Welcome to the first official “Ask The Experts” edition of Build. Matt answers real questions from builders, architects, and fans of the show. This episode covers a wide range of high-performance building topics that every pro should consider. 

First, Matt breaks down unvented attic assemblies in LA’s dry climate, offering insulation recommendations and best practices for staying code-compliant without overcomplicating the build. Then, he dives into the hot topic of venting dryers in airtight homes—exploring options like heat pump dryers and makeup air systems.

Next up, a thoughtful discussion on HVAC design in energy-efficient, all-electric homes, especially when working with contractors who size systems by square footage instead of proper Manual J calculations. Matt shares practical advice for builders working in high desert climates and explains the value of multi-stage and VRF equipment. Finally, he addresses one of the most overlooked but crucial areas of waterproofing: sill pans. From stainless steel to PVC, Matt discusses materials, back dam design, and how to prevent rust or water intrusion under doors.
