Self-sufficient water supply and green roofs

All buildings have a sedum tile roof that forms part of the climate and surface water management systems. With its plants the sedum tile roof also contributes to biological diversity by serving as a habitat for birds and insects.
The sedum tile roof collects approximately 50 percent of all rainwater that falls there while the balance is lead to the area's "water garden". It is also part of the cooling system because as the rainwater evaporates the roof temperature drops causing the indoor temperature to fall. Furthermore, the service life of the underlying roofing paper is doubled because of the protection provided by the sedum tile roof.

REINFORCED GRASS INSTEAD OF ASPHALT
Asphalt, which is commonly used in facilities of this type, has essentially been replaced by gravel, concrete pavement tiles or reinforced grass, i.e. flagstones with openings where grass can grow. This means that rainwater drains in a natural way and does not affect the balance of water in the area.

"WATER GARDEN" RESERV O I R
Surrounding the entire facility are creeks that collect and purify surface water. The streams lead to the facility's "water garden" which levels out the water flow and allows natural purification to occur. The design of the surface water handling system means that run-off is the same as before development and that no water is drained via the public surface water network.
