Description

Technical Field

[0001] The present application relates to the technical field of carbon emission measurement, and in particular to a method and device for quantitatively measuring the embodied carbon of a building based on the entire life cycle. Background Art

[0002] As the concept of energy conservation and environmental protection continues to deepen, buildings account for at least 39% of global energy-related carbon emissions each year, and at least a quarter of these carbon emissions come from embodied carbon. Therefore, how to scientifically and quantitatively measure the embodied carbon in buildings and then reduce the emissions of embodied carbon in buildings has gradually become the focus of the construction industry to achieve energy conservation and emission reduction.

[0003] At present, the main method for quantitatively measuring the embodied carbon in buildings is to determine the types of building materials contained in the building, and then look for the same type of building materials in the national standard "Building Carbon Emission Calculation Standard". Since the "Building Carbon Emission Calculation Standard" records the carbon emission impact factors and standard values ​​of various types of building materials, the carbon emission impact factors and standard values ​​of each building material corresponding to the building that needs to be quantitatively measured can be found in the "Building Carbon Emission Calculation Standard". Then, the standard value corresponding to the carbon emission impact factor of each building material is multiplied by the volume of the corresponding building material, and then added together to obtain the quantitative measurement result of the building's embodied carbon.

[0004] However, in the national standard "Building Carbon Emission Calculation Standard", it may sometimes be impossible to accurately lock onto a specific model of building materials products, which will affect the accurate measurement of the embodied carbon content of each building materials product in the building, thereby reducing the accuracy of the quantitative measurement of the embodied carbon in the building. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a method and device for quantitatively measuring the embodied carbon in buildings based on the entire life cycle, so as to improve the accuracy of the quantitative measurement of the embodied carbon in buildings.

[0013] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0014] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0015] At present, the quantitative measurement of embodied carbon in buildings is mainly carried out through the "Building Carbon Emission Calculation Standard", which finds various carbon emission factors of buildings in the standard and then calculates the embodied carbon quantitative value of buildings based on these carbon emission factors. However, sometimes it may not be possible to accurately lock in a specific model of building materials products in the standard, resulting in a decrease in the accuracy of the quantitative measurement results of embodied carbon in buildings.

[0016] After research, the inventors found that if buildings can be broken down into a variety of building materials and the corresponding standards are referred to in each stage of the building materials' life cycle, such as production, construction, use, and end of life, the embodied carbon of the building can be quantified. Then, if the upstream supplier provides product carbon footprint or carbon label values, the carbon emission factor issued by a third-party appraisal agency provided by the upstream supplier shall be used first. If the upstream provider does not provide it, the carbon emission factor of the "Building Carbon Emission Calculation Standard" or the carbon emission factor of similar products can be used, which can also more accurately obtain the quantitative measurement value of the building's embodied carbon.

[0017] In view of this, the embodiment of the present application provides a method and device for quantitatively measuring the embodied carbon in buildings based on the entire life cycle, which subdivides the target building into various target building materials, and determines the various materials and their processing processes of each target building material in the production stage, construction stage, use stage and end-of-life stage. After the target building is subdivided, the embodied carbon is quantitatively measured, and then the carbon emission factor of each material and its processing process is determined in the order of the same products and similar products in the "Building Carbon Emission Calculation Standard" issued by a third-party appraisal agency and provided by upstream suppliers, so that the determination of each carbon emission factor is more accurate and rapid, and then the determined carbon emission factors are calculated with the actual amount of the corresponding materials or processes, so that the embodied carbon quantitative measurement results of the building's entire life cycle can be obtained quickly and accurately, thereby improving the accuracy of the building's embodied carbon quantitative measurement results.

[0018] First, the method for quantitatively measuring the embodied carbon in buildings based on the entire life cycle provided in the embodiments of the present application is described in detail.

[0019] Figure 1 This is a flow chart of the method for quantitatively measuring the embodied carbon in buildings based on the entire life cycle in the embodiment of this application, see Figure 1 As shown, the method may include:

[0020] S101: Determine target building materials included in the target building.

[0021] The target building here is the building that needs to be quantitatively measured for embodied carbon throughout its life cycle. To build a target building, a variety of building materials are needed and certain treatments are performed. These building materials are the target building materials.

