I'm trying to set the solar and visible absorptance for the roof of a building. Right now, I've deduced I need to loop through the surfaces to find those with an outside boundary condition of outdoors and a surface type of RoofCeiling. Once, I single out these surfaces, how do I set their solar and visible absorptance?

Thanks.
