Technical Field

[0001] The present invention belongs to the technical field of carbon emission accounting, and specifically relates to a method and system for intelligently controlling carbon emissions during the construction phase of a building project. Background Art

[0002] At present, existing energy conservation and carbon reduction work and research in the construction industry are mainly concentrated on the operation stage of large public buildings. For example, active and passive technologies are used in the design and planning stages to reduce energy consumption during the operation period of buildings. However, the above-mentioned research focuses on energy conservation and carbon reduction in the construction industry, especially in the construction stage of building projects. There is little research on carbon emission accounting methods applicable to the construction stage of building projects, and it is difficult to quantitatively evaluate low-carbon construction. At the same time, there is a lack of methods for actively regulating low-carbon construction in the construction stage of building projects. Summary of the invention

[0015] Furthermore, a method for intelligent control of carbon emissions during the construction phase of a building project also includes: establishing carbon emission assessment standards for the construction phase of the building project in advance; wherein the carbon emission assessment standards are used to assess the overall low-carbon construction level, including four levels of assessment indicators: excellent, good, passing, and poor.

[0016] Furthermore, if the calculated overall low-carbon construction level is lower than the expected level, the corresponding carbon reduction measures are taken according to the level difference to intelligently adjust the actual carbon emissions of the next project sub-item, including:

[0018] After the actual completion of the i-th project sub-item, determine whether the calculated overall low-carbon construction level is lower than the expected level;

[0019] If the result of the judgment is that the calculated overall low-carbon construction level is lower than the expected level, the difference between the overall low-carbon construction level and the expected level is calculated to obtain the level difference; if the expected level is a range of values, the minimum value in the expected level is taken for the level difference calculation;

[0020] Retrieve various carbon reduction measures that can be used for the i+1 project sub-item in the carbon reduction measures library, and obtain the quantified carbon reduction effect of each carbon reduction measure;

[0021] According to the level difference, determine the carbon reduction effect of the i+1 project sub-item demand ;in, Satisfy the first inequality;

[0022] The first inequality is:

[0036] If the second judgment result is not higher than the preset second normal value range, a weight is assigned to the corresponding target sub-item.

[0038] Obtain the first leading person of the abnormal small project, and determine whether the current accumulated project abnormality rate of the first leading person exceeds the preset abnormality threshold;

[0039] If the judgment result is that the project abnormality rate exceeds the preset abnormality threshold, all small projects that the first leading person in the subsequent engineering sub-items that have not yet been constructed are responsible for are obtained, and a small project set is obtained;

[0040] Retrieve all idle leading personnel and corresponding historical project leading information in the database, and calculate the first similarity between the historical project leading information corresponding to each leading personnel and the small project set;

[0041] The leading personnel corresponding to the leading information of the historical projects whose first similarity is greater than the preset similarity threshold are obtained as the second leading personnel, and the suitability of each second leading personnel to the current construction project is calculated based on the priority indexes of all the second leading personnel; wherein the priority index is related to the project abnormality rate, and the higher the abnormality rate of the historical projects, the lower the priority index;

[0042] The second leading person with the highest adaptability is selected as the target leading person, and the historical project leading information, similarity information, priority index and adaptability of the target leading person are extracted to generate a recommendation list, which is then fed back to the backend management personnel.

[0056] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0057] like Figure 1 As shown, the present invention proposes a method for intelligently controlling carbon emissions during the construction phase of a building project, comprising:

[0058] S101. According to the estimated construction progress and construction plan of the building project, the project is divided into items to obtain multiple project items;

[0059] S102, estimating carbon emissions for each project item based on traditional construction plans and processes to obtain multiple estimated carbon emissions;

[0060] S103. After each project sub-item is actually completed, the actual carbon emissions of the completed project sub-items are collected and combined with the corresponding estimated carbon emissions to calculate the overall low-carbon construction level of the current construction stage;

