About Us

Passive House Minnesota is a group of Minnesota-based Passive House professionals and practitioners who aim to educate about and promote the Passive House building energy standard. We are located in Minneapolis, Minnesota, USA.

We are members of the International Passive House Association “iPHA”, the North American Passive House Network “NAPHN” and founding members of the Passive House Alliance U.S. “PHAUS”.

Passive House Minnesota was founded by Tim Delhey Eian of TE Studio in 2008. Since then, it has supported the building standard in the state of Minnesota, its neighboring states and throughout North America.

Minnesota is home to North Americas’ first certified Passive House, the Waldsee BioHaus, designed by North American Passive House pioneer and registered Architect Stephan Tanner in 2005 and completed in 2006. It represents ground zero for the World’s leading building energy standard in North America.
