NOMURA Co.,Ltd. Ltd. exhibited a booth at "SC Business Fair 2024," the industry's largest event bringing together shopping center stakeholders. Held at Pacifico Yokohama displays Hall for three days from January 24th to 26th, 2024, Nomura Co., Ltd. not only exhibited a booth but also held a free seminar on the first day of the event. The theme of this year's booth was "Sustainable concept design as Envisioned by NOMURA Co.,Ltd." As part of our social good R&D activities, we are developing a "Sustainable concept design Manners Book" that realizes aesthetic appeal, functionality, and environmental friendliness, and the booth was designed in accordance with the basic principles of the Manners Book. While sustainability initiatives are diversifying, we are also continuing to take on various challenges, such as developing upcycled materials. However, this time, we returned to basic materials that are indispensable for constructing spaces and that we will continue to be deeply involved with in the future, and focused on understanding the characteristics of each material. As basic materials, we used wood, cement, acrylic, copper, and iron, arranging the timbers of each material in a grid pattern while creating undulations in the space, allowing visitors to move around the booth and enjoy conversations. The proportion of each material used was calculated based on the embodied carbon emissions throughout the building's lifecycle, and we made efforts to allow visitors to visually perceive the characteristics of each material. Furthermore, by using clamps (*) instead of screws or adhesives for joining, the materials can be reused, and the amount of waste generated during demolition is drastically reduced, symbolically representing the fundamental concept of contributing to the environment. Our aim was concept design a booth where visitors could think together about future approaches to sustainable concept design, and where they could gain new insights and discoveries while demonstrating responsibility and gratitude for materials. *We are using the dedicated clamps from the "Tsunagi" project, planned and produced by Nikken Sekkei.
