Hello All,

I am using EnergyPlus v9.0.1 with BCVTB (v1.6). While running the BCVTB Example with IDF file SmOffPSZ.idf I noticed that the simulation starts at 01/01/2017 for RUNPERIOD1 and subsequent one are on 01/21/2017, 02/10/2017, 03/02/2017 ...

In my IDF file I have RunPeriod object as,

And SimulationControl as,

I am using a weather file for STOCKHOLM_ARLANDA, WeatherFile

Now I don't understand why the simulation starts in the year 2017 and also why it jumps 21 days? I tried reading the InputOutput Reference from EnergyPlus, but it was not clear why this is happening.

The simulation starts in 2017 just because that year matches what you input in the RunPeriod object (01/01/2017 is a Sunday) and you did not specify a year.

The logs that you are seeing jumping 21 days is like a progress bar, not every day is displayed but it is running in the background. The output is shown for the user to see that the simulation is progressing.
