Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0020] This application can be used in a wide variety of general-purpose or special-purpose computing device environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor devices, distributed computing environments including any of the above devices, etc.

[0021] This application provides a method for testing energy-efficient buildings based on BIM technology. The method is applied to a server, which includes an offline message list corresponding to the receiving end. The offline message list stores at least one offline message sent by the sending end to the receiving end in an offline state. The method flowchart is shown below. Figure 1 As shown, it specifically includes: S1: Obtain the initial BIM model of the target building and the geographic information of the target building to be constructed.

[0022] The initial BIM model is generated based on the basic design information of the target building.

[0023] Basic design information includes the structural parameters of the target building, the initial material parameters of the materials required to construct the target building, the envelope parameters, and the component parameters. Among them, the initial material parameters include the material type and material properties.

[0024] Specifically, this application inputs the basic design information into the pre-set iTWO software. The iTWO software then constructs an initial BIM model of the target building based on the various parameters in the input basic design information. The iTWO software is a BIM 5D (Building Information Modeling) integration platform that supports the full lifecycle management of building projects from design and construction to operation and maintenance.

[0025] After constructing the initial BIM model using iTWO software, the corresponding building construction standards for that region can be obtained based on the geographic information. It is then determined whether the building corresponding to the initial BIM model conforms to the regional building construction standards. If it does, steps S2-S6 are executed. If it does not conform to the regional building construction standards, the initial BIM model can be adjusted according to those standards until it meets them.

[0026] S2: Obtain multiple preset material combinations.

[0027] Each material combination includes environmentally friendly material parameters for multiple environmentally friendly building materials.

[0028] Each material combination includes environmental material parameters for multiple types of building materials. For example, material combination 1 includes recycled steel, engineered wood, and vacuum glass, while material combination 2 includes recycled steel, bamboo, and Low-E glass. Although the required material types are the same in both material combinations, the environmental material parameters of the materials differ.

[0029] S3: Based on the parameters of each environmentally friendly material contained in each material combination, update the initial BIM model to obtain the test BIM model corresponding to each material combination.

[0030] Specifically, updating the initial BIM model involves inputting basic design information into the iTWO software to update the BIM model built using the iTWO software.

[0031] Since the basic design information includes initial material parameters, updating the BIM model based on the environmentally friendly material parameters included in the material combination can specifically involve updating the initial material parameters in the basic design information to the environmentally friendly material parameters in the material combination. However, due to differences in chemical properties, physical characteristics, or construction processes, some environmentally friendly building materials cannot be used in direct contact together (i.e., there are incompatible materials). Otherwise, it may lead to performance degradation, safety hazards, or environmental pollution. However, in order to use them normally, the application of incompatible materials can be achieved through isolation.

[0032] Therefore, refer to Figure 2 In this application, based on the parameters of each environmentally friendly material included in each material combination, the initial BIM model is updated to obtain the test BIM model corresponding to each material combination, including: S31: Detect whether there are incompatible materials in each material combination.

[0033] For each material combination, it is checked whether there are two or more environmentally friendly building materials that cannot be directly contacted among all the environmentally friendly building materials to which the material combination belongs. If there are two or more environmentally friendly building materials that cannot be directly contacted, then the building materials are incompatible materials. If there are incompatible materials in any material combination, then proceed to S32; if there are no incompatible materials in any material combination, then proceed to S34.

[0034] S32: Obtain the preset partition parameters corresponding to the incompatible materials.

[0035] The partition parameters are the material parameters of the isolation material, which can be acid-resistant, alkali-resistant, or waterproof coatings, etc. The partition parameters can be set according to the material characteristics of incompatible materials.

[0036] Optionally, the isolation parameters include a material marker used to mark incompatible materials that need to be isolated.

[0037] S33: Add partition parameters in iTWO software, update the initial material parameters in the basic design information to the environmentally friendly material parameters in the material combination, and obtain the test BIM model corresponding to the material combination.

[0038] Input the partition parameters into the iTWO software, then update the initial material parameters in the basic design of Western Sydney to environmentally friendly material parameters. The iTWO software will automatically update the initial BIM model to the test BIM model corresponding to the material combination based on the updated parameters.

[0039] S34: In iTWO software, update the initial material parameters in the basic design information to the environmentally friendly material parameters in the material combination, and obtain the test BIM model corresponding to the material combination.

[0040] Understandably, if no partitions are needed between materials, the initial material parameters in the basic design information can be updated to environmentally friendly material parameters so that the initial BIM model can be updated to a test BIM model using iTWO software.

[0041] S4: Obtain the first and second environmental parameters related to geographic information.

[0042] The first environmental parameter is the environmental parameter under daily life conditions, and the second environmental parameter is the environmental parameter under natural disaster conditions.

[0043] Environmental parameters in everyday environments include temperature, humidity, daylight hours, and wind direction in different seasons. Environmental parameters in natural disaster environments include parameters specific to different types of natural disasters, such as earthquake magnitude and ground shaking in an earthquake environment, and wind speed and rainfall in a typhoon environment.

[0044] S5: Based on the first and second environmental parameters, perform a quality assessment on each test BIM model.

[0045] By using first and second environmental parameters, each test BIM model is simulated to reflect performance changes in a real-world environment, and the quality of the test BIM model is evaluated based on these performance changes.

