[0028] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, the principles and spirit of the present disclosure will be described with reference to several exemplary embodiments. It should be understood that these embodiments are provided only to enable those skilled in the art to better understand and implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] It should be understood herein that any number of elements in the drawings is for illustration rather than limitation, and any naming is only for distinction rather than having any limiting meaning.

[0030] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not represent any order, quantity or importance, but are only used to distinguish different components.

The article "one" or "a" before an element does not exclude the existence of multiple such elements.

[0031] The principle and spirit of the present disclosure are explained in detail below with reference to several representative embodiments of the present disclosure.

[0032] As described in the background technology, the relevant technologies fail to fully cover all stages of the building's life cycle, such as ignoring carbon emissions during the reconstruction, maintenance and modification stages of the building, and the accounting methods often lack detailed data on carbon emissions at each stage of the building's life cycle, resulting in low accuracy of the accounting results. Specifically, although the international standards ISO14040 and ISO14044 provide basic principles for data collection for carbon footprint accounting, they do not specifically break down into detailed data items for carbon emissions at each stage of the building's life cycle. This leads to certain limitations in the calculation of carbon emissions throughout the building's life cycle in practical applications; especially during the reconstruction, maintenance and modification stages of the building, the carbon emissions at these stages are often ignored, and these stages actually have a significant impact on the overall carbon emissions; therefore, the current accounting methods lack comprehensiveness and fail to fully cover every important link of the building from construction to demolition.

[0033] In the existing practice of building carbon emission accounting, the consideration of the building materials production stage is limited to the new construction stage, while ignoring the reconstruction, maintenance and modification stages that the building may experience during its actual use; the material replacement and maintenance activities involved in these stages will also generate carbon emissions, but they are not fully reflected in the current accounting system; in addition, the accounting of the construction stage is not comprehensive, only considering the energy consumption of mechanical equipment, but not including the carbon emissions corresponding to electricity consumption in the calculation, which further reduces the accuracy of the accounting results.

[0034] During the operation and disposal stages of buildings, the existing accounting methods also show their limitations; the use of renewable energy and the carbon absorption effect of carbon sink systems are not taken into account during the operation stage, which may lead to an underestimation of the actual carbon emissions from building operations; and during the disposal stage, carbon emissions are not differentiated according to different disposal methods (such as demolition, recycling, reuse, etc.). This approach makes it difficult for the final carbon emission accounting results to reflect the true carbon impact of the building's entire life cycle, thereby affecting the accuracy and reliability of the accounting results.

[0035] In order to solve the above problems, the present disclosure provides a building life cycle carbon emission assessment method and related device solutions, specifically including:

[0036] Determine the greenhouse gas emission stage of the building's entire life cycle, identify the greenhouse gas emission stage, and obtain the greenhouse gas emission source; determine the carbon emission coefficient of the greenhouse gas emission source, evaluate the greenhouse gas emission source based on the carbon emission coefficient, and obtain the greenhouse gas emissions of each stage of the greenhouse gas emission stage; summarize the greenhouse gas emissions of each stage to obtain the greenhouse gas emissions of the building's entire life cycle. The present disclosure ensures comprehensive coverage of emission sources by systematically determining and identifying the greenhouse gas emission stages of the building's entire life cycle, including building materials production, building construction, building operation, building maintenance and modification, and building demolition, thereby solving the problem of ignoring carbon emissions in the reconstruction, maintenance and modification stages of buildings in the prior art. At the same time, the present disclosure obtains specific greenhouse gas emissions in each stage by accurately determining the carbon emission coefficient of each emission source and conducting a detailed evaluation of these sources; this method not only provides detailed data on carbon emissions at each stage of the building's life cycle, but also obtains greenhouse gas emissions for the entire life cycle of the building by summarizing these data, significantly improving the accuracy and reliability of the accounting results.

[0037] After introducing the basic principles of the present disclosure, various non-limiting embodiments of the present disclosure are described in detail below.

[0038] refer to Figure 1 , which is a schematic diagram of an application scenario of the building full life cycle carbon emission assessment method provided by the exemplary embodiment of the present disclosure.

[0039] This application scenario includes a terminal device 101 and a server 102. The terminal device 101 and the server 102 may be connected via a wired or wireless communication network to achieve data interaction.

[0040] The terminal device 101 may be an electronic device with data transmission and multimedia input / output functions close to the user side, including but not limited to a desktop computer, a mobile phone, a mobile computer, a tablet computer, a media player, a smart wearable device, a personal digital assistant (PDA) or other electronic devices capable of realizing the above functions. The electronic device may include a processor and a display screen with a touch input function, the display screen is used to present a graphical user interface, the graphical user interface can display an application interface, and the processor is used to process application data, generate a graphical user interface, and control the display of the graphical user interface on the display screen.

