Hi All,

Is the RoofVegetation Material in Energy Plus unaffected by shadow calculations? If not, how does one get shadows to affect calculations?

I have setup a relatively simple simulation comparing outdoor surface temperatures of asphalt, concrete and grass using Rhino>Grasshopper>Honeybee>Energyplus.

The grass is represented by the RoofVegetation material. Disregarding discrepancies between the anticipated temperature differences of the materials and those generated by the simulation - a seemingly stranger issue seems to be that, unlike the other materials I have used, the RoofVegetation material is seemingly unaffected by context shade.

Is this a known issue, or perhaps something missing from my script?

Unfortunately I do not have enough points to upload here but you can find an image of the issue and my grasshopper script on the Ladybug forums here: Ladybug thread

Any advice woill be greatly appreciated.
