It's a really difficult problem for a beginner ! Best way in my opinion is to use Open Studio interface to describe all your loops.
For your AHU, you can use a Controller:OutdoorAir with HeatExchanger:AirTo:Air and Fans.
For the air source HP I think the best object will be this one : https://github.com/NREL/EnergyPlus/pull/5584.
But for now you can try the HeatPump:WaterHeater (I had lots of problems with it...).
Else you can try the ChillerHeaterPerformance:Electric:EIR (EnergyPlus only).
If you want more information, we'll need more details.
