光之塔是一座40米高的塔，用来支撑和封闭曼彻斯特市中心低碳能源中心的烟道。这个仿生结构建立在长达十年的创新和研究基础之上，其贝壳花边结构由Tonkin Liu开创，并与奥雅纳的工程师合作研发而成。塔的形式借鉴了自然中的几何结构，这也是其优势所在。超轻、超薄的单面结构用最少的材料达到最大的效果。该塔采用6毫米和8毫米厚的钢板，它们经过剪裁和激光切割，焊接形成坚固的弯曲表面。使用先进的数字建模、分析和制造的现代施工方式，结合剪裁原则，使贝壳花边结构的创新成为可能。迄今为止，该项目是最大的建成贝壳花边结构。

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. 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.

能源墙是一道围合能源中心的63米长、4至6米高的街道立面，其釉面瓷砖反映了云层的光线和运动，以及街道上行人和汽车的喧嚣。镶嵌式菱形瓷砖的交错图案模拟地球运动产生的动态能量，如同海浪在沙滩上留下的印记。瓷砖共1373块、31种类型，通过高度变化形成表面起伏。受自然启发的结构包裹着新能源大厅，人们可以通过带状长窗看到其中的技术工作。

The Wall of Energy is a 63-metre long, 4- 6 metre height street façade 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.

光之塔的照明使用了最少的能源。白天，塔内的反射镜随风而动，将阳光反射到塔室，使塔内充满灵动的光线。夜间，LED灯照向反射镜，每隔十五分钟就会产生动态的、程式化的灯光序列，标志着时间的流逝。在重要的日子里，塔楼和围墙都会披上彩色灯光，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. On landmark dates across the year, the Tower and Wall are illuminated together with colours to mark cultural celebrations.

Tonkin Liu与当地制造商合作交付了塔楼和围墙。塔楼由Shawton Engineering制造，最后的缝焊交给两名经验最丰富的焊工。瓷砖由Darwen Terracotta公司制造，该公司是英国最古老、最受尊敬的陶土公司之一。

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.

随着市政区供热网络（CQHN）和能源中心的开通，曼彻斯特市中心的主要市政建筑通过2公里长的埋地绝缘管道和电力电缆网络获得低碳能源。能源中心包含一台高效的3.3MWe CHP发动机和两个备用的12MW燃气锅炉，该中心有能力整合未来的低/零碳能源技术，包括使用绿色气体、氢燃料和热泵。CHP发动机产生的热量被用来产生热水，并通过绝缘的区域管道输送至整个城市。该技术改善了能源结构，有助于实现该市在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. 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.

完工后的光之塔和能源墙为曼彻斯特历史街区打造了重要的新门户，共同构成能源地标，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。曼彻斯特市议会环境执行委员Tracey Rawlins说：“市政区供热网络是一个开创性的系统，它展示了曼彻斯特减少碳排的决心。作为理事会，我们致力于在限制气候变化带来的影响上发挥全部作用，因为我市力争在2038年实现零碳排的目标，这个目标比国家目标至少提前了12年。这是一项复杂的挑战，但像该供热网络般的雄心之作表明我们正在采取行动。因此除了看起来很漂亮，我们希望光之塔能成为这类作品的标杆。”

The completed Tower of 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. Tracey Rawlins, Executive Member for Environment for Manchester City Council, “The Civic Quarter Heat Network is a trailblazing system which demonstrates Manchester’s determination to cut our carbon emissions. As a Council we are committed to playing our full part in limiting the impacts of climate change as the city strives to become zero carbon by 2038 – at least 12 years ahead of the national target. It’s a complex challenge but ambitious projects such as this network show that we are taking action to rise to it. As well as looking beautiful, we hope that the Tower of Light will be a beacon for this kind of work.”
