The two-day CTBUH 2022 Steel-Timber Hybrid Buildings Conference convened the leading international experts in steel and timber design and construction, to explore how the benefits of each can be utilized to advance tall steel-timber hybrid buildings. Taking place at Mies van der Rohe’s essential masterpiece, the 1956 S.R. Crown Hall at the Illinois Institute of Technology (IIT), Chicago, the conference was organized by the Council on Tall Buildings and Urban Habitat (CTBUH), with the support of both constructsteel, a World Steel Association program, and the Softwood Lumber Board (SLB). It represented an essential element in the two-year CTBUH research project, “The Future Potential of Steel-Timber Hybrid Buildings,” sponsored by constructsteel and SLB.

 

Some 250 delegates from around the world were in attendance, hearing 36 concise presentations on the most significant steel-timber hybrid buildings completed, under design or under construction today, as well as the latest advances in academic research, followed by targeted breakout meetings covering key disciplinary topics. These included Architecture/Design, chaired by Andrew Waugh, Founding Director, Waugh Thistleton Architects; Structural Engineering/Life Cycle Cost Analysis (LCCA) chaired by Antony Wood, President, CTBUH; Construction Logistics, chaired by Lisa Podesto, Senior Business Development Manager, Design-Build Americas, Lendlease; and MEP Systems & Envelope/Façades, chaired by Susan Jones, Principal Architect, Founder, atelierjones.

 

 

Delegates participate in engaging conversations during the MEP Systems & Envelope/Façades breakout meeting.

 

 

The break-out meetings represented an expansion of the steering committee to include new practitioners and an advancement of the research project to the next stage: the focused development of case studies and modeling scenarios to evaluate the relative carbon and cost implications of various configurations of steel and timber in a high-rise context. The Council looks forward to advancing this critically important research.