[0022] In the process of determining the target building materials included in the target building, the number of building materials included in the target building is determined. In other words, the target building materials are determined according to the actual types of building materials in the target building, and no specific limitation is made here.

[0023] S102: Obtain the materials and their processing processes involved in the production stage, construction stage, use stage and end-of-life stage of the target building materials.

[0024] Among them, the materials and their processing processes are the raw materials and related behaviors used in producing target building materials, building target buildings, maintaining target buildings and demolishing target buildings during the production stage, construction stage, use stage and end of life stage.

[0025] The target building materials will have different materials and processing processes involved in different life stages. In the production stage, the materials involved are some raw materials for producing building materials, and the processing process is the transportation of raw materials and the process of processing them into building materials. In the construction stage, the materials involved are the materials and equipment required to build the building materials into buildings, and the processing process is the transportation and construction of materials and equipment. In the use stage, the materials involved are the items for maintaining the building, and the processing process is the transportation and use of these items. In the end-of-life stage, the materials involved are some building materials that are dismantled and reused, and the processing process is the dismantling and reuse of these building materials.

[0026] S103: Calculate the carbon emission factors of each material and its processing process with the corresponding actual quantity in the order of first issued by a third-party appraisal agency and provided by upstream suppliers, then the same products in the "Building Carbon Emission Calculation Standard", and then similar products in the "Building Carbon Emission Calculation Standard" to obtain the quantitative measurement results of the embodied carbon of the target building throughout its life cycle.

[0027] After obtaining the materials and processing involved in each life stage of the target building materials, for each material and its processing involved in each life stage, determine its consumption and carbon emission factor. To determine the carbon emission factors of each material and its processing, first check whether there is a product carbon footprint or carbon label value issued by a third-party certification agency provided by the upstream supplier. If so, use the one provided by the upstream supplier. If not, look for the same product in the "Building Carbon Emission Calculation Standard". If there is no same product, look for similar products. Similar products can be found by looking for adjacent products in the same category or by looking for products with similar names. After obtaining the carbon emission factors of each material and its processing, the carbon emission factors of each material and its processing can be multiplied by the corresponding actual amount, and then added together to obtain the quantitative measurement results of the implicit carbon of the target building throughout its life cycle.

[0028] In practical applications, the "Building Carbon Emission Calculation Standard" can be specifically "Building Carbon Emission Calculation Standard" GB / T51366. Of course, in the subsequent process, the standard will continue to be updated, and the standard used for calculation here can be the latest standard. There is no limitation on the specific version of the standard.

[0029] It can be seen from the above content that the quantitative measurement method of building embodied carbon based on the entire life cycle provided in the embodiment of the present application subdivides the target building into various target building materials, and determines the various materials and their processing processes of each target building material in the production stage, construction stage, use stage and end of life stage. After the target building is subdivided, the embodied carbon is quantitatively measured, and then the carbon emission factor of each material and its processing process is determined in the order of the same product and similar products in the "Building Carbon Emission Calculation Standard" issued by a third-party appraisal agency and provided by upstream suppliers, so that the determination of each carbon emission factor is more accurate and rapid, and then the determined carbon emission factors are calculated with the actual amount of the corresponding material or process, so that the embodied carbon quantitative measurement results of the building's entire life cycle can be obtained quickly and accurately, thereby improving the accuracy of the building embodied carbon quantitative measurement results.

[0030] Furthermore, as a refinement of the above step S102, the target building materials involve not only raw materials but also some energy for processing the raw materials during the production stage. Both raw materials and energy will generate embodied carbon during their acquisition, transportation and processing.

[0031] Specifically, the production stage in the above step S102 may include:

[0032] Step A1: Determine the raw materials and energy involved in the production stage of the target building materials.

[0033] To produce the target building materials, not only raw materials but also energy are needed.

[0034] Step A2: Identify the use of raw materials and energy in the acquisition, transportation and product production stages.

[0035] During the production stage, raw materials and energy are not created out of thin air, but need to be acquired and transported to the production site before they can be processed and produced. Therefore, the processing of raw materials and the use of energy in the production stage are further subdivided into the acquisition stage, transportation stage and product production stage.

[0036] Step A3: Take raw materials and energy and their various usage processes as the materials and their processing processes involved in the production stage of the target building materials.

