[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script.

[0020] like Figure 1 As shown, a BIM-based prefabricated station building design optimization method provided by an embodiment of the present invention includes: S100, acquiring station building design data, wherein the station building design data includes components, and performing three-dimensional modeling according to the station building design data.

[0021] In this step, the station building design data is obtained. The station building design data includes components. The component data includes detailed information of various station building elements such as walls, beams, columns, floor slabs, doors, windows, stairs, etc., such as the size, material and bearing capacity of columns, the thickness, material and insulation performance of walls, and may also include relevant construction standards, station building regulations, structural specifications and fire safety requirements; Three-dimensional modeling is performed based on the station building design data. Preliminary modeling is performed based on the floor plan, elevation, and section drawings in the station building design data to establish the basic framework of the station building. The basic structure of the station building is formed by positioning and combining components in three-dimensional space. For example, the size and position of columns, beams, and floor slabs are input to create the frame structure of the station building. Three-dimensional modeling provides full life cycle support for station building design, construction, and later operations. The three-dimensional model provides more intuitive and accurate station building information, which can effectively reduce errors, improve collaborative efficiency, optimize design quality, and ultimately improve the feasibility and sustainability of the station building project.

[0022] S200, obtaining station building component library data, obtaining standardized components through the station building component library data, modular design is composed of standardized components, component size, component position and component connection method of the standardized components are determined through modular design, and the modular design is visualized.

[0023] In this step, the station building component library data is obtained. The component library data contains various specifications, materials, performance and other information of the station building components. By obtaining and integrating the station building component library data, the design team can perform modular design based on standardized components. Modular design is to decompose the station building into several prefabricated modules, each module contains multiple standardized components, and is assembled, transported and constructed in a predetermined manner; The size, location and connection method of standardized components are determined through modular design. The size of each component is determined according to the design requirements, functional requirements and construction standards of the project. The layout of standardized components must be determined according to the spatial planning of the station building design. Each component in the modular design needs to be accurately connected according to the construction process. Visualizing modular design can help designers, construction workers and customers understand the design effects, construction steps and expected results more intuitively.

[0024] S300, acquisition processing link, component production is carried out according to standardized components, production results are compared with error thresholds, if it is determined that the threshold is exceeded, component production is carried out again, supply chain thresholds are compared with monitoring data, if it is determined that the threshold is exceeded, supply chain is re-planned.

[0025] In this step, the acquisition process, through BIM technology, the station building design stage will first standardize the modeling of all components to determine the size, shape, material, connection method and other parameters of the components. These components will be mass-produced in the factory and accurately manufactured according to the design drawings; In the component production process, error control is the key. The production accuracy of each component has a preset error range, which is the error threshold. The production results are compared with the error threshold. If the error of the produced component exceeds the set threshold, an alarm will be triggered to prompt the production department to re-produce the component; Compare the supply chain thresholds with the monitoring data, and track the production, transportation, inventory and delivery status of all components through the monitoring data. If the supply chain monitoring system detects that a certain link exceeds the threshold, it will be determined that the threshold is exceeded and the supply chain is re-planned. This will trigger an automated early warning, and the system will automatically re-plan the supply chain based on the current situation.

[0026] S400, obtaining energy demand based on three-dimensional modeling, obtaining energy efficiency analysis results of the current station building, comparing the energy efficiency analysis results of the current station building with the energy demand, and if the analysis result is less than the energy demand, adding renewable energy design.

[0027] In this step, energy demand is obtained based on 3D modeling. Based on the 3D model of the station building, energy analysis tools are used for simulation to obtain the energy efficiency analysis results of the current station building. Energy efficiency analysis is to simulate the energy performance of the station building through BIM. Energy efficiency analysis is a key step to ensure that the station building has lower energy consumption and higher comfort during operation. Compare the current station building energy efficiency analysis results with the energy demand. If the analysis result is less than the energy demand, then increase the renewable energy design. If the energy efficiency analysis result of the station building is lower than the energy demand of the station building, then increasing the renewable energy design becomes an effective means to improve the energy performance of the station building.

[0028] like Figure 2 As shown, as a preferred embodiment of the present invention, the steps of obtaining station building component library data, obtaining standardized components through the station building component library data, modular design is composed of standardized components, determining the component size, component position and component connection method of the standardized components through modular design, and visualizing the modular design specifically include: S201, obtaining station building component library data, wherein the station building component library data is created by BIM technology, and standardized components are obtained through the station building component library data.

