[0026] 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 accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0027] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0028] The term "and / or" herein is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the term "at least one" herein represents any combination of at least two of any one or more of a plurality of. For example, including at least one of A, B, and C can represent including any one or more elements selected from the set consisting of A, B, and C.

[0029] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0030] Building carbon emissions can represent the greenhouse gas emissions generated by buildings during their construction, demolition and operation stages. Building carbon emissions usually include embodied carbon emissions and operational carbon emissions; among them, embodied carbon emissions can represent the carbon emissions generated by activities such as the production, transportation, construction and demolition of building materials, mainly from the production of building materials; operational carbon emissions can represent the total carbon emissions of a building during its entire use period (i.e. from the completion of construction to demolition).

[0031] The existing methods for calculating the embodied carbon emissions of buildings usually focus on the carbon emissions of bulk building materials. It is necessary to use the corresponding consumption of various building materials and the carbon emission factors corresponding to each building material to determine the embodied carbon emissions of buildings. For cast-in-place building systems that are directly cast and constructed using building materials, such as cast-in-place concrete buildings, the corresponding embodied carbon emissions can be directly calculated based on the amount of building materials used and the carbon emission factors corresponding to the building materials. However, the construction process corresponding to prefabricated buildings is different from that of cast-in-place buildings.

[0032] Figure 1 A schematic diagram showing the construction process of a cast-in-place building and a prefabricated building according to the prior art. Figure 1 As shown, the construction process of cast-in-place buildings mainly includes: the production process of building materials, the transportation process of building materials and the cast-in-place construction process; the construction process of prefabricated buildings mainly includes: the production process of building materials, the prefabrication process of building components, the transportation process of building components and the building assembly process.

[0033] Since prefabricated buildings involve the prefabrication of building components, and there are significant differences between the cast-in-place construction process and the building assembly process, if the embodied carbon emissions of prefabricated buildings are calculated directly based on building materials, there will be problems such as cumbersome calculation process, large calculation workload and inaccurate calculation results.

[0034] On the other hand, prefabricated buildings have high design flexibility. In actual application, the design scheme of prefabricated buildings may be adjusted and optimized many times in multiple stages such as project planning, conceptual design, scheme design, preliminary design, construction drawing design and budget control. It is difficult to obtain an accurate list of building materials, which further increases the difficulty of determining the embodied carbon emissions of prefabricated buildings and reduces the efficiency of determining the embodied carbon emissions of prefabricated buildings.

[0035] In view of this, the embodiment of the present disclosure provides a method for constructing an embodied carbon emission database for prefabricated buildings, which can construct an embodied carbon emission database for prefabricated buildings based on the hierarchical relationship of materials-components-building systems, and can provide comprehensive carbon emission reference data for evaluating the embodied carbon emissions corresponding to the target prefabricated buildings for different application scenarios and construction engineering stages, thereby simplifying the calculation process and improving the calculation efficiency. The method for constructing an embodied carbon emission database for prefabricated buildings provided by the present disclosure is described in detail below.

Alternatively, the method for constructing a database of embodied carbon emissions of a prefabricated building can be executed by a server. Figure 2 As shown, the method for constructing the embodied carbon emission database of the prefabricated building includes:

[0037] In step S201, first reference carbon emission factors corresponding to a plurality of basic building materials are determined.

[0038] The basic building materials here can refer to materials used for building construction made of at least one raw material. The specific form can be flexibly set according to actual use requirements. For example, it can be materials such as cement, sand, lime, wood, steel bars and concrete components, as well as additional materials such as adhesives and paints. The present disclosure does not make specific restrictions on this.

Among them, the specific content of the raw materials can be flexibly set according to actual use requirements, depending on the specific form of the basic building materials. For example, when the basic building material is steel bars, the raw materials may include steel, etc., and the present disclosure does not make specific restrictions on this.

[0039] The first reference carbon emission factor corresponding to any basic building material can represent the carbon emissions generated by manufacturing the basic building material, and can reflect the greenhouse effect caused by the basic building material. The unit form of the first reference carbon emission factor can refer to the implementation in the relevant technology, depending on the specific form of the basic building material. For example, when the basic building material is cement, its corresponding first reference carbon emission factor can be expressed as kilograms of carbon dioxide per kilogram (kgCO2 / kg), and the present disclosure does not make specific limitations on this.

