John E. Avenson

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

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.

Lance Wright

Certified Passive House Consultant (CPHC®)

Green Energy Man

Lance Wright graduated from Auburn University with a degree in the Forest Ecology Honor’s Program in 1976 and worked with the U. S. Forest Service in Colorado, Idaho, Oregon and Alaska until 1983. He then went on to work for Democratic and environmental campaigns in Colorado through several election cycles, including three of his own runs for a seat in the State House of Representatives, before being elected to the Parker Town Council in 1996 and re-elected in 2000.

In 1998, Lance built his first energy efficient house, and his low heating bills helped him convince fellow Council members to increase building code requirements for energy efficiency in the Town of Parker. In 2002 he was the Democratic candidate for Congress against Tom Tancredo in the heavily Republican Sixth District. Lance ran on an anti-terrorism, energy-independence platform that was called “aggressive” and “unrealistic” by the Rocky Mountain News in its endorsement in the race. He moved to Springfield, Missouri in 2004 for family reasons and became the first US EPA Energy Star building partner in southern Missouri.

After building Energy Star rated homes in Missouri for two years, Lance returned to Colorado and established the energy efficiency design and consulting business, Green Energy Man, Inc. Lance was part of the charter group of Passive House Consultants trained by PHIUS in the fall of 2008. He and his wife live in Denver in their “Near Passive House”, which they are currently retrofitting to gain Passive House Certification.
