Hybrid是2023年杭州亚运公园中的核心建筑，可容纳5000人。该体育馆位于公园入口南端，可以通过两座弯曲的连桥进入。这座35000平方米的建筑旨在吸引和创造新的社会文化活动，因而被构想为一个“混合体”（Hybrid）。设计目的是将体育赛事与音乐厅和活动空间结合起来，以备在亚运会结束后用作城市的活动场所。

This 5,000-seat centerpiece for the Hangzhou Asian Games 2023 Park is located at the south end of the park entrance and accessed via two curved bridges. The 35,000m2 structure is designed to function as attractor and generator of new socio-cultural activities and hence was proposed as Hybrid; merging sports events with a concert hall / event space for Hangzhou after the games.

Hybrid的设计灵感源于杭州当地的文化传统，以“琮”这种古代玉器（方柱形，内里是圆形）为意象，体现了“混合”而非单一的特征。Archi-Tectonics事务所通过参数化设计研究创造出一种混合式的分类方法，即通过两个相交的椭圆形构建重叠的空间，从而实现建筑内部空间及其与外部的流畅连接。最终得到的建筑是一组具有高度适应性的体量，它可以在运动会结束后无缝转变为活动空间。

The Hybrid embodies the heritage of the region, adapting the intersecting geometry of the Cong—an ancient Jade-stone artifact in the shape of a square tube with a circular bore— a hybrid building, rather than a singular stadium, that maximizes legacy adaptability and embraces the spirit of Hangzhou. Archi-Tectonics’ parametric design study into the creation of a hybrid taxonomy, two intersecting ellipses with overlapping spaces that allow for fluid connections within the interiors and connect to the exterior. The result is a highly adaptable set of volumes that can seamlessly convert to event space after the games.

混合的几何构造：摇摆的圆盘 Hybrid Geometry: Wobbly discs

Hybrid的几何构造经过反复推敲，最终呈现为独特的非对称形。长圆形碗内的坐席融合了竞技场和露天剧场的座位设计，从而可以在需要时，将体育比赛的中央观看布局调整为演出模式下以舞台为中心的非对称布局。双曲面的内碗完全由竹子包裹，上方安装有嵌入式的照明和天窗，将技术产生的形式与本土材料相融合，创造出温暖宜人的环境。

The Hybrid’s geometry was refined through multiple iterations and produced the distinctive asymmetric shape. The seating for the oblong bowl merges arena and amphitheater seating schemes. This makes it possible to adapt the central viewing layout preferred for sporting events into an asymmetric, stage-centered configuration for performances. The double-curved inner bowl is entirely clad in bamboo with recessed lighting and a skylight above, blending technologically generated forms with vernacular materials that offer a warm and inviting environment.

两个圆盘状的体量在相互交叠时形成了空间上的异变，成为具有标志性的瞬间。碗的长圆形部分设有贵宾休息室。坡道和楼梯创造出水平和垂直方向上的层叠关联，使观众从热闹的城市环境过渡至冷静、内向的赛场空间。坡道可以折叠或展开，绕着碗体延伸至未来的剧场休息室，后者的户外屋顶平台可以俯瞰到如今已重焕生机的湿地与生态公园景观。

As they slip past each other, the disc volumes create spatial anomalies that become signature moments. The more oblong section of the bowl hosts VIP seating lounges. The ramps and stairs that usher visitors to the seats create layers of horizontal and vertical interconnection, transitioning from the lively city to the calm, inward-looking space of the arena. Ramps fold up and around the bowl to get to the future theater lounge with an outdoor roof deck overlooking the re-invigorated wetlands and eco-park landscape.

弦支穹顶：无柱的混合型室内空间、自然采光与通风 Suspendome Roof: Column-Free Hybrid Interior Spaces, Natural Light and Ventilation

Archi-Tectonics事务所在竞标阶段便主动联合Thornton Tomasetti公司为项目提出最具创新性的结构解决方案。大跨度的弦支穹顶（或称超级穹顶）使完全无柱的大厅空间成为可能，同时加强了建筑的适应性和混合特征。屋顶位于内碗结构上，悬挑于大厅上方，并支撑着建筑的外壳——由钢和玻璃构成的宏伟斜交网格表皮。

Archi-Tectonics took the initiative already in the competition phase to engage Thornton Tomasetti, to come up with the most innovative structural solutions. A long-span Suspendome or Superdome roof makes it possible for the lobby spaces to be entirely column-free, reinforcing the adaptability and hybrid nature of the building. The roof sits on the inner bowl and cantilevers out over the lobby to support the outer shell, a spectacular steel and glass diagrid skin.

内碗坐席下方的集成冷却系统可以为观众降温，并最大程度地减少空气流动（乒乓竞技场馆的要求），并显著地减少制冷和供暖的需求。气温调节只在观众席周围的区域实施，而非针对整个气体流量。

An integrated under-seat cooling system for the inner bowl cools the viewers, while minimizing air movement—a requirement for competitive table tennis venues—while significantly reducing the cooling and heating demand. Only the immediate area around the spectator seating is conditioned, rather than the entire air volume.

立面 – 玻璃斜交网格和黄铜面板 Facade—Glass Diagrid and Brass Panels

相交的椭圆形在外观上呈现为两种有纹理的表面：一种由黄铜面板覆盖，在经过精确校准后，覆盖了建筑的双曲面体量；另一种则是由平面玻璃覆盖的钢质斜交网格。由铝制的三角形单元组成的系统连接了平面状的玻璃与双曲斜交网格，这些“眼睑”还为立面赋予了一种鱼鳞般的闪亮外观，并提升了其动态感和纹理感。

The intersecting ellipses express themselves as textured facade surfaces—one clad in brass shingles carefully calibrated to cover the doubly curved volume and the other a steel diagrid clad in planar glass. A system of small aluminum triangles negotiates the planar glass back to the double curved diagrid. The ‘eyelids’ also give the facade its shimmering fish scale-like appearance and lend it a sense of movement and texture.

玻璃单元从黄铜表皮中切过，形成透明的区域，使日光可以进入室内。立面与大跨度的弦支穹顶一起，为穿行在建筑中的游客创造出明亮、动感且开阔的体验。在玻璃围合的宽敞大堂内，坡道和连桥包围着内部的碗体结构。

The glass sections bend and slice through the brass shingles, creating transparent areas where daylight can enter the interiors. Along with the long-span Suspendome roof structure, this creates a light-filled, dynamic and spacious experience for visitors as they move through the building. The glass encloses a sweeping lobby with ramps and bridges that wrap around the inner bowl.
