With the continuous expansion of building scale and the increasing number of energy-consuming equipment and facilities in buildings, the demand for building energy conservation is increasing day by day. Among the many building energy-saving technologies, the building energy consumption supervision platform has been widely supported and promoted in recent years because it can realize real-time monitoring and management of building (group) energy consumption, thereby effectively reducing building energy consumption and improving management level.

[0003] Building carbon reduction has become the development trend of building energy consumption supervision platform technology. However, in the process of transforming the platform into building energy carbon supervision, its building carbon emission function technology is not mature, and the main deficiencies are as follows:

[0004] 1. In the existing smart building supervision platform, energy management is relatively mature, but carbon emission management is relatively lacking;

[0005] 2. The carbon emission calculation of existing platforms usually adopts fixed carbon emission factors, which lacks dynamic adjustment in terms of region and time;

[0006] 3. The carbon emission calculation method in the existing platform lacks modular design, making it difficult to flexibly adjust and optimize, and various influencing factors have not been fully and independently considered and analyzed;

[0007] 4. The carbon emission management module of the existing platform has single functions and limited functions, poor compatibility between systems, and a lack of planning for the dual carbon process. The existing carbon emission analysis results are difficult to fully apply to actual decision-making and optimization processes. Summary of the invention

[0008] The present invention proposes a carbon emission management system suitable for a building energy carbon supervision platform, which integrates the calculation statistics, analysis and evaluation, and planning and expectation processes of building carbon emissions to form a complete building carbon emission management system.

[0009] The technical solution adopted by the present invention to solve its technical problems is: a carbon emission management system for a building energy carbon supervision platform, including: a carbon emission statistics module, a carbon emission calculation and evaluation module and a carbon planning module, the carbon emission statistics module includes: a carbon emission factor management submodule, a real-time data submodule, a historical data submodule and a system data submodule, the carbon emission factor management submodule is used for defining and managing carbon emission factors, the real-time data submodule calculates the carbon emission data of the building in real time according to the energy consumption monitoring situation, the historical data submodule is used to store the carbon emission data of each time period, the system data submodule is used to classify and manage the specific data of different energy consumption systems, and also It can provide basic data for carbon emission statistics and analysis. The carbon emission calculation and evaluation module includes: a carbon emission calculation submodule and a carbon emission reduction benefit analysis submodule.

The dual-carbon process analysis submodule calculates and displays the building carbon emission expectations based on the carbon neutrality calculation results and the building operation and maintenance plan.

[0010] Therefore, through the carbon planning module, the calculation statistics, analysis and evaluation, and planning and expectation processes of building carbon emissions can be connected to form a complete building carbon emission management system. On the basis of the basic data and functions of the energy carbon supervision platform, according to the actual project needs, it provides users with comprehensive and clear carbon emission management services; through the carbon emission factor management sub-module, it can take into account the significant differences in carbon emission factors in different regions and time periods, introduce dynamically adjusted carbon emission factors, and according to the requirements of different projects, through real-time acquisition and updating of regional electricity carbon emission factors, energy structure changes and other data, so that carbon emission calculations can accurately reflect the actual situation and avoid calculation errors caused by fixed factors.

[0011] Furthermore, the carbon emission calculation submodule needs to set a benchmark carbon emissions under the same conditions; among which: the renovated building will use the carbon emissions of the building one year before the renovation as the benchmark; the benchmark for the newly built building will be set according to the "Public Building Energy Saving Design Standard" GB50189-2015 or the "General Specification for Building Energy Saving and Renewable Energy Utilization" GB55015-2021 based on specific project requirements.

[0026] Furthermore, the net carbon emissions of buildings are c , n The calculation formula is:

[0027] E c.n =E c.a -E c.s -E c.o -E c.p ;

[0028] Where: E c.s Indicates the amount of carbon emissions reduced by carbon sinks, in teCO2, E c.o Indicates the carbon emissions offset by carbon credits, in teCO2, E c.p Represents the carbon emissions offset by green electricity purchases, in teCO2.

[0029] Furthermore, the building carbon emission trend starts from the year when the building is put into use and has complete annual carbon emission records.

