Hierarchical approaches are the best means to compute global
illumination solutions with finite elements for scenes of high
complexity. Most of these methods are based on Hierarchical
Radiosity and on its idea of a local refiner, which decides about
the level of interaction looking at a single pair of sender and
receiver at a moment. Such local refiners are easy to implement, but
the neglect of global properties of the entire solution often
focuses the computation on details, which are not visible anymore
in the final solution.

In this paper we propose an extension for \mbox{Hierarchical}
Radiosity which introduces the concept of global refinement. This
method can be used to better focus the computations on only those
details, which are of interest for the global solution.