[0029] In this step, the station building component library data is obtained. The station building component library data is created through BIM technology. Each component in the BIM model is not only a three-dimensional geometric figure, but also contains multiple attributes, including component type, component size and specification, material, physical properties and construction details. Component types include walls, columns, beams, floors and doors and windows, component sizes and specifications such as wall thickness, column height and diameter, beam span, materials such as reinforced concrete, steel, glass and wood, physical properties such as strength, fire resistance and thermal conductivity, construction details such as component connection method and construction process requirements; Standardized components are obtained through the station building component library data. The use of standardized components greatly reduces duplication of work and material waste in the design and construction process, and can be reused in multiple projects, ensuring uniformity of quality and controllability of construction.

[0030] S202, obtaining a modular design, wherein the modular design is to prefabricate and reuse large-scale components, and the modular design is composed of standardized components, and the component size, component position and component connection method of the standardized components are determined by the modular design.

[0031] In this step, modular design is obtained. Modular design is to design, produce and construct prefabricated, reusable large components by splitting the station building into multiple prefabricated, standardized modules or components. These modules are usually prefabricated in the factory and quickly assembled after being transported to the construction site, which can significantly improve construction efficiency and reduce the complexity and cost of on-site construction; Modular design is composed of standardized components. Modular design includes a series of optimization measures such as the selection of standardized components, the determination of component sizes, the arrangement of component locations, and the connection methods of components. BIM technology plays an important role in this process. It can help designers accurately model and visualize modular components, and optimize functionality and construction. The size, position and connection method of standardized components are determined through modular design to ensure that the modules can be assembled efficiently and safely on the construction site. According to the functional requirements and the structural requirements of the station building, the standardized size of each component is first determined, and the relative position of each component needs to be reasonably arranged. The connection method in the modular design needs to ensure the stability and safety between modules; For example, when designing a prefabricated residential project, a modular design is adopted with the goal of dividing the station building into multiple standardized modules. Each residential unit is a module, such as a bedroom or a living room, and is composed of standardized components. Standardized wall components (such as 3m×4m prefabricated reinforced concrete wall panels), standardized floor components (such as 5m×5m prefabricated reinforced concrete floor panels) and standardized door and window components (such as standardized double-glazed windows) are selected. The size of each wall panel module has been standardized, the wall panel thickness is 200mm, and the window position has been fixed. The positions of the wall modules, door and window modules and floor modules are arranged according to the predetermined functional divisions (such as bedrooms, living rooms, kitchens, etc.), and the modules are connected together with bolts using embedded steel connectors.

[0032] S203, performing visualization processing on the modular design, wherein the visualization processing is a three-dimensional model of the component, and sending the visualization processing result to the terminal.

[0033] In this step, the modular design is visualized into a three-dimensional component model. The modular station building design generated by BIM technology is converted into a visualized three-dimensional model, which is convenient for the design team, construction personnel and customers to intuitively understand, modify and optimize. Each prefabricated module is assembled and positioned according to the design requirements. The connection relationship, construction sequence, and assembly and disassembly methods between each module will be accurately displayed in three-dimensional space to simulate the real construction process.

[0034] like Figure 3 As shown, as a preferred embodiment of the present invention, the acquisition and processing link, producing components according to standardized components, comparing the production results with the error threshold, reproducing the components if it is determined to exceed the threshold, comparing the supply chain threshold with the monitoring data, and replanning the supply chain if it is determined to exceed the threshold, specifically includes: S301, obtaining processing links, the processing links include component production and supply chain, producing components according to standardized components, obtaining production results, and obtaining an error threshold, the error threshold being the maximum error allowed in the production process.

[0035] In this step, the processing links are obtained, which include component production and supply chain. Component production is a very critical step in prefabricated station buildings. The production of standardized components can be carried out by directly connecting intelligent production equipment and BIM models. The component data in the BIM model is automatically transmitted to the production system, so that the production equipment can accurately manufacture components according to these parameters and produce components according to standardized components. Get the production results and the error threshold. The error threshold refers to the maximum error range allowed during the component production process. It is formulated based on multiple factors such as design specifications, material properties, and construction requirements, and is the acceptable deviation range during the production process.

