ADoutput electricityRepresenting an amount of output power;
EFelectric powerRepresents the average carbon dioxide emission factor of the power.

ADoutput electricityRepresenting an amount of output power;
EFheat generationRepresents the average carbon dioxide emission factor of the heat.
In this embodiment, the electric activity data is based on the electric meter readings settled by the enterprise and the power grid company or the energy consumption account or the statistical form of the enterprise.
The thermal activity data takes a thermal purchasing and selling settlement voucher or an enterprise energy consumption accounting or a statistical statement as the basis.
The non-caloric units can be converted into caloric units as follows:
a) hot water, measured in units of mass, can be converted to units of heat according to the following formula:
ADhot water＝Maw×(Tw-20)×4.1868×10-3
Wherein, ADHot waterRepresents the heat quantity of the hot water;
Mawrepresents the quality of the hot water;
Twrepresents the hot water temperature;
