For instance, at the beginning of the 20th century in Europe, to accommodate large-scale cotton weaving factories, the old narrow windows that in the past had been good at keeping out the wetness and cold began to be replaced with larger windows that provided for better circulation of air.
例如十九世紀初期，當歐洲開始出現大量棉花紡織廠的時候，過去防潮防冷、窗戶窄小的房舍，就因應新的需求加大窗戶，以利通風。
