[Bldg-sim] Base case question

Maybe someone can answer this for me:

“Using ASHRAE 90.1-1999 at the reference standard, what is the HVAC system
for the baseline building if the proposed building is a ground-source heat
pump with radiant heating and cooling?  In Figure 11.4.3, the standard
indicates that System 6 should be used.  System 6 is listed as a
water-source heat pump with direct expansion for cooling and electric heat
pump and boiler for heating.  Is System 6 distributed water-source heat
pumps with a boiler for heat and a fluid cooler for cooling?  Or is it a
ground-source heat pump with a boiler for peak demand and domestic hot
water?”

Thanks.