[0061] S104. If the calculated overall low-carbon construction level is lower than the expected level, the corresponding carbon reduction measures are taken according to the level difference to intelligently adjust the actual carbon emissions of the next project sub-item;

[0062] The working principle of the above technical solution is as follows: This solution mainly includes two control processes, one is to calculate the estimated carbon emission data before the project is implemented, and the other is to calculate the actual carbon emission data during the construction of the project and to adjust the unqualified carbon emission data in real time to make it meet the preset carbon emission standards;

[0063] In the first stage, before the project is implemented, the current project is divided into multiple sub-items according to the construction plan and the estimated progress of the construction of this project. Then, according to the estimated progress of the construction of the project and the traditional construction plan and process, the carbon emissions of each sub-item of the construction of this project are estimated, and the estimated carbon emissions of sub-item 1, sub-item 2 and subsequent sub-items until the last sub-item L are estimated. Each sub-item corresponds to a construction implementation stage. In this process, the calculation sources of the estimated carbon emissions include carbon emissions from building materials production, transportation, construction, etc., and all sub-items have an implementation order, that is, the next sub-item can only be implemented after the previous sub-item is implemented. It is worth noting that there can be multiple sub-items implemented in parallel;

[0064] When the first stage is completed, that is, the pre-construction data has been processed, the second stage of carbon emission control begins. First, it is necessary to clarify the current project sub-item stage (it is worth noting that, usually, the current project sub-item stage is the first stage when the second stage begins). Taking the first project sub-item as an example, after its actual completion, the actual carbon emissions of the completed project sub-item are collected (since it is the first project sub-item, the actual carbon emissions here are the actual carbon emissions of the first project sub-item), and the overall low-carbon construction level of the current construction stage is calculated in combination with the corresponding estimated carbon emissions; the calculation sources of the actual carbon emissions include carbon emissions from building materials production, transportation, construction, etc.; this step is used to finely quantify each construction stage, determine the overall low-carbon construction level of each construction stage, and can obtain and independently display the actual carbon emissions of each construction stage;

[0065] Taking the i-th engineering sub-item as an example, after its actual completion, the actual carbon emissions of the completed engineering sub-items are collected (since it is the i-th engineering sub-item, the actual carbon emissions here are the sum of all actual carbon emissions from the first engineering sub-item to the i-th engineering sub-item), and the overall low-carbon construction level of the current construction stage is calculated in combination with the corresponding estimated carbon emissions (corresponding to the engineering sub-item sequence and quantity associated with the actual carbon emissions); wherein, this step is used to finely quantify the completed construction stage, determine the overall low-carbon construction level of the constructed stage, and can obtain and independently display the actual carbon emissions of the constructed stage;

[0066] Furthermore, taking the i-th engineering sub-item as an example, after its actual completion, the actual carbon emissions of the completed engineering sub-item are collected (furthermore, the actual carbon emissions here can be the actual carbon emissions of the i-th engineering sub-item), and the stage low-carbon construction level of the current construction stage is calculated in combination with the corresponding estimated carbon emissions; wherein, this step is used to finely quantify the corresponding stage of any engineering sub-item in the construction stage, determine the stage low-carbon construction level of any construction stage, and can obtain and independently display the actual carbon emissions of any construction stage;

[0067] At the same time, the overall low-carbon construction level obtained for the construction stage corresponding to any engineering sub-item can be evaluated and regulated. For example, if the overall low-carbon construction level calculated for any construction stage is lower than the expected level, the corresponding carbon reduction measures are called according to the level difference to intelligently regulate the actual carbon emissions of the next engineering sub-item, including automatically calling one or more combined measures in the relevant carbon reduction library module to ensure that the regulation target is achieved; this step is used to actively regulate the carbon emissions of any construction stage, and realize the intelligent management and control of carbon emissions throughout the life cycle of the construction stage;

[0068] The beneficial effect of the above technical solution is: through the above technical solution, a full-process quantitative and refined control method is established during the construction phase of a building project, which is used to solve the problem that carbon emissions cannot be finely quantified during the construction phase of traditional building projects, and carbon emissions cannot be actively regulated during the construction phase.

