Dashiel, a final-year Electronic Engineering and Information Engineering student at Imperial, explains the engine sizes ducts using airflow from the system and equal friction per the CIB and SE Guide B, selects real DW-144 duct sizes, checks pressure drop on the worst run to ensure the fan duty is correct, and outputs the connected duct network between air terminals in Revit. He shows the tool working on a simple seven-room office with a corridor and an AHU. He then reruns the design after adding an obstacle beam, and the ducts automatically route around it, avoiding the beam entirely.</description></oembed>