[0036] S302, comparing the production result with the error threshold, if it is determined that the threshold is exceeded, re-producing the component, and obtaining monitoring data, the monitoring data is used to monitor the supply chain, the supply chain includes material procurement, transportation and storage.

[0037] In this step, the production result is compared with the error threshold. If it is determined to exceed the threshold, the component production is repeated. For example, for a wall component, the design thickness is 200mm, and the error threshold may be set to ±1mm, that is, the actual thickness of the wall should be between 199mm and 201mm. Components exceeding this range will be judged as unqualified. Obtain monitoring data. Monitoring data is used to monitor the supply chain. Supply chain management has a huge impact on component production. Ensuring the smooth flow of raw materials, transportation, and storage can avoid production stagnation due to material shortages, delays, or damage. The supply chain includes material procurement, transportation, and storage. For example, the threshold set in the procurement link is that the material inventory is lower than the safety inventory. When a link exceeds the threshold, the supply chain management system will automatically adjust it.

[0038] For example, the material procurement department receives a warning from the supply chain monitoring system and finds that the steel bar inventory is about to fall below the safety inventory. It automatically generates a procurement instruction, notifies the purchaser to place orders in advance and adjust the supplier. At the same time, the transportation department also monitors that the transportation time of prefabricated components may be delayed due to traffic problems. By rearranging the transportation route and adding transportation vehicles, it ensures that the components arrive on time to avoid affecting the construction progress due to insufficient materials or transportation delays.

[0039] S303, obtaining a supply chain threshold, which is the minimum requirement of the production plan, and comparing the supply chain threshold with the monitoring data. If it is determined that the threshold is exceeded, the supply chain is replanned.

[0040] In this step, the supply chain threshold is obtained. The supply chain threshold is the minimum requirement of the production plan and is used to determine whether the execution of a certain link in the supply chain meets the basic requirements of the production plan. The supply chain threshold is set based on historical data, production experience, and demand forecasts. For example, the material procurement threshold refers to the minimum purchase quantity of the required raw materials, the transportation threshold is the threshold of the transportation link, which usually involves transportation time, transportation distance and transportation capacity, and the storage threshold is the minimum quantity requirement for inventory; Compare the supply chain thresholds with the monitoring data. When the monitoring data shows that a certain link in the supply chain exceeds the preset threshold, immediate measures need to be taken to replan the supply chain to avoid affecting the overall production progress.

[0041] like Figure 4 As shown, as a preferred embodiment of the present invention, the energy demand is obtained according to the three-dimensional modeling, the energy efficiency analysis result of the current station is obtained, and the energy efficiency analysis result of the current station is compared with the energy demand. If the analysis result is less than the energy demand, the step of adding renewable energy design is specifically included: S401, obtaining energy demand based on three-dimensional modeling, wherein the energy demand is the energy consumption limit of the station building.

[0042] In this step, energy demand is obtained according to 3D modeling. Based on the 3D model of the station building, energy analysis tools are used for simulation, such as EnergyPlus, to calculate the energy consumption limit of the station building under different seasons and usage conditions. The energy consumption limit is affected by four factors: heat load, lighting load, ventilation load, and equipment load. Heat load refers to the heat inflow and outflow of the station building, including heat conduction and radiation through walls, roofs, and windows, analyzing heating and cooling needs; lighting load refers to the energy demand for lighting inside the station building. It includes a combination of natural light and artificial lighting, as well as the energy efficiency of the lighting system; ventilation load refers to the energy consumed by the ventilation system of the station building; equipment load: the energy demand of the power equipment inside the station building, such as air conditioners, elevators, and computers.

[0043] S402, obtaining the energy efficiency analysis result of the current station building, wherein the energy efficiency analysis is to simulate the energy performance of the station building through BIM, and the energy performance simulation includes thermal performance, air conditioning load, lighting effect and energy consumption.

