During the energy-saving optimization of office buildings,if the factors of influencing energy consump-tion cannot be mastered in time,it will directly reduce the optimization effect.Considering the above factors,this paper proposed an energy-saving optimization method for office buildings based on BIM model.Firstly,a BIM finite element model was built.Based on the model,specific analysis was carried out on the factors of influencing energy consumption.Then,Design Builder software was imported into the BIM model to simulate the sample collection of in-fluencing parameters.Moreover,the sample was trained,and then the trained regression function was used as one of the optimization objectives for building energy consumption.On this basis,the indoor comfort adaptability function of building was introduced as another optimization objective.Meanwhile,NSGA-II was used to optimize the objective,thus obtaining the optimal solution for optimization objectives.Finally,the energy-saving optimization of office build-ings was realized.The simulation results show that this method has better optimization effect,so it is conducive to im-proving the energy-saving effect.
