[0002] As a core component of national modernization, engineering plays a fundamental role. my country's engineering construction sector is currently in a critical stage of green and low-carbon transformation. As a basic carrier supporting economic and social development, it is imperative to build a carbon emission accounting system covering the entire industry.

[0003] Life-cycle-based engineering carbon emissions mainly focus on the physicalization and operation and maintenance phases. However, current research primarily concentrates on the operation and maintenance phase, with limited research on carbon emissions during the construction phase. Engineering construction is characterized by its phased nature, making energy consumption statistics relatively complex. The accounting boundaries and accounting entities are not yet clearly defined, making it difficult to construct a comprehensive energy consumption and carbon emission inventory with the construction unit as the responsible party.

[0004] Currently, existing technologies for determining carbon emissions during the engineering construction phase generally employ a manual statistical and decentralized accounting approach. However, due to drawbacks such as complex energy consumption statistics and unclear accounting boundaries and subjects, the accuracy and efficiency of carbon emission accounting results for engineering construction are low. Therefore, improving the efficiency and accuracy of carbon emission accounting for engineering construction is an urgent technical problem to be solved. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

[0029] It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0030] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, step, or component, but does not exclude the presence or addition of one or more other features, elements, steps, or components.

[0031] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection with an intermediary, and can refer not only to a wired connection, but also to a wireless connection. The specific meaning can be changed based on the actual application scenario.

[0032] To address the shortcomings of existing technologies, this invention provides a quota-based method for calculating carbon emissions in engineering construction. This method can collect carbon emission data corresponding to the production, transportation, and construction equipment of engineering construction materials in real time, dynamically monitor the total carbon emissions during the materialization stage of the project, and quickly identify high-carbon emission links. This greatly improves the accuracy and efficiency of carbon emission accounting during the engineering construction stage, optimizes the traditional operation mode that relies on manual statistics and decentralized accounting, and enhances the standardization and intelligence level of green and low-carbon engineering management.

[0033] In the following description, embodiments of the invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0034] Figure 1 This is a flowchart illustrating a quota-based carbon emission calculation method for engineering construction according to an embodiment of the present invention. Figure 1 As shown, the quota-based method for calculating carbon emissions from engineering construction includes at least steps S10 to S60.

[0035] Step S10: Construct a quota management library based on the project budget quota and the construction machinery and equipment shift cost quota. The quota management library includes the building material details and construction equipment details corresponding to various quotas.

[0036] This step involves collecting and organizing quotas from the "Engineering Budget Quotas" of various specialties, and compiling a construction machinery and equipment shift quota management database from the "Construction Machinery and Equipment Shift Cost Quotas". (Reference) Figure 2 As shown, based on the "Engineering Budget Quota", the quota categories can be specifically divided into basic quotas, budget quotas, supplementary quotas, budget quotas, and estimated quotas.

[0037] This step can be implemented based on the quota management module of the carbon emission calculation system, such as... Figure 2 As shown, the quota management module can include basic quotas, budget quotas, supplementary quotas, preliminary quotas, estimated quotas, and construction machinery and equipment shifts for specialties such as water supply and drainage, information, station building equipment, and tunnels. The quota management library includes detailed lists of building materials and construction equipment corresponding to various quotas. These detailed lists provide the basis for carbon emission accounting in subsequent steps. For example, the detailed lists of building materials may include the name of the building material, the unit of measurement, and the unit consumption.

[0038] Step S20: Construct a carbon emission factor database based on the national greenhouse gas emission factor database and carbon emission factor standards, and establish the correlation between various building materials, construction equipment and corresponding carbon emission factors based on the quota management database and the carbon emission factor database.

[0039] This step further involves constructing a carbon emission factor database, which includes various carbon emission factors determined based on the national greenhouse gas emission factor database and carbon emission factor standards. These standards include international standards, national standards, local standards, team standards, industry standards, and literature standards. This step can be implemented using the carbon emission factor database management module of a carbon emission calculation system, such as... Figure 3 As shown, carbon emission factors collected from the National Greenhouse Gas Emission Factor Database and carbon emission factor standards can be categorized into seven types based on their source: National Greenhouse Gas Emission Factor Database, 01 International Standards, 02 National Standards, 03 Local Standards, 04 Team Standards, 05 Industry Standards, and 06 Literature. Each category includes carbon emission factors corresponding to various types such as fuels, production processes, and treatment processes. Furthermore, to ensure the comprehensiveness of the carbon emission factor database, a dynamically updated database can be constructed to support accurate carbon emission calculations at each stage of engineering construction. Missing carbon emission factors in the database can be supplemented and expanded by searching literature.

