[0021] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0022] The term "exemplary" used herein means "serving as an example, embodiment, or illustration". Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments.

[0023] As used herein, the term "and / or" is merely a description of the relationship between associated objects, indicating that there can be three relationships. For example, A and / or B can represent three cases: A exists alone, both A and B exist simultaneously, and B exists alone. Additionally, the term "at least one" as used herein means any one or any combination of at least two of multiple items. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set composed of A, B, and C.

[0024] In addition, for a better illustration of the present disclosure, numerous specific details are given in the following specific implementation manners. Those skilled in the art should understand that the present disclosure can still be implemented without certain specific details. In some instances, methods, means, elements, and circuits well-known to those skilled in the art are not described in detail to highlight the gist of the present disclosure.

[0025] Building carbon emissions can represent the amount of carbon dioxide emissions generated by a building during its related construction and demolition phases and operation phase. Building carbon emissions generally include embodied carbon emissions and operational carbon emissions; among them, the embodied carbon emissions can represent the carbon emissions generated due to activities such as the production and transportation of building materials, and the construction and demolition of the building, mainly from the production of building materials; the operational carbon emissions can represent the total carbon emissions of the building during its entire usage period (i.e., from after construction until demolition). For general buildings, the embodied carbon emissions account for approximately 25% of the building's life-cycle carbon emissions, and the operational carbon emissions account for approximately 75% of the building's life-cycle carbon emissions; while for high-energy-efficiency buildings, the proportion of embodied carbon emissions may exceed 50%.

[0026] Accurately assessing the life-cycle carbon emissions corresponding to a building is very important for formulating building low-carbon transformation strategies. The commonly used methods for determining building carbon emissions in the prior art mainly target buildings based on conventional building materials and engineering components such as concrete and steel bars. However, for plant-based buildings, since the plant-based building materials used can themselves serve as carbon carriers, the life cycle of plant-based buildings is not exactly the same as that of buildings constructed with conventional building materials. Therefore, through the commonly used methods for determining building carbon emissions in the prior art, it is impossible to accurately summarize the life cycle of plant-based buildings, and thus impossible to accurately calculate the life-cycle carbon emissions corresponding to plant-based buildings.

[0027] In view of this, the present disclosure provides a method for determining the carbon emissions of a plant-based building throughout its life cycle. It can divide the life cycle stages of the target plant-based building according to the characteristics of the plant-based materials used in the target plant-based building as carbon carriers, and determine the corresponding carbon emissions for each life cycle stage corresponding to the target plant-based building, which can improve the accuracy of the embodied carbon emissions corresponding to the target plant-based building, and further improve the accuracy of the carbon emissions throughout the life cycle corresponding to the target plant-based building. The following details the method for determining the carbon emissions of a plant-based building throughout its life cycle provided by the present disclosure.

[0028] Figure 1 FIG. shows a flowchart of a method for determining the carbon emissions of a plant-based building throughout its life cycle according to an embodiment of the present disclosure. The method for determining the carbon emissions of a plant-based building throughout its life cycle can be executed by an electronic device such as a terminal device or a server. The terminal device can be a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. The method for determining the carbon emissions of a plant-based building throughout its life cycle can be implemented by a processor calling computer-readable instructions stored in a memory. Alternatively, the method for determining the carbon emissions of a plant-based building throughout its life cycle can be executed by a server. As Figure 1 shown, the method for determining the carbon emissions of a plant-based building throughout its life cycle includes:

[0029] In step S11, according to the life cycle stage corresponding to the target plant-based building, determine the embodied carbon emissions corresponding to the target plant-based building, where the target plant-based building is constructed by at least one plant-based material, and the life cycle stage includes a carbon absorption stage, a carbon storage stage, a carbon transfer stage, and a carbon release stage.

[0030] The target plant-based building here can represent a building constructed by at least one plant-based material. Its specific form can refer to the implementation in related technologies. For example, a bamboo house, a wooden house, etc. The present disclosure does not make specific limitations on this. Among them, the plant-based material can represent a building material made from plants. Its specific form can refer to the implementation in related technologies. For example, wooden materials or bamboo materials, etc. The present disclosure does not make specific limitations on this.

[0031] For any plant-based material, during the growth process of the corresponding plant, it can absorb carbon dioxide in the environment through photosynthesis. After the mature plant is harvested and processed into a plant-based material, it can act as a carbon carrier to achieve carbon sequestration and reduce carbon emissions in the form of carbon-based storage.

[0032] In the prior art, the building life cycle is usually divided based on time clues. For example, the building life cycle stipulated in the international standard ISO21930 includes stages such as building material production, building construction, use, scrapping, and recycling and reuse; the "Building Carbon Emission Calculation Standard" GB / T 51366-2019 in China stipulates that the building life cycle includes stages such as building material production and transportation, building construction, building operation, and building demolition. These methods of dividing the building life cycle cannot reflect the carbon emission impact generated by the plants corresponding to the plant-based materials during the growth process. Moreover, dividing the building life cycle stages in the above manner will increase the complexity of the process of determining the embodied carbon emissions and the life cycle carbon emissions, which is not conducive to estimating the life cycle carbon emissions in the early stage of building design, as well as the comparison and optimization of building construction plans.

