Description

Technical Field

[0001] The present application relates to the field of building materials technology, and in particular to a method and device for evaluating low-carbon technology for bulk building materials. Background Art

[0002] With the advancement of my country's full life cycle management and green manufacturing system, objective and scientific verification of carbon emissions of building materials is particularly important for energy conservation and emission reduction in the building materials industry. Accurate and scientific accounting of carbon emissions of building materials will also help the development of green and low-carbon building materials certification.

[0003] In the relevant technologies, there are few studies on the carbon emission accounting of bulk building materials throughout their life cycle, and carbon footprint data often refer to international data on similar products. For example, only the carbon emission accounting content and methods of a single building or a complex of buildings are specified. However, the classification level of building materials is still low and the completeness is poor. Moreover, this method does not fully cover the entire life cycle of building materials. For example, it does not specify the carbon fixation effect of cement during the operation phase. The concept of green and low-carbon building materials has been frequently mentioned in research in the past decade, but current researchers often define "low carbon" in a qualitative way, such as using a large amount of supplementary cementitious materials (SCM) and optimizing the mix ratio. The current carbon emission evaluation system is mainly used in industries where carbon emission policies are of high concern.

[0004] However, there are few studies on the full life cycle carbon emission accounting of bulk building materials in related technologies, which fail to fully cover the entire life cycle of bulk building materials. There is a lack of detailed greenhouse gas inventory analysis in the production, transportation, operation, recycling and other stages of building materials, and systematic carbon calculation applicable to the actual production process of building materials products; in addition, there are very few studies on carbon emissions of bulk building materials. Although there are a small number of carbon emission evaluation systems for the building materials field on the market, the specified standards are different due to different quantitative evaluation standards and scales. There is a lack of scientific evaluation methods for bulk building materials low-carbon technologies by comparing the carbon emissions calculated for a certain product with the general carbon emissions of this type of product. It is difficult to have a unified measurement indicator to comprehensively consider the performance of bulk building materials low-carbon technologies in many aspects, which needs to be solved urgently.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] The following describes the low-carbon technology evaluation method and device for bulk building materials in the embodiment of the present application with reference to the accompanying drawings. In view of the fact that there are few studies on the carbon emission accounting of bulk building materials products throughout their life cycle in the related technologies mentioned in the above background technology, there is a lack of detailed greenhouse gas inventory analysis in the stages of building materials production, transportation, operation, recycling, etc. and systematic carbon calculation applicable to building materials products in the actual production process; and, in view of the fact that the quantitative evaluation standards and scales of a small number of carbon emission evaluation systems in the field of building materials are different, there is a lack of a set of scientific evaluation methods and systems, and it is difficult to use carbon emissions and unified measurement indicators to comprehensively consider the performance of low-carbon technology of building materials in many aspects, the present application provides a low-carbon technology evaluation method for bulk building materials, in which the total carbon emissions of bulk building materials throughout their life cycle can be calculated, and then the scores of bulk building materials in multiple evaluation indicators are determined based on the total carbon emissions and the preset evaluation index system to determine the final score of low-carbon technology of bulk building materials. As a result, it is achieved through a detailed analysis of the production, transportation, operation, and recycling stages of bulk building materials, and a system carbon calculation function applicable to bulk building materials products in the actual production process is obtained, which ensures the accuracy of the calculation of the carbon emissions of bulk building materials at each stage and the carbon emissions of the entire life cycle, thereby ensuring accuracy; further, the present application can determine the corresponding carbon emission data set and comparison method through the comparison results of the calculated carbon emissions and general carbon emissions, thereby determining the priority of low-carbon technology for building materials, establishing a certain evaluation index system, and using the evaluation index system and the calculated carbon emissions to conduct a comprehensive evaluation of the performance of low-carbon technology for bulk building materials in terms of energy, economy, and energy consumption, effectively improving the accuracy and scientificity of the evaluation results of low-carbon technology for bulk building materials. This solves the problems that there are few studies on the carbon emission accounting of bulk building materials throughout their life cycle in related technologies, and there is a lack of detailed greenhouse gas inventory analysis and systematic carbon calculation applicable to the actual production process of building materials products during the production, transportation, operation, and recycling stages of building materials; as well as the lack of consistent quantitative evaluation standards and scales for the small number of carbon emission evaluation systems in the building materials field, and the lack of a scientific evaluation method and system, making it difficult to use carbon emissions and unified measurement indicators to comprehensively consider the performance of low-carbon building materials technologies in many aspects.

