Description

Technical Field

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

[0002] For construction, carbon emissions account for a large proportion, have a large peak, are concentrated, and have a great impact on the environment, making it a key focus of energy conservation and emission reduction. At present, the measurement results of construction carbon emissions are generally displayed in the form of charts, which not only cannot intuitively show the location distribution comparison relationship and intensity comparison relationship of carbon emissions in various construction areas, but also cannot show the distribution relationship of carbon emissions in construction procedures and construction time.

[0003] The existing measurement results of construction carbon emissions can also be displayed by building a carbon emission model based on the construction stage. For example, the existing patent is a carbon emission assessment method and system based on 4D-BIM technology (application number: CN202410270978.3). First, determine the basic information of the building, divide the carbon emission stages of the building construction process, define the carbon emission calculation method of each stage and establish a digital model; then use BIM software to build a three-dimensional model of the building, then decompose the project, formulate a construction schedule, and calculate the carbon emissions of each stage with simulation results; integrate 4D-BIM technology to simulate the building visualization, and finally accurately calculate and evaluate carbon emissions. Although the above patent can observe the carbon emission relationship in the construction time, it is necessary to analyze the construction process, which leads to a complex model construction method, that is, the dynamic simulation model of the entire construction process is difficult to model, and the simulation process needs to ignore the influence of many construction uncertainties. The simulation results are far from the 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:

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 The present invention is a flowchart of a method for visualizing dynamic construction carbon emissions 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 only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include one or more of the 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: Combine 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 the resource consumption of each component during the construction process. According to the project construction drawing design and construction organization design, first determine the consumption data of labor, materials and mechanical energy in the construction, then classify these consumption data according to the sub-projects, and then obtain the carbon emission value of each process according to the carbon emission factors of various resources;

[0034] S200, the carbon emission data of each component obtained in step S100 is reallocated based on the input-output method, all labor, material and mechanical energy consumption in the construction process are regarded as project input, and the final completed construction building is regarded as project output. Based on the proportion of various materials in the cost of main project materials, all construction carbon emissions in the entire project are reallocated, and all carbon emissions are proportionally allocated to all main project materials; finally, according to the allocation results, the carbon emission value per unit quantity of each main project material after allocation is calculated;

[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] Since there are many sub-projects in 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, all of which belong to the main project; the other part includes earthwork engineering, support engineering, scaffolding engineering, formwork engineering, temporary construction engineering, and enclosure engineering, which belong to non-main engineering; 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 proportion of each main engineering material in all main engineering materials;

[0037] Since the more resources invested in producing a unit weight / volume of the material and the more complicated the process, the higher the carbon emission value of the material, the higher the monetary value of the material; therefore, according to the idea and principle 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, so as to keep the proportion of the material consumption cost in the total material cost of the main project unchanged;

[0038] S300, constructing a 3D BIM model. In order to intuitively display the distribution relationship between project output and carbon emissions, the 3D BIM building model established in the project design phase is used as a display carrier. The building model is divided into component boundaries according to the actual construction situation (i.e., the boundaries of each component are determined and the entire building model is split into several components), and the components are parametrically modified (parameterization means adding parameters to the components so that the size, volume, weight, type of constituent materials and content of the components can be called using parameters. Such data of all the same components in the model can be quickly and uniformly modified by modifying the parameter values. Parameters can also be used to write calculation formulas to achieve rapid calculation of the carbon emission values ​​of the model components), so that each component has parametric properties, including component volume / area / weight, type of constituent materials and consumption quantity parameters;

[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 , , root) to divide, such as 1m 3 Concrete, 1㎡ masonry, 1 precast beam, and a steel component, while maintaining all the parametric properties of the component in the smallest construction unit;

[0040] S500, associating process time, building a 4D BIM model, and associating each minimum construction unit of each component with the corresponding construction process and construction time according to the actual construction situation (by specifying time for each unit on the software, which is essentially model parameterization), including construction start time, end time, and duration, so that it presents 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, associating carbon emission characteristics and constructing a 5D BIM model. After the 4D BIM model is generated in step S500, the material consumption of each process of the smallest construction unit of each component is correlated with the corresponding position of 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 of each unit quantity of the main engineering material is input, and the parameterized attributes added to the component in step S300 are used for automatic calculation to obtain the carbon emission measurement data with construction output (building entity) as the carrier and changing with time series; finally, the two dimensions of progress and carbon emission are integrated on the basis of the 3D BIM model to form a 5D BIM model;

[0042] S700, visualizing the 5D BIM model obtained in step S600, including a dynamic distribution cloud map of carbon emissions per day for the smallest construction unit, a dynamic distribution cloud map of cumulative carbon emissions per smallest construction unit, a dynamic distribution cloud map of carbon emissions per day for building components, and a dynamic distribution cloud map of cumulative carbon emissions for building components, specifically including:

[0043] S710, dynamic distribution cloud map of daily carbon emissions of the smallest construction unit; taking day as the smallest unit of temporal change and the smallest construction unit as the statistical object, firstly sort the carbon emission values ​​of all the smallest construction units in the model every day, and then customize a gradient color card, divide the value range contained in the daily maximum and minimum carbon emissions of all the smallest construction units in the whole construction process in equal proportion, so that each color maps a certain value range (determined according to the selected color card, for example, if there are ten colors in the color card, this value range is divided into ten parts, each of which corresponds to a value range with the same span); then, according to the mapping relationship between the value and color of this gradient color card, each smallest construction unit presents the corresponding color according to the carbon emissions of the day, so as to produce the most intuitive and visual distribution cloud map of daily carbon emissions 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 whole construction process;

[0044] S720, dynamic distribution cloud map of the accumulated carbon emissions of the smallest construction unit; this method takes the day as the smallest unit of temporal change and the smallest construction unit as the statistical object, firstly sorts the accumulated carbon emission values ​​of all the smallest construction units in the model, then customizes a gradient color card, divides the value intervals contained in the accumulated maximum and minimum carbon emissions in equal proportion, and makes each color map to a certain value range; then, according to the mapping relationship between the value and color of this gradient color card, makes each smallest construction unit present the corresponding color according to the accumulated carbon emissions up to that day, thereby producing the most intuitive and visual distribution cloud map of the accumulated carbon emissions of the smallest construction unit; finally, these cloud maps are played continuously in chronological order to present the changes in the accumulated carbon emissions of each point in the entire construction process;

[0045] S730, dynamic distribution cloud map of daily carbon emissions of building components; this method uses day as the smallest unit of temporal change and components as statistical objects. First, the carbon emissions of the smallest construction units that constitute each component in the daily model are added up to form the daily carbon emissions of each component; then the carbon emission values ​​of all components in the model are sorted and a gradient color card is customized to divide the value ranges contained in the daily maximum and minimum carbon emissions of all construction units during the entire construction process in equal proportions, so that each color maps a certain value range; then, according to the mapping relationship between the value and color of this gradient color card, each component presents the corresponding color according to the 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 during the entire construction process;

[0046] S740. Dynamic distribution cloud map of cumulative carbon emissions of building components. This method uses day as the smallest unit of temporal change 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 gradient color card is customized 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 value and color of this gradient color card, each component presents a corresponding color according to the cumulative carbon emissions up to that day, thereby producing the most intuitive and visual distribution cloud map of cumulative carbon emissions of components. These cloud maps are played continuously in chronological order to present the changes in cumulative carbon emissions of various parts during the entire construction process.
