Abstract:In view of the high energy consumption of ordinary glass in residential buildings，it was proposed to replace ordinary glass with tempered vacuum glass to reduce building energy consumption.By means of laboratory testing and numerical simulation，the thermal conductivity of new tempered vacuum glass was measured and calculated，and the energy consumptions of residential buildings with different types of glass in different thermal zones were compared and analyzed.The results showed that the thermal conductivity of tempered vacuum glass（TVG） was much lower than that of common architectural glass such as single glass （SG6），insulating glass（IG），and three-layer laminated glass（3LG）.Compared with the energy consumption of single glass in residential buildings，the energy efficiency of tempered vacuum glass was the best， which was 2~3 times of the annual energy saving rate of other types of glass.With the increase of latitude of thermal zone in residential buildings，the heating load increased gradually and the cooling load decreased continuously.No matter in which thermal zone，the cooling/heating load of residential buildings using tempered vacuum glass was less than that of other types of glass.The use of tempered vacuum glass in residential buildings had significant energy-saving effects，which had positive practical significance for the green development of residential buildings and the realization of the national “dual carbon” goal.
