光之塔高40米，其建造是为了支撑和封闭曼彻斯特市中心的新低碳能源中心的烟道。这座仿生结构建立在长达十年的创新和研究基础上，建筑贝壳一样的花边结构由Tonkin Liu开创，并与奥雅纳的工程师合作开发而来。高塔的外形从自然界的几何形状中获得灵感，这也是其优势所在。超轻、超薄的单面结构使用最少的材料，发挥最大的效果。该塔由6毫米和8毫米厚的扁平钢板构成，经过定制，激光切割，焊接形成弯曲的刚性坚固表面。使用先进的数字建模、分析和制造的现代施工方法，结合剪裁原则，使贝壳花边结构的创新成为可能。这也是迄今为止建成的最大的贝壳花边结构建筑。
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.

能源墙是一面63米长，4-6米高的街道立面，将新能源中心包围在内。釉面瓷砖反射着天空中云层的光线和运动，以及街道上行人和汽车的喧嚣。镶嵌式菱形互锁瓷砖图案引发人们对地球运动产生的动态能量的想象，仿佛海浪经过，在沙滩上留下的痕迹。31种不同的图块类型在1373个砖块中随高度变化形成起伏。新能源中心大厅位于受大自然启发的结构中，来访者可以通过长长的带状窗户向内观看。
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.

点亮光之塔消耗了最少的能源。白天，塔内抛光的反光板随风移动，将阳光反射到塔的腔室中，并使塔充满活动的光线。夜间，LED灯指向反光板，每过一刻钟，就会出现动态的编程光序列，标记时间的流逝。在一年中具有纪念意义的日子里，塔楼和城墙会被不同色彩的光照亮，以纪念文化庆祝活动。
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与当地的制造商合作，交付了塔楼和墙壁。高塔由Shawton Engineering制造，最后的缝合焊接经由两位资深焊工最有经验的手完成。瓷砖由英国历史最悠久，最受尊敬的陶土公司之一Darwen Terracotta制造。
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.

随着市政区热网（CQHN）和能源中心的开放，曼彻斯特市中心的主要市政建筑通过2公里的埋地绝缘管道和电力电缆网络提供低碳能源。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。来自发电热电联产发动机的热量被利用来产生热水，并通过整个城市的隔热区域管道分布。该技术改善了能源结构，为本市在2038年实现零碳目标做出贡献。
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.
完工的光之塔和能源墙为曼彻斯特历史街区创造了一个亮眼的新门户。它们共同构成了一座能源地标，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 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.
曼彻斯特市议会环境执行委员Tracey Rawlins表示：“市政区热网一个开创性的系统，展示了曼彻斯特减少碳排放的决心。作为理事会，我们致力于在限制气候变化影响方面发挥全部作用，因为本市将努力在2038年实现零碳目标——比国家目标提前至少12年。这是一项复杂的挑战，但像该热网这样雄心勃勃的项目表明我们正在采取行动。除了看起来漂亮，我们还希望光之塔将成为这类项目的灯塔。”
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.”
