[0002] In the field of building engineering construction, carbon emission analysis of building engineering during the construction period is of great significance for achieving sustainable development and carbon neutralization goals. Traditional carbon emission analysis methods mainly focus on carbon emission evaluation of the whole life cycle of buildings, including material production, transportation, construction and use and maintenance stages. However, for the carbon emission analysis during the construction period, the existing methods are mostly based on the estimation of the overall project level, lacking detailed analysis of each work procedure in the construction process. SUMMARY

[0006] Obtain the engineering project information of the target building engineering, and analyze the engineering project information based on the carbon emission calculation boundary to construct a calculation object list, each calculation object in the calculation object list being associated with a corresponding emission category identifier.

[0007] Iterate through each calculation object in the calculation object list, perform carbon emission calculation program matching and application according to the emission category identifier in the preset carbon emission calculation program set, and correspondingly generate carbon emission analysis results.

[0008] In a feasible implementation manner, wherein:

[0009] The emission category identifier included in the engineering construction direct carbon emission is main direct carbon emission and other direct carbon emission.

[0010] The emission category identifier included in the supply chain indirect carbon emission is building material carbon emission and other indirect carbon emission.

[0014] The list of objects to be measured is classified according to the emission category identifier, and the classification results are obtained. The classification results include major direct carbon emissions, other direct carbon emissions, carbon emissions from building materials, and other indirect carbon emissions.

[0015] In the set of carbon emission calculation programs, a corresponding carbon emission calculation program is matched to the classification results, and the main direct carbon emission values, other direct carbon emission values, building material carbon emission values ​​and other indirect carbon emission values ​​are calculated accordingly.

[0023] The carbon emissions of the construction workers and the construction machinery are calculated together, and the carbon emission coefficient under special construction conditions is used to calculate the increased carbon emissions under special construction conditions.

[0037] The above technical solutions will now be described in detail with reference to the accompanying drawings and specific embodiments to provide a better understanding of them. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the present invention is not limited to the exemplary embodiments used only to explain the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Furthermore, it should be noted that, for ease of description, only the parts related to the present invention are shown in the drawings, not all of them.

[0038] Example, Figure 1 This is a flowchart illustrating the carbon emission analysis method for construction projects during the construction period based on work processes according to the present invention. The method includes:

[0039] S100: Defines the boundary for carbon emission measurement based on the transmissibility of carbon emissions.

[0040] Specifically, the carbon emission measurement boundary is used to define the specific scope and inclusion relationships required for carbon emission analysis during the construction period of a building project. Among them, the carbon emission transferability refers to the transfer and accumulation relationship of carbon emissions between various stages of building project construction (such as material production, transportation, construction, etc.).

[0041] Specifically, the process begins by analyzing each stage of carbon emissions during the construction of a building project, identifying which carbon emissions are directly generated from construction activities on-site (direct carbon emissions from construction) and which originate from off-site activities such as the production and transportation of construction materials (indirect carbon emissions from the supply chain). Then, based on the carbon emission transmission paths, the starting and ending points of these carbon emissions during the construction period are determined, thereby establishing the carbon emission measurement boundaries.

[0042] In the overall carbon emission analysis methodology, this step serves to provide a clear scope for subsequent carbon emission data collection and analysis, ensuring the completeness and accuracy of carbon emission calculations. By defining the calculation boundaries based on carbon emission transferability, it is possible to avoid omissions or double counting of carbon emissions, thus improving the systematic nature of carbon emission analysis.

[0043] In some embodiments, the carbon emission measurement boundary includes direct carbon emissions from engineering construction and indirect carbon emissions from the supply chain, wherein:

[0044] The direct carbon emissions from the construction project are categorized as major direct carbon emissions and other direct carbon emissions; the indirect carbon emissions from the supply chain are categorized as carbon emissions from building materials and other indirect carbon emissions.

[0045] Specifically, such as Figure 2 As shown, the carbon emission measurement boundary includes two main parts: direct carbon emissions from construction and indirect carbon emissions from the supply chain. Direct carbon emissions from construction refer to carbon emissions generated at the construction site due to the construction activities themselves, such as the operation of construction machinery and the energy consumption of construction workers. Indirect carbon emissions from the supply chain refer to carbon emissions generated in the upstream and downstream industrial chains related to construction, such as the production and transportation of building materials and the transportation of machinery and equipment.

[0046] Specifically, the emission category labels for major direct carbon emissions correspond to carbon emissions generated by core construction activities at the construction site, which can be considered the main source of carbon emissions. The emission category labels for other direct carbon emissions cover carbon emissions generated by auxiliary construction activities at the construction site other than core construction activities, such as the operating costs of temporary buildings.