[0037] The use of raw materials and energy during the acquisition, transportation and product production stages will generate embodied carbon. Therefore, raw materials, energy and their various usage processes are taken as the materials and their processing processes involved in the production stage of target building materials, and the embodied carbon is calculated in accordance with the standards.

[0038] Specifically, the above step A2 may include:

[0039] Step A21: In the acquisition phase, determine the mining process, processing process of raw materials, and pretreatment process of raw materials that replace raw materials, and determine the mining process, processing process of energy, and pretreatment process of fuel that replaces energy.

[0040] Raw materials and energy can only be obtained after mining and processing. When raw materials are scarce or insufficient, the raw materials can be pre-treated to replace the materials. Similarly, when energy is scarce or insufficient, fuels can be pre-treated to replace energy. The above mining, processing, and pre-treatment processes will produce embodied carbon, so these processes need to be calculated into the embodied carbon value according to the standard.

[0041] Step A22: In the transportation phase, determine the transportation process of raw materials and energy from the extraction site to the production site.

[0042] Raw materials and energy are obtained at the mining site, and raw materials and energy must undergo certain processing at the production site before they can be generated into building materials. The transportation of raw materials and energy from the mining site to the production site will also produce embodied carbon during this transportation process. Therefore, this transportation process must also be calculated into the embodied carbon value according to the standard.

[0043] In practical applications, the above-mentioned production site may refer to a factory that produces building materials.

[0044] Step A23: During the product production phase, determine the production process of raw materials from entering the production site to leaving the production site, and determine the transportation process of raw materials and energy within the production site.

[0045] After the raw materials and energy are transported to the production site, they are not processed all at once. Instead, they need to be processed in batches and in different production processes. In this way, the raw materials and energy need to be transported back and forth in the production site. The production and transportation process of raw materials and energy in the production site will produce embodied carbon. Therefore, these production and transportation processes need to be calculated into the embodied carbon value according to the standard.

[0046] From the above content, it can be seen that in the production stage of the target building materials, the target building materials are subdivided into the acquisition stage, the transportation stage and the product production stage, and the specific processing processes of the target building materials are further subdivided in each subdivided stage, so that the embodied carbon generated by the target building materials in the production stage can be fully counted, thereby improving the accuracy of the statistics of the embodied carbon of the target building materials in the production stage, and then improving the accuracy of the quantitative measurement of the embodied carbon of the target building.

[0047] Furthermore, as a refinement of the above step S102, the target building materials during the construction phase involve not only the products but also the construction equipment for processing the products. Both the products and the construction equipment will generate embodied carbon during transportation and construction.

[0048] Specifically, the construction phase in the above step S102 may include:

[0049] Step B1: Determine the construction products and equipment involved in the construction phase of the target building materials.

[0050] The target building materials are used to manufacture the target building, which not only produces products but also requires construction equipment for construction and manufacturing.

[0051] Step B2: Determine the transportation process and construction process of construction products and construction equipment.

[0052] The products manufactured by the target building materials through construction equipment, as well as the construction equipment, are not fixed at the construction site, but need to be moved accordingly according to actual project needs. Whether it is the movement process of the products and construction equipment, or the construction process of the products and construction equipment, embodied carbon will be generated.

[0053] Step B3: Take the construction products and construction equipment as well as their transportation process and construction process as the materials and their processing processes involved in the construction phase of the target building materials.

[0054] Since embodied carbon will be generated during the transportation and construction of products and construction equipment during the construction phase, it is necessary to take the products and construction equipment as well as their transportation and construction processes as the materials and their handling processes involved in the construction phase of the target building materials, and calculate the embodied carbon in accordance with the standards.

[0055] Specifically, the above step B2 may include:

[0056] Step B21: Determine the transportation process of construction products and construction equipment from the production site to the construction site, the transportation process of construction equipment in and out of the construction site, the production, transportation and waste management process of damaged products and materials during transportation, the construction and installation process of construction products, the storage process of construction products, the transportation process of related materials, construction products, waste and construction equipment within the construction site, temporary works related to the construction of construction products and equipment, the production and transformation process of construction products at the construction site, the environmental control process related to the construction of construction products and equipment, the auxiliary materials related to the construction of construction products and equipment, the water related to the construction of construction products and equipment, the management process of waste generated during the construction of construction products and equipment, and the production, transportation and waste management process of lost products and materials during the construction of construction products and equipment.

