The building's high energy efficiency and the rich outdoor environment on the top floor and intermediate floors has earned it the highest rank ("S") in the Comprehensive Assessment System for Building Environmental Efficiency (CASBEE). The Orix Hommachi Building represents a new standard in ultra-high rise office buildings, offering broad versatility and balancing safety, quality and environmental performance. (Hiroshi Arita)受けている。安全・品質・環境性能のバランスのとれた、超高層オフィスの新しいスタンダードとして広い汎用性を示している。�(有田 博)Unlike most ultra-high rise office buildings which are of steel construction, the Orix Hommachi Building was built using seismic isolated structure to improve operational continuity in the event of an earthquake. The building has an upper structure of highly rigid steel reinforced concrete and reinforced concrete construction. In the construction process, the prestressed concrete components were 26Works
