LEED V4 BD+C (NC) project,

Case A: Project#1-A Building, the building roof and ground recovery rainwater (inside boundary) are stored in the rainwater recovery pool outside the scope of the project (outside boundary of A Building). Then this rainwater in the recovery pool is processed and sent to A Building for outdoor planting and watering and indoor toilet and urinal flushing. Can this part of water (rainwater recovery at inside boundary, store at outside boundary) be used as a water reduction calculation for the A Building “Indoor Water Use Reduction Calculator and Outdoor Water Use Reduction Calculator” use of recovery water instead of potable water in this project?

Case B: We have two new buildings ( A Building and B Building) which will apply LEED V4 BD+C (NC) green building certification for each. The roof and floor recovery rainwater of A Building and B Building will be stored in the one rainwater recovery pool outside the two building projects. The rainwater in the rainwater recovery pool is treated and sent to the A Building and B Building for each outdoor planting and indoor toilets and urinal flushing.

Can this part of water (rainwater recovery at inside boundary, store at outside boundary) be used as a water reduction calculation for the A Building and B Building “Indoor Water Use Reduction Calculator and Outdoor Water Use Reduction Calculator” use of recovery water instead of potable water in this project?
