This Architectural Drawing is plan of ducting layout for office building. This is 5 story office building. Duct means a bodily tube or vessel especially when carrying the secretion of a gland. 2a : a pipe, tube, or channel that conveys a substance. b : a pipe or tubular runway for carrying an electric power line, telephone cables, or other conductors. s the cooled or heated air enters a room, it forces the existing air out into another group of ducts. These ducts transfer this returned air to the return plenum. Then, the returned air is directed outside through a flue or filtered and sent back through the system. Ducts should always be located within the conditioned envelope of the building, ideally within the framing of floors, ceilings and walls, and they should be maintained so air does not leak out of or into them.
