The future envelope -towards a more reactive facade

Hybrid Tectonic 3D seamless metal facade

Thin Sheet Metal Facade Cladding System for Hyperbolic surfaces using Composite Susbtrates E-Grow developed a method for constructing metalclad, double-curved surfaces, such as undulating walls, roofs or any other exterior and also interior architectonics. The goal of this multi-layered system is to minimize the cost of building such exterior envelopes and interior applications. The outermost layer of this envelope system consists of waterproof overlapping metal shingling. Thickness of shingles are dramatically less than ordinary metal shingles (at 0.1mm-0.2mm), reducing the cost and weight of the cladding. 3M VHB structural strength tape is used to to attach the thin gauge metal shingles (stainless steel, titanium, copper and other metals) to a Glass Fiber Reinforced Gypsum (GRG) base with waterproofing membrane in between for moisture barrier for additional protection. The substrate of this multi-layered system is produced through another innovative patented procedure by E-Grow. The CNC routed recyclable wax mould enabled GRG to be carried out with higher precision and smaller tolerance levels and using the same mould used for complex geometry reduces cost. Thinner GRG layers connected to steel framework, works as an integrated sandwich system, leaving enough space for duct work and space for maintenance.

Performance as a goal, integration as the approach

建筑表现为宗旨 技术整合为方法

Introduction As parametrics blend more into architecture practice, results are seemingly random, abstract, complex and often hyperbolic shapes. This eventually made metal cladding as building envelope of choice for facade. Metal is also quite successful on accentuating the geometry of free-form designs, enhancing the affect at the same time providing adequate weather protection. On the flipside, traditional bending and curving process of the metal, based on geometric partitioning that can not be easily resolved, as doing so will push the cost too high. On the other hand machining for double curvature surfaces in metal facade construction are difficult and the machining might result uneven distribution of mechanical stress or require calibrating the right machinery pressing pressure for certain metals. All these parameters contribute to the complexity in controlling the quality of the overall result. As response, the 3D metal facade system developed by E-grow attempt to solve the above mentioned problems and improve productivity and reducing cost as the main goal. Metal has long been known for its sustainability, longevity, low maintenance requirements, and superior exterior performance. E-Grow is taking those benefits to a new level benefiting from innovation in composite materials, adhesives and weather barriers. With the unique ability of individual panel to be field-assembled, application of cladding or replacement becomes easier. Watertight shingle metal Panel Systems are the next generation of metal cladding. The thermal Movement is tolerated though the 3M VHB elastic adhesive tape, an essential layer of “detailing� this metal cladding system.

Semi-monocoque aluminum construction


Monocoque construction is defined as a structural system in which the load is taken up in the skin rather than the framing. Semi-Monocoque constructions are hybrids of these two originated in aircraft Semi-monocoque construction comes from shipbuilding where it is often realized in steel or aluminum. Because of its prohibitive fabrication cost, monocoque construction is typically used for situations where extreme lightness is critical, making aluminum the material of choice. In this technique a 3D digital model is given to the contractor. The geometry is then rationalized into developable strips of metal, in this case of 6mm aluminum. The aluminum is then welded unto a

custom aluminum frame. These form one structural continuous structural unit. The seams of the panels are then filled and the entire surface posished to hide the seams. The entire structure is then air brushed with marine paint and covered with a gelcoat to prevent damage and tarnishing. Every single piece is custom fabricated in this method and requires a great deal of labor to finish and to fix because of the material thickness. This method also requires the surface to be finished since otherwise the aluminum will tarnish with time. Because the piece is constructed as a single hull the installation techniques difficult and extremely customized.


三维冲压满焊抛光是船模或飞机生成的模式。 此工艺利用超6mm厚铝板小块冲压整形拼接。在此研究中使用6mm厚的厚铝板,利用焊接(亚 弧焊、满焊处理)使其成为一个连续的造型面,接着经过打磨抛光以隐藏接缝,使其渐渐成为三 维造型的外壳,最后使用船舶漆和胶衣覆盖在表面以违美观及防腐。 此工艺每一片都需要客制化的制作亟需仰赖人工及机具,且因为板材的满焊和打磨导致人工的大 量耗费。整个工艺过程耗时耗工,造价庞大。


3D Custom Panel System

Experience Music Project, Seattle. 2000 FABRICATION\ Hoffman Corp. ARCHITECT\ Gehry Partners LLP. MATERIAL\ Stainless Steel Sheet Custom Steel Framing VALUE\ USD$2800 m2

The majority of the main structural elements are custom fabricated which gives greater precsion to the surface but also increases the cost substatially. Every single piece of cladding is custum cut in this method. This produces more waste and requires a great deal of organization from the fabrication to the installation which increases cost. Fabrication -The custom steel framing is quite expensive since each needs to be molded seperately -Attathing the skin to the frame -Water-proofi ng is done in two layers because of the difi culty of precision in the surface layer.

在结构上贴上表层肌肤; 防水要在两个层面进行,因为在表层制作防水层有难度,因此需要使用双 层外墙(Double Skin Facade)。 大部分的主要结构要素是客制化加工以增加表面的精度,但也因此使得成 本大幅增加。 在此工法中,每一个单件都是使用客制化消减,导致产生大量的废弃物, 造成浪费。 从加工一直到安装的建造过程,需要一个大组织团队的参与;使得人事成 本增加。 施工误差大、曲率太小,拉弧不顺,必须做内防水层,外观会有许多铆钉 头外露也易造成积灰层不易清洁 。

This method is the least precise of the three although it is still extremely involved and expensive. The steel elements are all standard, variation is introduced through controlling the lengths and the custom manufacture of the joints. Fabrication -Custom joints allow for standardized elements -Because the surfaces are rationalized as straight elements it requires extremely layered systems of secondary structure to achieve the desired curves -Attaching the skin to the frame is quite complex -Water-proofi ng is done in two layers because of the difi culty of precision in the surface layer.

客制化不锈钢双曲面用折、冲压模式进行加工制造。 需要次级结构的分层系统以实现所需要的曲面,即需要将钢骨结构分割成若干段并加以连接以达到曲 面的效果。 在精准框架上挂表面肌肤相当复杂 防水要在两个层面进行,因为在表层制作防水层有难度。 此工艺相较下较不精准,但依旧需要大量人力的参与以及成本的耗费。 钢结构的元素都是标准且精准的,控制每一段钢骨的长度以及客制化制造的节点是变化的关键。 此系统精度要求高,施工调平困难,必须施作内防水层,费时费工。
