Description

Technical Field

[0001] The present invention relates to the technical field of carbon emission calculation, and in particular to a method and system for visualizing dynamic construction carbon emissions based on numerical simulation. Background Art

[0002] Construction, a sector with a significant proportion of carbon emissions, high peak emissions, concentrated emissions, and significant environmental impact, is a key area of ​​focus for energy conservation and emission reduction. Currently, construction carbon emissions measurement results are typically displayed in graphical form. This fails to visually demonstrate the locational distribution and intensity of carbon emissions across construction areas, nor does it reveal the distribution of carbon emissions across construction processes and timeframes.

[0003] Existing construction carbon emission measurement results can also be displayed by constructing a carbon emission model based on the construction phase. For example, a patented carbon emission assessment method and system based on 4D-BIM technology (application number: CN202410270978.3) first determines basic building information, divides the carbon emission phases of the building construction process, defines the carbon emission calculation method for each phase, and establishes a digital model. BIM software is then used to create a three-dimensional building model. The project is then broken down, a construction schedule is developed, and the carbon emissions for each phase are calculated based on the simulation results. 4D-BIM technology is then incorporated into the building for visualization and simulation, and finally, carbon emissions are accurately calculated and assessed. Although the aforementioned patent can observe carbon emission relationships over construction time, it requires analysis of the construction process, resulting in a complex model construction method. Specifically, the dynamic simulation model for the entire construction process is extremely difficult to build, and the simulation process must ignore the influence of numerous construction uncertainties. The simulation results differ significantly from actual construction resource consumption data, and the distribution of construction carbon emissions cannot be intuitively displayed. Moreover, the visualization of carbon emissions in the above-mentioned patent only adds the time sequence conditions based on the construction process, and is unable to display the implicit carbon emissions. The implicit carbon emissions display includes the daily carbon emissions and cumulative carbon emissions of each component and the daily carbon emissions and cumulative carbon emissions of the building body. The visualization effect is poor, and it is difficult to intuitively and in detail display the changes in carbon emissions during the construction process. Summary of the Invention

[0004] The technical problems to be solved by the present invention are:

[0005] In order to solve the problem that existing methods cannot visualize construction carbon emissions and cannot reflect the intrinsic connection between dynamic carbon emissions and the construction process.

[0006] The present invention is to solve the above technical problems using the following technical solutions:

[0007] The present invention provides a dynamic construction carbon emission visualization method based on numerical simulation, comprising the following steps:

[0008] S100. Collect resource consumption of each component during the construction process. Based on the project construction drawing design and construction organization design, determine the consumption data of labor, materials, and mechanical energy during the construction process. Calculate the carbon emission data of each process based on the classification of sub-projects and corresponding carbon emission factors.

[0009] S200. The carbon emission data for each process obtained in step S100 is reallocated based on the input-output method. All labor, materials, and mechanical energy consumed during the construction process are considered as project inputs, and the final completed construction building is considered as project output. Based on the proportion of each material in the main construction material cost, all construction carbon emissions in the entire project are reallocated, and all carbon emissions are proportionally allocated to all main construction materials. Finally, based on the allocation results, the carbon emission data per unit quantity of each main construction material after allocation is calculated.

[0010] S300, constructing a 3D BIM model. Using the 3D BIM building model established in the project design phase as a display carrier, the building model is divided into component boundaries according to the actual construction situation, and the components are parametrically modified so that each component has parametric properties;

[0011] S400, dividing the component into minimum construction units, dividing each component according to the minimum construction unit, while ensuring that the minimum construction unit has all parametric properties of the component;

[0012] S500, associating process time and building a 4D BIM model, associating each minimum construction unit of each component with the corresponding construction process and construction time according to the actual construction situation, and generating a 4D BIM model;

[0013] S600: Correlate carbon emission characteristics and construct a 5D BIM model. After the 4D BIM model is generated in step S500, the material consumption of each component's minimum construction unit in each process is correlated with the corresponding position in the BIM model. At the same time, the carbon emission value per unit quantity of each main engineering material is input. The parametric attributes added to the component in step S300 are used to automatically calculate and obtain carbon emission measurement data based on construction output and changing over time, ultimately forming a 5D BIM model.

[0014] S700 , visually presenting the 5D BIM model obtained in step S600 , including a dynamic distribution cloud map of daily carbon emissions of the minimum construction unit, a dynamic distribution cloud map of cumulative carbon emissions of the minimum construction unit, a dynamic distribution cloud map of daily carbon emissions of building components, and a dynamic distribution cloud map of cumulative carbon emissions of building components.

