Hello, I am a beginner with openstudio/E+ and sketchup I am using the HVAC templates. When I run a simulation my cooling consumption is different between "EnergyConsumptionDistrictHeatingCoolingMonthly" (10779 kWh) and "ZoneCoolingSummaryMonthly" (9127 kWh)

How can we explain this ? Thank you for your help

I suppose that it could be connected to efficiency of the cooling system. You take from District Cooling 10779 kWh, but you supplied to zone only 9127 kWh, becouse of 85% efficiency.

Why not but I dont see anywhere the input for the efficiency. I already tried to check with the 'Site to Source Energy Conversion Factors' (1.056), but it didnt match