[0047] Specifically, the carbon emission category label for building materials corresponds to the primary source of carbon emissions from the production process of building materials. Other indirect carbon emission category labels correspond to carbon emissions generated in other parts of the supply chain besides building material production, such as the transportation of machinery and equipment and purchased electricity.

[0048] By subdividing the carbon emission measurement boundary into direct carbon emissions from engineering construction and indirect carbon emissions from the supply chain, and further subdividing each emission category, the composition and sources of carbon emissions during the construction period of building projects can be clearly displayed. This helps to improve the systematic nature of subsequent carbon emission analysis, making the collection and calculation of carbon emission data more targeted, avoiding data confusion and omissions, and thus enhancing the accuracy of the analysis results.

[0049] In addition, clear emission category classification facilitates the identification of major carbon emission sources, providing more accurate guidance for the subsequent development of targeted carbon reduction measures, and helping to improve the efficiency and effectiveness of carbon emission management.

[0050] S200: Obtain the project information of the target building project, and parse the project information based on the carbon emission calculation boundary to construct a calculation object list. Each calculation object in the calculation object list is associated with a corresponding emission category identifier.

[0051] Specifically, project information comes from various data and materials related to construction projects, such as design drawings, construction plans, material lists, equipment usage, and personnel allocation.

[0052] Specifically, the list of objects to be measured is a list of all engineering activities or elements that need to be calculated for carbon emissions, and each object to be measured is clearly identified by its emission category, which includes: main direct carbon emissions, other direct carbon emissions, carbon emissions from building materials, or other indirect carbon emissions.

[0053] Specifically, first, detailed project information for the target construction project is collected, including but not limited to construction schedules, material procurement lists, construction equipment ledgers, and construction personnel lists. Then, based on defined carbon emission measurement boundaries, this information is filtered and categorized to separate information related to direct carbon emissions from construction from information related to indirect carbon emissions from the supply chain. Next, each project activity or element is treated as a measurement object, and a corresponding emission category label is assigned to it based on its carbon emission source and nature, thus constructing a list of measurement objects.

[0054] In the overall carbon emission analysis methodology, the steps described above serve to prepare a precise and clearly categorized data foundation for subsequent carbon emission calculations, ensuring that the carbon emissions of each measurement object can be accurately calculated and classified. Accurate analysis and classification based on the carbon emission measurement boundaries ensures the high accuracy and completeness of the data upon which the carbon emission calculations are based, thereby enhancing the reliability of the analysis results. Constructing a detailed list of measurement objects and associating it with emission category identifiers facilitates refined management of carbon emission data, improves the systematic nature of carbon emission analysis, and makes it easier to accurately calculate and summarize the carbon emissions of each measurement object in subsequent steps.

[0055] In some embodiments, the list of measurement objects includes at least:

[0056] Earthwork engineering, foundation treatment and slope protection engineering, pile foundation engineering, masonry engineering, concrete and reinforced concrete engineering, metal structure engineering, door and window engineering, roofing and waterproofing engineering, thermal insulation and anti-corrosion engineering, floor and ground decoration engineering, wall and column decoration and partition curtain wall engineering, ceiling engineering, painting and wallpapering engineering, other decoration engineering, temporary facilities projects, and temporary building operation consumption.

[0057] For example, the list of measurement objects is shown in Table 1 below:

[0058] Table 1. List of exemplary measurement objects

[0059]

[0060] S300: Traverse each measurement object in the measurement object list, perform carbon emission measurement program matching and application in the preset carbon emission measurement program set according to the emission category identifier, and generate corresponding carbon emission analysis results.

[0061] Specifically, each measurement object in the measurement object list contains one or more measurement items that need to be measured. By comprehensively checking and processing each engineering activity or element in the measurement object list in sequence, the specific items that need to be measured can be identified, and then a suitable measurement program (and modular standard measurement method) can be selected to perform carbon emission analysis and calculation. Among them, the preset carbon emission measurement program set is a collection of carbon emission calculation methods and models pre-defined according to emission categories.

[0062] Specifically, first, each measurement object in the list is categorized according to its emission category. Then, a measurement program matching the emission category is found in a pre-set set of carbon emission measurement programs. For example, for measurement objects with major direct carbon emissions, such as the use of construction machinery, a program for calculating the carbon emissions of construction machinery will be invoked; for measurement objects with carbon emissions from building materials, a program for calculating the carbon emissions from the production and transportation of building materials will be invoked.

[0063] Furthermore, after matching the corresponding calculation program, the relevant data of the calculation object are substituted into the program for calculation to ensure the relevance and accuracy of carbon emission calculation, making the final carbon emission analysis results more reliable.

