On north and south side of the winter gardens, there are interconnecting stairs that provide opportunities for physical activity and interactions among employees.
Winter gardens act as the “lungs” of the building; they feature 24-m tall water curtain that will humidify the air during the winter month. The louvers in the south-facing double wall let the fresh air enter the winter garden and via the 280 tensioned mylar ribbons extended from ceiling to floor, the incoming air can be heated by the sun and humidified by the water. During the summer time, this water that goes down the ribbons is chill and can dehumidify the air that enters the atria (Fig. 7.10).
