特色烟道塔：新型“贝壳式”花边，超轻、超薄的单面结构

光之塔是一座40米高的塔，为曼彻斯特市中心的一个新的低碳能源中心支撑和围住烟道。这个仿生结构建立在长达十年的创新和研究基础上，即由Tonkin Liu首创并与奥雅纳的工程师合作开发的贝壳花边结构。从自然界的几何形状中学习，该塔的形式就是它的力量。超轻、超薄的单面结构使用最少的材料来实现最大的效果。

The Tower of Light is a 40-metre tall tower supporting and enclosing flues for a new low-carbon energy centre in Manchester’s city centre. The biomimetic structure has built on the decade- long innovation and research, Shell Lace Structure, pioneered by Tonkin Liu and developed in collaboration with engineers at Arup. Learning from geometries in nature, the tower’s form is its strength. The super-light, super-thin single-surface structure uses the least material to achieve the most.

该塔由6毫米和8毫米厚的扁平钢板构成，经过裁剪、激光切割，然后焊接在一起，形成一个弯曲的坚固表面。使用先进的数字建模、分析和制造的现代施工方法，结合剪裁的原则，使贝壳花边结构的创新成为可能。这是迄今为止建造的最大的贝壳花边结构。

The tower is constructed from 6 and 8mm thick flat steel sheets, tailored, laser-cut, then welded together to create a curved stiff strong surface. Modern methods of construction using advanced digital modelling, analysis, and fabrication, combined with principles of tailoring, have made the Shell Lace Structure innovation possible. This is the largest built Shell Lace Structure to date.

能源墙是一个63米长、4-6米高的街道立面，包围着新的能源中心。釉面陶瓷砖反映了天空中云层的光线和运动，以及街道上行人和车辆的喧嚣。棋盘式的菱形瓷砖图案唤起了地球运动的动态能量，正如海浪在沙滩上留下的图案一样。

31种不同的瓷砖类型产生的起伏在高度上增加，总共有1373块瓷砖。新能源中心大厅包含在一个受自然启发的结构中，可以通过一个长的带状窗口看到其技术工作。

The Wall of Energy is a 63-metre long, 4- 6 metre height street fac?ade enclosing the new energy centre. The glazed ceramic tiles reflect light and movement from the clouds in the sky, and the hustle and bustle of pedestrians and cars on the streets. The tessellated interlocking lozenge tile pattern evokes the dynamic energy of earth’s movements, as seen in patterns left in the sand by ocean waves. The 31 different tile types produce undulations that increase in height, across a total of 1373 tiles. Contained within a structure inspired by nature, the technological working of the new energy centre hall can be viewed through a long ribbon window.

光明塔的照明使用了最少的能源。白天，塔内抛光的反射器在风中移动，将阳光反射到塔内的房间，使塔内充满了移动的光线。在夜间，LED灯对准反射器，每隔一刻钟就会创造出生动的、程序化的灯光序列，标志着时间的推移。

能量墙反映了移动的云彩和街道上的汽车车灯的光线，并在夜间以综合编程的方式进行动画。在一年中的标志性日子里，塔和墙都会用彩色的灯光照亮，以纪念文化庆典。

Minimal energy is used to light the Tower of Light. During the day, polished reflectors inside the tower move in the wind, to reflect sunlight into the tower’s chambers and fill the tower with moving light. During the night, LED lights directed at the reflectors create animated, programmed light sequences every quarter of an hour, marking the passage of time. The Wall of Energy reflects the light of moving clouds and car headlights on the street, as well as being animated with integrated programmed light at night. On landmark dates across the year, the Tower and Wall are illuminated together with colours to mark cultural celebrations.

Tonkin Liu与当地的制造商合作，完成了塔和墙的设计。塔是由Shawton工程公司制造的，在那里，最后的缝合焊接是由两位经验丰富的焊工来完成的。这些瓷砖是由英国最古老和最受尊敬的陶土公司之一达尔文陶土公司制造的。

Tonkin Liu worked with locally-based fabricators to deliver both the tower and the wall. The tower was fabricated by Shawton Engineering, where the final stitch-welding was reserved for the most experienced hands of two veteran welders. The ceramic tiles were fabricated by Darwen Terracotta, one of the UK’s oldest and most respected terracotta companies.

随着公民区热网（CQHN）和能源中心的开放，曼彻斯特中心的主要公民建筑通过2公里长的埋藏式绝缘管道和电力电缆网络获得了低碳能源。能源中心包含一个高效的3.3MWe热电联产发动机和两个备用的12MW燃气锅炉，该中心有能力纳入未来的低/零碳能源技术，包括使用绿色气体、氢燃料和热泵。

发电的热电联产发动机产生的热量被用来制造热水，通过绝缘的区域管道分配到整个城市。该技术改善了能源，有助于实现该市到2038年成为零碳城市的目标。

With the opening of the Civic Quarter Heat Network (CQHN) and Energy Centre, key civic buildings in the centre of Manchester are provided with low carbon energy through a 2 km network of buried, insulated pipes and power cables. The Energy Centre contains a highly-efficient 3.3MWe CHP engine with two back-up12MW gas boilers, The centre has the capability to incorporate future low/zero-carbon energy technologies, including the use of Green Gas, Hydrogen Fuel, and Heat Pumps. without disruption to the supply. Heat from the power-generating CHP engine is harnessed to create hot water, distributed through the insulated district pipework across the city. The technology improves energy, contributing towards the city's goal of becoming zero carbon by 2038.

完成的光之塔和能源墙创造了进入曼彻斯特历史区的一个突出的新门户。它们共同构成了一个整体的能源地标，使社区参与到曼彻斯特的低碳目标和气候变化行动计划的核心创新技术中。

The completed Tower o f Light and Wall of Energy create a prominent new gateway into Manchester’s historic district. Together they form a holistic energy landmark that engages communities with the innovative technologies at the heart of Manchester’s low-carbon ambition and Climate Change Action Plan.
