[0039] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0040] The embodiment of the present invention provides a method for calculating carbon emissions from building construction, referring to Figure 1 , Figure 1 It is a flow chart of a first embodiment of a method for calculating carbon emissions from building construction according to the present invention.

[0041] In this embodiment, the method for calculating the carbon emissions from building construction includes the following steps:

[0042] Step S10: Determine the construction stage of the building.

[0043] In this embodiment, the executor of this embodiment is a building construction carbon emissions calculation device, wherein the building construction carbon emissions calculation device has functions such as data processing, data communication and program running. The building construction carbon emissions calculation device can be a computer terminal device or other network device, and of course it can also be other devices with similar functions, and this embodiment does not limit this.

[0044] It should be noted that the calculation of carbon emissions from building construction is an important data basis for controlling carbon emissions at different stages of construction projects. It is not only an important guiding document for the formulation of carbon reduction measures for projects, but also an important basis for carbon certification, carbon trading and carbon management of construction projects. Therefore, rapid estimation of carbon emissions from construction projects is crucial for carbon management of construction projects. The current method of calculating carbon emissions from building construction is to multiply the building area by the empirical carbon emission coefficient to get a very rough value, or to manually calculate energy and material carbon emissions during the construction process. However, this method has a large statistical workload, insufficient type integrity, low numerical accuracy, and a large time span, which affects the accurate decision-making on carbon management of construction projects.

[0045] In order to solve this technical problem, this embodiment determines the construction stage of the building; obtains each sub-item quantity based on the construction stage, and the sub-item quantities include electricity consumption, gasoline consumption, diesel consumption, steel consumption, concrete consumption, mortar consumption, block consumption and prefabricated component consumption; determines each sub-item quantity based on the sub-item quantity and construction quota according to the relationship; determines each sub-item carbon emission according to the sub-item quantity; determines the carbon emissions corresponding to the construction stage according to the carbon emissions of each sub-item and the proportion of carbon emissions of other materials. The carbon emissions of the building construction can be quickly calculated for different stages of construction. It has the advantages of fast calculation speed, simple operation, wide applicability, etc., can realize the early control of the carbon emissions of the project construction, and ensure the accurate decision-making of carbon management of the construction project. Specifically, it can be achieved as follows.

[0046] In a specific implementation, in this embodiment, carbon emissions can be calculated for different construction stages. Therefore, before calculation, in this embodiment, it is necessary to first determine the construction stage, such as the construction budget stage, the process settlement stage, and the completion settlement stage.

[0047] Step S20: Obtaining the quantities of each sub-item of work based on the construction stage.

[0048] In this embodiment, each sub-item includes electricity, gasoline, diesel, steel bars, concrete, mortar, block usage and prefabricated components. The engineering quantities of each sub-item are different in different stages.

[0049] Step S30: Determine the amount of each sub-item based on the relationship and the construction quota.

[0050] Step S40: determining the carbon emission of each sub-item according to the usage of each sub-item.

[0051] After obtaining the quantities of each sub-item, in this embodiment, the quantities of each sub-item can be determined according to the relationship based on the quantities of each sub-item and the construction quota. The quantities of each sub-item in this embodiment include electricity consumption, gasoline consumption, diesel consumption, steel consumption, concrete consumption, mortar consumption, block consumption and prefabricated component consumption.

[0052] It should be noted that construction quotas are determined by the provincial consumption quotas for different building types in each region or the enterprise-level consumption quotas for different building types.