[0033] Therefore, in view of the characteristics of plant-based buildings as carbon carriers, the life cycle corresponding to the target plant-based building is divided into a carbon absorption stage, a carbon storage stage, a carbon transfer stage, and a carbon release stage. Among them, the carbon absorption stage may include the process in which the plants corresponding to each plant-based material in the target plant-based building grow and absorb carbon dioxide; the carbon storage stage may include the time from the completion of the manufacture of each plant-based material until degradation and / or recycling; the carbon transfer stage may include the manufacturing process, transportation, and construction of the target plant-based building, etc., during which various material and energy transfers occur; the carbon release stage may include the process of recycling and reusing each plant-based material separately and releasing carbon dioxide after the target plant-based building is demolished.

[0034] According to the above division of the life cycle stages, the process of determining the embodied carbon emissions corresponding to the target plant-based building can be simplified, enabling the rapid determination of the embodied carbon emissions corresponding to the target plant-based building based on the usage amount of each plant-based material, and improving the accuracy of the embodied carbon emissions.

[0035] The process of determining the embodied carbon emissions corresponding to the target plant-based building according to the life cycle stages corresponding to the target plant-based building will be described in detail later in combination with possible implementation manners of the present disclosure, and will not be elaborated here.

[0036] In step S12, determine the operating carbon emissions corresponding to the target plant-based building.

[0037] Similar to the building constructed with conventional building materials, the target plant-based building will also consume energy and generate corresponding carbon emissions during operation. By analyzing the operation process of the target plant-based building, the operating carbon emissions corresponding to the target plant-based building can be determined. The specific method can refer to the implementation manners in related technologies, and the present disclosure does not make specific limitations thereon.

[0038] The process of determining the operational carbon emissions corresponding to the target plant-based building will be described in detail in combination with possible implementation manners of the present disclosure later, and will not be elaborated here.

[0039] In step S13, according to the embodied carbon emissions and the operational carbon emissions, determine the life cycle carbon emissions corresponding to the target plant-based building.

[0040] Based on the embodied carbon emissions of the target plant-based building over its life cycle and the operational carbon emissions of the target plant-based building during operation, the life cycle carbon emissions corresponding to the target plant-based building can be determined.

[0041] In an embodiment of the present disclosure, the embodied carbon emissions corresponding to the target plant-based building can be determined according to the life cycle stage corresponding to the target plant-based building, where the target plant-based building is constructed by at least one plant-based material, and the life cycle stage includes a carbon absorption stage, a carbon storage stage, a carbon transfer stage, and a carbon release stage; determine the operational carbon emissions corresponding to the target plant-based building; according to the embodied carbon emissions and the operational carbon emissions, the life cycle carbon emissions corresponding to the target plant-based building can be determined. By dividing the life cycle stage of the target plant-based building according to the characteristics of the plant-based materials used in the target plant-based building itself as carbon carriers, and determining the corresponding carbon emissions for each life cycle stage corresponding to the target plant-based building, the process of determining the embodied carbon emissions corresponding to the target plant-based building can be simplified, the complexity of determining the embodied carbon emissions can be reduced, and the accuracy of the embodied carbon emissions can be improved, thereby improving the accuracy of the life cycle carbon emissions corresponding to the target plant-based building.

[0042] In a possible implementation manner, determining the embodied carbon emissions corresponding to the target plant-based building according to the life cycle stage corresponding to the target plant-based building includes: determining the carbon absorption parameter corresponding to each plant-based material in the carbon absorption stage of the target plant-based building, where the carbon absorption parameter corresponding to any one plant-based material includes the carbon absorption amount of the plant corresponding to the plant-based material within a preset time; determining the total carbon storage amount corresponding to the carbon storage stage according to the carbon absorption parameter corresponding to each plant-based material; determining the first carbon emissions corresponding to the carbon transfer stage according to the processing method and transportation method corresponding to each plant-based material; determining the second carbon emissions corresponding to the carbon release stage based on the residual material production efficiency corresponding to each plant-based material, where the residual material production efficiency corresponding to any one plant-based material is used to represent the efficiency of generating biomass energy when the plant-based material is reused for energy; determining the embodied carbon emissions according to the total carbon storage amount, the first carbon emissions, and the second carbon emissions.

[0043] For any plant-based material, the carbon absorption amount of the plant corresponding to the plant-based material within a preset time can be represented by the carbon absorption parameter corresponding to the plant-based material, so as to quantitatively reflect the carbon absorption capacity of the plant-based material. The specific form of the carbon absorption parameter can be flexibly set according to actual usage requirements. For example, the carbon absorption parameter can be expressed as the carbon absorption amount of the plant per unit area within a preset time, or the carbon absorption amount of a single plant within a preset time, etc. The present disclosure does not make specific limitations on this; the specific value of the preset time here can be flexibly set according to actual usage requirements. For example, the preset time can be set to one year, etc. The present disclosure does not make specific limitations on this.

