UnBuild It Podcast

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!

PETE'S RESOURCE(S):

- "Just a Couple of Jamokes - A Tribute to Car Talk's Rollicking 40-Year Run" - https://newengland.com/yankee/magazine/just-a-couple-of-jamokes-car-talk/. If you are not familiar with Car Talk (and even if you are), you need to know that these guys are the gold standard for funny and informative recorded conversations on air. Jake, Steve, and I can only hope that we rise to their "jamoke" level of funny-and-informative...

 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).

STAY TUNED on Pete's Resources: Pete promises a brand new resource in one podcast on this topic (a resource he has not written but will!).

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?

NOTE: This is about as dry a resource as we would ever recommend, but it has great technical info on all manner of structural floor sheathing installation, including bond and mechanical fastener performance.

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:

1. Separate symptoms from causes—It's easy to get distracted or engrossed in symptoms, but the causes lead to solutions.
2. Solutions come much easier if you first identify the problem(s).
3. 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.

1. What about whole-house ventilation systems (balanced, exhaust only, supply only) and their impact on pressure balance in homes? And do ERVs/HRVs accommodate pressure imbalances created by things like exhaust fans, stack effect, etc.?

2. Per Steve: to butyl or not to butyl...For areas such as door sills, use butyl sealant or maybe acoustical sealant? We know how fond Steve is of Tremco acoustical sealant (a single-component, non-skinning non-hardening synthetic rubber sealant) so this topic gets the big guy on his horse...

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?

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...).

We have a big announcement this week as we return to our first time having Matt Risinger on the podcast.

Jake and his builder team--Luke Mann, (Rangeline Homes), Shane Durkin (Patriot High Performance Homes), and Jackson Andrews (Jackson Andrews Building + Design)--work through all sorts of cool, key approaches to consider with your trades:

·      Paying subs in 21 days

·      Scheduling a site visit for a new potential sub

·      Pulling subs into the bidding process 

·      Using suppliers to evaluate potential new subs 

·      Trade team kickoff meeting to get everyone on the same page/schedule 

·      Setting up debriefs to keep things going well 

·      Reducing risk with a stronger trade team

Jake takes his builder team--Luke Man, (Rangeline Homes), Shane Durkin (Patriot High-Performance Homes), and Jackson Andrews (Jackson Andrews Building + Design)--through this final topic with questions like:

- Do you want your company to grow? (These guys vary in size from 2 to 16...)

- How do you decide when to hire and who to hire? 

- Are you working in the business or on the business?

- Do you have a company culture that suits your team and clients?

- How do you delegate/empower/"let go" as your company changes or grows?

Luke Mann (Rangeline Homes), Shane Durkin (Patriot High-Performance Homes), and Jackson Andrews (Jackson Andrews Building + Design) work through this topic with host Jake Bruton. Key concepts include carefully distinguishing punch list vs. additional scope of work; covering closeout in project-starting customer expectations document; an extended comparison of builder closeout process to a new car purchase; dealing with "closeout-creep."

This is Q&A with Adult Supervision: Kohta Ueno. Kohta is so efficient we nailed SIX building enclosure questions: Listener Gagan - reconfiguring existing walls with new control layers; Listener Bill: the need for dedicated vent space with vertical metal siding on ICF walls; Listener Michael - rainscreens for roofs instead of walls; Listener Sean - best detail for using mineral wool (exterior continuous rigid insulation) on a roof; Listener Miles - hip roof in Arkansas best practice: vented roof, vented attic, what type of insulation; Pete asks Kohta's cut on ORNL's new BuildingScienceAdvisor.

Guest Reuben Rudisill is Huber's Research, Development, & Innovation engineer, joining Jake & Pete from the Building Science Corporation Summer Symposium in Westford, MA. Jake & Pete know just enough to get in trouble when it comes to structural details of ZIP, ZIP-R, and Advantech Huber OSB panels, so Reuben quite gently sets these guys straight on how high-performance OSB is manufactured and tested, how fasteners are as important as the panels, and what you can and cannot do with each of Huber's panels. The podcast does close out nicely with how important friendships are in the building business world (we could get this "touchy-and-feely" because Steve was "missing" for this podcast...).