[0030] Before explaining the low-carbon technology evaluation method for bulk building materials in the embodiment of the present application, the framework of the low-carbon technology evaluation for bulk building materials in the embodiment of the present application is first explained.

[0031] Figure 1 This is a schematic diagram of the low-carbon technology evaluation framework for bulk building materials according to an embodiment of the present application. Figure 1 As shown, the low-carbon technology evaluation technology for bulk building materials in the embodiment of the present application is mainly from the basic unit of bulk building materials to the entire life cycle of bulk building materials, and then a comprehensive evaluation of the low-carbon technology of bulk building materials is performed.

[0032] Among them, the basic unit includes the information sources of carbon emission calculation data for bulk building materials, such as simulation or actual measurement, which can be determined according to different research objects based on regional differences in natural resources, energy structure, etc.

[0033] The entire life cycle first determines the entire life cycle process of bulk building materials from cradle (production) to grave (recycling), then determines the direct carbon emission intensity and indirect carbon emission intensity in each link and the output of each intermediate product and final product, and finally calculates the carbon emissions of the final product and each intermediate link.

[0034] After determining the entire life cycle, it can be applied to specific building materials to construct a method for calculating the carbon emissions of bulk building materials, thereby using carbon emissions to conduct a multi-dimensional comprehensive evaluation of the low-carbon technology of bulk building materials.

[0035] Among them, in the multi-dimensional comprehensive evaluation process, the embodiment of the present application mainly established a three-dimensional evaluation index system including energy consumption, economic cost and carbon emissions. The specific evaluation factors include but are not limited to the comprehensive cost of multi-dimensional comprehensive evaluation, energy cleanliness, carbon emissions reduction, etc.

[0036] Specifically, Figure 2 This is a flow chart of a low-carbon technology evaluation method for bulk building materials provided in an embodiment of the present application.

[0037] like Figure 2 As shown, the low-carbon technology evaluation method for bulk building materials includes the following steps:

[0038] In step S201, the total carbon emissions of bulk building materials over their entire life cycle are calculated based on the target measurement function of the bulk building materials over their entire life cycle.

[0039] In some embodiments, the overall carbon emissions of bulk building materials products in the entire life cycle are large, and emission reduction has become a key concern. Different low-carbon technologies used in bulk building materials in the entire life cycle have different effects on carbon emission reduction. Among them, low-carbon technology here refers to the technology and methods that can significantly reduce carbon emissions in the production, use and recycling of bulk building materials. These technologies are designed to optimize the energy efficiency of building materials, reduce greenhouse gas emissions in the production process, and improve the environmental performance and sustainability of building materials.

[0040] Based on this, when evaluating the low-carbon technology of bulk building materials, the embodiments of the present application can first calculate the total carbon emissions of bulk building materials over their entire life cycle based on the target measurement function of the entire life cycle of bulk building materials, which helps to evaluate the low-carbon technology of bulk building materials using the total carbon emissions.

[0041] For example, the target calculation function of the entire life cycle of bulk building materials in this application can be expressed as, but not limited to:

[0042] C=C SC +C ys +m 0 +C hs

[0043] Among them, C represents the total carbon emissions of bulk building materials throughout their life cycle, C SC represents the carbon emissions in the production of bulk building materials, C ys Represents the carbon emissions from the transportation of bulk building materials, m 0 represents the carbon emissions during the operation of bulk building materials, C hs Represents carbon emissions from the recycling stage of bulk building materials.

[0044] In this and subsequent descriptions of the embodiments of the present application, the unit of the calculation results is expressed in carbon dioxide emissions, i.e., kgCO 2 e.

