UnBuild It Podcast

Windows are one of the most confusing—and consequential—components of a high-performance home. In this episode, the crew takes a deep dive into window and glass selection, aiming to make things clear without letting your eyes glaze over.The discussion covers dual-pane versus triple-pane insulated glazing units, IGU numbering conventions, and the relatively new i89 coating—including what it means for thermal performance and condensation risk. They also unpack the difference between center-of-glass values and full-window NFRC performance numbers, and why those distinctions matter when making real design decisions.One gem of a takeaway sums it all up, with Jake quoting Steve: “The windows, the envelope, and the HVAC are one line item.”Pete’s Resources:Cardinal Glass Technical Guide (2025 Version 3.1)BA 0402 “Singing the Blues in the Key of Low-E”A Review of Advanced Architectural Glazing TechnologiesEfficient Window Coverings

A detailed look at smarter HVAC ducting, better airflow, and what it really takes to manage appliance exhaust and makeup air in high-performance homes.The boys dive into the how and why behind HVAC duct layout, register placement, and whole-house airflow. They break down how interior design, enclosure performance, and mechanical systems must coordinate—because ducting isn’t just about energy efficiency. Thermal comfort and indoor air quality matter just as much.They also get into makeup air, kitchen ventilation, and what happens when houses get tighter and appliances get stronger. Lots of building science, lots of clarity, and (of course) a little UBIP chaos.PETE’S RESOURCES:Green Basics – GBA Integrated DesignBuilding America – DuctsBuilding Science “The Perfect HVAC”ACCA Technical ManualsMechanical Kitchen Ventilation StudyMakeup Air Systems Example (Fantech)IQAir Visual Pro Monitor

What does it really take to grow as a young builder today? Jake and Steve bring in Risinger Build’s Managing Partner, Tim Hill, for a fast-paced, experience-packed conversation full of practical advice for builders looking to level up their craft, business, and mindset.Jake and Steve give Pete the boot for this one—and for good reason. Tim joins them to share real-world insights on everything from building capital and managing budgets to client communication, niche-building, and avoiding the projects that drain your time and sanity. Across the episode, there are a “baker’s dozen” takeaways that every young builder needs to hear:Build capital each year.Have honest, direct conversations about budgets.Meet clients in person for budget discussions instead of relying on email.Remember that builder or not, you’re in the customer service business.Cost projects accurately, not optimistically.Use the job you’re on to improve the next one.Market your own work and own your story.Don’t take projects just because you feel you have to.Show clients the cool things happening on-site every day—they care more than you think.Think and act like a building professional, not just a carpenter.Trust your gut and say no to the wrong projects or clients.Find your niche instead of trying to be everything to everybody.Don’t let your business consume your entire life.A ton of wisdom in a single episode—and a must-listen for builders on the rise.

A deep dive into cathedral roof design and insulation strategy. The team compares solid-sawn rafters vs. scissor trusses, smart vapor retarders vs. poly, and discusses optimal roof pitches. You’ll learn when to vent from the topside, from below, or go unvented entirely—and why those choices matter.In the last 10 minutes, the crew unpacks one of building science’s trickiest topics: 6-sided containment of air-permeable insulation—and how it impacts attic R-values and energy performance. PETE'S RESOURCES:1.

Seriously? These 3 clowns are sages? The discussion includes how to select the "right” school. How much should a school include building science compared to learning it on the job? And what about even just the 4 control layers?  And all three of us stand squarely with Steve: if you want to design buildings, get out on the job site first, second, and last over the course of your prep and your years on the job. And then take what you learn at the site to improve the information transfer you accomplish with your drawings!PETE'S RESOURCES:The architecture school Steve went toPete taught for Keene State in building science (briefly)ACSA (Assoc of Collegiate Schools of Architecture): cool resource including a Quiz that leads you to schools that reflect what you want out of your architecture educationNICHE Building Science and Technology Graduate Programs in AmericaBuildingScience Newsletter: sign up by scrolling to the very bottom of their home page
