About the Council The Council on Tall Buildings and Urban Habitat is the world’s leading resource for professionals CTBUH Journal focused on the inception, design, construction, and International Journal on Tall Buildings and Urban Habitat operation of tall buildings and future cities. A not-for-profi t organization, founded in 1969 and based at the Illinois Institute of Technology, Chicago, CTBUH has an Asia offi ce at Tongji University, Shanghai, and a research offi ce at Iuav Tall buildings: design, construction, and operation | 2015 Issue II University, Venice, Italy. CTBUH facilitates the exchange of the latest knowledge available on tall buildings around the world through publications, Special Issue: Focus on Japan research, events, working groups, web resources, and its extensive network of international representatives. The Council’s research department Case Study: Abenos Harukas, Osaka is spearheading the investigation of the next generation of tall buildings by aiding original Advanced Structural Technologies research on sustainability and key development For High-Rise Buildings In Japan issues. The free database on tall buildings, The Skyscraper Center, is updated daily with detailed Next Tokyo 2045: A Mile-High Tower information, images, data, and news. The CTBUH Rooted In Intersecting Ecologies also developed the international standards for measuring tall building height and is recognized as Application of Seismic Isolation Systems the arbiter for bestowing such designations as “The World’s Tallest Building.” In Japanese High-Rise Buildings Innovative Façade Systems of Japan Fire-Resistant Design of Tokyo Sky Tree Talking Tall: Hiroo Mori Council on Tall Buildings and Urban Habitat S.
