I am doing a single zone case with Ideal Load Air system in EnergyPlus. After the calculation the sum of loads gives Annual value of cooling [kWh] as

Cooling:EnergyTransfer 18465.24
(kWh) Cooling:EnergyTransfer:Zone:TEST ROOM 18465.24 (kWh)

This is sum of envelope + internal gains + infiltration

But the cooling value under District cooling is Cooling Annual Value [kWh]
DistrictCooling:Facility 21569.35
DistrictCooling:HVAC 21569.35
Cooling:DistrictCooling 21569.35

I have tried many cases but there always is a difference in the district cooling value and the sum of loads. Can some one help me understand this difference?