[0069] In one embodiment, a method for intelligently controlling carbon emissions during the construction phase of a building project further includes: establishing in advance a carbon reduction measures library applicable to various stages of various types of building projects; wherein the carbon reduction measures library covers carbon reduction measures for low-carbon materials, low-carbon construction techniques, low-carbon energy, carbon sinks, and photovoltaic systems on construction sites, and each carbon reduction measure can quantify its carbon reduction effect;

[0070] The working principle and beneficial effects of the above technical solution are as follows: In order to achieve the second stage of carbon emission control, this application also proposes a method for establishing a carbon reduction measures library, which is based on methods including but not limited to big data technology to obtain in advance various carbon reduction measures covering low-carbon materials, low-carbon construction processes, low-carbon energy, carbon sinks, construction site photovoltaic systems, etc., and uses a preset quantification method to quantify the carbon reduction effect of each carbon reduction measure. The quantified result can be the carbon reduction per unit area; by establishing a quantifiable carbon reduction measures library corresponding to each construction implementation stage of the construction project, relevant measures can be called up according to carbon reduction needs during the construction process to solve the problem that traditional carbon reduction work cannot be quantified.

[0071] In one embodiment, after each engineering sub-item is actually completed, the actual carbon emissions of the completed engineering sub-items are collected and combined with the corresponding estimated carbon emissions to calculate the overall low-carbon construction level of the current construction stage, including:

[0072] After the actual completion of the i-th project sub-item, collect the actual carbon emissions of the i-th project sub-item , and obtain the actual carbon emissions of all completed engineering sub-items before the i-th engineering sub-item , calculate the actual carbon emissions of completed i engineering sub-items ;

[0073] Get the estimated carbon emissions of the i-th project sub-item and all completed project sub-items before the i-th project sub-item , calculated to be Corresponding estimated carbon emissions ;

[0074] according to and Calculate the overall low-carbon construction level of the current construction stage i ;

[0075] The working principle and beneficial effects of the above technical solution are as follows: after each engineering sub-item is actually completed, the actual carbon emissions of the completed engineering sub-item are collected, and combined with the corresponding estimated carbon emissions to calculate the overall low-carbon construction level of the current construction stage. Taking the i-th engineering sub-item as an example, after the i-th engineering sub-item is actually completed, the actual carbon emissions of the i-th engineering sub-item are collected. , and obtain the actual carbon emissions of all completed engineering sub-items before the i-th engineering sub-item , calculate the actual carbon emissions of completed i engineering sub-items , and then obtain the estimated carbon emissions of the i-th project sub-item and all completed project sub-items before the i-th project sub-item , calculated to be Corresponding estimated carbon emissions , finally according to and Calculate the overall low-carbon construction level of the current construction stage i ,in, is the overall low-carbon construction level of the current construction phase i;

[0076] Furthermore, taking the i-th project sub-item as an example, the actual carbon emissions of the i-th project sub-item are collected. , and obtain the estimated carbon emissions corresponding to the i-th project sub-item , calculate the low-carbon construction level of the current construction stage i Through this technical solution, the low-carbon construction level of each construction stage in the construction project and the overall low-carbon construction level of all completed construction stages can be accurately measured, providing reliable data support for achieving energy conservation and carbon reduction throughout the life cycle of the construction stage of the construction project.

