Harvested rainwater from green roof and collected steam condensate are reused as graywater
in the building and for truck washing.
Rainwater (roof run-off) and graywater

One way to make this transition is through a graywater
In fact, reusing your graywater
may be the only way to keep your lawn and garden healthy without taking more than your fair share of the community's precious freshwater reserves.

" drains to their yards, "which carries health risks." And if watering did not continue, trees might die and home foundations would crack.
Strategies focusing on applying ICT to external environments and components of buildings, such as "B1 Intelligent vegetal wall system", "D2 Inductive shutter", "D3 Solar photoelectric glass", "D10 Solar-tracking light-guide plates", "D11 Smart roof light-guide system", and "H1 Intelligent graywater
recycling system", are classified as "Attractive" attributes.
