Description

Technical Field

[0001] This invention relates to the field of building performance analysis and adjustment technology, specifically to an integrated building performance analysis and optimization design platform system. Background Technology

[0002] With the deepening of the global sustainable development strategy and the transformation of the construction industry towards high quality and low energy consumption, building performance is no longer limited to the traditional scope of structural safety, but has expanded to a comprehensive indicator system of multiple dimensions such as energy efficiency, environmental comfort, ecological protection, and operating costs. Under the policy guidance of the "dual carbon" goal, new buildings need to meet strict energy-saving standards, and the renovation of existing buildings also faces the urgent need to improve energy efficiency and reduce carbon emissions. This has made building performance analysis change from an optional option in the design process to a mandatory option.

[0003] Common optimization design platform systems lack a quantitative correlation between building design parameters and "resistance to extreme weather" when in use, relying mainly on the designer's subjective experience rather than data support. Due to the lack of data-driven design methods, "safety performance" and "usability" are separated and isolated in the design process. At the same time, the design process is mostly a linear process of "optimize first, then verify" rather than a closed-loop design, which ultimately makes it impossible to guarantee the safety of the optimized solution. To address this, we propose an integrated building performance analysis and optimization design platform system. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated building performance analysis and optimization design platform system.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated building performance analysis and optimization design platform system, the design platform system comprising:

[0006] The building form performance acquisition module collects data on different extreme weather conditions faced by buildings, and obtains the performance of different building shapes and basic material arrangements under different extreme weather conditions, and generates a performance comparison table.

[0007] The building performance analysis module collects the original building's layout information and the corresponding basic material stacking method information, and analyzes the original building's performance index according to the performance comparison table. At the same time, it establishes interrelated analysis units: the daylighting analysis unit is used to analyze the changes in the building's external solar radiation time to provide basic data for brightness analysis. The brightness analysis unit calculates the indoor brightness distribution based on the daylighting analysis results, combined with the building's internal spatial layout and material optical properties.

[0008] The layout optimization module is used to optimize and adjust the building layout and the way basic materials are stacked in the original building, so as to obtain an optimized building.

[0009] The building impact simulation module calls the STAAD.Pro structural analysis software through the API interface, converts the building model data output by the layout optimization module into a structural model that STAAD.Pro can recognize, simulates the building response under different extreme weather intensities, and feeds back the simulation results (including stress distribution, displacement deformation, safety factor, etc.) to the layout optimization module for the next round of optimization decisions.

[0010] As a further aspect of the present invention: when the performance comparison table is obtained, corresponding performance values ​​are generated for different building shapes and the layout of basic materials according to the intensity of different extreme weather, and these values ​​are then labeled.

[0011] As a further aspect of the present invention: the lighting analysis unit is used to analyze the time changes of direct sunlight exposure on the original building in different seasons and on different dates, and to establish two time change tables;

[0012] The brightness analysis unit is used to analyze the changes in indoor brightness values ​​of the original building under different seasons.

[0013] As a further aspect of the present invention: the two time variation tables are respectively:

[0014] The first type of time variation table shows the time variation from when the sun just rises to when the sun has completely set;

[0015] The second type of time variation table shows the time from when the sun is just rising and directly shines on the building to when the sun can no longer directly shine on the building.

[0016] As a further aspect of the present invention: when analyzing the changes in indoor brightness, lux is used as the unit for the numerical change in indoor brightness, and it is plotted as a brightness numerical change graph.

[0017] Simultaneously, the times of sunrise and sunset are marked on the brightness value change graph.

[0018] As a further aspect of the present invention: when optimizing the original building, the layout optimization module extracts the stacking method of the basic materials to obtain the original stacking method;

[0019] Analyze the performance ranking of the original stacking method in the performance comparison table, then retrieve stacking methods with higher performance rankings that are interchangeable with the original stacking method in terms of construction technology, and obtain the optimized stacking methods. The number of optimized stacking methods is then determined. 1.

[0020] As a further aspect of the present invention: when the number of searches for the optimized stacking method is zero, the funds required for the basic materials in the original stacking method are analyzed to obtain the funds for the original basic materials. ;

[0021] Then analyze the funding for the original basic materials. The stacking method with costs within 120% of the original cost is used as an optimized stacking method, where the cost is based on the original basic material funds. Basic materials and funds for optimizing the stacking method of retrieval ;

[0022] The optimized stacking methods will be sorted according to the performance comparison table.

[0023] As a further aspect of the present invention: after obtaining the optimized stacking method in the layout optimization module, the performance advantages and disadvantages of different optimized stacking methods are analyzed, and the corresponding stacking method is retrieved based on the disadvantages of different optimized stacking methods to obtain the hierarchical stacking method.

[0024] An optimized stacking method is used to stack buildings to obtain a single-story building, and the thickness of the single-story building is analyzed. Then, by stacking layers, another layer of reinforced building is added on both sides of the first-floor building, with the thickness of the reinforced building being... ;

[0025] At the same time, the thickness of the building will be increased according to By varying the thickness of reinforced buildings, reinforced stacked buildings can be obtained.

[0026] As a further aspect of the present invention: the building impact simulation module will extract the reinforced building and simulate different intensities of typhoons from level 5 to level 12 around the reinforced building to obtain the performance values ​​of the reinforced building under different extreme weather conditions, and display them to the user.

