Dr. Yun Kyu Yi teaches environmental and sustainable architecture and technology and conducts research in the area of computational building modeling and simulation, building performance evaluation and indoor occupants behavior. He is also founder and lead investigator of the Responsive Architecture Lab (RAL) at the Illinois School of Architecture. 

Previously he has lectured several universities in Korea and taught at the University of Pennsylvania, where he was an assistant professor at the department of architecture and primary faculty of the TC Chan Center for Building Simulation and Energy Studies. He is also the founder and investigator of Envitect. Enterprise seeks to develop an application for performance-based design support that links research outcomes to the development of new processes, systems, and products.

He is a lead author or co-author of numerous scientific papers. He recently published “Developing an advanced daylight model for building energy tool to simulate dynamic shading device,” in the Solar Energy and "Programmable Kiri-Kirigami Metamaterials," in the Advanced Material.

He wrote a chapter called “Building Performance and Computational Simulation,” in “The Design and Construction of High-Performance Homes Building Envelopes, Renewable Energy and Integrated Practice,” edited by Franca Trubiano. He also contributes a translation of “The Design and Construction of High-Performance Homes Building Envelopes” into Korean, and the translated book was awarded for 2015 Sejong Outstanding Scholarly Book in Korea.

He worked on several consultant projects on energy saving, high-performance building design and operation. A Recent project includes University of Pennsylvania Carbon Reduction Action Plan that provided strategic guidance on building energy conservation and Qatar Sustainability Assessment System, which is a performance-based sustainability rating system.
