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.
