AB - The energy consumption of prefabricated buildings under multi-layer building  materials system is affected by different weight factors. In order to  improve the level of energy consumption prediction, a method of energy  consumption prediction of prefabricated buildings under multi-layer  building materials system based on KPCA - WL SSVM is proposed. Taking indoor  ambient temperature, lighting conditions, utilization rate of electric  facilities, etc. as the combined weight of assembled building energy  consumption under multi-layer building materials system structure, the  energy consumption simulation and energy con­sumption allocation model of  assembled building under multi-layer building materials system structure  controlled by multi-component energy consumption parameter support vector  machine is established, and the support vector machine based on KPCA - WL  SSVM and principal component analysis dynamic fitting method are adopted.  The energy consumption parameters of prefabricated buildings under  multi-layer building materials system structure are detected and estimated,  and the energy consumption patterns, energy consumption distribu­tion with  different characteristics and energy consumption prediction model  parameters of prefabricated buildings under multi-layer building materials  system structure are obtained. Then, the emission factor and power  consumption factor prediction model of prefabricated buildings under  multi-layer building materials system structure is established, and the  dynamic prediction and evaluation of energy consumption of prefabricated  buildings under multi-layer building materials system structure are  realized. The test results show that the fitting degree of energy  consumption prediction of prefabricated buildings under multi-layer building  material system structure is high, the model optimization design of energy  consumption of prefabricated buildings is realized, the prediction accuracy  of building energy consumption is good, and the energy consumption can be  effectively reduced.
