Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon emission accounting, and particularly relates to a carbon emission accounting method for a high-speed rail passenger station. BACKGROUND

[0002] With the increasing global concern about climate change, reducing carbon emissions has become one of the important goals for solving the current climate problem. Since the life cycle of a building includes the construction period, the operation period, and the demolition period, the carbon emission amount in the operation period accounts for a large proportion of the total carbon emission amount in the overall life cycle. Under this background, it is particularly important to scientifically and accurately monitor the carbon emission amount of various buildings in the operation period, so as to provide data support for formulating and implementing effective energy-saving and emission-reducing measures, thereby effectively promoting the mitigation process of climate problems.

[0003] The current carbon emission accounting of a building can be performed by the following method: 1. Obtain basic information of each stage in a building scheme and basic information of vegetation in each stage in a building area, calculate carbon emission amounts of each stage according to the basic information of each stage, respectively, calculate carbon reduction amounts of each stage according to the basic information and the basic information of vegetation of each stage, and then calculate a total carbon emission amount of the building scheme according to the carbon emission amounts and the carbon reduction amounts of each stage. The stages of the building scheme include a building material production stage, a building material transportation stage, a construction stage, an operation stage, and a demolition stage. The calculation of the carbon emission amount of the operation stage includes the following steps: after receiving parameters of a heating, ventilation, and air conditioning (HVAC) system, environmental parameters of the HVAC system, a global warming potential of a refrigerant, and a consumption amount of the refrigerant, calculate a first carbon emission amount of the HVAC system by using a monthly average algorithm according to the parameters of the HVAC system and the environmental parameters of the HVAC system, calculate a second carbon emission amount of the HVAC system according to the global warming potential of the refrigerant and the consumption amount of the refrigerant, and calculate a carbon emission amount of the HVAC system according to the first carbon emission amount and the second carbon emission amount of the HVAC system; after receiving an electricity consumption amount and an energy consumption amount of a domestic hot water system, calculate a carbon emission amount of the domestic hot water system; after receiving an electricity consumption amount of a lighting system, calculate a carbon emission amount of the lighting system; after receiving an electricity consumption amount of an elevator system, calculate a carbon emission amount of the elevator system; and after receiving an energy amount (including electric energy and thermal energy) generated by a power generation amount of a renewable energy system, calculate a carbon reduction amount of the renewable energy system. Thus, the total carbon emission amount of the operation stage of the building can be determined according to the carbon emission amounts and the carbon reduction amounts.

[0004] 2. Calculate the carbon emission of the public building in the construction process according to the carbon emission of the building material production process of the public building, the building area of the public building and the building floor of the public building; calculate the carbon emission of the public building in the operation process according to the carbon emission of the total fuel consumption of the public building in the operation stage and the building area of the public building; calculate the carbon emission of the public building in the demolition process according to the building floor of the public building; calculate the sum of the carbon emissions of the public building in the construction process, the operation process and the demolition process to obtain the life cycle carbon emission of the public building. When calculating the carbon emission in the operation process, the carbon emission of each unit weight of fuel in the operation stage of the public building, the total consumption of each fuel in the public building and the building area of the public building are calculated.

[0005] However, as a large energy consumer in the construction industry, the unit area energy consumption index of the high-speed railway station is much higher than that of the conventional public building. If the above schemes are used to calculate the carbon emission, since the above two schemes do not cover all necessary indicators in the high-speed railway station scenario when calculating the total carbon emission of the building in the operation stage, for example, the second scheme does not involve the carbon emission generated when supplying hot water, and the first scheme involves the carbon emission of the hot water system, but does not fully consider the carbon emission factors of hot water supply.

[0006] Therefore, it is impossible to accurately calculate the carbon emission of the high-speed railway station by using the current building carbon emission calculation scheme. SUMMARY

[0047] Based on this, the coal use direct carbon emission amount can be calculated by combining the data in the carbon emission source list in the following way: C1=U coal ×h1× ×r1; Among them, C1 is the coal use direct carbon emission amount, U coal is the annual use amount of coal, h1 is the calorific value, is the emission factor of carbon dioxide per unit calorific value, and r1 is the carbon oxidation rate.

[0048] And the liquefied petroleum gas use direct carbon emission amount can be calculated by combining the data in the carbon emission source list in the following way: C2=U lpg ×h2× ×r2; Among them, C2 is the liquefied petroleum gas use direct carbon emission amount, U lpg is the annual use amount of liquefied petroleum gas, h2 is the calorific value, is the emission factor of carbon dioxide per unit calorific value, and r2 is the carbon oxidation rate.

[0049] And, the direct carbon emission of natural gas use is calculated by combining the data in the carbon emission source list in the following way: C3=U n ×h3× ×r3; Wherein, C3 is the direct carbon emission of natural gas use, U n is the annual use amount of natural gas, h3 is the calorific value, is the emission factor of carbon dioxide per unit calorific value, and r3 is the corresponding carbon oxidation rate.