Steve calls SketchUp his electronic clay model which he can use with his builder, his enclosure consultant, and his clients. Pete gives up the dirt on WebSoilSurvey, the 1st tool he uses on every project design/spec review. Jake heads home for his favorite tool - his new Aarow Building office. Last but not least: Steve returns with his 2nd favorite tool--the field. Getting out to job sites and seeing his design work play out as a process--no substitute and this tool is key to Pete and Jake as well.

The top leading edge of a PSA tape running horizontally is not weather-lapped or mechanically attached, depending solely on the adhesion of that top edge to the substrate to keep water out of the WRB/PSA tape system. Are ALL PSA tapes in WRB systems self-terminating? Is there a way to quantify the top-edge adhesion that makes the tape self-terminating? The boys go at it over this one!

This week the UBIP takes on the topic of control. Jake tries to convince Peter and Steve that the hierarchy we address the four control layers is wrong. Can Jake turn Peter or Steve to his dark side of ideas? Probably not, but the conversation is still valid. Where do you land?

Lots to consider from frame to finish in terms of materials and connection to main structure. The boys agreed that--for bulk water management--attaching the deck ledger to the main structure should be done either for lateral stability only or with the ledger spaced out from the main structure.

Suzanne from Bozeman asked such a great question it gets a SECOND podcast but this time focusing on how far is too far when remodeling in general (instead of just an addition). Tons of cool issues but here is a "gem" from each of the boys.

STEVE: Consider re-design before adding new design. How well are existing spaces being used? Maybe reconfigure/repurpose as the most efficient remodel?

PETE: EVERY remodeling project should start with a full hygrothermal building assessment.

JAKE: All remodeling projects need to start with aligning client expectations with the custom set of constraints each unique structure brings. Do the best your can/as much as you can to any portion of the building you "touch" as part of the remodel.

Featured in this episode--from Suzanne in Bozeman Montana: When renovating, how far should you take performance improvements, on the whole building, on just part of it, or an addition? What about going from the inside versus the outside? What about dealing with windows? 

The overall UBIP response? Do as much as you can, in as much of the building as you can, WITH the same control layer priorities: water first, air second, thermal last. But boy are there still a lot of questions to dive into.

Window weeps are the drainage system for the Insulated Glazing Unit (IGU), protecting the vulnerable seals that sit at the bottom of the IGU. Do all windows have them/need them? Are they meant to handle interior condensation as well as exterior leaks? Should they drain to the face of the frame (visible) or to the bottom of the window frame (hidden)? Pete remains sad, curious, and even a bit disgruntled at how little our industry seems to address, systematically, window weep systems.

Pete's Resource: Stay Tuned! Weigh In! We are counting on our listeners to help us learn more about this topic. Be ye builder, architect, window manufacturer, or carpenter--set us straight if you know more than we do about weeps!

The BS of BS--the bullshit of building science--is Steve's way of characterizing sound building science gone haywire in totally screwy application. Examples include paralyzing worry over vapor diffusion as a way that buildings get wet, insane levels of exterior insulation in below-grade walls, using only financial payback when comparing double- and triple-pane windows (ignoring thermal comfort and durability). Add in over-insulation of window frames, bans on spray foam, and you have the UBIP combined blood pressure skyrocketing.

Three great questions UBIP-answered: proper insulation of slab-one-grade perimeter and the entire slab; managing moisture at the ridge in unvented roof assemblies; proper detailing of the bottom edge of wall sheathing where it meets the concrete foundation system. Since these three are a bit hard to cover--even for the UBIP boys--with just words, good time to check out Pete's Resources below.

Jake and Pete host retired building scientist/mold expert/pulmonary physician, Nathan Yost. Yes, the older and wiser older brother to Pete. Jake and Pete take full advantage of Steve's absence to get the strongest and most focused discussion with Nathan. Long story short: Nathan connects the building science, the biology, and the medical perspective on mold and its management.

At the heart of this issue is the new acronym, TFF--Temporarily Fully Functional. That would be everyone because no one gets around the loss of function as we age. It's not a question of if but when. How well should our homes support the loss of function? Maybe high-performance homes that are just as "UD-ready" as they are "PV-ready" (UD for Universal Design/PV for Photo-Voltaic)? Jake closes out with a pretty cool UD-tip/technique he recently coined.

