Ryan Abendroth

Ryan Abendroth feels strongly about the ever increasing need for energy efficiency in buildings which led him to work with hundreds of passive house projects including small residential designs and student projects to mid-sized commercial and non-profit developments.

Professionally, Ryan has been at the forefront of research and design in passive houses for almost a decade. He began modeling his first Passive House in 2008. In 2009, he joined the Passive House institute US as the Certification Manager where he reviewed every project for compliance with the Passive House Certification process over the course of almost 4 years. And concurrently, in January of 2010 founded Passive Energy Designs a St. Louis, MO based consulting firm specializing in achieving built high-performance and low-energy buildings that meet the passive house standard.

Ryan holds a Master of Architecture and a Bachelor of Science in Architectural Studies from the University of Illinois at Urbana-Champaign. His design education and research focused on energy efficiency and building science, which led to a thesis entitled ”A Critical Analysis of the Passive House Standard for the Climates of the United States.” This thesis helped lay the groundwork for the PHIUS+2015 Standard and the Building America Study which developed it.

Currently, Ryan is a lecturer at the Sam Fox School of Design and Visual Arts at Washington University in St. Louis where he teaches both graduate and undergraduate courses focused on the impacts of climate, site, energy, detailing, and building information modeling (BIM) on the built environment. Previously he taught at the Rhode Island School of Design as both a Visiting Lecturer and Critic and has acted as a passive house consultant for Kansas University’s 5th year design-build program, Studio 804.
