Description

Technical Field

[0001] This invention relates to the technical field of carbon emission calculation, and more particularly to a method for automatically calculating the carbon emissions of rapid transit projects. Prior Technology

[0002] Currently, the method for calculating the carbon emissions of MRT engineering units involves copying the corresponding content from a MRT budget into an Excel file, and then calculating the carbon emissions of different projects within the MRT engineering unit within the Excel working environment to generate a carbon emission calculation result table for different MRT routes and / or stations. The Excel file generates this carbon emission calculation result table by collecting basic information about the MRT project and then breaking it down into detailed items, such as station name, type, length, width, and projected area, as well as route name, type, length, width, and projected area.

[0003] However, the percentages of each item in the carbon emission calculation results table are filled in and calculated based on the experience of engineers, and cannot be calculated immediately or automatically based on previous similar engineering projects, which can easily lead to subsequent human errors or a gradual increase in errors. Summary of the Invention

[0004] The purpose of this invention is to provide a method for automatically calculating the carbon emissions of MRT projects. The method can calculate the carbon emissions of MRT projects through MRT budget, carbon emission coefficient database and equivalent conversion concepts on a carbon emission estimation auxiliary platform, thereby avoiding human error or the gradual increase of error.

[0005] To achieve the aforementioned objectives, this invention provides a method for automatically calculating the carbon emissions of a rapid transit project, comprising a budget classification step: uploading budget data to a carbon emission estimation assistance platform, the budget data mainly including multiple engineering projects and a resource statistics table; using a tag module of the carbon emission estimation assistance platform to classify the engineering projects in the budget data into different types of engineering projects; and linking the resource statistics table to a corresponding carbon emission coefficient in a carbon emission coefficient database of the carbon emission estimation assistance platform through a carbon emission coefficient linking module, thereby calculating the carbon emissions of different types of engineering projects. Volume estimation process; Equivalent analysis steps: Basic data on different MRT project bids and various types of projects are collected through a planning data module in an equivalent analysis platform as the basis for subsequent budget equivalent conversion and carbon emission equivalent conversion. In the budget equivalent conversion, based on the total budget of each project type after classification by the label module, the project data module confirms the award year, base year, and price index of each MRT project bid. This information is then transmitted to the price adjustment module of the budget equivalent module in the equivalent analysis platform for automatic budget consistency. The adjustments are made to bring the budgets of these MRT project bids back to the same price level. Based on the adjusted budgets from the price bidding adjustment module and the basic data of different types of projects from the project data module, the budget equivalent is converted, and a budget equivalent database is established. Simultaneously, in the carbon emission equivalent conversion, based on the total carbon emissions of different types of projects categorized by the labeling module, the project data module of the equivalent analysis platform is used to confirm the award year and base year of each MRT project bid. The basic data of different types of engineering projects are used to convert carbon emission equivalents, and a carbon emission equivalent database is established by compiling the converted carbon emission equivalents. The carbon emission estimation steps are as follows: The maximum budget value for each type of engineering project is selected from the budget equivalent database and multiplied by an appropriate budget amplification factor to serve as a budget baseline for each type of engineering project during the planning stage. Simultaneously, the maximum carbon emission value for each type of engineering project is selected from the carbon emission equivalent database and multiplied by an appropriate carbon emission amplification factor to serve as a carbon emission baseline for each type of engineering project during the planning stage.The process includes a BIM (Building Information Modeling) component equivalent estimation step: The budget equivalent of a BIM component in the budget equivalent database is automatically entered into the BIM component information field. This allows for the estimation of the total budget for each project project through a combination of BIM components. Simultaneously, the carbon emission equivalent of the BIM component in the corresponding carbon emission equivalent database is automatically entered into the BIM component information field. This allows for the estimation of the total carbon emissions for each project project through a combination of BIM components. The total budget estimated in this BIM component equivalent estimation step approximates the total budget in the equivalent analysis step.

[0006] In some embodiments, the budget document is an XML file.

[0007] In some embodiments, the different types of the project that have been classified include at least underground stations, elevated stations, tunnels, viaducts, main substations, depots, connecting passages, and escape shafts / ventilation shafts.

