熊猫塔是 UDG. Atelier Alpha （联创设计集团 零号工作室）为成都大熊猫繁育研究基地扩建区打造的集观景、展示、游览为一体的文化新地标，同时也是将自然与科技结合的设计实践之作。

The Panda Tower is designed by UDG Atelier Alpha for the new campus of the Chengdu Research Base of Giant Panda Breeding. It is a new cultural landmark that combines observation, exhibition, and sight-seeing. In addition, it is a work of practice that celebrates the combination of nature and technology.

UDG . 零号工作室于2019年10月参与了该项目的全球方案征集，并于2020年4月确认中标。方案公布以来，熊猫塔因为其独特的造型而备受各界关注，项目已于2021年底竣工，熊猫基地新园区也于2022年元旦正式开园。

UDG Atelier Alpha participated in the global call for design proposals in October 2019 and won the competition in April 2020. Since the design was published, the Panda Tower has attracted the attention of various walks of life. The project was completed at the end of 2021 and the new campus of the Giant Panda Breeding Base officially opened on 1st January, 2022.

熊猫塔建筑形态灵感来源于竹笋，既是熊猫最爱的食物，同时也是川菜中最具人气的食材之一，广泛分布在川渝地区。竹笋下大上小自然收分的几何特质很适合作为塔体稳固的结构形式。

The inspiration of the Panda Tower comes from the bamboo shoots. Widely distributed in the Sichuan-Chongqing region, not only are the bamboo shoots the favorite food of the Giant Panda, they are also considered one of the most popular food ingredients in the Sichuan cuisine.

塔主体部分一共有11层，每层朝向园区核心景观区的方位都有一个观景大露台，没有幕墙格栅的覆盖，暴露出楼板和斜撑结构。

The main structure of the tower has 11 stories. There is a spacious viewing platform looking towards the central viewing area of the conservation park on each story. Without curtain walls nor gratings, the floor slabs and the buttresses are honestly exposed.

游客可以从熊猫塔正面的大台阶登上基座平台，也可以从盘旋在土丘景观之上的小路达到熊猫塔的主体部分。

The tourists can access the platform of the podium from the grand stairs in front of the tower. Alternatively, they can reach the main structure of the tower from the spiral walkway that goes along the landscape.

塔主体各层楼板由弧形结构单元组合而成，意向取自成都的市花-芙蓉花瓣。花瓣楼板数量，由下至上呈等差数列逐层递减。中庭仰视呈现出具有数学感的空间美学效果。

The main body of the tower is composed of the floor slabs and the arced structure units. The inspiration is the pedals of the hibiscus flower, the city flower of Chengdu. The number of the pedal slabs decreases in an arithmetic progression from the bottom of the tower to the top. Viewed from the central courtyard, the space demonstrated the beauty of mathematics.

熊猫基地不仅是保护大熊猫繁育和研究的机构，同时也是成都这座公园城市开放给市民的近距离与熊猫交流的主题公园。熊猫塔在这座主题公园里的定位，不仅是供游客登高远眺的平台，更是代表这一方水土和文化的自然图腾。

Not only is the Giant Panda Breeding Base an organization that protects and studies the Giant Panda, it is but also a theme park in the Garden City of Chengdu that offers the visitors opportunities to interact with the pandas from a close distance. The Panda Tower provides the visitors with a lifted viewing platform. What’s more, it represents the natural totem of the culture of the region.

熊猫塔塔冠的幕墙部分被赋予了一套动力机械系统，在特定时刻（熊猫宝宝出生，出国英雄熊猫退伍回归，重要节假日等等）幕墙单元可以按照程序设定的角度和速度依次开启，就像自然界的“春笋发芽”一样，以对生态更友好能源更清洁的方式向游客传达信息，产生互动。

The top of the curtain wall system of the Panda Tower has a mechanical system that opens the façade units according to programmed angles and speed on special days, such as the birth of new Giant Panda babies, the return of Giant Panda from oversea facilities, and important holidays and festivals. The opening of the façade resembles the sprouting of the bamboo shoot. The interaction with the visitors is eco-friendly and uses clean energy.

熊猫塔整体设计采用全程序控制，所有建筑的构建单元都在程序中通过添加约束条件关联起来。几何约束控制空间形态，力学约束控制结构尺寸，动力学约束控制可开启装置。这些严谨的数学公式化的约束条件，既是熊猫塔最重要的设计基因，同时也是所呈现空间效果背后的美学基础。

The Pada Tower is completely program-controlled. All the architectural elements are correlated through the constraints in the grasshopper definition. The geometric constraints define the space, the mechanical constraints limit the structural components, and the dynamics controls the retractable device. This rigorous system of mathematical constraints is the most important design gene of the project, as well as the base of aesthetics of the resulted space.
