"Eye of the Xiangjiang River"

"New technologies are pushing the boundaries of traditional architecture, transforming the production of architecture and ultimately creating a new spatial consensus - the architecture of the future does not have to be 'frozen' music, but can also be a scene of activity."

"Eye of the Xiangjiang River"

Zhu Peidong, co-founder and lead architect of line+ Architects, led the team and joined hands with Dajie Intelligent Building to develop and land the first dynamic building in China - Changsha "Eye of Xiangjiang River". The project is an attempt to integrate multiple disciplines and adapt to dynamic changes, explore the extension of new technologies to the boundaries of architecture, and also provide new possibilities for the future use of multiple Spaces.

Respond to site conditions and explore technical boundaries

-- A new attempt at space production

"Eye of the Xiangjiang River" is located by the Xiangjiang River in Changsha. As an urban meeting room, it has the dual attributes of city view and regional landmark. As the site is restricted by vegetation along the river bank, it needs to be high enough to meet the two demands of viewing and landmark. However, if blindly raised, there is also a problem of blocking the line of sight of the surrounding buildings and damaging the commercial value of the riverview community. On the other hand, the interior space needs to adapt to the owners' specific requirements for privacy and openness by changing the scene in different occasions. A series of seemingly contradictory constraints, after combing through the breakthrough incision, all point to dynamic and variable scene demands.

The changes of The Times increase the uncertainty of space use, the one-way path of "environment-demand-space-technology" is broken through, and dynamic architecture may become a breakthrough. This project refines the internal and external demands, aiming at the dynamic adjustment of space elevation and the change of transparency and privacy of the skin, flexibly responds to the surrounding environment and space needs by means of the main space elevation and the opening and closing of the outer skin, and realizes the multi-dimensional integration of architectural structure, landscape interface and space experience.

In recent years, new technologies have caused transformative progress in many industries, but there are still few breakthroughs in the field of architecture, and some existing attempts are still limited to the local variable or opening of the outer skin of the building curtain wall, or focus on the extension and change of local indoor space walls or facilities. However, we believe that with the innovation of technology and the exploration of design, the architecture of the future will no longer be just a static display, but a dynamic organic space that can actively respond to environmental changes and meet the diverse needs of human beings.

Blooming attitude

-- Dynamic and variable spatial form

▼ This dynamic effect is accelerated mode, with a single rise/fall time of about 35 seconds

"Eye of the Xiangjiang River"

The overall concept of the building, that is, through the rise and fall of the main space, corresponds to the two activities of viewing/talking and the two architectural forms of display/concealing. At the single level, it is an integrated responsive system. Through the design idea of industrial installation, we first confirm that the whole building will be composed of the main space and the movable mechanical device, and change the connection relationship between the main space and the different floors of the east building according to the vertical displacement, so as to complete the switching of the two kinds of flow lines.

Under the two dynamic instructions of "open display" and "close and close", the sightseeing hall is lifted upward from the corridor to the roof layer, and the opening and closing surface can be expanded outwards, forming a transparent viewing field facing the Xiang River inside; On the contrary, the opening and closing surfaces can be closed to form a private space as the sightseeing hall descends. The overall shape is like the dynamic process of blooming flowers, and the spatial form of "The Eye of Xiangjiang River" has also begun to take shape.

In the form deepening stage, we hope to seek universally recognizable form images in the path of modular design and architectural installation of standardized components, so as to strengthen the resonance and interaction with the urban public. The opening and closing outer skin can be divided into nine pieces within the operable range, and the combination of four outer pieces (7m*5m) + five inner layers (6m*6m) is optimized according to the coincidence degree of "petal" and opening and closing Angle, and is modified into a rounded hexagon, with low transparency ETFE film as the main material.

Technology combination

-- Load systems and mechanical technology

The complex loading system and reliable mechanical technology ensure the stability and dynamic effect of the building.

"Eye of the Xiangjiang River"

Each petal in the opening and closing skin system is connected to the bottom hydraulic rod by a hyperbolic steel frame, and the arrangement of split-layer interpenetration achieves orderly opening and closing. The dynamic effect of the skin is realized by the intelligent linkage "motor + reducer + giant rotary disk" system. In different use scenarios, through the program setting of Angle and speed, the open state of different levels of petals can be realized, so as to switch the use scenario of the building, and dynamically respond to the viewing value needs of the surrounding office and residential units under construction, so as to avoid blocking their visual corridors for a long time.

Interactive intelligence

- Interactive digital design and intelligent construction

In the practice of "Xiangjiang Eye", the multi-disciplinary knowledge interaction has transformed the one-way path of traditional construction "demand-design-drawing - construction" into an interactive way of spiraling forward.

In the stage of design deepening and production construction, line+ cooperates with Dajie Intelligent Manufacturing to realize the digital design optimization of the whole process, the production of smart factory components, and the assembly construction and installation, so that the whole life cycle of the project from design to implementation is efficient, accurate and controllable.

Conclusion

"Architecture is frozen music". The traditional construction method and supporting structure of architecture determine its static properties. "Xiangjiang Eye" creates a new experiential urban public space with the design and construction path of industrial installations. With the support of new technologies such as digital model, simulation technology and intelligent construction, it tries to break through the dimensional limitations of traditional architecture and create a feasible sample for the overall dynamic architecture - space is no longer frozen, it can also be fluid and changing.
