Summary of the Invention

Problems to be Solved by the Invention

[0007] Incidentally, in architectural design, a common design process involves the designer creating a detailed building model, determining the performance values ​​for each part of the building, and then determining the design specifications that satisfy those performance values. The building model is typically realized using, for example, a 3D BIM (Building Information Modeling) model.

[0008] Under the circumstances in which such a design process is employed, if, for example, the detailed building model is changed due to a design change, it becomes necessary to re-determine the performance values ​​of each part of the building and consider design specifications that satisfy those performance values.

[0009] On the other hand, much of a building's performance can be determined by the boundaries between rooms and between rooms and the outside. For example, the sound insulation performance of the wall between room A and room B is determined according to the required sound insulation performance for those rooms, and the design specifications of the wall that meets that performance are determined. Similarly, the exterior specifications of a building correspond to the design specifications of the boundary area between a room and the outside (e.g., the roof and exterior walls).

[0010] Furthermore, various calculations are necessary when determining the design specifications of a building. For example, it may be necessary to perform various calculations related to Zero Energy Buildings (ZEB) when determining the design specifications of a building. Since the building's design specifications must be determined in order to perform such energy calculations or heat load calculations related to the building, it is difficult to perform energy calculations or heat load calculations in the early stages of the design process.

[0011] Although the above-mentioned Patent Documents 1-4 disclose technologies related to BIM models, they do not consider how to efficiently perform various energy calculations and heat load calculations related to buildings.

[0012] This invention has been made in view of the above facts, and aims to efficiently calculate the energy or heat load related to the building under design. [Means for solving the problem]

[0013] To achieve the above objective, the design support device of the present invention includes an acquisition unit that acquires a room zone model representing the arrangement of rooms within a building to be designed, and a generation unit that generates a performance definition model, which is a model representing the performance of the room boundaries in the building to be designed and a model for defining the performance of the building to be designed, based on the room zone model acquired by the acquisition unit. The design support device includes a setting unit that sets the design specifications of the target building based on the performance definition model generated by the generation unit, and a calculation unit that calculates the energy or heat load related to the target building based on the performance definition model generated by the generation unit and the design specifications of the target building set by the setting unit. This allows for efficient calculation of the energy or heat load related to the target building. [Effects of the Invention]

[0014] According to the present invention, the energy or heat load related to the building under design can be efficiently calculated. [Brief explanation of the drawing]

MODE FOR CARRYING OUT THE INVENTION

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0017] <Overview of the Present Embodiment> First, the overview of the present embodiment will be described. FIG. 13 is a diagram for explaining a conventional method. As shown in FIG. 13, conventionally, in Phase 1 of building design (denoted as "1ph" in FIG. 13), when a room zone model representing the layout of rooms in the building to be designed and room information indicating what types of rooms are included in the room zone model are created, the architectural designer performs operations such as creating a color-coded diagram, creating a working drawing, and considering the area based on the room zone model and the room information. Also, the facility / environment designer performs operations such as creating a color-coded diagram, plotting equipment, plotting the ceiling, proposing routes, and conducting system studies.

[0018] And, as shown in FIG. 13, in Phase 2 of building design (denoted as "2ph" in FIG. 13), when a detailed building model and a detailed facility model are created, the design specifications are determined (for example, selecting the specifications of the inner wall, etc.) and various calculations (for example, noise calculation, etc.) are performed based on the models.

[0019] Therefore, as shown in Figure 13, in conventional architectural design processes, the designer often creates a detailed building model, then determines the performance values ​​for each part of the building, and finally determines the design specifications that satisfy those performance values.

[0020] For example, consider the case where the sound insulation performance of a wall between two rooms, A and B, within a building is determined. In this case, first, the designer creates a detailed building model (architectural model and equipment model) representing the building under design. This detailed building model reflects, for example, the provisional design specifications of the wall between rooms A and B, and provisionally determines the wall thickness between the rooms. Next, according to the required sound insulation performance for rooms A and B, the sound insulation performance of the wall between rooms A and B is determined, and the design specifications of the wall that satisfy that sound insulation performance are determined.