[0015] Furthermore, in step S200, the sub-projects include the main project and non-main project. When allocating, the carbon emissions generated by all personnel, all machinery and all non-main project materials in the construction project are located on all main project material entities in proportion.

[0016] Furthermore, in step S300, the parameters of each component include component volume / area / weight, component material type and consumption quantity.

[0017] Furthermore, in step S400, the minimum construction unit of each component includes 1m 3 Concrete, 1㎡ masonry, 1m steel pipe, a precast beam or a steel component.

[0018] Furthermore, in step S500, the associated data includes the construction start time, end time and duration.

[0019] Furthermore, in step S700, the following steps are included:

[0020] S710. When creating a dynamic distribution cloud map of daily carbon emissions for the minimum construction unit, use the day as the minimum unit of temporal change and the minimum construction unit as the statistical object. Sorting the carbon emission values ​​of all daily minimum construction units in the 5D BIM model obtained in step S600 is performed. A customized gradient color card is used to divide the numerical ranges of the maximum and minimum daily carbon emissions of all minimum construction units during the entire construction process into equal proportions, so that each color maps to a corresponding numerical range. Based on the mapping relationship between the values ​​on the gradient color card and the colors, each minimum construction unit is given a corresponding color according to the carbon emissions of that day, thereby obtaining a daily carbon emission distribution cloud map for the minimum construction unit.

[0021] S720. When creating a dynamic distribution cloud map of cumulative carbon emissions of minimum construction units, use the day as the minimum unit of temporal change and the minimum construction unit as the statistical object. Sort the cumulative carbon emission values ​​of all minimum construction units in the model. Customize a gradient color card to divide the numerical ranges of the maximum and minimum cumulative carbon emissions into equal proportions, so that each color maps to a corresponding numerical range. Based on the mapping relationship between the values ​​on the gradient color card and the colors, each minimum construction unit is given a corresponding color according to its cumulative carbon emissions as of that day, thereby obtaining a distribution cloud map of cumulative carbon emissions of the minimum construction units.

[0022] S730. When creating a dynamic distribution cloud map of daily carbon emissions of building components, take the day as the smallest unit of temporal change and the component as the statistical object, sum the daily carbon emissions of the smallest construction units that make up each component in the daily model to form the daily carbon emissions of each component; sort the daily carbon emission values ​​of all components in the model and customize a gradient color card, divide the numerical ranges contained in the daily maximum and minimum carbon emissions of all construction units throughout the construction process into equal proportions, and map each color to a corresponding numerical range; based on the mapping relationship between the gradient color card values ​​and colors, make each component appear in a corresponding color according to its daily carbon emissions, thereby obtaining a daily carbon emissions distribution cloud map of the components;

[0023] S740. When producing a dynamic distribution cloud map of the cumulative carbon emissions of building components, take days as the smallest unit of temporal change and components as the statistical objects, add up the cumulative carbon emissions of the smallest construction units that make up each component in the model to form the cumulative carbon emissions of each component; sort the cumulative carbon emission values ​​of all components in the model and customize a gradient color card, divide the numerical range contained in the cumulative maximum and minimum carbon emissions in equal proportion, and map each color to the corresponding numerical range; according to the mapping relationship between the gradient color card value and color, make each component present the corresponding color according to the cumulative carbon emissions as of that day, thereby obtaining a distribution cloud map of the cumulative carbon emissions of the component.

[0024] Furthermore, the cloud map obtained in step S700 is played continuously in chronological order, thereby presenting the cumulative carbon emission changes of each part during the entire construction process.

[0025] A dynamic construction carbon emission visualization system based on numerical simulation is provided. The system has a program module corresponding to the above steps and executes the steps in the above dynamic construction carbon emission visualization method based on numerical simulation when running.

[0026] A computer-readable storage medium stores a computer program configured to implement the steps of a dynamic construction carbon emission visualization method based on numerical simulation when called by a processor.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention provides a dynamic construction carbon emission visualization method and system based on numerical simulation, calculates carbon emissions based on process analysis method and input-output analysis method, visualizes carbon emissions based on numerical simulation, and divides the main structure into the smallest construction unit (m / ㎡ / m 3 / root / ), a dynamic project carbon emission intensity cloud map is generated according to the project implementation progress and construction sequence, thereby realizing the visualization of the distribution relationship, change relationship and comparison relationship of carbon emissions in time and space, and finally achieving the goal of visual presentation of construction carbon emissions; the present invention concentrates all carbon emissions in the construction project on the main structure for display, and presents different colors according to the size of the carbon emissions of each component in the building model, thereby forming a carbon emission intensity cloud map; the present invention ignores process analysis, and only considers the consumption in the construction process as the project input and the final construction building as the project output. The method of model construction is relatively simple, and on this basis, the visualization model is more detailed, that is, the two dimensions of construction progress and construction carbon emissions are integrated into the 3D BIM model, forming a more realistic, detailed and intuitive construction 5D The BIM model displays the dynamic distribution of daily carbon emissions of the smallest construction unit, the dynamic distribution of cumulative carbon emissions of the smallest construction unit, the dynamic distribution of daily carbon emissions of building components, and the dynamic distribution of cumulative carbon emissions of building components.

