Matt Risinger continues his deep dive into spray foam insulation, part two, sorting the genuine benefits from the marketing hype. He unpacks common myths—claims that foam pays for itself, blocks sound, or solves every building problem—and explains why cavity insulation alone doesn't guarantee air sealing. He covers the real risks of open cell foam in humid attics, addresses whether spray foam is banned in Europe (it isn't, though regulations are tightening), and shares practical hybrid approaches combining closed cell foam with other insulation types for cost and performance balance.  This episode is a continuation of our discussion on spray foam insulation.

This week on Better Buildings for Humans, host Joe Menchefski sits down with Sarah Gudeman, mechanical engineer at BranchPattern, for a thought-provoking conversation about building science, indoor environmental quality, and why truly great buildings are designed around human outcomes—not just mechanical systems. Drawing on her expertise in sustainability, healthy buildings, and building performance, Sarah explains how air quality, thermal comfort, moisture management, daylight, acoustics, and resilience must work together to create spaces where people can genuinely thrive.The discussion explores everything from health-based and value-based sustainability to high-performance building envelopes, HVAC design, Passive House principles, glazing strategies, occupant comfort, and the evolving relationship between architecture and engineering. Sarah also shares why collaboration early in the design process is essential, how resilient buildings provide long-term business value, the hidden impact of bird-friendly design, and why the best engineering solutions often become invisible when they're working exactly as intended.It's an inspiring conversation about rethinking building performance through a human-centered lens—and a reminder that the world's greatest buildings aren't simply energy efficient or technologically advanced. They're the ones that quietly disappear into the background, creating healthy, comfortable, resilient environments that allow people to focus less on the building itself and more on living, learning, and doing their best work every day.More About Sarah GudemanSarah Gudeman is a Mechanical Engineer, Principal, and Practice Lead at BranchPattern, where she focuses on improving building performance through the lens of human health, indoor air quality, and value-driven sustainability.

I was recently reading the May-June, 2026 issue of "Science and Children" a publication of the National Science Teaching Association. In this issue, I read the Science 101 column written by Matt Bobrowsky. It was entitled "Q: How Can I Build Science Literacy for Lifelong Learning (Using Thermal Insulation)?" We can build science literacy by teaching students that science is a process of asking questions, testing ideas, using evidence, and explaining results — skills they will use far beyond the classroom.

Matt Risinger takes a balanced, evidence-based look at spray foam insulation, separating common misconceptions from practical building science. He compares open-cell and closed-cell spray foam, explains where each performs best, and discusses topics including air sealing, vapor control, indoor air quality, installation risks, and long-term durability. Matt also explores how spray foam compares with fiberglass, mineral wool, and other insulation options, while outlining situations where hybrid insulation assemblies make more sense. Rather than promoting or dismissing spray foam, he focuses on proper installation, climate-specific design, and choosing the right insulation strategy for high-performance homes. This episode is presented without a sponsor to provide an unbiased discussion.

In this short episode from the Bry-X stage of the 7th Annual HVACR Training Symposium, Tessa Murry gives a class on building science basics: The House Always Wins! Tessa is a building scientist who works with TEC. Tessa's class is about how the house puts HVAC contractors in difficult situations. When people have indoor air quality or comfort concerns, the HVAC often takes the blame, even if the issue is with the house. There are usually several little home improvement decisions that create unintended consequences and add up. In many cases, when there aren't exhaust fans in kitchens and bathrooms, moisture stays inside and can cause indoor condensation. Air-sealing, adding or removing insulation, replacing windows, replacing furnaces with a different efficiency model, and even moving people in can all affect comfort and air quality. Comfort issues and complaints, such as hot and cold spots, often point to issues with the house, not necessarily just the HVAC system. Pressure boundaries and thermal boundaries in the building envelope need to be aligned, continuous, and consistent for HVAC systems to do their job well, but many houses don't have that. Those boundaries need to be clear between attached spaces like attics or garages. Those spaces create problems with energy efficiency and comfort, and humidity is a problem in some climates. Garages also have fumes we want to keep out of the house.  Heat moves from hot to cold, and air moves when there is a pressure differential. Mechanical equipment and wind can drive pressure differentials. If there is a pressure difference and a hole, there will be air movement. In the winter, cold air sinks and displaces warm air, which rises and creates positive pressure at the top of the house. That air will push through gaps around can lights, vents, and more. When that humid air gets into a cold attic, the moisture will condense on the roof decking surface and cause an ice dam to form. In the summer, hot, humid air comes into the structure. Regardless of the house's issues with air movement, it's on HVAC contractors to make the decisions that put the occupant's health and safety first, including calling the contractors with the knowledge to diagnose the house's problem.   Have a question that you want us to answer on the podcast?

