NC-2009 PIf3:Occupant and Usage Data

LEED v2009 NC Total Daily Occupancy - Help Please!

I have a residential dormitory project with some questions on Table Plf3-3 Total Daily Occupancy. A majority of the building is residential, with a lower level Lobby/Lounge area (Reception and Offices), an unconditioned future retail space (empty shell space currently) and a classroom. 1. How do I calculate peak and daily average transients? We don't have a furniture layout so I can't count seats. 2. Do I include the future retail space transients, even though the space will be empty and unconditioned for an undetermined amount of time? If I do include it, how are those transients calculated? Thanks in advance for any help!

This should've been posted under COMPLEX OCCUPANCY, SORRY. I also have a multi-credit dilemma with ‘complex occupancy’ for LEED NC v3. After spending a good deal of time trying to find information related to non-standard occupancy, daily and annual patterns, per PIF3 I’ve come up with some, but inconclusive solutions. Our project is a National Guard Readiness center. Can someone please help? Perhaps to verify if our calcs makes sense and if anyone has any similar experiences. (I've found several in V2.2 but none in the context of v3.)I would so much appreciate it! Real Life Occupancy: 291 Building Operation Days - 16 full time soldiers, 5 day weeks for admin, recruiting and training prep. - 319 Soldiers training 1 weekend per month and 14 days during the Summer. - 20 Transients Per week (4 per day average) My calculations equate to: Peak Occupants = 319 since transients will not be present during weekends or the 14 day summer training. Peak Transients = 4 – A rare situation that 4 transients will be in the building at any given time, but possible. Total Building Users at Peak Moment: 319 for the same reason as Peak Occupants. FTE Occupants (and this is where I get really confused in the context of this project.) FTE (based on a standard 8-hour occupancy period) during the regularly occurring moment with the highest volume of full-time and part-time occupants. – If taken literally, the highest volume of full/part time people is 319, (there are no part-time occupants) This number doesn’t accurately reflect building annual usage at all. (Linked to SSc4.2, SSc4.3, SSc4.4 & WEp1) It’s only 36 days per year where 319 will be in the building. WEp1/c3 – EAp2/c1 and others are based on annual consumption. The only true FTE is 16. SSc4.2-Bike Racks also wouldn’t make sense placing 16 racks on site. But I believe I can make a compelling argument that trainees come from all over the state and it’s only the 16 full time soldiers that would consider using bikes. What do you think? Daily average transients - students/visitors: Note: Equals the daily average calculated on a yearly basis. Linked to WEp1. = 4 Daily average transients - retail customers/residents = 0 Total building users as a daily average: Equals the sum of FTE and transients expressed as an annualized daily average. = 57 Calculations for this number comes from - (261 Weekdays minus 6 holiday days) x (16 FTE+ 4 Transients) = 5100 Person Days PLUS (12 months x2 days[weekends]+2) x 319=11,484 person days 5100+11484 person days ÷ 291 Operation Days = 56.989 Thank you for your time.
