<br>
ASHRAE 90.1 appendix G states that:<br>
<br>
"Schedules for HVAC fans that provide outdoor air for ventilation shall run continuously whenever spaces are occupied and shall be cycled on and off to meet heating and cooling loads during unoccupied hours."<br>
<br>
Can someone please explain to me how to do this? What type of schedule (1 or 2 schedules, etc.)<br>
<br>
Thank you very much!<br>
<br>
Best,<br>
Omar<br>