[0041] Server 102 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

[0042] In some exemplary embodiments, the building life cycle carbon emission assessment method can be run on the terminal device 101 or the server 102 .

[0043] When the building life cycle carbon emission assessment method is run on the server 102 , the server 102 is used to provide a building life cycle carbon emission assessment service to the user of the terminal device 101 .

[0044] The server 102 determines the greenhouse gas emission stage of the building throughout its life cycle, and the server 102 identifies the greenhouse gas emission stage and obtains the greenhouse gas emission source;

[0045] The server 102 determines the carbon emission coefficient of the greenhouse gas emission source, and the server 102 evaluates the greenhouse gas emission source based on the carbon emission coefficient to obtain the greenhouse gas emission amount of each stage of the greenhouse gas emission stage;

[0046] The server 102 summarizes the greenhouse gas emissions in each stage, and the server 102 obtains the greenhouse gas emissions for the entire life cycle of the building.

[0047] It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principle of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. On the contrary, the embodiments of the present disclosure can be applied to any applicable scenario.

[0048] refer to Figure 2 , a building life cycle carbon emission assessment method, applied to a server, the method comprises the following steps:

[0049] Step S210: determine the greenhouse gas emission stage of the entire life cycle of the building, identify the greenhouse gas emission stage, and obtain the greenhouse gas emission source.

[0050] In this exemplary embodiment, the greenhouse gas emission stage includes: a direct emission stage and an indirect emission stage.

[0051] In specific implementation, the direct emission stage refers to:

[0052] The stage in which greenhouse gas emissions are directly generated during the physical process of construction activities; it includes: the building materials production stage, which refers to the carbon emissions directly generated during the production of building materials; the building materials transportation stage, which refers to the carbon emissions in the process of transporting building materials from the production site to the construction site and the carbon emissions in the process of transporting construction waste from the demolition site to the recycling site, landfill or incineration plant during the building demolition stage; the construction stage, which refers to the carbon emissions generated by the energy consumption of machinery and equipment under different construction methods and the carbon emissions generated by the electricity consumption of lighting equipment required for construction; the building demolition stage, which refers to the carbon emissions generated by the energy consumption of the demolition process.

[0053] In specific implementation, the indirect emission stage refers to:

[0054] Emissions are not directly generated during the physical process of construction activities, but are emissions associated with energy consumption; the building operation stage refers to emissions caused by energy consumption during the use of the building, such as electricity and heat; the building materials disposal stage refers to emissions during the treatment of waste building materials after the building is demolished, such as landfill or incineration.

[0055] In the above exemplary embodiment, the greenhouse gas emission stage is introduced. Now, the greenhouse gas emission sources are introduced:

[0056] In this exemplary embodiment, the greenhouse gas emission sources include: direct emission stage greenhouse gas emission sources and indirect emission stage greenhouse gas emission sources.

[0057] In specific implementation, the sources of greenhouse gas emissions in the direct emission stage refer to:

[0058] Greenhouse gas emissions directly generated from physical activities and processes throughout the life cycle of a building, including raw material processing and manufacturing in the building materials production stage, logistics and transportation activities in the building materials transportation stage, on-site construction operations in the construction stage, and demolition activities in the building demolition stage.

[0059] In specific implementation, the sources of greenhouse gas emissions in the indirect emission stage refer to:

[0060] Emissions that are not directly derived from building physical activities but are related to the energy consumption of buildings mainly include emissions generated by the use of electricity, heat, cooling and other forms of energy during the operation of the building, as well as emissions during waste treatment during the disposal of building materials. These emissions are usually due to greenhouse gas releases during energy production and distribution, rather than directly generated at the building site.

[0061] In the above exemplary embodiments, the greenhouse gas emission sources are introduced. The following describes the method of obtaining the greenhouse gas emission sources:

[0062] In this exemplary embodiment, identifying the greenhouse gas emission stage and obtaining the greenhouse gas emission source includes:

[0063] Identify the greenhouse gas emission sources in the direct emission stage to obtain the greenhouse gas emission sources in the direct emission stage; identify the greenhouse gas emission sources in the indirect emission stage to obtain the greenhouse gas emission sources in the indirect emission stage.

