ZoneHVAC:IdealLoadsAirSystem results in zero under source electricty cooling

I have just started working with honeybee. I had not selected any HVAC system for my model. However, the energy simulation CSV result file shows value under End Uses- district cooling (KWh) as a non- null value. Further, even if I consider that the default HVAC system is set to ideal air load system (is it so?), why is the value for electricity corresponding to district cooling under end uses zero?

Please suggest!

The ZoneHVAC:IdealLoadsAirSystem always reports to the Discrict Cooling and Heating report. Since this is an ideal air system there is no electricity or fuel use, only energy transfer.