[0044] In this step, the energy efficiency analysis results of the current station building are obtained. Energy efficiency analysis is to simulate the energy performance of the station building through BIM. Energy efficiency analysis is a key step to ensure that the station building has lower energy consumption and higher comfort during operation. Energy performance simulation includes thermal performance, air conditioning load, lighting effect and energy consumption; thermal performance analysis focuses on factors such as heat conduction, heat radiation and heat convection of station buildings, and evaluates the heat load requirements of station buildings in different seasons; air conditioning load analysis focuses on calculating the air conditioning requirements of station buildings under different climatic conditions; lighting effect analysis evaluates the natural light conditions of station buildings in different seasons and times to ensure that there is enough daylight indoors, while avoiding excessive sunlight exposure that leads to reduced energy efficiency; energy consumption analysis is to calculate the total energy consumption of station buildings by comprehensively considering all energy use requirements of station buildings; Energy performance simulation of station buildings through BIM and energy efficiency analysis can help designers conduct a comprehensive station performance evaluation during the design phase, identify potential energy consumption problems in advance, and reduce energy waste through optimized design. For example, changing the facade material of the station building, optimizing the window design, adjusting the station building layout, and adopting an efficient air conditioning system can significantly improve the energy efficiency of the station building.

[0045] S403, comparing the current station building energy efficiency analysis result with the energy demand, if the analysis result is less than the energy demand, then increasing the renewable energy design.

[0046] In this step, the energy efficiency analysis results of the current station building are compared with the energy demand to evaluate whether the energy efficiency of the existing station building design can meet the predetermined energy consumption limit. If the energy efficiency analysis results of the station building are lower than the energy demand of the station building, then adding renewable energy design becomes an effective means to improve the energy performance of the station building; When the energy efficiency result of the station building obtained through energy efficiency analysis is less than the energy demand of the station building, it means that the existing design of the station building may not be able to meet the prescribed standards or targets in terms of energy consumption. The shortfall can be compensated by adding renewable energy design to enhance the energy self-sufficiency of the station building while reducing dependence on traditional energy. For example, solar photovoltaic panels can be installed on the roof to convert solar energy into electricity.

[0047] like Figure 5 As shown, an embodiment of the present invention provides a BIM-based prefabricated station building design optimization system, the system comprising: The data acquisition module 100 is used to acquire station building design data, wherein the station building design data includes components, and perform three-dimensional modeling based on the station building design data.

Three-dimensional modeling provides full life cycle support for station building design, construction, and later operations. The three-dimensional model provides more intuitive and accurate station building information, which can effectively reduce errors, improve collaborative efficiency, optimize design quality, and ultimately improve the feasibility and sustainability of the station building project.

[0049] The standardization module 200 is used to obtain the station building component library data, obtain standardized components through the station building component library data, and the modular design is composed of standardized components. The component size, component position and component connection method of the standardized components are determined through the modular design, and the modular design is visualized.

If the energy efficiency analysis result of the station building is lower than the energy demand of the station building, then increasing the renewable energy design becomes an effective means to improve the energy performance of the station building.

[0056] like Figure 6 As shown, as a preferred embodiment of the present invention, the standardization module 200 includes: The standardization unit 201 is used to obtain station building component library data, where the station building component library data is created using BIM technology, and standardized components are obtained using the station building component library data.

[0057] In this module, the standardization unit 201 obtains the station building component library data, which is created by BIM technology. Each component in the BIM model is not only a three-dimensional geometric figure, but also contains multiple attributes, including component type, component size and specification, material, physical properties and construction details. Component types include walls, columns, beams, floors and doors and windows, component sizes and specifications such as wall thickness, column height and diameter, beam span, materials such as reinforced concrete, steel, glass and wood, physical properties such as strength, fire resistance and thermal conductivity, and construction details such as component connection methods and construction process requirements; Standardized components are obtained through the station building component library data. The use of standardized components greatly reduces duplication of work and material waste in the design and construction process, and can be reused in multiple projects, ensuring uniformity of quality and controllability of construction.

[0058] The modular unit 202 is used to obtain a modular design, wherein the modular design is a prefabricated, reusable large-scale assembly, and the modular design is composed of standardized components, and the component size, component position and component connection method of the standardized components are determined by the modular design.

