A system for the economic and efficient ventilating, cooling and heating of an enclosed space, such as a room or rooms within a building, through controlled ventilation of room air between an upper hotter building portion and a lower cooler building portion with the portions constituting different temperature zones in the building. The system includes a reversible ceiling fan facility and motorized inlets in the lower building portion and motorized outlets in the upper building portion, the inlets and motorized outlets being formed in the building and communicating with the exterior thereof. Air conditioning facilities are mounted within the building and include specifically an inlet for air to be cooled in the lower cooler building portion and another inlet for air which is above the inlet for the air to be cooled and which is for drawing air from the upper hotter building portion down for use as a heat sink for the condenser of the air conditioning facility and wherein the air conditioning facility includes a cold air discharge specifically disposed in the lower building portions and another exhaust above the lower cooler building portion for exhausting the sink air which had been drawn down from the upper hotter building portion.
