I'm working in a LEED CS Warehouse:non-refrigerant building, the project is divided in 2 main areas: office and warehouse. The restroom area is accesible for both areas, but within the office we have 3 restrooms, 2 of them only accesible for the office employees and 1 lockable restroom with a single occupancy (the 3 of them with the same fixtures as the rest of the restrooms), should I create a new fixture group for this restrooms? Is there any Reference about hot to choose Public or Private?

Furthermore we are using sensor facuets, this force me to choose public faucets when I'm filling the form.
