Many CIRs address the issue of FTE to an extent, but it seems there might be multiple strategies for accounting for various occupancies. (Hotels near transit can exclude guest occupants- v2.2 SSc4.2 1/23/09, modifying the FTE to place guests in the transients category - v2.1 SSc4.2 6/20/2008, etc). And many of the referenced CIRs are built up from College Campuses, then Airports, but Hotels still seem a little mysterious.
For FTE it is clear: CIR v2.1 SSc4.2 6/20/2008 and the guest belong in transient calculations.
But would guests count toward a Residential occupancy (same usage rate essentially as a home, i.g. there at morning and night)?
Based on this CIR, guest would only be transient in the correct FTE, right? Whereby certain transient populations can be excluded from the calculations in determining the number of required bike storage spaces and showers.
Ssc4.2 is really about making biking more convenient for full time users, however, in this credit, FTE numbers have an impact on usage and occupancy numbers effect overall end water use (and water reduction).
It seems awkward then to place hotel guests in transient for WEc3.1 as guests are more likely to shower and use water fixtures.
I'm posting this same inquiry in SSc4.2 in regards to FTE numbers for hotel guests.

This should have a preview option. I forget some things.
I'd like to add the question about usage rates as well to this.
The LRG has water use calculations which indicate fixture usage rates based on residential standard calculation methodology presented in the LEED-NC v2.2 Reference Guide, Third Edition on page 142.
So, would guests count toward a Residential occupancy (same usage rate essentially as a home, i.g. there at morning and night)? Unless special conditions exist, projects should assume a 50/50 male/female ratio and an average of 5 fixture uses per day for residential usage.
Any thoughts are appreciated.

I would calculate hotel guests as residents, and yes, they should definitely have an assumed 50/50 male/female usage. This is always true unless there is a very specific and provable reason otherwise, which I can't really foresee for a hotel. You would also have FTEs (hotel employees) and transients (visitors + those who come for events, conferences, etc.) These would all be calculated separately in the WEc3 template. You will have to work with your client and design team to determine how many transients are appropriate based on event spaces and other hotel practices.

Thanks Mara, that's what we suspected after looking thru LRG BD+C (we are analyzing this for NCv2.2). But, still, for SS4.2 should different FTE be applied vs WEc3? As CIR v2.1 SSc4.2 6/20/2008 where the guests belong in transient calculations.