[0045] Therefore, the embodiments of the present application can provide a basic understanding of the overall low-carbon technology of bulk building materials by calculating the overall carbon emissions of the bulk cycle over its entire life cycle.

[0046] Optionally, in one embodiment of the present application, the total carbon emissions of bulk building materials over their entire life cycle are calculated, including: calculating the carbon emissions generated by the bulk building materials in the production stage, transportation stage, operation stage, and recycling stage according to target measurement functions corresponding to the bulk building materials in the production stage, transportation stage, operation stage, and recycling stage; calculating the total carbon emissions of the bulk building materials over their entire life cycle according to the carbon emissions generated in the production stage, transportation stage, operation stage, and recycling stage, respectively, and the target measurement function.

[0047] Based on the relevant descriptions of other embodiments, it can be understood that the embodiments of this application can calculate the total carbon emissions of bulk building materials throughout their life cycle and have a basic understanding of the overall low-carbon technology of bulk building materials. Furthermore, in order to scientifically and accurately calculate the total carbon emissions of bulk building materials and thus improve the accuracy of the evaluation results of low-carbon technology of bulk building materials, this application can further analyze the carbon emissions of each stage in the entire life cycle of bulk building materials.

[0048] In certain embodiments, the embodiments of the present application can calculate the carbon emissions generated by bulk building materials in the production stage, transportation stage, operation stage and recycling stage according to the target measurement functions corresponding to the bulk building materials in the production stage, transportation stage, operation stage and recycling stage, thereby obtaining the total carbon emissions of the bulk building materials over their entire life cycle.

[0049] Among them, the target calculation function and carbon emissions at each stage in the embodiment of the present application can be expressed as follows but not limited to:

[0050] (1) Calculation function of carbon emissions in the production stage of bulk building materials:

[0051] In the embodiment of the present application, the carbon emissions in the bulk building materials production stage mainly include but are not limited to the total carbon emissions of all energy and materials consumed in the production of building materials. Therefore, the carbon emissions calculation function in the bulk building materials production stage can be expressed as but not limited to:

[0052]

[0053] Among them, C SC represents the carbon emissions in the production stage of bulk building materials, e represents the energy or materials consumed in the production stage of building materials, n represents the total types of energy or materials, M e,sc Indicates the amount of various energy or materials consumed in the production stage, F e Indicates the carbon emission factor corresponding to each energy or material.

[0054] (2) Calculation function of carbon emissions in the transportation stage of bulk building materials:

[0055] In the embodiment of the present application, the carbon emissions in the bulk building materials transportation stage are mainly considered from the energy consumption of vehicles transporting the purchased materials from the production site to the construction site. Therefore, the calculation function of the carbon emissions in the bulk building materials transportation stage can be, but is not limited to, expressed as:

[0056]

[0057] Among them, C ys represents the carbon emissions from the transportation of bulk building materials, m represents the total types of building materials in the transportation stage, and M j,ys represents the mass or volume of each building material j transported during the transportation phase, D j Indicates the transport distance, T j It represents the carbon emission factor per unit of building materials per unit of transportation distance.

[0058] (3) Calculation function of carbon emissions during the operation phase of bulk building materials:

[0059] In the embodiment of the present application, the carbon emissions during the operation stage of bulk building materials can be returned to the materials of the bulk building materials themselves. Considering that the carbonization of building materials is the main reason for the absorption of carbon dioxide, the carbon emissions of bulk building materials in this stage should be reported as reduced, and the carbon emissions take a negative value. Therefore, the calculation function of the carbon emissions during the operation stage of bulk building materials can be, but is not limited to, expressed as:

[0060] m 0 =fC,

[0061] Among them, m 0 Indicates that concrete absorbs CO 2 The amount of carbonization factor of building materials is , f is the carbonization factor of building materials, and C is the carbon emissions during the operation stage of bulk building materials.

