We investigate the effect of the noncommutativity of space on a many-particle system composed of locally interacting non-relativistic fermions at zero temperature. We calculate the first-order energy shift of the system up to the second order in noncommutativity parameter to demonstrate that the noncommutativity of space lifts the degeneracy of the model, by interpreting the noncommutativity parameter as a new reference temperature.
