To manage the carbon emissions of zero carbon buildings, a building information model is used to construct a carbon emission model for zero carbon buildings, and a multi-objective optimization method based on non dominated genetic algorithm is developed to optimize the carbon emissions. The performance of the carbon emission model is analyzed using the China Energy and Carbon Emission Database (MEIC) public database, and the outcomes reveal that the data matching error rate of the model is less than 5%, and the model’s coverage of the whole span of carbon emissions reaches 87.9%. By reusing the data from Global Carbon Budget (GCB) database to predict the carbon reduction effect of the optimization plan, the outcomes reveal that the optimization plan can reduce the carbon emissions throughout the whole span by 35% to 45%, and the carbon reduction during the operation phase can reach 43.7%. From the above outcomes, the emission reduction plan based on carbon emission model and multi-objective optimization method can effectively reduce the carbon emissions. This can foster sustainable development, and provide ideas for carbon reduction plans in other fields.