[0021] For example, a performance value of 65 [dB] is set to represent sound insulation performance, and the design specifications for a wall that meets this performance value of 65 [dB] are set to be such that the design specifications (for example, rock wool, wall thickness D [mm]) meet this performance value.

[0022] If such a design process is adopted, for example, if the detailed building model is changed due to design modifications, and the thickness of the wall between room A and room B is changed, or if the room layout is altered, the sound insulation performance and design specifications of the wall between room A and room B must be re-examined. On the other hand, much of a building's performance can be determined by the boundaries between rooms and the boundaries between rooms and the outside.

[0023] Therefore, in this embodiment, a performance definition model is set up, which is a model that represents the boundaries of a building and is also a model for defining the performance of the building, and the building is designed by utilizing this performance definition model.

[0024] Figure 1 is a diagram illustrating the performance definition model of this embodiment. As shown in Figure 1, in this embodiment, multiple types of performance definition models M are generated from a room zone model (and room information) that represents the arrangement of rooms within a building, representing the boundaries between rooms and the boundaries between rooms and the outside. In the example shown in Figure 1, the multiple types of performance definition models M include, as an example, an exterior wall model, an interior wall model, a roof / earthquake / floor model, an opening range model, a perimeter model, and an eaves model. These performance definition models M are BIM models that correspond to the boundary portions of the building.

[0025] Figure 2 is a diagram illustrating the generation of the performance definition model and the setting of various calculations and design specifications in this embodiment. As shown in Figure 2, in this embodiment, once a room zone model is created and room information is set, multiple types of performance definition models are automatically generated. Figure 2 shows, as an example of multiple types of performance definition models, a ground surface model, an exterior wall surface model, a roof surface (per room) model, an interior wall surface model, an exterior wall surface (floor) model, an exterior soffit model, an interior floor surface model, a soffit surface model, a roof surface model, an opening range model, an exterior wall surface model, and a perimeter model. It is also possible to generate other types of performance definition models by combining these multiple types of performance definition models.

[0026] As shown in Figure 2, once multiple types of performance definition models are generated, performance values ​​are set for each aspect of these multiple types of performance definition models. As mentioned above, much of a building's performance can be determined by the boundaries between rooms and the boundaries between rooms and the outside; therefore, performance values ​​are set for each aspect of the multiple types of performance definition models that correspond to the building's boundaries. The setting of these performance values ​​can be done automatically, semi-automatically, or manually. When the values ​​are set automatically or semi-automatically, performance values ​​may be set for each aspect of the multiple types of performance definition models depending on the type of space constituting the boundary between rooms or the boundary between rooms and the outside (for example, the use of the room or the outside).

[0027] Figure 3 is a diagram illustrating the workflow when using the design support system of this embodiment. As shown in Figure 3, when using the design support system of this embodiment, multiple types of performance definition models are automatically generated when a room zone model is created. Specifically, multiple types of performance definition models are automatically generated by referring to the information of each part of the room zone model. Then, as shown in Figure 3, performance values ​​are set for each surface of the multiple types of performance definition models, and design specifications that satisfy those performance values ​​are set. In this embodiment, performance values ​​are added to each part of the performance definition model as described above. In addition, boundary-independent performance values ​​(for example, customer-specified performance values) are also added to the performance definition model. Architectural designers and equipment environment designers proceed with creating architectural models and equipment models by modeling the set design specifications. Architectural designers and equipment environment designers also perform verification work on the setting of performance values ​​and the modeling of design specifications. By using this performance definition model, it becomes possible to perform various calculations for determining the building's design specifications at an early stage, thereby enabling the building's design specifications to be determined early.

[0028] Specifically, as shown in Figures 1 and 2, it becomes possible to perform sound insulation studies and noise calculations based on the performance values ​​added to the performance definition model, and based on the results, it becomes possible to determine the building's design specifications at an early stage. Furthermore, the performance values ​​added to the performance definition model will not change unless the room zone model and room information are changed, in principle. Therefore, even if the initial building model is changed due to design changes, etc., if the change does not affect the room zone model and room information, various calculations can be performed using the initially set performance definition model. For this reason, even if the initial building model is changed, it is not necessary to reconsider the performance values, and the building design work can proceed smoothly.

