Different water sources lead to different water quality issues. Eric walks us through: sources of tap water; testing water; appropriate water treatment systems responding to the testing results; and a new water frontier: PFAS in our tap water (Per- and Polyfluoroalkyl substances). Yikes!

Eric Aune would make the perfect Marvel Superhero Plumber. With tank versus Tankless water heaters, multiple small tanks, and on-demand recirc systems, Eric brings real-world insight to all sorts of plumbing technologies and techniques. And of course, Steve closes the episode with a special look to his future.

Eric provides Steve and Jake with a plumber's perspective on almost every residential, domestic hot water system available in the US. Stick around for terms like "cold water sandwich," "air-to-water," "CO2 refrigerant," and "recirc." It's absolutely gripping!

Jake spends time at Virginia Tech with Christine Williamson, a leading building professional who integrates building science and architecture. In her first year as an Assistant Professor of Architecture, Christine applies building science to architecture courses such as Environment and Building Systems I and II. In her own words about her new position,  Christine says, "Architecture education is, I think, a lot closer to more of a fine art program than maybe a lot of people realize. That is something I would like to change." 

Jake springs a pair of UnBuild It questions on Christine: how does ZIP-R work in terms of moisture control and the best way to configure a crawlspace. 

You say Post-Frame, I say Pole Barn or Barndominium...Yikes. The boys beat up on this topic when we move utility-grade agricultural weather-sheltering buildings (pole barns) to fully-conditioned homes. Aesthetic questions aside, there is solid building science to consider here. And speaking of building science, how do we insulate and air seal rim joists in a way that keeps them dry and durable? This topic takes us from spray foam and capillary breaks to ZIP-R and six-sided containment of interior air-permeable cavity insulation. Oh my. And once again, Steve manages to make us giggle with his closing wordplay.

From metal worker to Director of Architecture Risinger Build to home remodeler, Chelsea is all about working on buildings. Instead of a working-man's Architect like our buddy Steve, Chelsea is the quintessential working-woman's Architect. And get this: Steve & Chelsea are about to team-up on a Risinger Build project!

Since the internet makes us all so cozy from LA to Louisiana, it comes as a surprise to even hard-core building pros that many materials and systems simply don't translate from region to region. Local context simply interferes: price, local expertise, local building codes, availability of materials, even just "no one has done it that way here..." BUT, the internet and social media are shaking things up, in some cool but also disruptive ways.

When Steve doesn't show up on time for the podcast, Jake and Pete jump all over the idea of roasting him. But the podcast is mainly about why we love working with the "jamoke." It is about a half-hour of stories about the consummate job-site architect, Steve Baczek, the guy we "can't live with; can't live without him."

Jake & Pete get schooled again on dehumidification by Nikki. 

- Nikki introduces the acronym HVACD to make dehumidification in equal standing with heating, air conditioning and ventilation.

- Great discussion of the differences between portable ("big box") and whole house dehumidifiers.

- Importance of the change in measurement standards for DEHUs from "80/60" (80 degrees F & 60% RH) to "65/60" for portable units & "73/60" for whole house units (more real conditions).

- Jake closes out by "dibbing" "Dehumidifier Graveyard" as a rock band name...

Jake and Pete host good friend Matt Risinger (pretty sure he is “part” of the Build Show...). It starts simple with pre-drywall checklists (you know, like blocking for toilet paper holders...). But boy, it quickly blossoms into a wonderful, wandering discussion of everything from sequencing to quality control to a scopes of work program. Terrific list of resources comes out of this podcast!

Many of us in the building industry turn to Nikki for all questions dehumidification (certainly including this weeks hosts, Jake & Pete). Nikki goes toe to toe with HVAC techs with a degree in communications and that is because she understands that you have to go tech if you are representing technical products such as dehumidifiers. She connects indoor air quality, occupant comfort, and moisture management. Cool discussion of adding the "D" to HVAC: HVACD or HVAC+D. And apologies to all those expecting (forbearing?) Steve's closing humor...

After the boys were done taking jabs at each other, they each take this question and apply it to their fields: building (Jake), designing (Steve), and enclosure review (Pete). Much of the discussion centers on the cost and expectations that both building professionals and clients have or should set with each other. Another central theme is that pulling in expertise early in the design process may seem as though it is more costly. Still, in the long run, it is better to spend a bit upfront and get key input during design rather than costly changes deeper into the build process. Interestingly, the conversation went from cost to trust as a key element of Pre-Construction.

Daniel Glauser is the Executive Project Manager for Risinger Build in Austin, TX. And he really puts his money where his mouth is. This episode focuses on his deep energy retrofit of a 1977 home in Austin, TX, which will be certified per the Phius Core Revive program. And get this: this soup-to-nuts retrofit is being done while he, his wife, 3 kids, 2 dogs, and several cats are living there full-time. This should be a reality TV show, folks. But on the serious side, Daniel shares all kinds of details integrating the original structure, expansion in 3 of 4 directions, continuous control layers, structural integrity, and fully configured and compliant ACCA Manual J/S/D mechanical systems. The only thing missing from the episode: Steve does NOT close out with one of his "jokes...."

This week's podcast is a discussion about slab-less slabs AND some new projects in which Steve & Jake use alternative or innovative foundation materials or systems. The three boys get off on substantial tangents regarding the environmental profile of foundation materials and construction waste management but hold on: there are great resources below for a host of great topics included in this episode.

Steve and his "jamokes" (Jake & Pete) share moments that changed their careers. Especially interesting is that the term jamoke that Steve uses is most often associated with CarTalk host Ray Magliozzi in this quote: "If my brother and I proved one thing, it's that just about any jamoke can host a radio show." Wow, does that nail the three of us and our podcast!

The boys talk all about energy modeling.

Pete, confused? Pete takes the lead on garages and tries hard not to confuse Steve and Jake (not very successfully...). It's all about how garages are "conditioned" (heated, cooled, dehumidified, ventilated, and filtered) and just what uses the garage is designed for in comparison to the expectations homeowners have in terms of their use(s).

Listeners picked up on two places where perhaps Steve and Jake do not agree (can you imagine....?): Face-seal vs. Drained-rough-opening window/door installations and details at sill plates. After considerable "silliness" (that would be Steve's not Pete's pun...), Jake & Steve reconcile these apparent disagreements with lots of UnBuild It love for each other (WHAT???).

Great questions from our listeners!

How do you determine the best insulation levels by climate (with the best being the greatest value)?

Does adding screws (at some point during construction) make sense when using Advantech floor sheathing, adhesive, and ring shank nails?

Client involvement is critical in any building project, but this can be a double-edged sword. We need our clients engaged and to manage their expectations, particularly given how much information/stuff is available online. The boys each give their perspective on the importance and the corralling required for client involvement.
