[0078] In step 206 , it is determined whether the indoor environment of the building meets the human comfort requirements; if not, step 207 is executed; if yes, step 208 is executed.

[0079] In one embodiment, it is possible to determine whether the indoor environment of the building meets the human comfort requirements based on the indoor airflow data of the building. The indoor airflow data of the building includes temperature data and relative humidity data. It is possible to determine whether the indoor environment of the building meets the human comfort requirements based on the temperature data and relative humidity data of the indoor airflow data of the building; if the temperature data of the indoor airflow data of the building is not within the set temperature range, and / or the relative humidity data is not within the set humidity range, it is determined that the indoor environment of the building does not meet the human comfort requirements, and step 207 is executed; if the temperature data of the indoor airflow data of the building is within the set temperature range and the relative humidity data is within the set humidity range, it is determined that the indoor environment of the building meets the human comfort requirements, and step 208 is executed.

For example, a ventilation device, one of the indoor related devices, outputs electrical energy, which is provided by a hydroelectric power station. By setting the weight of the energy consumption data of the ventilation device, the carbon emissions of the ventilation device are truly reflected when calculating the carbon emissions.

[0092] Furthermore, the method for calculating the carbon emissions of a building shown in the embodiment of the present application obtains the indoor airflow data of the building based on the meteorological data of the building, and CFD calculates the wall thermal boundary conditions and the incoming wind boundary conditions of the building during the calculation period, so that the indoor airflow data of the building obtained by CFD calculation can change with the change of the meteorological data of the building, and the indoor airflow data of the building can be accurately obtained; when it is judged that the indoor environment of the building meets the human comfort requirements based on the indoor airflow data of the building, the calculated energy consumption data of the indoor related equipment of the building during the calculation period can also change with the change of the meteorological data of the building, thereby improving the accuracy of the energy consumption data; according to the energy source of each device in the indoor related equipment of the building, the weight of the energy consumption data of each device in the indoor related equipment of the building is set respectively; according to the weight and the energy consumption data of each device in the indoor related equipment of the building, the carbon emissions of the building during the calculation period can be accurately calculated, and the calculated carbon emissions can truly and accurately reflect the carbon emissions of the building.

[0093] Furthermore, the method for calculating the carbon emissions of a building shown in the embodiment of the present application obtains the setting parameters of the building through a geographic information system. The relevant parameters for calculating the carbon emissions are easy to obtain, which facilitates the calculation of the carbon emissions of the building. The obtained setting parameters are objective and true, and can accurately calculate the carbon emissions of the building during the calculation period.
