Performance in Future Sustainable Tall Buildings

Mark Sarkisian, Benton Johnson, David Shook, Stephen Ray

Performance through quantification and verification is at the heart of sustainability in next generation buildings. In decades past, tall buildings were a novelty; designed and built with significant materials, redundancy, and limitations. While past approaches to building systems were appropriate at the time, these systems had minimal sustainability considerations, were expensive, cumbersome, and limited by the design tools of the era.

Performance quantification through technical calculations have grown exponentially giving rise to advancements in design, but this technical growth has not been well complimented with performance verification. With thousands of ever taller buildings projected worldwide in the coming decades, the need for rigorous verification is critical as higher efficiencies, new building systems, and less redundancy are sought to reduce climate impacts. This issue affects all trades including structural gravity systems, structural seismic and wind lateral systems, mechanical systems, and exterior wall systems.

The proposed presentation and presentation will survey industry-wide multi-disciplinary considerations of next-generation performance-based design opportunities and present case studies from several projects using advanced quantification and verifications methods to reduce climate impacts and increase resiliency. Topics include hybrid high-rise timber systems, advanced floor framing systems, high-efficiency mechanical systems, high-performance seismic systems, verification of construction using advanced computational algorithms. Current building system sustainability approaches primarily focus on reducing material by removing redundancies once perceived to be needed. The presented next-generation approaches move beyond reducing material and energy costs into higher levels of performance, aesthetics, and sustainability.
