Two buildings connected with the same HVAC system

I’m going to model two buildings that are on the same site and are of the same owner. The owner wants to achieve the LEED certification for both. The buildings aren’t attached, i.e. there is no common surface. Four geothermal heat pumps are installed in a building (building A) and are connected with both buildings (building A and building B). They provide both heated water and chilled water. Probably the buildings will be registered separately, i.e. the “Guide for Multiple Buildings and On-Campus Building Projects” won’t be applied. Do you think that applying it would be a better solution? Shall I model two different models? If so, shall the heat pumps be modeled according to “Treatment of District or Campus Thermal Energy in LEED V2 and LEED 2009 – Design & Construction” both for the building B and for the building A?