[0064] Throughout the carbon emissions analysis process, the above steps serve to accurately calculate the carbon emissions of each target through automated matching and calculation, thereby providing basic data for subsequent total carbon emissions aggregation and analysis.

[0065] For example, the aforementioned set of preset carbon emission calculation procedures can be represented as shown in Table 2 below:

[0066] Table 2. A collection of exemplary carbon emission calculation procedures

[0067]

[0068] In some embodiments, each measurement object in the measurement object list is traversed, and carbon emission measurement program matching and application are performed in a preset carbon emission measurement program set according to the emission category identifier, including:

[0069] The list of objects to be measured is classified according to the emission category identifier to obtain the classification results. The classification results include major direct carbon emissions, other direct carbon emissions, building material carbon emissions, and other indirect carbon emissions. In the carbon emission measurement program set, a corresponding carbon emission measurement program is matched for the classification results, and the major direct carbon emission values, other direct carbon emission values, building material carbon emission values, and other indirect carbon emission values ​​are calculated accordingly.

[0070] Specifically, firstly, based on the emission category identifier associated with each measurement object, it is categorized into the corresponding emission category. The classification results are: main direct carbon emissions, other direct carbon emissions, building material carbon emissions, or other indirect carbon emissions. Then, a preset set of carbon emission measurement programs is used to match the corresponding carbon emission measurement programs for each of the above four categories.

[0071] For example, for the category of primary direct carbon emissions, the matching program calculates the carbon emissions of construction machinery based on parameters such as the machine-hour consumption, energy consumption, and carbon emission factors of that energy source. For the category of building material carbon emissions, the matching program calculates the carbon emissions from building material production and transportation based on material consumption, carbon emission factors from material production, and carbon emission factors from material transport distance. Then, it calculates the primary direct carbon emission values, other direct carbon emission values, building material carbon emission values, and other indirect carbon emission values.

[0072] The above steps, through classification and matching, enable accurate calculation of different types of carbon emissions, thus providing detailed and accurate basic data for subsequent total carbon emission aggregation and analysis. This classification-based calculation method can employ the most suitable calculation methods and parameters for the characteristics of different emission categories, thereby improving the accuracy of the calculations.

[0073] Meanwhile, categorized calculation helps break down the complex carbon emission calculation process into several relatively simple smaller tasks, reducing computational difficulty and improving efficiency. Furthermore, the various carbon emission values ​​obtained from categorized calculations clearly demonstrate the composition and sources of carbon emissions, facilitating in-depth analysis and interpretation of the results and providing more detailed and valuable data support for developing targeted carbon reduction measures.

[0074] In some implementations, the carbon emission analysis method for construction projects based on work processes during the construction period also includes:

[0075] Based on the main direct carbon emission categories, calculate the carbon emissions of construction workers and construction machinery; calculate the sum of the carbon emissions of construction workers and construction machinery, and combine it with the carbon emission coefficient for special construction conditions to calculate the increased carbon emissions under special construction conditions; take the sum of the carbon emissions of construction workers, the carbon emissions of construction machinery, and the increased carbon emissions under special construction conditions, and output it as the main direct carbon emission value.

[0076] For example, carbon emissions from construction workers should be calculated using the following formula:

[0077] C ry =P×F p ;

[0078] Among them, C ry— Carbon emissions from construction workers (kg CO2); P — Labor consumption for the project (man-days); F p — Carbon emission factor of energy consumption by construction workers (kg CO2 / man-day).

[0079] For example, carbon emissions from construction machinery should be calculated using the following formula:

[0080]

[0081] Where: C jx —Carbon emissions from construction machinery (kg CO2); J i —Consumable quantity (per shift) of the i-th type of construction machinery; F e,i — Carbon emission factor of the i-th type of construction machinery (kg CO2 / shift); i — serial number of the type of construction machinery driven by fossil energy.

[0082] For example, carbon emissions under special construction conditions are calculated using the following formula:

[0083]

[0084] Among them, C tj —Carbon emissions (kg CO2) under special construction conditions; α tj,q —Calculation factor for carbon emissions under special construction conditions, item q; t q — Construction duration under the special construction conditions of item q; t — Total construction time; q — Special construction condition type number.

[0085] In some implementations, the carbon emission analysis method for construction projects based on work processes during the construction period also includes:

[0086] Calculate the carbon emissions consumed during the operation of temporary buildings based on the other direct carbon emission categories, and output them as the other direct carbon emission values.

[0087] For example, the carbon emissions from the operation of temporary construction buildings are calculated using the following formula:

[0088] C0=A×t0×L×F dl ;

[0089] Wherein, C0 represents carbon emissions from the operation of temporary buildings (kg CO2); A represents the area of ​​temporary buildings (m²). 2 ); t0—Temporary building operation time (in years); L—Electricity consumption per unit area of ​​temporary building [kWh / (m²)] 2 ·a)];F dl —Grid carbon emission factor (kg CO2 / kWh).

