Karagiozis comes to NREL from Owens Corning where he was the global director of building science and led global accountability for the company's building science strategy. During his 9-year tenure, he shaped, educated, and trained others in energy efficiency and green building science, transforming building science into a growth engine aimed at accelerating energy-efficiency improvements in the built environment.

Before joining Owens Corning, Karagiozis was a distinguished researcher at Oak Ridge National Laboratory, where he worked for 16 years. He chairs ASHRAE Standard Project Committee 160, which specifies criteria for designing high-performance buildings. He was an Energy and Environmental Building Alliance board member and served on the Passive House Institute U.S. Technical Committee.
