  There has been the suggestion that the cosmological constant as implied by
the dark energy is related to the well-known hierarchy between the Planck
scale, $M_{\rm Pl}$, and the Standard Model scale, $M_{\rm SM}$. Here we
further propose that the same framework that addresses this hierarchy problem
must also address the smallness problem of the cosmological constant.
Specifically, we investigate the minimal supersymmetric (SUSY) extension of the
Randall-Sundrum model where SUSY-breaking is induced on the TeV brane and
transmitted into the bulk. We show that the Casimir energy density of the
system indeed conforms with the observed dark energy scale.
