You can model the effect of reflectance by changing the surface properties of the relevant constructions. You can edit the reflectance of floors, walls, ceilings etc by editing the material properties assigned to the material in the relevant layer in the construction. Note that light reflectance is 1 minus absorptance. This is explained in the Help file and also I think in the (free constructions) DesignBuilder tutorial.
