A continuous fluid conducting medium (20) establishes and maintains an air space (14) and occupies substantially all of the air space (14) between the exterior wythe (12) and the interior wythe (15) of a building wall to provide a drainage and ventilation conduit for removing moisture that enters the wall system. The fluid conducting medium (20) may be made of non-woven polymer textiles. Different grades of the non-woven textile can be installed in a masonry cavity wall (10) air space (14), serve as a non-woven polymer mesh (27) for installation in the weeps at the lowermost level of the wall so that the weeps (28) will not become obstructed, as vent mesh (29) at the uppermost level of the wall. Another grade forms a non-woven mat (68) for installation between the structural wall assembly (98) and the stucco (62) or EIFS (64) in a veneer wall assembly (60).