[0042] In step S202, second reference carbon emission factors corresponding to a plurality of target assembly components are determined according to first reference carbon emission factors corresponding to a plurality of basic building materials, wherein any target assembly component represents a prefabricated building component manufactured from at least one basic building material.

[0043] Any target assembly component may represent a prefabricated building component and accessory made of at least one basic building material, and its specific form may be flexibly set according to actual use requirements, for example, it may be a building exterior wall, roof, floor slab, and interior partition wall in the form of a prefabricated part, and the present disclosure does not make specific restrictions on this. The specific number of target assembly components may be flexibly set according to actual use requirements, and the present disclosure does not make specific restrictions on this.

[0044] The second reference carbon emission factor corresponding to any target assembly component can represent the carbon emission generated by manufacturing the target assembly component, and can reflect the greenhouse effect caused by the target assembly component. The unit form of the second reference carbon emission factor can refer to the implementation in the relevant technology, depending on the specific form of the target assembly component, and the present disclosure does not make specific limitations on this.

[0045] For any target assembly component, the second reference carbon emission factor corresponding to the target assembly component is determined according to the basic building materials required to manufacture the target assembly component and its corresponding first reference carbon emission factor. The specific method of determining the second reference carbon emission factor can be flexibly set according to actual usage requirements, and this disclosure does not specifically limit this.

[0046] The process of determining the second reference carbon emission factors corresponding to a plurality of target assembly components according to the first reference carbon emission factors corresponding to a plurality of basic building materials will be described in detail later in conjunction with possible implementation methods of the present disclosure, which will not be elaborated here.

[0047] In step S203, a third reference carbon emission factor corresponding to a sample prefabricated building is determined based on first reference carbon emission factors corresponding to a plurality of basic building materials and second reference carbon emission factors corresponding to a plurality of target assembly components, wherein the sample prefabricated building refers to a prefabricated building constructed of at least one target assembly component.

[0048] The sample prefabricated building may refer to a prefabricated building constructed based on at least one target assembly component, and its specific form may be flexibly set according to actual use requirements, for example, it may include a block building, a plate building, a box-type building, a skeleton plate building, and a lifting plate and lifting floor building, etc., and the present disclosure does not make specific restrictions on this. The specific number of the sample prefabricated buildings may be flexibly set according to actual use requirements, and the present disclosure does not make specific restrictions on this.

[0049] The specific method of determining the sample prefabricated building can be flexibly set according to actual usage requirements. For example, common prefabricated buildings can be selected as sample prefabricated buildings based on statistical data, and the present disclosure does not make specific limitations on this.

[0050] The third reference carbon emission factor corresponding to the sample prefabricated building can represent the carbon emissions generated by building the sample prefabricated building, and can reflect the greenhouse effect caused by the sample prefabricated building. The unit form of the third reference carbon emission factor can be flexibly set according to actual usage requirements, and the present disclosure does not make specific limitations on this. The third reference carbon emission factor corresponding to the sample prefabricated building can be determined based on the target building components and basic building materials required to build the sample prefabricated building.

[0051] The following text will describe in detail the process of determining the third reference carbon emission factor corresponding to the sample prefabricated building based on the first reference carbon emission factors corresponding to a variety of basic building materials and the second reference carbon emission factors corresponding to a variety of target assembly components in combination with possible implementation methods of the present disclosure, which will not be elaborated here.

[0052] In step S204, an embodied carbon emission database is determined based on a first reference carbon emission factor corresponding to a plurality of basic building materials, a second reference carbon emission factor corresponding to a plurality of target assembly components, and a third reference carbon emission factor corresponding to a sample prefabricated building, wherein the embodied carbon emission database is used to evaluate the building embodied carbon emissions corresponding to the target prefabricated building.

