You can assign a different frequency for output variables than the simulation. Variables can use “hourly”, for example, even if the simulation uses 6 steps per hour. The last field “Schedule Name” appears to allow selecting a very specific range of values, although have not used it. Also, you can use “RunPeriod” or “Hourly” to get a smaller number of values. From: EnergyPlus_Support@xxxxxxxxxxxxxxx [mailto:EnergyPlus_Support@xxxxxxxxxxxxxxx] Ok. I have a simulation of 52560 timesteps. In "output:variable", when I put the variable, and the reporting frecuency of timestep, I obtain a ".csv" file with 52560 rows. I need to see only one row in ".csv" file. I think if i put a specific schedule of this timestep, the result will be a ".csv" file with this value. But i dont know how to do it.
