[0034] Figure 2 This is a schematic diagram of the structure of a building carbon emission operation benefit calculation system in one embodiment of the present disclosure;

[0035] Figure 3 This is a data display interface of a building carbon emission operation benefit calculation system in one embodiment of the present disclosure. DETAILED DESCRIPTION

[0036] In order to facilitate the understanding of the present disclosure, the present disclosure is described in more detail below with reference to the accompanying drawings and specific embodiments.

[0037] Please refer to Figure 1 The embodiment of the present disclosure proposes a method for calculating the carbon emission operation benefit of a building, including:

[0038] Step 1: Clarify the scope of building carbon emission operation benefit calculation.

[0039] Step 2: Collect basic information on building carbon emissions and operating benefits.

[0040] Step 3: Establish a carbon emission operation benefit calculation model for renewable energy utilization:

[0041]

[0042] Among them, B k To establish the carbon emission operating benefits of renewable energy utilization, the unit is RMB; ER i,j Carbon reduction generated by the use of renewable energy systems in buildings, in kgCO2 / a; P c is the carbon emission price of the city where the building is located in that year, in yuan / tCO2; i,j EF is the total amount of energy of type i generated by the renewable energy system of type j; i is the carbon emission factor of the i-th energy type.

[0043] Specifically, for example, the carbon emission price in Shenzhen, where the building is located, is 55 yuan / tCO2 that year; the carbon emission factor of electricity is 0.581kgCO2 / kWh. Based on the annual power generation of an office building in Shenzhen of 2.88 million kWh, B k =2880000h×0.581 / 1000×55=92030.4 yuan.

[0044] Step 4: Establish a carbon emission operation benefit calculation model for the building green space carbon sink system:

[0045]

[0046] Among them, B C is the carbon emission operation benefit of the building green space carbon sink system, in yuan; C p,i is the CO2 fixation per unit green area of ​​type i planting method, in kg / m 2 , A l,i is the green area of ​​planting type i, in m 2 .

[0047] Specifically, for example, taking a densely planted bush in an office building in Shenzhen as an example, its carbon emission factor is 8.15 kgCO 2 / m 2 , the green area is 60000m 2 , then B C =8.15×60000 / 1000×55=26895 yuan.

[0048] Step 5: Establish a carbon emission operation benefit calculation model for buildings using new energy vehicles:

[0049] B Q =(Q 汽油车 -Q 电动车 )×P c =(EF 汽油车 ×AGC×M-EF 电动车 ×AEC×M) / 1000×P c

[0050] Among them, B Q Q is the carbon emission operating benefit of using new energy vehicles in buildings, in yuan; 汽油车 and Q 电动车 are the annual greenhouse gas emissions equivalent of gasoline vehicles and pure electric vehicles, in kgCO2 / a; EF 汽油车 and EF 电动车 They are the greenhouse gas emission factors of the energy cycle of the two vehicles respectively; AGC is the average gasoline consumption, the unit is L / 100km, AEC is the average electricity consumption, the unit is kWh / 100km, and M is the annual mileage, the unit is 100km.

[0051] Specifically, for example, in an office building in Shenzhen, there are 5 vehicles in total, and the total mileage of each vehicle is 50,000 km. The gasoline carbon emission factor is 2.2214 kgCO2 / L; AGC is the average gasoline consumption of 8L / 100km; AEC is the average electricity consumption of 15kWh / 100km. Then B Q =5×(50000 / 100×8×2.2214-50000 / 100×15×0.581) / 1000×55=1245.23 yuan.

[0052] Step 6: Establish a calculation model for the overall benefits of building carbon emissions operation:

[0053] B=B k +B C +B Q +B t

[0054] Among them, B is the overall benefit of building carbon emission operation, in yuan; B t It is the other carbon emission operating benefits of the building, in Yuan.

[0055] Specifically, for example, the overall carbon emission operating benefit of an office building in Shenzhen is B =

[0056] B k +B C +B Q +B t =92030.4+26895+1245.23+0=120170.6 yuan.
