Hi Rachael,
I'm not absolutely sure about the FTE calcs in terms of bike racks, but if I had to guess, I would say that the number of bike racks and showers could be based on employee counts.

For lighting controls, there is a CIR dated 3/25/09 that states prison projects can achieve this credit if inmates have controls in their cells for daytime use and the system has override capabilities to turn the lights off at night.

Also, for water fixtures, there is a CIR ruling dated 2/12/07 that references EPAct of 1992 excluding water closet and urinal fixtures installed in prisons.
