The results show that the energy consumption under single layer glass curtain walls is generally higher than thatunder double-layer glass curtain wals.In comparison，theannual 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 efctffoat glasscurtainwallisthebstinsingle-layerglasscurtainwalls，andthecorespondingdoubl-lar glass curtain wall with a combination of float glass and float glass has the best energy-saving effect.

我國建筑業(yè)正逐漸向著智能化、綠色化方向發(fā)展，高能耗建筑在建筑工程中的比例也在逐漸增加，玻璃幕墻是目前高層建筑常采用的圍護(hù)結(jié)構(gòu)之一，其獨(dú)特的建筑美學(xué)效果使其被廣泛應(yīng)用，但大面積玻璃幕墻增加了建筑的能耗，在倡導(dǎo)建筑節(jié)能的新時(shí)代下，針對(duì)不同類型玻璃幕墻對(duì)高層建筑能耗影響分析具有極其重要的意義。（剩余5000字）