[0008] In some embodiments, the carbon emission coefficient linking module has a built-in budget code for each project and a corresponding relationship with the carbon emission coefficient. Therefore, after the budget data is uploaded to the carbon emission estimation auxiliary platform, the carbon emission coefficient linking module automatically links the corresponding carbon emission coefficient for most resources. The remaining few resource items with project-specific characteristics are manually linked to reduce human error. The resource includes all manpower, equipment, and materials used in the MRT project. Each project has a budget for the manpower, equipment, and materials used in the project. The resource statistics table summarizes the quantity and budget of manpower, equipment, and materials for each project.

[0009] In some embodiments, the principle for selecting the budget code and the carbon emission coefficient in the correspondence with the carbon emission coefficient is to score the carbon emission coefficients of the same resource according to a predetermined condition of year and source through a genealogy matrix, so as to ensure data quality, select the data with high quality, and complete the establishment of its relationship with the budget code.

[0010] In some embodiments, the carbon emission coefficient database includes carbon emission coefficients collected from various resources over the years. The carbon emission coefficient database is continuously updated on a rolling basis based on locally available carbon emission coefficient data that can be collected from the public internet and carbon emission coefficients collected from other carbon audit projects.

[0011] In some embodiments, the budget equivalent database includes a database of budget representative values ​​for different types of engineering projects and a database of budget characteristic values. The database of budget representative values ​​is created by plotting the budget equivalents of the same type of engineering projects in the MRT engineering tenders on the same budget quadrant chart to summarize the budget representative average value of the types of engineering projects and to explore which budget characteristic values ​​cause the difference between a budget dispersion value and a budget representative value. The database of budget characteristic values ​​is established by classifying the budget equivalent as a higher or lower value relative to the budget representative value, to indicate that the engineering project has its own special conditions.

[0012] In some embodiments, the carbon emission equivalent database includes a database of representative carbon emission values ​​for different types of engineering projects and a database of carbon emission characteristic values. The database of representative carbon emission values ​​is created by plotting the carbon emission equivalents of the same type of engineering projects in the metro engineering tenders on the same carbon emission quadrant chart to summarize the representative average carbon emission value for the type of engineering projects and to explore the differences between a carbon emission discrete value and a carbon emission representative value, and to identify which carbon emission characteristic values ​​are causing the differences, thereby establishing the carbon emission characteristic value database. The carbon emission equivalent value in the carbon emission characteristic value database is a higher or lower value than the carbon emission representative value, indicating that the engineering project has its own special conditions.

[0013] In some embodiments, the resource statistics table refers to all the resources required in the budget document, with no duplicate resource items. If any duplicate resources are used in different projects, they will be summed up in the resource statistics table.

Implementation

[0016] The advantages, features, and technical methods of this invention will be more readily understood by referring to the exemplary embodiments and accompanying drawings. This invention may be implemented in different forms and should not be construed as being limited to the embodiments set forth herein. Rather, the embodiments provided will make this disclosure more thorough, complete, and fully convey the scope of the invention to those skilled in the art, and the invention will be defined only as provided in the appended claims.

[0017] Additionally, the terms "comprising" and / or "including" refer to the presence of the stated features, regions, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, regions, wholes, steps, operations, elements, components, and / or combinations thereof.

[0018] To facilitate your understanding of the contents of this invention and the effects it can achieve, the following detailed description is provided in conjunction with the accompanying drawings of various specific embodiments.

[0019] Figure 1 is a flowchart illustrating the method for automatically calculating the carbon emissions of a rapid transit project according to the present invention. Figure 2 is a block diagram illustrating the structure of the present invention for automatically calculating the carbon emissions of a rapid transit project.

[0020] Please refer to Figure 1. The method S100 for automatically calculating the carbon emissions of a subway project according to the present invention includes steps S110 to S140, which will be described in detail below. The method S100 for automatically calculating the carbon emissions of a subway project according to the present invention can be executed through the structure for automatically calculating the carbon emissions of a subway project shown in Figure 2.

