plan is photographed from an oblique angle, the terminal device 200 may perform trapezoidal correction on the image of the floor plan. As shown in Figure 3, the terminal device 200 displays the image of the floor plan on the GUI (Graphical User Interface) screen provided by the application program.

[0048] Alternatively, the design data for House 1 or a standardized house may be pre-stored in the storage medium of the terminal device 200, and the terminal device 200 may generate an image of the floor plan from the design data. This floor plan image may be either a raster image or a vector image. Alternatively, the image of the floor plan for House 1 or a standardized house may be pre-stored in the storage medium of the terminal device 200, and the terminal device 200 may read the image of the floor plan from the storage medium. This floor plan image may be either a raster image or a vector image.

[0049] Next, the person in charge or the person seeking advice operates the terminal device 200 and enters the type of the main living area in the house on the GUI screen. The terminal device 200 acquires this input. The type of main living area in the house can be selected from one or more options, such as "living room," "living room and dining room," "dining room," "dining room and kitchen," "living room, dining room, and kitchen," "Western-style room," "Japanese-style room," and "bedroom." Two or more of the same type may be selected.

[0050] Next, the person in charge or the person seeking advice operates the terminal device 200 and inputs the type of interior space to be included in the insulated area on the GUI screen. The terminal device 200 acquires this input. The types of interior spaces to be included in the insulated area can be selected from, for example, "laundry room with integrated bathroom," "laundry room with separate bathroom," "laundry room," "toilet room," "bathroom," "kitchen," "pantry," "storage room," "entrance," "corridor," and "staircase," with one or more options available. Two or more of the same type may be selected.

[0051] Next, the person in charge or the person seeking advice operates the terminal device 200 and inputs the type of interior space to be included in the non-insulated area on the GUI screen. The terminal device 200 acquires the input. The types of interior spaces to be included in the non-insulated area can be selected from, for example, "laundry room with integrated bathroom," "laundry room with separate bathroom," "laundry room," "toilet room," "bathroom," "kitchen," "pantry," "storage room," "entrance," "corridor," "stairs," "living room," "living room / dining room," "dining room," "dining room / kitchen," "living room / dining room / kitchen," "Western-style room," "Japanese-style room," and "bedroom." Two or more of the same type may be selected.

[0052] Next, the person in charge or the person seeking advice operates the terminal device 200 and inputs housing information on the GUI screen. The terminal device 200 then retrieves the input information. Housing information includes, for example, the completion date of house 1 (year, year, year and month or year and month and day), the type of equipment in house 1, the type of insulation method used in house 1, whether or not house 1 has undergone past renovations, the timing of past renovations of house 1 (year, year, year and month or year and month and day), or the type of standardized house.

[0053] Once the above input is complete, the terminal device 200, the entered floor plan image, the type of residential area, the type of residential area to be included in the insulated area, the type of residential area to be included in the non-insulated area, and the housing information are transmitted to the information processing device 220. The information processing device 220 receives the information transmitted by the terminal device 200 and stores it in association with the account information.

[0054] Next, the information processing device 220 recognizes the floor plan of house 1 or a standard house by image recognition processing of the floor plan image. In other words, the information processing device 220 recognizes the attributes and arrangement of elements in the floor plan image. An element refers to an area that occupies a predetermined range within the floor plan image. The attribute of an element indicates what that element depicts. For example, the attribute of the area occupying the Japanese-style room 24 in the floor plan image is "Japanese-style room" or "living room". The arrangement of an element indicates the position and range in which the element is drawn within the image. The information processing device 220 stores the data of the element's attributes and arrangement in association with the information transmitted from the terminal device 200 and the account information.

[0055] Next, the information processing device 220 generates an image of the renovated floor plan and design data related to the renovation based on the input floor plan image, element attributes and arrangement, type of interior space mainly occupied, type of interior space to be included in the insulated area, type of interior space to be included in the uninsulated area, and housing information. For example, the information processing device 220 may input the input floor plan image, element attributes and arrangement, type of interior space mainly occupied, type of interior space to be included in the insulated area, type of interior space to be included in the uninsulated area, and housing information into a machine learning model, and output an image of the renovated floor plan and design data related to the renovation from the machine learning model. The machine learning model is an artificial intelligence model that has been deeply trained using floor plan images, element attributes and arrangement, type of interior space mainly occupied, type of interior space to be included in the insulated area, type of interior space to be included in the uninsulated area, housing information, image of the renovated floor plan, and design data related to the renovation that have been collected in the past. Furthermore, the information processing device 220 may further train a machine learning model based on the input floor plan image, element attributes and arrangement, type of residential area, type of residential area to be included in the insulated area, type of residential area to be included in the non-insulated area, housing information, image of the renovated floor plan, and design data related to the renovation.

[0056] The design data for the renovation may include at least one of the following: floor area of ​​the insulated area, floor area of ​​the non-insulated area, insulation performance, and estimated renovation cost. In the image of the floor plan after renovation, the insulated area with improved insulation performance and the non-insulated area without are visually distinguishable. The insulated area is grouped together without being divided. The insulated area includes the input type of interior partition, i.e., the "primarily occupied interior partition" and the "interior partition to be included in the insulated area." The non-insulated area includes the input type of interior partition, i.e., the "interior partition to be included in the non-insulated area." It includes.

[0057] Next, the information processing device 220 stores the image of the renovated floor plan and the design data related to the renovation, associating them with the information transmitted from the terminal device 200 and the account information. Next, the information processing device 220 transmits an image of the renovated floor plan and the design data related to the renovation to the terminal device 200. The terminal device 200 receives the image of the renovated floor plan and the design data related to the renovation.

