   #16: 50 Years of Building Better with Joe Lstiburek

   Get ready for a masterclass in building science filled with hilarious anecdotes, blunt truths, and profound wisdom. In this episode, Matt Copeland sits down with the legendary Dr. Joe Lstiburek, a founding principal of Building Science Corporation and an icon in the industry. Dr. Joe shares his unconventional journey from aspiring aerospace engineer to a leading voice in building physics, a path forged by on-site labor, getting fired, and not being afraid to tell a home-building legend he had no idea how to build. Listen in as Dr. Joe explains the comical and surprisingly arbitrary origins of fundamental industry standards, like the 50 Pascal blower door test. He argues why "stupid should hurt" and how disasters, litigation, and pain are the most effective drivers of change in construction. From the problems with modern materials like OSB ("the spam of wood") to the critical importance of water management and the next big fight in indoor air quality, this conversation is an essential listen for architects, builders, engineers, and anyone who wants to understand why buildings fail—and how to build them right. Guest Bio JOSEPH LSTIBUREK, B.A.Sc., M.Eng., Ph.D., P.Eng., is a principal of Building Science Corporation and an ASHRAE Fellow.  Dr. Lstiburek received an undergraduate degree in Mechanical Engineering from the University of Toronto, a masters degree in Civil Engineering from the University of Toronto and a doctorate in Building Science Engineering from the University of Toronto. The Wall Street Journal refers to him as “the dean of North American building science”.  When he is not in buildings he drinks red French wine and drives fast German sports cars – but never at the same time.

   Bonus: The Four Barriers in a Contemporary Context

   When it comes to moisture control, what you don’t know can definitely hurt you—and your building. In a time of evolving building codes and increasingly complex facade systems, moisture management demands a sophisticated integration of building science and design.This presentation reveals essential strategies for creating resilient exterior wall assemblies by understanding the four barriers—water, vapor, air, and thermal—within the context of 21st century building demands.We’ll explore specific design considerations for managing moisture as it relates to each individual barrier, as well as actionable QA/QC measures that can be implemented for both new construction and existing buildings.About the Presenter: Carmen PrantilA graduate of the University of Minnesota – Twin Cities with a degree in Building Science and Technology, Carmen has more than survived her share of snowy winters. Her academic background laid the foundation for a deep understanding of building design and environmental challenges that come with cold climates.Now Boston-based (yes, more cold), Carmen brings innovative solutions to her role at Copeland Building Envelope Consulting. She balances her professional precision with her passion for an active lifestyle and off-grid adventures. Outside of the office, you can find her training for CrossFit, exploring the Northeast rail trails on two wheels, or hiking in the White Mountains.