[0062] The embodiments of the present application can improve the carbon emission measurement system of building materials throughout their life cycle by constructing a carbon emission target measurement function for each stage of the entire life cycle of bulk building materials, combining the basic data collected throughout the life cycle of bulk building materials with the carbon emission factors, making the carbon emission accounting results of bulk building materials more scientific and accurate, and improving the calculation accuracy of the total carbon emissions of bulk building materials throughout their life cycle and the carbon emissions at each stage, thereby being able to accurately and intuitively reflect the impact of carbon emissions on each stage of the entire life cycle of bulk building materials.

[0063] Optionally, in one embodiment of the present application, the carbon emissions generated by bulk building materials in the production stage, transportation stage, operation stage and recycling stage are calculated respectively according to the target measurement functions corresponding to the bulk building materials in the production stage, transportation stage, operation stage and recycling stage, including: calculating the carbon emissions of bulk building materials in the recycling and processing stage, the carbon emissions in the recycling and transportation stage, and the carbon emission reduction generated in the recycling stage according to the target measurement function of the bulk building materials in the recycling stage; determining the carbon emissions generated by bulk building materials in the recycling stage according to the carbon emissions in the recycling and processing stage, the carbon emissions in the recycling and transportation stage, and the carbon emission reduction.

[0064] Based on the relevant descriptions of other embodiments, it can be understood that the embodiments of the present application can, but are not limited to, divide the entire life cycle of bulk building materials into four stages: production stage, transportation stage, operation stage, and recycling stage. Among them, the target measurement functions and carbon emissions of the production stage, transportation stage, and operation stage have been explained above.

[0065] When calculating the carbon emissions in the recycling stage of bulk building materials, the embodiment of the present application mainly indirectly calculates the carbon emissions generated by bulk building materials in the recycling stage by calculating the carbon emissions in the recycling and processing stage, the carbon emissions in the recycling and transportation stage, and the carbon emissions reduction generated in the recycling stage.

[0066] It is understandable to those skilled in the art that in a given building, recyclable materials such as reinforcing bars, cables, steel, and plastic pipes are used. Studies have even shown that concrete can be recycled. Depending on the recycling equipment and technology, the recycling rate of building materials (bulk building materials) varies. The recycling rate should be calculated based on the ratio of the actual recycled mass to the mass of the raw materials.

[0067] That is to say, although a large amount of building materials are used in the construction process and a large amount of carbon emissions are generated in their production process, after the waste building materials are recycled, the carbon emissions reduced by the recycling of this part of the building materials are equivalent to entering a new life cycle. For the initial life cycle environmental impact, no carbon emissions are generated. Therefore, the embodiment of the present application can reduce the carbon emissions of the recycled and reused building materials.

[0068] Furthermore, when calculating the carbon emissions generated by bulk building materials in the recycling stage, the embodiment of the present application also takes into account the impact of secondary transportation and secondary processing on the carbon emissions in the recycling stage. In this process, they all have secondary carbon emissions. Therefore, the overall recycling stage carbon emission calculation function can be expressed as, but not limited to:

[0069]

[0070] Among them, C hs Represents the overall carbon emissions of the recycling stage, CCO 2e represents the carbon emission factor of the recycling equipment, s represents the total types of building materials in the recycling stage, M j,hs Indicates the mass or volume of each building material j recycled during the recycling stage; CK f M represents the carbon emission factor per unit transportation distance during the recycling process of the f-th building material. f,hs represents the mass or volume of building materials that need to be transported during the recycling phase, L f represents the recycling and transportation distance of the fth type of building materials; o represents the total types of building materials in the recycling and reuse stage, M k represents the recycling amount of the kth building material, η hs.k represents the recycling ratio of the k-th building material, F k Represents the carbon emission factor of the kth building material during the recycling and reuse process.

[0071] The above formula is divided into three parts, among which:

[0072] The first part is It refers to the carbon emissions generated by the secondary processing of recycled materials using mechanical equipment during the recycling process of building materials, that is, the carbon emission factor of the recycling equipment multiplied by the amount of recycled building materials.

