Innovative Wall Technologies for Commercial Buildings

This Envelope Technology Research Team webinar focused on wall technologies. Exterior walls are the major components of the building envelope. By being a barrier between the interior and the exterior environments, walls need to have features that minimize the energy losses while maintaining durability. Each year, about 1.5 quads of energy is lost through walls in commercial buildings in America. Fortunately, there exist wall assemblies that are more energy efficient than traditional solutions. Tapan Patel, from the US Army Corps of Engineers presented on their Fort Drum project using modified atmosphere insulation (MAI) panels. Participants also heard an update on Oak Ridge National Laboratory (ORNL) research on existing walls, cross-laminated timber (CLT), and investigation of a building enclosure performance metric.