[0044] For any plant-based material, the specific manner of determining the carbon absorption parameter corresponding to the plant-based material can refer to the implementation manners in related technologies. The present disclosure does not make specific limitations on this.

[0045] In one example, for any plant-based material, the carbon absorption parameter corresponding to the plant-based material can be determined according to the total ecosystem carbon (TEC) of the plant corresponding to the plant-based material.

[0046] The TEC corresponding to any plant can reflect the amount of carbon dioxide inhaled by the ecosystem of the plant in one year. Its specific value depends on the biomass accumulated by the plant through annual photosynthesis and is affected by factors such as the type of the plant, growth conditions, and management measures corresponding to the plant. Due to the limited lifespan of plants, the ecosystem of any plant will reach a total TEC balance (saturation) state after meeting the preset time limit. At this time, the carbon absorption of new plants and the carbon release of aging and withering plants achieve a dynamic balance. On this basis, the carbon absorption parameter corresponding to the plant, that is, the material, can be determined according to the total TEC of the ecosystem of the plant.

[0047] Furthermore, because TEC is usually distributed in living biomass, withered plants and soil, for example, according to the Food and Agriculture Organization of the United Nations (FAO), 53% of the TEC corresponding to the global forest is distributed in the living biomass of the forest, 8% is distributed in the dead wood of the forest, and 39% is distributed in the soil of the forest. In the prior art, the raw materials for manufacturing plant-based materials are usually obtained by cutting down plants of appropriate age, which does not affect the carbon base distributed in withered plants and soil. Therefore, to determine the carbon absorption parameters corresponding to any plant-based material, it is only necessary to consider the living biomass part of the plant ecosystem corresponding to the plant-based material. For any plant-based material, according to the living biomass part of the TEC of the plant corresponding to the plant-based material, the specific method of determining the carbon absorption parameters corresponding to the plant-based material can refer to the implementation methods in the relevant technology, for example, it can be determined according to the ecological statistical data corresponding to the plant and the preset time, etc., and the present disclosure does not make specific limitations on this.

[0048] In one example, the plant-based material is bamboo material. Using forestry engineering statistical data, the carbon dioxide absorption of each hectare of bamboo forest in one year can be determined. a (CO 2 / ha·yr), and C a Determine the carbon absorption parameters corresponding to bamboo materials.

[0049] Any plant-based material is usually a durable material made from the corresponding plant. Before the plant-based material is biodegraded or recycled, the carbon absorbed by the plant-based material in the carbon absorption stage is released back to the atmosphere in the form of carbon dioxide. The plant-based material can be used as a carbon carrier to achieve carbon storage. Therefore, according to the carbon absorption parameters corresponding to each plant-based material, the total amount of carbon storage corresponding to the target plant-based building in the carbon storage stage can be determined.

[0050] During the processing and production of plant-based materials and the transportation of plant-based materials to the construction site of the target plant-based building, material and energy transfer will occur, and corresponding carbon emissions will be generated. The carbon emissions generated by these processes can be determined as the carbon emissions generated by the target plant-based building in the carbon transfer stage. Therefore, the first carbon emissions corresponding to the carbon transfer stage can be determined based on the processing and transportation methods corresponding to each plant-based material.

[0051] After the operation time of the target plant-based building meets the preset service life, the target plant-based building is usually demolished and recycled. Among them, some plant-based materials that can be used for secondary construction of plant-based buildings do not produce carbon emissions, while some plant-based materials that cannot be used for secondary construction of plant-based buildings need to be treated at the end.

[0052] In the prior art, the methods for treating plant-based materials at the end mainly include biomass pellet technology (BP) and biochar technology (BC). Among them, biomass pellet technology can represent a technology that uses bio-based materials to produce biomass energy to replace fossil energy and achieve carbon emission reduction; therefore, treating plant-based materials by biomass pellet technology will produce carbon emissions during the process of generating biomass energy. Biochar technology can represent a technology that uses material technology to extend the carbon sequestration time of bio-based materials or generate highly stable carbon compounds to reduce carbon emissions; therefore, treating plant-based materials by biochar technology will not produce new carbon emissions.

[0053] In view of this, during the carbon emission stage corresponding to the target plant-based building, only the carbon emissions of the part of plant-based materials treated by biomass pellet technology need to be considered. Specifically, the residual material production efficiency corresponding to each plant-based material can be determined respectively to represent the efficiency of generating biomass energy when the plant-based material is reused for energy; and then, based on the residual material production efficiency corresponding to each plant-based material, the second carbon emission amount corresponding to the carbon release stage can be determined.

[0054] The total carbon storage, the first carbon emission amount, and the second carbon emission amount corresponding to the target plant-based building can reflect all the carbon emission impacts on the atmosphere during the period from plant growth to the demolition and recycling of the target plant-based building, excluding operation. Therefore, the embodied carbon emissions can be determined according to the total carbon storage, the first carbon emission amount, and the second carbon emission amount.

