Hi everybody,
For speeding up EnergyPlus simulation we think to divide runperiod (1 period of 1 year) into multiple runperiods (12 periods of 1 month) and create corresponding idf files for launching (12) EnergyPlus simulation in parallel. I don't know if someone did already the same thing and if the results would be different compared with the simulation of 1 period of 1 year?
Any idea?
Thanks a lot!

Hi Long, I'm pretty sure that is what the "accelerate" feature does when using the JESS JEPlus EnergyPlus server. You can read more here: https://designbuilder.co.uk/helpv7.0/...
Yes, this is an option in BuildSimHub as well.
Yes, this has been done before, the results will be slightly different because of the hysteresis not captured in the independent simulation runs. The building state at the start of the second 1-month period won't be exactly the same as the ending state of the first 1-month period, etc. But the difference is perhaps an acceptable sacrifice for the speed gain. Suggest doing some tests to evaluate whether the difference is acceptable for your use case.
Thanks a lot for your suggestion!
