I ran simulation with HVACTemplate:Zone:IdealLoadsAirSystem.
When I checked peak cooling load in html output, it is around 2100kW(pic1).
I wanted to check this cooling load to whole building in hourly data.
I checked hourly data for Zone Ideal Loads Zone Total Cooling Rate summing up for all zones.(pic2)
However, value is much smaller than 2100kW.
I wonder are there any hourly data item which is equivalent to annual peak cooling load in pic1?

Hi Katsuya. Have you tried only running the annual simulation and excluding the sizing periods from your run period? I could be wrong, but I would then expect the Cooling Maximum Value to be pulled from your annual simulation (and match the peak from your plot) instead of from the design day.

I agree with @jbatt. We know that the way of E+ to calculate is in dynamical way which means it will start from your running period. And the temp. internal load will affect the real states of the building when it calculate till your short running period. How can you get the annual/peak cooling value? From report? I did E+V8.7, but it does not have.
