不同类型的玻璃幕墙能耗影响分析研究

Analysis and Research on the Influence of Different Types of Glass Curtain Walls on Energy Consumption of High-rise Buildings

针对不同类型玻璃幕墙能耗影响不确定、研究困难等问题,利用Revit软件构建高层建筑模型,选取6种玻璃幕墙为研究对象,采用度日能耗分析法进行能耗分析,结合有效传热系数法验证结果。通过求解离散数据微分方程获取加权系数,进行动态能耗分析,并引入热平衡法进行二次验证。结果表明:单层玻璃幕墙能耗普遍高于双层玻璃幕墙能耗,相较之下年静态能耗约高出29%,冬季静态能耗约高出22%,夏季静态能耗约高出24%;单层玻璃幕墙中浮法玻璃幕墙的节能效果最好,相应的浮法玻璃+浮法玻璃组合的双层玻璃幕墙节能效果最好。

In response to the uncertainty and research difficulties in the energy consumption impact of different types of glass curtain walls,a high-rise building model was constructed using Revit software.Six types of glass curtain walls were selected as the research objects,and the daily energy consumption analysis method was used for energy consumption analysis.The results were verified by combining the effective heat transfer coefficient method.By solving discrete data differential equations to obtain weighting coefficients,dynamic energy consumption analysis is conducted,and the thermal equilibrium method is introduced for secondary verification.The results show that the energy consumption under single-layer glass curtain walls is generally higher than that under double-layer glass curtain walls.In comparison,the annual static energy consumption is about 29%higher,the winter static energy consumption is about 22%higher,and the summer static energy consumption is about 24%higher.The energy-saving effect of float glass curtain walls is the best in single-layer glass curtain walls,and the corresponding double-layer glass curtain wall with a combination of float glass and float glass has the best energy-saving effect.
