Low-E玻璃在厦门某高校教学楼节能改造中的应用模拟
Simulation of Low-E Glass in Energy-Saving Renovation of University Teaching Buildings in Xiamen City
摘要
Abstract
Taking the university teaching building in Xiamen City as example,a method combining on-site measurements and simulation by DesignBuilder software was adopted,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 glass and hollow ordinary glass)were set to replace the original single-layer ordi-nary glass,and the energy-saving effects of different types of Low-E glass were analyzed.For the teaching buildings with south and north corridors,20 working conditions were simulated to compare the energy con-sumption before 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 investment of Low-E glass is relatively high,and the cost is difficult to recover within the building's life cycle.关键词