[0029] Furthermore, in this embodiment, a performance-defined model is used for various calculation tools and thermal load calculations when designing a building with Zero Energy Building (ZEB) in mind. This makes it possible to efficiently perform various calculations related to Zero Energy Building (ZEB) (hereinafter simply referred to as "ZEB-related calculations") and thermal load calculations. Specifically, it becomes possible to perform ZEB-related calculations at an early stage without waiting for the completion of a detailed building model.

[0030] <Configuration of the design support system according to the embodiment> Figure 4 shows an example of the configuration of the design support system 10 according to the embodiment. Functionally, the design support system 10 can be represented as a configuration including a user terminal 12 and a design support device 14, which is a computer, as shown in Figure 4. The user terminal 12 and the design support device 14 are connected to each other via, for example, a communication means 16.

[0031] (User terminal 12) The user terminal 12 is operated by a user. The user is, for example, an architect, structural engineer, or building environment engineer. The user terminal 12 exchanges information with the design support device 14.

[0032] The design support device 14 and user terminal 12 are composed of a computer 50 that includes a CPU (Central Processing Unit), ROM (Read Only Memory) storing programs for realizing each processing routine, RAM (Random Access Memory) for temporarily storing data, memory as a storage means, and a network interface. As shown in Figure 5, the computer 50 that constitutes the design support device 14 and user terminal 12 includes a CPU 51, memory 52 as a temporary storage area, and a non-volatile storage unit 53. The design support device 14 and user terminal 12 also include an input / output interface (I / F) 54 to which input / output devices (not shown) are connected, and a read / write (R / W) unit 55 that controls the reading and writing of data to the recording medium 59. The design support device 14 and user terminal 12 also include a network I / F 56 that connects to a network such as the Internet. The CPU 51, memory 52, storage unit 53, input / output I / F 54, R / W unit 55, and network I / F 56 are connected to each other via a bus 57.

[0033] The storage unit 53 can be implemented using a Hard Disk Drive (HDD), Solid State Drive (SSD), flash memory, etc. The storage unit 53, as a storage medium, stores programs that enable the computer to function. The CPU 51 reads the programs from the storage unit 53, loads them into memory 52, and sequentially executes the processes contained within the programs.

[0034] In this embodiment, we will explain the case where the external specifications of a building are set as an example of design specifications. Figure 6 is a diagram illustrating the flow when the external specifications of a building are set. As shown in Figure 6, when a building plan is created, a building model that satisfies the building plan is created. This building model is a BIM model that realizes the outline of the building and includes a room zone model and room information. Next, a performance definition model is generated by the automatic recognition of the room zone model and room information included in the building model. Then, the BIM model incorporating this performance definition model is presented to the user, and the design specifications are determined. The details will be explained below.

[0035] As shown in Figure 4, the design support device 14 functionally comprises a data storage unit 130, a performance definition model storage unit 132, an acquisition unit 140, a generation unit 142, a setting unit 144, and a calculation unit 146.

[0036] The data storage unit 130 stores various data related to design support. For example, the data storage unit 130 stores a provisional building model of the building under design. This building model is a BIM model designed by the construction designer, and the exterior surface materials of the building, etc., are already set as provisional design specifications. The data storage unit 130 may also store room zone models and room information representing the layout of rooms within the building under design. For example, the user, an architectural designer, creates a room zone model using CAD and stores the created room zone model in the data storage unit 130. In addition, various other data related to the building under design are stored in the data storage unit 130.

[0037] The performance definition model storage unit 132 stores multiple types of performance definition models generated by the processes described later.

[0038] The acquisition unit 140 acquires a room zone model representing the layout of rooms within the building under design from the data storage unit 130.

