Help Make Passive Building Mainstream Support PHIUS

Council Members

The PHIUS Alliance is comprised of elected members chosen for their commitment to the promotion of the Passive House Building Standard, their professional experience and their geographic diversity. Currently, the Council consists of members nominated by PHIUS in 2010 and members elected by The PHIUS Alliance regional membership. There are 11-13 Council members: 8 Regional Representatives representing the climatic regions of the US, and 3-5 at large and officer positions. Council members serve terms of three years and are not compensated for their work. The Council meets monthly and at least once in person.

Zane Goodwin

Southeast Regional Representative

Zane Goodwin, CPHB, RGC is leading the Southeast's fight to make high performance homes the norm. He is a Certified Passive House Builder and runs the Design + Build firm- Home and Made Custom Builders LLC. in Atlanta Ga. Not coming into the performance home world via the normal route of Architecture, he fell in love with the sustainability and durability aspects of homes through renovationing 50-100 year old homes. He got to see the fail points of these old homes and vied to build homes better so they didn't have the same fate. Building better, more durably, turned into a love of building science and ultimately brought him to Passive House. 
Zane now lives in the High Performance Custom New Build and Energy Retrofit/ Renovation part of the industry. Zane Is also a proud US Army Infantry Veteran.

John E. Avenson

Southwest Regional Rep, Certified Passive House Consultant (CPHC®)

Representing: Nevada, Wyoming, Arizona, Colorado, New Mexico

John Avenson built his Passive Solar and voice controlled home in 1981 after observing and being inspired by the NREL (National Renewable Energy Labs) Competition for the Parade of Solar Homes in the Denver/Boulder area. He has been an advocate of low energy use homes ever since, going so far as to invite what is now a total of over 6000 people on personal and organized groups tours through his home. This home is of the Mass-and- Glass concept popular back then. In 2013, John took the CPHC® course and began the process of updating his “passive heated house” to “passive house” standards. It no longer needs a furnace.

John is a lead member of the ASES/CRES National Tour of Solar and Sustainable homes for the Denver area and has interviewed and photographed solar and sustainable homes for publication since 2000. John is a DMTS of AT&T Bell Labs (Distinguished Member of Technical Staff) Electrical Engineer - retired after 42 years of traveling the world fixing telephone systems and training telco engineers. He became interested in passive heated homes in 1962 after his father took the family to a Geodesic dome house and to the Native Indian Cliff dwellings of Southern Colorado and as a result, dreamed of having a home like Indians all through elementary school. His goal is to be off-grid within the next decade.

John owns his own FLIR camera and other building analysis instruments. He has taught about home energy efficiency at Lockheed/Martin, Sandia Laboratories NM, NREL and many community events.

Tom Bassett-Dilley

Midwest Regional Rep

Representing: North Dakota, South Dakota, Nebraska, Minnesota, Iowa, Wisconsin, Michigan, Illinois, Indiana, Ohio

Tom Bassett-Dilley, CPHC, AIA, founded his firm in 2006 to pursue sustainability as contemporary design based on region, climate, and context. Toward that end, he became a CPHC in 2010 to learn advanced energy modeling, building science and principles of conservation exemplified by the Passive House standard. He is a founding member and past President of the Chicago PHAUS chapter and has presented numerous times for PHAC and at PHIUS' annual conferences.

His first certified project was completed in 2013, with two more fully certified, three pre-certified, and several more PH projects in the works, including an institutional renovation/addition project. Tom sees the beauty of the Passive approach in its ability to optimize energy design concurrently with architectural design, its tendency toward simplicity in form and glazing, and its tendency to require "tuning" a building to site-specific solar access.

He is very encouraged by the direction that PHIUS+ 2018 has taken and is eager to continue to help build awareness and momentum toward adoption of the PHIUS standard.

Jonathan Bean

At-Large Council Member

Jonathan Bean is Assistant Professor of Architecture, Sustainable Built Environments, and Marketing and chair of the Sustainable Market Transformation program at the University of Arizona. He was the faculty lead for the University of Arizona's team in the 2018 Race to Zero Student Design Competition.