[0057] Among them, the process of transporting products and construction equipment from the production site to the construction site can include various modes of transportation, storage processes and deployment processes. Construction equipment can include cranes, scaffolding, etc. All impacts and aspects related to transportation losses mainly include the production, transportation and waste management of products and materials damaged during transportation. The construction and installation process of products can include earthwork and landscaping. The storage of products can include the control of the storage environment (for example: heating, refrigeration, humidity control, etc.). Temporary works can include off-site temporary works required for the construction and installation process. Environmental control can include heating, refrigeration, humidity control, etc. Auxiliary materials can be materials that are not calculated in the Environmental Product Declaration (EPD) when installing building materials into buildings, such as: release agents for concrete formwork, formwork discarded at the end of the project, etc. Water related to the construction of products and equipment can be water used for cooling construction machinery and cleaning on site.

[0058] From the above content, it can be seen that during the construction phase of the target building materials, the embodied carbon calculation of all construction processes of the products and construction equipment involved in the construction of the target building materials can fully count the embodied carbon generated by the target building materials during the construction phase, improve the accuracy of the statistics of the embodied carbon of the target building materials during the construction phase, and then improve the accuracy of the quantitative measurement of the embodied carbon of the target building.

[0059] Furthermore, as a refinement of the above step S102, after the target building materials are constructed into the target building, various maintenance matters carried out on the target building during the use phase will also generate embodied carbon.

[0060] Specifically, the use phase in the above step S102 may include:

[0061] Step C1: Determine at least one of a maintenance process, a repair process, a component replacement process, and a renovation process of a target building constructed with target building materials.

[0062] After the target building is constructed using the target building materials, the target building can be put into use. During the use phase of the target building, if there are certain problems with the target building, such as aging of the building, damage to components inside the building, etc., these problems need to be dealt with. Generally speaking, there are four main processes that will generate embodied carbon, namely maintenance process, repair process, component replacement process and renovation process. Therefore, it is necessary to calculate the embodied carbon generated by these four processes during the use phase of the target building. The embodied carbon generated by the maintenance process is relatively small and can be almost ignored.

[0063] Specifically, the above step C1 may include:

[0064] Step C11: Determine the production and transportation process of components and auxiliary products used for maintenance of the target building, the cleaning process inside and outside the target building, and the overall process of maintaining the building's fabric, the functionality and performance of the integrated technical systems, and the aesthetics of the internal and external components.

[0065] The cleaning process here may refer to all cleaning processes inside and outside the target building.

[0066] Step C12: Determine the production, transportation and repair process of the components and auxiliary products used for the renovation of the target building, the treatment process of the waste after the renovation, and the end-of-life stage of the parts removed during the renovation of the target building.

[0067] The components here may refer to the damaged components in the target building that can be restored to use after repair, while the auxiliary products may be the materials or tools used to repair the components.

[0068] Step C13: Determine the production, transportation and replacement process of the parts and auxiliary products used for replacement of the target building, the waste management process and end-of-life stage of the parts and auxiliary products removed during the replacement of the target building.

[0069] The components here may refer to the damaged components in the target building that cannot be restored to use after repair, while the auxiliary products may be the materials or tools used to replace the components.

[0070] Step C14: Determine the production and transportation process of new parts for renovation of the target building, the production process of materials lost in the transportation of new parts, the process of materials lost in the renovation of the target building, the management process of waste generated in the renovation of the target building, and the end-of-life stage of new parts.

[0071] During the transportation of new parts, the production process can include any materials lost in transportation. Materials lost during the renovation of the target building have been carried out. This part of the construction process can include any materials lost during the production renovation.

[0072] From the above content, it can be seen that during the use stage of the target building materials, the embodied carbon calculation of various specific use processes involved in the use of the target building materials can fully count the embodied carbon generated by the target building materials during the use stage, improve the accuracy of the statistics of the embodied carbon of the target building materials during the use stage, and then improve the accuracy of the quantitative measurement of the embodied carbon of the target building.

[0073] Furthermore, as a refinement of the above step S102, after the target building is no longer in use, the target building will be demolished or other treatments will be carried out, and the demolition or other treatments will also generate embodied carbon.

