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).
