Co-Founder & Program Director
James M. (Mike) Kernagis was one of the first American builders to adopt passive building principles and build projects that meet the passive building energy standard.
In 2003, he and Katrin Klingenberg co-founded e-cological Construction Laboratory (e-colab) as a non-profit affordable housing developer in Urbana, Illinois to further investigate the feasibility of applying passive building principles in the United States. In 2005 he served as construction manager for the affordable housing units built to the passive building standard in cooperation with the City of Urbana.
As interest in passive building grew in North America, Kernagis and Klingenberg oversaw the expansion of e-colab into Passive House Institute US (PHIUS) in 2007. PHIUS is now the leading passive building standard setting, research and information provider, training, and certification institute in North America. In his role as Program Director of PHIUS, Kernagis has overseen PHIUS operations, training, and membership programs since its inception. In 2012 Kernagis helped launch the PHIUS Certified Builder Training program, where he was instrumental in the development of its curriculum and continues to serve as a lead instructor for the program.
Executive Director & Co-Founder
Katrin is the executive director of the Passive House Institute US (PHIUS), Chicago, Illinois, USA. PHIUS is an organization committed to making high-performance passive building the mainstream market standard.
After studying at the Technische Universitaet in Berlin, Germany and graduating from Ball State University in Muncie, Indiana with a master’s degree in architecture in 1996, Katrin began her career in architecture with Murphy/Jahn in Chicago, Illinois. She then worked for the architecture firm Solomon Cordwell Buenz in Chicago. In 2002, she started her own firm and became a registered architect in Germany.
In 2007, Katrin co-founded the Passive House Institute US to work on education. She is the executive and the lead instructor for the PHIUS Certified Passive House Consultant (CPHC) training. She also directs the technical and research programs at PHIUS which has trained over 2,000 architects, engineers, energy consultants, energy raters and builders in passive building standards. PHIUS has become the leading passive building research and information provider in North America.
Katrin has written and co-authored magazine articles and book contributions. She has also presented internationally on the topic of passive building science and won the Woman in Sustainability Leadership Award in 2015.
