The performance evaluation system is configured to evaluate (verify) the performance of a building, and performs performance evaluation for each of a plurality of evaluation indexes. The plurality of evaluation indexes are classified into a first evaluation index group and a second evaluation index group. The first evaluation index group may include, for example, the energy consumption performance of a building, and may also include the CO2 emissions and CO2 storage capacity of the building. The second evaluation index group may include, for example, the evacuation safety performance of a building, the fire resistance performance, and the quasi-fire resistance performance of a building. Fire resistance performance is the performance required to prevent collapse and the spread of a fire even if a normal fire occurs until the fire is extinguished. Quasi-fire resistance performance is the performance required to prevent the spread of a normal fire.

[0009] <Outline of the performance evaluation system> 1, the performance evaluation system 10 includes one or more devices connected via a network: a management device 20, a performance evaluation device 30, and a setting device 40. The management device 20, the performance evaluation device 30, and the setting device 40 each include one or more computers (information processing devices) 100.

[0010] <Hardware configuration> 2, the computer 100 includes a communication device 101, an input device 102, a display device 103, a storage device 104, and a processor 105. Note that this hardware configuration is an example, and it can also be realized by other hardware.

[0014] Processor 105 is not limited to a processor that performs all of its processing using software. For example, processor 105 may include a dedicated hardware circuit (e.g., an application-specific integrated circuit (ASIC)) that performs hardware processing for at least some of the processing it performs. That is, processor 105 may be configured with the following:

[0015] [1] One or more processors operating according to a computer program (software). [2] One or more dedicated hardware circuits that perform at least some of the various processes [3] Circuits containing combinations of these The processor 105 includes a CPU and memory, such as RAM and ROM, that stores program code or instructions configured to cause the CPU to perform processes. Memory, or computer-readable media, includes any available media that can be accessed by a general-purpose or special-purpose computer.

[0016] <System configuration> (Management device) 1, the management device 20 is a computer system that manages a BIM model 22. The management device 20 includes a model storage unit 21 that stores the BIM model 22. The management device 20 manages the BIM model 22 by having a processor 105 execute a BIM application.

[0017] The BIM model 22 is three-dimensional data of a building, and includes architectural structure data 23 of the building and equipment data 24 of the building. The BIM model 22 includes a three-dimensional model of the building constructed in a virtual space. The three-dimensional model of the building includes components such as columns, beams, and walls, and spaces such as rooms formed by these components. The three-dimensional model of the building also includes equipment installed in the rooms. Data related to the components and rooms is included in the architectural structure data 23. Data related to the equipment is included in the equipment data 24.

[0018] The architectural structure data 23 is, for example, data relating to the components and spaces that make up a building, and includes shape data and attribute data. The architectural structure data 23 includes, for example, architectural data 23A and structural data 23B. The architectural data 23A includes, for example, building data relating to the name, use, and location of a building. The architectural data 23A includes, for example, room data relating to room specifications, such as ID number, room name, room use, room area, floor height, and ceiling height. The structural data 23B includes, for example, component data relating to the components of a building, such as columns, beams, and exterior walls.

Each of the data 24A to 24D includes, as data related to the target equipment, for example, ID number, name, specifications, location, number of units, system, and control method.

[0020] (Performance evaluation device) The performance evaluation device 30 is a computer system that evaluates (verifies) the performance of a building. For example, the performance evaluation device 30 evaluates the performance of a building to be evaluated for each of a plurality of evaluation indicators. The performance evaluation device 30 evaluates the performance of a building by having the processor 105 execute a performance evaluation program. The performance evaluation program is stored in the storage device 104 as one of the programs 104A. The performance evaluation device 30 has an information storage unit 31, a data extraction unit 32, a data generation unit 33, a performance calculation unit 34, and an output unit 35.

[0021] The information storage unit 31 stores first conversion information 311. The first conversion information 311 is, for example, a conversion table for converting a "room name" included in the room data of the building data 23A into a "room use" under standard room use conditions. The "room name" and "room use" set in the room data of the BIM model 22 may not match the "room use" under the standard room use conditions. Therefore, the information storage unit 31 holds the first conversion information 311 for converting the "room name" into a "room use" under the standard room use conditions. The standard room use conditions are the room use conditions assumed when calculating energy consumption performance, such as the air conditioning set temperature, set humidity, lighting heat generation reference value, etc.

