Air-conditioning produced by traditional vapor compression cycle is an energy demanding operation. By using passive cooling methods is it possible to avoid, or at least reduce, the need for vapor compression cooling. A passive radiative cooling method could be a three windowed skylight, filled with a greenhouse gas.

Earlier modeling of such a skylight has shown promising results, and work has now continued with experiments. To produce experimental results a parallel set-up was built that allowed for the testing of different material properties. These results have then in turn been modeled using Comsol 4.2.
