Through The Details: Lessons Learned from 50 Phius Design Certifications

This session traces the evolution of Passive House detailing over the past decade, highlighting how simplification and improved modeling have made high-performance design more practical and affordable. Drawing from numerous PHIUS-certified projects, it explores how assemblies, air barriers, and thermal details have shifted from complex, custom solutions to streamlined, buildable systems aligned with standard construction practice. Through technical examples and personal reflection as a Certified Passive House Consultant, the presentation illustrates how clarity and simplicity have enhanced—not compromised—performance, paving the way for broader adoption of Passive House principles.
