Under the national dual-carbon background, importance is attached to the carbon emission of a building, and the construction of a low-carbon building is an essential way for realizing the overall target of dual-carbon, but in the building construction process, how to monitor the carbon emission track of building construction materials and reasonably analyze the carbon emission is a problem to be solved at present.
Embodiments of the application are described in further detail below with reference to the drawings.
The embodiment of the application provides a carbon emission analysis method, and the main flow of the method is described as follows.
As shown in fig. 1:
step S101: and obtaining the carbon emission factor of the construction material.
Specifically, the above construction materials represent materials used in the construction process. It can be understood that the carbon emission factor of the construction material can be obtained by analyzing the raw materials, processing energy consumption, processing loss, transportation mode, transportation distance and the like of the construction material in the construction engineering according to the specifications GB/T51366-2019 "building carbon emission calculation Standard" and CECS3742014 "building carbon emission measurement Standard". The analysis of the processing energy consumption and the transportation mode specifically further comprises the analysis of information such as energy types and equipment models used for processing the raw materials. The analysis and calculation method of the carbon emission factor is known to those skilled in the art, and will not be described herein. For example, tap water has a carbon emission factor of 0.168kg CO2e/t, clay has a carbon emission factor of 0.5kg CO2e/t, sand has a carbon emission factor of 6.6kg CO2e/t, crushed stone has a carbon emission factor of 4.4kg CO2e/t, recycled aggregate has a carbon emission factor of 13.0kg CO2e/t, limestone has a carbon emission factor of 430kgCO e/t, dolomite has a carbon emission factor of 474kgCO e/t, fly ash has a carbon emission factor of 8.0kg CO2e/t, slag has a carbon emission factor of 109kgCO e/t, expanded perlite has a carbon emission factor of 2880kgCO e/t, white powder has a carbon emission factor of 175kgCO e/t, talc has a carbon emission factor of 175kgCO e/t, and putty powder has a carbon emission factor of 440kgCO e/t.
Step S102: and determining the actual carbon emission according to the carbon emission factor of the construction material and the actual construction data.
Specifically, the actual construction data represents the actual amount of the construction material used in the construction process. It will be appreciated that the carbon emission factor of each construction material represents the amount of carbon emissions generated by the unit energy of each construction material during use. Therefore, on the premise that the actual amount of the construction material, that is, the actual construction data and the carbon emission factor, is known, the actual carbon emission amount generated by all the construction materials used can be calculated. In a specific embodiment, the carbon emission amount of each construction material may be obtained directly by multiplying the actual amount of each construction material by the carbon emission factor, and then adding the carbon emission amounts of each construction material to obtain the actual carbon emission amount, which represents the carbon emission amount generated at the construction site in one construction cycle. The construction period is determined according to actual requirements and can be one hour, one day, one week and the like.
Because the unit of the usage amount of different construction materials is different, in the actual calculation process, the unit conversion of the actual usage amount of the construction materials is also needed. In this case, the calculation steps are many, and calculation errors are likely to occur. Therefore, in another specific embodiment, a construction scene is built by using a building information model (building information modeling, BIM), and a carbon emission factor is assigned to the BIM, so that the BIM can calculate the actual carbon emission according to the actual construction data.
BIM can help to realize integration of building information, and various information is always integrated in a three-dimensional model information database from design, construction and operation of a building to the end of the whole life cycle of the building. The information database contains not only geometric information, professional attributes and status information describing building elements, but also status information of non-element objects (e.g. space, movement behavior). The database of BIM is dynamically changing, continually updated, enriched and enriched during the application process.
Step S103: and comparing the actual carbon emission amount with the theoretical carbon emission amount to obtain a carbon emission analysis result.
Specifically, the theoretical carbon emission amount is obtained by evaluating the theoretical amount of the construction material in the construction plan. Calculating a deviation rate based on the actual carbon emission amount and the theoretical carbon emission amount; when the deviation rate exceeds a preset deviation range, the carbon emission analysis result is that the carbon emission is excessive.
