Paper Presentation at CDRF 2026 (Sydney) | AGB Employee Presents Research Findings at International Conference

From Wednesday, July 8, to Friday, July 10, 2026, at UNSW Sydney in Sydney, Australia, Hiroki Awaji of Asahi Building Wall Co., Ltd. (hereinafter “AGB”) presented a research paper on the circular manufacturing of free-form facades at the international conference “CDRF 2026 (International Conference on Computational Design and Robotic Fabrication)”.

CDRF is an international conference focusing on computational design, digital technology, robotics, and advanced manufacturing technologies in the field of architecture. This eighth edition, held under the theme “Circular Intelligence,” featured discussions among researchers and practitioners from around the world on the transition to a circular economy in the architecture and construction sectors through the use of digital technology.

The fabrication of free-form GRC facades presents challenges such as formwork waste generated by complex shapes and the environmental impact of the materials used. In this study, we propose a circular fabrication system that combines reusable, automatically controlled variable formwork with a composite material made from unfired clay and magnesia cement.

In this study, we fabricated double-curved panels using unfired earth with a full-scale, automatically controlled variable formwork system. Furthermore, we verified the effectiveness of the proposed manufacturing system by 3D scanning the completed panels to evaluate their geometric accuracy.

By combining the development of reusable adjustable formwork with the development of low-environmental-impact unfired clay-magnesia cement composite materials, we are presenting a new direction for reducing both manufacturing and environmental impacts in the production of free-form facades using digital technology.

Moving forward, AGB will continue to bridge the gap between practice and research as we work to create new possibilities in the fields of architecture and facades.