[0022] As shown in FIG. 3, the type of "room use" in the standard room use conditions is determined according to the type of "building use." For example, when the "building use" is "office, etc.", 19 types of "room use" are determined, including "office," "corridor," and "lobby." In the first conversion information 311, one type of "room use" is associated with one or more types of "room name." As an example, the room use "office" is associated with room names such as "office," "chairman's office," and "president's office." By referencing the first conversion information 311 based on the "building use" and "room name," the "room use" in the standard room use conditions can be identified.

[0023] As shown in FIG. 1, the information storage unit 31 stores second conversion information 312. For example, the second conversion information 312 is a conversion table for converting "room use" in the standard room use conditions into "room type." The "room name" and "room use" set in the room data of the BIM model 22, as well as the "room use" converted using the first conversion information 311, may not match the "room type" defined in Ministry of Construction Notification No. 1433. Therefore, the information storage unit 31 holds the second conversion information 312 for converting "room use (room name)" into "room type."

[0024] As shown in FIG. 4, in the second conversion information 312, one or more types of "room use (room name)" are associated with one "room type." As an example, the room type "office or similar" is associated with "office room," "central monitoring room," and "staff room." By referring to the second conversion information 312 based on the "room use (room name)," the "room type" can be identified. The "room use" in the standard room use conditions is an example of a first room use, and the "room type" is an example of a second room use.

[0025] 1, the information storage unit 31 stores the energy consumption unit information 313. For example, the energy consumption unit information 313 includes one or more energy consumption units for each of a plurality of evaluation indexes. For example, the energy consumption unit information 313 is an energy consumption unit for "room use" and includes an energy consumption unit for the room specifications described below.

[0026] When the evaluation index is energy consumption performance, for example, the basic unit for indoor use is "standard primary energy consumption per unit floor area (unit: MJ / (m 2 When the evaluation index is evacuation safety performance, fire resistance performance, and semi-fire resistance performance, for example, the basic unit for room use is "calorific value q per square meter of the loaded combustible material in the room." l (unit: MJ / m 2 )" The calorific value q l is determined in advance according to the "room type" obtained by converting the "room use" using the second conversion information 312 (see FIG. 5).

[0027] 1, the data extraction unit 32 extracts various data related to room specifications from the BIM model 22 of the management device 20. The data extraction unit 32 is realized by the processor 105 executing an extraction program. The data extraction unit 32 extracts various data indicating conditions related to the spaces (rooms) and equipment of the building from the BIM model 22.

[0028] The data extraction unit 32 extracts, for example, data required for calculating the energy consumption performance of a building from the BIM model 22. The data extraction unit 32 extracts, for example, data required for calculating the evacuation safety performance, fire resistance performance, and quasi-fire resistance performance of a building from the BIM model 22. The data extraction unit 32 acquires, for example, room data from the BIM model 22. The room data specifies, for example, "room specifications" including "room name."

[0029] The data generation unit 33 generates calculation basis data required for the performance evaluation program based on the data extracted by the data extraction unit 32. The data generation unit 33 is realized by the processor 105 executing the data generation program. The calculation basis data is data that specifies, for each room, the calculation conditions required for the performance evaluation program to calculate the performance evaluation results. The calculation basis data may be in any format, but may be, for example, a CSV file. The data generation unit 33 is configured to convert the "room name" into "room use" using first conversion information 311. The data generation unit 33 is configured to convert the "room use" into "room type" using second conversion information 312.

[0030] A specific example of the calculation base data will be described. 5, the data generation unit 33 generates, for example, calculation basis data 351 necessary for the energy consumption performance evaluation program. The calculation basis data 351 includes, for example, for each room, data such as floor, room name, building use, room use, room area, floor height, ceiling height, selection of four types of rooms to be calculated, and model building data.

[0031] The data generation unit 33 inputs the "floor," "room name," "room area," "floor height," and "ceiling height" extracted by the data extraction unit 32 as "floor," "room name," "room area," "floor height," and "ceiling height," respectively, in the calculation basis data 351. The data generation unit 33 inputs the "use" of the building extracted by the data extraction unit 32 as "building use" in the calculation basis data 351.

[0032] The data generation unit 33 identifies the "room use" by referring to the first conversion information 311 based on the "building use" and "room name" of the building extracted by the data extraction unit 32, and inputs it as the "room use" in the calculation basis data 351. For example, when the "building use" is "office, etc." and the "room name" is "windbreak room," the data generation unit 33 identifies "corridor" as the "room use" and inputs "corridor" as the "room use" in the calculation basis data 351.

