  We consider the ground state energy of scalar massive field in the spacetime
of a pointlike global monopole. Using zeta function regularization method we
obtain the heat kernel coefficients for this system. We show that the
coefficient $B_1$ contains additional contribution due to the non-trivial
topological structure of the spacetime. Taking into account the heat kernel
coefficients we obtain that the ground state energy of the scalar field is
zero. We also discuss our result using dimensional considerations.
