Method of venting heat from homes

In a building having a roof and at least one environmental space separated from the roof by at least a ceiling and an attic-like space between the roof and the ceiling, apparatus for causing heated air from the upper portions of the room to be vented from the building, comprising:

• a siphon duct member extending between the ceiling and upper portions of the attic-like space, the siphon duct member being opened at lower and upper ends, the lower end of the siphon duct member communicating with the upper portions of the room;
• means for defining a draft channel within the attic-like space, the upper end of the siphon duct member extending into the draft channel and communicating with the interior thereof to discharge air from the room into the draft channel;
• vent means for causing a flow of air through the draft channel from and to wherein the vent means comprise:
• a soffit vent formed in a lower portion of the roof and communicating the interior of the attic-like space with ambient, the soffit vent channeling a flow of ambient air into the attic-like space and subsequently into the draft channel;
• and,
• a ridge vent formed in an upper portion of the roof and communicating the interior of the draft channel with ambient, flow of air from the soffit vent passing through the draft channel and out of the building through the ridge vent.
