A control method of energy consumption of thermal insulation material for exterior wall of green building based on load prediction

In order to achieve the expected goal of building low energy consumption and optimising building thermal comfort, this study proposed a heat insulation energy consumption control method based on load prediction for external wall insulation materials of green buildings. First, make the building energy consumption data more regular through standardised processing and by storing it in different nodes. Then, the energy consumption characteristics are obtained by principal component analysis method. In addition, the heat transfer coefficient of exterior wall insulation material is obtained by the way of load prediction, so as to reduce the heat dissipation of exterior wall insulation material without sacrificing the comfort. According to the test data, the total energy consumption of this method is low, the maximum value is only 29 kJ, and the thermal comfort evaluation score is high, which fully reflects the effectiveness of this method.
