最美校园,就在香港中文大学


完成时间:2015
设计单位:香港中文大学建筑学院


竹亭的高度相等于四层楼高、覆盖面积为350平方米、是一个可容纳二百个座位的大跨度弯曲主导网架结构。
整个网架结构以475枝大竹组成,竹在施工时屈曲,并以广东传统搭棚技术用金属线将竹扎紧。竹亭的外形由三角网格结构向下折叠而成,组成的三个空心柱固定于混凝土地基上,并盖上量身定做的亚加力纤维布料作遮挡风雨用途,射灯则从空心柱中擦亮整个竹亭。


竹亭在建筑业议会、香港中文大学建筑学院及众多承建商同心协力下完成。其由Prof. Kristof Crolla带领的中大建筑学院研究队伍所设计。这个研究探讨如何将计算设计工具套用于现行实际施工模式从而减少其对建筑设计的限制。新颖的设计体现出竹棚建筑无限的可能性,也希望给青黄不接的搭棚业一个展现精湛技艺的新天地。
竹亭的设计最初源于一个由中大建筑学院举办,建筑学生参与的设计工作坊所提出的概念方案。后来由研究团队、结构工程师、竹顾问利用电脑结构模拟程式、建筑模型和大比例样板共同研发完成。


竹子是非常普及和环保的物料,在亚太地区,非洲和美洲更是长得快又茂盛。竹也是很好的可再生自然资源,除了生长过程可将二氧化碳转化为氧,也是强,轻,易于加工和运输的建筑材料。在香港,竹大多出现于戏棚,临时棚架,和民间节庆的庙宇中。世界上,它通常用作木材或钢的替代品,都没有利用竹的独特弯曲性和强度。相反,零碳天地竹亭则提出一种能够放大其结构潜能的设计。
竹亭的几何形状複杂,每枝竹竿有独特的形态、尺寸和结构性质,而且传统竹棚都是在没有图则下,利用专业直觉去建造,种种都令竹亭成为建筑师在设计控制上的大挑战。就此,团队研发了结合精确数字化设计系统和自然资源的方法,来应对这些未知数。


零碳天地竹亭未来将用作提倡绿色生活的展览、表演及活动的场地,它创新和可持续发展的建筑概念将影响公众和建筑设计界,以及广东传统搭棚工艺的未来发展。

Glowing bamboo pavilion promotes ecological design in Hong Kong


A glowing pavilion made from 473 bamboo poles was awarded Small Project of the Year in the 2016 World Architecture Festival awards. Designed by Chinese University of Hong Kong’s School of Architecture, the ZCB Bamboo Pavilion was built in the summer of 2015. The four-story-tall bamboo gridshell structure marries computational design and sustainable building materials to create a beautiful public space that promotes innovative and ecological design to the public.


The approximately 350-square-meter ZCB Bamboo Pavilion was built using Cantonese bamboo scaffolding techniques and it’s made from 475 large bamboo poles bent onsite and hand-tied together with metal wire. The pavilion sits in Kowloon Bay adjacent to the Zero Carbon Building (ZBC), a three-story plus-energy office building constructed in 2012 and topped with solar panels. In contrast to the ZBC’s square edges, the bamboo pavilion is curvaceous with a large diagrid shell structure that folds down into three hollow columns atop concrete footings.


The geometrically complex structure is lightweight and made with digital form-finding and real-time physics simulation tools that mitigate inconsistencies in the bamboo. A tailor-made white tensile fabric is stretched over the structure and its transparent quality creates a glowing effect when the pavilion is lit from the inside. The pavilion has a seating capacity of 200 people.


“Bamboo is a widely available, environmentally friendly material that grows abundantly and at remarkably high speeds in the Asia-Pacific region, Africa and the Americas,” says a statement on the Chinese University of Hong Kong School of Architecture website. “It is an excellent renewable natural resource which captures CO₂ and converts it into oxygen. It is strong, light and easy to process and transport. In Hong Kong, bamboo mostly appears in temporary theatres, scaffolding, or structures for religious festivals. Globally, it is usually applied as a surrogate for wood or steel, rather than in ways that utilise the material’s unique bending properties and strength. In contrast, the ZCB Bamboo Pavilion presents an alternative architectural application that maximises these latent material properties.”
