Hey, I want to model a simple shading control (exterior shade). Tutorial from bigladder: Method 2:
Define the Construction of the window without the shade, the so-called “bare” construction.
Reference the bare construction in the FenestrationSurface:Detailed for the window.
Define the WindowMaterial:Shade.
Define another Construction, called the “shaded construction,” that includes the WindowMaterial:Shade.
Define a WindowProperty:ShadingControl for the window in which you (a) reference the shaded construction and (b) specify how the shade is controlled
I have the following obejects within the model:
WindowMaterial:Shade,

0.2, !- Infrared Hemispherical Emissivity {dimensionless}
0.2, !- Infrared Transmittance {dimensionless}
0.002, !- Thickness {m}
1, !- Conductivity {W/m-K}
0.05, !- Shade to Glass Distance {m}
0.5, !- Top Opening Multiplier
0.5, !- Bottom Opening Multiplier
0.5, !- Left-Side Opening Multiplier
0.5, !- Right-Side Opening Multiplier
; !- Airflow Permeability {dimensionless}

I get the following error message:
** Severe ** CheckAndSetConstructionProperties: The single-layer window construction=SHADED CONSTRUCTION has a gas, complex gap, shade, complex shade, screen or blind material; it should be glass of simple glazing system.
** Warning ** WindowProperty:ShadingControl="SHADECONTROL" Both Construction with Shading Name and Shading Device Material Name are specified.
** ~~~ ** The Construction with Shading Name="SHADED CONSTRUCTION" will be used.
** Fatal ** GetSurfaceData: Errors discovered, program terminates.
Thank you for your help!
