The following should make it work..

Construction,
    shaded construction,     !- Name
    Shade,                   !- Outside Layer
    GlassSimple;             !- Layer 1

Also, per the IO reference, field "Shading Device Material Name" in WindowProperty:ShadingControl is required if "Construction with Shading Name" is not specified. So instead of putting "Shade", this field should be left blank here.
