Alexander Gard-Murray is the Executive Director of Passive House Massachusetts, a nonprofit that educates advocates and supports passive house building in the Commonwealth. With a background in political science and climate policy, Alexander was pulled into building decarbonization via a Twitter thread.

In this episode, we talk about how Massachusetts has become a shining example of adopting passive house and passive building standards, why we need to think longer term when calculating the ROI of building efficiency, and how passive house buildings benefit everyone, whether or not they live or work in one.

Naomi Beal is the Executive Director and a founding member of passivhausMaine, which opened an ambitious new public-facing workshop, showcase, training, and office space in downtown Freeport in 2025.

In this episode, we talk about the decisions behind the new space, the importance of outreach at the local, community, and school level, and an interesting community-based project they hosted to help low-income households lower their energy bills in the wintertime.

Valentine Gomez is the founder of Gomex Engineering and the first certified passive house designer on PEI (Prince Edward Island, Canada's island province). He thinks of Passivhaus as a kind of gateway rabbit hole, which has since led him down further, deeper rabbit holes, focused on healthy building materials, and including his achieving a Living Future accreditation.

In this episode, we talk about Valentine's experience as the first to bring Passivhaus to a new area, his tactics for getting people on board, and why he thinks municipalities are missing a trick by not choosing to build publicly owned buildings to the Passivhaus standard.

Lindsey Love came to Passivhaus via bio-based materials, marrying the two and comfortably working with both. With her new venture, Regenerative Building Solutions, Lindsey steps further into the role of teacher, advisor, and consultant, helping people incorporate more natural materials into their own high-performance projects.

In this episode, we talk about the gap between builders and architects when it comes to Passivhaus (and what needs to be done to fill it), the power of curriculum-based affordable housing projects, how and when to let your inner building science nerd out, and much more.

Dr. Wolfgang Feist is a professor and mathematical physicist who began his career in quantum mechanics and astronomy before becoming interested in energy efficiency in buildings and moving into engineering, which led him to the late Bo Adamson, a Swedish building scientist and professor at Lund University. Together, they co-originated and developed the Passivhaus standard in the late 1980s, with Dr. Feist going on to found the Passivhaus-Institut (PHI) in 1996, in Darmstadt, Germany.

In this episode, we talk about Dr. Feist's experience living in the world's first (and therefore longest-existing) certified Passivhaus, the changes in attitude and relevance he's seen over the years, the misconceptions that block people from embracing Passivhaus, what Passivhaus really is, and the best way he sees for the movement to continue to spread.

Tessa Bradley is the principal architect and CEO of the Artisans Group Architecture and Planning Company, a woman-owned, woman-led firm based in the Pacific Northwest of the United States. Tessa was in the second round of PHIUS trainings, and Artisan's Group did the second certified Passive House in Washington State ... so they've been in this space for almost as long as anyone in the US.

In this episode, we discuss the difficulties of talking about passivhaus and high-performance building in a way that's not so terribly unsexy, the value of having a place to show clients—whether it's a past client's home, an office or an apartment they can spend time in—and the importance of knowing when going for certification will be beneficial for all involved.

He is one of the team of friends who bring the Humid Climate Conference to life, looking forward to the sixth installment this coming Spring (2026).

In this episode, we talk about the nuances of applying the Passivhaus standard to hot, humid climates, cooling vs. dehumidification, the many motivations of the clients he's worked with on passive house projects, and the real sense of camaraderie and friendship that exists within the passive house community.

In this episode, we talk about Michael's experience building the first straw bale house in his town (Oakville, ON), 20 years ago, the importance of supporting and including anyone interested in getting into the field of better-performing homes, not letting dogmatic viewpoints exclude people, and his optimism for the future of the Passive House industry.