[0033] The data generation unit 33 uses predetermined conversion information based on the "building use" and "room use" to select one of four types of rooms to be calculated (rooms to be calculated for air conditioning, ventilation, lighting, and hot water supply), and inputs data indicating the selection into one of the four types of rooms to be calculated in the calculation base data 351.

[0034] As shown in Fig. 6, the data generating unit 33 generates calculation basis data 352 necessary for, for example, a fire resistance performance evaluation program. The fire resistance performance evaluation program may include, for example, a calculation program for fire duration and a calculation program for fire retention fire resistance time. The calculation basis data 352 may include, for example, for each room, building use, room name, room use, room type, heat generation amount q l The data includes the surface area Af of each part for each type of interior building material in the room, and the heating perimeter Hs of the component.

[0035] The data generation unit 33 inputs the "room name," "floor area," "type of interior building material," "wall center line," and "ceiling height" extracted by the data extraction unit 32 as "room name," "floor area," "type of interior building material," "wall center line," and "ceiling height," respectively, in the calculation basis data 352. The data generation unit 33 inputs the "use" of the building extracted by the data extraction unit 32 as "building use" in the calculation basis data 352. The data generation unit 33 inputs the "steel material" and "wall" extracted by the data extraction unit 32 as the data for "steel material" and "wall," respectively, in the calculation basis data 352.

[0036] The data generation unit 33 identifies the "room use" by referring to the first conversion information 311 based on the "building use" and "room name" of the building extracted by the data extraction unit 32, and inputs it as the "room use" in the calculation basis data 352. The data generation unit 33 identifies the "room type" by referring to the second conversion information 312 based on the "room use" converted using the first conversion information 311, and inputs it as the "room type" in the calculation basis data 352.

[0037] The data generating unit 33 refers to the unit energy consumption information 313 based on the “room type” converted using the second conversion information 312 to generate the “heat generation amount q l" and "calorific value q" in calculation basic data 352 l "

[0038] The data generation unit 33 identifies the "surface area Af" based on the dimensions included in the "wall center" extracted by the data extraction unit 32, the "ceiling height", and a predetermined conversion formula, and inputs it as the "surface area Af" of the calculation basis data 352.

[0039] The data generation unit 33 identifies the heated perimeter Hs of the member based on the dimensions of the steel material included in the "steel material" extracted by the data extraction unit 32 (e.g., thickness H, width B, web thickness t1, and flange thickness t2) and the conversion formula, and inputs this as the "heated perimeter Hs of the member" in the calculation basis data 352.

[0040] The performance calculation unit 34 calculates the performance of the building based on the calculation base data generated by the data generation unit 33. The performance calculation unit 34 is realized by the processor 105 executing a performance evaluation program. The performance evaluation program includes, for example, an energy consumption performance evaluation program. The performance evaluation program includes, for example, an evacuation safety performance evaluation program, a fire resistance performance evaluation program, and a quasi-fire resistance performance evaluation program. The performance calculation unit 34 is configured to calculate the performance evaluation result of each room for each of a plurality of evaluation indexes using the basic unit and room specifications according to the room use.

[0041] The output unit 35 acquires the calculation results from the performance calculation unit 34 and outputs the calculation results of the performance calculation unit 34. The output unit 35 is realized by the processor 105 executing an output program. The performance calculation unit 34 is configured to integrate the performance evaluation results of each room and output the performance evaluation results of the building to be evaluated for each of multiple evaluation indexes.

[0042] The output unit 35 may, for example, list the calculation results for each evaluation index by the performance calculation unit 34 and display them on the display device 103. The output unit 35 may, for example, create and print a calculation report and create and print a ledger based on the calculation results for each evaluation index by the performance calculation unit 34. The calculation report may, for example, be a list of the calculation results for each of a plurality of evaluation indexes, or may be a summary of extracted parts of each evaluation index.

[0043] The output unit 35 may output calculation result data in a predetermined data format based on the calculation result for each evaluation index by the performance calculation unit 34. The output unit 35 may determine whether or not the building to be evaluated has standard performance for each evaluation index based on the calculation result by the performance calculation unit 34, and may output a predetermined warning if the building to be evaluated does not have the standard performance.

[0044] (setting device) 1, the setting device 40 performs various settings in the BIM model 22. For example, a user who performs design uses the setting device 40 to set spatial conditions of the building, thereby setting room data of the building data 23A.

