Structure of this Magazine

This magazine presents Takenaka Corporation's New Tokyo Main Office Building from a variety of different perspectives. We have strived to provide an easy-to-understand description of the three key themes of the design of the New Tokyo Main Office Building: the creation of a highly efficient and high-quality workplace; the reduction of environmental load; and the pursuit of cost-performance. Chapters 1 to 6 present the features incorporated into the New Tokyo Main Office Building as sustainable architecture, in line with the framework of "Sustainable Works," which is a concept of Takenaka Corporation, and Chapters 7 and 8 deal with the workplace and IT respectively. Chapter 9 presents architectural details.

New Tokyo Main Office Building - Aiming for Factor 4 or Above Integrating design and engineering

Factor 4 advocated by Weizsaecker and other scientists aims to double affluence, halve resource consumption, and quadruple resource productivity by revolutionizing efficiency. The environmental efficiency in CASBEE (Comprehensive Assessment System for Building Environmental Efficiency) is based on the same approach.
In creating the New Tokyo Main Office Building, we aimed for Factor 4, i.e.,a building environmental efficiency (BEE) of 4.0 or higher in CASBEE. By integrating the design and engineering technology which Takenaka has traditionally developed through members of its design, structure, facility, construction and technical teams, design and construction with a viewpoint connected with cost were carried out while reviewing feedback using Takenaka Comprehensive Assessment System for Building Environmental Efficiency. As a result a high environmental performance with a BEE of 4.6 was achieved.The building environmental performance (BEE) exceeds 4, meaning it is located within the region exceeding Factor 4.
