Tokyo-based YKK Fudosan Co, Ltd, part of YKK Group’s global network, has obtained LEED-BD+C (Core and Shell) Platinum certification for its YKK80 Building. It was the first such certification for a new office building in Japan. The goal of the project team was to reduce energy consumption by 60% when compared to typical office buildings. To achieve this, the design prioritized water and energy efficiency along with a healthy indoor environment. Open space within the seismically isolated structure was utilized as a heat sink for the geothermal heating system of the building. Other features include sensors for day-lighting and motion-activated operability, outdoor air cooling and mist facilities for the exterior shaft, radiant panels, desiccant air cooling, and high-performance electrical outlets.
