Linear heat transfer coefficient of structural thermal bridge-ψ is a key parameter in the building thermal design,but the design specifications provide a more general explanation about it.Therefore,it is necessary to further analyze ψ so that engineers or researchers can understand its connotation more deeply.Combining with relevant codes and standards,the computer energy-saving design software is utilized to analyze and simulate the algorithm and rationality of the value of the linear heat transfer coeficient.A practical project case is analyzed.By comparing the value changes of the two main linear heat bridges,the window opening and the outer wall air conditioner shelf,it is found that for buildings with a large number of linear heat bridges,the slight change of the linear heat transfer coefficient will have a negligible influence on the overall energy consumption of the building,so the coefficient in the thermal design of the building is crucial.The linear heat transfer coeficient in the engineering design ψ is drawn up.Correctly determining the linear heat transfer coefficient ψ will provide valuable reference for engineering design.
