Special Features

Q-1 Indoor Environment
  • Ecological roof system that lets daylight into rooms thoroughly
  • Solar radiation control system/Peri-buffer system that reduces air-conditioning loads while allowing for open space structure
  • Displacement natural ventilation system for large-scale space
  • Sensible/latent heat separated personal radiant air-conditioning system that treats for comfortable and energy-saving
  • Use of task/ambient lighting system. Flicker control of task lights using IC tags
  • Introduction of air-conditioning system using blower outlet on the floor in the workplace, and control of CO2 emissions
  • Personal floor diffusing air-conditioning system, and CO2 monitor control system.
Q-2 Quality of Service
  • A wide and open workspace with a vaulted high ceiling
  • Ensuring flexibility by adopting large span frames and separated cores
  • High seismic capacity (seismic isolation structure/Super active vibration control structure)
  • Enhanced reliability through installation of advanced information network systems, power generators and uninterruptible power systems (UPS)
  • Rainwater and well water treatment system
  • Preparation of gravity water supply system for toilets and emergency sewage tanks as a disaster preparedness
Q-3 Outdoor Environment on Site
  • Mitigating impact on the surrounding environment by adopting low-rise building design and keeping large green space
  • Improved thermal environment by introducing wet type of exterior pavement materials
LR-1 Energy
  • 36 % reduction in PAL value
  • 42 % reduction in ERR value, an integration of CEC values
  • Natural energy utilization system including photovoltaic (150 kW) /wind power generation, utilization of daylight, geothermal power and natural ventilation
  • Visualization system utilizing BEMS for raising environmental awareness of occupants of the building
LR-2 Resources and Materials
  • Cascade using rainwater and well water for saving resources
LR-3 Off-site Environment
  • Decided location of facilities and trees with consideration for prevailing wind and thermal environment
  • Appropriate sound-deadening silencer for equipment on the roof

These cases are described based on assessment results obtained using CASBEE.
CASBEE is a method for rating the environmental performance of buildings using Building Environmental Efficiency (BEE) as an indicator, which is based on the results of separate scores obtained for Q-1~Q-3 (Quality) and LR-1~LR-3 (Load Reduction).
