Dear Joongham,

The relative energies of the two conformers can just be read off by 
comparing the bond energies from your log or out file.
For all cases the bond energies are calculated with respect to the 
fragments (spherically averaged atoms by default).

So for conformers, the reference energies are the same (sum of the 
atomic energies) and the relative energy between the conformers is the 
same as the difference between the bond energy.

Hope this helps!

Kind regards,
