PROBLEM TO BE SOLVED: To solve the problem that an air stream running counter to the natural principle of causing warm air to form an ascending flow and cool air to form a descending flow cannot be formed well in a conventional double ventilation house. SOLUTION: An energy saving house of an attic ventilation structure wherein an eaves ventilation port 5b and a ridge ventilation port 5c are connected with an attic ventilation passage 5a includes a ridge neighborhood ventilation passage switching unit 4 enabling switching to an air passage connecting the ventilation passage 5c with an attic space 16 (in a case wherein a ceiling is installed in the uppermost story) or an indoor space 14 (in a case wherein a gradient ceiling is installed in the uppermost story) to introduce air flowing in from the eaves to the attic space 16 or the indoor space 14 and an air passage discharging the air from the attic space 16 or the indoor space 14 through the ridge ventilation port 5c provided in the ridge.