[0055] In a possible implementation manner, determining the total carbon storage corresponding to the carbon storage stage according to the carbon absorption parameter corresponding to each plant-based material includes: for any plant-based material, determining the raw material carbon storage amount corresponding to the plant-based material according to the carbon absorption parameter corresponding to the plant-based material; for any plant-based material, respectively determining the building material carbon storage amount and the residual material carbon storage amount corresponding to the plant-based material according to the raw material carbon storage amount corresponding to the plant-based material; and determining the total carbon storage according to the building material carbon storage amount and the residual material carbon storage amount corresponding to each plant-based material.

[0056] Specifically, for any plant-based material, the raw material carbon storage corresponding to the plant-based material is determined according to the carbon absorption parameter corresponding to the plant-based material, the growth time of the plant corresponding to the plant-based material, and the biomass of the plant consumed during the processing of the plant-based material.

[0057] Taking the above plant-based material as a bamboo material, and the carbon absorption parameter corresponding to the bamboo material is C a as an example, the raw material carbon storage corresponding to the bamboo material can be expressed by formulas (1) to (3):

[0058]

[0059] Among them, C s,rm represents the raw material carbon storage corresponding to the bamboo material, with the unit of kgCO 2 ; Y represents the growth years of the harvested bamboo plants, with the unit of year (yr); M d represents the above-ground biomass of the bamboo plants required to produce 1 function unit (FU) of the bamboo material, with the unit of kilogram (kg). Among them, the specific content of FU depends on the specific form of the bamboo material. For example, when the bamboo material is a square timber, 1FU can be set to 1m 3 , when the bamboo material is a board, 1FU can be set to 1m 2 , when the bamboo material is a loose material, 1FU can be set to 1kg, etc. The present disclosure does not make specific limitations on this; M 0 represents the above-ground biomass of the bamboo plants per hectare of the bamboo forest, with the unit of kilogram per hectare (kg / ha); M FU represents the mass of 1FU of the bamboo material, with the unit of kg; λ represents the material utilization rate of producing the bamboo material, with the unit of percentage (%); u represents the moisture content of the bamboo plants, with the unit of %; λ i represents the utilization rate of the raw materials in the i-th process of producing the bamboo material, with the unit of %; M di represents the dry mass of the intermediate product before the i-th process of producing the bamboo material, with the unit of kg; m di represents the dry mass of the intermediate product obtained after the i-th process of producing the bamboo material, with the unit of kg.

[0060] For any kind of plant-based material, during the process of processing the plant-based material into building materials required for constructing a target plant-based building, there will be losses of the plant-based material, that is, processing leftovers are generated. For example, during the process of processing wooden boards into door and window frames, leftovers such as wood chips are generated. A part of these processing leftovers is used for end treatment to produce biomass energy, and the other part is still used for carbon storage. Therefore, for any kind of plant-based material, the building material carbon storage and leftover carbon storage corresponding to the plant-based material can be determined respectively according to the raw material carbon storage corresponding to the plant-based material.

[0061] Taking the above plant-based material as bamboo material, the carbon absorption parameter corresponding to the bamboo material is C a as an example. The building material carbon storage corresponding to any kind of plant-based material can be expressed by formula (4):

[0062]

[0063] Among them, C s,bm represents the building material carbon storage corresponding to the bamboo material, with the unit of kilogram of carbon dioxide (kgCO 2 ).

[0064] The leftover carbon storage corresponding to any kind of plant-based material can be expressed by formula (5):

[0065]

[0066] Among them, C s,lo represents the leftover carbon storage corresponding to the bamboo material, with the unit of kgCO 2 ; ε represents the proportion of leftovers used for end treatment to produce biomass energy, with the unit of %.

[0067] According to the building material carbon storage and leftover carbon storage corresponding to each plant-based material, the total carbon storage can be determined.

[0068] Taking the above plant-based material as bamboo material, the carbon absorption parameter corresponding to the bamboo material is C a as an example. The total carbon storage corresponding to the target plant-based building can be expressed by formula (6):

[0069]

[0070] Among them, C s represents the total carbon storage corresponding to the target plant-based building, with the unit of kgCO 2 .

[0071] In a possible implementation, according to the processing method and transportation method corresponding to each plant-based material, the first carbon emission amount corresponding to the carbon transfer stage is determined, including: for any plant-based material, according to the processing method corresponding to the plant-based material, the processing carbon emission amount corresponding to the plant-based material is determined; for any plant-based material, according to the consumption amount of additional materials used in the processing process of the plant-based material, the additional material carbon emission amount corresponding to the plant-based material is determined; for any plant-based material, according to the transportation method corresponding to the plant-based material, the transportation carbon emission amount corresponding to the plant-based material is determined; according to the processing carbon emission amount, additional material carbon emission amount and transportation carbon emission amount corresponding to each plant-based material, the first carbon emission amount is determined.

