Sounds like an idfeditor limitaion. Just open and edit with a text editor. 650 zones?! Sounds like a stadium. Consider splitting the model up into several building models.

Dear group,
For a huge building model, despite large simplifications, I have around 650 zones and 7000+ surfaces.
The problem is:
I cannot open the idf file in IDF Editor (E+ v8.1), for it gives (Run-time Error '7': Out of memory). Although I still have 2GB free RAM!!
If I remove almost all of HVAC equipment (baseline System-7) from majority of zones, it opens, but when I add HVAC equipment to all zones it doesn't! (using DB v4.2 to export idf file).
The questions are:
1. What are the software limitations?
Is there any fact sheet or a specifications sheet to understand EnergyPlus v8.1 software limitations?
2. How can I surpass this barrier?
Thanks in advance,
Hisham