[0021] Step S110 is a budget classification step. In step S110, budget data is uploaded to a carbon emission estimation auxiliary platform. The budget data mainly includes multiple engineering projects and a resource statistics table. Through a tag module of the carbon emission estimation auxiliary platform, the engineering projects in the budget data are classified into different types of engineering projects. The resource statistics table is linked to a corresponding carbon emission coefficient in the carbon emission coefficient database of the carbon emission estimation auxiliary platform through a carbon emission coefficient linking module, so as to perform carbon emission estimation for different types of engineering projects. For example, an engineering type can be composed of several engineering projects. For example, Station A is an engineering type of "two-level underground station", which is composed of engineering projects such as "continuous wall", "structure", "architecture", and "water ring".

[0022] Figure 3 is a schematic diagram of a step performed by a carbon emission estimation auxiliary platform in the method for automatically calculating the carbon emissions of MRT projects according to the present invention.

[0023] For example, referring to Figures 1, 2, and 3, step S110 (i.e., the budget classification step) can be performed through a carbon emission estimation auxiliary platform 100. The carbon emission estimation auxiliary platform 100 may include a tag module 110, a carbon emission coefficient database 120, and a carbon emission coefficient link module 130. By uploading the XML file of the budget document (i.e., the budget document D1 shown in Figure 2) to the carbon emission estimation auxiliary platform 100, the carbon emission estimation auxiliary platform 100 (e.g., the backend) automatically parses the budget document data. The budget document data can be classified into various engineering projects on the carbon emission estimation auxiliary platform 100 through the tag module 110. The platform backend automatically parses the budget document data for use by the subsequent equivalent analysis platform 200. The classification categories need to take into account the possible combinations of engineering types required by future new tenders (i.e., MRT engineering tenders or MRT engineering projects), including at least underground stations, elevated stations, tunnels, viaducts, main substations, depots, connecting passages, and escape shafts / ventilation shafts, but the present invention is not limited thereto.

[0024] The structure of Budget D1 mainly includes various engineering projects and Resource Statistics Table D2. Resource Statistics Table D2 refers to all the resources required in total in Budget D1. The resource items are not duplicated, and if any engineering projects use the same resources, they will be summed in Resource Statistics Table D2. Therefore, step S110 (i.e., the budget classification step) utilizes the characteristics of Budget D1 and the carbon emission coefficient connection module 130 in the carbon emission estimation auxiliary platform 100 to connect the data in Resource Statistics Table D2 in Budget D1 to the carbon emission coefficient database 120 for the corresponding carbon emission coefficient, in order to perform carbon emission estimation for each engineering project. The carbon emission coefficient linking module 130 can be built into a budget code for each project of the MRT project and a corresponding relationship with the carbon emission coefficient. Therefore, after uploading the XML file of the budget document D1 (i.e., budget document data) to the carbon emission estimation auxiliary platform 100, the carbon emission coefficient of most resources can be automatically linked through the carbon emission coefficient linking module 130. The remaining few resource items with project-specific characteristics are then manually linked to reduce human error. Therefore, the carbon emission estimated by the automatic calculation method S100 of the MRT project of this invention has consistency and comparability.

[0025] It should be understood that "resources" refers to all the "human resources," "equipment," and "materials" that will be used in this MRT project. Each project will have a "budget" for the human resources, equipment, and materials that will be used in that project. Therefore, it can be said that the resource statistics table summarizes the quantity and budget of human resources, equipment, and materials (i.e., people / machines / materials) for each project.

[0026] In addition, the budget code and its correspondence with the carbon emission coefficient established in step S110 (i.e., the carbon emission estimation auxiliary step) can be selected by using a phylogenetic matrix to score the carbon emission coefficients of the same resources according to their year, source and other conditions to ensure data quality. The data with high quality is selected and its relationship with the budget code is established.

[0027] In some embodiments, the carbon emission coefficient database 120 may be built into the carbon emission estimation auxiliary platform 100, and may include carbon emission coefficients collected from various resources over the years. The carbon emission coefficient database 120 may also be continuously updated in a rolling manner based on local carbon emission coefficient data that can be collected from the public network and carbon emission coefficients collected from other carbon audit projects.

