We are working on a residential apartment project. There will be independent split units in each flat/dwelling unit. Is there anyway we can get the energy consumption of each flat/dwelling unit separately.

As @mdahlhausen alluded to, there is no built-in EnergyPlus capability for this. You have to disaggregate the outputs by requesting several Output:Variable objects.

However, an alternative would be to model each building unit as a separate EnergyPlus model, using adiabatic surfaces as appropriate. Then there would be no work required to get the energy consumption of each building unit separately. This of course works best if each unit has individual heating, cooling, and hot water systems.

Add the 'Zone Lights Electric Energy' and 'Zone Electric Equipment Electric Energy' Output:Variable objects to your model. If your HVAC system and domestic hot water systems are per-unit, you can make output variables for these objects and record them for each zone. Otherwise if they are served by a central system you'll need to allocate energy use by system load or some other means.
