Revision history [back]
I've always interpreted G3.1.2.5 (G3.1.2.4 in 90.1-2007) to mean "HVAC Operation Schedule" is set to the occupancy schedule, and "Use Night Cycle" set to "Cycle on Full System if Heating or Cooling Required".
This is how the openstudio-standards gem sets up baseline systems, in this method. As explained in the comments above the def, the code assumes 'occupied' for hours when the people occupancy schedule value is greater than 0.15.
