| Abstract: | In this study, a demonstration center of a near-zero energy building in a cold region was selected as a case to carry out the life-cycle carbon emissions accounting of the near-zero energy building. Numerical simulation method was used to select the type of building thermal insulation material, thickness of thermal insulation material, window type, window-wall area ratio, form of heating and air conditioning and building service life, and analyze the influencing factors of carbon emissions in the whole life cycle of the building. The results show that the carbon emissions in the production and transportation, construction, operation and demolition and cleaning stages of building materials account for 51.3%, 1.3%, 47.3% and 0.1%, respectively, in the whole life cycle of near-zero energy buildings. Compared with other buildings, it is found that with the improvement of building energy saving requirements, carbon emissions in the production stage of building materials account for more and more; One-third of the life cycle carbon emissions of near-zero energy buildings are about one-third of ordinary buildings, and one-third of green ones; Through the use of low-carbon environmental protection materials, insulation material thickness between 160-260 mm, window-wall area ratio between 0.1-0.2, solar+ground source heat pump energy supply mode and prolonging the service life of the building can reduce the carbon emissions in the whole life cycle of the building. |