[0073] The second part is This is the carbon emissions generated during the secondary transportation process, because the recycled materials are collected from the construction site to the recycling processing center and then to the sales market. This process also generates carbon emissions, that is, the carbon emission factor of transportation multiplied by the amount of recycled building materials and the transportation distance. It can be seen that the size of carbon emissions is proportional to the transportation distance. Therefore, within a certain range, the carbon emissions in the secondary transportation stage may exceed the carbon reduction of recycled building materials.

[0074] The third part is It is the carbon reduction generated after the recycling of building materials. Because this part of the recycled materials can flow back into the market after processing, it is equivalent to reducing the production of building materials in the next construction project. Therefore, this part can be determined according to the proportion of the recycling rate of different building materials to the carbon emissions of producing the material, and no specific limitation is made in the embodiments of the present application.

[0075] In summary, the energy consumed in the recycling of bulk building materials (converted into carbon emissions generated in the recycling stage) includes but is not limited to: secondary processing and transportation. In the embodiment of the present application, the carbon emissions of this part take a positive value; the recycling part is converted into carbon fixation. In the embodiment of the present application, the carbon emissions take a negative value.

[0076] Therefore, the embodiments of the present application can calculate the carbon emissions of each stage, such as the production stage, transportation stage, operation stage and recycling stage, and then calculate the total carbon emissions of the bulk building materials over their entire life cycle. By considering multiple influencing factors and actual scenarios, the calculation accuracy of the carbon emissions at each stage is improved while the calculation accuracy of the total carbon emissions of the bulk building materials over their entire life cycle is improved.

[0077] Step S202, based on the carbon emissions and the preset indicator system, obtain the secondary evaluation index score of the low-carbon technology of bulk building materials, and calculate the primary evaluation index score of the low-carbon technology of bulk building materials according to the secondary evaluation index score and its weight.

[0078] As a possible implementation method, after calculating the total carbon emissions of bulk building materials over their entire life cycle, the embodiments of the present application can achieve a multi-dimensional comprehensive evaluation of low-carbon technologies for bulk building materials based on the calculated total carbon emissions combined with energy, economy and other factors.

[0079] In the actual implementation process, this application can obtain the secondary evaluation index score of bulk building materials low-carbon technology based on the calculated total carbon emissions and the preset index system, and then calculate the primary evaluation index score of bulk building materials low-carbon technology based on the secondary evaluation index score and its weight, so as to determine the final evaluation result of bulk building materials low-carbon technology through the secondary evaluation index score and the primary evaluation index score. Among them, the preset index system here can be understood as a low-carbon technology evaluation index system with different characteristics of bulk building materials pre-established based on certain data information.

[0080] For example, when constructing a certain evaluation index system, the present application embodiment can first refer to relevant literature on technical evaluation by scholars, combine the greenhouse gas emission accounting method and reporting guidelines, and consider the CO2 emissions of different bulk building materials. 2 The characteristics of emissions are used to refine the factors affecting the selection of low-carbon technologies. For example, the factors affecting the selection of low-carbon technologies include but are not limited to natural factors, social factors, economic factors, and scientific and technological factors, while natural factors include natural conditions and natural resources, social factors include population factors and social history factors, economic factors include market factors and financial factors, and scientific and technological factors include technical level factors and technical constraints, etc. Next, the embodiment of the present application may, but is not limited to, use the Delphi method (expert survey method) to solicit expert opinions or conduct targeted literature research, so as to establish a low-carbon technology evaluation index system with the characteristics of different bulk building materials.

[0081] For example, the low-carbon technology evaluation index system for bulk building materials in the embodiment of the present application is a ladder-like structure consisting of a target layer (i.e., the evaluation results of the low-carbon technology of building materials), primary indicators, and secondary indicators. It can be, but is not limited to, composed of three primary evaluation indicators and eight secondary evaluation indicators, and conducts a comprehensive analysis and evaluation from three perspectives: energy, economy, and low-carbon effect. Among them, the primary indicators include energy evaluation indicators, economic indicators, and low-carbon effect evaluation indicators. The energy evaluation indicators also include two secondary indicators, namely, energy consumption and energy cleanliness; the low-carbon effect indicators include project CO 2 Total emission reduction, CO per unit of building materials product 2 The three secondary indicators are emission reduction rate, reduction in raw material consumption in the production process, etc. The economic evaluation indicators include three secondary indicators such as technology investment cost, technology equipment operation and maintenance cost, and technology equipment investment payback period, etc.

