In order to reduce building energy consumption and make wall insulation materials meet fire protection requirements, the authors put forward a kind of energy saving model of building exterior wall under green and energy saving nanomaterials. Mainly using PBECA energy saving calculation software. By setting up multi-component, multi-material method. The energy consumption of building aggregate in light energy saving device modified by nanomaterials is simulated and analyzed, and the energy consumption of building agent area is compared. The energy saving effect of light energy saving system modified by nanomaterial fly ash in prefabricated buildings was verified. According to the calculation of PBECA energy-saving calculation software, the annual energy consumption of the building assembled by nanomaterials modified fly ash lightweight energy-saving units is 5981 kWh, and the energy consumption per unit area is 35.01 kWh/m2. In the 1980's, the annual energy consumption of household agents was 86237 kWh, and the energy consumption per unit area was 50.42 kWh/m2. Through the analysis of the calculation results, it is concluded that the energy saving efficiency of replacing the light-saving wall with nanomaterials fly ash in precast area A can reach 65% of the energy saving standard.
