We demonstrate that by employing the correspondence between gauge theories ingeometric and in deconstructed extra dimensions, it is possible to transfer themethods for calculating finite Casimir energy densities in higher dimensions tothe four-dimensional deconstruction setup. By this means, one obtains anunambiguous and well-defined prescription to determine finite vacuum energycontributions of four-dimensional quantum fields which have ahigher-dimensional correspondence. Thereby, large kink masses lead to anexponentially suppressed Casimir effect. For a specific model we hence arriveat a small and positive contribution to the cosmological constant in agreementwith observations.Comment: 38 pages, 5 figures, minor changes in the text, results unchanged, figure added, reference adde