Matt Risinger explores one of the most misunderstood topics in building science: vapor control. Sponsored by Huber Engineered Woods, the episode explains why managing moisture is less about stopping vapor and more about preventing condensation inside building assemblies. Using a replay from the Building Science 101 series with Steve Baczek, Matt breaks down how vapor moves through walls, roofs, and floors, why climate and material selection matter, and how builders can make smarter decisions about vapor retarders and air barriers. The conversation focuses on practical building science principles that improve durability, moisture management, and long-term building performance rather than relying on outdated rules of thumb.

Happy 4th of July Build Show Friends! This week, we're throwing it back to one of the greatest hits of Season 5. Matt will be back next week with an all-new episode. Enjoy! —— Matt goes solo this week to share hard-earned wisdom from his 30-year construction. He outlines three foundational principles that have shaped his success—and helped him recover from serious setbacks. 1. Understand Building Science Matt emphasizes the importance of knowing how climate, materials, and design affect building durability. Lessons from Portland's mold crises taught him that “if it can't dry, it's going to die.” Builders must master rain control and moisture management to prevent failure and reduce liability. 2. Stop Bidding He shares a cautionary tale of a low-bid roofing contractor whose shoddy work and fake insurance cost him over $30,000. Instead of free estimates and competitive bidding, Matt now uses pre-construction agreements to ensure clients are committed—and to get paid for his time. 3. Avoid Debt Matt recounts going hundreds of thousands of dollars into debt during the 2008 recession, even struggling to pay for groceries. He urges builders to stay lean, avoid speculative projects, and budget personally AND professionally. Matt's advice: “Fire Chuck”—his nickname for the debt he couldn't get rid of for years. Matt concludes with a reminder that profit is essential, not shameful. Builders must prioritize long-term sustainability, financial health, and client trust to thrive in a competitive industry.  Thank you to our episode sponsors ROCKWOOL & Pella.

Four listener questions. Four very different building science challenges. One highly technical episode.Steve, Jake, and Pete tackle a collection of building puzzles that span foundations, roofs, wall assemblies, and moisture management. The discussion starts with expansive soils and why successful construction often depends on engineered foundation systems designed to accommodate soil movement. From there, the crew examines attic radiant barriers, where they work best, and why climate matters when evaluating their performance.The conversation then shifts to a cold-climate stucco retrofit involving exterior rigid insulation, reinforcing a core building science principle: prioritize the four control layers in the right order—water first, airtightness second, drying potential third, and thermal control fourth. Finally, they unpack the risks of a “diaper wall” assembly, where moisture-sensitive materials become trapped between low-permeance layers, and discuss how weather protection and airtightness can reduce those risks.A highly technical episode packed with practical problem-solving, building science fundamentals, and real-world application.Pete's Resources:Post-Tension Slabs for Expansive SoilsEvolution of Foundation Design for Expansive SoilsORNL Thermal Performance Evaluation of Attic Radiant Barrier SystemsBuilding America Solution Center – Attic Radiant BarriersEPA Moisture Control GuidanceGBA – Vapor Profiles Help Predict Whether a Wall Can Dry