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 This is a flow chart of a dynamic construction carbon emission visualization method based on numerical simulation in an embodiment of the present invention. DETAILED DESCRIPTION

[0030] In the description of the present invention, it should be noted that the terms "first," "second," and "third" mentioned in the embodiments of the present invention are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, a feature specified as "first," "second," or "third" may explicitly or implicitly include one or more of such features.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Specific implementation plan 1: Combined Figure 1 As shown, the present invention provides a dynamic construction carbon emission visualization method based on numerical simulation, comprising the following steps:

[0033] S100. Collect resource consumption of each component during the construction process. Based on the project construction drawing design and construction organization design, first determine the consumption data of labor, materials, and mechanical energy during construction. Then, classify these consumption data according to sub-projects. Finally, calculate the carbon emission value of each process based on the carbon emission factor of each resource.

[0034] S200: Redistribute the carbon emission data for each component obtained in step S100 based on the input-output method, treating all labor, material, and mechanical energy consumed during the construction process as project inputs and the final completed building as project outputs. Based on the proportion of each material in the main construction material cost, all construction carbon emissions in the entire project are redistributed, allocating all carbon emissions proportionally to all main construction materials. Finally, based on the allocation results, calculate the carbon emission value per unit quantity of each main construction material after allocation.

[0035] This method ignores the complex and lengthy process analysis of resource consumption, matches all project inputs with outputs, and then attributes all project construction carbon emissions to the final building entity;

[0036] Because there are many sub-projects during the construction process, some of which include concrete engineering, masonry engineering, steel structure engineering, secondary structure engineering, ancillary facilities engineering, and decoration and renovation engineering. These sub-projects are all part of the main project; the other part includes earthwork engineering, support engineering, scaffolding engineering, formwork engineering, temporary construction engineering, and enclosure engineering, which are non-main engineering projects. Each of these sub-projects has corresponding human, material, and machine resource consumption. Therefore, it is necessary to locate the carbon emissions generated by all personnel, all machinery, and all non-main engineering materials in the construction project on all main engineering material entities according to the cost ratio of each main engineering material in the total main engineering materials.

[0037] Since the more resources invested in producing a material per unit weight / volume and the more complex the process, the higher the material's carbon emissions, and accordingly, the higher the monetary value of the material; therefore, according to the ideas and principles of the input-output method, the material consumption of each main project is converted into monetary form, and the proportion of each material cost in the main project is calculated, thereby maintaining the proportion of the material consumption cost in the total material cost of the main project unchanged;

[0038] S300. Construct a 3D BIM model. To visually demonstrate the distribution relationship between project output and carbon emissions, use the 3D BIM building model established during the project design phase as a display medium. Divide the building model into component boundaries according to actual construction conditions (i.e., determine the boundaries of each component and split the entire building model into several components). Parameterization is then performed on the components (parameterization is the process of adding parameters to components so that the size, volume, weight, type of constituent materials, and content of the components can be called using parameters. This allows for rapid and unified modification of such data for all identical components in the model by modifying parameter values. Parameters can also be used to compile calculation formulas to rapidly calculate the carbon emissions of model components). This allows each component to possess parametric properties, including parameters for component volume / area / weight, type of constituent materials, and quantity consumed.

[0039] S400, divide the components into the smallest construction unit. Since the duration of many construction processes varies from a few days to a few weeks, in order to more vividly and meticulously display the dynamic process of building construction, each component is divided into the smallest construction unit (m, m2, m 3 , pieces, roots) to divide, such as 1m 3 Concrete, 1㎡ masonry, 1 precast beam, and one steel component, while maintaining all the parametric properties of the components in the smallest construction unit;

[0040] S500: Associate process times and build a 4D BIM model. Based on the actual construction situation, associate each minimum construction unit of each component with the corresponding construction process and construction time (by specifying a time for each unit in the software, this is essentially model parameterization), including the construction start time, end time, and duration. This allows the model to present the overlap relationship and duration of each process consistent with the construction organization design, thereby generating a 4D BIM model that is closest to the actual construction.