[0028] Step S120 is an equivalent analysis step. In step S120, basic data of different MRT engineering bids and basic data of various types of engineering projects are collected through a planning data module in an equivalent analysis platform as the basis for subsequent budget equivalent conversion and carbon emission equivalent conversion. In the budget equivalent conversion, based on the total budget of each type of engineering project after classification by the label module, the bidding year, base year, and price index of each MRT engineering bid are confirmed by the planning data module and transmitted to the price bidding adjustment module of the budget equivalent module of the equivalent analysis platform. The module automatically adjusts the budget for consistency so that the budgets of these MRT engineering bids return to the same price level. The adjusted budget from the price bidding adjustment module and the basic data of various types of engineering projects from the planning data module are used to perform budget equivalent conversion, and a budget equivalent database is established by compiling the budget equivalent conversion. At the same time, in the carbon emission equivalent conversion, based on the total carbon emissions of various types of engineering projects classified by the label module, the planning data module of the equivalent analysis platform is used to confirm the award year and base year of each MRT engineering project tender. Based on the basic data of various types of engineering projects from the planning data module, the carbon emission equivalent conversion is performed, and a carbon emission equivalent database is established by compiling the carbon emission equivalent conversion.

[0029] Figure 4 is a schematic diagram of a step performed through an equivalent analysis platform in the method of automatically calculating the carbon emissions of MRT projects according to the present invention.

[0030] For example, referring to Figures 1, 2, and 4 simultaneously, step S120 (i.e., the equivalent analysis step) can be performed through an equivalent analysis platform 200. The equivalent analysis platform 200 may include a project data module 210, a budget equivalent module 220, and a carbon emission equivalent module 230. The equivalent analysis platform 200 can be configured to receive data transmitted from the carbon emission estimation auxiliary platform 100, and further convert it into budget equivalents and carbon emission equivalents for various project types. The equivalent analysis platform 200 may include a project data module 210, a budget equivalent module 220, and a carbon emission equivalent module 230.

[0031] "Budget equivalent" can be defined as the standard for normalizing the budget of various project types using engineering geometric conditions such as area and length, so as to facilitate subsequent application to budget estimation for other projects of different scales. The concept of equivalent normalization conversion is explained below.

[0032] Taking a station-type project as an example, the project includes station A and station B, both of which are two-level underground stations. The budget equivalent of station A is calculated as (station A budget) / station A area, and the budget equivalent of station B is calculated as (station B budget) / station B area. Therefore, the budget equivalents of several previous two-level underground stations can be collected to form a budget equivalent database 222 for two-level underground stations. The budget equivalent database 222 can be included in the budget equivalent module 220.

[0033] Taking tunnel projects as an example, the project includes tunnels A and B, both of which are traditional shield tunnels (6.1m outer diameter, traditional circular tunnels). The budget equivalent of tunnel A is calculated as (Tunnel A budget) / Tunnel A length, and the budget equivalent of tunnel B is calculated as (Tunnel B budget) / Tunnel B length. Therefore, the budget equivalents of several traditional circular tunnels can be collected to form a budget equivalent database 222 for traditional circular tunnels. This budget equivalent database 222 can be included within the budget equivalent module 220.

[0034] The definition of "carbon emission equivalent" is similar to the concept of "budget equivalent". The only difference is that the budget is replaced with the carbon emission amount corresponding to each type of project, and the carbon emission equivalent is collected to form a carbon emission equivalent database 232. The carbon emission equivalent database 232 can be contained in the carbon emission equivalent module 230.