[0059] In this module, the modular unit 202 obtains modular design, which is to design, produce and construct prefabricated, reusable large components by splitting the station building into multiple prefabricated, standardized modules or components. These modules are usually prefabricated in the factory and quickly assembled after being transported to the construction site, which can significantly improve construction efficiency and reduce the complexity and cost of on-site construction; Modular design is composed of standardized components. Modular design includes a series of optimization measures such as the selection of standardized components, the determination of component sizes, the arrangement of component locations, and the connection methods of components. BIM technology plays an important role in this process. It can help designers accurately model and visualize modular components, and optimize functionality and construction. The size, position and connection method of standardized components are determined through modular design to ensure that the modules can be assembled efficiently and safely on the construction site. According to the functional requirements and the structural requirements of the station building, the standardized size of each component is first determined, and the relative position of each component needs to be reasonably arranged. The connection method in the modular design needs to ensure the stability and safety between modules; For example, when designing a prefabricated residential project, a modular design is adopted with the goal of dividing the station building into multiple standardized modules. Each residential unit is a module, such as a bedroom or a living room, and is composed of standardized components. Standardized wall components (such as 3m×4m prefabricated reinforced concrete wall panels), standardized floor components (such as 5m×5m prefabricated reinforced concrete floor panels) and standardized door and window components (such as standardized double-glazed windows) are selected. The size of each wall panel module has been standardized, the wall panel thickness is 200mm, and the window position has been fixed. The positions of the wall modules, door and window modules and floor modules are arranged according to the predetermined functional divisions (such as bedrooms, living rooms, kitchens, etc.), and the modules are connected together with bolts using embedded steel connectors.

[0060] The visualization unit 203 is used to perform visualization processing on the modular design, wherein the visualization processing is a three-dimensional model of the component, and sends the visualization processing result to the terminal.

[0061] In this module, the visualization unit 203 visualizes the modular design into a three-dimensional component model. The modular station building design generated by BIM technology is converted into a visualized three-dimensional model, which is convenient for the design team, construction personnel and customers to intuitively understand, modify and optimize; Each prefabricated module is assembled and positioned according to the design requirements. The connection relationship, construction sequence, and assembly and disassembly methods between each module will be accurately displayed in three-dimensional space to simulate the real construction process.

[0062] like Figure 7 As shown, as a preferred embodiment of the present invention, the processing module 300 includes: The processing unit 301 is used to obtain processing links, which include component production and supply chain, produce components according to standardized components, obtain production results, and obtain an error threshold, which is the maximum error allowed in the production process.

[0063] In this module, the processing unit 301 obtains the processing links, which include component production and supply chain. Component production is a very critical step in the prefabricated station building. The production of standardized components can be carried out by directly connecting intelligent production equipment and BIM models. The component data in the BIM model is automatically transmitted to the production system, so that the production equipment can accurately manufacture components according to these parameters and produce components according to standardized components; Get the production results and the error threshold. The error threshold refers to the maximum error range allowed during the component production process. It is formulated based on multiple factors such as design specifications, material properties, and construction requirements, and is the acceptable deviation range during the production process.

[0064] The supply chain unit 302 is used to compare the production results with the error threshold. If it is determined that the threshold is exceeded, the component production is restarted, and monitoring data is obtained. The monitoring data is used to monitor the supply chain, which includes material procurement, transportation and storage.

[0065] In this module, the supply chain unit 302 compares the production result with the error threshold. If it is determined that the threshold is exceeded, the component production is repeated. For example, for a wall component, the design thickness is 200mm, and the error threshold may be set to ±1mm, that is, the actual thickness of the wall should be between 199mm and 201mm. Components exceeding this range will be judged as unqualified. Obtain monitoring data. Monitoring data is used to monitor the supply chain. Supply chain management has a huge impact on component production. Ensuring the smooth flow of raw materials, transportation, and storage can avoid production stagnation due to material shortages, delays, or damage. The supply chain includes material procurement, transportation, and storage. For example, the threshold set in the procurement link is that the material inventory is lower than the safety inventory. When a link exceeds the threshold, the supply chain management system will automatically adjust it.

[0066] For example, the material procurement department receives a warning from the supply chain monitoring system and finds that the steel bar inventory is about to fall below the safety inventory. It automatically generates a procurement instruction, notifies the purchaser to place orders in advance and adjust the supplier. At the same time, the transportation department also monitors that the transportation time of prefabricated components may be delayed due to traffic problems. By rearranging the transportation route and adding transportation vehicles, it ensures that the components arrive on time to avoid affecting the construction progress due to insufficient materials or transportation delays.

[0067] The re-planning unit 303 is used to obtain a supply chain threshold, which is the minimum requirement of the production plan, and compare the supply chain threshold with the monitoring data. If it is determined that the threshold is exceeded, the supply chain is re-planned.