[0064] In specific implementation, the greenhouse gas emission sources in the direct emission stage are identified, and the greenhouse gas emission sources in the direct emission stage are obtained as follows:

[0065] As a specific embodiment, when calculating the greenhouse gas emissions in the building materials production stage, based on the detailed material requirement list of the initial construction of the building project, for each building material, its usage (mass or volume) is multiplied by a specific carbon emission coefficient, and then these products are aggregated to calculate the total carbon emissions related to the production of building materials in different construction stages, from new construction to reconstruction, maintenance and modification; this accounting process is based on in-depth on-site investigations, detailed data analysis and trial calculations of actual cases to ensure that the greenhouse gas emission sources in the building materials production stage can be fully captured, and the impact of these emission sources on the environment is carefully recorded and calculated according to the data items listed in Table 1.

[0066] Table 1 Detailed list of greenhouse gas emission sources in the building materials production stage

[0067]

[0068]

[0069] In construction projects, greenhouse gas emissions generated during the building materials transportation stage are mainly attributed to the energy consumed in transporting building materials from the production site to the construction site, and in transferring the waste generated by demolition from the site to recycling, landfill or incineration facilities; these emissions mainly come from the combustion of fossil fuels and the use of electricity, and it is necessary to consider all energy consumption that contributes significantly to total emissions to ensure that the coverage rate reaches at least 95%; through field visits, in-depth research and trial calculations of actual cases, the key data items that must be included in the calculation of carbon emissions during the building materials transportation stage have been determined. These data items should at least cover the transportation weight, supplier location, construction project location, waste recycling point, landfill and incineration plant location, total transportation distance and transportation method listed in Table 2; such detailed data collection and accounting are essential for accurately assessing the carbon footprint of building materials transportation.

[0070] Table 2 Detailed list of greenhouse gas emission sources in the construction materials transportation stage

[0071]

[0072]

[0073] During the construction phase, greenhouse gas emissions can be mainly attributed to two aspects: one is the energy consumption of various machinery and equipment on the construction site, including but not limited to the combustion of fossil fuels, electricity use and heat consumption; the other is the electricity consumption of lighting facilities during the construction process; in order to fully capture the carbon emissions at this stage, it is necessary to ensure that the accounting covers all major emission sources, that is, those activities that contribute more than 95% of the total emissions. Through field surveys, in-depth analysis and trial calculations based on actual cases, a comprehensive carbon emission accounting framework can be determined, which includes at least all energy consumption data items listed in Table 3, thereby providing a detailed quantitative basis for greenhouse gas emissions during the construction phase.

[0074] Table 3 Detailed list of greenhouse gas emission sources during the construction phase

[0075]

[0076] During the building demolition stage, greenhouse gas emissions are mainly derived from the energy consumed by the processes and equipment used in the demolition process. In order to accurately calculate the carbon emissions at this stage, it is necessary to comprehensively consider the results of field surveys, in-depth research results, and trial calculation data from actual cases. Based on this information, a comprehensive carbon emissions accounting scope can be determined to ensure that at least all key energy consumption data items listed in Table 4 are included. Such an accounting method can provide a detailed and accurate quantitative perspective on greenhouse gas emissions during the building demolition stage, thereby more effectively managing and reducing the impact of demolition activities on the environment.

[0077] Table 4 Detailed list of greenhouse gas emission sources during building demolition phase

[0078]

[0079]

[0080] In specific implementation, the greenhouse gas emission sources in the indirect emission stage are identified, and the greenhouse gas emission sources in the indirect emission stage are obtained as follows:

[0081] Following the above exemplary embodiment, during the operation phase of a building, the calculation of carbon emissions involves multiple emission sources, including emissions from burning fuels, using electricity and refrigerants, and emissions caused by energy consumption of mechanical equipment during building maintenance and renovation. In addition, in order to obtain net carbon emissions, it is necessary to deduct emissions offset by renewable energy systems (such as solar energy and wind energy) and carbon sinks (such as vegetation carbon sequestration) from total emissions. This accounting process needs to be based on on-site investigations, in-depth analysis, and trial calculations of actual cases to ensure the accuracy and completeness of the data. Specifically, the carbon emissions accounting during the operation phase of a building should at least cover the energy consumption listed in Table 5 and the energy generation listed in Table 6.

[0082] Table 5 Detailed list of greenhouse gas emission sources during the building operation phase

[0083]

[0084] Table 6 Detailed list of greenhouse gas emission reduction sources during the building operation phase

[0085]

[0086] During the building waste disposal stage, greenhouse gas emissions mainly come from three key links: first, the energy consumption of equipment required in the recycling and purification process of waste building materials; second, the emissions generated during the incineration of demolished building materials; and finally, the emissions generated when waste building materials are landfilled. In order to fully capture the carbon emissions at this stage, field research, in-depth analysis and trial calculations based on actual cases must be conducted to ensure that at least all key energy consumption data items listed in Table 7 are included.

