[EnergyPlus_Support] current limitations in building energy modeling and simulation





Hello Community,

Again, I am coming to you for input in my efforts to make EnergyPlus run faster.  

As Nathaniel Jones suggested, I would like to consider not just the current bottlenecks in EnergyPlus simulations, which are ran from models generated by designers considering the limitations of the software and its capabilities; I would like to know where you would like to get more detailed, precise or accurate data from a simulation run, but accept lesser data in the interest of getting your job finished in a limited amount of time.

To boil it down, I'll ask my question this way: if you could choose one area in EnergyPlus to speed up, what would it be?  Another way of putting it: where would you like more detail in your models, but you simplify in order to reduce simulation execution time?

Many thanks for your help and Happy New Year --