No touchy-feely stuff here--this is a hard-core business discussion. Good business means BOTH building professionals and clients listening not simply hearing. Wait, what is the difference between listening and hearing again? Listening describes an intentional activity; you are actively trying to hear and process something. Hearing is not intentional; hearing is something that just happens, whether you wanted to hear it or not.

In this week’s Unbuild It Podcast Jake Bruton is joined by a small group of builders to discuss their Ah Ha moments in their careers. Follow along as Jackson Andrews, Luke Mann, and Shane Durkin chat with this, the first in a multi-part series Jake and the guys filmed. 

Our industry-led improvement of building performance with insulation--completely ass-backward from a building science perspective. Doesn't mean insulation is not important; just means we need to take care of other business first (see the 1st three in this series: water, air, vapor). And just as important as insulation and energy efficiency is thermal comfort, complicating things a bit more. This podcast includes everything from continuous exterior insulation to IR cameras, Big Foot, and Star Trek door technology. Oh, and Pete tells his favorite joke, which of course, Steve hates...

Pete's Resource: Building America Solution Center - best resource for insulation for every US climate, bar none: https://basc.pnnl.gov. Oh, and since we spent so much time on thermal comfort and referenced ASHRAE Standard 55 several times, I can't resist plugging this GBA blog I wrote some time ago: https://www.greenbuildingadvisor.com/article/understanding-and-measuring-mean-radiant-temperature.

Holy Smokes--Steve and Pete agree that vapor control is not about a single layer! While this may be the most technical discussion in the Love/Hate series, it still includes plenty of Jake and Steve building science band names.

Pete Townshend - Let My Love Open The Door

The LOVE--from Pete's nearly romantic relationship with blower doors to Steve's fascination with theatrical fog--and then the HATE--from Jake's intolerance for any builder who does not know what a blower door is to Steve's complete frustration with confused spaces ("You are either inside or outside every space in your buildings--there is no in-between"). Three blowhards just can't shut up about airtightness...

Pete's Resource(s): 

• Blog on Blower Doors
•  "Air Barrier Continuity" 

The first in a series of four episodes on the control layers. This approach is trademarked, WTF, Steve Baczek. Expect to hear about flush modern designs, open-joint claddings, and spray testing. We hope you love and not hate this series...

From the Mongol Horde (an actual rock band but what Jake thought Steve was referring to regarding wall permeability) to the Visual Abacus (a rock band Jake wants to form but Steve's new name for his slider detail climate-tuning wall insulation), wall framing is covered in an entirely unique way in this UnBuildIt podcast. You won't be surprised that the boys approach wall framing from the Control Layer Priority perspective.

Pete's Resource: "Advanced Framing: Using Wood Efficiently From Optimizing Design to Minimizing the Dumpster" 

What the Foch (based on the lead-in quote from Jake)? I honestly was not prepared for how riveting an impromptu discussion of floor framing could be but listeners won't be surprised to hear Jake and Steve blow up the "simple" decision of floor framing systems with issues like: HVAC integration, finished floor materials, air barrier penetrations, fire protection for engineered wood systems, kitchen island stability, lumber yard availability of different floor framing systems. This UnBuildIt podcast will simply floor you...

Pete's Resource: Chapter 5 of the code and specifically, sections R502.2 and R502.8, and on the UnBuildIt YouTube channel the new series from Steve called "Before the Build."

Jake is joined by cohost Tim Uhler and guest Mike Conneely  the guys discuss panelized construction and a very interesting window manufacturer.

In this special extra episode Jake is joined by co-host Tim Uhler and guest Aron Jones from Big Dog construction. Siga day 3 wrap up includes conversations about an amazing trade school as well as a very interesting multi-family development that featured a Zehnder ERV for the entire building, sound dampening techniques and some huge windows from B4.

And yet, in homes, whole-house ventilation is a "brand-new" concept in much of our industry. The boys go through all the whole-house ventilation systems citing pros and cons and their own experiences with different systems in their projects across the board.