[0082] It should be noted that in the embodiments of the present application, the evaluation indicators used in the evaluation of low-carbon technology for bulk building materials include but are not limited to qualitative indicators and quantitative indicators. Among them, qualitative indicators refer to evaluation indicators that cannot be directly quantified and need to be quantified through other means. These indicators usually involve subjective judgments or feelings, so it is difficult to measure them with specific numerical values, such as energy effects, economic effects, low-carbon effects, etc. Quantitative indicators refer to assessment indicators that can be accurately defined in quantity, accurately measured, and can set performance goals, such as the primary evaluation indicators and secondary evaluation indicators in the embodiments of the present application.

[0083] After determining the evaluation index, the embodiment of the present application can calculate the first-level evaluation index score and the second-level evaluation index score respectively, thereby determining the comprehensive score of the low-carbon technology of bulk building materials.

[0084] The embodiments of the present application can go beyond the single low-carbon property, consider the characteristics of carbon emissions of bulk building materials, conduct a comprehensive evaluation from multiple aspects such as technical economy and energy consumption, calculate several three-dimensional primary and secondary indicators, and ensure the accuracy and scientificity of the evaluation of low-carbon technology for bulk building materials. It can provide a reference for the feasibility of low-carbon technology for bulk building material cement as an emission reduction measure.

[0085] Optionally, in one embodiment of the present application, based on the total carbon emissions and the preset indicator system, the secondary evaluation index score of the low-carbon technology of bulk building materials is obtained, and the first-level evaluation index score of the low-carbon technology of bulk building materials is calculated according to the secondary evaluation index score and its weight, including: based on the total carbon emissions and the preset indicator system, calculating the baseline values ​​of multiple basic evaluation indicators in the secondary evaluation index, and determining the secondary evaluation index score according to the baseline value; calculating the first-level evaluation index score in combination with the secondary evaluation index score and the weight of the secondary indicator.

[0086] Based on the relevant descriptions of other embodiments, it can be understood that the primary evaluation indicators and secondary evaluation indicators of energy, economy, and low-carbon effects involved in this application are all quantitative indicators. Based on this, in order to facilitate the calculation of the low-carbon technology level of each bulk building material, the embodiment of this application can also use the method of assigning basic points to each indicator to achieve normalization of the scores.

[0087] For example, the present application may use a percentage system to evaluate the primary evaluation indicators and the secondary evaluation indicators, where 10 points is a gradient. In the embodiment of the present application, it can be divided into but not limited to 4 gradients: 60 points, 70 points, 80 points and 90 points.

[0088] For the secondary evaluation indicators, the embodiments of the present application can, but are not limited to, use data obtained through literature research on bulk building materials technology to calculate the average value of multiple values ​​​​except the maximum value of low-carbon technology in the bulk building materials industry as the benchmark value of the secondary evaluation indicators, and derive the basic score of the low-carbon technology based on 1 / 4, 1 / 2, and 3 / 4 of the benchmark value, respectively.

[0089] For example, in the embodiment of the present application, it can be assumed that the greater the total carbon emission reduction value, the higher the score. At this time, the average value of the total carbon emission reduction of bulk building materials low-carbon technology is used as the benchmark value and is set to 90 points. When the total carbon emission reduction reaches 3 / 4 of the benchmark value, it can be set to 80 points, when it reaches 1 / 2 of the benchmark value, it can be set to 70 points, and when it reaches 1 / 4 of the benchmark value, it can be set to 60 points;

[0090] The larger the investment cost value, the lower the score. Taking the average investment cost of low-carbon building materials technology as the benchmark value and setting it to 60 points, when the investment cost reaches 3 / 4 of the benchmark value, it can be set to 70 points, when it reaches 1 / 2 of the benchmark value, it can be set to 80 points, and when it reaches 1 / 4 of the benchmark value, it can be set to 90 points.