Matt Risinger sits down with Jordan Smith of Smith House Co. to discuss the evolving role of inspections, permitting, and building codes in custom residential construction. Smith explains how code compliance impacts everything from framing and mechanical systems to scheduling and client expectations, especially as energy codes and inspection requirements become more demanding. The conversation explores the relationship between builders and inspectors, the importance of documentation and communication on site, and how experienced builders navigate gray areas between minimum code standards and higher-performance construction practices. They also touch on regional differences in enforcement, inspection delays, and the challenge of balancing craftsmanship, efficiency, and compliance throughout the building process.  Huge thanks to our episode sponsor, NuvoH2O.

In this episode of the Build Show Podcast, Matt Risinger sits down with Jordan Smith to work through the full spectrum of residential HVAC mechanical systems — from the bare minimum to the over-engineered. The conversation moves quickly from what not to do (single-stage compressors with flex duct in unconditioned attics) to what actually performs: separate air handlers per floor, dedicated dehumidification, and ERV systems for continuous fresh air. For two-story homes, both agree that zone dampers are a dead end and that two independent systems are the only real solution. The middle-ground sweet spot they land on is dual single-stage units paired with at least one dehumidifier and a basic fresh-air intake strategy. A recurring theme is that equipment brand matters far less than installer quality — a well-installed Goodman beats a poorly installed premium unit every time.  Huge thanks to our episode sponsor,  JELD-WEN.

Recorded live at the 7th Annual HVACR Training Symposium, this episode brings together Roman from HVAC School and building science practitioner Brynn for a deep-dive conversation on one of the most pressing challenges in the HVAC industry: how contractors can use building science principles not just to solve problems, but to communicate value and close sales at the kitchen table. With 26 years of industry experience and 15 years of consistently applying building science in his contracting business, Brynn shares the process his team has refined to help homeowners understand their comfort problems — and confidently invest in the right solutions. Central to the conversation is the idea that testing — not guessing — is the foundation of a great HVAC business. Brynn outlines his team's "big three" diagnostic approach: starting with indoor air quality testing, followed by a load calculation using a LIDAR tool, and finishing with a duct evaluation. These three steps give technicians the data they need to tie findings directly to a homeowner's stated concerns. Rather than overwhelming customers with spreadsheets and raw numbers, the goal is to present information in a way that connects with their lived experience — validating that their hot rooms, cold spots, or humidity discomfort are real, measurable problems with real, measurable solutions. Brynn's team can complete a full load calculation in as little as 20 minutes on-site, a capability that routinely impresses homeowners and sets them apart from competitors. The episode also tackles the business case for slowing down. Rather than rushing technicians through six to eight calls a day, Brynn's company reduced daily call volume to two to four, giving technicians time to perform thorough diagnostics. The result? Ticket sales increased, replacement opportunities grew organically, and install callbacks dropped to a remarkable half of one percent, compared to an industry average closer to ten percent. Roman and Brynn agree that adopting building science practices isn't about overhauling your business overnight. The key is to start with one skill — like combustion testing or airflow measurement — master it, embed it in company culture, and build from there. Over time, these small habits compound into a business that delivers on its promises every time. Beyond the technical content, the conversation wraps with a heartfelt discussion about workforce development and the GRIT Foundation, a nonprofit working to reintroduce skilled trades exposure to young people. With shop classes having largely disappeared from schools across the country, Brynn and Roman emphasize the importance of giving children the chance to discover a passion for hands-on work. Brynn's team hosted a GRIT camp in Detroit, and one participant has since enrolled in HVAC college — a reminder that sparking curiosity early can change the trajectory of a young person's life. Contractors interested in Brynn's training programs and building science bootcamps can find more information at HVACTrain.com.