[0053] According to the hierarchical relationship of basic building materials-target assembly components-sample prefabricated buildings, according to the first reference carbon emission factors corresponding to various basic building materials, the second reference carbon emission factors corresponding to various target assembly components, and the third reference carbon emission factors corresponding to sample prefabricated buildings, an implicit carbon emission database for prefabricated buildings can be constructed, so as to provide comprehensive carbon emission reference data for different application scenarios and construction engineering stages, and can quickly and accurately evaluate the building implicit carbon emissions corresponding to the target prefabricated building. There is no need to calculate the building implicit carbon emissions corresponding to the target prefabricated building from the raw material stage, which can simplify the calculation process and improve the calculation efficiency and accuracy of the calculation results. Among them, the specific form of the implicit carbon emission database can be flexibly set according to actual use requirements, and this disclosure does not make specific limitations on this.

[0054] Based on the first reference carbon emission factor, the second reference carbon emission factor or the third reference carbon emission factor in the embodied carbon emission database, the embodied carbon emissions of prefabricated buildings can be directly calculated. For example, before constructing the target prefabricated building, according to the design scheme corresponding to the target prefabricated building, the embodied carbon emissions of the building can be quickly estimated through the third reference carbon emission factor and the building area, or the embodied carbon emissions of the building can be quickly calculated through the second reference carbon emission factor and the component usage; after the target prefabricated building is built, according to the project list corresponding to the target prefabricated building, the embodied carbon emissions of the building can be accurately calculated through the first reference carbon emission factor and the material usage, etc. It can be flexibly set according to the actual use requirements, and the present disclosure does not make specific restrictions on this.

[0055] Figure 3 A schematic diagram showing a design process of a target prefabricated building according to an embodiment of the present disclosure is shown. Figure 3 As shown, the design process of the target prefabricated building can include the initial planning and design stage, the component selection stage and the construction design stage.

[0056] In the initial planning and design stage of the target prefabricated building, the building embodied carbon emissions corresponding to the target prefabricated building can be estimated based on the conceptual design and project scale corresponding to the target prefabricated building, combined with the third reference carbon emission factor corresponding to the sample prefabricated building in the embodied carbon emission database, to assist in adjusting the design plan of the target prefabricated building.

[0058] During the construction design stage of the target prefabricated building, the accuracy of the building embodied carbon emissions corresponding to the target prefabricated building can be further improved based on budget control requirements and project lists, combined with the first reference carbon emission factor corresponding to the basic building materials in the embodied carbon emission database, so as to make detailed adjustments to the construction drawings of the target prefabricated building.

[0059] The following text will describe in detail the process of determining the implicit carbon emission database based on the first reference carbon emission factors corresponding to multiple basic building materials, the second reference carbon emission factors corresponding to multiple target assembly components, and the third reference carbon emission factors corresponding to the sample prefabricated buildings, in combination with possible implementation methods of the present disclosure, which will not be elaborated here.

[0060] In the embodiment of the present disclosure, by determining the first reference carbon emission factors corresponding to a plurality of basic building materials; the second reference carbon emission factors corresponding to a plurality of target assembly components can be determined according to the first reference carbon emission factors corresponding to the plurality of basic building materials, wherein any target assembly component represents a prefabricated building component manufactured from at least one basic building material; and then the third reference carbon emission factor corresponding to the sample prefabricated building can be determined according to the first reference carbon emission factors corresponding to the plurality of basic building materials and the second reference carbon emission factors corresponding to the plurality of target assembly components, wherein the sample prefabricated building represents a prefabricated building constructed from at least one target assembly component. According to the first reference carbon emission factors corresponding to various basic building materials, the second reference carbon emission factors corresponding to various target assembly components, and the third reference carbon emission factors corresponding to the sample prefabricated buildings, the embodied carbon emission database is determined, wherein the embodied carbon emission database is used to evaluate the building embodied carbon emissions corresponding to the target prefabricated buildings, thereby realizing the construction of an embodied carbon emission database for prefabricated buildings based on the hierarchical relationship of the material-component-building system. It can provide comprehensive carbon emission reference data for evaluating the embodied carbon emissions corresponding to the target prefabricated buildings for different application scenarios and construction project stages, which can simplify the calculation process and improve the calculation efficiency and the accuracy of the calculation results.

[0061] In one possible implementation, first reference carbon emission factors corresponding to a plurality of basic building materials are determined, including: for any one basic building material, according to the processing process corresponding to the basic building material, a first process list corresponding to the basic building material is determined, wherein the first process list corresponding to any one basic building material includes the types and consumption of raw materials and energy required to manufacture the basic building material; for any one basic building material, according to the first process list corresponding to the basic building material, a first reference carbon emission factor corresponding to the basic building material is determined.