[0031] Furthermore, based on the record starting year data provided by the user, the expected calculation model of building carbon emissions based on building system efficiency is used to calculate the carbon emissions in the ath year C a The calculation formula is:

[0032]

[0033] Where: c i.arepresents the carbon emission factor of the i-th energy form in year a, α represents the energy density, which changes mainly according to the number of building users and their behavioral characteristics, and E d.i represents the benchmark energy consumption of the i-th energy-consuming system, in kWh, R ed.i It represents the efficiency ratio of the energy-using system in year a to the base year, E p.i represents the base annual energy consumption of the i-th energy generation system, in kWh, R ep.i represents the efficiency ratio of the capacity system in year a to the base year, C o.i It represents the carbon reduction of the i-th carbon offset method, in teCO2; the expected value of original net emissions takes into account system equipment aging and equipment replacement.

[0051] In this embodiment, the carbon emission calculation submodule needs to set the benchmark carbon emissions under the same conditions; among them: the renovated building will use the carbon emissions of the building one year before the renovation as the benchmark; the benchmark for the newly built building will be set according to the "Public Building Energy Saving Design Standard" GB50189-2015 or the "General Specification for Building Energy Saving and Renewable Energy Utilization" GB55015-2021 based on the specific project requirements.

[0052] In this embodiment, in the carbon emission reduction benefit analysis, the total investment cost I t The calculation formula is:

[0053] I t =I i +∑I m ;

[0054] Where: I i represents the initial investment cost, I m represents the annual maintenance cost;

[0058]

[0059] Total income B t The calculation formula is:

[0060] B t =∑B e +∑B C ;

[0064] E c.a =E c.b -E c.d -E c.g -E c.f ;

[0065] Where: E c.b Indicates the baseline carbon emissions in teCO2, E c.d Indicates the amount of carbon removed by the building itself, in teCO2, E c.g Indicates the amount of carbon emissions reduced by using renewable energy production capacity, in teCO2, E c.f It indicates the amount of carbon emissions reduced due to the reduction of carbon emission factor, in teCO2;

[0066] Net carbon emissions of buildings c , n The calculation formula is:

[0067] E c.n =E c.a -E c.s -E c.o -E c.p ;

[0068] Where: E c.sIndicates the amount of carbon emissions reduced by carbon sinks, in teCO2, E c.o Indicates the carbon emissions offset by carbon credits, in teCO2, E c.p Indicates the carbon emissions offset by green electricity purchases, in teCO2. Thus, through multiple independent modules (including but not limited to BAU (Business as Usual), power factor reduction, energy use reduction, green energy, actual emissions, carbon sinks, carbon credit offsets, and green electricity purchases), each module independently calculates its impact on carbon emissions. The modular design not only improves the flexibility and accuracy of the calculation, but also facilitates the individual optimization and adjustment of each module to achieve further carbon reduction analysis and benefit analysis; the waterfall chart display method can intuitively display the carbon reduction effect of each module, which is convenient for understanding and further decision-making.

[0070] Specifically, the carbon emission-related data of previous years are based on time monitoring results, while the data of the current year are determined based on the customer's actual planning strategy and calculation and prediction results.

[0071] In this embodiment, the building carbon emission trend takes the year with complete annual carbon emission records after the building is put into use as the starting point, and the building carbon emission trend includes: actual net emission trend curve, actual net emission expected curve, and original net emission expected curve; the actual net emission trend curve represents the actual recorded annual net carbon emissions of the building; the actual net emission expected curve takes into account the building renovation and carbon offset investment plan; the original net emission expected curve takes the first year of carbon emission record as the starting point, and does not take into account the renovation investment of carbon reduction measures; based on the record starting year data provided by the user, the building carbon emission expected calculation model based on the building system efficiency, the carbon emissions C in the ath year a The calculation formula is:

[0074] Specifically, the energy density α can be simplified as the building occupancy rate.

[0075] For example, the change of carbon emission factor of electricity is calculated according to the method of "Research on Carbon Dioxide Emission Factor of Regional Power Grid in China"; the energy consumption system takes into account the air conditioning system, lighting system, power system, and the influence of the insulation system is converted into the air conditioning system; the energy production system takes into account the photovoltaic system, solar water heating system, wind power generation system, and heat recovery system. ep.i Numerical setting principles and R ed.i The principles for setting values ​​are the same; carbon offset methods include carbon sinks, carbon credits, and the use of green electricity, and the expected value of original net emissions does not take this into account in the calculation.

[0076] In summary, the present invention can connect the calculation statistics, analysis and evaluation, and planning and expectation processes of building carbon emissions to form a complete building carbon emission management system.