[0035] In some embodiments, the planning data module 210 is configured to collect basic information on different tenders (i.e., MRT project tenders or MRT project projects) and basic information on each type of project, as a basis for subsequent budget equivalent and carbon emission equivalent conversion. Please refer to Figure 4. The basic information mentioned above may include the month of awarding the contract (D3), the price level (D4), the contracting level (D5), the project type and its basic information (D6) (e.g., 2 underground stations + 3 sections of shield tunnels, their respective areas, lengths, and geological formations). Among these, the month of awarding the contract (D3) and the price level (D4) significantly affect the value of the budget equivalent. Since step S120 (i.e., the equivalent analysis step) organizes the budget documents (D1) of the projects awarded over the years through the equivalent analysis platform 200 mechanism, and the month of awarding the contract and the price level are different for each project, different years / months represent different price levels. For example, due to the impact of COVID-19, international wars and labor shortages in the construction market, the budget for 2021 may be lower than that for 2025. Therefore, the budget document (D1) (i.e., the budget document data) cannot be directly used for organization. It must be adjusted and converted to the same calculation basis through the price level (D4) or the contracting level (D5) before comparison can be made. The price level D4 can be adjusted through a price contracting adjustment module 223, which can be included in the budget equivalent module 220 of the equivalent analysis platform 200.

[0036] For example, the bidding month D3 is October 2021. The price level D4 is defined as the price adjustment value corresponding to the year / month, automatically retrieved from the price index table updated on the 15th of each month by the Directorate-General of Budget, Accounting and Statistics through a web crawler program by the Equivalent Analysis Platform 200 (website: https: / / www.stat.gov.tw / cp.aspx?n=2665), corresponding to the bidding month October 2021. The base month is set as October 2025. Therefore, (budget in October 2025) = (budget in October 2021) * (price index in October 2025) / (price index in October 2025).

[0037] The definition of the contract level D5 is based on the changes in the amount of historical MRT tenders from the first announcement to the award of the contract, analyzed by the Equivalent Analysis Platform 200, and the relationship between each tender. It also compiles the same price index table and can perform the conversion of the corresponding tendering year and month. The calculation method is the same as the price level.

[0038] Additionally, for example, "project type" can include at least station type, tunnel type, viaduct type, cut-and-cover tunnel, connecting passage, and ventilation shaft / escape shaft. In some embodiments, basic information for a station type includes records of the station's floors, length, width, depth, area, soil cover depth, stratum, and whether there are any special features (crossroads, major pipeline relocation, special architectural style, etc.). Station types can be further classified into underground stations and elevated stations. Underground stations include general stations (two, three, four, and five levels) and transfer stations (three, four, and five levels). Elevated stations also include general stations and transfer stations. A general station of an elevated station includes the station body (two, three, four, and five levels) and entrances / exits. The entrances / exits of a general station of an elevated station also include general entrances / exits (two, three, and four levels) and combined entrances / exits (two, three, and four levels). The classification of transfer stations of elevated stations is the same as that of general stations of elevated stations, so it will not be described again.

[0039] In some embodiments, the basic information of the tunnel type includes records of the shield tunnel's dimensions, length, overburden depth, strata, annular material, number of working shafts, etc. The tunnel type can be a shield tunnel, and shield tunnels include general tunnels (traditional circular tunnels), general tunnels (special circular tunnels), and mountain tunnels.

[0040] In some embodiments, basic information about viaducts includes records of the viaduct's length, foundation type, geological strata, and any special features (such as major pipeline relocation). Viaducts can be further classified into concrete bridges and steel bridges. Concrete bridges include in-situ cast U-shaped, precast U-shaped, in-situ cast box girder, and in-situ cast cantilever bridges. Steel bridges include box girder, U-shaped, and stacked girder bridges.

[0041] In some embodiments, basic information about cut-and-cover tunnel sections includes recorded length and whether there are any special geological features (such as major pipeline relocation, etc.). Cut-and-cover tunnel types can be classified as central bypass, crossroads, and excavation sections. In some embodiments, basic information about connecting passages includes form (horizontal / vertical) and geological strata. In some embodiments, basic information about ventilation shafts / escape shafts includes depth and geological strata.

[0042] Referring to Figures 1, 2, and 4, the budget equivalent module 220 may include a price adjustment module 223, a budget equivalent conversion module 221, and a budget equivalent database 222. The function of the price adjustment module 223, as described above, is to process the total budget for each project type after it has been categorized according to the label module 110 of the carbon emission estimation auxiliary platform 100. This budget is then processed by the project data module 210 of the equivalent analysis platform 200 to confirm the award year, base year, and price index of the project. The result is then automatically adjusted by the price adjustment module 223 within the budget equivalent module 220 to ensure budget consistency, bringing the budgets of several projects back to the same price level for comparability.

