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 seal…

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 …

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? And then, I would …

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 res…

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-terminat…

Despite how consistently and relentlessly the boys have dissed ICFs, this episode takes ICFs seriously and fairly (or as best as Jake, Steve, and Pete are capable of...). Pete's Resource(s) 1. "Costs & Benefits of Insulating Concrete Forms for Residential Construction" (https://www.huduser.gov/publications/pdf/icfbenefit.pdf): A bit dated but still…

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. Pete's Resource(s): 1. FPL Deck Guide: https://www.fpl.…

Space conditioning loads can be managed by building professionals through building enclosure and mechanical system efficiency--easy-peasy. But what about the loads determined by occupants and their behavior: domestic hot water, appliance, lighting and plug loads? The boys load up to tackle all kinds of issues and loads connecting energy efficiency …

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…

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…

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)…

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…

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, g…

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 Univer…

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 intentiona…

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 therm…
