When designing a new building, which of the following strategies can be implemented to accommodate...

A dual-piping system provides the physical infrastructure necessary to use alternative water sources without mixing them with the potable-water distribution system. LEED v5 recognizes multiple alternative water sources, including reclaimed water, graywater, rainwater, stormwater, condensate, and other recycled sources. Designing separate distribution piping during initial construction makes future conversion substantially easier because nonpotable water can later serve suitable end uses such as toilet flushing or irrigation without extensive demolition and repiping. Individual meters can help measure water consumption but do not provide a distribution pathway for alternative water. A feasibility study can inform planning, but it does not make the building physically ready to integrate another supply. Therefore, Option B is the most effective future-readiness strategy for incorporating alternative water sources.
