An evaporative cooling system for buildings comprising means to draw air from the building, air ingress means having air permeable pads in an opening in the building, and water supply means to supply water to fogger nozzles which direct a water vapor fog toward the external surface of the pads, thus cooling the air drawn through the pads. The fogger nozzles are connected to interconnected water conduits, one of which is independently operated from the others such that it will only operate in cases of extreme temperature, to insure that the pads will not be oversaturated. Preferably, the water conduits are controlled by a thermostat responsive to the internal building temperature, while the independent conduit is controlled by a second thermostat responsive to the external ambient temperature.
