摘　　要：建筑节能窗是能源损失的主要原因,提升节能窗的综合性能将极大地降低建筑能耗。现有节能窗生产设计存在设计与生产相脱节的现象,节能窗设计在追求结构和节能性能满足设计要求的同时,往往难以兼顾造价,使得节能窗的经济性不佳。基于多目标遗传算法,提出了结构性能、热工性能和成本造价3个目标优化函数,利用遗传算法对1.5 m×1.5 m标准窗型尺寸且采用5Low-E+9Ar+5+9Ar+5三玻两腔中空玻璃的新型高性能节能窗进行结构-性能一体化优化,给出了工程最优设计方案。综合考虑挠度变形、整窗造价和传热系数,当传热系数最低时,造价较低,中梃挠度变形较小,此时高性能节能窗具有综合最优的结构-性能指标,优化后的方案传热降低了3.6%,挠度变形减小了36.9%,造价降低了5.5%。Energy-saving windows are the main cause of energy loss. Improving the comprehensive performance of energy-saving windows will greatly reduce building energy consumption. The existing production design of energy-saving windows has the phenomenon that the design is divorced from the production. The design of energy-saving windows pursues the structure and energy-saving performance to meet the design requirements, but it is often difficult to take into account the cost, which reduces the economy of energy-saving windows. Based on the multi-objective genetic algorithm, three objective optimization functions of structure performance, thermal performance and cost are proposed. Using the genetic algorithm, the optimization design of a new type of high performance energy saving windows which use the standard window size of 1.5 m×1.5 m and 5 Low-E+9 Ar+5+9 Ar+5 insulating glass are carried out. The optimal design of the project is presented. Considering the deflection deformation, the whole window cost and heat transfer coefficient, when the heat transfer coefficient is the lowest, the cost is lower, and the deflection deformation of the mullion is smaller. At this time, the high-performance energy-saving window has the best structure performance index. After optimization, the heat transfer is reduced by 3.6%, the deflection deformation is reduced by 36.9%, and the cost is reduced by 5.5%.
