[BLDG-SIM] Ground source loop Vs Open tower

["Ramana Koti" <ramana.koti@xxxxxxxxx>]

Dear all,

I am modeling a mixed use building (offices + hotel)  with a
ground source loop using water from an aquifer for precooling prior to
using chillers (no open tower). We donot know the aquifer depth below
the ground yet but the theoretical premise for modeling is 350' and the
pump used on the ground source loop would be capable of 1500 gpm with
450' head.

Can anybody, in principle, comment on the energy offset by (not using
open tower + reduction of load on chillers) Vs the pump energy for
sourcing water from an aquifer?

Thanks,