[0077] In one embodiment, a method for intelligently controlling carbon emissions during the construction phase of a building project further includes: establishing in advance a carbon emission assessment standard for the construction phase of the building project; wherein the carbon emission assessment standard is used to assess the overall low-carbon construction level, including four-level assessment indicators of excellent, good, qualified, and poor;

[0078] The working principle and beneficial effects of the above technical solution are as follows: in order to better intelligently control carbon emissions during the construction phase of a construction project, the present application also proposes a method for establishing a carbon emission assessment standard for the construction phase of a construction project. The carbon emission assessment standard is used to assess the overall low-carbon construction level (overall carbon reduction rate or stage carbon reduction rate (carbon reduction amount / total estimated construction carbon emissions)). In the present application, the carbon emission assessment standard includes four levels of assessment indicators: excellent, good, passing, and poor. Among them, excellent is preferably greater than 5%, good is preferably 3%-5%, passing is preferably 1%-3%, and poor is preferably less than 1%. By establishing a complete carbon emission assessment standard for the construction phase of a construction project, it is beneficial to improve the overall consistency of the assessment of the carbon emission level during the construction phase of a construction project.

[0079] In one embodiment, if the calculated overall low-carbon construction level is lower than the expected level, the corresponding carbon reduction measures are taken according to the level difference to intelligently adjust the actual carbon emissions of the next project sub-item, including:

[0080] Obtain the expected level selected by the user; the expected level is any one of the four levels of excellent, good, pass and poor;

[0081] After the actual completion of the i-th project sub-item, determine whether the calculated overall low-carbon construction level is lower than the expected level;

[0082] If the result of the judgment is that the calculated overall low-carbon construction level is lower than the expected level, the difference between the overall low-carbon construction level and the expected level is calculated to obtain the level difference; if the expected level is a range of values, the minimum value in the expected level is taken for the level difference calculation;

[0083] Retrieve various carbon reduction measures that can be used for the i+1 project sub-item in the carbon reduction measures library, and obtain the quantified carbon reduction effect of each carbon reduction measure;

[0084] According to the level difference, determine the carbon reduction effect of the i+1 project sub-item demand ;in, Satisfy the first inequality;

[0085] The first inequality is:

[0086]

[0087] in, Indicates the actual carbon emissions of completed engineering sub-items. Representation and The corresponding estimated carbon emissions are Indicates the expected level, represents the estimated carbon emissions of the i+1th project sub-item;

[0088] Carbon reduction effect according to demand Retrieve corresponding measures from various carbon reduction measures of the i+1 project sub-item to intelligently regulate the actual carbon emissions of the i+1 project sub-item;

[0089] The working principle of the above technical solution is as follows: the above technical solution is used to conduct a phased quantitative assessment or an overall quantitative assessment of the low-carbon construction level during the construction phase, by comparing the carbon reduction target (expected level) with the assessment result (overall low-carbon construction level / phased low-carbon construction level), and then selecting various carbon reduction measures in the carbon reduction measures library according to the actual progress of the current project, for carbon reduction regulation of the construction process, and repeatedly adjusting the low-carbon construction level through the above process until the expected target is achieved;

[0090] Specifically, the scheme needs to first obtain the expected level selected by the user, which is any one of the four levels of excellent, good, pass and poor. It is worth noting that the above four-level division is only an embodiment method of the scheme and is not limited to this division rule;

[0091] In order to better illustrate this technical solution, take the i-th engineering sub-item as an example;

[0092] After the actual completion of the i-th project sub-item, it is determined whether the calculated overall low-carbon construction level is lower than the expected level. The determination method is a comparison method, which compares the calculated overall low-carbon construction level corresponding to the i-th project sub-item with the expected level;

[0093] If the overall low-carbon construction level is not lower than the expected level, no action is taken;

[0094] If the overall low-carbon construction level is lower than the expected level, the difference between the overall low-carbon construction level and the expected level is further calculated. For example, if the expected level is good, according to the above records, the good value is (3%-5%), then 3% is used as the expected level value for the difference calculation. Assuming that the overall low-carbon construction level corresponding to the current i-th project sub-item is 2.85%, then the level difference is 0.15% at this time;

