Daniel Overbey is passionate about making a sustainable difference in our world, and he inspires his clients, colleagues, and future architects to do the same. His research-based background in building science and environmental systems has made him an effective design leader, educator, and policy shaper.

Daniel is a committed and enthusiastic volunteer at the local, state, and national levels of the AIA and USGBC. His work on numerous code review committees of the Indiana Department of Homeland Security resulted in policy changes that have shifted the course of design practice in Indiana. He has served on the Board of Directors of both AIA Indianapolis and USGBC Indiana and regularly lobbies state and national legislators on behalf of the building design and construction industry regarding issues and policies that support green building practices, mass transit, and high-performance schools.
