Abstract：Shallow geothermal energy alternative to traditional energy is one of the effective paths to realize carbon emission reduction in the construction industry.Guizhou is rich in shallow geothermal resources,but the scale of development and utilization is insufficient,and the emission reduction potential and methods of shallow geothermal in buildings have yet to be expanded.Based on this,this paper refers to the China Certified Emission Reduction(CCER)voluntary emission reduction methodology CM-022-VO 1 standard to construct the CCER methodology of using geothermal energy to replace electric energy for heating and cooling,and uses EnergyPlus to simulate the actual operation data of an office building in a science and technology park in Guizhou Province in 2021,to demonstrate the feasibility of the methodology and to calculate the energy saving potential and carbon emission reduction of the shallow geothermal air-conditioning system of the building.The energy-saving potential of the system and the carbon emission reduction.The results show that the difference between the annual carbon emission reduction per unit area calculated by the method and the simulation results is only 0.05 tCO2e/a,which makes the method feasible.In addition,the annual carbon emission reduction per unit area of the building using the shallow geothermal energy project is 0.069 tCO2e/a,and the annual carbon benefit is about 124 600 RMB.
