hi all, 

I am doing some research on the LEED v4.1 O+M and I came across some questions regarding this credit. Anyone has any idea about possible answers?

Water efficiency

a)    What is the definition of potable water? Is this annual water consumption only linked to potable water?

b)    How do we calculate the gross floor area without ARC?

c)     How do we calculate Weighted occupancy ? could not find example calculation anywhere

d)    How do we calculate Weighted operating hours? could not find example calculation anywhere

e)    Where can I find the Table 2. Operating hours adjustment factor ?

f)     How do we calculate the operating hours per week to find the adjustment factor?

g)    Where can I find the calculation behind the Water performance score.
