［フォーラム後記｜Forum Epilogue］25［ファシリテーター：水出喜太郎］What is environmentally regenerative architecture? To me, it is architecture for “us,” for humanity. Architecture is constantly being created and involves the efforts of many different individ-uals. I believe the world would benefit immensely if we thought of architecture not only as “ours” (we architects), but also of the society to which we all belong.─Generative To embrace the notion of “regenerative,” we must first under-stand the concept of “generative,” the concept at the heart of artificial intelligence (AI). Over the coming decade, generative AI is expected to advance to a level of intelligence 10 times that of humans. In light of this, how do human beings have to evolve to survive? For the design of the Jellyfish Pavilion for Expo 2025 Osaka, Kansai, a group of us came together to ponder and discuss the theme of “life.” If we understand humans to be the cause of increasing environmen-tal degradation, how should we proceed? Jellyfish lack a brain, seeming to represent organisms that come and go between the worlds of flora and fauna, and according to one theory, their numbers increase as environmental pollution worsens. Jellyfish flow passively along with their environment while at the same exerting an effect on it; thus, we adopted the jellyfish concept for the pavilion. We used wild plants commonly found in Osaka for the landscaping and employed an algorithm based on the growth of slime mold. In short, we tried to create an unstructured world. The pavilion was designed with consideration for the next phase of its life, as every component will be reused after the expo. In this way, the architecture is based on circular economy principles.─AmbiguityThe environment is certainly a key theme when it comes to regen-erative design, but I think regenerative design is also closely tied to human relations. At the Arisawa Innovation Center, we make use of snow. We place snow on a roof and as it melts, we plan to store it underground where it will be used as a heat source. The idea for this design was generated through various workshops and discus-sions with Nikken Sekkei. The client and designers brainstormed at the workshops, and with the same goal in mind, their positions became inter-mingled, and both relationships and the organizational struc-ture became blurred and indistinct. Strangely enough, ambigu-ity can give rise to concepts, ideas, and designs that are com-pletely new and fresh, and this kind of ambiguity is important in regenerative design. When the design process itself can be pursued together with the client and both parties take an inter-est in it, the architecture becomes something that everyone involved considers their own. Thus, it will continue to remain productive even after it leaves the designer’s hands. street arcades under the extended eaves of individual building; these allow passage before the shops even when snow cover is heavy. Arcades are normally public spaces, but theaves are built by the landowners, whose buildings are set back from the street. This wisdom of regions with heavy snowfall—the idea that one’s own house can be aligned with the needs of the com-munity—is a way of designing architecture for everyone. In Takada, Niigata, where the project is located, there are Moving beyond the objective of sustainability, we are focusing on styles of regenerative design. The growing dangers associated with climate change have led to requirements that companies disclose climate-related financial information; at the same time, biodiversity and human capital management initiatives have become more important in investment decisions. We are currently experiencing a significant shift in some of our core values. To us, this presents an opportunity. Environmental protection and CO2 reduction were once seen as costs; now, in the form of accountability for investment, they are part and parcel of actual economic activities and the design of the built environment. Concepts such as coexistence with nature, wellness, resilience, and attachment—perhaps often associated with Asian cultures—have become entrenched in economic activities, and the field of design is steadily expanding to encompass these ideas. comfortable and healthy environments that incorporate the natural world and use minimal resources and energy, and which will be used and cherished well into the future. I believe this positive cycle of regeneration will be fundamental to our burgeoning new society. We would like to play a role in supporting these positive changes through architecture and engineering. 均衡を保ちながら持続可能な社会を目指す考え方である「サステナビリティ」のその先へ、ということで、私たちはリジェネラティブデザインというスタイルに注目しています。気候変動リスクの高まりから、企業は気候関連財務情報の開示を求められ、一方で生物多様性や人的資本経営への取組みが投資判断で重視されるようになりました。このように現代は価値観の軸が大きく変わる時代です。私たちはこれをチャンスと捉えています。環境配慮や CO2 削減という、これまでコストと捉えられていたアクションが、投資に対する説明責任という形で実際の経済活動、建築環境のデザインにぐっと近づいてきました。　アジア的なと言いますか、自然との共生、ウェルネス、レジリエンス、愛着といったキーワードが経済活動にも定着し、そうした領域へデザインのフィールドは確実に広がりつつあります。　自然を取り入れて、なるべく少ない資源とエネルギーで快適で健康な建築環境をつくる、そしてそれらが愛着をもって永く使われる、これがリジェネラティブデザインだと感じています。新しい社会ではこのポジティブな循環再生がカギになると考えています。それを支える建築とエンジニアリングでありたいと思います。 I feel that regenerative design is about creating [Facilitator: Kitaro Mizuide]
