Summary
Matt Risinger sits down with Kristof Irwin of Positive Energy to discuss how mechanical systems, enclosure design, and building science work together in high-performance homes. Irwin explains how HVAC design impacts comfort, humidity control, indoor air quality, and long-term durability, especially in challenging climates. The conversation explores right-sizing equipment, balancing ventilation with airtight construction, and using data-driven testing to verify performance. They also touch on homeowner expectations, evolving energy standards, and the importance of integrating architects, builders, and mechanical designers early in the process.
