By calculating the carbon emission value of a building, it is possible to better identify and quantify its impact on climate change, and at the same time help formulate corresponding energy conservation and emission reduction strategies to further respond to the "dual carbon" policy.

[0003] The calculation of carbon emissions during the building operation stage is an extremely important part of building energy conservation and carbon reduction. However, there are still the following problems in the current field of building carbon emission calculation:

[0004] 1. In the early stage of building carbon emission calculation, the formula calculation part lacks data support. Real data and calculation data cannot be matched, data fragmentation is obvious and the collection difficulty is large, which affects the promotion efficiency of carbon emission calculation work;

[0005] 2. From a concrete perspective, the current building carbon emission calculation method does not take into account the numerical difference effects brought by the building location and different building types on carbon emission calculation;

[0012] S2: Perform consistency processing on the acquired data. Adopt the uncertainty measurement algorithm to conduct quality assessment and screening on various types of data, and select the data with the highest credibility as the final result. For the inconsistency between each data functional unit and the calculation boundary collected from the channels described in step S1, adopt the uncertainty measurement algorithm to process the independent variable values of different data sources, calculate the overall uncertainty corresponding to each independent variable, and select the value with the lowest uncertainty and the highest credibility as the final data result of this independent variable.

[0013] S3: Based on the processed data information, construct a standardized database required for carbon emission calculation, and perform hierarchical coding on the data according to building characteristics and system characteristics and establish data links.

Database preparation steps before calculation: Clarify the basic information of the target building, and sequentially select and match the data encoded at each level to ensure that the value of each independent variable corresponds to the characteristics of the target building.

[0015] S5: Use the matched data, combined with the calculation formulas and simulation tools of various building energy consumption systems, to calculate the energy consumption of various systems during the operation of the building. Energy consumption calculation steps: According to the results obtained from database processing, use simulation software to calculate the energy consumption of the air conditioning system, and calculate the energy consumption of other systems (such as domestic hot water, lighting, elevators) through the energy consumption calculation formulas provided in the "Standard for Building Carbon Emission Calculation".

[0016] S6: Based on the building energy consumption results, substitute them into the carbon emission calculation formula to complete the calculation of the total carbon emission during the operation stage of the target building. Building carbon emission calculation steps: Substitute the energy consumption values of various systems obtained in step e) into the building operation stage carbon emission calculation formula in the "Standard for Building Carbon Emission Calculation" to finally calculate the carbon emissions of the target building.

When calculating the total carbon emission per unit building area in the building operation stage (C M ), it should be calculated according to the following formula: Among them, C M is the carbon emission per unit building area in the building operation stage (kg / CO2); E i is the annual consumption of the i-th type of energy in the building (unit / S1; EF i is the carbon emission factor of the i-th type of energy, which is taken according to Appendix A of this standard; E i,j is the consumption of the i-th type of energy of the j-th system (unit / S1; ER i,j is the amount of the i-th type of energy consumed by the j-th system provided by the renewable energy system (unit / S1; i is the type of terminal energy consumed by the building, including electricity, gas, oil, municipal heating, etc.; h is the type of building energy consumption system, including heating, air conditioning, lighting, domestic hot water system, etc.; C p is the annual carbon reduction amount of the building green space carbon sink system (kgCO2 / S1; y is the building design life (S1; A is the building area (m2).