[0095] When it is determined that the overall low-carbon construction level corresponding to the current i-th project sub-item is lower than the expected level, it is also necessary to retrieve various carbon reduction measures that can be used for the i+1-th project sub-item in the carbon reduction measures library and obtain the quantified carbon reduction effect of each carbon reduction measure;

[0096] Then, according to the specific value of the above-mentioned level difference, the carbon reduction effect of the i+1 project sub-item requirement is determined. , so that the overall low-carbon construction level corresponding to the i+1th engineering sub-item is not less than 3%; it is worth noting that in the first inequality is the estimated actual carbon emissions of the i+1 project component after the implementation of carbon reduction measures;

[0097] Finally, the carbon reduction effect is based on the demand Retrieve the corresponding measures from the various carbon reduction measures of the i+1 project sub-item to intelligently regulate the actual carbon emissions of the i+1 project sub-item, and after the actual completion of the i+1 project sub-item, calculate whether the overall low-carbon construction level corresponding to the i+1 project sub-item meets the expected level based on the actual carbon emissions, and if it does not meet the expected level, continue to implement the above low-carbon regulation strategy in the i+2 project sub-item, to achieve an active cycle of evaluation-regulation, and exit the cycle after meeting the expected level;

[0098] Furthermore, this solution is also used to evaluate the low-carbon construction level of the project sub-items and compare them with the expected level. The project sub-items that are not in compliance with the comparison results are displayed independently, so that users can check the project sub-items after completion to determine the reasons why they do not meet the expected low-carbon level, and help subsequent construction projects improve the low-carbon construction plan;

[0099] The beneficial effect of the above technical solution is: through the above technical solution, it is used to solve the problem that traditional carbon emission calculation methods cannot actively regulate carbon emissions during the construction phase, which is beneficial to improving the overall carbon emission intelligent management efficiency during the construction phase of the building project.

[0100] In one embodiment, the carbon reduction effect according to the demand Retrieve the corresponding measures from the various carbon reduction measures of the i+1 project sub-item, including:

[0101] Carbon reduction effect according to demand Randomly select corresponding measures from various carbon reduction measures of the i+1th project sub-item; wherein the random selection satisfies the second inequality;

[0102] The second inequality is:

[0103]

[0104] in, is the number of corresponding measures randomly selected, is the estimated carbon emission of the jth sub-project in the randomly selected i+1th project sub-project, is the carbon reduction effect of the jth small project after using corresponding measures;

[0105] The working principle and beneficial effects of the above technical scheme are as follows: This scheme is used to call appropriate carbon reduction measures in the carbon reduction measures library to save energy and reduce carbon emissions for corresponding engineering sub-items. In order to improve the adaptability of calling carbon reduction measures for each engineering sub-item, this scheme adopts a random calling method to allocate carbon reduction measures, which is beneficial to improving the robustness of the system constituted by this method, reducing the calling error caused by human participation, and enhancing the automation capability of intelligent carbon emission management and control; further, in order to improve the adaptability of calling carbon reduction measures to actual conditions, it is preferred to increase weight selection to assist users in adding weights to some carbon reduction measures so that they can be selected with a high probability when randomly selecting small projects.

[0106] In one embodiment, a method for intelligently controlling carbon emissions during the construction phase of a building project further includes:

[0107] If the calculated overall low-carbon construction level is lower than the expected level, continue to determine whether the low-carbon construction level of the current project sub-item is lower than the expected level;

[0108] If the low-carbon construction level of the current engineering sub-item is lower than the expected level, the carbon emission data of all small projects of the current engineering sub-item are acquired to obtain the second actual carbon emission of each small project of the current engineering sub-item;

[0109] Intelligently check each second actual carbon emission to determine whether each second actual carbon emission is higher than a preset normal value range of the corresponding small project, and generate a determination result;

[0110] Acquire small projects with a judgment result that is higher than a preset normal value range as target small projects, judge whether the second actual carbon emission of each target small project is higher than the corresponding preset second normal value range, and generate a second judgment result;

