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.

How do you transform below-grade full foundations (also variously called pits, cellars, or basements and historically meant to be or tolerated as damp and cool and dark) into true living-conditioned spaces? We say add four continuous control layers, access to daylight and egress, thermal comfort, and good acoustics—make it a place to thrive as well as live (and even escape).

It's funny that Steve, a very nuts-n-bolts guy, hosts this largely philosophical episode. But all three of us agree:

Separate symptoms from causes—It's easy to get distracted or engrossed in symptoms, but the causes lead to solutions.

Solutions come much easier if you first identify the problem(s).

Step back to move forward. It's always tempting to jump on the "obvious" solution, but it pays to understand completely before offering solutions.

This episode's strength is how each of us—architect, builder, building investigator—uses the approach above to improve our jobs.

Who would have thought that our buddy Steve would be more than OK with both off-site building and the homeowner acting as their own General Contractor. But combining Superior Walls for the foundation with Harvest Homes for all of the framing means the GC homeowner is dealing with far fewer trade contractors. Steve, Jake, and Pete walk through the advantages and challenges of offsite building.

Tim Hill of Risinger build--Austin homebuilder for over 40 years--teamed up with Matt some 10+ years ago. Tim details his company's approach to architects, customers, and trades, including featuring building science in ALL aspects of their building company. The conversation aptly starts with the job site trailer carrying a Goodman mobile dehumidification unit parked just outside the build studio to the way in which Risinger build embraces remodeling in no small part because it provides such valuable feedback on how their homes perform over time.

One of the most interesting ways to accomplish a high-performance below-grade wall is with Precast Concrete panels. Both Steve and Pete have worked on projects using Superior Walls, the leading US manufacturer of these panels. Certainly, it is not the least expensive way to do a foundation, but this system has a ton of advantages: it is completely engineered by the manufacturer, no cast footing is needed, and it can be completed in a day (REGARDLESS of the weather…).

1. Actually 3 questions--can you/how do you/should you vent a pyramidal roof with dormers? (PS - I just had to look up the pronunciation of "pyramidal"--I found both pronunciations...).

2. How do I configure for adequate air supply and noise control for a heat pump water heater (HPWH) in a 1400 square foot, tight home in Montana?

The boys INTEND to tackle TWO submitted questions but only manage one: Are open-joint claddings better moisture-managed better than traditional lap claddings? This episode is quite the mix of banter, building science, and building history. And note that the last resource in the list below is a great short video with Joe Lstiburek of Building Science Corporation on open-joint claddings.

Listener Bill B poses this question and the boys run with it for the whole podcast: "Can you share the details and the reasons for installing flangeless windows in different planes of deep wall assemblies?" Lots to consider here in terms of ALL of the control layers and their continuity.

You know the boys get weepy over water pretty easily, but Steve's focus on starting with the site drives this podcast. The site is the context for the building, and broadening to site water management can really take the load off of building assembly water management. This podcast is all about digging deeper into building (sorry, just could not resist...).
