Graham Irwin, AIA, CPHC®, is the principal of Essential Habitat Architecture, a Northern California design firm focused on healthy, high performance, sustainable buildings built to Passive Building standards. He has a degree in physics, with additional studies in engineering and architecture, and an extensive background in software development.

Allison Bailes has a broad range of experience and education, but at heart, he is a teacher. He taught physics at the high school and college level. After building a high-performance home in 2001, he launched himself into a new career in the world of building science. For most of this new career, Dr. Bailes has run Energy Vanguard, which he founded in 2008.

Laura Nettleton is an architect who has studied low energy solutions since the early 1980’s, when she worked on Passive Solar projects. Her career has been focused on retrofits as she understood early on embodied energy in most existing buildings, is a large number! She completed one of the first LEED projects in Pittsburgh but longed for better energy performance. After she was introduced to Passive House, she served as a champion in the Pittsburgh region and her office, Thoughtful Balance designed one of the first large scale Passive House retrofits in North America.

Katrin Klingenberg is a visionary who has driven adoption of the Phius Standard throughout the past 20 years. Passive building methodology originated in the United States and Canada in the 1970s and was enhanced in Germany in the 1990s. Klingenberg reinvigorated it in the United States in 2003 when she built the first passive house in Champaign-Urbana. Her home sparked considerable interest and she went on to found the non-profit organization Phius (Passive House Institute US), dedicated to making passive building a mainstream best practice.

Gabriela Martin is Program Director at the Illinois Clean Energy Community Foundation (ICECF), where she oversees energy grants, including the Foundation’s net zero programs. She has more than 25 years of experience working in policy, research, analysis, energy modeling, program and product development in the fields of renewable energy, energy efficiency and greenhouse gas emissions across the electric utility, public and non-profit sectors.

Lois’ 32-year career as a practicing architect has focused on sustainability as intrinsic to design aided by the application of green technologies and sustainable planning. As Chief Sustainability Officer for Wight, recently, Lois has led the effort to design five buildings to meet the criteria for Net Zero Energy.
