CHICAGO Twelve of the world’s best-known structural engineering firms helped the CTBUH Research Team to perform a fundamental part of its LCA research project, “A Whole Life Cycle Assessment of the Sustainable Aspects of Structural Systems in Tall Buildings,” sponsored by ArcelorMittal.
Research sponsored by:

The Research is aimed at assessing the environmental impacts and energy consumption of tall-building structures, from the production of the building materials to their end-of-life.

The following firms provided the CTBUH with material quantities of 16 different structural scenarios, eight for a 248-meter tall tower, and eight for a 490-meter-tall tower that, if constructed, would be the fifth tallest in the world:
Structural scenarios include: all-concrete construction, composite columns, 100 percent steel diagrid structures and mixed structures with concrete cores and steel columns.

The next phase of the research will study the end-of-life scenario of tall buildings (limited to the 248-meter-tall scenarios) with the involvement of leading international demolition companies.
