NOMURA exhibited a booth at the SC Business Fair 2024, the largest event in the industry where shopping center personnel gather together. The event was held at the Pacifico Yokohama displays Hall for three days from January 24 to 26, 2024, and in addition to exhibiting at a booth, we also held a free seminar on the first day of the event. The theme of this booth was "NOMURA Idea of Sustainable concept design." As part of our social good R&D activities, we are currently working on creating a "Sustainable concept design Manner Book" that realizes design, functionality, and environmental friendliness, and our booth was designed in accordance with the basic principles of the manner book. As sustainability efforts become more diverse, we are also continuing to take on various challenges, such as developing upcycled materials. However, this time, we have focused on understanding the characteristics of basic materials, which are indispensable materials for constructing spaces and will continue to be deeply involved in the future. The basic materials used were wood, cement, acrylic, copper, and iron. The lumber was arranged in a grid pattern, but the space was given an undulation, allowing visitors to walk around and enjoy conversation. The ratio of each material was calculated based on the embodied carbon emissions in the building's life cycle, and the characteristics of the materials were visually conveyed. In addition, the joints were made using clamps (※) instead of screws or adhesives, allowing the materials to be reused and reducing waste at the time of demolition, symbolizing the essential idea of contributing to the environment. We aimed to concept design a booth that would allow visitors to think about future approaches to sustainable concept design together with us, and that would allow visitors to gain new realizations and discoveries while showing their responsibility and gratitude for materials. *We have used the dedicated clamps from the "Tsunagi" project, planned and produced by Nikken Sekkei.
