Abstract：The energy-saving effect evaluation of thermal insulating coatings in different seasons and different periods was realized by using the comparison method,through the standardization,assembly test room and intelligent monitoring and control sys-tem.On this basis,a set of energy-saving evaluation method and parameters system for thermal insulating coatings was established.T/CSTM 00292-2021"Energy-saving evaluation method for building insulating coating"was developed.In order to facilitate ener-gy-saving applications,how to use the correction factor of heat transfer coefficient to calculate the equivalent thermal resistance of the coatings was analyzed on the basis of the standard method.Finally,the energy-saving effect of aerogel insulation coating system in hot summer and cold winter zone was evaluated according to the standard method.The results indicated that the aerogel ther-mal insulation coating system has a significant energy-saving effect in the hot summer and cold winter zone compared with the white coating with the same color and lightness.The relative energy-saving rate in summer is 13.3%,and the correction factor of heat transfer coefficient is 0.86.The relative energy-saving rate in winter is 4.7%,and the correction factor of heat transfer coeffi-cient is 0.95.The annual relative energy-saving rate is 6.8%,the correction factor of heat transfer coefficient is 0.93,and the e-quivalent thermal resistance is 0.40(m2·K)/W.
