In order to come up with the total energy use for the building we had to convert all energy types to a common energy unit, in this case kBTUs, and add the totals.

Is there a typical efficiency or heat gain rate due chilled water distribution and insulation inefficiencies?
Example: A Chiller producing 1000 tons/hr of which 750 tons are used by fan coil units and maybe the rest is lost in distribution heat gain. In this example the efficiency would be...