[0039] The generation unit 142 generates a performance definition model based on the room zone model acquired by the acquisition unit 140. This model represents the performance of the room boundaries in the building under design and is also a model for defining the performance of the building under design. The generation unit 142 generates multiple types of performance definition models for each of the multiple rooms within the room zone model, according to the type of area adjacent to the room. The generation unit 142 then stores these multiple types of performance definition models in the performance definition model storage unit 132.

[0040] For example, the generation unit 142 generates models for the ground surface, exterior wall surface, roof surface (by room), interior wall surface, exterior wall surface (by floor), exterior soffit model, interior floor surface model, soffit surface model, roof surface model, opening range model, exterior wall surface model, and perimeter model. The required performance values ​​are then added to each surface of these multiple types of performance definition models.

[0041] For example, performance values ​​related to the waterproofing and thermal insulation performance of the roof surface are assigned to each surface of the roof model. These performance values ​​may be calculated from various parameters related to the building model or room zone model, or they may be predetermined by customer specifications. For example, regarding thermal insulation performance, the performance value (e.g., thermal insulation grade) is determined according to the air conditioning load of the indoor space. Regarding waterproofing performance, the performance value is determined based on the building maintenance plan (e.g., waterproofing replacement plan) and the service life (e.g., waterproofing warranty period).

[0042] Furthermore, performance values ​​for thermal insulation and wind pressure are added to each surface of the exterior wall model. Similarly, performance values ​​for thermal insulation and wind pressure are added to the soffit model. In addition, the opening range model is assigned performance values ​​such as the size of the opening, location information (including direction), and the ground height at which the opening is installed.

[0043] Performance values ​​are similarly assigned to each aspect of the other performance definition models. Candidate design specifications that satisfy these performance values ​​are prepared in advance, and the final design specification is determined by the user, as will be described later.

[0044] The setting unit 144 sets the design specifications for the building under design based on the performance definition model generated by the generation unit 142.

[0045] Specifically, first, the setting unit 144 displays a virtual building model, including the generated performance definition model, on the display unit of the user terminal 12. The setting unit 144 also displays candidate design specifications for each face of the performance definition model on the display unit of the user terminal 12.

[0046] Figure 7 shows an example of a screen displayed on the display unit of the user terminal 12. Figure 7 shows the screen used when setting the external specifications for the horizontal surface of a building. As shown in Figure 7, the virtual building model S incorporates a roof surface (per room) model, which is an example of a performance definition model. Also, on the right side of the screen shown in Figure 7, a list of design specification candidates S called "Composition List" is displayed.

[0047] For example, when a user operates the user terminal 12 and selects a roof surface (by room) model, which is an example of a performance definition model, a design specification candidate S called "Composition List" is displayed, as shown in Figure 7. This design specification candidate S is pre-configured to satisfy the performance values ​​attached to each surface of the performance definition model.

[0048] When the design specification candidates S are displayed on the user terminal 12, the user selects the design specification candidate that they deem most suitable for the building from among the design specification candidates S as the official design specification. In the example shown in Figure 7, one of the design specification candidates, composition B (finish: YYYYYY, substrate: concrete type, insulation material), is selected as the official design specification. The user terminal 12 obtains the selection result (composition B) of the design specification candidate selected by the user. The user terminal 12 transmits the selection result (composition B) of the design specification candidate selected by the user to the design support device 14.

[0049] The setting unit 144 of the design support device 14 receives the user's selection result (composition B) of design specification candidates. The setting unit 144 determines the received design specification candidates (composition B) as the design specifications for the building model. For example, the design specifications set for the roof surface (per room) model shown in the figure above are determined as the design specifications for the building's exterior. Other design specifications are determined in the same manner.

[0050] Furthermore, in the above, design specifications are determined for the performance definition models of the horizontal surfaces of the building, namely the ground surface model, the roof surface (per room) model, the soffit model, and the exterior soffit model, while the design specifications for the vertical surfaces of the building (e.g., walls) are determined directly for the building model. Specifically, in such cases, the performance definition model includes a roof model representing the roof of the building under design, a soffit model representing the soffit of the building under design, and a ground surface model representing the surface where the building under design meets the ground. The setting unit 144 displays candidate design specifications for each surface of the building model, which incorporates the roof model, soffit model, and ground surface model, on the display unit of the user terminal 12, obtains the candidate design specification selected by the user, and sets the selected candidate design specification as the design specification for the building under design. In this regard, it is also possible to configure the system so that design specifications are determined for the exterior wall model, which is a performance definition model representing the vertical surfaces of the building.

