As interest in environmental issues has grown, so has the number of properties applying for CASBEE® certification* or providing notification of self-evaluation in the past several years. In addition, some projects have been selected by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) for the "leading projects" program for sustainable buildings and by the Ministry of Economy, Trade, and Industry (METI) for the "net zero energy building" experimental pilot program.

*The comprehensive assessment system for built environment efficiency (CASBEE) certification is an environmental performance evaluation system for buildings being developed and promoted in Japan under the guidance of MLIT.

Case Study C


Situated adjacent to the Atomic Bomb Dome (Hiroshima Peace Memorial), this office building underwent full-scale renovations. The existing framework was reused and the building enlarged to accommodate a higher level of earthquake resistance. A large canopy, louvers, and a "spiral slope" walking ramp were also built into the newly expanded sections. The building reduces its CO2 footprint by utilizing various energy-saving features, including solar shading and cross ventilation. Visitors to the building can access the HIROSHIMA HILL observation deck under the giant canopy on the roof, enjoy numerous activities in ORIZURU Square, and learn about its CO2 reduction initiatives.

The ORIZURU TOWER was selected for the MLIT’s leading projects program for promoting CO2 reduction in housing and buildings.