Building science is at the core of high-performance construction, but it takes more than an understanding of psi-values and hygrothermal dynamics to actually get these buildings built. As we see in this episode, having a real-world understanding of materials science, finance, and how people actually work together is yet another component to this line of work. Granted, there's still a lot of building science involved, as emphasized by the clips featuring Ed May and Ben Bogie, but this episode of The Reimagine Edit series of the Passive House Podcast should be a reminder that construction touches loads of academic fields, and that the status of expert will forever be a moving target in an evolving industry.In this episode, host Zack Semke shares selected clips of conversations from the Reimagine Collective. Featured speakers include Ben Bogie, Jesse Hunt, Michael Ingui, Ed May, and Emily Mottram.The Reimagine Edit is a special series of the Passive House Podcast that shares curated insights from our Experts-In-Residence at the Reimagine Buildings Collective, our membership community of building professionals stepping up to tackle climate change.

Mark sits down with Andrew Legge of Havelock Wool for a conversation that starts with sheep and ends in the walls of a healthier home. Andrew shares how a New Zealand idea turned into a fast-growing insulation company in the U.S., why builders are slow to change, and what makes wool such a powerhouse for sound, air quality, and performance. It is smart, surprising, a little crunchy in the best way, and proof that sometimes the best building product has been standing in a pasture the whole time.

Is social media helping the building industry—or hurting it? Matt Risinger joins Jake and Steve as the Three Social Media Amigos to roast Pete, the resident social media skeptic, and unpack what online platforms really mean for builders, architects, and building science pros.The conversation draws a sharp line between the dark side of social media—misinformation, marketing noise, and ego-driven content—and its best potential: real information transfer, community, and better buildings through shared knowledge. It's entertaining, honest, and occasionally brutal (especially for Pete), but it also raises serious questions about how we learn, teach, and influence in a digital world.The takeaway? Social media can either amplify expertise or dilute it. The difference comes down to intent, integrity, and how we use the tools.Pete's Resources:Information Transfer in Social Media (ResearchGate)Matt Risinger – The Build ShowJake BrutonSteve BaczekPete Yost

QUOTES from the episode: "Most building failures aren't mysterious. They're just ignored fundamentals." "If you demand museum-level humidity, you're no longer building a house. You're building a museum." "Moisture meters don't solve problems. They show you patterns. The thinking solves the problem."   In this episode of the Building HVAC Science Podcast, Eric Kaiser is joined by Kohta Ueno, principal and co-owner of Building Science Corporation, for a wide-ranging discussion on building failures, moisture, HVAC, and the practical realities of diagnosing real-world problems. Kohta shares his unconventional path into building science, from small remodeling jobs and a PBS NOVA episode to decades of forensic investigations alongside Joe Lstiburek, one of the field's most influential voices. The conversation quickly moves from origin stories into what really matters: how buildings fail, why those failures are often predictable, and how much cheaper it is to solve problems on paper than after construction.   A major theme is moisture management, especially in high-performance and multifamily buildings. Kohta explains how seemingly small details, like window sill slope, back dams, airflow settings, and interior air seals, routinely separate durable buildings from expensive failures. He also highlights a growing perfect storm in modern construction: oversized HVAC equipment, high ventilation rates, poor commissioning, and limited dehumidification, particularly in smaller units. The result is mold, humidity complaints, and systems that technically run but fail to control moisture.   The episode closes with a practical look at diagnostic tools and methods. Kohta emphasizes pattern recognition over single-point measurements, combining moisture meters, thermal imaging, pressure diagnostics, and blower door testing to understand how air, heat, and moisture actually move through buildings. He encourages listeners to use freely available Building Science Corporation research and Joe Lstiburek's Building Science Insights as foundational resources, reminding the audience that most building failures are not mysterious. They are repeatable, understandable, and avoidable if the fundamentals are respected.   Kohta's LinkedIn: https://www.linkedin.com/in/kohta-ueno-472a4/ Links mentioned in the episode: Our Current HVAC Mess Experts discuss problems with residential HVAC systems as a first step toward defining solutions https://www.greenbuildingadvisor.com/article/our-current-hvac-mess   Proposed Solutions for Residential HVAC Problems Experts suggest ways to improve the quality of residential heating, ventilating, and cooling equipment installations https://www.greenbuildingadvisor.com/article/proposed-solutions-for-the-residential-hvac-industry   A presentation on my investigations of multifamily humidity problems: Multifamily Humidity Control Problems: Muggy Mayhem https://buildingscience.com/sites/default/files/presentation-docs/2021-05-06_nesea_be21_muggy_mayhem_ueno_for_pdf_0.pdf   I have done a presentation on the diagnostic tools I use in my buildings forensic work; here's the slide deck: NESEA BE19 Tools of the Trade for Building Diagnostics March 14, 2019 https://www.buildingscience.com/sites/default/files/2019-03-14_nesea_be19_ueno_tools_trade_diagnostics_for_pdf.pdf 2019-03-14_NESEA_BE19_Ueno_Tools_Trade_Diagnostics.pdf   And here's a YouTube video:   Tools of the Trade for Building Diagnostics with Kohta Ueno https://www.youtube.com/watch?v=kCZIJFXDl9Q&t=2978s&ab_channel=TheBSandBeerShow   The complete rundown of Joe Lstiburek's columns:   https://buildingscience.com/document-search?search_title=&search=&field_doc_topics=All&field_doc_document_type=3&items_per_page=10   And some of the research reports we did under Building America:   https://buildingscience.com/document-search?search_title=&search=&field_doc_topics=All&field_doc_document_type=8&items_per_page=10   This episode was recorded in January 2026.

