It's a very simple construction which only has one level, 6 rooms. I have no idea why it always failed. In 'Results and Compare' section, it says 'The energy simulation failed'.
However, on GBS, I can see 248 runs have been made, no error is noticed. Also, the fuel in column 'Total Annual energy' is 0 and carbon emission is N/A, which is impossible.
I can send my rta file if that helps.
