I have inherited a model which has the ceiling void modeled as separate spaces as internal voids.
I originally ran the model under SBEM and have a BER of 22.8
As the model has atria and is rather complex APache is required
Running exactly the same model in apachesim i have a BER of 180ish. (excusively caused by an increase in the heating demand)
Since then, I have done some sleuthing and tried taking out aux ventilation encase it had been duplicated and got the BER down to 150. ( I suspect this is not the issue)
Further investigation led me to the conclusion that it is related to the internal voids.
Before I go ahead and spend time merging rooms and changing inner volume representation and ceiling void cavity size.
Has anybody else experienced an issue like this and I am missing something blindingly obvious?
Huge BER in Apache but not in SBEM

If anyone is interested or this may help in the future.
It turned out that macroflo was the culprit. the window opening was set to 21°C and the heating setpoint was 22°C.
So basically the heating was fighting with opening windows and struggling to ever make it up to 22°C.