[0111] If the second judgment result is higher than the preset second normal value range, the corresponding target small item is determined to be an abnormal small item and marked and output;

[0112] If the second judgment result is not higher than the preset second normal value range, weighting is assigned to the corresponding target sub-item;

[0113] The working principle and beneficial effects of the above technical solution are as follows: in actual construction projects, the larger the initial carbon emissions, the greater the actual carbon reduction amount for the same carbon reduction quantitative effect when carbon reduction measures are adopted. Based on this, the application also proposes a strategy for assigning weights to small items of each engineering sub-item, thereby increasing the probability of the corresponding carbon reduction measures being selected, thereby improving the carbon reduction efficiency;

[0114] Specifically, first, when the calculated overall low-carbon construction level is lower than the expected level, continue to judge whether the stage low-carbon construction level of the current project sub-item is lower than the expected level. If the stage low-carbon construction level of the current project sub-item is lower than the expected level, obtain carbon emission data for all small projects of the current project sub-item to obtain the second actual carbon emission of each small project of the current project sub-item, and then intelligently check each second actual carbon emission to judge whether each second actual carbon emission is higher than the preset normal value range of the corresponding small project, and generate a judgment result, wherein, higher than the preset normal value range means that the second actual carbon emission is greater than the maximum value in the preset normal value range of the corresponding small project, and the preset normal value range is related to the corresponding small project, and the selection of the small project is determined by the specific construction plan and process of each project sub-item; then obtain the small project whose judgment result is higher than the preset normal value range as the target small project, judge whether the second actual carbon emission of each target small project is higher than the corresponding preset second normal value range, and generate a second judgment result, that is, judge whether the second actual carbon emission is higher than the corresponding preset second normal value range. Far higher than the corresponding preset normal value range, the limited range far higher than is preferably greater than twice the maximum value in the normal value range, or can be expressed as the maximum value of the preset second normal value range is twice the maximum value in the normal value range; finally, if the second judgment result is far higher than the preset normal value range, the corresponding target small project is determined to be an abnormal small project and marked and output, which is used to alert the user and assist the user to rectify the specific construction plan of this part of the small project to prevent carbon emissions from affecting the subsequent construction process; if the second judgment result is not far higher than the preset normal value range, the corresponding target small project is weighted. Since there may be multiple repeated small construction projects during the entire life cycle of engineering construction, the corresponding carbon reduction measures for these repeated small construction projects are the same. Therefore, weights are assigned to the target small projects and associated with the corresponding carbon reduction measures, so that the small projects in the aforementioned second inequality can be automatically selected without user interference, which is beneficial to improving the intelligence level and carbon reduction efficiency of this application.

[0115] In one embodiment, a smart management and control of carbon emissions during the construction phase of a building project further includes:

[0116] Obtain the first leading person of the abnormal small project, and determine whether the current accumulated project abnormality rate of the first leading person exceeds the preset abnormality threshold;

[0117] If the judgment result is that the project abnormality rate exceeds the preset abnormality threshold, all small projects that the first leading person in the subsequent engineering sub-items that have not yet been constructed are responsible for are obtained, and a small project set is obtained;

[0118] Retrieve all idle leading personnel and corresponding historical project leading information in the database, and calculate the first similarity between the historical project leading information corresponding to each leading personnel and the small project set;

[0119] The leading personnel corresponding to the leading information of the historical projects whose first similarity is greater than the preset similarity threshold are obtained as the second leading personnel, and the suitability of each second leading personnel to the current construction project is calculated based on the priority indexes of all the second leading personnel; wherein the priority index is related to the project abnormality rate, and the higher the abnormality rate of the historical projects, the lower the priority index;

[0120] The second leading person with the highest degree of adaptability is selected as the target leading person, and the historical project leading information, similarity information, priority index and adaptability of the target leading person are extracted to generate a recommendation list, which is then fed back to the backend management personnel;

