Re: [EnergyPlus_Support] Shading fins problem with reflectance

["Linda Lawrie linda@xxxxxxxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

I've got another workaround that will work for you. 
It's a little tricky though == you have to understand this problem in the
code.

First, you will need to edit the IDD, and change 
ShadingProperty:Reflectance,
       \min-fields 3
       \memo If this object is not defined
for a shading surface the default values
       \memo listed in following fields
will be used in the solar reflection calculation.
  A1,  \field Shading Surface Name
       \required-field
       \type object-list
       \object-list
AllShadingSurfNames
add
        \retaincase

to this field.

Then, you will also need to change your shadingproperty:reflectance
objects:

ShadingProperty:Reflectance,
    Zn001:Wall001:Shade003,  !- Shading Surface
Name
   
0.4,                    
!- Diffuse Solar Reflectance of Unglazed Part of Shading Surface
   
0.4;                    
!- Diffuse Visible Reflectance of Unglazed Part of Shading
Surface

to:
ShadingProperty:Reflectance,
    Zn001:Wall001:Shade003 Left,  !- Shading Surface
Name
   
0.4,                    
!- Diffuse Solar Reflectance of Unglazed Part of Shading Surface
   
0.4;                    
!- Diffuse Visible Reflectance of Unglazed Part of Shading
Surface

ShadingProperty:Reflectance,
    ZN001:WALL001:SHADE003 Left,  !- Shading Surface
Name
   
0.4,                    
!- Diffuse Solar Reflectance of Unglazed Part of Shading Surface
   
0.4;                    
!- Diffuse Visible Reflectance of Unglazed Part of Shading
Surface

note that the first part of the surface name will need to be in ALL CAPS
and then add the Left and Right

Note that the software also makes mirror objects of each of these
surfaces:
Mir-ZN002:WALL002:SHADE002 Left

I don't know if you need to add reflectance properties for those as
well.

But that gives you a workaround so that you can continue to use the
simple fins in your parametric study.

Apologies that I didn't think of that immediately.
