Subject: RE: [EnergyPlus_Support] zone load simulation with energy plus
If you display hourly output values, the displayed number is averaged over the previous hour period.
In a cold night, the system is heading the zone in the morning just before the sun comes out. The sun beam entering the building through a window can increase the temperature very fast, at 440W per square meter of window area. When this is happinging during the same reporting hour period, it is normal to see heating and cooling values at the same time.
With shorter timestep reporting periods, you may see the values not displayed in the same period.
I am not sure of the exact variable name. Zone heating rate and zone cooling rate display the heating and cooling power required to heat and cool the zone to the theremsstat set temperature. They are in the .rdd file.

Subject: [EnergyPlus_Support] zone load simulation with energy plus
Hello,
I want to use energy plus to simulate the thermal load of a multiple zone building.
Currently in the HVAC templates, I built a HVAVtemplate:Thermostat and five HVAVtemplate:zone:IdealLoadAirSystem for five zones.
SO in the output:variable, which variable describes the thermal load of each zone?
Is that the Ideal loads air heating rate/ ideal loads air cooling rate? I am not sure whether I should use this, since I found that even for an individual zone, there could be a heating rate and cooling rate at the same time at certain time period.
Thank you very much!