[0051] Figure 8 shows the screen used to set the exterior specifications (so-called exterior wall specifications) for the vertical surfaces of a building. Similar to Figure 7, Figure 8 shows a virtual building model V. The virtual building model V in Figure 8 incorporates, for example, an exterior wall model (not shown), which is an example of a performance definition model. Also, similar to Figure 7, a list of design specification candidates S, called "Composition List," is displayed on the right side of the screen shown in Figure 8. Similar to Figure 7, the user selects a design specification candidate that they deem suitable for the building from among the design specification candidates S as the official design specification. This determines the design specification for the exterior specifications (so-called exterior wall specifications) of the building's vertical surfaces. The determined design specification is then added to, for example, the performance definition model.

[0052] The calculation unit 146 calculates the energy or heat load related to the building under design based on the performance definition model generated by the generation unit 142 and the design specifications of the building under design set by the setting unit 144.

[0053] Specifically, the calculation unit 146 generates an integrated model for calculating the energy or heat load related to the building under design by integrating the external specifications, which are the external design specifications of the building under design, the opening model, which is a performance definition model, the first interior wall model representing the interior partition walls of the building under design, the second interior wall model representing the interior walls that are in contact with the exterior walls, and the exterior wall model. Then, the calculation unit 146 calculates the energy or heat load related to the building under design based on this integrated model.

[0054] Figure 9 is a diagram illustrating the integrated model. The composite structure or surface material of the exterior wall and the dynamic objects of the opening sash shown in Figure 9 are examples of exterior specifications. Therefore, as shown in Figure 9, the integrated model is generated by integrating the composite structure of the exterior wall, which is an example of exterior specifications, with the opening model, the first interior wall model, the second interior wall model, the exterior wall model, and other information (the "interior finish information stored in the room zone model" and the "geometry of the room zone model" in Figure 9), which are examples of performance definition models. This integrated model can be used as a simulation model for calculating the energy or heat load related to the building under design.

[0055] Figure 10 is a diagram illustrating the computational model of the exterior wall portion realized in the integrated model. As shown in Figure 10, by integrating the exterior wall model with finishing information and the interior wall model with finishing information, a hollow layer as shown in section Z of Figure 10 is virtually realized, making it possible to perform simulations to calculate energy or heat load.

[0056] Therefore, the calculation unit 146 uses this integrated model to calculate the energy or heat load related to the building under design according to known calculation methods. The calculation unit 146 then outputs the calculation results.

[0057] <Function of Design Support System 10> Next, the operation of the design support system 10 of the embodiment will be described. When the design support device 14 of the design support system 10 of the embodiment receives a processing execution instruction signal, it executes the processing routine shown in Figure 11.

[0058] In step S100, the acquisition unit 140 of the design support device 14 acquires a provisional building model of the building to be designed, which is stored in the data storage unit 130.

[0059] In step S101, the acquisition unit 140 of the design support device 14 acquires a room zone model representing the room layout from the building model acquired in step S100. If a room zone model is stored in the data storage unit 130, the acquisition unit 140 may acquire the room zone model from the data storage unit 130.

[0060] In step S102, the generation unit 142 of the design support device 14 generates multiple types of performance definition models based on the room zone model acquired in step S101. Performance values ​​corresponding to the boundaries are added to each surface of the multiple types of performance definition models. Design specification candidates that satisfy these performance values ​​are prepared and presented to the user in step S106, which will be described later.

[0061] In step S104, the setting unit 144 of the design support device 14 causes the virtual building model, including the performance definition model generated in step S102, to be displayed on the display unit of the user terminal 12. For example, the setting unit 144 displays a virtual building model V, such as the one shown in Figure 7 or Figure 8, on the display unit of the user terminal 12.