[0045] The setting device 40 has a structural calculation unit 41. The structural calculation unit 41 is configured to perform structural calculations of a building. The structural calculation unit 41 is realized by the processor 105 executing a structural calculation program. The user uses the structural calculation unit 41 to set the components (columns, beams, walls, etc.) that make up the building, and to set the building structural data 23 (mainly structural data 23B) of the BIM model 22 by performing structural calculations of the building made up of those components.

[0046] The setting device 40 has an equipment setting unit 42 for considering equipment to be installed in a building. The equipment setting unit 42 is realized by, for example, having the processor 105 execute a selection support program provided by an equipment manufacturer.

[0047] The equipment setting unit 42 has, for example, a plurality of equipment setting units 42A to 42J. The air conditioning equipment setting unit 42A sets the air conditioning equipment. The ventilation equipment setting unit 42B sets the ventilation equipment. The efficiency improvement equipment setting unit 42C sets the efficiency improvement equipment. The hot water supply equipment setting unit 42D sets the hot water supply equipment. The sanitary equipment setting unit 42E sets the sanitary equipment. The renewable energy equipment setting unit 42F sets the renewable energy equipment. The substation equipment setting unit 42G sets the substation equipment. The lighting equipment setting unit 42H sets the lighting equipment. The lightning protection equipment setting unit 42I sets the lightning protection equipment. The elevator setting unit 42J sets the elevators.

[0048] 7, each of the equipment setting units 42A to 42J has a condition setting unit 421 and a selection unit 422. The condition setting unit 421 sets various conditions for equipment to be installed in the building. The selection unit 422 selects equipment to be installed in the building. The selection unit 422 selects equipment based on the room data 231 acquired from the BIM model 22 and the conditions set in the condition setting unit 421.

[0049] The selection unit 422 may acquire shape data, attribute data, etc. of the equipment from the equipment manufacturer's server 50. The selection unit 422 may select the layout, specifications, number, system, control method, etc. of the equipment based on the user's input results. The selection unit 422 sets the selection result 422A in the BIM model 22 as equipment data 241 of the equipment data 24.

[0050] Here, the air conditioning equipment setting unit 42A will be described in detail as an example. The condition setting unit 421 of the air conditioning equipment setting unit 42A sets various conditions related to air conditioning. For example, the condition setting unit 421 sets conditions for heat load calculation and conditions for controlling facility equipment such as air conditioning time. The condition setting unit 421 also sets the air conditioning system and the association of various conditions with rooms, etc.

[0051] The selection unit 422 of the air conditioning equipment setting unit 42A performs heat load calculations based on the room data 231 acquired from the BIM model 22 and the air conditioning conditions acquired from the condition setting unit 421, and selects the layout, specifications, number of units, system, control method, etc. of equipment suitable for the room conditions and control conditions. Then, the selection unit 422 sets the air conditioning equipment selection results 422A as equipment equipment data 241 (air conditioning equipment data) in the air conditioning data 24A of the BIM model 22.

[0052] The other equipment setting units 42B to 42J, like the air conditioning equipment setting unit 42A, set equipment based on the room data 231 acquired from the BIM model 22 and the conditions set in the condition setting unit 421, and set equipment data 241 in the BIM model 22.

[0053] <Performance evaluation method> The performance evaluation method will be described with reference to Fig. 8. Each step shown in Fig. 8 is executed by one or more computers 100 that constitute the performance evaluation system 10.

[0054] The structural calculation unit 41 and the equipment setting unit 42 of the setting device 40 set the BIM model 22 in the model storage unit 21 of the management device 20 (step S1). In step S1, a three-dimensional model of a building having spaces (rooms) made up of components and equipment installed in the spaces is set. The BIM model 22 includes architectural structural data 23 and equipment data 24.

[0055] The data extraction unit 32 of the performance evaluation device 30 extracts data from the BIM model 22 (step S3). In step S3, room data is extracted from the BIM model 22. That is, the data extraction unit 32 acquires room specifications from the BIM model 22. The room data extracted by the data extraction unit 32 includes "building use" and "room name." The data extraction unit 32 acquires the room name from the BIM model 22 of the building to be evaluated. Therefore, the data necessary for performance evaluation of the building can be collected efficiently and reliably.