[0040] Step S30: Obtain the quota required for the engineering construction project, determine the required building materials corresponding to the required quota based on the quota management library, determine the carbon emission factor of the required building materials based on the correlation, and calculate the production carbon emission of the required building materials based on the carbon emission factor.

[0041] In this step, the specific quotas required for the engineering construction project are obtained. Based on the obtained quotas, the corresponding building materials are retrieved from the quota management database. Since there is a correlation between the quota management database and the carbon emission factor database, and between building materials, construction equipment, and corresponding carbon emission factors, after determining the required building materials based on the quota management database, the carbon emission factors of the building materials corresponding to the required building materials can be further determined based on the correlation. Thus, the carbon emissions from the production of the required building materials are calculated based on the carbon emission factors of the building materials.

[0042] This step can be implemented based on the carbon emission accounting module of the carbon emission calculation system. Specifically, the carbon emission accounting module receives the required quotas for the engineering construction project, selects all required quotas from the quota management library, retrieves the specific required building materials from the quota sub-items in the quota management library, and obtains the corresponding building material carbon emission factors from the associated carbon emission factor library, calculating the production carbon emissions. Since the building material details in the quota management library include the building material name, unit of measurement, and unit consumption, retrieving the required quota from the quota management library will also automatically retrieve the building material names, units of measurement, and unit consumption included in the required quota.

[0043] In one embodiment, calculating the carbon emissions of the required building materials based on the building material carbon emission factor includes: obtaining the quantity of the required quota, and calculating the production carbon emissions based on the quantity of the required quota, the building material carbon emission factor, and the unit consumption of the required building materials. In this step, the carbon emission accounting module can also receive the input quantity of the required quota; that is, after inputting the quantity of the required quota, the production carbon emissions of the required building materials can be calculated based on the unit consumption of the required building materials and the required quota quantity.

[0044] For example, the formula for calculating carbon emissions from production can be: ; in, Y represents the unit consumption of building materials required for the i-th type, and Y represents the required quota quantity. This represents the carbon emission factor of building materials required for the i-th type of building materials. This indicates the total number of categories of building materials required.

[0045] Step S40: Obtain the transportation distance and transportation method of the required building materials, determine the transportation carbon emission factor from the carbon emission factor library based on the transportation method, and calculate the transportation carbon emission of the required building materials based on the transportation distance and the transportation carbon emission factor.

[0046] In this step, the carbon emissions from the transportation of building materials are further calculated based on the transportation distance, mode of transport, and the corresponding carbon emission factor for that mode of transport. Specifically, based on the obtained transportation distance and mode of transport, the corresponding carbon emission factor for that mode of transport can be retrieved from a carbon emission factor database.

[0047] This step can be implemented based on the carbon emission accounting module of the carbon emission calculation system. The carbon emission accounting module receives the input transportation distance and mode of transport, selects the transportation carbon emission factor per unit weight from the carbon emission factor library for each mode of transport, and then selects the corresponding required building materials from the quota management library. Next, it calculates the weight of the required building materials. If the unit of measurement for the required building materials is a mass unit, the weight can be directly calculated based on the unit of measurement and the input required quota quantity. If the unit of measurement for the required building materials is not a mass unit (e.g., piece, set, cubic meter, etc.), the weight can be calculated using the system's internal unit conversion module through conversion calculation. Similarly, the weight of the required building materials can also be input, similar to the required quota quantity. In this case, the carbon emission accounting module receives the input required quota quantity and weight.

[0048] In one specific embodiment, calculating the carbon emissions of the required building materials based on the transportation distance and the transportation carbon emission factor includes: calculating the weight of the materials based on the material measurement unit of the required building materials; and calculating the carbon emissions of the required building materials based on the material weight, the required quota quantity, the transportation distance, and the transportation carbon emission factor.

[0049] For example, the formula for calculating carbon emissions from transportation is: ; in, Y represents the material weight required for the i-th type of building materials, and Y represents the required quota quantity. This represents the transportation distance of the building materials required for the i-th type using the j-th transportation mode, which includes road, rail, and waterway. Let represent the carbon emission factor per unit weight and per unit transport distance for the j-th mode of transport. This indicates the total number of modes of transportation.

[0050] Step S50: Based on the quota management library, determine the required construction equipment corresponding to the required quota, determine the energy carbon emission factor corresponding to the required construction equipment based on the correlation, and calculate the construction carbon emission corresponding to the required construction equipment based on the energy carbon emission factor.

