Abstract: An apparatus and methodology for abating fungi in a building supported on a ground surface and having an upper enclosed living space and a lower enclosed space beneath the upper enclosed space and proximate or beneath the ground. The apparatus includes a blower positioned in the lower enclosed space and having an air inlet and an air exhaust; a plurality of intake conduits having inlet ends adapted to open in the lower enclosed space proximate a lower boundary of that space and outlet ends connected to the inlet of the blower; a plurality of exhaust conduits having inlet ends connected to the exhaust of the blower and outlet ends positioned exteriorly of the building; and a plurality of ultraviolet lamps positioned at spaced locations in the lower enclosed space and establishing germicidal killing zones intercepting and cleansing air moving from the lower enclosed space into the inlet ends of the intake conduits.
