I'm working on a project pursuing LEED v4 Group, New Construction, with 3 separate buildings in the LEED Group. The design team would like to provide 1 potable water meter that serves all 3 buildings to meet the prerequisite. LEED Campus Guidance is vague and states "No" for the Group approach and describes requirements for irrigation, but not potable water. The only water source for all three buildings is potable water (no reclaimed/rainwater).

Can this prerequisite be achieved with a single water meter for all three buildings, and does anyone have precedent?