[0074] Specifically, the end-of-life phase in step S102 may include:

[0075] Step D1: Determine the demolition process, waste transportation process, and waste recycling process of the target building constructed with the target building materials.

[0076] If the target building can no longer be used, it will be demolished, and embodied carbon will be generated during the demolition of the target building. After the demolition of the target building, the demolition waste cannot be left on the spot, but needs to be transported to a designated location. The waste transportation process will also generate embodied carbon. Among the waste from the demolition of the target building, some waste can be recycled, and the waste recycling process will also generate embodied carbon. Therefore, it is necessary to calculate the embodied carbon in the demolition, waste transportation, and waste reuse processes of the target building.

[0077] Specifically, the above step D1 may include:

[0078] Step D11: Determine the on-site operation process and off-site operation process of demolishing the target building.

[0079] On-site operations here may refer to all demolition operations carried out at the location of the target building. Off-site operations may refer to the demolition of building parts that cannot be demolished on-site at other locations, or the preparation for demolition, etc.

[0080] Step D12: Determine the transportation process of the waste after the demolition of the target building to the storage site and the treatment site.

[0081] The transportation here may refer to transporting the waste from the immediate storage / treatment site, or transporting the waste to a possible immediate storage / treatment site. The so-called immediate storage / treatment site may refer to a place where the waste is temporarily stored or treated, not the place where the waste finally arrives. Among the demolished materials of the target building, some of the demolished materials cannot be recycled, that is, waste, so the transportation process at this time needs to include the entire transportation process of the waste.

[0082] Step D13: Determine the recycling and reuse process of materials after the target building is demolished.

[0083] After the target building is demolished, a portion of the demolished materials can be recycled and reused, and these demolished materials can be recycled materials, products or building structures, etc. The specific form of the demolished materials that can be recycled and reused is not limited here.

[0084] From the above content, it can be seen that at the end-of-life stage of the target building materials, the embodied carbon in the processes of demolition, waste transportation, waste recycling and various detailed operations of the target building materials are calculated, which can fully count the embodied carbon generated by the target building materials at the end-of-life stage, improve the accuracy of the statistics of the embodied carbon of the target building materials at the end-of-life stage, and then improve the accuracy of the quantitative measurement of the embodied carbon of the target building.

[0085] Furthermore, as an extension of the above step S103, in addition to calculating and measuring the embodied carbon of the target building materials based on the production stage, construction stage, use stage and end-of-life stage, the target building materials are sometimes reconstructed, and the target building materials can offset carbon emissions during the reconstruction stage.

[0086] Specifically, before the above step S103, the method may further include:

[0087] Step E1: Obtain the quantitative measurement results of the embodied carbon of the target building materials during the reconstruction stage.

[0088] Reconstruction refers to adjusting the target building materials so that they have more functional uses or better performance. During the reconstruction phase, the performance of the target building materials is expanded, which will have a more positive effect on the carbon emissions of the target building materials. Therefore, it is also necessary to obtain the quantitative measurement results of the embodied carbon of the target building materials during the reconstruction phase.

[0089] It should be noted here that the reconstruction stage of building materials is not taken into account in the embodied carbon calculation of the building model, but the reconstruction stage of building materials only needs to be considered in actual projects.

[0090] Accordingly, the above step S103 may include:

[0091] Step E2: According to C lc =C sc +C sg +C sy +C cc -C cg , calculate the quantitative measurement results of the embodied carbon over the entire life cycle of the target building.

[0092] Among them, C lc The embodied carbon quantitative measurement results of the target building throughout its life cycle, C sc is the quantitative measurement result of the embodied carbon in the production stage of the target building materials, C sg is the quantitative measurement result of the embodied carbon in the construction stage of the target building materials, C sy is the quantitative measurement result of the embodied carbon in the use phase of the target building, C cc The embodied carbon quantitative measurement result at the end of life of the target building, C cg Quantify the embodied carbon measurements during the reconstruction phase of the target building materials.

[0093] It should be noted here that the "Building Carbon Emission Calculation Standard" can be GB / T 51366. When the standard is updated, the latest standard can be used. The embodied carbon quantitative measurement results or carbon emissions can be measured in tCO 2 e indicates.

