PURPOSE:To increase ventilation ability of a multi-slory building having a draft, while keeping safety. CONSTITUTION:A ventilation shed 17 is formed just right above the opening 16 on the uppermost floor of a draft 11 and a ventilation louver 18 is installed on the whole wall face of this ventilation shed. Respective brades 20 are retained at the place where the grades are kept by stoppers 23 in the condition usually opened outward by installing the rotary shaft 19 at the position deviated by a specified distance from the center of the width of respective brades 20 of this ventilation louver 18. And further, the deviation is adjusted so that only the ventilation louver 18 at the receiving side of the wind pressure against the wind from a special direction is closed.