[0121] The working principle of the above technical solution is as follows: in actual construction scenarios, after investigation, it is found that when the second actual carbon emission of the target small project is much higher than the corresponding preset normal value range, it is usually due to the increase in carbon emissions caused by improper operation of the construction personnel. In order to solve this problem and actually reduce carbon emissions, this solution proposes a project leader recommendation method;

[0122] First, when an abnormal small project appears, the first person in charge of the abnormal small project is obtained, and it is determined whether the current accumulated project abnormality rate of the first person in charge exceeds the preset abnormality threshold. The project abnormality rate is the proportion of abnormal small projects in the current led projects to all the led projects; the preset abnormality threshold is defined by the management personnel and is usually set to 20%; if it does not exceed, it is only marked and no other actions are taken;

[0123] If the judgment result is that the project abnormality rate exceeds the preset abnormality threshold, all small projects in the subsequent engineering sub-items that are not yet constructed and are responsible for by the first leading personnel are obtained, and a small project set is obtained. Based on this, all idle leading personnel and corresponding historical project leading information in the database are retrieved, and then the first similarity between the historical project leading information corresponding to each leading personnel and the small project set is calculated; wherein the calculation method of the first similarity is preferably:

[0124]

[0125] Among them, XSD is the first similarity, A is the small project set, and B is the project set in the historical project leading information corresponding to any leading person;

[0126] The leading personnel corresponding to the historical project leading information whose first similarity is greater than the preset similarity threshold are obtained as the second leading personnel, and the suitability of each second leading personnel to the current construction project is calculated based on the priority index of all the second leading personnel; the suitability calculation method is preferably:

[0127]

[0128] in, The suitability of any second lead person for this construction project, is the priority index of the corresponding second leading person, ,in, is a constant, is the historical project abnormality rate of the corresponding second leading personnel, is the number of small items in the small item set, is the historical number of times the second leading person has dominated the first small project in the small project set, The average number of times all second leaders dominate the first small project in the small project set;

[0129] Finally, the second leading person with the highest degree of adaptability is selected as the target leading person, and the historical project leading information, similarity information, priority index and adaptability of the target leading person are extracted to generate a recommendation list, which is then fed back to the backend management personnel;

[0130] Through the above scheme, the leading personnel who seriously affect the carbon reduction efficiency of the current construction project are marked, and the most suitable candidate project leaders are screened based on the remaining projects to recommend to the back-end management personnel, which is used to solve the problem of excessive carbon emissions caused by improper human operation, which is beneficial to increase the actual carbon reduction of the project, and further adopt the method of replacing personnel to actively regulate carbon emissions during the construction phase.

[0131] like Figure 2 As shown, in one embodiment, a carbon emission intelligent management and control system for a construction project during the construction phase includes:

[0132] The carbon emission estimation module for the construction phase of a building project is used to divide the project into multiple sub-projects according to the estimated construction progress and construction plan of the building project; and to estimate the carbon emissions of each sub-project based on the traditional construction plan and process to obtain multiple estimated carbon emissions;

[0133] The carbon emission measurement module for the construction phase of a building project is used to collect the actual carbon emissions of each completed project item after it is actually completed;

[0134] The carbon reduction library module for the construction phase of a building project is used to establish a library of carbon reduction measures applicable to various stages of various types of construction projects;

[0135] The real-time carbon emission assessment module for the construction phase of a building project is used to calculate the overall low-carbon construction level of the current construction phase by combining the actual carbon emissions with the corresponding estimated carbon emissions, and to conduct a real-time assessment of the overall low-carbon construction level based on the expected level;

[0136] The carbon emission control module during the construction phase of a building project is used to intelligently control the actual carbon emissions of the next project item by taking corresponding carbon reduction measures based on the level difference when the overall low-carbon construction level is lower than the expected level.

[0137] The working principle and beneficial effects of the above technical solution have been explained in the method claims and will not be repeated here.

[0138] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
