该展馆由大阪府与大阪市共同打造，亮相于2025年日本大阪关西世博会。结合“重生”主题，展馆旨在通过设计新一代建筑、与环境共生建筑来体现主办城市的愿景，为实现可持续发展目标、建设有机社会贡献力量。设计灵感源自大阪作为“水之城”的历史文化——这是一座因木材与水而繁荣的城市。展馆对这些核心元素进行了创新性诠释与呈现，打造了新的建筑地标，向世界展示大阪的魅力与发展。
Text description provided by the architects. This pavilion is presented by Osaka Prefecture and Osaka City at the Expo2025 Osaka, Kansai, Japan. Under the main theme of "REBORN," it aims to embody the host city's vision by creating a next-generation, environmentally symbiotic architecture that contributes to the realization of SDGs and a decarbonized society. Inspired by the history and culture of "Water City Osaka," which has thrived on wood and water, the pavilion reinterprets these elements to create a new architectural landmark that showcases Osaka's charm and growth to the world.
独特的薄膜屋顶，形态各异的屋顶设计，象征了大阪的多样性。循环水流经屋顶形成“水面纱”，汇入下方水池。池水经过滤后，在可持续系统中循环利用。内部和外部饰面均使用大阪府的当地柏木。中庭沐浴在柔和、斑驳的光线中，营造出宁静温馨的空间，原始木材的色泽和独特气息，使置身其中的参观者倍感舒适和放松。
The unique membrane roof, with no two shapes alike, represents the persity of Osaka. "Water Veil" is formed as recycled water flows over the roof, cascading into a water basin below, where it is filtered and recirculated in a sustainable system. Locally sourced cypress from Osaka Prefecture is used for the interior and exterior finishes. The central atrium is bathed in soft, dappled light, creating a serene and inviting space filled with the warmth and fragrance of wood—a true symbol of relaxation and comfort.
中庭和展览空间采用椭圆形平面设计，有机地重叠在一起。这些椭圆通过缓坡连接，形成流畅的参观动线，构成包容性空间布局，确保所有参观者获得一致的参观体验。中庭的木质螺旋柱灵感来自 DNA 结构，象征性地支撑着多样化的屋顶形态。
The atrium and exhibition spaces are designed with elliptical floor plans that organically overlap. These ellipses are continuously connected by gentle slopes, creating a seamless circulation route that allows all visitors to experience the same exhibition path—an inclusive spatial layout. The wooden helical column in the atrium, inspired by DNA, symbolically supports the perse roof forms.
木制螺旋柱及所有内外部饰面均使用来自大阪府的当地木材。为了有效地过滤和漫射屋顶自然光，建筑师采用了一种新材料，该材料是通过从回收纸浆中捻出纱线并将其缝制成类似纺织品的织物。此外，轻巧灵活的新一代过氧化物太阳能电池以悬挂方式呈现，为太阳能的利用提供了一种新颖的表现形式。
The wooden helical column and all interior and exterior finishes use locally sourced timber from Osaka Prefecture. To appropriately filter and diffuse natural light from the roof, we used a new material, made by twisting yarn from recycled pulp and sewing it into a textile-like fabric. In addition, lightweight and flexible next-generation perovskite solar cells are suspended in banner form, presenting a new expression of solar energy use.
为了实现复杂的设计造型，建筑师在设计过程中充分运用了计算机技术。膜屋顶的每个曲面都是由不同半径的球体修剪而成的球形片段组成。这种球形几何形状，便于透明膜的安装和桁架结构的有效布置。开发 3D 模型用于模拟“水面纱”的效果和环境情况。
To realize the complex forms, we embraced new design methods utilizing computational design. Each curved surface of the membrane roof is composed of spherical segments generated by trimming spheres of various radii. By using spherical geometry, we made it easier to fit the transparent membrane and arrange the truss structure efficiently. The 3D model we developed was used for simulating "Water Veil" and environmental conditions.
支撑膜屋顶的木制螺旋柱为受 DNA 启发的双螺旋形式。该项目面临的主要挑战在于如何使用木材构建复杂的曲面形式。为了平衡美学和成本效益，项目最大限度地减少了弯曲木材的使用，主要依靠扁平的木质构件来实现双螺旋结构。
The wooden helical columns that support the membrane roof feature a double-helix form inspired by DNA. One of the major challenges was constructing these complex curved surfaces using wood. To balance aesthetics and cost efficiency, we minimized the use of bent wood and realized the double-helix structure primarily with flat wooden elements.
大阪凭借得天独厚的河流和海洋资源，同时使用来自日本各地的木材进行建设，已发展成为一座魅力之城，并在多元特性的融合中繁荣发展。大阪医疗保健馆是进步的象征，完美诠释了“再生”的主题，描绘了一个生命、可持续性和创新在此共同闪耀的未来。
Blessed with rivers and seas, and built using timber from all over Japan, Osaka has developed to be an attractive city and flourished through the amalgamation of many perse identities. Osaka Healthcare Pavilion stands as a symbol of progress, embodying the theme of "REBORN." A future where life, sustainability, and innovation shine together.
