Steady flow of Outdoor Fresh Air

Hi, I’m doing some analysis. I have a building model and I want a steady flow of outdoor air. I set this using ZoneVentilation:DesignFlowRate so the zone gets a constant supply of fresh air. Can I achieve the same with AirLoopHVAC:OutdoorAirSystem by specifying a fraction of outdoor air? Any help would be appreciated.

Hi, Hi! I’m doing some analysis. I have a building model and I want a steady flow of outdoor air. I set this defined it using ZoneVentilation:DesignFlowRate and scheduled Always on so the zone gets I’d get a constant supply flow of fresh air. air into the zone.

Can I achieve do the same with thing on the AirLoopHVAC:OutdoorAirSystem side by specifying a fraction of outdoor air? Any help would be appreciated.I want this outdoor air to affect the building’s heating and cooling loads. When I use ZoneVentilation:DesignFlowRate, it does affect the loads—does defining it on the air loop work the same way?