[0046] For details, please refer to Figure 3 In this application, the quality assessment of each test BIM model is performed based on the first environmental parameter and the second environmental parameter. The specific implementation steps are as follows: S51: Based on geographic information, obtain disaster information on various natural disasters that occurred in the region to which the geographic information belongs within a preset historical time period.

[0047] The disaster information includes the time of occurrence, frequency of occurrence, disaster level, and degree of damage.

[0048] S52: Based on disaster information, set the first weight corresponding to the first environmental parameter and the second weight corresponding to the second environmental parameter.

[0049] The second weight is less than the first weight.

[0050] It is understandable that natural disasters are low-probability events, and buildings are usually in normal daily life environments. Therefore, the first weight corresponding to the first environmental parameter that belongs to the daily life environment is greater than the second weight corresponding to the second environmental parameter that is related to natural disasters.

[0051] The weight of the second weight is related to the disaster information it corresponds to. The closer the time of the most recent disaster is to the current time, the greater the weight. The higher the frequency of occurrence, the greater the weight. The higher the disaster level, the greater the weight. The greater the degree of damage, the greater the weight.

[0052] S53: Generate an environmental change system corresponding to the region based on the first environmental parameter, the first weight, the second environmental parameter, and the second weight.

[0053] Among them, the environmental change system is used to simulate the environmental changes between daily life environment and natural disaster environment in real-world conditions.

[0054] Specifically, based on the first environmental parameter, the first weight, the second environmental parameter, and the second weight, an environmental change system corresponding to the region is generated, including: An initial environmental system corresponding to a region is constructed using a pre-defined digital twin system; the first environmental parameter, the first weight, the second environmental parameter, and the second weight are imported into the initial environmental system to obtain the environmental change system corresponding to the region.

[0055] By inputting a first environmental parameter, a first weight, a second environmental parameter, and a second weight into the digital twin system, a virtual mapping of the natural environment can be achieved. At the same time, the system can also simulate the changing process of the natural environment based on the set parameters.

[0056] S54: Import each test BIM model into the environmental change system to record the change information of each test BIM model in the environmental change system.

[0057] Specifically, the method for recording the change information of each test BIM model in the environmental change system is as follows: apply the preset finite element analysis method to analyze the performance parameters of the test BIM model after each environmental change in the environmental change system; based on the performance parameters after each environmental change, obtain the change information of the test BIM model in the environmental change system.

[0058] The performance parameters after each environmental change refer to the changes in parameters such as stress, strain, and deformation of the building corresponding to the test BIM model after each environmental change. For example, after inputting the BIM model into the environmental change system, the system simulates the switching of normal natural environments such as wind, rain, day and night, as well as the switching from normal environments to natural disaster environments (such as simulating normal weather switching to typhoon weather). After each environmental switch, the performance parameters of the building corresponding to the BIM model are obtained in real time to determine the impact on the building after each environmental change.

[0059] This change information includes performance parameters after each environmental change, the building life and depreciation of the building corresponding to the BIM model obtained based on the performance parameters, etc.

[0060] S55: Based on the change information of each test BIM model, perform a quality assessment on each test BIM model.

[0061] Understandably, quality assessment of the test BIM model is to determine whether the target building would meet the expected building standards if constructed according to the test BIM model, such as whether the building could maintain normal building standards after multiple natural disasters.

[0062] S6: Based on the evaluation results of each test BIM model, select one material combination from the various material combinations as the target material combination for constructing the target building.

[0063] Optionally, based on the evaluation results, the optimal test BIM model is determined, and the material combination related to the optimal BIM model is selected from the various material combinations as the target material combination. The environmentally friendly building materials corresponding to the target material combination can be used as the building materials for the final construction of the target building.

[0064] In one alternative implementation, the specific method for selecting a material combination from each material combination as the target material combination for constructing the target building based on the evaluation results of each test BIM model can be as follows: select a material combination whose evaluation results meet the target evaluation conditions as a pre-selected material combination; obtain the cost information corresponding to each pre-selected material combination; and select a material combination from each pre-selected material combination as the target material combination for constructing the target building based on the cost information.

[0065] The evaluation results are used to characterize whether the building corresponding to the test BIM model meets building standards. If multiple material combinations exist for constructing the target building and all meet the building standards, the material combination with the lower cost can be selected as the target material by considering the cost information of each material combination. This not only ensures that the constructed target building meets the standards but also saves money.

[0066] Visualization can be used in the processes of building the initial BIM model, updating the initial BIM model to a test BIM model, and simulating the performance of the BIM model in a natural environment within a digital twin system. Similarly, when obtaining change information about the test BIM model, the changes in the test BIM model can be displayed using cloud maps or similar methods, allowing for a more intuitive observation of the impact of environmental changes on the building.

[0067] In the method provided in this application embodiment, basic design information is input into the iTWO software to generate an initial BIM model of the target building to be constructed. After obtaining multiple material combinations, the initial BIM model is generated in the iTWO software based on the environmental protection material parameters of each material combination to obtain a test BIM model corresponding to each material combination. At the same time, a digital motion simulation system is applied to simulate the impact of switching between normal and natural disaster environments on the building, thereby determining whether the building constructed based on each test BIM model can meet building standards. Then, among the material combinations corresponding to the test BIM models that meet the building standards, one material combination is selected as the material combination for constructing the target building.

[0068] By applying the method provided in this application, a building to be constructed can be simulated using a BIM model, and the performance of the BIM model can be tested by simulating changes in the natural environment, so as to ensure that environmentally friendly materials can be selected for the construction of the target building, while ensuring that the target building meets building standards.
