Duct energy efficiency includes four different topics: duct airflow, duct air leakage, duct location, and duct insulation. If we want to improve duct energy efficiency, we need to proceed in a logical and planned way so that we don’t accomplish one task and discover that we have hindered another important task. The video will give you an overview and the reading assignments in materials will fortify what you learned in the video. A short quiz follows the video and reading assignments.
