Abstract: There is a recent research interest about regular black holes and their role in cosmology concerning the current cosmic acceleration. In this context we evaluate the Misner-Sharp mass of an RG improved black hole, the Koch-Sauressig black hole. Next, we demonstrate that although the mass of cosmologically coupled Koch-Sauressig black holes do not increase as a cubic power of the scale factor, it is possible when they model astrophysical clusters to explain both the cosmic acceleration and the cosmic coincidence problem within a swiss cheese description of the late cosmological era.
