DGNB criteria "Potable water demand and waste water volume"


Our objective is to maintain the natural water cycle and reduce potable water demand by recycling waste water and using local resources.


Reduction of potable water and waste water demand reduces running costs. In addition, a high level of waste water recycling and the use of local resources (wells, rainwater) helps achieve independence from price fluctuations and availability.

Indicators for evaluation

  1. Potable water demand and waste water volume

  2. External works

  3. Integration into the district infrastructure