This week Jake and is joined by Tim Uhler and Belinda Carr to discuss the second day of of the Switzerland trip. Jake and guests talk pre-fab construction as well as a very high-performance jobsite visit.

This week, Jake is joined by Travis Brungardt to promote the Midwest Building Science Symposium in Kansas City and Chattanooga TN. Go to bsandbeerkc.org to sign up for tickets and enjoy some of the best building science minds in the country talking about their craft.

Holy smokes--so much to consider: the boys range from roof pitch to venting, from color (heat absorption) to texture (water retention), and even planning out plumbing penetrations based on roof cladding layouts (or air admittance vents...). And by the way: this podcast only covered pitched roof claddings--roof membranes on low slope roofs waits for another UnBuildIt day.

Jake is joined by Tim Uhler and Kristopher Mirchandani to discuss the innovation process and manufacturing tour at Siga world headquarters. 

Tons to talk about: roof design (simple roofs for easy water management), materials (advanced framing--trusses vs solid sawn rafters), spacing (16 vs 24 inches), accommodating HVAC equipment, and even planning for PV array load. Even building roofs on the ground and craning them into place like a top hat OR what about SIP roofs (and why)? The boys cover a lot of ground but up in the air...

Pete's Resource: "Advanced Framing: Using Wood Efficiently from Optimizing Design to Minimizing the Dumpster:" 

Steve--the Zen master of deep discussion on all things building--explains how he thinks of these two terms. If you don't integrate, you end up solving during application, be it moving water off the building or transferring structural loads. This approach to designing, specifying, and constructing means the window package is connected to the HVAC system, the roof plan connects entryways to gutters, and a problem popping up on paper won't get better or easier on the job site. Although you might get discouraged with the dubious initial focus on beanie babies, hang in there for some insightful exchanges with Steve, Jake, and Pete.

Jake lays out the three major sound issues in homes--inside/out, room-to-room, sources of noise inside the home. Pete draws analogies between early 1980s airport noise abatement and early air tightness work. Steve, always listening carefully, finally offers how he designs for sound management.

Join us as we learn all about Solar 101 - Part 2 with Dan Shifley of Dogwood Solar out of Columbia, MO.

Description: On his own, Steve blindsides Pete and Jake with this: how important is each of our backgrounds and how does that affect our approach to building?  And how can each of our perspectives be shared to build better buildings?

Pete's Resource: For each of us, what resource has had the greatest impact on your perspective:

- Pete: Bill Rose's Water in Buildings - https://www.greenbuildingadvisor.com/article/water-in-buildings

- Jake: Building Science Corp's website: https://www.buildingscience.com

- Steve: Gary Keller's The ONE Thing - https://www.amazon.com/ONE-Thing-Surprisingly-Extraordinary-Results/dp/1885167776

Funny that we want to both make indoor spaces separate from the nasty outside but also connect to the outdoors when it's peachy. Jake kicks it off admirably by linking air quality to CONTROL (surprise, surprise). This podcast will be one in a bit of a mini-series on the broader topic of Indoor Environmental Quality (including things like thermal comfort and acoustics) and the connected topic of ventilation and its IAQ role.

The Business Challenge - Life is too short to work for every client that comes through your door. Work hard to inform them of how you are different as a high performance building professional--including that you charge more because you are worth more--and then let the chips fall where they may. Because our project relationships are on the long side--anywhere from 3 months to many years--it's important to spend as much time vetting as attracting our clients.

Take Two because we only got to two questions on this podcast: What good are industry labeling programs, like Pretty Good House? And how do you identify high performance building professionals? They are kinda related. You don't want to miss Steve's rant on the 1st question, Jake's cut on the 2nd, and Pete's info resource to wrap up.

Peter's Questionnaire

Steve takes the lead on this podcast and ties innovation to one of his favorite clients. Here are the UBIP Big 3 Innovations: from Jake--Huber's ZIP-R; from Pete--AEROBARRIER; and from Steve--wait for it....Instagram. Bet you did not see that one coming. Steve wraps up this podcast with a listener request: tell us YOUR favorite building industry innovation so we can come back to this cool topic in the future!

Doors--tougher than windows, in terms of what we ask of them and proper installation. The boys talk about everything from deciding on swing/slide/pivot to thermal performance to triple-point hardware. And Steve gets pretty riled up, providing all of us a "door" into his thinking as an architect...

