- Treating wastewater on-site and reuse or inject treated wastewater into the original water supply.
How do green buildings save water?
Green buildings make use of evaporative cooling systems to save on energy. Such systems use water for cooling. Keeping in mind the huge need to conserve water, the water used such cooling towers is non-potable water and the same is not drained out but recycled time and again and reused.

They represent adherence not just to a design principle but also a grander philosophy: if you can’t beat them, join them.
What is alternative water use in a building?
Alternative water use is the amount of water consumed within the boundaries of a building from sustainable water sources not derived from freshwater sources over the course of a year. In a net zero building, the total annual water use should be offset by alternative water in part or completely.
What happens to the wastewater discharged from the building?
All wastewater discharged from the building is treated on-site and returned to the original water source. This graphic shows incoming and outgoing water flows of the building. Potable water is supplied and treated on-site from harvested rainwater.
A net zero water building (or campus) closes the loop on the water system by returning water to the original water source. Wastewater can be treated and recharged. Stormwater can also recharge the original water source through green infrastructure.
