Re: [EnergyPlus_Support] Limitations in Number of Zones?



Thanks Oscar. 

I have a question. Did you modeled them as 500 unique zones or, let's say 25 unique zones with floor multiplier of 20?

Hi,
 
I modeled a project with more than 500 thermal zones. The problem its not energy plus, its open studio. To open my model in open studio it will be necessary 2 hours.....!!! So I can recommended you to simplify your model.

Dear Vladimir,

 

While I do not know the exact number (I think itâ??s a lot higher than 200), I doubt that you really want to model that many zones without a very good reason.  Keep in mind that zoning in EnergyPlus, or any modeling program, should be selected because of considerations for function and scheduling, solar exposure, and HVAC system type, not by room configuration.

Does anybody know and have the experience with the maximum number of zones(ballpark) that you can model with Energy Plus.

I did all of my energy modeling with DOE2.1E and that number in DOE2.1E is somewhere from 100 up to 200 depending on the number different system types and in general the complexity of the energy model input.

Thank you in advance,

Vladimir.
