Innovation Credit Design for Active Occupants - 5% FTE?

We are pursuing Design for Active Occupants for a project, and I'm trying to verify the meaning of 5% of FTE occupants.  "Provide a dedicated or multi-use space to act as an on-site exercise room, which includes a variety of exercise equipment, for use by at least 5% of FTE occupants."  My assumption is that it means a room that at least 5% of FTE occupants can use at the same time.  But it could also mean that at least 5% of FTE occupants have access to this room for use.  What is the common interpretation?