[0091] It should be noted that the specific evaluation indicators and the principles for dividing their benchmark values ​​and scores can be selected or adjusted by professional and technical personnel in the field according to actual conditions. They are only used for illustrative purposes here without specific limitations.

[0092] After calculating the scores of all secondary evaluation indicators, the embodiment of the present application can calculate the scores of the primary evaluation indicators based on the secondary evaluation indicators and the weights of the secondary evaluation indicators. The final evaluation result can be determined based on but is not limited to the three primary indicators and the weights of the primary indicators.

[0093] Optionally, in one embodiment of the present application, before calculating the first-level evaluation index score of bulk building materials low-carbon technology based on the second-level evaluation index score and its weight, it also includes: based on a preset index system, determining the hierarchical relationship and attribution relationship between the first-level evaluation index and the second-level evaluation index; based on the hierarchical relationship and the attribution relationship, constructing a judgment matrix and normalizing the judgment matrix to obtain the characteristic roots of the judgment matrix, so as to determine the weights of the second-level indicators and the weights of the first-level indicators respectively through the characteristic roots.

[0094] Based on the relevant descriptions of other embodiments, it can be understood that when calculating the score of the first-level evaluation index, the embodiment of the present application can determine the first-level index score based on the second-level evaluation index score and its weight, and the final bulk building materials low-carbon technology evaluation needs to be calculated based on the first-level index score and its weight. Therefore, the embodiment of the present application can also calculate the weight of the second-level evaluation index and the weight of the first-level evaluation index.

[0095] In some embodiments, the embodiments of the present application may, but are not limited to, use the analytic hierarchy process to determine the weights of various evaluation indicators. The analytic hierarchy process is a simple arbitrary calculation principle and a standard tool for assigning weights to compare other parameters / alternatives. This analysis method can provide a powerful model for decision-making, rating, and prioritization problems.

[0096] In the embodiment of the present application, the specific application process of the hierarchical analysis method can be, but is not limited to, expressed as follows:

[0097] First, the embodiment of the present application may, but is not limited to, compare each secondary evaluation index factor in pairs through literature research, and construct a corresponding judgment matrix according to the importance of the two factors by the 1-9 scaling method to calculate the characteristic vector, and then perform a total ranking to assist in decision making. Specifically, the steps for determining the index weight may, but are not limited to, be expressed as follows:

[0098] (1) Constructing the evaluation structure: through the established indicator system structure, determine the hierarchy and attribution relationship of the first-level evaluation indicators and the second-level evaluation indicators, and represent the first-level evaluation indicators and the second-level evaluation indicators of the indicator system as A and B respectively;

[0099] (2) Constructing a judgment matrix: The importance of each secondary evaluation indicator can be judged pairwise through literature research and actual work experience, and the judgment matrix A[A = (a ij ) m×n ];

[0100] (3) Normalization of the judgment matrix: Since there are many normalization methods, the present embodiment only uses the square root method to illustrate, that is, first calculate the product M of each row element of the judgment matrix i , then calculate M i The nth root of And find out Finally, the normalization process is performed to obtain the characteristic root;

[0101] (4) Perform consistency check: First, approximately calculate the maximum characteristic root λ max , and then perform a consistency check.

[0102] It should be noted that, in the actual operation process, the judgment principle of the importance of the indicator, the normalization method, etc., can be selected or adjusted by professional and technical personnel in this field according to the actual situation. This is only an exemplary description without specific limitation. In order to facilitate calculation, the embodiment of the present application can also, but not limited to, use certain computing tools such as Matlab software or other scientific computing software to select the algorithm of judgment matrix aggregation and average weight to calculate the weights of the primary evaluation indicators and the secondary evaluation indicators.

[0103] Step S203, calculating the score of the low-carbon technology for bulk building materials according to the score of the secondary evaluation index and its weight and the score of the primary evaluation index and its weight.