[0027] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0028] 1. This invention constructs a performance comparison table of extreme weather, building shape, foundation material layout, and performance through a building form performance acquisition module, realizing a strong correlation between design parameters and extreme weather resistance performance. Through comprehensive analysis and specialized unit design, it achieves coordinated evaluation of safety performance and functionality. Through the linkage of layout optimization module and building impact simulation module, it constructs a closed loop of optimization-simulation-re-optimization, fundamentally reducing building safety risks under extreme weather. Through data-driven, modular, and closed-loop technical logic, it upgrades extreme weather adaptability from an additional consideration in traditional building design to a core driving factor.

[0029] 2. This invention solves the problems of vague evaluation and poor adaptability caused by traditional performance descriptions without intensity differentiation by marking the corresponding performance values ​​of building shape and material layout according to extreme weather intensity. By distinguishing between two types of tables, namely the full solar cycle time and the direct sunlight time inside the building, it solves the problem that traditional daylighting analysis only focuses on the duration of building illumination but ignores the degree of matching with the natural solar cycle, thus realizing a panoramic evaluation of building daylighting performance.

[0030] 3. This invention achieves the core value of accurately matching performance requirements and reducing ineffective decisions through a design that combines performance ranking retrieval with single optimization scheme locking. Through a dual retrieval mechanism of performance priority and cost compensation, it achieves a dynamic balance between performance and cost. Attached Figure Description

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0033] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Example 1:

[0035] This invention provides an integrated building performance analysis and optimization design platform system. In the core business district of a city where extreme weather occurs frequently, a super high-rise office building is under design. The area is constantly exposed to extreme weather such as summer typhoons, winter blizzards and heavy rainfall. Moreover, the surrounding buildings are dense, which places extremely high demands on the office building's wind resistance, snow load resistance, drainage performance, and indoor lighting, ventilation and comfort.

[0036] Therefore, in order to effectively solve the above problems, this application proposes an integrated building performance analysis and optimization design platform system, as shown in the attached drawings of the specification. Figure 1 As shown, the design platform system includes:

[0037] The building form performance acquisition module constructs a performance comparison table in the following ways: it collects data on different extreme weather types and intensities faced by buildings, and based on historical meteorological data, structural mechanics models and material performance databases, it establishes performance evaluation models for different building shapes and basic material layouts under corresponding extreme weather conditions, thereby generating a performance comparison table that includes building shape, material layout, extreme weather intensity and performance values.

[0038] The building performance analysis module collects the original building's layout information and the corresponding basic material stacking method information, and analyzes the original building's performance index according to the performance comparison table. At the same time, it establishes interrelated analysis units: the daylighting analysis unit is used to analyze the changes in the building's external solar radiation time to provide basic data for brightness analysis. The brightness analysis unit calculates the indoor brightness distribution based on the daylighting analysis results, combined with the building's internal spatial layout and material optical properties.

[0039] The layout optimization module is used to optimize and adjust the building layout and the way basic materials are stacked in the original building, so as to obtain an optimized building.

[0041] Simulate buildings and apply different natural weather conditions near the simulated buildings, including but not limited to earthquakes, tsunamis, typhoons, etc.

[0042] STAAD.Pro can perform static, dynamic, nonlinear, and wind-resistant design analyses of structures, supporting various structural types, including bridges, buildings, and towers. It can help engineers assess the safety and stability of buildings under extreme weather conditions such as strong winds.

[0043] Basic materials refer to materials such as bricks used in the construction process;

[0044] Specifically, data is collected on different extreme weather conditions faced by the building, and the performance of different building shapes and basic material arrangements under different extreme weather conditions is obtained. The layout information of the original building and the stacking information of the corresponding basic materials are collected, and the performance index of the original building is analyzed according to the performance comparison table. At the same time, interrelated analysis units are established: the daylighting analysis unit is used to analyze the changes in the solar radiation time outside the building to provide basic data for brightness analysis. Based on the daylighting analysis results, the brightness analysis unit calculates the indoor brightness distribution by combining the internal spatial layout of the building and the optical properties of the materials. The building layout and the stacking method of the basic materials in the original building are optimized and adjusted, and the building is subjected to impact simulation of different extreme weather intensities.

[0045] Example 2:

[0046] When the performance comparison table is obtained, corresponding performance values ​​are generated for different building shapes and the layout of basic materials based on the intensity of different extreme weather events, and these values ​​are then labeled.

[0048] The brightness analysis unit is used to analyze the changes in indoor brightness values ​​of the original building under different seasons.

[0049] The two time variation tables are as follows:

[0050] The first type of time variation table shows the time variation from when the sun just rises to when the sun has completely set;

[0051] The second type of time variation table shows the time when the sun is directly shining inside the building from the time when the sun can no longer directly shine inside the building.

[0052] When analyzing changes in indoor brightness, lux is used as the unit for the numerical change in indoor brightness, and the change is plotted as a brightness value change graph.

[0053] Simultaneously, the times of sunrise and sunset are marked in the brightness value change graph.

[0054] Performance values, such as if a building can withstand a Category 10 typhoon, then the building's performance value in a typhoon is 10.

[0055] The time change table includes two types of time change line graphs: the first is the time change graph when the sun rises, and the second is the time change graph when the sun sets completely.

[0056] Specifically, based on the intensity of different extreme weather events, corresponding performance values ​​are generated for different building shapes and the layout of basic materials. The changes in direct sunlight exposure of the original building during different seasons and dates are analyzed, and two time variation tables are established. The brightness analysis unit is used to analyze the changes in indoor brightness values ​​of the original building under different seasons. The first time variation table is the change from sunrise to sunset, and the second time variation table is the change from the time when the sun shines directly on the building during sunrise to the time when the sun can no longer directly shine on the building. Using lux as the unit for indoor brightness value changes, a brightness value change graph is plotted, and the times of sunrise and sunset are simultaneously marked on the brightness value change graph.