But health experts isn't necessarily the first thing that comes to mind when a home buyer goes to book a home inspection prior to buying a home. However, what if they could be? Home inspectors see more homes inside and out than almost any profession in the real estate industry second only to realtors. What if we were trained to not only identify structural and major system issues, but also potential environmental health issues? As building science begins to dominate discussions around real estate and residential construction, the way we think about health intersects directly as we continue to learn to view a home as one major system. Air leaks, poor or improper ventilation, and moisture intrusion can all factor into mold growth. Proper site location can affect a home owner's health long before the home even exists. Illness is often the final symptom of factors that have existed long before the human body even knows there's an issue. We already test for radon... so what if we learned to look out for common sense issues that could allow us to not just advocate for home buyers... but also for their long-term health? Cristina Greenfield, of Conscious Healthy Home, has some ideas as to how we can do just that.

Quotes from the Episode: "Good building systems don't start with equipment—they start with a plan and a thoughtful process." "Most comfort problems aren't equipment problems; they're building problems we haven't taken the time to understand." "If even one episode helps someone take the next step in their career, then it's all been worth it." Episode 250 of the Building HVAC Science Podcast flips the script. Instead of Bill Spohn and Eric Kaiser doing the interviewing, TruTech Tools' Senior Marketing Manager Ginny Hebert steps into the host seat to reflect on 250 episodes of conversations about comfort, buildings, and the people who work on them. What follows is an honest, thoughtful look back at what the show has uncovered—not just about HVAC systems, but about how people learn, think, and grow within the industry. Bill and Eric reflect on how their understanding of comfort has evolved, especially regarding concepts such as heat transfer, mean radiant temperature, air sealing, and treating the house as a system rather than a collection of parts. They discuss how many "equipment problems" are actually building or design problems, and why taking time to think—really think—about a problem is often the most valuable (and most overlooked) practice in the trade. The conversation highlights how technology, connected tools, and computing power have improved diagnostics, while also reinforcing that good outcomes still depend on mindset and process. The episode also looks forward. From normalizing system testing and indoor air quality assessments to improving how comfort is predicted and communicated, Bill and Eric share what they hope will become everyday practice over the next decade. Above all, this milestone episode is a thank-you to listeners, guests, and the broader HVAC and building science community—for staying curious, open-minded, and committed to doing better work for the people who live in the buildings we touch.
