Japan Sustainable Building Database

Project Outline

This building is a central workplace for Obayashi Corporation that strives for innovating, demonstrating and disseminating technologies. It was built to establish a new R&D base that creates new technologies through integrated research functions and intellectual exchange, applies and demonstrates own technologies, and disseminates them to our clients and the society.
With an aim to create an environmentally-friendly workplace, the building adopted a complex passive system that utilizes its location in a suburban area, an active facilities system with high effectiveness, and a management system for efficient/effective energy use. These three systems allowed for 55 percent reduction in CO2 emissions during operation, the highest level in Japan. Furthermore, the building was rated as S rank of CASBEE and achieved 7.6 scores of BEE because of the overall reduction in environmental burdens.
