The first impression given by Xiasha Higher Education Park is its crisscross traffic and water network. Hurrying along the roads, people might feel a lack of vitality at the street boundaries due to the checkerboard layout of the city. Under the historical background of classical rational planning, it is urgent to explore the direction of breaking through the inherent paradigm to build an educational building facing both the campus and the city.
The rationality of architectural modeling, the complexity of sharing function and the flexibility of multi-dimensional communication are the difficulties in the design of this "community-based" teaching laboratory building. In the process of scrutinizing the architectural scheme, the trio constantly collides and runs in, and finally interweave with the city texture, injecting abundant vitality into the region and redefining the boundary between the campus and the city.
Interlude between city and campus space
The construction site is located in the southeast corner of Zhejiang University of Water Resources and Electric Power, with its southeast side facing with water. Initially, we tried to intervene in the overall layout of the city and campus, in an attempt to echo the teaching group of the experimental training building with the urban planning and the main axis of the campus, sort out the texture of the site, and reshape the spatial level of the campus. With the change of campus axes, three axes, namely, main axis, building group axis and group axis, were formed. Streets and squares on both sides of the axes become the activity places generated by the three axes.
The site is at the south end of the group axis. As an important node of the axis, the design adopts the form of semi-enclosed courtyard to close at the end of the axis. Based on the existing site conditions and the main direction of people flow, the building group defines the reality and virtuality in the limited site space with an intensive semi-enclosed structure.
The semi-enclosed structure and the existing northwest teaching building constitute a typical courtyard space. While providing a complete venue for social activities, the dialogue with the existing teaching buildings also perfects the original broken figure-ground relation. This relation is nested in a larger figure-ground of the city. The close jigsaw puzzle relationship between the two further enriches the form of urban space, making it different from the serious impression brought by chessboard layout and have a more dynamic rhythm.
Considering the repetitiveness and rhythm of the existing urban boundaries, the facade design needs to combine the pure rationality with the unique architectural character.
In the design, the enclosed structure is regarded as a kind of "prototype" of courtyard space, and the building group deduces and combines it, and evolves four types of secondary structures: "L", "U", "一" and "回". Multi-type courtyard combination builds different enclosure attributes for different colleges, and breaks the single space form of copying ordinary teaching buildings. Street facades composed of different types of structures contain rational genes, presenting a unique poetic quality of space compared with the surrounding buildings.
Campus boundaries under the vision of sharing and exchange
There are seven colleges of different disciplines in the Second Experimental Training Building. How to realize interdisciplinary academic exchange is the difficulty that this building needs to face directly.
The secondary structures take the discipline function as the link and the overall order conforms to the figure-ground texture of the campus space. Combining the north-south campus layout and road direction, it takes the internal courtyard as the core, and puts in the contrast structure that stimulates vitality to create a rational and lively scientific research complex. As variants of "prototype", the secondary structures generate different connotations in a specific context. The combination of three basic architectural terms - point, line and plane, integrates space enclosure, behavior continuity and vitality stimulation, which echo each other.
Plane connection is one way to achieve the vision of sharing and exchange, while vertical connection is often overlooked.
The mutual occlusion of secondary structures provides diversified space margin for vertical communication. The seven colleges are distributed independently of each other, each occupying a corner. The design lifts all kinds of structures as a whole, weakening the vertical constriction while creating a two-storey transparent sharing platform. In the design, the main college entrances are set on the two-storey platform, featuring good transparency, convenience and accessibility, which can increase the frequency of sharing and exchange among disciplines. At the same time, in a single building, an indoor atrium is set up to create a communication space.
The establishment of a vertical sharing platform also represents the various possibilities of conceptual courtyard space in contemporary architecture, and the attempt of horizontal and vertical multiple dimensions is also a far-reaching reflection on the relationship between architecture and society.
Urban boundaries with both rhythm and order
Architecture should pursue the overall concept of homogeneity from design concept to facade texture and then to architectural details. The secondary structures endow the internal commonness among the elements of the facade. In order to build a harmonious order and beauty of rhythm, the facade texture structure should be an important influence factor to be considered.
The facade continues the vertical elements of the original campus building facade, and adopts the design of vertical metal grilles combined with perforated aluminum plates. The vertical metal grille form a sense of rhythm, which is neat and full of changes. The pattern of perforated aluminum plates originates from the reconstruction of campus emblem, which endows the building with a unique symbol.
On the basis of preserving the integrity of the facade, the rhythmic weaving makes the sunlight diffuse and melt on its surface, and the texture of the grilles changes with the light. The light and shadow brought by the movement of the sun flow with delicate water wave texture, which is dynamic and brilliant, reflecting the change of time and the vitality of the campus.
The metal grilles shield direct sunlight and make the light of the experimental room soft. Perforated aluminum plates play a role in shielding the external units of air conditioners, being both aesthetic and practical. The window-wall system of the building itself saves cost, economical and practical. In addition, the metal grille surface can make climbing plants cling to it, adding greenery to the campus space. Surface texture and structural details highlight the thinking of sustainable design, forming a unique facade form.
In the mannered urban planning environment, the Second Experimental Training Building of Zhejiang University of Water Resources and Electric Power insists on rationality and unity without losing uniqueness and diversification, and excavates the potential of the site in order. All kinds of forms are not isolated or independent, but interweave and collide with each other in a specific context. With the rationality and romance of architectural modeling, the complexity and diversity of sharing function, and the flexibility of multi-dimensional communication space, this project depicts multi-level ideas and composes a long interlude between the campus and the city.
