概念与形态的创新：该项目最引人注目的亮点在于其设计理念的创新性和对儿童主题的深刻诠释。设计师长山由子以儿童的“不确定性”和“发展性”为核心，颠覆了传统建筑的几何秩序，采用有机、流动的建筑形态，象征着儿童未定型的未来。初始手绘草图的抽象与不确定，直接促成了建筑整体“细胞状单元聚集”的有机结构，这种设计思路摆脱了迪拜世博会日本馆的几何系统化，展现了自由、动态的建筑语言，为世博会展馆设计带来了耳目一新的视觉体验。这种对主题的深刻理解和大胆的形态探索，是项目最显著的创新之处。

结构与材料的巧妙结合：项目的精髓体现在结构设计和材料运用的巧妙结合。设计师没有拘泥于传统建筑的结构方式，而是以“720度循环”为主题，采用了三维弯曲钢管图案，类似蝴蝶翅膀，并通过特殊的3D成型机械来实现。这种结构设计在视觉上极具表现力，同时也带来了技术上的挑战。同时，建筑师将风洞试验与结构分析相结合，保证了结构的稳定性。更值得称道的是，项目大量运用了松下集团工厂的回收材料，如人造大理石、棱镜片等，用于室内装修和照明设备。这种材料的循环利用，以及蝴蝶图案所象征的循环主题，共同构建了一个可持续的建筑理念。

动态立面与可持续理念的融合：该项目的另一亮点是其动态立面的设计，以及对可持续发展理念的深入践行。蝴蝶图案上覆盖的透明硬纱膜，对海风的响应，使其在风中不断运动，营造出一种动态的、皮肤般的表面，极大地增强了建筑的视觉吸引力。同时，硬纱颜色的变化，也为建筑增添了丰富的层次感。更重要的是，项目在世博会后，还获得了搬迁和再利用的机会，这体现了设计师对建筑生命周期的深刻思考。这种设计理念，不仅符合现代建筑的可持续发展趋势，也为世博会展馆提供了可复制的范例，具有极高的社会价值和文化意义。

建筑师提供的文字描述。松下集团展馆，NOMO之地，专为儿童设计。通过有机和流动的建筑形式，展馆试图反映儿童的形象，他们的未来仍然是不确定的，并且不断发展。2020年迪拜世博会的日本馆采用了基于几何的高度系统化结构，而松下馆则探索了一种自由和有机的结构方法。
Text description provided by the architects. The Panasonic Group Pavilion, The Land of NOMO, is designed for children. Through an organic and fluid architectural form, the pavilion seeks to reflect the image of children, whose futures remain unfixed and ever-evolving. While the Japan Pavilion at Expo 2020 Dubai featured a highly systemized structure based on geometry, the Panasonic Pavilion explores a structural approach that appears free-form and organic.

First drawing by Yuko Nagayama

长山由子最初的素描就像一幅孩子的画，模棱两可，抽象。它象征着儿童是尚未形成、不断变化和成长的存在。因此，建筑形式被认为是一种有机结构，由聚集在一起的小细胞状单元组成。
The initial sketch by Yuko Nagayama resembled a child's drawing, ambiguous and abstract. It symbolized children as beings that have yet to take form, continuously changing and growing. Thus, the architectural form was conceived as an organic structure composed of small, cell-like units aggregating into a whole.

该结构以“720度循环”为主题，由蝴蝶翅膀等三维弯曲钢管图案组成。这些管道是使用专门的3D成型机械成型的。根据结构要求，选择了直径为38.1mm、45.0mm和48.6mm的三种钢管。总共1404个具有六种不同形状的图案垂直堆叠成20层，形成拱门。通过组装四种不同半径的各种拱门，创造了一个动态和不规则的立面。
Based on the theme "720-Degree Circulation," the structure is composed of an accumulation of three-dimensionally bent steel pipe motifs like butterfly wings. These pipes were shaped using specialized 3D-forming machinery. Three types of steel pipes, 38.1 mm, 45.0 mm, and 48.6 mm in diameter, were selected based on structural requirements. A total of 1,404 motifs with six different shapes were vertically stacked in 20 layers to form arches. By assembling various arches with four different radii, a dynamic and irregular façade was created.

Facade Geometry

为了确保结构稳定性，特别是在临界风荷载下，风洞试验与结构分析相结合。目标是确定一种结构高效、视觉表现力强的形式。每个蝴蝶图案都配有一个溅射涂层的透明硬纱膜，它以不断的运动来响应海风。透明硬纱的颜色会根据观察角度而变化，从而形成一个动态的、类似皮肤的表面，包裹着整个结构。
To ensure structural stability, particularly against critical wind loads, wind tunnel testing was conducted in conjunction with structural analysis. The goal was to identify a form that was both structurally efficient and visually expressive. Each butterfly motif is fitted with a sputter-coated organza membrane, which responds to the ocean breeze with constant motion. The color of the organza shifts depending on the viewing angle, creating a dynamic, skin-like surface that envelops the entire structure.

此外，展馆还采用了来自松下集团自己工厂的升级回收材料。厨房系统中使用的人造大理石和电视中使用的棱镜片等边角料和废料已被重新用于室内装修和照明设备，特别是在接待区。这些可回收的元素，以及蝴蝶形状所体现的循环主题，共同构成了一个象征着人类作为一个不断循环的世界的一部分的立面。与妇女馆一样，这座建筑在世博会结束后也获得了一个搬迁地点，现在正在进入下一个再利用周期。
Additionally, the pavilion incorporates upcycled materials sourced from Panasonic Group's own factories. Off-cuts and waste materials such as artificial marble used in kitchen systems and prism sheets used in televisions have been repurposed for interior finishes and lighting fixtures, particularly in the reception areas. These recycled elements, along with the cyclical motifs embodied by the butterfly forms, contribute to a façade that symbolizes humanity's role as part of a continuously circulating world. Like the Women's Pavilion, this building has also secured a relocation site following the conclusion of the Expo and is now moving forward into its next cycle of reuse.