[0043] Furthermore, the equivalent conversion module 221 can be configured to convert the budget equivalents of various project types according to the adjusted budget of the price bidding adjustment module 223 and the project type and basic data D6 of the planning data module 110. For example, the total budget of a 1000m tunnel can be converted into the budget equivalent per meter so that it can be used for data exchange with other projects.

[0044] Additionally, the budget equivalent database 222 can be configured to aggregate the budget equivalent data processed by the equivalent conversion module 221 to establish a budget equivalent database for MRT projects. The budget equivalent database 222 may include a budget representative value database 224 and a budget characteristic value database 225 for each project type. In some embodiments, the budget representative value database 224 can be configured to plot the budget equivalents of the same project type on the same budget quadrant chart to summarize the budget representative average value of that project type and explore the differences between a budget discrete value and a budget representative value, and which budget characteristic values ​​cause the differences, such as special ring material, deeper soil cover, more entrances and exits, more complex pipeline relocation, etc., thereby establishing the budget characteristic value database 225. The budget characteristic value database 225 represents budget equivalent values ​​that are either higher or lower than the representative values. This indicates that the project has special conditions, such as deeper soil cover, more entrances and exits, or more complex pipeline relocation. It is compiled into a budget characteristic value database for various project types to be used in the design phase to confirm whether the design results are consistent with past experience.

[0045] When applied to the design phase to verify the rationality of the results, the budget equivalent representative value of the corresponding project is selected from the budget representative value database 224, and it is confirmed whether the project meets the budget characteristic value conditions. If so, the value in the budget characteristic value database 225 is added to obtain the budget equivalent of the project. Multiplying this value by the conditions of the project gives the total budget of the project.

[0046] Figure 7 is a schematic diagram illustrating the expected results of an embodiment of the method for automatically calculating the carbon emissions of a rapid transit project according to the present invention, in which a budget / carbon equivalent database is used to estimate the budget or carbon emissions of a project type during the design phase.

[0047] For example, referring to Figure 7, for a three-level underground station, its length, width, number of entrances / exits, and soil cover depth are known from the design results. A representative budget value for the three-level underground station is selected from the representative budget value database 224, and a characteristic budget value that meets the characteristic conditions is selected from the characteristic budget value database 225. Therefore, the budget equivalent of this three-level underground station = the representative budget value + the characteristic budget value, and the total budget of this three-level underground station = the equivalent budget value of this three-level underground station. The station area can be compared and confirmed with past budget data to ensure that the budget is not too conservative or insufficient.

[0048] In some embodiments, as shown in FIG4, the carbon emission equivalent module 230 may include a carbon emission equivalent conversion module 231 and a carbon emission equivalent database 232, which are basically the same as the concept of the budget equivalent module 220, except that the price adjustment part is omitted, because the price adjustment part only involves the adjustment of the budget and does not affect the carbon emission. The carbon emission equivalent database 232 simply replaces the budget part of each project type with the carbon emission amount, and the rest of the concepts are the same. In other words, the carbon emission equivalent database 232 may include a carbon emission representative value database 233 and a carbon emission characteristic value database 234 for each type of project. The carbon emission representative value database 233 is configured to plot the carbon emission equivalents of the same type of engineering projects in the MRT engineering tenders on the same carbon emission quadrant chart, in order to summarize the representative average carbon emission value of the type of engineering projects, and to explore the differences between a carbon emission discrete value and a carbon emission representative value, and to establish a carbon emission characteristic value database. The carbon emission equivalent value in the carbon emission characteristic value database is a higher or lower value than the carbon emission representative value, so as to indicate that the engineering project has its own special conditions.