[0094] From the above content, it can be seen that when calculating and measuring the embodied carbon of the target building, the embodied carbon of the target building materials in the reconstruction stage can make the actual emissions of the embodied carbon of the target building more detailed, thereby improving the accuracy of the quantitative measurement of the embodied carbon of the target building.

[0095] Furthermore, as a refinement of the above step E1, the quantitative measurement results of the embodied carbon of the target building materials in the reconstruction stage can be obtained through the "Building Carbon Emission Calculation Standard" and combined with a certain calculation method.

[0096] Specifically, the above step E1 may include:

[0097] Step E11: According to , according to the "Building Carbon Emission Calculation Standard", calculate the quantitative measurement results of the embodied carbon of the target building materials during the reconstruction stage.

[0098] Among them, C cg is the quantitative measurement result of the embodied carbon of the target building materials during the reconstruction stage, M i is the actual recycling amount of the i-th type of recyclable building material, F i is the carbon emission factor of the i-th recyclable building material.

[0099] The target building materials include several building materials, and the value of i is how many. For each building material, it is necessary to find the carbon emission factor in the standard, that is, kgCO 2 / unit building material quantity, and determine the actual recycling amount of the building material, then multiply the two, and then add up the multiplied results of various building materials to obtain the embodied carbon quantitative measurement results of the target building material during the reconstruction stage.

[0100] Of course, other methods can also be used to obtain the quantitative measurement results of the embodied carbon of the target building materials during the reconstruction stage, for example: searching the historical records for the quantitative measurement results of the embodied carbon similar to the reconstruction of the target building materials this time, and adjusting them according to the differences between the two building materials, thereby obtaining the quantitative measurement results of the embodied carbon of the target building materials during the reconstruction stage this time. The specific method for obtaining the quantitative measurement results of the embodied carbon of the target building materials during the reconstruction stage is not limited here.

[0101] From the above content, it can be seen that by looking up the carbon emission factor of the target building materials through the "Building Carbon Emission Calculation Standard" and multiplying it with the actual recycling amount of the target building materials, the embodied carbon quantitative measurement results of the target building materials in the reconstruction stage can be accurately obtained, thereby improving the accuracy of the embodied carbon quantitative measurement results of the target building throughout its life cycle.

[0102] Furthermore, as an extension of the above step S103, after obtaining the quantitative measurement results of the embodied carbon of the target building throughout its life cycle, the embodied carbon of the target building can also be graded based on the results, so that the subsequent material selection of the building can have sufficient data support.

[0103] Specifically, after the above step S103, the method may include:

[0104] Step F1: Obtain the quantitative measurement results of the embodied carbon of the benchmark building physical model over the entire life cycle.

[0105] Among them, the quantitative calculation results of embodied carbon are obtained based on the "General Specification for Energy Conservation and Renewable Energy Utilization in Buildings", "Energy Conservation Design Standard for Residential Buildings in Severely Cold and Cold Areas", "Energy Conservation Design Standard for Residential Buildings in Hot Summer and Cold Winter Areas" and "Energy Conservation Design Standard for Residential Buildings in Hot Summer and Warm Winter Areas".

[0106] The benchmark building physical model here is essentially a building model that meets the characteristics of most buildings. In theory, carbon emissions can also be calculated over the entire life cycle of the model, that is, through the "General Specification for Building Energy Conservation and Renewable Energy Utilization" GB 55015-2021, "Energy Conservation Design Standard for Residential Buildings in Severe Cold and Cold Regions" JGJ26-2018, "Energy Conservation Design Standard for Residential Buildings in Hot Summer and Cold Winter Regions" JGJ134-2010, "Energy Conservation Design Standard for Residential Buildings in Hot Summer and Warm Winter Regions" JGJ75-2012, the embodied carbon quantitative calculation results of the benchmark building physical model over the entire life cycle are estimated. Of course, if the standards are updated, the embodied carbon will be estimated based on the latest updated standards.

[0107] Step F2: According to C js =C jz -C sj , calculate the embodied carbon reduction over the life cycle of the target building.

[0108] Among them, C js is the reduction of embodied carbon in the entire life cycle of the target building, C jz is the quantitative calculation result of the embodied carbon in the whole life cycle of the benchmark building physical model, C sj Quantify the embodied carbon measurements for the entire life cycle of the target building.

