102 - Q&A: 2024 #3 - A funky Arkansas roof & a heat pump water heater install in Montana

2/15/2024
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 like to apologize for Steve and his: "A polar bear walks into a bar..." Resource(s): 1. Venting hip roofs - https://inspectapedia.com/ventilation/Hard_to_Vent_Roofs.php 2.

2/1/2024
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.

99 - Site Hydrology? Steve puts on his hydrologic engineer hat; Jake & Pete add their thinking caps...

1/4/2024
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...). Pete's Resource(s): 1. Pete has a series of YouTube video clips on building assessment, with the first 3 dealing with water: groundwater, site surface water, and building load. Take a look... https://www.youtube.com/playlist?list=PL2pL2KVsx9SCcqQBdEjbiYfI3AouC1CoL 2. Superior Walls foundation system: https://www.superiorwalls.com 3.

92 - Q&A with Adult Supervision: OSB Structural Panels

9/21/2023
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...). Pete's Resource(s): 1. Huber Technical Support: https://www.huberwood.com/technical-support 2. Solid Panel System - https://bbe.umn.edu/research/perfect-wall-building-and-delivery-system

90 - "Good Fellows" Tools We Use Every Day In Our Work

8/17/2023
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. NOTE: You have to listen to the entire podcast to understand the Good Fellows reference...but it is worth the wait. Has Pete seen it yet? He is still not sure... Pete's Resource(s): 1.

88 - What makes a PSA tape "self-terminating?" Wingnuts want to know...

7/20/2023
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! Pete's Resource(s): 1. Pete's blogs on Wingnut PSA Tape Testing - Pete wrote over a half dozen blogs on his tape testing. Go to www.buildinggreen.com and search using the term "wingnut tape." 2.

87 - Residential Water Efficiency - Can we save water AND get high performance?

7/4/2023
Our homes use way more water than you think they need to. The boys dive deep into water efficiency and performance, from toilets to showerheads to hot water recirc systems. Pete's Resource(s): 1. EPA Water Sense: https://www.epa.gov/watersense 2. 2016 AWWA Residential End Uses of Water - https://www.awwa.org/Portals/0/AWWA/ETS/Resources/WaterConservationResidential_End_Uses_of_Water.pdf 3.

86 - ICFs: Insulating Concrete Forms, for real...

6/20/2023
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 useful given that the PATH program (Partnership for Advancing Technology in Housing) is a decent backdrop for a fair analysis of this building technology. 2. "Air Leakage of Insulated Concrete Form Houses" (https://dspace.mit.edu/handle/1721.1/72627): Interesting that this energy modeling research reports less than significant air leakage advantage of ICFs compared to wood frame single-family houses.

85 - Q&A June 2023

6/8/2023
Four Cool Questions: 1 - Airtight Drywall Approach from Aussie Sean; 2 - Continuous Insulation (moving from below-grade to above-grade walls) from UBIP buddy Ian; 3 - Frost Protected Shallow Foundations (anonymous) ; 4 - Roof penetrations from Jake's IG buddy Jeff Pete's Resource(s): 1.

"Which Penetrations Cause Roof Damage?" - https://www.energyvanguard.com/blog/which-roof-penetrations-cause-water-damage/ NOTE/CORRECTION: Pete got one of his units of measure wrong when stating the standard for an airtight building material. He stated "per meter.." (linear) when the correct metric is "per meter SQUARED..." (area) (See https://www.wrmeadows.com/air-barriers/technical-bulletin-standards-explained-astm-e-2178-standard-test-method-air-permeance-building-materials/)

84 - Control layers on Trial

5/25/2023
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?

Duration:00:32:16

83 - All Decked Out - From Frame to Decking to Railings and Stairs

5/11/2023
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.fs.usda.gov/documnts/pdf1997/falk97d.pdf (dated, yes, but seminal and it's written by an FPL great: BoB Falk) 2.
