Our building is on a campus (industrial facility where all workers need to make a shower at the end of the worktime) and our building provides restroom facilities with showerheads for all other buildings. So all workers of the campus will use showerheads inside our building. For Indoor Water Use Reduction prerequisite and credit, can we count only of FTE (group 1) of our bulding or must we count also occupants of other buildings using showerheads located in our building (group 2). In this second case must be the group 2 entered in the Indoor Water Use Reduction Calculator as FTE (only 0,1 of occupants will use the showerheads) or as residential (100% of occupants will use the showerheads)?
