Abstract：The energy consumption simulation of passive and active energy-saving technologies used in a zero-carbon building in a cold area was carried out by using Energyplus software,and the energy-saving effect was analyzed by comparing with the benchmark building.The results show that the use of high-performance envelope structure and intelligent shading technology can significantly reduce building energy consumption.The application of efficient cold and heat sources,fresh air heat recovery and solar photovoltaic systems can further reduce energy consumption.On this basis,the economic analysis of the simulation results is carried out,and the static investment recovery period is used as the evaluation index.The static recovery period of the zero-carbon building is 6.1 years,which has obvious advantages in energy consumption and economy.
