1. An air duct system comprising:
a duct segment disposable within a plenum underneath a floor of a building, the duct segment including a pliable tubular wall extending from a first end of the duct segment to a second end of the duct segment, the first end to be coupled to a supply air duct within the plenum; and
a fastener to enable connection of a connection point on an exterior surface of the duct segment adjacent the second end to a portion of the building, the fastener to pull the duct segment, via the connection point at the second end of the duct segment, in a direction opposite the first end of the duct segment thereby placing the duct segment in tension along a length of the duct segment between the first and second ends, the fastener being a single elongate pliable member that includes a first leg and a second leg, both the first and second legs to be angled relative to the length of the duct segment to provide horizontal support to the duct segment in two dimensions.
