NARRATIVE

The Obayashi Technical Research Institute (TRI) Techno Station, located in Tokyo, Japan, is a 59,552 sq. ft. R&D facility for innovative building designs and technologies, which are tested at the facility for potential implementation in Obayashi’s global construction projects.

The Institute currently holds the third highest LEED EBOM score in the world–out of over 6,000 registered projects globally–and also scored one of the highest ratings ever achieved in Japan’s Comprehensive Assessment System for Built Environment Efficiency (CASBEE) green building rating system.

SUSTAINABLE FEATURES
  • Peri-buffer system: a thermal buffer zone established around windows that reduces air-conditioning loads in low-occupancy building zones
  • Task/ambient lighting/air-conditioning that allows employees to set their own levels, and uses IC tags to only operate when employees are present
  • Slanted roof panels with ventilation slits that allow for natural daylighting, ventilation and temperature control
  • Solar panels that generate enough energy for nighttime workspace lighting
  • Natural ventilation displacement system that utilizes temperature and CO2 sensors to activate floor vents
  • Hybrid heat pump system that utilizes both geothermal and well water heat