[0049] Step S130 is a carbon emission estimation step. In step S130, a maximum budget value for each type of project is selected from the budget equivalent database and multiplied by an appropriate budget amplification factor to serve as a budget baseline for each type of project in the planning stage. At the same time, a maximum carbon emission value for each type of project is selected from the carbon emission equivalent database and multiplied by an appropriate carbon emission amplification factor to serve as a carbon emission baseline for each type of project in the planning stage.

[0050] In detail, during the entire lifecycle execution of a subway project (including planning, design, construction, and operation phases), it is necessary to estimate a reasonable budget baseline and a carbon emission baseline at the very beginning of the planning phase. These will serve as a benchmark for carbon reduction planning in the subsequent design phase. It is essential to know the potential carbon emissions of the project before focusing on carbon reduction design.

[0051] Figure 5 is a schematic diagram of a step performed through a budget / carbon emission estimation platform in the method for automatically calculating the carbon emissions of MRT projects according to the present invention. Figure 8 is a schematic diagram of an embodiment of the expected results of an embodiment of the method for automatically calculating the carbon emissions of MRT projects according to the present invention, in which a budget / carbon emission equivalent database is used to establish budget baselines and carbon emission baselines during the planning stage.

[0052] For example, referring to Figures 1, 2, 5, and 8, step S130 (i.e., the carbon emission estimation step) can be performed through a carbon emission estimation platform 300. The carbon emission estimation platform 300 may include a budget estimation module 310 and a carbon emission estimation module 320. The budget estimation module 310 can be configured to select a maximum budget value for each project type based on the budget equivalent database 222 within the budget equivalent module 220 of the equivalent analysis platform 200, and multiply it by an appropriate budget amplification factor (i.e., the estimation result will be adjusted through a multiplier correction method based on the influence of risk factors and design uncertainty parameters) as a project budget baseline for that project type in the planning stage, serving as a reference benchmark for volume reduction in the subsequent design stage. The carbon emission estimation module 320 is essentially equivalent to the budget estimation module 310. Both use the carbon emission equivalent database 232 within the carbon emission equivalent module 231 of the equivalent analysis platform 200 to select a maximum carbon emission value for the project type and multiply it by an appropriate carbon emission coefficient (i.e., the estimation result will be adjusted through a multiplier correction method based on the influence of risk factors and design uncertainty parameters). This serves as a project carbon emission baseline for the project type during the planning stage and as a reference benchmark for carbon reduction in the subsequent design stage.

[0053] Step S140 is a BIM (Building Information Modeling) component equivalent estimation step. In step S140, the budget equivalent of a BIM component in the budget equivalent database is automatically filled into a BIM component information field to estimate the total budget of each project through the combination of BIM components. At the same time, the carbon emission equivalent of the BIM component in the carbon emission equivalent database is automatically filled into the BIM component information field to estimate the total carbon emissions of each project through the combination of BIM components.

[0054] For example, the total budget in step S120 (i.e., the equivalent analysis step) can be mapped back to each engineering project. However, step S140 (i.e., the BIM component equivalent estimation step) is a BIM component equivalent value composed of several equivalents. This is because BIM components cannot be built in great detail and cannot be mapped to all budget items. For instance, in the underground station BIM model, only three types of BIM components can be built during the planning stage: continuous walls, walls, and slabs. However, it is necessary to map "all" budget items to these three types of components. Only after the BIM models are combined can the calculated total budget be as close as possible to the total budget estimated by the equivalents. Therefore, the estimated total budget in step S140 (i.e., the BIM component equivalent estimation step) is close to the total budget in step S120 (i.e., the equivalent analysis step).

[0055] In some embodiments, the budget equivalent and carbon emission equivalent to be filled in the information field of BIM components are also derived from the budget. Therefore, after linking the carbon emission coefficient from the resource statistics table, the budget / carbon emission of each project is summarized. After the equivalent conversion, the relevant budget / carbon emission equivalents are summarized and written into the information field of the BIM component.

[0056] Figure 9 is a schematic diagram illustrating how BIM elements are incorporated into the budget equivalent and carbon emission equivalent in the method for automatically calculating the carbon emissions of a rapid transit project according to the present invention, in order to estimate the total budget and total carbon emissions of the rapid transit project plan.

