Good Morning,
I’m calculating the number of spaces for bicycles and showers facilities for C&S project > 300.000 sf. The project is a mall, and contemplates have general offices, retail offices, services offices, food-court and a grocery store.
I used appendix 1 of LEED Guide 2009 to estimate the number of gross square feet per occupant,where there is a table that show two columns: one is ‘’Employees’’ and second is ‘’Transients’’ but I have 3 doubts.
1) Do I have to include the FTE Transients in the calculation of spaces for bicycles and shower facilities or just with the FTE Occupants I am complying with the LEED requirements?
2) Transients are part-time employees or are visitors?
3) If I calculate the number of bicycle spaces and shower facilities with the table in appendix 1 for C&S, because I don’t have information about the number of occupants, why in the STEP 2 and STEP 3 of the LEED Guide-2009 show in the equation 6 and 7 ‘’Average Annual Building Users’’?
I though we could use FTE Occupants*0.03 and FTE Occupants*0.005 in order to calculate the number of bicycle spaces and shower facilities
Thank you very much for your help

I can answer the first 2 questions:
Yes, Transients/Visitor do figure into the bicycle space calculations, but not the showers. Be careful with "commercial space"; the default is 0 transients/visitors, but you should make an educated guess about how many there could be, and include them in the calcs.
2- I think of Transients as delivery people, maintenance workers, etc. Visitors are people coming in for meetings, or family/ friends dropping by to see an employee, etc. Part Time employees are not transients; you need to convert them to FTE's. In other words if you have 2 part time workers, each working 4 hours/day, that's 1 FTE.
I'm not sure what you are asking in your 3rd question. Step 2 shows how to determine occupants and transients based on square footage, and Step 3 is simply totaling the numbers from Step 2. Seems completely consistent with Table 2 to me.
Yes,
"For projects larger than 300,000 sf, bicycle storage must be provided for 3% of occupants for the space up to 300,000 sf, then an additional 0.5% for the occupants for the space over 300,000 sf"
However this must be calculated using the "FTE + Peak Transients" number.
For mixed use projects it's probably easiest to use the credits forms do these calcs. You'll need to start with P1f3 and then use those occupancy numbers on the SSc4.2 form.