[0109] The baseline building physical model estimates the embodied carbon of the theoretical building, while the target building’s actual embodied carbon is calculated. By subtracting the two, we can know the increase or decrease in embodied carbon of the target building compared to the model. Both the total embodied carbon and the reduction in embodied carbon are expressed in tCO 2 e indicates.

[0110] Step F3: Determine the level of embodied carbon in the target building’s entire life cycle based on the embodied carbon reduction in the target building’s entire life cycle.

[0111] Among them, the grade is used to optimize the material selection of buildings that are the same as the target building.

[0112] The greater the reduction in embodied carbon of a target building, the higher the embodied carbon level of the target building. The highest embodied carbon level is level 1.

[0113] After determining the level of embodied carbon of the target building, building materials with lower carbon emissions can be selected for future similar buildings based on the level to reduce the embodied carbon of the building.

[0114] From the above content, it can be seen that the reduction of the embodied carbon of the target building is calculated through the benchmark building physical model, and then the carbon emission level of the target building is determined based on the reduction. In the selection of materials for subsequent buildings, it is possible to refer to the carbon emission levels of similar buildings in the past to select lower-carbon building materials, thereby reducing the overall carbon emissions of the building and protecting the environment more effectively.

[0115] Furthermore, before the above step F3, the method may further include:

[0116] Step F301: According to , calculate the embodied carbon reduction rate of the target building over its entire life cycle.

[0117] Among them, μ c is the embodied carbon reduction rate of the target building over its entire life cycle, C js is the reduction of embodied carbon in the entire life cycle of the target building, C jz The embodied carbon quantitative measurement results of the entire life cycle of the benchmark building physical model.

[0118] The embodied carbon reduction rate of the target building, that is, the ratio of the embodied carbon reduction of the target building to the embodied carbon of the benchmark building physical model.

[0119] Step F302: According to , calculate the embodied carbon emission intensity of the target building over its entire life cycle.

[0120] Among them, C lc is the embodied carbon emission intensity of the target building throughout its life cycle, C sj is the quantitative measurement result of the embodied carbon in the whole life cycle of the target building, A is the total building area of ​​the target building, μ e The building energy efficiency rate of the target building;

[0121] The embodied carbon of the target building and the total area of ​​the target building (in m 2 ) divided by the target building area is the embodied carbon per unit area (in tCO2 e / m 2 ). Subtracting the energy saving rate of the target building from 1 gives the energy utilization rate of the target building. Multiplying the two gives the actual embodied carbon emission level of the target building, i.e., the embodied carbon emission intensity.

[0122] Accordingly, the above step F3 may include:

[0123] Step F303: According to the embodied carbon reduction rate of the target building over its entire life cycle and the embodied carbon emission intensity of the target building over its entire life cycle, the embodied carbon grade of the target building over its entire life cycle is determined in the embodied carbon grade table.

[0124] Among them, the embodied carbon classification table includes multiple levels. The lower the level, the greater the embodied carbon reduction rate and the lower the embodied carbon emission intensity.

[0125] For example, the embodied carbon assessment of a building's entire life cycle is divided into five levels, namely, level 1, level 2, level 3, level 4, and level 5. Level 1 is a low embodied carbon building, level 3 is a medium embodied carbon building, level 5 is a high embodied carbon building, level 2 is between medium and low embodied carbon buildings, and level 4 is between medium and high embodied carbon buildings. The following table 1 is a grading table for embodied carbon in buildings.

[0126] Table 1 Classification of embodied carbon in buildings

[0127]

[0128] Assume that the embodied carbon reduction rate of building A is 16.00% and the embodied carbon emission intensity is 0.30 tCO 2 e / m 2 , then the carbon emission level of building A is level 2. The embodied carbon reduction rate of building B is 30.00% over its entire life cycle, and the embodied carbon emission intensity is 0.50 tCO 2 e / m 2 , then the carbon emission level of building B is level 3. The building’s carbon reduction rate and carbon emission intensity must meet the standards of the corresponding level to be determined as this level.

[0129] From the above content, it can be seen that the carbon reduction rate and carbon emission intensity can more accurately characterize the implicit carbon emissions of the target building, and then the carbon emission level of the target building can be more accurately determined, so that more environmentally friendly material selection can be made in the subsequent material selection of the same or similar buildings based on the carbon emission level of the target building.