[0072] For any plant-based material, at least one kind of energy needs to be consumed during its processing, and corresponding carbon emissions are generated. Therefore, according to the processing method corresponding to the plant-based material, the processing carbon emission amount corresponding to the plant-based material can be determined.

[0073] In an example, the plant-based material is a bamboo material, and its processing method requires m different processing procedures, and each processing procedure requires n different types of energy (such as fossil energy, electric energy, etc.). The processing carbon emission amount corresponding to the bamboo material can be expressed by formula (7):

[0074]

[0075] Among them, C t,e represents the processing carbon emission amount corresponding to the bamboo material, with the unit of kgCO 2 ; P i,j represents the consumption amount of the i-th type of energy in the j-th processing procedure, and its unit can be flexibly set according to the actual usage requirements, depending on the actual situation of the energy used. For example, when the energy used is coal, its corresponding unit is kg; when the energy used is gasoline, its corresponding unit is liters (L); when the energy used is electric energy, its corresponding unit is kilowatt-hours (kWh), etc. The present disclosure does not make specific limitations; CF ei represents the carbon emission factor corresponding to the i-th type of energy, which is used to reflect the carbon dioxide emission amount generated per unit consumption of the energy, and its unit can be flexibly set according to the actual usage requirements, depending on the actual situation of the energy used. For example, when the energy used is fossil energy, the unit of its corresponding carbon emission factor can be kilograms of carbon dioxide per ton of standard coal (kgCO 2 / tce), when the energy used is electric energy, the unit of its corresponding carbon emission factor can be kilograms of carbon dioxide per kilowatt-hour (kgCO 2 / kWh), etc. The present disclosure does not make specific limitations on this.

[0076] For any kind of plant-based material, during its processing, it may be necessary to consume a variety of additional materials. The material transfer brought about by these additional materials will also increase carbon emissions. Therefore, the carbon emissions of the additional materials corresponding to the plant-based material can be determined according to the consumption of the additional materials used in the processing of the plant-based material. Among them, the specific form of the additional materials can be flexibly set according to actual usage requirements. For example, it can include adhesives, preservatives, etc. The present disclosure does not make specific limitations on this.

[0077] Taking the above plant-based material as a bamboo material as an example, a total of n different additional materials are required in its processing. The carbon emissions of the additional materials corresponding to the bamboo material can be expressed by formula (8):

[0078]

[0079] Among them, C t,m represents the carbon emissions of the additional materials corresponding to the bamboo material, with the unit of kgCO 2 ; M i represents the consumption of the i-th additional material, with the unit of kg; CF mi represents the carbon emission factor corresponding to the i-th additional material, with the unit of kilograms of carbon dioxide per kilogram (kgCO 2 / kg).

[0080] For the transportation process of plant-based materials, different transportation methods will generate different levels of carbon emissions, and these carbon emissions also belong to the first carbon emissions generated by the target plant-based building during the carbon transfer stage. Therefore, for any kind of plant-based material, the transportation carbon emissions corresponding to the plant-based material can be determined according to the transportation method corresponding to the plant-based material.

[0081] Taking the above plant-based material as a bamboo material as an example, the bamboo materials used to construct the target plant-based building include n different forms. For example, it can include square timbers, boards, and loose materials, etc. These bamboo materials are transported by m different transportation methods. The transportation carbon emissions corresponding to the bamboo material can be expressed by formula (9):

[0082]

[0083] Among them, C t,tran The transportation carbon emissions corresponding to the bamboo material, with the unit of kgCO 2 ; M i,j represents the mass of the j-th bamboo material transported by the i-th transportation method, with the unit of kg; D i,j represents the transportation distance when the j-th bamboo material is transported by the i-th transportation method, with the unit of kilometers / kilometers (km); CF tran,iIndicates the carbon emission factor corresponding to the i-th transportation mode, with the unit of kilograms of carbon dioxide per ton per kilometer (kgCO 2 / t·km).

[0084] According to the processing carbon emissions, additional material carbon emissions, and transportation carbon emissions corresponding to each plant-based material, the first carbon emissions can be determined.

[0085] Taking the above plant-based material as bamboo material as an example, the first carbon emissions corresponding to the target plant-based building can be expressed as formula (10):

[0086]

[0087] Among them, C t Indicates the first carbon emissions corresponding to the standard plant-based building, with the unit of kgCO 2 .

[0088] In a possible implementation manner, based on the residual material production efficiency corresponding to each plant-based material, the second carbon emissions corresponding to the carbon release stage are determined, including: for any plant-based material, according to the residual material production efficiency corresponding to the plant-based material, the residual material production carbon emissions corresponding to the plant-based material are determined; according to the residual material production carbon emissions corresponding to each plant-based material, the second carbon emissions are determined.