[0062] In step S106, the setting unit 144 of the design support device 14 displays candidate design specifications for each aspect of the performance definition model on the display unit of the user terminal 12. For example, the setting unit 144 displays candidate design specifications S, as shown in Figure 7 or Figure 8, on the display unit of the user terminal 12.

[0063] In step S108, the setting unit 144 of the design support device 14 receives the user's selection result for design specification candidates.

[0064] In step S110, the setting unit 144 of the design support device 14 determines the design specification candidates received in step S108 as the design specifications for the building model.

[0065] Once the external specifications of the building under design are determined, it becomes possible to perform various energy and thermal load calculations based on the external specifications and each performance definition model. Each aspect of each performance definition model is assigned a performance value, and by referring to these performance values ​​(e.g., thermal insulation performance), the external specifications, and various other information (e.g., the direction of direct sunlight (whether the building faces east or west)), it becomes possible to perform various energy and thermal load calculations.

[0066] When the design support device 14 receives a signal instructing it to perform various energy calculations and thermal load calculations, it executes the processing routine shown in Figure 12.

[0067] In step S200, the calculation unit 146 of the design support device 14 acquires the external specifications of the building to be designed, as set above.

[0068] In step S202, the calculation unit 146 of the design support device 14 acquires the various performance definition models generated above.

[0069] In step S204, the calculation unit 146 of the design support device 14 generates an integrated model for calculating the energy or heat load related to the building under design by integrating the external specifications, which are the external design specifications of the building under design, and the opening model, first interior wall model, second interior wall model, and exterior wall model, which are performance definition models.

[0070] In step S206, the calculation unit 146 of the design support device 14 calculates the energy or heat load related to the building under design based on the integrated model generated in step S204, according to a known calculation method.

[0071] In step S208, the calculation unit 146 of the design support device 14 outputs the calculation results obtained in step S206.

[0072] Thus, once the performance definition model and external specifications are determined, various energy and thermal load calculations for the building under design become possible, allowing energy and thermal load calculations to be performed at an early stage of the design process. Furthermore, ZEB-related calculations can be performed efficiently.

[0073] As described in detail above, the design support device of this embodiment acquires a room zone model representing the arrangement of rooms within the building under design. Based on the acquired room zone model, the design support device generates a performance definition model, which is a model representing the performance of the room boundaries in the building under design and a model for defining the performance of the building under design. Based on the generated performance definition model, the design support device sets the design specifications for the building under design. Based on the generated performance definition model and the set design specifications for the building under design, the design support device calculates the energy or heat load associated with the building under design. This makes it possible to efficiently calculate the energy or heat load associated with the building under design.

[0074] Furthermore, the building model representing the building under design, the room zone model, and the performance definition model are all linked to each other, and if the building model and room zone model are updated in each phase of the design work, the performance definition model may be generated for each of those phases.

[0075] It should be noted that the present invention is not limited to the embodiments described above, and various modifications and applications are possible without departing from the spirit of the invention.

[0076] For example, the above embodiment describes a case where the user selects a formal design specification from design specification candidates based on performance values ​​attached to each face of the performance definition model, but it is not limited to this. The formal design specification may be automatically set based on the performance values ​​attached to each face of the performance definition model. For example, the performance values ​​attached to each face of the performance definition model may be input to a machine learning model, and the design specification information output from the machine learning model may be set as the formal design specification.

[0077] Furthermore, although the above describes a configuration in which the program is pre-stored (installed) in a storage unit (not shown), the program can also be provided in a form recorded on any of the recording media such as a CD-ROM, DVD-ROM, or microSD card.

[0078] (Note) The following is an addendum regarding the nature of this disclosure.

[0079] (Note 1) An acquisition unit that acquires a room zone model representing the layout of rooms within the building under design, A generation unit generates a performance definition model, which is a model representing the performance of the room boundaries in the building under design and a model for defining the performance of the building under design, based on the room zone model acquired by the acquisition unit.
