Hey all. Is there a way to input fan BHP, kW, or kW/CFM in OpenStudio/energyplus? When trying to update a Packaged Rooftop VAV supply fan through OpenStudio the only fields i'm seeing are Fan Efficiency, Pressure Rise, and Motor Efficiency.

how can i solve this problem

If you use the Fan:SystemModel object, which is supposed to replace many of the other EnergyPlus fan objects in the future, you can set the Sizing Method to "PowerPerFlow" and then enter the Power per Flow Rate in units of W/m^3.

I think you can not input directly fan BHP, kW or kW/cfm.
