In the framework of dual carbon technology,there is a huge space for reducing building carbon emissions,and the traditional building energy consumption measurement can no longer meet the demand of energy saving and carbon reduction.In this paper,a refined estimation method of carbon emission index for green residential buildings is presented.This method based on the non-intrusive load identification results,measuring the energy consumption of electrical appliances,and calculating the indirect carbon emission factor by considering the time-varying power output of the building light storage system and the carbon emission per unit of electrical energy from the power grid.Then,considering the characteristics of electrical appliances,the direct carbon emission factor is estimated,and combined with the indirect carbon emission,the actual carbon emission is obtained.Finally,this paper uses the actual"source-load"data of residents to estimate the energy consumption carbon emission index,which provides data support for the energy-saving and carbon-reduction regulation strategy of buildings.