Jack-of-all trades Mark Willie is one of the most interesting folks in our industry. He loves buildings, loves people, and loves to connect the two (check out Mark's Build Small Casitas podcast). Steve and Pete delve deep and sometimes pretty wayward to tease out the real Mark Willie.

This week Jake & Peter are joined by Bob Kelly of Wickright. A long career in the construction industry has taken Bob from high-end woodworking to roofing artist. As the owner of general contracting business in Chicago focussing on low-slope roofs in split face block buildings Bob has developed system solutions for repeat problems. He now owns a materials company that can be found at wickright.com

UBIP LOVES Q&A! This episode is nothing short of far-ranging: passive cooling techniques for hot climates, the need for roofing underlayment underneath ZIP roof sheathing, several details for interior basement insulation, and finding high performance building professionals for different markets. And the best is saved for last: Pete tells a story connecting moisture, modeling, and pornography!

Steve and Jake take the lead describing how they communicate as builder and architect, BOTH of them sounding out the importance of EVERYONE spending quality time at the job site. Pete finally pipes up with a Scopes of Work program he and Steve worked on in the Building America program. All three wrap up with the idea of Balanced Building: run your job sites and your business as high performance operations.

No, Steve, the most challenging is not the one-armed paper hanger. Both HVAC & Insulation contractors need to up their game because their equipment and materials have become so much more advanced and complex. This session covers common HVAC and insulation problems and solutions.

Steve Baczek drives this discussion and he is fit to be tied regarding labels like high performance, sustainable, green--you name it. And he goes after "slackers" in our profession who need to up their game when it comes to building performance. Here is Steve's premise, see what you think: Prioritizing for high performance means put on your big boy pants and meet the needs of your client and the planet. If you can't figure out what those priorities are, find an easier industry to make hay...

What happens when a couple of UnBuild It contributors get invited to Switzerland by Siga to learn about how it’s done across the pond? You’ll have to listen all the way through this one to find out.

From the sun to wood to heat pumps, the UnBuildIt guys get all fired up about heat sources. The discussion ranges over thermal comfort, the importance of building enclosure performance, adding domestic hot water, and even teepees. You had no idea just how informative and entertaining heat sources can be with these guys...

In everyone's career, there is a turning point, a point in time that was "before" and "after." And for many of us, that point involves Building Science Corporation. Come hear some backstory on one of the most powerful and influential building performance companies in North America.

This is the first interview in our new Builder Interview series. Join Jake and Steve as they talk with Chad Gessin of First Dunes about the challenges he faces as a builder on Long Island.

What is affordable housing? The answer is more nuanced than you would think. Tune in this week to hear Steve, Peter, and Jake talk about their idea of affordable housing.

Going Against the Grain - Permanent Wood Foundations

Seriously? Aren't the terms "permanent" and "wood" used together below-grade a contradiction in terms? Turns out that if you honor the four continuous control layers below-grade on a foundation framed with pressure-treated wood, both the science and the construction actually work. Is the margin for error probably tighter than with concrete? Very well could be, but framing below-grade seems to bring more attention to detail, as Pete, Jake, and Steve attest.

Does that home need a floor? Of course. Does it need the assembly you were planning for? Maybe not. In this week’s podcast the crew discusses alternative means of construction that Jake and Steve have executed with great success.

Is it inside or outside? That is the crawl space question to ask. How do we know? How to decide? Tune in for this week’s UnBuild It Podcast to find out everything about crawl spaces.

The boys answer listener submitted questions this week.

It may sound like a vanity move for Jake to talk about all the homes in which he has lived (and it is) but it tells a story about the evolution of residential construction in the USA since 1960. From wood foundations to leaky basements to high performance homes, listen to Pete and Jake walk you through the choices.

You asked, we answered. The boys answer listener submitted questions this week. Don't like the answers? Ask the right questions.

Will Toyota and Honda actually change the building industry? We've been promised pre-fab will change the face of the building industry for 30 years...is it really the future?

A roof assembly can be one of the simplest and most complex parts of a building assembly. In this week’s podcast Steve, Jake, and Peter give an intro to roofs.