[0089] For any plant-based material, according to the residual material production efficiency corresponding to the plant-based material and the dry weight of the residual material corresponding to the plant-based material, the residual material production carbon emissions corresponding to the plant-based material can be determined. Among them, the specific method for determining the residual material production efficiency corresponding to any plant-based material can refer to the implementation manner in the related technology. For example, it can be determined by the sample data collected through literature research, etc. The present disclosure does not make specific limitations in this regard; the specific content of the residual material corresponding to any plant-based material can be flexibly set according to actual usage requirements. For example, it can include the processing residual materials generated during the processing of the plant-based building and the recycled residual materials recovered after demolition, etc. The present disclosure does not make specific limitations in this regard; the specific method for determining the mass of the residual material corresponding to each plant-based material can be flexibly set according to actual usage requirements. The present disclosure does not make specific limitations in this regard.

[0090] Taking the above plant-based material as bamboo material as an example, after the target plant-based building is demolished, no recycled residual materials are generated, and the residual materials corresponding to the bamboo material only include processing residual materials. Then the dry weight of the residual materials corresponding to the bamboo material can be expressed as formula (11):

[0091]

[0092] Among them, M lo,d Indicates the dry weight of the residual materials corresponding to the bamboo material, with the unit of kg.

[0093] Based on this, the residual material production capacity emissions corresponding to the bamboo material can be expressed by formula (12):

[0094]

[0095] Among them, C r,bam represents the residual material production capacity emissions corresponding to the bamboo material, with the unit of kgCO 2 ; P lo represents the residual material production capacity efficiency corresponding to the bamboo material, with the unit of %; K represents the carbon content rate of the residual material, with the unit of %; 44 / 12 represents the ratio of the molecular weights of carbon dioxide and carbon atoms.

[0096] According to the residual material production capacity carbon emissions corresponding to each plant-based material used in the construction of the target plant-based building, the second carbon emissions corresponding to the target plant-based building can be determined.

[0097] In an example, when constructing the target plant-based building using m different plant-based materials, the second carbon emissions corresponding to the target plant-based building can be expressed by formula (13):

[0098]

[0099] Among them, C r represents the second carbon emissions corresponding to the target plant-based building, with the unit of kgCO 2 ; C r,i represents the residual material production capacity carbon emissions corresponding to the i-th plant-based material, with the unit of kgCO 2 .

[0100] Through the above process, the embodied carbon emissions corresponding to the target plant-based building can be determined based on the total carbon storage, the first carbon emissions, and the second carbon emissions corresponding to the target plant-based building. The embodied carbon emissions can be expressed by formula (14):

[0101]

[0102] Among them, C bm represents the embodied carbon emissions corresponding to the target plant-based building, with the unit of kgCO 2 .

[0103] In a possible implementation manner, determining the operational carbon emissions corresponding to the target plant-based building includes: determining the building operational energy consumption during the operation of the target plant-based building based on the coupled heat and moisture process model; and determining the operational carbon emissions according to the building operational energy consumption.

[0104] Since plant-based buildings usually have the characteristic of hygroscopicity, there are significant differences in their energy consumption during operation compared to buildings constructed with conventional building materials. Therefore, in order to improve the accuracy of the operating carbon emissions of the target plant-based building, it is necessary to analyze the building operation energy consumption of the target plant-based building during operation according to its operating characteristics.

[0105] The heat and moisture processes in a building can include a heat transfer process and a moisture transfer process. Among them, the heat transfer process is usually realized with temperature as the driving potential; the moisture transfer process is related to factors such as temperature, moisture content, vapor pressure, suction stress, and relative humidity. By adaptively setting the driving potentials corresponding to the heat transfer process and the moisture transfer process, a corresponding coupled heat and moisture process model can be constructed to describe the heat and moisture processes in the building.

[0106] On this basis, using the coupled heat and moisture process model, the operation process of the target plant-based building can be simulated and analyzed to determine the building operation energy consumption corresponding to the target plant-based building. Among them, the specific form of the coupled heat and moisture process model can refer to the implementation methods in related technologies. For example, the high-temperature coupled heat and moisture process model, the Künzel coupled heat and moisture process model, etc. The present disclosure does not make specific limitations on this.

[0107] Figure 2 A schematic diagram showing the heat and moisture process corresponding to a plant-based building according to an embodiment of the present disclosure is as follows Figure 2 As shown, the black arrows represent the unsteady heat transfer process; the light gray arrows represent the unsteady moisture transfer process. The heat transfer process includes the heat transfer caused by the temperature difference between the indoor and outdoor temperatures, as well as the latent heat absorption process when moisture is converted from liquid water to gaseous water and the latent heat release process when moisture is converted from gaseous water to liquid water. Since temperature and moisture content are not the direct driving potentials for moisture transfer, and it is difficult to determine the transfer coefficient obtained by combining these two factors, which will increase the difficulty and complexity of quantitatively describing the moisture transfer process by means of functions, etc.; and capillary suction stress cannot be applied to dry and non-capillary active materials and cannot be directly measured in wet materials. Therefore, in the embodiments of the present disclosure, vapor pressure and relative humidity are selected as the driving potentials for the moisture transfer process to describe the process of moisture conversion between liquid water and gaseous water and the moisture transfer between indoor and outdoor.

