Urban High-Rise Office Building That Contributes to a Sustainable Society

The concept of a sustainable society and urban regeneration was pursued with three keywords in this project; the global environment, human beings and local connections. Various new environmental technologies were also installed to maximize the reduction in CO2 emissions and improve workplace productivity. The most remarkable feature was the installation of a ceiling radiant air conditioning system of 30,000 sqm which is the largest of its kind in Japan. This building was designed mainly with radiant air-conditioning as part of efforts to achieve net ZEB (Zero-Energy Building) in the near future. On completion, continuous measurement and evaluation have been conducted.