In a specific embodiment, the deviation ratio is a ratio of a difference between the actual carbon emission amount and the theoretical carbon emission amount to the theoretical carbon emission amount, for example, deviation ratio= (actual carbon emission amount-theoretical carbon emission amount)/theoretical carbon emission amount. When the deviation ratio exceeds a preset deviation range, it means that the difference between the actual carbon emission amount and the theoretical carbon emission amount is large. May be caused by the input error of the actual usage amount of the construction material, or may be caused by the larger loss of the construction material in the actual construction process, it is also possible that the theoretical amount of the construction material and the actual amount differ more due to the fact that the construction plan is adjusted. Because of the situation caused by data errors, the actual carbon emission exceeds standard in other situations, the consumption and the use of construction materials are required to be adjusted according to the carbon emission, unnecessary loss is reduced, and meanwhile, the actual carbon emission is reduced.
For example, according to the uploading data of each time node, the accumulated actual carbon emission and theoretical carbon emission of the construction material are calculated, so that the control effect of the deviation condition can be conveniently observed. When the actual carbon emission exceeds 5% of the theoretical emission, namely the deviation rate is 5%, an early warning signal is output to prompt certain construction materials to take measures to control the loss, and the carbon emission in the construction material processing or installation process is reduced.
It will be appreciated that for engineering projects, a corresponding construction plan is formulated, which includes the construction schedule and the theoretical amount of construction material used corresponding to the construction schedule. The theoretical carbon emission is obtained by: determining a theoretical carbon emission factor of the construction material according to a processed carbon emission factor of the construction material, a transported carbon emission factor, a used carbon emission factor and a theoretical loss rate of the construction material, wherein the processed carbon emission factor is used for reflecting the carbon emission condition in the process of producing the construction material, the transported carbon emission factor is used for reflecting the carbon emission condition in the process of transporting the construction material, and the used carbon emission factor is used for reflecting the carbon emission condition in the process of using the construction material. And determining the theoretical carbon emission according to a building information model and the theoretical carbon emission factor, wherein the building information model comprises a using plan of the construction material.
Further, the above-mentioned processed carbon emission factor is obtained by:
The method comprises the steps of obtaining a processing energy of the construction material, a raw material of the construction material and a processing loss rate, wherein the processing energy represents an energy used in a process of processing the raw material into the construction material, and the processing loss rate represents a loss rate generated in the process of processing the raw material into the construction material. And obtaining the intermediate carbon emission factor according to the carbon emission factor of the raw materials and the processing loss rate. And obtaining the processed carbon emission factor according to the intermediate carbon emission factor and the carbon emission factor of the processed energy.
Further, the above transport carbon emission factor is obtained by:
And obtaining a transportation mode and a transportation distance of the construction material, wherein the transportation distance represents a distance from a production place to a construction place. And obtaining the transportation carbon emission factor according to the transportation mode carbon emission factor, the transportation distance and the transportation loss rate, wherein the transportation loss rate is used for reflecting the loss of the construction material from the production place to the construction place.
In a specific example, the theoretical carbon emission factor is calculated for a certain construction material, with the following formula: c= (1+δ) (C1+C2+ C3) a step of;

In particular, the method comprises the steps of,Wherein C n represents a carbon emission factor of an energy source used in the process from raw material processing to the above construction material, for example, when the energy source is electric power, the unit is kgCO e/(kw·h), and when the energy source is fuel, the unit is kgCO e/t. T gc represents annual energy consumption (electric power unit is kW.h, and fuel unit is ton) of a factory for processing the construction material. Q gc represents the engineering quantity of the construction material produced by the factory in terms of ton. C yc represents the carbon emission factor of the above raw materials, and the unit is kgCO e/t. Alpha represents the theoretical material loss rate of the raw material processed into the construction material.
In particular, the method comprises the steps of, c2=c ys ×l (1+β); wherein C ys represents a carbon emission factor of a transportation mode selected from a production place to a construction place, and the unit is kgCO e/(t.km). L represents a transport distance in meters from the production site to the construction site. Beta represents the theoretical material loss rate generated in the process of transporting the construction material from the production place to the construction place.
