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.