Above grade walls are among the most exposed assemblies of a building. They have to act as all four of your control layers and therefore they must be considered. Check out walls 101.

Please excuse the audio issues, we are still learning and growing.

Every home starts with a foundation. Every decision making process about the home should start in the same place. In this episode of the UnBuild It Podcast hosts Steve Baczek, Peter Yost, and Jake Bruton give a fantastic overview of their decision making process and philosophy behind the below grade assemblies of the homes we build.

Guest Travis Brungardt of Catalyst Construction talks building science, his passion for the trades, BS and Beer, and has a special announcement about the Midwest Building Science Symposium.

Guest Clayton DeKorne chats with Jake and Steve about our industry, publishing, and how the internet can get it wrong.

Peter, Jake, & Steve talk window install.

The National Fenestration Rating Council provides a window sticker that informs the buyer, installer, and code official as to what is happening with each window, door, or skylight. What does all of the information on that sticker mean?

How many Red Herrings can you name in the building industry?

Jake is joined by Josh and Cyrus from Havelock Wool. The crew chats about everything to do with wool insulation.

Odorless, tasteless, colorless and potentially deadly: Radon is a soil gas that can end up inside our buildings. But it can be easily managed in new construction and in many areas it is required by code and federal regulation. Jake, Steve, and Pete each bring their perspectives to this podcast on the where, the why, and the how of radon mitigation in both new homes and retrofit.

On this episode of the UnBuild It Podcast Peter and Steve are joined by special guest Paul Springer of AeroBarrier. The discussion ranges from air sealing to air sealing with one classic folk music reference. Tune in to hear and enlightening discussion about the AeroBarrier product and process. It might be right for your next project.

From the International Builders Show, to regional events and even the BSC Summer Symposium, the UnBuildIt team breaks down the benefits of attending these events. It's just as much about connections and camaraderie as it is products and education.

Moisture in our building process can be one of the biggest one time loads on a building. Where does the moisture come from? How do we address this challenge?

Blower doors or sucker doors? What should they really be called? This and other informative questions about the mysterious blower door are answered by Jake, Pete, and Steve in this episode of the UnBuild It Podcast.

With 2020 closing out the UBIP crew decided to record a Q&A podcast and release it as an unscheduled surprise to the listeners. Without your support we wouldn’t be here. Thanks for the support!

When the nerd is away the other hosts will play. In this episode of the UnBuild It Podcast Jake and Steve take advantage of Pete being gone by not even talking about Building Science.

On this episode of the UnBuild It Podcast Jake and Peter welcome Gary Nelson of The Energy Conservancy. You may not know Gary, but you should because you are probably very familiar with his product the Minneapolis Blower Door. Gary shares the story of how he accidentally started TEC and manufacturing blower doors, some good history of the blower door, and some really interesting nerdy stuff about the blower door.

The final episode in the 4 part series, control layers, is about thermal resistance...in other words, an R value.

A big part of what makes a house a home is a sense of place.  High performance is as much about neighborhood as it is structure. You will get a kick out of hearing two building science geeks, Jake and Pete, veering off in this episode to talk context with Jeff Speck, who literally wrote the book(s) on walkable neighborhoods, towns, and cities.

 Jeff Speck offers three reasons why we need walkable places to live: economic, human health, and the health of the planet. Jeff is smart, funny, and wide open for a rambling conversation with Jake and Pete.

 Some inspiring quotes from Jeff to pull you into this episode:

 “The typical household makes 13 one-way trips per day. Now that means that someone isn’t getting home at night!”

 “The automobile should be an instrument of freedom, not a prosthetic device.”

 “Transportation systems beget settlement patterns.”

 “The automobile was the first means of transportation that was not nodal or linear.”

 “Transportation systems beget settlement patterns and once you have a good settlement pattern you can have a better transportation system.”

 “Walk Score works despite the algorithm being crap.”

Every time a home is taken apart something can be learned. Sometimes a flashing detail shows its age, sometimes a lap joint appears right on the surface but takes a turn for the worse. However, sometimes nothing is damaged and just as much can be learned. On this episode the guys discuss different learning experiences across their careers that have reinforced the unbuilding to learn ideas.

