Katrin Klingenberg

Ex-Officio PHIUS Board Member -- Co-Founder & Executive Director, Passive House Institute US (PHIUS)

Katrin Klingenberg designed and built the very first home in the United States built to the passive building energy standard. Her experience led her to co-found e-cological Construction Laboratory (e-colab) with builder Mike Kernagis in 2003 as a non-profit affordable housing developer in Urbana, Illinois to further investigate the feasibility of applying passive building principles in the United States. As interest in passive building grew in North America, Klingenberg and Kernagis 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.

Klingenberg has since designed and consulted on numerous passive building projects across North America’s varied climate zones. In her role as Executive Director of PHIUS she directs the technical and research programs of the organization. In addition to her executive role, she is also the lead instructor and director of curriculum development for the PHIUS Certified Passive House Consultant (CPHC®) Training program. Klingenberg earned the German equivalent of a B.S. in Architecture at the Technische Universität in Berlin, Germany, earned an M.S. in Architecture from Ball State University, and is a licensed architect in Germany.

Richard S. Levine

Co-Director, Center for Sustainable Cities

Richard S. Levine, the principal architect and Co-Director at the Center for Sustainable Cities Design Studio, is an award winning environmental architect, a solar energy and sustainability pioneer, and Professor Emeritus at the University of Kentucky. He was an early solar architecture proponent, starting with his innovative Raven Run Solar Home of 1975. His sustainable city research has been the foundation of urban development projects in China, the Middle East, Austria, Italy, and the United States. In 2010 Levine was named “Passive Solar Pioneer” by the American Solar Energy Society to honor his lifetime achievements in solar design.

Levine and colleague Ernest J. Yanarella founded the Center for Sustainable Cities (CSC) at the University of Kentucky. Their book entitled The City as Fulcrum for Global Sustainability, was published in 2011. Partnering with Dr. Heidi Dumreicher, Director of Oikodrom at the Vienna Institute for Urban Sustainability, the CSC identified the city-region as the master scale at which homeostatic balance could be achieved among social, environmental, economic, urban, and governance issues. The CSC Design Studio has completed seven Net Zero Houses, four of which were done for low-income families and are PHIUS+ certified.
