Building Science Unfiltered: Dr. Joe Lstiburek Tells It Like It Is

Описание: Dr. Joe Lstiburek (Building Science Corporation) delivers a no-filter talk on what actually makes buildings durable, sustainable, and resilient. From “fire first, structure second, energy last” to real-world lessons from Grenfell Tower, hurricanes, floods, and wildfires—this is a masterclass in avoiding the hidden risks of “efficiency” when it compromises safety and moisture control. Biggest takeaway: it’s okay for buildings to get wet… if they can dry.
