NOMURA Co.,Ltd. exhibited a booth at the "SC Business Fair 2024," the largest event in the shopping center industry, bringing together all involved. The event was held at the Pacifico Yokohama displays Hall for three days, from January 24 to 26, 2024. In addition to exhibiting at our booth, we also hosted a free seminar on the first day of the event. The theme of our booth this time was "NOMURA Co.,Ltd. 's Approach to Sustainable concept design." As part of our social good R&D activities, we are currently working on creating a "Sustainable concept design Etiquette Book" that achieves aesthetics, functionality, and environmental friendliness. Our booth was designed in accordance with the book's basic principles. As sustainability initiatives become more diverse, we are also continuing to take on various challenges, such as developing upcycled materials. However, this time, we focused on understanding the characteristics of basic materials, which are essential for creating spaces and will continue to be deeply involved in the future. The basic materials used were wood, cement, acrylic, copper, and steel. Each timber was arranged in a grid pattern, creating undulating spaces that encouraged visitors to wander and enjoy conversation. The proportion of each material used was calculated based on the embodied carbon emissions over the building's lifecycle, allowing visitors to visually appreciate the material's characteristics. Furthermore, clamps* were used instead of screws or adhesives to join the pieces, enabling secondary reuse of materials and dramatically reducing waste during demolition, symbolizing the essential concept of contributing to the environment. Our goal was to concept design a booth that would encourage visitors to consider future approaches to sustainable concept design, while demonstrating responsibility and gratitude for materials and fostering new insights and discoveries. *We have used clamps specifically designed for the "Tsunagi" project, planned and produced by Nikken Sekkei.
