Disclaimer: I personally do not use Grasshopper, but I use Openstudio.
You might want to try using this Openstudio measure to inject an Energyplus object called OtherEquipment and inject it in your simulation (find more info here).
The object can be used to add a specific load (sensible or latent) to a zone.
