Sam Myers is joined by Dan and John from CEDA 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.

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.

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 one time service.