[0056] The data generation unit 33 of the performance evaluation device 30 generates calculation basis data required for performance evaluation using the performance evaluation program based on the data extracted from the BIM model (step S5). The data generation unit 33 inputs part or all of the data extracted in step S3 into the calculation basis data.

[0057] The data generation unit 33 identifies the "room use" by referring to the first conversion information 311 based on the "building use" and "room name" extracted in step S3, and inputs the "room use" into the calculation basis data. The data generation unit 33 identifies the "room type" by referring to the second conversion information 312 based on the "room use" obtained by converting the "room name" using the first conversion information 311, and inputs the "room type" into the calculation basis data. In this way, the data generation unit 33 is configured to convert the "room name" into the "room use" using the conversion information.

[0058] The data generation unit 33 acquires the basic unit information by referring to the basic unit information 313 based on the "room use" and "room type" and inputs it into the calculation base data. Therefore, even in a situation where the data set in the BIM model 22 does not match or is insufficient with the data required for the performance evaluation program, the data required for the performance evaluation of the building can be reliably collected.

[0059] The performance calculation unit 34 of the performance evaluation device 30 inputs the calculation basis data generated in step S5 into the building performance evaluation program to calculate performance (step S7). The performance calculation unit 34 executes, for example, an energy consumption performance evaluation program, an evacuation safety performance evaluation program, a fire resistance performance evaluation program, and a quasi-fire resistance performance evaluation program. For each of a plurality of evaluation indexes, the performance calculation unit 34 calculates the performance evaluation result for each room using the basic unit information according to the "room use" and the "room specifications."

[0060] The output unit 35 of the performance evaluation device 30 outputs the performance evaluation results from step S7 (step S9). The output unit 35 is configured to integrate the performance evaluation results of each room and output the performance evaluation results of the building to be evaluated for each evaluation index. The output unit 35, for example, displays the performance evaluation results for each evaluation index on the display device 103, prints the performance evaluation results for each evaluation index, or stores the performance evaluation result data for each evaluation index in a predetermined storage unit.

[0061] The performance evaluation result is, for example, a numerical value indicating an evaluation index. The numerical value indicating the evaluation index may be the numerical value of one item or may be the numerical value of multiple items. The performance evaluation result may be, for example, the result of comparing the numerical value indicating the evaluation index with a reference value that the numerical value indicating the evaluation index should satisfy. The performance evaluation result may also include the result of determining whether the calculation base data input to the performance calculation unit 34 satisfies the data conditions required by the performance evaluation program.

[0062] <Actions and Effects of This Embodiment> The operation and effects of this embodiment will be described. (1) In this embodiment, the "room name" acquired from the BIM model 22 is converted to "room use" using conversion information, and the performance evaluation result of each room is calculated for each evaluation index based on the basic unit information corresponding to the converted "room use" and the "room specifications" acquired from the BIM model 22. Then, the performance evaluation results of each room are integrated, and the performance evaluation result of the building to be evaluated can be output. Therefore, the performance of a building can be evaluated using multiple evaluation indexes.

[0063] (2) In this embodiment, the first conversion information 311 is used to convert to "room use," and the second conversion information 312 is used to convert to "room type." Therefore, data for calculating performance evaluation results for each of a plurality of evaluation indexes can be collected efficiently and reliably.

[0064] (3) In this embodiment, the performance of the building to be evaluated can be evaluated based on multiple evaluation indices such as energy consumption performance, evacuation safety performance, fire resistance performance, and semi-fire resistance performance, etc. Therefore, appropriate measures can be taken based on the multifaceted evaluation results of the building.

[0065] (4) Users can change the design of a building based on the performance evaluation results for each of multiple evaluation indices. Users can also change the settings of equipment. In other words, by reconfiguring the building structure data 23 and equipment data 24 of the BIM model 22, it is possible to design a building that meets the required performance.

[0066] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0067] The evaluation index may include CO2 emissions and CO2 storage. When the evaluation index is CO2 emissions, the basic unit for a building component is, for example, "emissions basic unit (unit: kg-C / kWh)." When the evaluation index is CO2 storage, the basic unit for a building component is, for example, "storage basic unit (tC)." The data generation unit 33 generates basic calculation data required for calculating CO2 emissions and CO2 storage based on various data extracted from the BIM model 22 by the data extraction unit 32. The performance evaluation program includes a CO2 emissions calculation program and a CO2 storage calculation program. The performance calculation unit 34 inputs the basic calculation data into the performance evaluation program to calculate performance.