[0041] S600: Associate carbon emission characteristics and construct a 5D BIM model. After the 4D BIM model is generated in step S500, the material consumption of each component's smallest construction unit in each process is correlated with the corresponding position in the BIM model (this correlation is to specify and add material consumption data for the corresponding unit in the model, which is essentially model parameterization). At the same time, the carbon emission value per unit quantity of each main engineering material is input. The parameterized attributes added to the component in step S300 are used for automatic calculation to obtain carbon emission measurement data based on construction output (building entity) and changing over time. Finally, the progress and carbon emission dimensions are integrated into the 3D BIM model to form a 5D BIM model.

[0042] S700: Visualize the 5D BIM model obtained in step S600, including a dynamic distribution cloud map of daily carbon emissions of the minimum construction unit, a dynamic distribution cloud map of cumulative carbon emissions of the minimum construction unit, a dynamic distribution cloud map of daily carbon emissions of building components, and a dynamic distribution cloud map of cumulative carbon emissions of building components, specifically including:

[0043] S710. Dynamic distribution cloud map of daily carbon emissions of the smallest construction unit. Taking the day as the smallest unit of temporal change and the smallest construction unit as the statistical object, first sort the carbon emission values ​​of all the smallest construction units in the model every day, then customize a gradient color card, and divide the numerical range contained in the maximum and minimum daily carbon emissions of all the smallest construction units in the entire construction process into equal proportions, so that each color maps a certain numerical range (determined by the selected color card, for example, if there are ten colors in the color card, this numerical range is divided into ten parts, each corresponding to a numerical range with the same span); then, based on the mapping relationship between the values ​​and colors of this gradient color card, each smallest construction unit is given a corresponding color according to the carbon emissions of that day, thereby producing the most intuitive and visual daily carbon emission distribution cloud map of the smallest construction unit; finally, these cloud maps are played continuously in chronological order to present the daily carbon emission changes of each point in the entire construction process;

[0044] S720. Dynamic distribution cloud map of cumulative carbon emissions of minimum construction units. This method uses days as the smallest unit of temporal change and minimum construction units as statistical objects. First, the cumulative carbon emission values ​​of all minimum construction units in the model are sorted. Then, a customized gradient color card is created to divide the numerical ranges contained in the maximum and minimum cumulative carbon emissions in equal proportion, so that each color maps a certain numerical range. Then, based on the mapping relationship between the values ​​and colors of this gradient color card, each minimum construction unit is given a corresponding color according to the cumulative carbon emissions as of that day, thereby producing the most intuitive and visual distribution cloud map of cumulative carbon emissions of minimum construction units. Finally, these cloud maps are played continuously in chronological order to present the changes in cumulative carbon emissions at each point throughout the construction process.

[0045] S730. Dynamic distribution cloud map of daily carbon emissions of building components. This method uses days as the smallest unit of temporal change and components as statistical objects. First, the daily carbon emissions of the smallest construction units that make up each component in the daily model are added together to form the daily carbon emissions of each component. Then, the carbon emission values ​​of all components in the model are sorted and a customized gradient color card is used to divide the numerical ranges contained in the daily maximum and minimum carbon emissions of all construction units throughout the construction process into equal proportions, so that each color maps a certain numerical range. Then, based on the mapping relationship between the values ​​and colors of this gradient color card, each component is given a corresponding color according to its daily carbon emissions, thereby producing the most intuitive and visual component daily carbon emission distribution cloud map. These cloud maps are played continuously in chronological order to present the daily carbon emission changes of each part throughout the construction process.

[0046] S740. Dynamic distribution cloud map of cumulative carbon emissions of building components. This method uses days as the smallest unit of temporal changes and components as statistical objects. First, the cumulative carbon emissions of the smallest construction units that make up each component in the model are added together to form the cumulative carbon emissions of each component. Then, the cumulative carbon emission values ​​of all components in the model are sorted and a customized gradient color card is used to divide the numerical range contained in the cumulative maximum and minimum carbon emissions in equal proportion, so that each color maps a certain numerical range. Then, based on the mapping relationship between the values ​​and colors of this gradient color card, each component is given a corresponding color according to the cumulative carbon emissions as of that day, thereby producing the most intuitive and visual distribution cloud map of the cumulative carbon emissions of the components. By playing these cloud maps continuously in chronological order, the changes in the cumulative carbon emissions of each part during the entire construction process can be presented.