[0087] Table 7 Detailed list of greenhouse gas emission sources in the building waste disposal stage

[0088]

[0089] Step S220: determine the carbon emission coefficient of the greenhouse gas emission source, evaluate the greenhouse gas emission source based on the carbon emission coefficient, and obtain the greenhouse gas emissions of each stage of the greenhouse gas emission stage.

[0090] In specific implementation, the carbon emission coefficient refers to:

[0091] A specific value is assigned to the emission sources at each stage of the building's life cycle. This value represents the greenhouse gas emissions generated per unit of activity (such as per kilogram of building materials, per liter of fuel, or per kilowatt-hour of electricity consumption). It is used to quantify and calculate the carbon footprint of the environmental impact of a construction project from the production of building materials to its final disposal.

[0092] In specific implementation, the method for determining the carbon emission coefficient of the greenhouse gas emission source is:

[0093] Continuing with the above exemplary embodiments, the carbon footprint factors of the building materials production stage, building materials transportation stage, building construction stage, building operation stage, building demolition stage, and building materials disposal stage are obtained by actual measurement to obtain the carbon emission coefficient of the greenhouse gas emission source, or the carbon emission coefficient of the greenhouse gas emission source is queried in the data in the database, such as the national greenhouse gas emission accounting methods and reporting guidelines for enterprises in 24 industries, China's CLCD database, Switzerland's Ecoinvent database, the United Nations Intergovernmental Panel on Climate Change IPCC database, the EU Emission Factor Database, the US EPA and other general emission factor libraries.

[0094] In the above exemplary embodiment, a method for determining the carbon emission coefficient of the greenhouse gas emission source is introduced. The following is a method for obtaining the greenhouse gas emissions at each stage:

[0095] In this exemplary embodiment, the greenhouse gas emission source is evaluated based on the carbon emission coefficient to obtain the greenhouse gas emissions of each stage of the greenhouse gas emission stage, including:

[0096] The greenhouse gas emissions in each stage include: greenhouse gas emissions in the direct emission stage and greenhouse gas emissions in the indirect emission stage; the greenhouse gas emissions of the greenhouse gas emission sources in the direct emission stage are evaluated based on the carbon emission coefficient to obtain the greenhouse gas emissions in the direct emission stage; the greenhouse gas emissions of the greenhouse gas emission sources in the indirect emission stage are evaluated based on the carbon emission coefficient to obtain the greenhouse gas emissions in the indirect emission stage.

[0097] In specific implementation, greenhouse gas emissions at each stage refer to:

[0098] The total emissions of carbon dioxide and other greenhouse gases generated by various activities such as energy consumption, material use, waste treatment, etc. at each stage of the building's life cycle, including building materials production, building materials transportation, building construction, building operation, building demolition and building materials disposal, are calculated using the corresponding carbon emission factors and activity data to assess the overall impact of the building project on climate change.

[0099] In the above exemplary embodiment, the greenhouse gas emissions in each stage are introduced. The following further introduces a method for evaluating the greenhouse gas emissions of the greenhouse gas emission sources in the direct emission stage based on the carbon emission coefficient to obtain the greenhouse gas emissions in the direct emission stage:

[0102] In specific implementation, the building materials transportation stage of the direct emission stage is determined, and the greenhouse gas emissions of the building materials transportation stage are evaluated based on the carbon emission coefficient. The greenhouse gas emissions of the building materials transportation stage are obtained as follows:

[0103] Following the above exemplary embodiment, the carbon emission accounting of the building materials transportation stage includes the carbon emission during the transportation of building materials from the production site to the construction site and the carbon emission during the transportation of building waste from the demolition site to the recycling site, landfill or incineration plant during the building demolition stage. The greenhouse gas emissions during the building materials transportation stage are calculated as follows:

[0105] Among them, C YS is the greenhouse gas emissions during the transportation of building materials, EF I is the carbon emission factor per unit mass transportation distance under the i-th building material transportation mode, L i is the transportation distance of the i-th building material.

[0106] In specific implementation, the building demolition stage of the direct emission stage is determined, and the greenhouse gas emissions of the building demolition stage are evaluated based on the carbon emission coefficient. The greenhouse gas emissions of the building demolition stage are obtained as follows:

Below, a method for evaluating the greenhouse gas emissions in the building materials production stage based on the carbon emission coefficient to obtain the greenhouse gas emissions in the building materials production stage is further introduced:
