Forming part of the National Space Science Centre, this 42-metre-high exhibition tower adopts the aesthetics of space travel. Stretched between a lightweight steel structure, the facade consists of three-layer ETFE-membrane cushions 3 m high and up to 20 m in length. The polythene material is resistant to UV radiation and has a self-cleaning surface. With a gridded coating it was possible to achieve varying degrees of transparency. Although the material has an expected life of 60 years, the fixings are designed to facilitate the replacement both of individual cushions and of the existing rockets with new ones. The three-dimensional curved form of the tower and the lightweight facade material allowed the legible steel structure to be reduced to a minimum.

由于ETFE具有极好的透光性能,因而特别适合用来建造需人工模拟自然环境的建筑场所如动植物园、人工雨林等。从建于80年代初的jungle house到2001年的伊甸园再到几个月前刚建成的Masoala 雨林,都堪称这方面的代表之作。
就造价而言,虽然ETFE气垫的价格不比玻璃低,但由于其质量极轻,因而在整体结构及基础方面的节省还是相当可观的。

结构特点

1. ETFE膜材可以大尺度的加工,与传统的屋面覆材相比,可以用于更大跨度的结构.这给工程人员提供了整合屋面覆材和主体结构设计的机会,同时发展简单化和典雅风格.

2. 由于ETFE膜材本身的韧性, 高抗拉强度,超过300-400%的延展性范围,使得FTFE系统能够自然的应付非常大的结构误差.

3. 由于独一无二的轻质特性, 可以用于更新结构的开发和应用,比如Uniaxial cable nets and large scale geodesics.

环境(阳光)控制和可变表皮

1.ETFE的多层膜材构造,可以被开发成气候(感应)的(建筑)外维护体系: 这可以通过感应环境的变化,并改变其自身的绝缘(保温)性亦即阳光投射率来达到.

2.多层膜材通常可以用重叠印刷图案在不同的层面上,通过整合气枕和精密的充气系统,达到控制投射率的目的.

3. 这样的技术不仅仅可以控制阳光透过率,也同时带来了不同的外观.

4气枕和精密的充气系统的结合,不仅仅可以改变气枕内部的压力(number of air chambers),也改变了热传导系数(U value)

Project:
Duales Pavilion

Location:
Hannover Expo 2000, Germany

Architect:
Atelier Brückner

Size:
1,800 sqm

When:
2000

Notes:
For the World Exposition 2000 in Hannover, Germany, the "Duales System” (a German recycling project) had a pavilion that utilized Texlon Foil Systems for both wall and roof envelopes.

The wall system had a positive/ negative leaf pattern printed on the outer two of the three-layer system. These foil cushions, with a 3% pattern overlap, were pneumatically able to transform the wall envelope from a translucent to an opaque system - allowing for the dramatic presentation of a tornado to be performed within.

After each performance, the wall then transformed back to a 45% transparent state. The roof of this pavilion was one of the world's largest foil cushions, over 25m in diameter, and featuring a series of fabric tubes within the system that could expand or contract to adjust transparency of the system in relation to the performance.

The Texlon system was selected not only for its variable transparency technologies but also for its ecological characteristics. Not only are the materials in Vector Foiltec's system “green” but even more profound are the sustainable design opportunities afforded.

The foil products have an extremely low energy consumption during their manufacturing process; and the complete system weighs between 50 and 90 percent less than systems made from other materials with comparable properties - further conserving on the structural system needed to support the cladding.

Part of the system is manufactured from recycled materials and the entire system can ultimately be returned to our facility to be recycled at the end of the project's life. The Architect can explore green or sustainable design solutions for responsive, intelligent day lighting and dynamic thermal properties that can alter spatial characteristics and building performance.

ETFE 与其他含氟聚合物的比较

尽管Fluon[$reg]ETFE 在化学品防护性,耐热性和电性能方面略逊色于PTFE(聚四氟乙烯) PFA, 可是与其他的热塑性含氟聚合物,如PVdF(聚偏氟乙稀), ECTFE(三氟氯乙烯)比较,它是一种有很好的稳定性的含氟聚合物

ETFE的建筑是很漂亮,本人曾对ETFE 材料进行过力学性能方面的研究!
