PHIUS Executive Director Katrin Klingenberg wins Women in Sustainability Leadership Award

Washington – November 18, 2015 – WASHINGTON – Passive House Institute US (PHIUS) co-founder and Executive Director Katrin Klingenberg has been awarded one of Green Building & Design (gb&d)’s Women in Sustainability Leadership Awards.

“I am proud to receive this honor and to be counted among this remarkable group of women. I’m grateful for the community of forward-thinking, committed passive house professionals and advocates who have made passive house a market force in the United States.”

Other 2015 award recipients include Robin Chase, founder of Zipcar, Lori Duvall, director of global impact at eBay and Arlene Blum, founder and executive director of the Green Science Policy Institute. Click here to see the full list of recipients.

Klingenberg, a German-born architect, designed and built the first "passive house" in the United States in Urbana, Ill. in 2003. The project sparked intense interest, and Klingenberg co-founded the Passive House Institute US (PHIUS) with the mission of making passive building principles and performance standards a mainstream market standard. Klingenberg introduced the Certified Passive House Consultant (CPHC®) training and certification programs in 2008.

Klingenberg has forged strategic partnerships to advance passive building. Through an agreement with the U.S. Department of Energy, the PHIUS+ Certification program also earns projects the D.O.E.’s Zero Energy Ready Home status. Working with D.O.E. and RESNET, PHIUS developed the first and still only third party quality assurance program for passive buildings.  On the research front, Klingenberg led collaboration with Building Science Corporation on a three-year, DOE-funded study that yielded a climate-specific passive building standard for North America. The John D. and Catherine T. MacArthur Foundation recently recognized PHIUS’ work with a grant to support passive building for affordable housing.

The judging panel for the 2015 Women in Sustainability Leadership awards included Chris Howe and Laura Heidenreich of Green Building & Design Magazine, Rochelle Routman of Mohawk Industries, Kimberly Lewis of the U.S. Green Building Council, and Charmaine Atherton of Bank of America Merrill Lynch. Past award winners include U.S. Secretary of State Hillary Clinton, Cindy Ortega, Chief Sustainability Officer of MGM Resorts International, Arielle Bertman, Principal of Energy and Sustainability at Google, and Daniele Horton, Founder and Principal of Verdani Partners.

Klngenberg will receive her award at the Greenbuild Conference & Expo in Washington D.C. on Nov. 19.