M and energy flow f E The process analysis (PA) is performed to determine the first process list corresponding to the basic building material, so as to accurately calculate the first reference carbon emission factor corresponding to the basic building material. The first process list corresponding to any basic building material may include the types and consumption of raw materials and energy required to manufacture the basic building material. The specific form can be flexibly set according to actual usage requirements, and the present disclosure does not make specific limitations on this.

[0063] For any basic building material, the specific method of the first process list corresponding to the basic building material can be determined according to the processing process corresponding to the basic building material, and can be flexibly set according to actual usage requirements.

[0067] Specifically, felling tools and vehicles are needed during the raw bamboo felling and transportation stage, thereby consuming fossil energy such as gasoline and natural gas; during the decomposition stage, the raw bamboo materials obtained from felling need to be decomposed into bamboo strip units, which requires the consumption of electric energy; the pretreatment stage usually includes three-proof treatment (anti-corrosion, anti-mildew and anti-termite), bleaching, carbonization, drying and standardization treatment of the bamboo strip units obtained in the decomposition stage, which requires the consumption of electric energy and fossil energy, as well as related chemicals; in the single-layer board pressing stage, including gluing, assembly and flat pressing / side pressing of the pretreated bamboo strip units, which requires the consumption of electric energy and adhesives; in the three-layer board pressing stage, including gluing and flat pressing, which requires the consumption of electric energy and adhesives; in the post-processing stage, including trimming, polishing and painting, which requires the consumption of electric energy and paint.

[0068] For any stage in the processing of the three-layer bamboo integrated board, the first process list corresponding to the three-layer bamboo integrated board can be determined by counting the consumption of raw materials and energy in this stage.

[0069] For any basic building material, the first reference carbon emission factor corresponding to the basic building material can be determined according to the first process list corresponding to the basic building material. Specifically, according to the first process list corresponding to the basic building material, the carbon emissions generated by manufacturing a unit quantity of the basic building material can be determined as the first reference carbon emission factor corresponding to the basic building material. The specific form of the unit quantity can be flexibly set according to actual usage requirements, depending on the specific form of the basic building material. For example, when the basic building material is a three-layer bamboo integrated board, the unit quantity can be set to 1 kilogram (kg) or 1 square meter (m 2 ), etc., and the present disclosure does not make any specific limitation on this.

[0070] In a possible implementation, second reference carbon emission factors corresponding to multiple target assembly components are determined based on first reference carbon emission factors corresponding to multiple basic building materials, including: for any target assembly component, a second process list corresponding to the target assembly component is determined based on the manufacturing standard corresponding to the target assembly component, wherein the second process list corresponding to any target assembly component includes the types and consumption of basic building materials and energy required to manufacture the target assembly component; for any target assembly component, a second reference carbon emission factor corresponding to the target assembly component is determined based on the second process list corresponding to the target assembly component and the first reference carbon emission factors corresponding to multiple basic building materials.

[0071] For any target assembly component, the carbon emission data of the manufacturing process of the target assembly component can be statistically analyzed from the two aspects of material consumption and energy consumption based on the manufacturing standard corresponding to the target assembly component, so as to realize material flow analysis at the component level. M and energy flow f E The process analysis is performed to determine the second process list corresponding to the target assembly component, so as to accurately calculate the second reference carbon emission factor corresponding to the target assembly component.

The specific method of determining the manufacturing standard corresponding to any target assembly component can be flexibly set according to actual usage requirements, and the present disclosure does not make specific limitations on this.

[0073] In one example, the manufacturing standard corresponding to each target assembly component can be determined based on the commonly used construction drawings of prefabricated buildings in combination with industry standards.

[0074] The second process list corresponding to any target assembly component may include the types and consumption of basic building materials and energy required to manufacture the target assembly component. Its specific form can be flexibly set according to actual usage requirements and depends on the specific form of the target assembly component. The present disclosure does not make specific limitations on this.

[0075] For any target assembly component, the second reference carbon emission factor corresponding to the target assembly component can be determined according to the second process list corresponding to the target assembly component.