[0104] In other embodiments, after the secondary evaluation index score of the low-carbon technology on the secondary scoring index is determined by the benchmark value and recorded as S′, the secondary evaluation index score can be multiplied by the respective weights W′ and then added to obtain the corresponding primary evaluation index score and recorded as S. Finally, each primary evaluation index score is multiplied by the corresponding weight W and summed, and the comprehensive score of the low-carbon technology of bulk building materials can be obtained, which can be expressed by the calculation formula but not limited to the following:

[0105]

[0106] Among them, H is the comprehensive score of low-carbon technology, W′ is the weight of each secondary indicator, W is the weight of each primary indicator, S′ is the basic score of low-carbon technology on the secondary indicator, that is, the secondary evaluation indicator score, and S is the score of the corresponding primary indicator.

[0107] It should be noted that in the embodiments of the present application, the overall low-carbon technology of bulk building materials is evaluated based on the total carbon emissions of bulk building materials throughout their life cycle. However, in actual application, the low-carbon technology of each stage can also be evaluated according to the carbon emissions of each stage in the whole life cycle of bulk building materials, or a comprehensive evaluation can be conducted on the low-carbon technology of any several stages, etc. This is only an illustrative explanation without specific limitation.

[0108] The embodiments of the present application can evaluate the economic benefits and carbon reduction effects of different low-carbon technologies for bulk building materials by quantitatively calculating the key evaluation indicators of bulk building materials. By comparing and selecting different low-carbon technologies through these evaluation indicators, it is possible to accurately describe the operation process of the technology, the generation and change of carbon emissions, the calculation of economic costs, etc., and can record and track the key information such as the use of low-carbon technologies for bulk building materials, carbon emissions, and economic costs, so as to have a deeper understanding of the performance and potential of low-carbon technologies, and help the bulk building materials industry to select low-carbon technologies according to actual needs.

[0109] According to the low-carbon technology evaluation method for bulk building materials proposed in the embodiment of the present application, the total carbon emissions of bulk building materials in the whole life cycle can be calculated, and then the scores of bulk building materials in multiple evaluation indicators are determined based on the total carbon emissions and the preset evaluation index system to determine the final score of the low-carbon technology of bulk building materials. Thus, a system carbon calculation function suitable for bulk building materials products in the actual production process is obtained by conducting a detailed analysis of the production, transportation, operation, and recycling stages of bulk building materials, thereby ensuring the accuracy of the calculation of the carbon emissions of bulk building materials at each stage and the carbon emissions of the whole life cycle, thereby ensuring the accuracy; further, the present application can determine the corresponding carbon emissions data set and comparison method through the comparison results of the calculated carbon emissions and the general carbon emissions, thereby determining the priority of the low-carbon technology of building materials, establishing a certain evaluation index system, and using the evaluation index system and the calculated carbon emissions to comprehensively evaluate the performance of the low-carbon technology of bulk building materials in terms of energy, economy, and energy consumption, effectively improving the accuracy and scientificity of the evaluation results of the low-carbon technology of bulk building materials. This solves the problems that there are few studies on the carbon emission accounting of bulk building materials throughout their life cycle in related technologies, and there is a lack of detailed greenhouse gas inventory analysis and systematic carbon calculation applicable to the actual production process of building materials products during the production, transportation, operation, and recycling stages of building materials; as well as the lack of consistent quantitative evaluation standards and scales for the small number of carbon emission evaluation systems in the building materials field, and the lack of a scientific evaluation method and system, making it difficult to use carbon emissions and unified measurement indicators to comprehensively consider the performance of low-carbon building materials technologies in many aspects.

[0128] It should be noted that the aforementioned explanation of the embodiment of the low-carbon technology evaluation method for bulk building materials is also applicable to the low-carbon technology evaluation device for bulk building materials of this embodiment, and will not be repeated here.

[0129] According to the low-carbon technology evaluation device for bulk building materials proposed in the embodiment of the present application, the total carbon emissions of bulk building materials in the whole life cycle can be calculated, and then the scores of bulk building materials in multiple evaluation indicators are determined based on the total carbon emissions and the preset evaluation index system to determine the final score of the low-carbon technology of bulk building materials.
