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

Are you sure that "EnergyConsumptionDistrictHeatingCoolingMonthly" concerns only Cooling? Maybe it is sum of heating and cooling?

For sure, its only cooling because I have not value in the heating line
