[EnergyPlus_Support] Fan System Operation



Hi,

To comply with the item G3.1.2.4 Fan Sytem Operation from ASHRAE 90.1-2007, where the fan needs to operate continuosly whenever spaces are occupied and shall cycled to meet heating and cooling loads during unoccupied hours, I used the AvailabilityManager:NightCycle tool with control type CycleOnControlZone. However checking the annual results, the fan didn't cycle at any time during unnocupied hour. Does anyone know what happened? I have tried use the fan type ON/OFF to comply with the item, but the result was the same. 

Regards,

Fabiano Ferreira
