Abstract：Taking the university teaching building in Xiamen City as example，a method combining on-site measurements and simulation by DesignBuilder software wasadopted，the reliability of the model was verified by fitting the simulation data with the actual measurement data. 3 window renovation schemes （single-layer Low-E glass，hollow Low-E glassand hollow ordinary glass） were set to replace the original single-layer ordinary glass，and the energy-saving effects of diffrent types of Low-E glass were analyzed. For the teaching buildings with south and north corridors，2O working conditions were simulated to compare the energy consumptionbefore and after the renovation，in order to evaluate the applicability of Low-E glass The results show that after the renovation with Low-E glass，the energy consumption of the teaching building with south corridor is 5.6% lower than that with north corridor. Among 3 renovation strategies of hollow ordinary glass ， the energy-saving of the hollow Low-E glass reaches 21.9% ，while the energy savings of the other 2 strategies are less than 8.1% . By replacing the south facing external windows of the north corridor teaching building with hollow Low-E glass， energy saving reaches 15.9% . From the perspective of economic feasibility， the initial investmentofLow-Eglassisrelativelyhigh，and thecostisdifficult torecover within thebuilding's life cycle.
