Energy model pump baseline for ultra tall buildings

Has anyone run up against issues in energy modelling for spaces in ultra tall buildings? LEED baseline in IES 6x lower than the actual for the building. While the building efficiency is ultimately good and achieved LEED Gold BD+C, we are struggling to get our model to make sense - the pump Btus are 6x higher than a 2010 ASHRAE 90.1 baseline. We know that this is because they are pumping to over 1000 feet vertically, but can't find an exemption anywhere or reference for how this might be better understood. Would really appreciate any feedback, especially from those who have done CI projects in a CTBUH building.