[0090] In some implementations, the carbon emission analysis method for construction projects based on work processes during the construction period also includes:

[0091] Based on the carbon emission categories of building materials, calculate the carbon emissions from building material production and building material transportation; calculate the sum of the carbon emissions from building material production and building material transportation, and output the carbon emission value of building materials.

[0092] For example, carbon emissions from building material production are calculated using the following formula:

[0093]

[0094] Among them, C jcsc —Carbon emissions during the building materials production stage (kg CO2); M i —Consumption of the i-th major building material; F m,i — Carbon emission factor of the i-th main building material (kg CO2 / building material consumption); i — Serial number of the building material used in construction.

[0095] For example, carbon emissions from the transportation of building materials are calculated using the following formula:

[0096]

[0097] Wherein: C jcys —Carbon emissions during the transportation of building materials (kg CO2); M i — Consumption of the i-th main building material (t); d m,i —Transportation distance (km) for the i-th type of building material; F t,i —Carbon emission factor of the i-th building material during transportation [kg CO2 / (t·km)]; i —Serial number of the building material to be transported.

[0098] In some implementations, the carbon emission analysis method for construction projects based on work processes during the construction period also includes:

[0099] Based on the other indirect carbon emission categories, calculate the carbon emissions from the transportation of machinery and equipment and the carbon emissions from purchased electricity; calculate the sum of the carbon emissions from the transportation of machinery and equipment and the carbon emissions from purchased electricity, and output the other indirect carbon emission value.

[0100] For example, carbon emissions from the transportation of machinery and equipment are calculated using the following formula:

[0101]

[0102] Wherein: C jcsc —Carbon emissions during the building materials production stage (kg CO2); M i —Consumption of the i-th major building material; Fm,i — Carbon emission factor of the i-th main building material (kg CO2 / building material consumption); i — Serial number of the building material used in construction.

[0103] For example, the carbon emissions from purchased electricity are calculated using the following formula:

[0104]

[0105] Among them, C dl — Carbon emissions from purchased electricity (kg CO2); J dl,i — Consumption of the i-th type of electrical equipment per shift (per shift); D dl,i —Electricity consumption per shift for the i-th type of electrical equipment (kWh / shift); F dl —Grid carbon emission factor (kgCO2 / kWh); i —Equipment serial number.

[0106] In some embodiments, such as Figure 3 As shown, the corresponding carbon emission analysis results also include:

[0107] The main direct carbon emission values ​​are summed with the other direct carbon emission values ​​to obtain the direct carbon emission amount of the engineering construction; the carbon emission values ​​of the building materials are summed with the other indirect carbon emission values ​​to obtain the indirect carbon emission amount of the supply chain; the direct carbon emission amount of the engineering construction is summed with the indirect carbon emission amount of the supply chain to obtain the carbon emission amount of the building construction period; the main direct carbon emission values, the other direct carbon emission values, the building material carbon emission values, the other indirect carbon emission values, the direct carbon emission amount of the engineering construction, the indirect carbon emission amount of the supply chain, and the carbon emission amount of the building construction period are output as the carbon emission analysis results.

[0108] Specifically, the above steps involve classifying and summarizing the aforementioned carbon emission values ​​to form a complete carbon emission analysis result for the construction period of a building project. Among them, the direct carbon emissions from construction are the sum of major direct carbon emissions and other direct carbon emissions; the indirect carbon emissions from the supply chain are the sum of carbon emissions from building materials and other indirect carbon emissions; the sum of the two is the carbon emissions during the construction period of the building project.

[0109] The above steps serve to summarize and integrate various types of carbon emissions in the overall carbon emission analysis method, combining scattered carbon emission data into a comprehensive and systematic analysis result. This allows users or stakeholders to intuitively understand the carbon emission situation during the construction period of a building project, providing comprehensive data support for subsequent carbon emission management decisions.

[0110] In summary, the carbon emission analysis method for construction projects based on construction processes provided by this invention has the following technical advantages:

[0111] By defining the carbon emission measurement boundary based on the transitivity of carbon emissions, the system acquires project information of the target building project and performs structured parsing of the project information according to the carbon emission measurement boundary to construct a measurement object list. Each measurement object in the measurement object list is associated with an emission category identifier. The system then iterates through each measurement object in the measurement object list and matches and calls the measurement process in a preset carbon emission measurement program set according to its emission category identifier to complete the carbon emission calculation and output the corresponding carbon emission analysis results. This achieves the technical effects of improving the systematic nature of carbon emission analysis, enhancing the accuracy of analysis results, and improving calculation efficiency.
