I would first question whether you have more than 20k ft2 of non-predominant heating source spaces in order to need systems 7 and 8. Assuming that is the case, I believe you should have a single CHW loop serving both system types and the number of chillers is still determined by the total loop capacity. I can't think of any specific wording in App. G to address this, but if I have other baseline system combinations such as a mix of system 1 and 7, I would have a single CHW loop serving all systems.