[0108] On this basis, the Künzel coupled heat and moisture process model including the coupled differential equation corresponding to the heat transfer process and the coupled differential equation corresponding to the moisture transfer process can be determined. Among them, the coupled differential equation corresponding to the heat transfer process can be expressed as formula (15):

[0109]

[0110] Among them, Represents the heat storage process of the plant-based building enclosure structure; Represents the heat transfer process caused by the temperature difference between indoors and outdoors; Represents the latent heat change process when moisture converts between liquid water and gaseous water; H represents the enthalpy of the moist plant-based material per unit volume, in joules per cubic meter (J / m 3 ); Represents the Celsius temperature (°C); λ represents the thermal conductivity of the moist plant-based material, in watts per meter per kelvin (W / (m·K)); h v Represents the enthalpy of water evaporation, in joules per kilogram (J / kg); δ represents the permeability coefficient corresponding to water vapor, in kilograms per meter per second per pascal (kg / (m·s·Pa)); p represents the water vapor partial pressure, in pascals (Pa); μ represents the water vapor permeance resistance factor of the dry plant-based material.

[0111] The coupled differential equation corresponding to the moisture transfer process can be expressed as Equation (16):

[0112]

[0113] Wherein, Represents the wet storage process of the plant-based material; Represents the transfer process of liquid water; Represents the transfer process of gaseous water (water vapor); ρ l Represents the liquid water density, in kilograms per cubic meter (kg / m 3 ); φ represents the relative humidity; D 1 Represents the liquid water transfer coefficient, in square meters per second (m 2 / s); u represents the mass ratio moisture content, in kilograms per kilogram (kg / kg).

[0114] Based on the Kunzel heat and moisture transfer coupling model, the heat and moisture transfer process of the building enclosure structure corresponding to the target plant-based building can be simulated, the operating state of the target plant-based building can be analyzed, and the building operation energy consumption during the operation process of the target plant-based building can be determined. Among them, for the specific process of simulating the heat and moisture transfer process of the building enclosure structure corresponding to the target plant-based building and analyzing the operating state of the target plant-based building, reference can be made to the implementation manners in related technologies, and the present disclosure does not make specific limitations thereto.

[0115] In one example, a non-steady transient heat and moisture transfer analysis program (Wärme-Und Feuchtetransport Instationär, WUFI) based on the Kunzel heat and moisture process coupling model can be used to simulate the heat and moisture processes of the building envelope structure corresponding to the target plant-based building, and analyze the operating state of the target plant-based building. WUFI can perform dynamic simulations based on the input data, output data such as the instantaneous moisture content of building components and the spatial temperature and humidity fields of the target plant-based building within a preset time, and calculate the building operation energy consumption on the basis of considering the heat and moisture coupling process of the building envelope structure of the target plant-based building to determine the building operation energy consumption corresponding to the target plant-based building. Among them, the specific form and content of the building operation energy consumption corresponding to the target plant-based building can be flexibly set according to actual usage requirements. For example, the building operation energy consumption corresponding to the target plant-based building, and / or the consumption of each type of energy by the target plant-based building per unit time, etc. The present disclosure does not make specific limitations on this.

[0116] According to the building operation energy consumption, the corresponding operating carbon emissions of the target plant-based building can be determined. The specific method can refer to the implementation methods in related technologies, and the present disclosure does not make specific limitations on this.

[0117] In a possible implementation manner, the building operation energy consumption includes: the first consumption corresponding to fossil energy during the operation of the target plant-based building, and the second consumption corresponding to electric energy; determining the operating carbon emissions according to the building operation energy consumption includes: determining the direct carbon emissions corresponding to the target plant-based building according to the first consumption and the carbon emission factor corresponding to fossil energy; determining the indirect carbon emissions corresponding to the target plant-based building according to the second consumption and the carbon emission factor corresponding to electric energy; determining the operating carbon emissions according to the direct carbon emissions and the indirect carbon emissions.

[0118] During the operation of the target plant-based building, the carbon emissions generated by consuming different types of energy are also different. Specifically, when using fossil energy, the carbon emissions generated are direct carbon emissions; when consuming electric energy, the carbon emissions generated are indirect carbon emissions, mainly from the generation process of electric energy. Therefore, according to the type of energy consumed, the building operation energy consumption corresponding to the target plant-based building can be divided into the first consumption corresponding to fossil energy and the second consumption corresponding to electric energy. Among them, the specific form of fossil energy can be flexibly set according to actual usage requirements. For example, it can include gasoline, coal, etc., and the present disclosure does not make specific limitations in this regard; the specific form of the first consumption corresponding to fossil energy can be flexibly set according to actual usage requirements. For example, it can be the consumption of fossil energy per unit time or the total consumption of fossil energy during the total operation time of the target plant-based building, etc., and the present disclosure does not make specific limitations in this regard; the specific form of electric energy, for example, can include electricity, hydrogen fuel, etc., and the present disclosure does not make specific limitations in this regard; the specific form of the second consumption corresponding to electric energy can be flexibly set according to actual usage requirements. For example, it can be the consumption of electric energy per unit time or the total consumption of electric energy during the total operation time of the target plant-based building, etc., and the present disclosure does not make specific limitations in this regard.

