[EnergyPlus_Support] Problem modelling geothermal heat pumps

Hello all.

For a project in my university, i have to model a geothermal heat pump in a building, in order to lower heating and cooling loads.

I simulated the building at first, 4 zones, each with a fancoil (heating and cooling) connected to a hot boiler and a chiller. Up to this point everything is working fine.

When i try to model a pump in that system, whatever the case, there seems to be no effect in the capacity of the boiler and the chiller. I've tried water to water, water to air, nothing works.

Maybe i am missing some point in all this. Can anyone care to explain what the strategy should be in order to achieve lower loads?

Thanks, Michael.
