[EnergyPlus_Support] Runtime improvements found in v6


I would like to extend a very grateful thank you to the EnergyPlus development team for the improvements made to model run-time found in EnergyPlus v.6

I have a very large project for which the energy model required just over 40 hours of run-time to complete a detailed model in version 5.

I added Output:Diagnostics,CreateMinimalSurfaceVariables; and also changed any parameters that I could to speed up the run-time, and it still took 13 hours in version 5 to complete the run.

I simply transitioned this file into version 6 and the run completed in 2 hours!!!

If you are an energy modeler who has avoided adopting EnergyPlus due to concerns about run-time, I would say that the developers have done a wonderful job of addressing this issue. I have found that, with the most recent version, models can be run in a reasonable amount of time regardless of the complexity of the geometry and/or systems.

Many Thanks,