[0051] In this step, the required construction equipment corresponding to the required quota is retrieved from the quota management library. Furthermore, based on the correlation between the quota management library and the carbon emission factor library, the energy carbon emission factor corresponding to the required construction equipment is retrieved from the carbon emission factor library, so as to calculate the construction carbon emission corresponding to the construction equipment based on the energy carbon emission factor.

[0052] Specifically, after inputting the required quota, information such as the name of the construction equipment, unit (usually shift), number of operating shifts per unit, fuel type, consumption unit, and fuel consumption per unit shift can be retrieved from the quota management library. In addition, after inputting the quantity of the required quota, the number of operating shifts for each construction equipment can be calculated. The carbon emissions generated by the construction equipment come from the carbon emissions generated by the consumption of fossil fuels or electricity during the use of the construction equipment. Therefore, the corresponding energy carbon emission factor can be selected from the carbon emission factor library for each energy source, and the total construction carbon emissions of the construction equipment can be automatically calculated.

[0053] For example, the formula for calculating carbon emissions from construction can be: ;in, This represents the energy consumption of the construction equipment using type i energy. Represents the energy carbon emission factor of the i-th energy type. This indicates the total number of energy types used in the construction equipment. , This indicates the total number of construction equipment. This represents the energy consumption per shift for the j-th type of construction equipment using the i-th type of energy. Y represents the number of operating shifts of the j-th type of construction equipment using the i-th type of energy, and Y represents the required quota quantity.

[0054] Step S60: Calculate the total physical carbon emissions of the engineering construction project based on the production carbon emissions, transportation carbon emissions, and construction carbon emissions.

[0055] Based on the accounting boundary for carbon emissions during the construction phase, it is known that carbon emissions during the construction period include carbon emissions generated during building material production, building material transportation, and construction equipment phases. In this step, the total materialized carbon emissions of the construction project are further calculated based on the production carbon emissions obtained in step S30, the transportation carbon emissions obtained in step S40, and the construction carbon emissions obtained in step S50. A schematic diagram of the carbon emission accounting interface for the total materialized carbon emissions is shown below. Figure 4 As shown.

[0056] In one embodiment, calculating the total physical carbon emissions of the engineering construction project based on the production carbon emissions, transportation carbon emissions, and construction carbon emissions includes: calculating the sum of the production carbon emissions, transportation carbon emissions, and construction carbon emissions; and using the sum as the total physical carbon emissions of the engineering construction project.

[0057] For example, the total carbon emissions from engineering materials ( The calculation formula for ) is as follows: ;in, Indicates the total carbon emissions from the physical and chemical processes of the project; This indicates the carbon emissions from the production of the required building materials. This indicates the carbon emissions from the transportation of the required building materials. This indicates the carbon emissions of construction equipment.

[0058] As demonstrated by the above embodiments, this quota-based carbon emission calculation method for engineering construction enables automated collection and dynamic monitoring of carbon emission data. By integrating the quota management library and the carbon emission factor library, it solves the problems of low efficiency and large errors in traditional carbon emission accounting methods, improving the accuracy and real-time performance of carbon emission accounting during the engineering construction phase. Furthermore, this method supports precise identification and optimization of carbon emissions throughout the entire process. By linking the quota management library and the carbon emission factor library, it automatically calculates carbon emissions during the material production, transportation, and construction equipment usage phases, quickly identifying high-carbon stages and providing data support for green construction decisions, thus contributing to the standardization of low-carbon engineering management. This method significantly reduces the cost and time of carbon emission accounting. By replacing scattered manual calculations with an intelligent accounting module, it saves substantial human resources and provides an efficient technical tool for setting engineering carbon reduction targets and regulating carbon emissions in the industry.

[0059] Accordingly, this application also discloses a quota-based carbon emission calculation system for engineering construction. The system includes a processor, a memory, and a computer program stored in the memory. The processor is used to execute the computer program. When the computer program is executed, the system implements the steps of the method as described in any of the above embodiments.

[0060] Specifically, a quota-based carbon emission calculation system for engineering construction can realize intelligent and standardized accounting and summarization of carbon emissions during the physicalization stage of engineering projects; for example, it may include a quota management module, a carbon emission factor library management module, and a carbon emission accounting module.

The first type is categorized in the material production carbon emission calculation table, the second type in the material transportation carbon emission calculation table, and the third type in the construction equipment construction carbon emission calculation table. The production carbon emission calculation table is as follows: Figure 7 As shown in the table, the carbon emission calculation for transportation is as follows: Figure 8 As shown in the table, the carbon emission calculation for construction is as follows: Figure 9 As shown.
