Matt Risinger welcomes Kristof Irwin of Positive Energy for a deep discussion on the relationship between HVAC design, moisture management, and high-performance construction. Irwin explains how modern homes require a systems-based approach, where airtight enclosures, ventilation, and properly sized mechanical equipment all work together to improve comfort and indoor air quality. The conversation also covers humidity control, energy modeling, and the growing need for testing and verification as building standards evolve. Matt and Kristof discuss how builders, architects, and HVAC professionals coordinate early in the design phase to avoid performance issues later in construction.
