The parameters and topologies used by Modeller for calculating the objective function are CHARMM files, so the energy is nominally in kcal/mol. However, the energy is strongly dependent on your choice of restraints, and should at best be considered a 'pseudo energy'; for example, it's probably unwise to directly compare the energies of two different proteins.
