Dear all,
I encountered a seemingly easy warning about shading fins that took me too much time without finding a solution. I use the example file of energy+ "4ZoneWithShading_Simple_1" which has 2 side fins and an overhang at two of the existing windows. I keep the geometry, etc as it is, but I add a reflectance value (0.4) (ShadingProperty:Reflectance) for the existing fins (at the original file reflectance for the fins wasn't defined). I change also the Solar Distribution from "FullExterior" to "FullExteriorWithReflections" and I get the following warning:
** Warning ** ShadingProperty:Reflectance="ZN001:WALL001:SHADE003", invalid specification
** ~~~ ** .. not found Shading Surface Name="ZN001:WALL001:SHADE003".
** Warning ** ShadingProperty:Reflectance="ZN002:WALL002:SHADE002", invalid specification
** ~~~ ** .. not found Shading Surface Name="ZN002:WALL002:SHADE002".
It doesn't find the fins surfaces although they exist and are already defined. The problem occurs only when the Solar Distribution is set to a choice that contains "....withReflections". I have the same problem with another model of a project with different geometry. I tested both models (my project and the e+ example file) in two different machines (1. pc-windows xp-EnergyPlus-Windows-32 8.1.0.009, 2.Macbook pro-Windows 7 through Parallels-EnergyPlus-Windows-32 8.1.0.009) but the problem remains.
Any advice will be really appreciated,
Catherine