[0058] Next, as shown in Figure 4, the terminal device 200 displays an image of the renovated floor plan on a GUI (Graphical User Interface) screen created by an application program. The image of the renovated floor plan shown in Figure 4 is generated based on the image of the pre-renovation floor plan shown in Figure 3. In the image of the floor plan shown in Figure 4, the areas with a dot pattern are insulated areas, and the areas without a dot pattern are non-insulated areas. The types of rooms in the house where people mainly live are selected as "living room / dining room" and "bedroom". The types of rooms to be included in the insulated area are selected as "kitchen", two "storage rooms", "toilet room", "laundry room with integrated washroom", "bathroom", and "corridor". The types of rooms to be included in the non-insulated area are selected as "entrance", "corridor", "stairs", and "Western-style room". Therefore, in the image of the floor plan shown in Figure 4, the "living room / dining room", "bedroom", "kitchen", two "storage rooms", "toilet room", "laundry room with integrated washroom", "bathroom", and "corridor" are included in the insulated area, and the "entrance", "corridor", "stairs", and "Western-style room" are included in the non-insulated area.

[0059] The terminal device 200 may display images of the floor plan before and after renovation. This allows the client to compare the floor plans before and after renovation. The terminal device 200 may display design data related to the renovation, namely the floor area of ​​the insulated area, the floor area of ​​the non-insulated area, the insulation performance, and the estimated renovation cost. The terminal device 200 may also display the insulation performance before and after the renovation. The insulation performance may be expressed using household indicators such as energy costs.

[0060] Furthermore, the application program of the terminal device 200 may cause the terminal device 200 to perform the same processing as the information processing device 220, as described above.

[0061] <3. Renovation methods and the renovated house> Figure 5 is the floor plan of the first floor of house 1A after renovation. House 1A is a renovation of House 1 based on the floor plan proposed by the system described above, involving a change in the layout of the first floor of the existing House 1, and a partial improvement in the thermal insulation performance of the modified first floor. The renovation results in an improvement in the thermal insulation performance of the first floor of the existing House 1. The renovation is a partial thermal insulation renovation of the first floor, not a complete renovation of the entire first floor. In other words, the renovation does not improve the thermal insulation performance of the entire first-floor space of House 1, but improves a part of the first-floor space. In Figure 5, the areas marked with a dot pattern are areas where the thermal insulation performance has been improved by the renovation. These areas are called thermal insulation areas. The thermal insulation performance of the areas marked with a dot pattern has not been improved. These areas are called non-thermal insulation areas.

[0102] <4. Summary> (1) As explained above, by renovating House 1, which involves changing the floor plan of House 1 and improving the partial insulation performance of the modified floor plan, the modified floor plan is divided into an insulated area with improved insulation performance and an uninsulated area. Because this renovation involves changing the floor plan, the interior space of the renovated House 1A is effectively utilized according to the lifestyle patterns of the residents, allowing them to live comfortably and pleasantly. The insulated area with improved insulation performance makes the residents living there comfortable by maintaining a constant temperature in that area. Because an uninsulated area is set in the floor plan with only a partial improvement in the insulation performance of the modified floor plan, the renovation can be carried out at low cost and without waste.

[0103] (2) In the revised floor plan, the washroom 29A, toilet room 28A, bathroom 30A, and living room 25A will be placed within the insulated area, and the passageway 93A connecting the washroom 29A, toilet room 28A, bathroom 30A, and LDK 25A will be set within the insulated area without having to leave the insulated area due to the floor plan changes. Such renovations will contribute to residents being able to live comfortably and pleasantly.

[0104] (3) In the revised floor plan, the washroom 29A, toilet room 28A, bathroom 30A, LDK 25A, and corridor 62A are placed within the insulated area. The passageway 93A connecting the washroom 29A and LDK 25A is set to corridor 62A without leaving the insulated area due to the floor plan change. The passageway 93A is extended through the washroom 29A to the toilet room 28A and bathroom 30A without leaving the insulated area due to the floor plan change. Thus, the residents can live comfortably and pleasantly.

[0105] (4) Replace the windows in the washroom 29A, bathroom 30A, and living room / dining room / kitchen 25A with windows 42A, 43A, 44A, 56A, and 61A, which have higher thermal insulation performance. This will contribute to dividing the first floor into insulated and non-insulated areas.

[0106] (5) Install insulation material under the floor of the insulated area. This helps to divide the floor plan into insulated and non-insulated areas.

[0107] (6) Install insulation material behind the ceiling of the insulated area. This helps to divide the area into an insulated area and an uninsulated area.

[0108] (7) During the renovation, insulation material is installed at the boundary between the insulated area and the non-insulated area. Specifically, insulation material is filled into the south-facing portion of the partition wall 60A that is the bathroom 30A, into the west-facing portion of the partition wall 57A that is the toilet room 28A, into the partition wall 54A, into the partition wall 35A, and into the partition wall 70A. Thus, the insulated area and the non-insulated area are thermally insulated by this insulation material.

[0109] (8) The improved insulation performance of the insulated areas reduces the energy consumption of cooling or heating used within those areas. Renovations that involve improving the partial insulation performance of the floor plan contribute to promoting carbon neutrality, realizing a decarbonized society, and achieving the Sustainable Development Goals (SDGs). Renovated House 1A is easier to use than House 1 before renovation, and House 1A also has a longer lifespan. Therefore, the renovation of House 1 contributes to promoting carbon neutrality, realizing a decarbonized society, and achieving the SDGs through the effective use of housing infrastructure.