Peter and Steve talk building science and building science solutions with Ken Kiefer, NE Regional Sales Rep from Siga. Get in touch with Ken directly here, kenneth.kiefer@siga.swiss

The conversation about control layers continues this week with the UnBuild It Podcast crew talking about Vapor! Learn about smart vapor retarders, what is a grain of water, why Steve doesn’t like to talk about vapor, and the uniformity of vapor loads, all on this episode of the UnBuild It Podcast.

Follow along as they the guys discuss sensitive issues. Pressure sensitive adhesives are everywhere in construction...can we trust them? Do they perform as promised? The guys explain that the ASTM standards are probably not the metric we should use to answer those questions. Real world testing methods are then discussed, as well at Peter’s Wing Nut Testing.

Peter and Jake welcome special guest Allen Sealock, ZIP System Product Director, to disucss building science, wood products and Huber Engineered Woods.

On this weeks episode the conversation about control continues. The conversation about air barriers, air movement, and how it's considered in our buildings is expanded upon by our intrepid trio. They cover what the code says, what it actually means, and what real success looks like.

Jake and Steve welcome special guest Matt Risinger to discuss how building science has affected his business.

What is a rainscreen? What does it do? How big of a gap should it be? What makes the rainscreen ventilated? Why would you need a rainscreen? In this episode the guys attempt to solve these questions and others about rainscreen claddings.

I have no idea who thought to give us each of us a mike and then turn us loose for an episode, but there you have it... Not surprisingly, we wandered all over the place: universal design, high performance design constraints, the lack of building science knowledge across our industry, even "Sticky Business" (how dependent we are on high performance PSA tapes, sealants, and mastics). But you won't want to miss these gems: Jake talks about brotherly love, Steve sees red over client's stuck on cost per sqaure foot, and Pete gets called an old goat for his lack of social media skills. When UnBuildIt goess "Off the Cuff" it's a bit like catching Jake, Steve, and Pete with their pants down, but in a good not scary way...

Steve tries to play architect lifeguard as builder Jake and BS Pete practice their own water management strokes on Steve. It's a hefty podcast moving all the way from design to perimeter drain cleanouts, from roof overhangs to capillary breaks at footings. And this session steers clear away from rainscreens cause that is a whole other upcoming session. And the podcast ends with an a cappella solo by Pete...you don't want to miss that.

Steve Baczek and Peter Yost do some reminiscing with Nathan Yost but also put Nathan to task on indoor air quality, building performance, and the new reality with COVID-19. Super-interesting to get Nathan Yost's unique expertise and perspective. Nathan is a pulminologist and a building scientist having spent time in the medical profession and investigating building failures places him in the perfect place to discuss health and buildings. 

The Gents gather round the mics to continue the discussion on control layers. With water management in the rear view mirror, they are looking forward to air tightness, vapor movement, and thermal protection. With nothing but gentlemen charm and persuasion in this enlightened conversation, you are sure to come away with some favorable opinions to add to your knowledge of building science. The guys do a great job highlighting the areas of concern, prioritizing values, and “unbuilding” the complexities of these three control layers. As always, the guys round off the corners of hard discussion with their gentle banter, and provide some thoughts based on sound building science. Give it a listen, and move a few seats up on the learning curve…

The Gents dive in on Episode three to start the discussion of control layers. They start with identifying the layers, prioritizing them, and then giving their unique take on them. The episode finishes up with a preliminary outline of the “Water Management” layer. Listen in to hear why water management is the key aspect to defining control layers. Water is ALWAYS a hot topic, and the guys certainly don’t take it lightly.

The Gents talk about two big questions: 

1. Why do we build? Yes we know we build homes to house people. But what is the underlying premise that drives how we should be thinking about how we build. Listen in and see what the guys have to say, it’s the conceptual foundation for what we should be doing.
2. What are some problems and concerns about the how the industry goes about business? Coming from three different arenas in the building industry, they each have some very personal views. Listen in to hear them list their concerns and how they think the problems can start being solved for.

Peter Yost, Steve Baczek, and Jake Bruton kick off the inaugural episode of the UnBuild It Podcast by introducing themselves and the ideas behind them starting the UnBuild It Podcast.
