Hello everyone, I'm working on a campus project that has 2 shifts with 12 hours of work per shift (day shift from 6:30 A.M till 6:30 P.M) and (night shift from 6:30 P.M till 6:30 A.M).
As per the reference guide, In water use reduction credit the dormitory's Residents are considered regular building occupants.
Dormitories Residents/(2 shifts as described above)
We have 492 person/shift
So Residents= 492 ?
Factory FTE /(2 shifts as described above)
FTE= 115 employees x 12 hrs /8 = 173
or I should take this equation FTE employees = (Σ all employee hours) / 8
FTE = ((115 person +115 person )*12 hrs/8)
FTE =345
What is the proper way to calculate the FTE in my case? which number should I use for the water use reduction credit?

I'm not sure I can answer this, but can at least ask a few clarifying questions. When I had a complex occupancy, I determined all my proposed breakdowns (like you have) and had our LEED Coach confirm that our assumptions were correct before moving further with the calcs.
For the dorms, I find it odd that a "resident" would only be there for 12 hours? Are the residents you list there facilities workers that service the dorms in that 12-hour period, or are they actually utilizing the dorm spaces? I think of a dorm as more like a hotel room or short-term living quarters, which seems atypical for a 12-hour situation.
Also, where in the Ref Guide do you see that residents should be considered FTE? There is a Further Explanation section I see under the Prereq that addresses this occupancy type and treats residents (including those in dormatories) separately from FTEs. The fixture types in the dorm spaces may also be considered as residential, which has different fixture baselines in some cases.
