Effective U-Value of Curtain Walls

Scott Bondi, PhD, PE, LEED AP Scott Bondi is a Mechanical Engineer with experience in many aspects of building physics, numerical analysis, façade design and mechanical systems. His design experience has included work on large commercial office buildings, data centers, museums, as well as public facilities. Scott is particularly skilled in the use of modeling techniques to predict systems performance. His modeling experience includes the extensive use of Computational Fluid Dynamics software (CFD) to predict airflow and humidity migration patterns. He also has experience using Finite Element software (FEA) to predict the structural and thermal performance of façade systems. His structural modeling experience has included non-linear structural analysis, using advanced tools such as LS-DYNA. In addition to using simulation techniques, Scott has also carried out historical weather studies to assess façade performance and risk using statistical analyses. He has also performed work in the field of overall building performance through the use of energy modeling. Scott is an Adjunct Professor at The Cooper Union in New York City, where he has lectured and developed courses in Finite Element techniques, Computational Fluid Dynamics and Solid Mechanics. Robert Tazelaar, PE, LEED AP Robert leads Arup Chicago’s MEP group. He has more than 24 years of experience in the design and project management of varied building and project types encompassing office, performing arts, residential, commercial, retail, mission critical, institutional, and sustainability. Robert’s primary expertise is in design of HVAC systems, and he has supervised and participated in the design of several LEED certified buildings. He focuses his efforts on meeting the owner’s criteria for building operation and cost while championing sustainable design practices and energy efficiency.
