Also, a power exhaust device (6) is installed at a border (14) between the indoor space (11) and the underfloor space (12) to exhaust air in the indoor space (11) to the underfloor space (12). A building ventilation structure comprises: a ventilation passage (5) which penetrates through an inside of an external wall (2) and communicates the underfloor space (12) with an attic space (13); and an exhaust opening (130) to exhaust the air passing through the ventilation passage (5) out of the building through the attic space (13). |
