modelling Geo-cooling

edit

Hello folks,

I need to assess the energetic consumption of a building. In this building, the cooling production is provided by geo-cooling: the water is circulated in the borehole fields and thus cooled by heat exchange (passive cooling): There is no heat pump in the cooling loop. The added power needed to meet the cooling loads is then provided by active cooling.

I'm looking to model that on DB/EnergyPlus. Did someone already modelled that system before? Is there any workaround for it?

Thanks in advance,
