  The Commercial Testing Gap

  Aug 12, 202659 min

  Sam Myers is joined by Dan and John from CETA for a live Flow Lab conversation about what happens when weatherization diagnostics move into light commercial buildings. Using a troubled firehouse as the main case study, they break down how high humidity, sick occupants, failed HVAC fixes, and a missing air barrier all pointed back to the same problem. The episode covers multi-fan blower door testing, commercial airtightness metrics, pressure uniformity, smart membranes, QA/QC smoke testing, and why HVAC equipment cannot fix an open envelope. Listeners will hear how weatherization agencies and building performance pros can use the skills they already have to solve bigger buildings, create new revenue, and stop treating commercial diagnostics like a mystery.

  Why Pressure Testing Beats Guessing

  Jun 12, 202638 min

  Sam Myers is joined by Lee Canegaly from Retrotec’s tech support and dev team, along with Michael and Greg, to talk about what happens when blower door testing moves beyond code compliance and into industrial rooms, fire suppression systems, and strange building failures. The episode gets into enclosure integrity, blast-proof shelters, server rooms, and why field testing beats guessing every time. Michael and Greg share stories from refineries, cigar bars, crawlspaces, and humid homes, showing how air leakage can affect safety, comfort, and millions of dollars in protected equipment.

  Find the Pathway, Fix the Problem

  May 13, 202655 minS0

  <p>Ben Walker and Sam Myers sit down with Brantley May to talk indoor air quality investigations, building forensics, and why you need both a contaminant and a pathway for a real problem. Brantley explains how blower doors, duct testing, and pressure diagnostics help prove where mold, smoke, dust, and odors actually enter a home. They also go over common misses from standard inspections, plus why better ventilation can be worth the energy tradeoff when health is on the line. If you want your houses to breathe right, share this with someone who still treats a blower door like a...

  Stop Guessing Start Testing

  Apr 15, 202652 minS2

  <p>Ben Walker and Sam Myers sit down with Jake Bruton to talk blower door testing, airtightness, and why data beats opinions every time. Jake explains why he tests multiple times during a build, what leak paths still surprise teams, and how those checks reduce risk and callbacks. They also get into vetting HVAC contractors for low load homes and why buy-in matters more than bravado. If you are serious about building better, share this with a builder who still “just knows” it’s tight.</p><p>Show Notes:<br/>00:00 Data Over Opinions<br/>00:59 Three Test Strategy<br/>03:09 When To Test<b...

  Building The Future HVAC Workforce

  Mar 18, 202638 minS2

  <p>Ben Walker and Sam Myers sit down with Xavier Walter of the Building Performance Association to talk about the workforce gap, why HVAC contractors need building science partners, and where the industry is headed next. They get into apprenticeship and workforce development, how weatherization and HVAC can work together, and why callbacks drop when contractors solve the whole problem. Plus, a quick run-through of what to expect at the BPA National Conference in Columbus, April 13–16.  <br/><br/>And if you want to attend, use this link to register: <b>http://nhpc26.org/flow-lab</b></p><p>Use code <b>NHP...
