[EnergyPlus_Support] ASHRAE 90.1-2007 9.4.1.1 & 9.4.1.2

I'm a little confused about the requirements of this section. 9.4.1.1 gives the option to choose building level light auto shut-off on a schedule basis and then 9.4.1.2 requires auto-off after 30 min. on occupant sensor after the last occupant leaves the room.

How does one model this? I'm using e+ and have no idea if one can apply 2 schedules on the same control in a parent, daughter fashion.

How does one set up a schedule to mimik an occupant sensor, anyway? The occupancy schedule is fractional, so if I use that the program may wait for the fraction to fall to zero, if a fractional schedule type is acceptable (I think I read that it is not).
