At the same time, opening and closing units are embedded into the top to form a natural ventilation system, which works in conjunction with the ventilation windows in the outer wall to provide air to the entire factory. The facility was designed as a prototype environmentally conscious factory and incorporates a variety of environmental technologies, such as the use of low-e glass in the apertures, newly developed air-balanced natural ventilation windows, cool tubes, and the aforementioned combined ventilation units and skylights. These features enabled the facility to achieve the CASBEE A Rank for environmental design.
