Thermal insulation and energy efficiency of building external walls optimized based on heat transfer performance model
In order to improve the energy saving effect of building exterior wall insulation,a heat transfer perfor-mance model was introduced to simulate the heat transfer process of the building,the energy saving potential of the building was identify,and improvement suggestions were provided to reduce energy consumption and carbon emis-sions.Design a building heat transfer performance model to simulate the heat transfer process of the building.Based on the heat transfer performance model,the sensitivity analysis method was used to obtain the heat transfer coeffi-cient and radiation absorption coefficient of the exterior wall.With the goal of minimizing energy consumption and minimizing costs,a energy-saving optimization objective function was constructed.By considering structural design,material selection,and construction technology,the thermal conductivity of the wall substrate and insulation board were adjusted to solve the inconsistent expansion and contraction strength caused by differences in thermal conduc-tivity,and an energy-saving optimization plan for external wall insulation and thermal insulation were designed.The results showed that this method can effectively reduce the heating load,cooling load,and total load of buildings,im-prove building energy savings,and provide high energy efficiency for buildings.
