Ken Levenson, Executive Director
Ken graduated from Pratt Institute with a Bachelor of Architecture. After practicing architecture for 20 years in New York City, and in a climate panic, he discovered Passive House in 2009. He then became a Certified Passive House Designer and started designing Passive House buildings. To increase impact, in 2010 Ken became a founding board member of New York Passive House, the National Passive House Alliance, and in 2011, NAPHN, an organization that would become The Passive House Network – all nonprofits dedicated to popularizing Passive House through education. Working on projects Ken realized there was a gap in the American market of critical high performance Passive House building products and the practical knowledge needed for their correct use, so in 2011 Ken closed his architecture firm, and co-founded the company 475 High Performance Building Supply with a mission to supply essential materials, building components, and knowledge to help drive industry change. Ken has served on advisory panels for Urban Green’s 90 by 50 policy report and the Framework Guidelines for Energy Efficiency Standards in Buildings of the United Nations Economic Commission for Europe. Then in 2019, in a growing panic, Ken stepped down from the boards of PHN and NYPH and the management of 475 and volunteered with Extinction Rebellion, planning and participating in direct action civil disobedience protests to demand governments declare a climate emergency.
While his daughters thought his getting arrested was the only cool thing he ever did, his journalist wife suggested that he get a job, and so in 2020 Ken returned to PHN as its first Executive Director, focused on Passive House capacity building across the US.
When not thinking about Passive House or hanging out with his wife and daughters, Ken can often be found walking their Newfoundland dog in Prospect Park.
