Track: Tall Buildings

Chair: John Carter, Member, CPP, Fort Collins, CO

Chicago has a strong heritage of tall buildings, from turn of the century Home Insurance Building, to John Hancock Center and Willis Tower. What are the Chicago tall buildings HVAC designers up to today? This session introduces the next generation tall building design, from new weather files, new environment contaminant files, low energy tall building, healthy tall building, to new stack effect studies, modular building, etc. Three Chicago firms, including three HVAC designers of the top 20 tallest buildings in the world by 2020, discuss what they see on the tall building horizon.

1. The Current Tallest Building Design Update
Mehdi Jalayerian, P.E., Member, ESD, Chicago, IL
This session discusses the HVAC and primary building systems design and current update on the next tallest building in the world – Kingdom Tower. The session reviews next generation design parameters and system zoning and configuration to achieve systems reliability and efficiency including stack effect management, envelope performance, lobby configuration and space pressurization. Building Systems design for super-tall buildings must be developed through early integration with the structural and architectural design as configuration and organization of the building can significantly influence the building systems solutions, systems operation and ultimately installation cost

2. Low Energy Tall Building Design and Modular Tall Buildings
Robert Tazlaar, Member, ARUP, Chicago, IL
This presentation provides some insight into how HVAC systems are changing to meet the drive towards lower energy usage. It primarily focuses on trends in designs which have been highlighted in research journals and project work. A case study is provided which highlights how some of the trends have been implemented on a current design.

3. Low Carbon and Healthy Tall Buildings
Luke Leung, P.E., Skidmore Owings & Merrill, Chicago, IL
From the environmental information, including microclimate to contaminants variation with height, to the wellness and integration to urban habitats, our current tall building design needs to be strengthened for the next generation of taller and more diversified buildings. This discussion focuses on the areas that need to be strengthened and how we can achieve that in the next generation tall building design that delivers lower energy and healthier tall buildings.
