BuildSysPro.BoundaryConditions.Solar.Irradiation.LightTransCoeff uses the Real equality operator outside of a function.

BuildSysPro.BoundaryConditions.Solar.Irradiation.LightTransCoeff uses the == operator on Real values, which is illegal according to the Modelica Specification section 3.5. == can only be used to compare Reals inside functions.
Let me know if you want me to try and find other occurrences of this issue.

I couldn't find any other such cases by validating the examples in the library.
