Appreciation towards ICD (University of Stuttgart) + ITKE (University of Stuttgart) for providing the following description:

在复杂的生态、社会经济和社会文化危机的背景下，我们迫切地需要一种全新的设计、工程和施工方法去重塑建筑与建造的大环境。如今，我们的社会已经从能源丰富、且热衷于工业材料的时代，转向了能源稀缺、且倾向于采用天然材料的时代，因此，材料智能将成为建筑逻辑的代名词。

At the nexus of complex ecological, socioeconomic, and sociocultural crises, the built environment urgently requires a fundamentally new approach to design, engineering, and construction. As we shift from an era of energy abundance and industrial materials to one of energy scarcity and natural materials, material intelligence will become synonymous with construction logic.

HygroShell在2023年芝加哥建筑双年展上首次亮相，它诞生于上述时代范式转变的最前沿，利用以前不受欢迎的木材，以及其材料吸湿的特性创造出独特的形式和结构，探索了一种新的基于生物且灵感源于生物的建筑构成。

HygroShell, which makes its debut at the Chicago Architecture Biennial 2023, is at the forefront of this paradigm shift, harnessing the previously undesirable hygroscopic material properties of wood to create form and structure, exploring a new kind of bio-based and bio-inspired architecture.

HygroShell探索了一种首创的自构建木结构建筑系统，项目的成功预示着建筑中新材料文化的崛起。研究团队采用了新颖的计算方法来量化木材固有的形状变化特性，创造出一种全尺寸、长跨度、轻质外壳的结构，该结构由平面的木材在现场弯曲成型，实现了从设计到工程计算到制作搭建的一体化流程。结构中的每个组件都具有建筑、结构和动力学的特征，平面状态的木材于现场进行弯曲，并形成一种相互嵌套互锁的稳定几何状态。

HygroShell investigates a first-of-its-kind, self-constructing-timber building system, heralding new material cultures in architecture. Utilizing novel computational methods to access timber’s inherent shape-changing properties, HygroShell showcases the design, engineering, and production of a full-scale, long-spanning, lightweight shell made from flat-packed, components curved in situ. Each component contains architectural, structural, and kinetic characteristics embedded into its flat state, actuating on site to produce a curved, shingle-clad, interlocked geometry.

最终该结构以精致的弧形天篷的形式呈现出来，其跨度达10米，但结构厚度只有28毫米。与典型的结构类型不同，使用生物基材料的薄壳结构屋顶，采用了单曲线的设计，发掘了建筑结构在节约资源方面的新潜力。HygroShell利用木材的基本特性作为原位成形机制、结构驱动因素和设计基础，探索了一种面向未来的建筑的替代方法。通过这种对自然材料的计算量化，新一代设计师能够在材料和形式上实现更深层次的建筑整合，并在建筑中探索一种生态有效但又富有表现力的材料文化。

The result is a delicately arced canopy spanning 10 meters while only 28 millimeters thin. Diverging from typical structural typologies, the roof’s single-curved design unlocks new potentials for resource-saving, thin-shell construction with bio-based materials. HygroShell explores an alternative approach to future-proof architecture using the fundamental properties of timber as an in-situ shaping mechanism, structural driver, and design foundation. Through this computationally enabled understanding of natural materials, it is possible to achieve deeper architectural integration in both material and form, and to explore an ecologically effective, yet expressive material culture in architecture.

HygroShell是ITECH研究生项目的建筑师和工程师，以及来自斯图加特大学IntCDC（综合性计算设计和建造）的精英集群合作设计开发的研究性展亭，可谓是突出了跨学科和多样化研究和教育环境的重要性和潜力。

HygroShell was developed as a research pavilion within the context the ITECH Master’s program and the Cluster of Excellence Integrative Computational Design and Construction for Architecture (IntCDC), highlighting the importance and potentials of a cross-disciplinary and diverse research and educational environment.
