Peter is a Certified Passive House Consultant. He is the only cPHc in the Northwest who is also a mechanical engineer and as such, can provide exactly the kind of system design input we need on our more complicated Passivhaus projects.

Rob Harrison

Job Titles:
  • Principal
I have over forty years of experience as a design professional, including more than thirty-three years as principal of my own firm. I grew up in a small town in northeastern Ohio and studied architecture at the University of Toronto. From my first project onward, my school work centered on sustainable design. My thesis (with Alberto Perez-Gomez) was inspired by my summer in Seattle in 1978. Titled "The Return of the Seasons", it was a landscape art project in High Park in Toronto that explored ways of connecting architecture with the cycle of the seasons. After graduation from University of Toronto in 1979 I moved to New York City and for the first five years there pursued parallel careers in architecture and music. I worked as a draftsperson for Buckminster Fuller and Isamu Noguchi, for residential architect Alfredo DeVido, and recorded and performed music with Philip Beesley, Glenn Branca, Sussan Deyhim, and Christian Marclay among others. In 1984 I opened my own design office. My practice in New York included high-end residential interiors and commercial office renovations. I returned to Seattle in 1990 to pursue work in line with my values. In 1992 I opened my own office again, dedicated exclusively to green architecture. A co-founder of the Northwest EcoBuilding Guild in 1992, I was executive editor of the Guild's journal EcoBuilding Times from 1993 through 1999. I was a board member of the Pike Market Child Care Center 1992-1996, and on the board of Worldchanging 2010-2012. I have facilitated workshops on green design at Building with Value '93 and '96, Celebration of Community, and for permit reviewers at King County DDES, given talks for University of Washington students and the City of Seattle rainwater conference as well as for members of American Society of Interior Designers, American Institute of Architects, Master Builder Association of King and Snohomish Counties, Voluntary Simplicity Association, Seattle Tilth, King County Master Recyclers and Northwest EcoBuilding Guild chapters in Seattle, Portland and Olympia. In 2009 I became one of the first 100 certified Passive House consultants in the United States. With Passive House Northwest colleagues I have given presentations on Passivhaus for the City of Seattle's Green Team, City Council Central Staff, the Coast Guard and for Representative Jim McDermott, as well as a number of local architecture firms.

Robin McKennon Thaler

Job Titles:
  • Seattle WA / Member, US Green Building Council
Mayfly Engineering is a small, woman-owned civil engineering firm specializing in green civil strategies. A LEED accredited professional engineer, Robin's unique natural resource background (a prior degree in forestry) brings an important focus on low-impact design to all of the projects to which she contributes. Robin is known for her creative design approach and solid technical base. She is often asked to participate in value engineering studies and design charrettes for both public agencies and private clients. Robin has provided project management and design for dozens of site design projects and consultation and documentation for more than twenty LEED projects. These projects include Cascade Playground-winner of the 2005 Washington State ACEC Gold Award for Social, Economic, and Sustainable Design Considerations-and The South Lake Union Discovery Center; where the pervious paver parking lot, bio-swale infiltration systems, rain gardens, and demonstration green streets replaced the need for conventional detention. Robin also provided site related LEED consultation for Washington State's Certified GOLD Tumwater Office Building. Though we have yet to officially work on a project together, I have been impressed with the depth of Robin's knowledge and enthusiasm on the project proposals we have pursued.
