The BS* + Beer Show: Book Club With Martin Holladay

A conversation with the author about building homes in today's climate

Image credit: Travis Brungardt

This episode of the BS* + Beer show features former GBA editor Martin Holladay, along with several of our regular audience members and returning guests Kyle Macht and Carl Seville discussing Martin’s book, Musings of an Energy Nerd. There’s talk of the drawbacks of Passive House certification, the move toward renewable energy, the urgency of the climate crisis, the “fatal flaw” of the net-zero energy movement, the feasibility of carbon-negative builds, vapor barriers (of course!), and the importance of loving your house design.

Enjoy the show!

Join us on September 2 from 6 to 7:30 p.m. EST for a conversation with Dan Edelman and Christie Mahaffey. For this episode we will put away the BS and focus on beer for a change. Dan will show us his home-brew setup and Christie will talk about Foundation Brewing in Portland, Maine, which she and her husband Joel own and run. According to Mike Maines, “Christie makes one of the very best beers in Portland, which has a lot of good beer.” If hops are your thing, this one’s for you!


Dan Edelman has worked in the building industry for 20-plus years—beginning as a project manager of large commercial projects and now working primarily with residential designers, builders, and contractors. Dan has been with Rockwool for almost 10 years and works with builders, contractors, and architects nationwide, offering solutions to common issues with the building envelope. Dan has been a part of many high-performance home builds and recently turned a code-driven home into a more energy-efficient build with proper installation of the building envelope components.

Christie Mahaffey is founder and owner of Foundation Brewing Company in Portland, Maine. With a background in biology, materials science, and engineering, Christie leverages her scientific acumen to oversee the brewery’s quality control program. In her role, Christie spearheads Foundation’s efforts to understand both the biology of their beer and the techniques necessary to ensure excellence and consistency. Christie also serves on the board of the QC2 Lab at the University of Southern Maine; the program provides discounted lab services to Maine breweries, ultimately supporting the fast-growing industry and bolstering Maine’s reputation as a leader in microbrewery innovation.

    Is BS + Beer available as a podcast; if not, is there some reason why? I try to avoid YouTube as much as possible, so some other options for downloading and listening in would be great.

      Hi Aaron, yes, you can find an audio-only version on Apple Podcasts and Spotify. The only downside there is not being able to see visual presentations, which many guests share.

    This was an excellent episode. Martin Holladay is pure gold and he's fundamentally correct when he essentially says the best way to get close to carbon neutrality is to stay in your current home and buy less stuff (aka stop building new homes). Alas we are humans and we owe ourselves to something better than just existing.

    I also think Martin is spot on with regards to code inspections or course there's a lot of lag on state/county level with regards to code adoption. One quip though is that I think a free market (which btw we've never really had in the US) would be key component of a solution to building better and getting consumers invested in the energy performance of the homes they choose to live in. For example the energy market in the US is highly regulated and subsidized (Solar, Wind, Fossil Fuels). If energy prices were not regulated, homeowners would have an incentive to insulate themselves from price volatility. This incentive would translate into demand for better performing homes. In the long run cost will always be important. Altruism will not cut it in the long run.
