Abstract：In order to study the carbon reduction potential of different green building technologies in the operation stage of residential buildings,CEEB software was used to establish standard models for typical residential buildings in different climate re-gions,and the influence degree of different technologies on the carbon emission intensity of buildings was obtained through carbon emission simulation.The results show that the contribution level of different technologies to reducing the carbon emission intensity of residential buildings is less affected by climate regions and building types.Among them,the carbon reduction potential of im-proving the energy efficiency of air conditioners is the greatest,and the emission reduction rate of level 1 energy efficiency air conditioning with rated cooling capacity≤4500 W can reach 10.51％～12.36％;Followed by natural lighting passive technology,solar hot water technology and photovoltaic power generation technology,the emission reduction rates can reach 7.77％～12.36％,5.39％～10.03％and 5.28％～5.90％respectively;The energy-saving technology of enclosure structure has a relatively small contribution to carbon reduction;Compared with conventional energy-saving buildings,the carbon emission reduction advantages of three-star green residential buildings are very obvious.Only in the building operation stage,the average carbon emission reduction of three-star green residential buildings can reach 17％at the lowest and 48％at the highest.
