基于双层玻璃幕墙节能设计
[摘要]建筑幕墙作为建筑的外围护结构，其热工性能直接影响建筑能耗。现在广泛使用的单层玻璃幕墙，虽然逐渐采用热反射镀膜玻璃、中空玻璃、断热型材等其它节能材料，在热工性能方面比过去的门窗有所改善，但仍然存在能耗较大的问题。最近几年发展的双层玻璃幕墙以其科学的结构、完善的功能、先进的设计理念，充分利用太阳能、自然通风换气，降低空调能耗，减少风及恶劣气候的影响，营造舒适温馨的生活和工作环境等优点，越来越受到建筑师和投资者的青睐。

[abstract] Architecture curtain wall as the outside of the building the structure, its thermal performance directly influence the building energy consumption. Now the extensive use of single glass curtain wall, although the gradually hot reflex coated glass, hollow glass, break hot profiles other energy-saving materials, in the thermal performance aspects of the doors and Windows of than in the past has been improved, but still exists the problem of large energy consumption. In recent years the development of double deck glass curtain wall with the scientific structure, perfect function, advanced design concept, make full use of solar energy, natural and ventilated take a breath, reduce the energy consumption of the air conditioning, reduce the wind and bad the influence of climate, and create a comfortable warmth in life and working environment and other advantages, more and more get the favour of architects and investors.

1 引言
双层玻璃幕墙，又称为热通道幕墙、气循环幕墙、呼吸幕墙、生态幕墙、绿色幕墙或者主动式幕墙等（以下简称DSF），它由两层玻璃幕墙加上二者之间的热通道组成，在通道的上下两端设有风口，通道的高度可以是一个或者多个层高。20 世纪90 年代，双层玻璃幕墙已在欧洲多个国家得以广泛应用，它对提高玻璃幕墙的保温、隔热、隔声功能有很大的作用。当前，节能和环保已经成为世界的两大主题，社会对建筑节能的意识也在逐渐增强，建筑围护结构作为建筑节能的主要部分，更是显得尤为重要。为此，本文针对环保节能型的双层玻璃幕墙展开相关的探讨。