[0057] For example, referring to Figures 1, 2, 6 and 9, step S140 (i.e., the BIM component equivalent estimation step) can be performed through a BIM component equivalent database 400. The BIM component equivalent database 400 may include a BIM component budget equivalent module 410 and a BIM component carbon emission equivalent module 420.

[0058] In some embodiments, the BIM element budget equivalent module 410 can be configured to automatically fill a BIM element information field 430 with the value of the budget equivalent corresponding to a BIM element (e.g., the maximum value 411 in the budget equivalent database 222 in the budget equivalent module 220 of the equivalent analysis platform 200) based on the budget equivalent database 222, so as to estimate the total budget of a project (e.g., a metro project tender) through the combination of such BIM elements.

[0059] In some embodiments, the BIM element carbon emission equivalent module 420 is essentially equivalent to the concept of the BIM element budget equivalent module 410. It can be configured to automatically fill the BIM element information field 430 with the value of the carbon emission equivalent corresponding to the BIM element (e.g., the maximum value 421 in the carbon emission equivalent database) so as to estimate the total carbon emissions of a project (e.g., a metro project tender) through the combination of these BIM elements.

[0060] By using the structure 10 and method S100 for automatically calculating the carbon emissions of MRT projects, the carbon emissions of MRT projects can be calculated on the carbon emission estimation auxiliary platform 100 using the MRT project budget D1, carbon emission coefficient database 120, and the concept of equivalent conversion, thereby avoiding human error or the gradual increase of error.

Claims

1. A method for automatically calculating the carbon emissions of a rapid transit project, comprising: A budget classification process involves uploading budget data to a carbon emission estimation assistance platform. This budget data mainly includes multiple engineering projects and a resource statistics table. The platform uses a tag module to classify the engineering projects in the budget data into different types of engineering projects. The resource statistics table is linked to the corresponding carbon emission coefficient in the carbon emission coefficient database of the platform through a carbon emission coefficient link module, in order to perform carbon emission estimation for different types of engineering projects. The first step of the equivalent analysis is as follows: Basic data on different MRT project bids and various types of projects are collected through a planning data module within the equivalent analysis platform. This data serves as the basis for subsequent budget equivalent conversion and carbon emission equivalent conversion. In the budget equivalent conversion, based on the total budget of each project categorized by the labeling module, the project data module confirms the award year, base year, and price index for each MRT project bid. This information is then transmitted to the price adjustment module within the budget equivalent module of the equivalent analysis platform. This automatically adjusts the budgets to ensure consistency, bringing the budgets of each MRT project bid back to the same price level. The adjusted budget from the price bidding adjustment module and the basic data of various types of engineering projects from the planning data module are used to perform budget equivalent conversion, and a budget equivalent database is established by compiling the budget equivalent conversion. At the same time, in the carbon emission equivalent conversion, based on the total carbon emissions of various types of engineering projects classified by the label module, the planning data module of the equivalent analysis platform is used to confirm the award year and base year of each MRT engineering project bid, and the carbon emission equivalent is converted based on the basic data of various types of engineering projects from the planning data module. A carbon emission equivalent database is established by compiling the carbon emission equivalent conversion. One carbon emission estimation step: Select the maximum budget value for each type of project through the budget equivalent database, and multiply it by an appropriate budget amplification factor to serve as a budget baseline for each type of project in the planning stage. At the same time, select the maximum carbon emission value for each type of project through the carbon emission equivalent database, and multiply it by an appropriate carbon emission amplification factor to serve as a carbon emission baseline for each type of project in the planning stage.The process includes a BIM (Building Information Modeling) component equivalent estimation step: The budget equivalent of a BIM component in the budget equivalent database is automatically entered into the BIM component information field. This allows for the estimation of the total budget for each project bid through a combination of BIM components. Simultaneously, the carbon emission equivalent of the BIM component in the corresponding carbon emission equivalent database is automatically entered into the BIM component information field. This allows for the estimation of the total carbon emissions for each project bid through a combination of BIM components. The total budget estimated in this BIM component equivalent estimation step approximates the total budget in the equivalent analysis step.
