Adding paint layer to wall


I wish to define an exterior wall element using the HBOpaqueMaterial component and then adding the different wall layers to the HBOpaqueConstruction component. I was wondering if I could add some sort of paint to the exterior wall as a light colored paint would reflect the sun falling on it and hence reduce the heat absorbed by the wall. As such, I could find a layer for paint in HBSeachMaterials. Is there a workaround for this?

You should use the Material’s Solar Absorptance field to set the values based on the color of the wall.

See here for more information about the field.
