Dear all,
I am currently estimating the occupancy of a mall building. I have determined the occupancy following Appendix 2 default occupancies from LEED.
However, I am confused about how to estimate the daily averages and peak totals for bicycle facilities and indoor water use calculations.
According to the LEED reference guide, regular building occupants and peak visitors are required for bicycle facilities calculation.
In this case, regular building occupants are equivalent to FTE according to the reference guide definition.
Therefore, if I want to estimate the number of long-term bicycle storage I will use the FTE number.
For this exercise retail occupancy ratio applies, 51 m2/employee (0.02 employees/m2 approx) according to Appendix 2. I assume this is a daily average value. Since the mall will have 2x6h shifts on a daily average, and the daily average accounts for all the occupants of a given type for a typical 24-hour day of operation, therefore 0.02 employees/m2 -> 12h, to convert to FTE = 0.02*8/12 = 0.013 FTE/m2.
Am I interpreting something wrongly? how would you recommend doing it? is this approach acceptable?
Thanks

Hi,
Can anyone give me a hint on this?

Hello!
Maybe late, but still. It's wrong approach per my experience. Since it's not a daily average FTE. Per my understanding it's FTE for correct mall operation. So you need X FTE per Appendix 2 for one shift, and X FTE for second shift.
If you are gouing for 2 shifts of 6 hours for 12 hours working day for some of the workers at the mall (I believe administration is working regular 8 hour shift) you need to take into account shifts overlap for for bicycle facilities - i.e. double FTE for workers that works in such schedule: since one shift already arrived while first shift hadn't left at that moment.
In such case I considered 12 hours working day (it's allowed with some limitations by local law) or, if working hours of facility were like from 10 am up to 12 pm - shifts of 8 and 6 hours, that are not completely overlaping (i.e. half of facilities workers are working 6 hours, then are replaced by those, who works 8 hours, second half of facility workers are working 8 hours, and then replaced by those who works 6 hours) - it gave us only 1,5 peak FTE for such workers.
Indoor water use does not require shift overlap accounting - I never met such thing.
