I trying to model a electrochromic glazing in which the transmittance and reflectance of the glass is controlled electronically.

According with I/O Reference I have to do:

"If you choose the Shading Type = SwitchableGlazing option for WindowShadingControl, the unswitched (clear) state is specified by the Construction referenced by the window and the switched (dark) state is specified by the Construction referenced by WindowShadingControl for that window. For example, if you specify Shading Type = SwitchableGlazing and Shading Control Type = OnIfHighSolarOnWindow, then the glazing will switch to the dark state whenever the solar radiation striking the window exceeds the Setpoint value."

The construction "Shading" have the characteristics of the switched (dark) state.

When I trie do run I get the following error message:

Program Version,EnergyPlus, Version 9.4.0-998c4b761e, YMD=2022.08.02 11:32,

Can anybody help me.
