Oita City Hall Green Roof Construction
This example is of using water purification sludge as a base for vegetation in a roof-
top greening project. Figure
10.15
shows the Oita City Hall building; in the image,
the area enclosed by the dashed line is where the vegetation's base material was pro-
duced from the water purification sludge. The whole image shows the grassy area
adjacent to a sandy beach, and birds perching on adjacent trees may spread seeds
from adjacent areas, thus continuing to bring new life to the roof, while also finding
a useful application for waste materials and communicating a positive message of
effective recycling of resources.