[0053] Furthermore, after determining the amount of each sub-item, the carbon emission of each sub-item can be further determined in combination with the carbon emission factor. The specific calculation process is to obtain the carbon emission factor corresponding to each sub-item; determine the carbon emission of each sub-item according to the amount of each sub-item and the carbon emission factor corresponding to each sub-item. For example, for the construction budget stage, according to the construction drawing budget engineering quantity, determine the amount of each sub-item as qt1, qt2, qt3...qtn. Use the relationship between construction quotas and sub-item engineering quantities and electricity consumption Determine the electricity consumption d. Multiply the electricity carbon emission factor cD by the electricity consumption d*cD to determine the budgeted engineering quantity electricity carbon emission D. Use the relationship between construction quotas and sub-item engineering quantities and gasoline consumption Determine the gasoline consumption q. Multiply the gasoline carbon emission factor cQ by the gasoline consumption q*cQ to determine the gasoline carbon emission Q of the budgeted project. Use the relationship between construction quotas and sub-item quantities and diesel consumption Determine the diesel consumption c. Multiply the diesel carbon emission factor cC by the diesel consumption c*cC to determine the diesel carbon emission C of the budgeted project. Use the relationship between the construction quota and the sub-project quantity and the steel consumption Determine the amount of steel j. Multiply the steel carbon emission factor cJ by the amount of steel j*cJ to determine the budgeted engineering quantity steel carbon emission J. Use the relationship between construction quotas and sub-item engineering quantities and concrete consumption Determine the amount of concrete h. Multiply the concrete carbon emission factor cH by the concrete amount h*cH to determine the budgeted project concrete carbon emission H. Use the relationship between construction quotas and sub-item project quantities and mortar consumption Determine the mortar consumption s. Multiply the mortar carbon emission factor cS by the mortar consumption s*cS to determine the budgeted mortar carbon emission S. Use the relationship between construction quotas and sub-item quantities and block consumption Determine the amount of blocks k. Multiply the carbon emission factor cK of blocks by the amount of blocks k*cK to determine the carbon emission K of the budgeted project. Use the relationship between construction quotas and sub-item project quantities and prefabricated component quantities Determine the amount of prefabricated components g. Multiply the carbon emission factor cG of prefabricated components by the amount of prefabricated components g*cG to determine the carbon emission amount G of prefabricated components in the budgeted project.

[0054] Step S50: determining the carbon emissions corresponding to the construction phase according to the carbon emissions of each sub-item and the proportion of carbon emissions of other materials.

[0055] After obtaining the carbon emissions of each sub-item, in this embodiment, it is also necessary to combine the carbon emissions of other materials. Specifically, for example, in the building construction budget stage, the carbon emissions of other materials are calculated by four operations: the carbon emissions of the budgeted project volume excluding other materials D+Q+C+J+H+S+K+G to determine the carbon emissions of the building construction budget stage. D1+Q1+C1+J1+H1+S1+K1+G1 is the first cumulative carbon emissions corresponding to the construction budget stage.

[0056] When calculating the carbon emissions of the process settlement, the quantities of each sub-item are determined as qg1, qg2, qg3…qgn according to the process settlement engineering quantity. The relationship between the construction quota and the sub-item engineering quantity and the amount of electricity, gasoline, diesel, steel, concrete, mortar, and masonry blocks is used, and further multiplied by the corresponding carbon emission factor to determine the carbon emissions of electricity, gasoline, diesel, steel, concrete, mortar, and masonry blocks. The carbon emissions of other materials are calculated using the proportion of carbon emissions e to determine the carbon emissions of the construction process settlement stage:

[0057] Among them, D2+Q2+C2+J2+H2+S2+K2+G2 is the second accumulated carbon emissions corresponding to the process settlement stage.

[0058] When calculating the carbon emissions of the completed settlement, the quantities of each sub-item are determined as qw1, qw2, qw3…qwn according to the completed settlement project quantity. The construction quota and sub-item project quantity are used in the relationship between electricity, gasoline, diesel, steel, concrete, mortar, and block consumption, and further multiplied by the corresponding carbon emission factor to determine the carbon emissions of electricity, gasoline, diesel, steel, concrete, mortar, and blocks. The carbon emissions of other materials are calculated using the proportion of carbon emissions e to determine the carbon emissions of the completed settlement stage of the building construction: D3+Q3+C3+J3+H3+S3+K3+G3 is the third accumulated carbon emissions corresponding to the completion settlement stage.

[0059] This embodiment determines the construction stage of the building; obtains each sub-item quantity based on the construction stage; determines each sub-item usage based on the sub-item quantity and the construction quota according to the relationship, and the sub-item usage includes electricity usage, gasoline usage, diesel usage, steel usage, concrete usage, mortar usage, block usage and prefabricated component usage; determines each sub-item carbon emission according to the sub-item usage; determines the carbon emission corresponding to the construction stage according to the carbon emission of each sub-item and the proportion of carbon emission of other materials. The carbon emission of the building construction can be quickly calculated for different stages of construction. It has the advantages of fast calculation speed, simple operation, wide applicability, etc., can realize the early control of the carbon emission of the project construction, and ensure the accurate decision-making of carbon management of the construction project.

[0060] In addition, an embodiment of the present invention further proposes a storage medium, on which a building construction carbon emissions calculation program is stored. When the building construction carbon emissions calculation program is executed by a processor, the steps of the building construction carbon emissions calculation method described above are implemented.