[0119] According to the first consumption corresponding to fossil energy and the carbon emission factor corresponding to fossil energy, the direct carbon emissions corresponding to the target plant-based building can be determined. Among them, the specific value of the carbon emission factor corresponding to fossil energy depends on the specific form of fossil energy and can be determined by referring to the implementation methods in the prior art. For example, it can be determined by referring to the "Standard for Calculating Building Carbon Emissions" GB / T 51366-2019 in China, etc., and the present disclosure does not make specific limitations in this regard.

[0120] According to the second consumption corresponding to electric energy and the carbon emission factor corresponding to electric energy, the indirect carbon emissions corresponding to the target plant-based building are determined. Among them, the specific value of the carbon emission factor corresponding to electric energy depends on the specific form of electric energy and can be determined by referring to the implementation methods in the prior art. For example, it can be determined by referring to the annual data released by the Ministry of Ecology and Environment of China, etc., and the present disclosure does not make specific limitations in this regard.

[0121] According to the direct carbon emissions and indirect carbon emissions corresponding to the target plant-based building, the operating carbon emissions corresponding to the target plant-based building are determined.

[0122] In one example, without distinguishing between direct carbon emissions and indirect carbon emissions, the operating carbon emissions corresponding to the target plant-based building can also be expressed by formulas (17) to (18):

[0123]

[0124] Among them, C bo represents the operating carbon emissions corresponding to the target plant-based building, with the unit of kgCO 2 ; n represents the total number of types of energy consumed during the total operating time of the target plant-based building; Ad oper,e,i represents the consumption of the i-th type of energy during the total operating time of the target plant-based building, and its unit can be flexibly set according to actual usage requirements, depending on the actual situation of the energy used. For example, when the energy used is coal, its corresponding unit is kg; when the energy used is gasoline, its corresponding unit is liters (L); when the energy used is electric energy, its corresponding unit is kilowatt-hours (kWh), etc. The present disclosure does not make specific limitations; CEF e,i represents the carbon emission factor corresponding to the i-th type of energy, and its unit can be flexibly set according to actual usage requirements, depending on the actual situation of the energy used. For example, when the energy used is fossil energy, the unit of its corresponding carbon emission factor can be kilograms of carbon dioxide per ton of standard coal (kgCO 2 / tce), when the energy used is electric energy, the unit of its corresponding carbon emission factor can be kilograms of carbon dioxide per kilowatt-hour (kgCO 2 / kWh), etc. The present disclosure does not make specific limitations on this; E i represents the consumption of the i-th type of energy per unit time in the target plant-based building, and its unit can be flexibly set according to actual usage requirements, depending on the actual situation of the energy used and the unit time. For example, when the energy used is coal and the unit time is set to 1 year, its corresponding unit is kilograms per year (kg / yr); when the energy used is electric energy and the unit time is set to 1 year, its corresponding unit is kilowatt-hours per year (kWh / yr), etc. The present disclosure does not make specific limitations; SL b represents the expected service life corresponding to the target plant-based building, with the unit of yr.

[0125] After determining the embodied carbon emissions and operating carbon emissions corresponding to the target plant-based building through the foregoing process, the life-cycle carbon emissions corresponding to the target plant-based building can be determined. Specifically, the life-cycle carbon emissions corresponding to the target plant-based building can be expressed by formula (19):

[0126]

[0127] Among them, LCCO 2 represents the life-cycle carbon emissions corresponding to the target plant-based building, with the unit of kgCO 2 .

[0128] In the embodiments of the present disclosure, the embodied carbon emissions corresponding to the target plant-based building can be determined according to the life cycle stage corresponding to the target plant-based building, where the target plant-based building is constructed by at least one plant-based material, and the life cycle stage includes a carbon absorption stage, a carbon storage stage, a carbon transfer stage, and a carbon release stage. By dividing the entire life cycle stage of the target plant-based building based on the characteristics of the plant-based materials used in the target plant-based building itself as carbon carriers, and determining the corresponding carbon emissions for each life cycle stage corresponding to the target plant-based building, the process of determining the embodied carbon emissions corresponding to the target plant-based building can be simplified, the complexity of determining the embodied carbon emissions can be reduced, and the accuracy of the embodied carbon emissions can be improved. For the hygroscopic characteristics of the target plant-based building, the heat and moisture process of the target plant-based building can be simulated based on the coupled heat and moisture process model, so as to determine the building operation energy consumption corresponding to the target plant-based building, and then determine the operation carbon emissions, and improve the accuracy of the operation carbon emissions; according to the embodied carbon emissions and the operation carbon emissions, the total life cycle carbon emissions corresponding to the target plant-based building can be determined, and the total life cycle carbon emissions with high accuracy and reliability can be obtained.

[0129] It can be understood that the above-mentioned various method embodiments mentioned in the present disclosure can be combined with each other to form a combined embodiment without violating the principle logic.
