Abstract: In order to better control the total amount of indoor environmental pollutants, a control method of indoor environmental pollutants in intelligent buildings based on dynamic CGE was proposed. Indoor air quality detector was used to collect the sample data of indoor environmental pollutants in buildings, and then a dynamic CGE model was established to extract the spatial and temporal distribution characteristics of pollutants. According to the feature extraction results, the diffusion process of indoor air pollutants was analysed, and the concentration of indoor pollutants was detected with the phenol reagent method. Based on this, the inlet and outlet air volume of the fresh air system was adjusted to complete the total control of indoor environmental pollutants in the intelligent building. Experimental results show that the precision value of indoor pollutant diffusion detection by the proposed method is as high as 0.98, and the concentration of pollutants can be well controlled.
