RE: [EnergyPlus_Support] About the output:variable
Hello,
Sorry, you are right. I started to compare data after:
Warmuping Up
Warmuping Up
Warmuping Up
So can you tell me how can I do to start to compare data after
Warmuping Up {1}
Warmuping Up {2}
Warmuping Up {3}
Thank you!
Ying Yan

Hello,
True, I started to compare data when the program began to "Starting Simulation...". Thank you.

I can't tell from your screen if the data is for the warmup period or
the actual environment.
When you run the simulation you should see:
Many lines of information, then
Warmuping Up {1}
Warmuping Up {2}
Warmuping Up {3}
Starting Simulation...
When the program gets to "Starting Simulaiton..." is when you want to
start comparing data.