[0068] In this module, the re-planning unit 303 obtains the supply chain threshold, which is the minimum requirement of the production plan and is used to determine whether the execution of a certain link in the supply chain meets the basic requirements of the production plan. The supply chain threshold is set based on historical data, production experience and demand forecast; For example, the material procurement threshold refers to the minimum purchase quantity of the required raw materials, the transportation threshold is the threshold of the transportation link, which usually involves transportation time, transportation distance and transportation capacity, and the storage threshold is the minimum quantity requirement for inventory; Compare the supply chain thresholds with the monitoring data. When the monitoring data shows that a certain link in the supply chain exceeds the preset threshold, immediate measures need to be taken to replan the supply chain to avoid affecting the overall production progress.

[0069] like Figure 8 As shown, as a preferred embodiment of the present invention, the energy module 400 includes: The energy demand unit 401 is used to obtain energy demand based on three-dimensional modeling, and the energy demand is the energy consumption limit of the station building.

[0070] In this module, the energy demand unit 401 obtains energy demand according to three-dimensional modeling, and uses energy analysis tools such as EnergyPlus to simulate based on the three-dimensional model of the station building, and calculates the energy consumption limit of the station building under different seasons and usage conditions. The energy consumption limit is affected by four factors: heat load, lighting load, ventilation load and equipment load; Heat load refers to the heat inflow and outflow of the station building, including heat conduction and radiation through walls, roofs, and windows, analyzing heating and cooling needs; lighting load refers to the energy demand for lighting inside the station building. It includes a combination of natural light and artificial lighting, as well as the energy efficiency of the lighting system; ventilation load refers to the energy consumed by the ventilation system of the station building; equipment load: the energy demand of the power equipment inside the station building, such as air conditioners, elevators, and computers.

[0071] The energy efficiency analysis unit 402 is used to obtain the energy efficiency analysis result of the current station building. The energy efficiency analysis is to simulate the energy performance of the station building through BIM. The energy performance simulation includes thermal performance, air conditioning load, lighting effect and energy consumption.

[0072] In this module, the energy efficiency analysis unit 402 obtains the energy efficiency analysis result of the current station building. The energy efficiency analysis is to simulate the energy performance of the station building through BIM. The energy efficiency analysis is a key step to ensure that the station building has lower energy consumption and higher comfort during operation. Energy performance simulation includes thermal performance, air conditioning load, lighting effect and energy consumption; thermal performance analysis focuses on factors such as heat conduction, heat radiation and heat convection of station buildings, and evaluates the heat load requirements of station buildings in different seasons; air conditioning load analysis focuses on calculating the air conditioning requirements of station buildings under different climatic conditions; lighting effect analysis evaluates the natural light conditions of station buildings in different seasons and times to ensure that there is enough daylight indoors, while avoiding excessive sunlight exposure that leads to reduced energy efficiency; energy consumption analysis is to calculate the total energy consumption of station buildings by comprehensively considering all energy use requirements of station buildings; Energy performance simulation of station buildings through BIM and energy efficiency analysis can help designers conduct a comprehensive station performance evaluation during the design phase, identify potential energy consumption problems in advance, and reduce energy waste through optimized design. For example, changing the facade material of the station building, optimizing the window design, adjusting the station building layout, and adopting an efficient air conditioning system can significantly improve the energy efficiency of the station building.

[0073] The renewable energy unit 403 is used to compare the current station energy efficiency analysis result with the energy demand. If the analysis result is less than the energy demand, the renewable energy design is increased.

[0074] In this module, the renewable energy unit 403 compares the current station energy efficiency analysis results with the energy demand to evaluate whether the energy efficiency of the existing station design can meet the predetermined energy consumption limit. If the energy efficiency analysis result of the station is lower than the energy demand of the station, then adding renewable energy design becomes an effective means to improve the energy performance of the station; When the energy efficiency result of the station building obtained through energy efficiency analysis is less than the energy demand of the station building, it means that the existing design of the station building may not be able to meet the prescribed standards or targets in terms of energy consumption. The shortfall can be compensated by adding renewable energy design to enhance the energy self-sufficiency of the station building while reducing dependence on traditional energy. For example, solar photovoltaic panels can be installed on the roof to convert solar energy into electricity.
