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.
